Hati merupakan satu organ yang paling penting dalam metabolisme tubuh. Kerusakan pada hati dapat berdampak pada abnormalitas aktivitas enzim yang berperan dalam metabolisme di serum, seperti enzim Aspartate minotransferase (AST) dan alanine aminotransferase (ALT). Namun, terapi untuk mengobati penyakit hati masih belum memuaskan. Oleh karena itu, pencegahan penyakit hati menjadi hal yang penting. Oncom merupakan makanan fermentasi tradisional Indonesia yang diketahui memiliki efek antioksidan tinggi. Penelitian ini dilakukan untuk menilai efek hepatoprotektif ekstrak oncom melalui pengamatan terhadap aktivitas AST dan ALT serum. Dua puluh empat ekor tikus Sprague-Dawley jantan dibagi menjadi 6 kelompok, yaitu (1) kontrol tanpa intervensi; (2) kontrol negatif yang diberi CCl4; (3) oncom merah; (4) oncom merah dan CCl4; (5) oncom hitam; dan (6) oncom hitam dan CCl4. Ekstrak oncom diberikan dengan dosis 1 gram/kgBB/hari selama 1 minggu. CCl4 diberikan dengan dosis 0,55 mg/kgBB sehari setelah perlakuan selesai. Sampel serum tikus diambil 2 hari setelah pemberian CCl4. Hasil uji Post-Hoc LSD pada aktivitas AST menunjukkan terdapat perbedaan yang signifikan antara kelompok CCl4 dengan kelompok oncom merah dan CCl4 (p= 0,019). Hasil uji One-way Anova pada aktivitas ALT menunjuukan tidak terdapat perbedaan antar kelompok (p= 0,238). Kesimpulannya, pemberian oncom merah memberikan efek hepatoprotektif terhadap aktivitas AST yang signifikan dari paparan CCl4. ......Liver is one of the most important organs in the body metabolism. Damage to the liver can have a impact on abnormal enzyme activity involved in metabolism, such as aspartate aminotransferase (AST) and serum alanine aminotransferase (ALT). However, the therapies to treat liver diseases are still not satisfactory. Therefore, prevention of liver disease is important. Oncom is a traditional Indonesian fermented food which is known to have high antioxidant effects. This study was conducted to assess the hepatoprotective effect of oncom extract by observing the activity of serum AST and ALT. Twenty four male Sprague-Dawley rats were divided into 6 groups, namely (1) control without intervention; (2) negative controls given CCl4; (3) red oncom; (4) red oncom and CCl4; (5) black oncom; and (6) black oncom and CCl4. Oncom extract was given at a dose of 1 gram / kgBW / day for 1 week. CCl4 was given at a dose of 0.55 mg / kgBW a day after the treatment is complete. Rat serum samples were taken 2 days after CCl4 administration. The LSD Post-Hoc test results on AST activity showed that there were significant differences between CCl4 group with red oncom and CCl4 groups (p= 0.019). One-way ANOVA test results on ALT activity showed no differences between groups (p = 0.238). In conclusion, administration of red oncom gave a significant hepatoprotective effect on AST activity after CCl4 exposure.

