"Luka pada kulit dapat disebabkan oleh trauma, hasil tindik pada badan, dan bahkan prosedur operasi. Luka akan diperbaiki melalui beberapa tahapan dan proses untuk mengembalikan struktur kulit kembali normal. Namun, proses tersebut tidak selalu berjalan dengan normal dan dapat berkembang menjadi jaringan parut atau jaringan keloid sebagai akibat dari meningkatnya aktivitas fibroblas. Peningkatan aktivitas fibroblas ini akan menyebabkan meningkatnya kebutuhan energi dan oksigen sehingga keadaan hipoksia dapat terjadi dan menyebabkan pembentukan ROS yang dapat berujung pada keadaan stres oksidatif. Antioksidan bekerja untuk mengatasi masalah ini dan salah satu antioksidan adalah katalase. Riset ini bertujuan untuk melihat efek kondisi tersebut terhadap aktivitas katalase di jaringan keloid dan dibandingkan dengan jaringan normal sebagai kontrol yaitu prepusium. Sampel eksperimen adalah jaringan keloid yang didapatkan melalui insisi pada operasi dan jaringan prepusium melalui sirkumsisi masing-masing sejumlah 9 sample. Aktivitas spesifik katalase diukur melalui penurunan kadar H2O2 yang diuraikan oleh katalase dan dibaca serapannya dengan spectrophotometer pada panjang gelombang 280nm. Setelah mendapatkan data, data tersebut dianalisis secara statistik dengan software SPSS. Uji normalitas menunjukan distribusi data yang tidak normal sehingga dilanjutkan dengan uji non parametric yaitu tes MannWhitney. Hasil analisis dengan tes Mann-Whitney menunjukan hasil yang tidak signifikan (p value = 0.021) walaupun terdapat penurunan aktivitas spesifik katalase pada jaringan keloid jika dibandingkan dengan prepusium yaitu 0.528 dan 0.386 (U/mg protein) pada prepusium dan keloid. Hal ini dapat dikarenakan perbedaan reaksi catalase dalam kondisi akut dan kronik dimana stres oksidatif yang sudah terjadi di jaringan keloid dapat menyebabkan katalase tidak mampu mengkompensasi ROS pada jaringan dan keadaan stres oksidatif tersebut. Selain itu. terdapat juga kemungkinan peran dan intervensi dari antioksidan enzimatik yang lain. Kesimpulan penelitian terdapat penurunan aktivitas katalase namun secara statistik penurunan tersebut tidaklah signifikan.

Skin sores can be caused by trauma, body piercing results, and even surgical procedures. The wound will be repaired through several stages and processes to restore the structure of the skin back to normal. However, the process does not always run normally and can develop into scar tissue or keloid tissue as a result of increased fibroblast activity. This increase in fibroblast activity will cause an increase in energy and oxygen requirements so that hypoxia can occur and cause the formation of ROS which can lead to a state of oxidative stress. Antioxidants work to overcome this problem and one of the antioxidants is catalase. This research aims to see the effect of these conditions on the activity of catalase in keloid tissue and compared with normal tissue as a control, namely the prepusium. Experimental samples are keloid tissue obtained through incisions in surgery and prepusium tissue through circumcision of 9 samples each. The specific activity of catalase is measured by decreasing the H2O2 levels described by catalase and its absorption is read with a spectrophotometer at 280nm wavelength. After getting the data, the data is analyzed statistically with SPSS software. The normality test shows that the data distribution is not normal so it continues with the non parametric test, the Mann Whitney test. The results of the analysis with the Mann-Whitney test showed insignificant results (p value = 0.021) although there was a decrease in the specific activity of catalase in keloid tissue when compared with the prepusium which was 0.528 and 0.386 (U / mg protein) in the prepusium and keloid. This can be due differences in catalase reactions in acute and chronic conditions where oxidative stress that has already occurred in the keloid tissue can cause the catalase to be unable to compensate for ROS in the tissue and the oxidative stress state. Other than that. there are also possible roles and interventions of other enzymatic antioxidants. The conclusion of the research is that there is a decrease in catalase activity but statistically the reduction is not significant."