Latar belakang: Sel punca mesenkim (SPM) telah menjadi salah satu alternatif untuk menghambat proses fibrosis dan memperbaiki fungsi hati. Berbagai jalur dapat digunakan untuk pemberian SPM, namun belum banyak studi yang membandingkan jalur pemberian. Pada studi ini dibandingkan pemberian SPM intrahepatika dan intrasplenika terhadap fungsi hati dan derajat fibrosis hati Oryctolagus cuniculus ligasi duktus bilier. Metode penelitian: Penelitian ekperimental dengan menggunakan model hewan kelinci (Oryctolagus cuniculus) yang dilakukan ligasi duktus bilier (LDB). Kelinci dibagi ke dalam 4 kelompok, yaitu kelompok sham surgery, LDB, injeksi SPM intrahepatika(LDB + SPM IH) dan injeksi SPM intrasplenika (LDB + SPM IS). Injeksi SPM tali pusat dilakukan pada hari kelima LBD, kemudian kelinci diobservasi sebelum diterminasi seluruhnya pada hari ke-14. Dinilai fungsi hati yang dinilai dengan kadar serum AST, ALT, bilirubin total dan direk, serta derajat fibrosis hati yang dinilai dengan skor Laennec.   Hasil penelitian: Dari total 23 kelinci, dibagi menjadi 4 kelompok, yaitu kelompok sham 2 ekor dan masing-masing 7 ekor untuk kelompok LDB, LDB + SPM IH, dan IS. Didapatkan mortalitas sebesar 57,1% pada kelompok LDB, mortalitas 14,3% pada kelompok LDB + SPM IH dan mortalitas 28,6 pada kelompok LDB + SPM IS sebelum penelitian selesai. Tidak didapatkan perbedaan yang bermakna untuk fungsi hati seperti AST, ALT, bilirubin total, dan direk antarkelompok, namun terkesan median fungsi hati pada kelompok LDB lebih tinggi dibanding sham surgery, serta median kelompok LDB + SPM IH dan IS lebih menyerupai normal. Fungsi hati tampak lebih baik pada kelompok LDB + SPM IS dibanding LDB + SPM IH, meskipun secara statistik tidak bermakna. Pemeriksaan histopatologi kelinci yang dilakukan ligasi duktus bilier menunjukkan derajat fibrosis Laennec 4B, yang tidak berbeda antar ketiga kelompok. Area fraction fibrosis, jumlah hepatosit yang viabel dan nekrosis, serta jumlah sel progenitor dianalisis, tidak terdapat perbedaan yang ditemukan antara kelompok LDB + SPM IH dan LDB + SPM IS, namun kelompok yang diberikan SPM memiliki jumlah hepatosit viabel yang lebih banyak dibandingkan kelompok LDB. Kesimpulan: Pemberian SPM intrahepatika dan intrasplenika tidak berpengaruh pada fungsi hati dan derajat fibrosis hati Oryctolagus cuniculus pascaligasi duktus bilier. Pemberian SPM akan meningkatkan jumlah hepatosit yang viabel pada model cuniculus pascaligasi duktus bilier. ......Background: Mesenchymal stem cell (MSC) becomes an alternative to attenuate liver fibrosis and to improve liver function. A couple of administration route had been studied, but few compared one to another. This study aims to compare intrahepatic and intrasplenic route of administration of MSC in regards of liver function and degree of liver fibrosis in Oryctolagus cuniculus bile duct ligation model. Method: This is an experimental study using rabbit (Oryctolagus cuniculus) bile duct ligation model. The subjects were randomized into 4 groups: sham surgery, bile duct ligation (BDL), intrahepatic route of MSC (BDL + MSC IH), and intrasplenic route of MSC (BDL + MSC IS). Umbilical cord MSC was administered in the fifth day of bile duct ligation, and the subject was observed until terminated on 14th day post BDL. The liver function, such as AST, ALT, total and direct bilirubin were evaluated, and the degree of fibrosis was evaluated with Laennec score.  Result: The subjects were grouped into 4 group: 2 sham surgery, and each had 7 in BDL, BDL + MSC IH and BDL + MSC IH groups. Mortality rate in control group was 57,1%, mortality in BDL + MSC IH group was 14,3% and in BDL + MSC IS group was 28,6%. No significant difference was found regarding liver function in each group such as AST, ALT, total and direct bilirubin, but the median of liver function in BDL group seemed worse than in sham sugery group, and the median of liver function in BDL + MSC IH and BDL + MSC IS groups were closed to sham operated (normal). Liver function seemed to be better in BDL + MSC IS group compared to BDL + MSC IH group, but showed no statistical difference. Histopathology examination in subjects undergone bile duct ligation (regardless of MSC) show the degree of fibrosis of Laennec 4B. Fibrosis area fraction, the number of viable and necrosis hepatocyte, and progenitor cell are analysed; no significant difference was found between BDL + MSC IH and BDL + MSC IS group, but the group administered with MSC shows larger number of viable hepatocyte compared to BDL group. Conclusion: Administration of intrahepatic or intrasplenic MSC did not show significant improvement the liver function and liver fibrosis in Oryctolagus cuniculus bile duct ligation model. Administration of MSC would increase the number of viabel hepatocyte in Oryctolagus cuniculus bile duct ligation model.

Patients undergoing fixed orthodontic treatment are susceptible to dental plaque accumulation. Plaque can cause inflammation in gingiva. It could be assessed by aspartat aminotransferase (AST) in gingival crevicular fluid (GCF). Mouth rinse could be useful to reduce dental plaque accumulation during orthodontic treatment. Chlorhexidine gluconate is often used as mouth rinse in dental practice. n the other hand, green tea is one of natural ingredient that can be used for mouth rinse which is assumed could reduce plaque accumulation. Objectives: To compare the effect between green tea and chlorhexidine gluconate on AST activity in GCF in patient undergoing orthodontic treatment with molar band. Methods: An experimental study was conducted included forty adult subjects. They were randomized into two groups: green tea (n=20) and chlorhexidine gluconate (n=20). AST activity was measured before band insertion, 7 and 30 days after band insertion. One way and two-ways ANOVA were used to analyze the data. Results: The results showed significant difference of AST levels between before, 7 and 30 days after band insertion in the green tea groups (p<0.05). In contrast, there was no significant differences of AST levels between before band insertion, 7 and 30 days after band insertion in the chlorhexidine gluconate groups (p=0.049). There were no difference between each groups with two way ANOVA (p<0.05). Conclusions: Gargle effect of green tea was as effective as chlorhexidine gluconate in reducing AST levels related to banded first molars in adolescents undergoing orthodontic treatment.

Background: Thalassemia I² major is a disease with carrier gene common enough to be found in Indonesia therefore further research was needed to know the exact pattern and characteristics of thalassemia I² major because the patients has ineffective hematopoiesis depend their life with transfusion and chelation therapy to survive therefore it need further research to know the effect of chelation therapy for population in Indonesia with alanin aminotransferase, aspartat aminotransferase, and AST to platelet ratio index (APRI) score level.

Methods: This study used observative cross sectional method and all of the participants are patients at RSCM Kiara. Participants compliance were measured by morisky medication adherence scale-8 with some adjustment to know the reason why participants isnt complying with therapy and will be compared with laboratory result through electronic medical record then both results were then analyzed non-parametrically using Kruskal-Wallis followed by Mann-Whitney for Post-Hoc.

Results: There arent any correlation between chelation therapy compliance with aspartat aminotransferase, alanine aminotransferase, and AST to platelet ratio index score level but it has been found that age, transfusion duration, and type of chelator have some degree of correlation.

Conclusion: There arent any correlation between chelation therapy compliance with aspartat aminotransferase, alanine aminotransferase, and AST to platelet ratio index score level but the result need further research to confirm the result because this research has its own degree of limitation