"Latar belakang: Akumulasi volume latihan fisik yang berlebihan (overtraining/OT), dalam jangka panjang dapat menimbulkan penurunan performa yang disebut overtraining syndrome (OTS). Patofisiologi OTS banyak dihubungkan dengan stress oksidatif, kondisi ketidakseimbangan antara radikal bebas dan antioksidan endogen, yang dapat berujung pada gangguan kardiovaskular. Beberapa penelitan menunjukkan bahwa stres oksidatif dapat dihambat melalui suplementasi antioksidan. Hibiscus Sabdariffa Linn. (H. sabdariffa) adalah tanaman yang mengandung antioksidan tinggi.
Tujuan: Melihat efek OT terhadap tingkat stress oksidatif jantung tikus dan efek pemberian H. sabdariffa terhadap stress oksidatif jantung tikus OT.
Metode: Studi eksperimental menggunakan 25 tikus Wistar dewasa, 8-10 minggu, 300-350 gr, diacak menjadi lima kelompok: Kontrol (C), Kontrol+Hibiscus (C-Hib), Latihan Aerobik (A), Overtraining (OT) dan Overtraining+Hibiscus (OT-Hib). Dosis H. sabdariffa yang diberikan: 500 mg/kgBB/hari. Latihan fisik (A dan OT) dilakukan 5x/minggu selama 11 minggu. Dihitung kadar MDA, SOD dan GSH pada jantung tikus menggunakan spektrofotometri dan Nox2 pada jantung tikus menggunakan ELISA pada akhir Minggu 11.
Hasil: Pada kelompok OT-Hib kadar MDA secara bermakna mengalami penurunan, kadar GSH secara bermakna mengalami peningkatan, didukung dengan kadar SOD yang cenderung meningkat, namun tidak signifikan, dan Nox2 mengalami peningkatan yang tidak signifikan.
Kesimpulan: Overtraining menyebabkan kondisi stres oksidatif pada jaringan jantung tikus dan pemberian suplementasi H. sabdariffa memiliki potensi menangani stres oksidatif pada jantung tikus overtraining

Background: Accumulation of overtraining/OT volume, in the long run can lead to decreased performance called overtraining syndrome (OTS). Pathophysiology of OTS is associated with oxidative stress, a condition of imbalance between free radicals and endogenous antioxidants, which can lead to cardiovascular disorders. Some research shows that oxidative stress can be inhibited through antioxidant supplementation. Hibiscus Sabdariffa Linn. (H. sabdariffa) is a plant that contains high antioxidants.
Objective: This study was to look at the effect of OT on rat heart oxidative stress levels and the effect of giving H. sabdariffa to oxidative stress in OT rats.
Methods: The study was an experimental study using 25 adult Wistar rats, 8-10 weeks, 300-350 gr, randomized into five groups: Control (C), Control + Hibiscus (C-Hib), Aerobic Exercise (A), Overtraining (OT ) and Overtraining + Hibiscus (OT-Hib). Dosage of H. sabdariffa given: 500 mg/kg/day. Physical exercise (A and OT) is given 5x/week for 11 weeks. Calculated levels of MDA, SOD and GSH using spectrophotometry and Nox2 using ELISA at the end of Week 11.
Results: In the OT-Hib group, MDA levels significantly decreased, GSH levels significantly increased, supported by SOD levels which tended to increase, but were not significant, and Nox2 experienced an insignificant increase.
Conclusion: Overtraining can causes oxidative stress conditions in rat heart tissue, and supplementation of Hibiscus sabdariffa Linn. can handle oxidative stress in overtraining rat's heart.

"Atlet melakukan aktivitas fisik secara terus menerus dengan intensitas tinggi. Keadaan ini diduga dapat mencetuskan terjadinya stres oksidatif yang diketahui berperan dalam mekanisme terjadinya beberapa penyakit. MDA diketahui sebagai salah satu marker terjadinya stres oksidatif. Sedangkan aktivitas SOD eritrosit dapat menggambarkan adaptasi sistem antioksidan terhadap latihan.
Tujuan: Mengetahui gambaran kadar MDA plasma dan aktivitas SOD eritrosit saat istirahat pada kelompok atlet sepakbola profesional Indonesia dan pengunjung pusat kebugaran sebagai kontrol.
Metode: Penelitian ini merupakan penelitian potong lintang dengan subyek kelompok atlet dan kelompok kontrol. Subyek kelompok atlet adalah pesepakbola dari salah satu klub peserta kompetisi sepakbola tertinggi di Indonesia, sedangkan kelompok kontrol dipilih secara acak dari pengunjung salah satu pusat kebugaran di Jakarta. Dari kedua kelompok akan dikumpulkan data karakteristik fisik, kebiasaan olahraga dan tingkat aktivitas fisik, diikuti dengan pengambilan darah untuk mengetahui kadar MDA dan aktivitas SOD, setelah subyek berpuasa 12 jam dan tidak melakukan aktivitas fisik berat (olahraga) sejak 24 jam.
Hasil: Karakteristik fisik kedua kelompok secara statistik tidak berbeda kecuali pada rerata nadi istirahat (P < 0,01). Hasil GPAQ menunjukkan kelompok atlet 100% tergolong tingkat aktivitas fisik tinggi, sedangkan kelompok kontrol hanya 57%. Kadar MDA kelompok atlet lebih tinggi daripada kontrol (P < 0,01), dan aktivitas SOD eritrosit kelompok atlet lebih rendah daripada kontrol (P < 0,05).
Kesimpulan: Kadar MDA plasma lebih tinggi dan aktivitas SOD eritrosit lebih rendah saat istirahat pada kelompok atlet dibandingkan kontrol. Hal ini mungkin disebabkan oleh perbedaan intensitas dan jenis aktivitas fisik yang biasa dilakukan.

Athletes perform continuous physical activity in high intensity. This situation expected to trigger oxidative stress, which is known to play a role in the mechanism of many diseases. MDA is known as one of oxidative stress markers and the activity of erythrocyte SOD illustrates the adaptation of antioxidant system to exercise.
Objective: To determine the plasma MDA level and erythrocyte SOD activity at rest on a group of Indonesian professional football athletes and fitness center visitors as control.
Methods: This is a cross sectional study with athlete and control group. The subject in athlete group were taken from one club participating in highest league of football competition in Indonesia, while the control group was randomly selected from visitors of one fitness center in Jakarta. Data of physical characteristics, exercise habits and physical activity levels, followed by blood sampling after 12-hours fasting and 24-hours refrain from high intensity physical activity (exercise) for 24 hours were collected from both group.
Results: The physical characteristics of both groups were not statistically different, except the resting heart rate of athlete group lower than controls (P < 0.01). The GPAQ analysis showed that the athletes physical activity level are all high, compare to 57% of control group . Mean plasma MDA in athlete group is higher than controls (P < 0.01), and erythrocyte SOD activity in athlete group is lower than controls (P < 0.05).
Conclusion: Plasma MDA were higher and erythrocyte SOD activity were lower in athletes compare to controls, during rest condition. This might be caused by the differences in the intensity and type of their usual physical activity.

"Latar belakang: Ketidak seimbangan dalam kadar antioksidan dan level radikal bebas dapat menyebabkan terjadinya stres oksidatif. Puasa sudah terbukti dapat meningkatkan kadar antioksidan dan menurunkan produksi radikal bebas, yang akan menghasilkan penurunan stres oksidatif. Selain itu, durasi waktu puasa juga mempengaruhi dampak puasa dalam menurunkan stres oksidatif. Banyak penelitian yang sudah membahas efek puasa tersebut, namun, belum diteliti pada jaringan jantung. Oleh sebab itu, penelitian ini ditujukan untuk meneliti perbedaan efek durasi puasa terhadap kadar katalase pada jaringan jantung kelinci New Zealand White. Metode: Sampel dibagi menjadi tiga kelompok berdasarkan perlakuan yang dilakukan selama satu minggu. Kelompok pertama, kelompok kelinci dengan pemberian pakan yang normal. Kelompok kedua, kelompok puasa intermiten dengan 16 jam periode puasa dan 8 jam periode makan. Kelompok terakhir, kelompok puasa berkepanjangan dengan 40 jam periode puasa dan 8 jam periode makan. Selanjutnya, absorbansi aktivitas katalase dan kadar protein diukur dengan spectrofotometer. Pembagian aktivitas katalase dengan kadar protein dilakukan untuk mendapatkan aktivitas spesifik katalase. Hasil: Rata-rata dari aktivitas spesifik katalase pada kelompok kontrol adalah 1,104 ± 0,244 UI/mg protein, rata-rata pada kelompok puasa intermiten adalah 0,892 ± 0,093 UI/mg protein, dan rata-rata pada kelompok puasa berkepanjangan adalah 1,126 ± 0,098 UI/mg protein dengan perbedaan yang tidak signifikan (p > 0,05). Kesimpulan: Perlakuan puasa intermiten dan puasa berkepanjangan selama satu minggu tidak memberikan pengaruh yang signifikan terhadap aktivitas spesifik enzim katalase pada jantung kelinci New Zealand White.

Introduction: An imbalance in the antioxidant and free radical levels will develop oxidative stress. Fasting has increased antioxidant levels and decreased free radical production, ultimately reducing oxidative stress. Furthermore, the duration of fasting is also known to have a role in decreasing oxidative stress. Previous studies have been done on the effect of fasting on oxidative stress, however, none has been done on the heart. Hence, this study is aimed to discover the difference of fasting duration on its effect towards catalase level in New Zealand White rabbits. Method: Samples are divided into three groups based on their treatment for a week. First, the control group with a regular feeding schedule. Second, intermittent fasting group with 16 hours of the fasting period and 8 hours of the feeding period. Lastly, prolonged fasting with 40 hours of fasting and 8 hours of feeding periods. Then, a spectrophotometer is used to calculate the catalase activity and protein level. A division of catalase activity by protein level is done to obtain specific catalase enzyme activity. Result: The mean of specific catalase activity in the heart of the control group sample are 1.104 ± 0.244 UI/mg protein, the mean in the intermittent fasting group are 0.892 ± 0.093 UI/mg protein, and the mean in the prolonged fasting group is 1.126 ± 0.098 UI/mg protein with an insignificant difference (p > 0.05). Conclusion: Neither intermittent nor prolonged fasting conducted in a period of one week will have significant effect on the specific catalase activity level in the heart of New Zealand White rabbit."

Pada hasil pemeriksaan SOD, ditemukan penurunan yang tidak signifikan pada kelompok Iso (p=0,106) dibandingkan kelompok normal. Pada kelompok Iso + ekstrak CA ditemukan penurunan aktivitias SOD yang tidak signifikan (p=0,490) dibandingkan kelompok Iso. Kesimpulan: Pada penelitian ini, belum dapat dibuktikan bahwa ekstrak air daun Centella asiatica memiliki efek kardioprotektif terhadap aktivitas SOD dan kadar MDA jaringan jantung tikus.

Introduction: Myocardial infarction (MI) is one of the common causes of morbidity and mortality in the world. One of the underlying mechanisms of MI is due to excessive production of oxygen reactive species (ROS) in cells and tissues. This phenomenon is also known as oxidative stress condition. Many therapies are being developed to overcome MI such as medicinal herbs. Centella asiatica has been known for its useful therapeutic potential. For instance, it has some antioxidant compounds which can help reduce free radicals by scavenging them. Thus, this study aimed to analyze the effects of Centella asiatica water extract against SOD activity and MDA levels in isoproterenol-induced myocardial infarction in rats. Method: In this study, we used available rat heart tissues in the laboratory which were part of the previous study. Subjects were devided into three treatment groups as follows: normal, Iso, and Iso + extract CA. Isoproterenol were administered at 85 mg/kg BW and Centella asiatica water extract were administered in the third group at 200 mg/kg BW on the previous study. Bradford tests were performed to measure the concentration of total protein in samples. Activity of SOD were assessed by EZ-SOD Assay Kit. While levels of MDA were assessed by the TBARS assay method. Result: According to the findings of the study, there were non-significant differences in MDA levels among subjects in three groups (p=0,105). There was a non-significant decrease in activity of SOD (p=0,106) in the Iso group compared to the normal group. Also, there was a non-significant decrease in activity of SOD (p=0,490) in the Iso + extract CA group compared to the Iso group. These results are not in accordance with previous studies.Conclusion: In this study, it has not been proven that Centella asiatica water extract has cardioprotective effects against activitiy of SOD and MDA levels in isoproterenol-induced myocardial infarction in rats. This is probably due to some different treatments from previous studies. "

"Sekitar 35% dari 901 orang dewasa yang menjalani pemeriksaan kesehatan secara rutin ditemukan mengalami NAFPD (nonalcoholic fatty pancreas disease). NAFPD berkaitan dengan manifestasi klinik (sindrom metabolik) MetS, adapun terapi yang diberikan sesuai dengan gejalanya seperti antihipertensi, statin, metformin dan faktor komorbid MetS, sehingga mungkin terjadi polifarmasi akibat multiterapi pengobatan. Dalam hal ini dibutuhkan obat tunggal yang dapat memperbaiki NAFPD pada tikus MetS salah satu kandidatnya yaitu 6-Gingerol. Tujuan dari penelitian ini untuk menganalisis efektifitas 6-Gingerol terhadap NAFPD akibat MetS melalui stress oksidatif pada organ pankreas tikus yang diinduksi HFD + Fruktosa 55% dan Streptozotocin 22mg/kg selama 8 minggu. Tikus yang mengalami sindrom metabolik diterapi dengan 6-Gingerol dosis 50,100 dan 200mg/kg selama 8 minggu. Setelah mencapai akhir terapi, serum dan jaringan pankreas di ambil dan di analisis kadar (tumor necrosis factor alpha) TNF-alpha, (interleukin-6) IL-6, (malondialdehyde) MDA, (glutathione peroxidase) GPx, amilase, akumulais lemak, ekspresi sel alfa dam beta pankreas sebagai parameter NAFPD. Hasil analisis menunjukan bahwa pemberian 6-Gingerol tidak dapat menurunkan aktivitas amilase serum, MDA, ekspresi mRNA IL-6, namun dapat meningkatkan aktivitas GPx, mengurangi akumulasi lemak, dan meningkatkan ekspresi insulin dan glukagon. Sehingga 6-Gingerol memiliki potensi sebagai agen terapeutik untuk memperbaiki NAFPD pada tikus MetS.

About 35% of 901 adults who underwent routine health checks were found to have (nonalcoholic fatty pancreas disease) NAFPD. NAFPD is related to the clinical manifestations of (metabolic syndrome) MetS, while the therapy given is according to the symptoms. The therapies include: antihypertensives, statins, metformin, and MetS comorbid factors. Polypharmacy may occur as a result of multitherapy treatment. In this case, a single drug, namely 6-gingerol, is needed to improve NAFPD in the MetS rats. The aim of this study was to analyze the effectiveness of 6-Gingerol against MetS-induced NAFPD through oxidative stress in the pancreas of rats induced by HFD + Fructose 55% and Streptozotocin 22mg/kg for 8 weeks. Metabolic syndrome rats were treated with 6-gingerol doses of 50, 100, and 200 mg/kg for 8 weeks. After reaching the end of therapy, serum and pancreatic tissue were collected and analyzed for levels of (tumor necrosis factor alpha) TNF-α, (interleukin-6) IL-6, (malondialdehyde) MDA, (glutathione peroxidase) GPx, amylase, fat accumulation, cell expression pancreatic alpha and beta as parameters of NAFPD. The results of analysis showed that administering 6-gingerol did not significantly reduce serum amylase activity, MDA, the relative expression of IL-6, but it increased GPX activity, reduced fat accumulation, and increased insulin and glucagon expression in pancreatic tissue. Thus 6-Gingerol has the potential as a therapeutic agent to improve NAFPD in the MetS."

"ABSTRAK
Endometriosis merupakan penyakit ginekologi ditandai dengan implantasi jaringan endometrium di luar rongga uterus, berhubungan erat dengan proses inflamasi kronis. Stres oksidatif menjadi aktivator terjadinya proses inflamasi kronis di endometriosis. Oktil galat terbukti lebih efektif menekan proses inflamasi dibandingkan asam galat dan heptil galat pada sel kultur primer endometriosis. Penelitian ini bertujuan menganalisis pengaruh oktil galat pada proses inflamasi dan stres oksidatif pada tikus Wistar model endometriosis. Tiga puluh ekor tikus Wistar dibagi menjadi tiga kelompok, yaitu kelompok uji, kontrol endometriosis dan kelompok normal. Kelompok uji dilakukan autotransplantasi lalu diberikan suspensi oktil galat dan CMC selama satu bulan. Kelompok endometriosis dilakukan autotransplantasi lalu diberikan larutan CMC selama satu bulan, sedangkan kelompok normal hanya dilakukan laparotomi. Seluruh tikus kemudian dieuthanasia, dari kelompok uji dan kontrol endometriosis diambil jaringan endometriosisnya sedangkan dari kelompok sehat diambil jaringan endometriumnya untuk dianalisis. Analisis MDA (Malondialdhyde) dan SOD (Superoxide Dismutase) dilakukan secara spektofotometri, kadar NF-ĸB dengan ELISA dan IL-1β (Interleukin-1 Beta) dengan LUMINEX. Pemberian oktil galat pada kelompok uji tidak menurunkan kadar MDA namun berpotensi menekan kondisi stres oksidatif dengan meningkatkan kadar SOD. Oktil galat terbukti menekan aktivasi NF-ĸB secara signifikan, namun tidak menekan kadar IL-1β. Oktil galat berperan sebagai antiinflamasi pada tikus Wistar model endometriosis dengan cara induksi peningkatan SOD dan hambatan langsung pada translokasi nuklear NF-ĸB.

ABSTRACT
Endometriosis is a gynecological disease characterized by the implantation of endometrial tissue outside the uterine cavity, related to the chronic inflammatory process. Oxidative stress activates the occurrence of chronic inflammatory in endometriosis. Octyl gallate is more effective in suppressing the inflammatory process than gallic acid and heptil gallate in primary endometriosis culture cells. This study aimed to analyze the effect of octyl gallate on the inflammatory process and oxidative stress in endometriosis Wistar rat models. 30 Wistar rats were divided into three groups, the test group, endometriosis control and normal groups. The test group was autotransplantated and then given a suspension of octyl galate and CMC for one month. The endometriosis group was autotransplanted and then given a CMC solution for one month, while the normal group only underwent laparotomy. All rats were then euthanized, from the test and endometriosis group the endometriosis tissue was taken while from the normal group endometrial tissue was taken for analysis. MDA and SOD were measured using spectrophotometry, NF-ĸB with ELISA and IL-1β with LUMINEX. Induction of octyl gallate in the test group did not reduce MDA levels but could potentially suppress oxidative stress conditions by increasing SOD levels. Octyl gallate significantly inhibit the NF-ĸB activation, but not suppressing IL-1β levels significantly. Octyl gallate act as anti-inflammatory agent in endometriosis Wistar rat model through the enhancement of SOD and direct inhibition to nuclear translocation of NF-ĸB."

"[ABSTRAK
Latar Belakang: Endometriosis diperkirakan ditemukan pada 2-22% wanita usia reproduksi yang asimptomatik, sedangkan pada wanita yang mengalami dismenore, prevalensinya meningkat menjadi 40-60%. Terapi yang ada saat ini adalah terapi medikamentosa, terapi pembedahan, atau gabungan dari keduanya. Namun belum ada yang dapat berhasil menghilangkan penyakit ini. Hal ini dibuktikan dengan angka kekambuhan endometriosis yang cukup tinggi, yaitu 33,3-40,3%. Pada penderita endometriosis, terjadi proses inflamasi akibat adanya stress oksidatif yang berasal dari perdarahan siklik. Pada perdarahan siklik ini didapatkan heme dan besi yang merupakan suatu oksidan. Beratnya stress oksidatif yang terjadi dapat dilihat dari kadar malondialdehida dalam darah karena radikal bebas yang merupakan bagian dari ROS akan mengubah asam lemak jenuh menjadi aldehid dan malondialdehida (MDA). Telah diketahui bahwa kadar MDA pada jaringan endometriosis lebih tinggi secara bermakna dibandingkan dengan endometrium eutopik. Kurkumin diketahui mempunyai efek antiinflamasi, antioksidan, dan imunomodulator. Efek antioksidan dari kurkumin bekerja dengan cara mengurangi jumlah radikal bebas yang beredar.
Tujuan: Menilai pengaruh pemberian kurkumin terhadap stress oksidatif pada penderita endometriosis.
Metode: Penelitian ini merupakan suatu penelitian uji klinis acak tersamar ganda dengan kontrol pasien yang mendapat kapsul plasebo selama periode Desember 2014 ? Mei 2015. Pengambilan sampel dilakukan dengan consecutive sampling.
Hasil: Sejumlah 12 subjek dari kelompok kurkumin diberikan perlakuan dengan 1x100 mg kurkumin selama 2 bulan, sedangkan 12 subjek pada kelompok kontrol diberikan kapsul plasebo selama 2 bulan, setelah sebelumnya diambil MDA pre perlakuan. Satu pasien dari kelompok kurkumin dan 2 dari kelompok kontrol drop-out karena tidak kembali pada akhir bulan kedua untuk pengambilan MDA pasca perlakuan. Rerata awal kadar MDA subjek kelompok plasebo adalah 0,39 ± 0,39 nmol/ml dengan rerata kadar MDA di akhir intervensi 0,32 ± 0,14 nmol/ml. Penurunan tersebut tidak bermakna berdasarkan uji statistik dengan nilai p=0,80. Rerata awal (baseline) kadar MDA subjek dengan suplementasi kurkumin adalah 0,33 ± 0,21 nmol/ml dengan rerata kadar MDA pasca intervensi berkurang menjadi 0,31 ± 0,13 nmol/ml. Secara statistik penurunan kadar MDA pasca suplementasi kurkumin tidak bermakna (p=0,84). Tidak didapatkan perbedaan bermakna kadar MDA awal antar kedua kelompok (p=0,56). Demikian juga pada kadar MDA akhir intervensi dan perubahan (delta) kadar MDA antar kedua kelompok setelah intervensi, tidak dijumpai berbedaan bermakna secara statistik dengan p=0,85 dan p=0,81, berturut-turut
Kesimpulan: Tidak terdapat penurunan kadar MDA yang bermakna pada subjek dengan suplementasi kurkumin maupun plasebo.

ABSTRACT
Background: Endometriosis is estimated to be found in 2-22% asymptomatic reproductive women, while women with dysmenorrhea, the prevalence increased to 40-60%. Current management is medical therapy, surgical therapy, or a combination of both. But no one has been able to successfully eliminate this disease. This is proven by endometriosis recurrence rate is high enough, ranging from 33.3 to 40.3%. In endometriosis, inflammatory process occurs as a result of oxidative stress originating from cyclic bleeding. At this cyclic bleeding obtained heme and iron which is an oxidant. Free radicals that are part of the ROS (reactive oxygen species) will change the saturated fatty acids to aldehydes and malondialdehydes (MDA), so oxidative stress that occurs can be seen from plasma malondialdehyde levels. In recent study, MDA levels in endometriosis tissue was significantly higher than the eutopic endometrium. Curcumin is known to have anti-inflammatory, antioxidant and immunomodulatory effects. Antioxidant effects of curcumin works by reducing the amount of circulating free radicals.
Objective: Assess the effect of curcumin on oxidative stress in endometriosis patients
Methods: This study is a randomized double-blind clinical trial with control groups receiving placebo capsules for the period December 2014 - May 2015. Sampling was conducted by consecutive sampling.
Results: Twelve subjects of the treatment group was given curcumin 1x100 mg, while 12 subjects in the control group was given placebo capsules for 2 months. Peripheral blood was taken for MDA levels pre treatment. One patient from curcumin group and 2 from the control group dropped out because they do not come at the end of treatment for MDA measurement. The mean initial MDA level of placebo group was 0.39 ± 0.39 nmol / ml with a mean MDA levels at the end of the intervention 0.32 ± 0.14 nmol / ml. The decrease was not statistically significants with p = 0.80. The mean initial MDA levels of curcumin group was 0.33 ± 0.21 nmol / ml with a mean at the end of intervention was 0.31 ± 0.13 nmol / ml. The decrease was not statistically significants with p = 0.84. There were no significant differences between the initial MDA levels both groups (p = 0.56). Likewise, at MDA levels post intervention and delta between the MDA pre and post intervention on both groups, found no statistically significant with p = 0.85 and p = 0.81, respectively.
Conclusions: There was no significant decrease in MDA levels in subjects with curcumin supplementation or placebo., Background: Endometriosis is estimated to be found in 2-22% asymptomatic reproductive
women, while women with dysmenorrhea, the prevalence increased to 40-60%. Current
management is medical therapy, surgical therapy, or a combination of both. But no one has
been able to successfully eliminate this disease. This is proven by endometriosis recurrence
rate is high enough, ranging from 33.3 to 40.3%. In endometriosis, inflammatory process
occurs as a result of oxidative stress originating from cyclic bleeding. At this cyclic bleeding
obtained heme and iron which is an oxidant. Free radicals that are part of the ROS (reactive
oxygen species) will change the saturated fatty acids to aldehydes and malondialdehydes
(MDA), so oxidative stress that occurs can be seen from plasma malondialdehyde levels. In
recent study, MDA levels in endometriosis tissue was significantly higher than the eutopic
endometrium. Curcumin is known to have anti-inflammatory, antioxidant and
immunomodulatory effects. Antioxidant effects of curcumin works by reducing the amount
of circulating free radicals.
Objective: Assess the effect of curcumin on oxidative stress in endometriosis patients
