ABSTRAK
Peradangan kronik saluran cerna seperti Inflammatory Bowel Disease (IBD) berisiko menjadi karsinoma kolorektal, disebabkan oleh ketidakseimbangan mikrobiota komensal dan patogen. Dadih sebagai probiotik dapat mempertahankan keseimbangan mikrobiota usus sehingga mengurangi risiko radang usus. Untuk melihat keefektifan probiotik susu kerbau hasil fermentasi lokal berasal dari Sumatera Barat yang mengandung Bakteri Asam Laktat, dilakukan penelitian menggunakan hewan coba. Desain penelitian eksperimental menggunakan 4 kelompok mencit Balb/c terdiri dari 6 ekor per kelompok yakni, kelompok normal diberi aquades 8 minggu, kelompok (+) dadih diberi dadih 8 minggu (112 mg/20g/BB), kelompok (+) DSS mencit diberi DSS konsentrasi 3% sebanyak 3 siklus 6 minggu, serta kelompok uji diberi dadih 8 minggu dan DSS sebanyak 3 siklus. Mencit kemudian di-euthanasia dan diambil darah intrakardiak. Kadar sitokin TNF-alpha, IL-1β dan IL-10 diperiksa menggunakan Luminex dari serum. Dadih yang digunakan mengandung bakteri Lactococcus lactis subsp. lactis sebanyak 3x107 CFU/gram. Ada beda signifikan kadar TNF-alpha (p=0,033) dan IL-1β (p=0,007) antar kelompok namun tidak terdapat perbedaan signifikan IL-10 antar kelompok (p=0,091). Serta, ada beda signifikan kadar sitokin TNF-alpha mencit diberi dadih dan DSS dengan median kadar sitokin 26,641 (16,027-35,206) lebih rendah dibandingkan mencit yang hanya diberi DSS 41,220 (36,226-101,920) namun, median kadar sitokin IL-10 lebih tinggi sebesar 109,951 (92,621-130,436) dibandingkan mencit DSS sebesar 85,164 (57,292-111,548) serta tidak terdapat perbedaan signifikan untuk IL-1β. Dadih sebagai probiotik dapat meningkatkan kadar sitokin anti-inflamasi dan menurunkan sitokin pro-inflamasi dalam keadaan radang. Sehingga dapat disimpulkan bahwa dadih dapat digunakan untuk mencegah terjadinya peradangan usus.

ABSTRACT
Chronic inflammation in the gastrointestinal tract, such as Inflammatory Bowel Disease (IBD), is a risk factor for colorectal cancer (CRC) causes the imbalance between commensal and pathogen microbiota in the intestine. Dadih could improve the balance between commensal and pathogen bacteria, and also between pro-inflammatory and anti-inflammatory responses. Aim of this research is to see the effectiveness of probiotic made from locally fermented buffalo milk originating from West Sumatra using animal model. This in vivo experimental research used 4 groups of Balb/c mice consisted of 6 mice per group there are normal group mice indued by aquades for 8 weeks, DSS(+) group mice induced by dadih for 8 weeks with doses 112mg/20g/BB, DSS(+) group mice induced DSS with concentration 3% as much as 3 cycle for 6 weeks and the last treatment group mice induced dadih for 8 weeks and DSS dor 6 weeks. The further more, mice doing euthanasia and taking blood to get the serum. Serum will be using for cytokine investigation consist of TNF-alpha, IL-1β and IL-10 with Luminex. The results showed dadih contained Lactococcus lactis ssp. lactis with 3x107 CFU/gram. The significant differences in TNF-alpha and IL-1β level with p = 0,033 and 0.007 respectively. However, there was no significant difference in IL-10 (p = 0.091). A further test was conducted to see the differences between groups the results showed that there were significant differences in TNF-alpha mice induced dadih+DSS group has median cytokine lower than DSS group equal to 26,641 (16,027-35,206) than 41,220 (36,226-101,920) but IL-10 cytokine dadih+DSS group has higher median cytokine 109,951 (92,621-130,436) than DSS group has 85,164 (57,292-111,548), but was no significant different at IL-1β cytokine. This research showed that dadih could enhance anti-inflammatory cytokines and suppress pro-inflammatory cytokines. Therefore, as locally made probiotic, dadih could be used to prevent intestinal inflammation.

Hipertensi merupakan salah satu kondisi medis yang cukup serius karena dapat meningkatkan risiko penyakit jantung, otak, ginjal dan penyakit lainnya. Wilayah di DKI Jakarta dengan prevalensi hipertensi tertinggi berdasarkan diagnosis dokter yaitu Kota Jakarta Pusat sebesar 12,16%. Partikulat meter organik dan komponen partikulat meter dapat memicu proinflammatory effects pada paru-paru karena kemampuannya mengakibatkan stress oksidatif. Penelitian ini bertujuan untuk menyusun model pengaruh pajanan PM2,5 di udara ambien terhadap kejadian hipertensi melalui stress oksidatif dan sitokin inflamasi pada penduduk di Jakarta Pusat. Penelitian dilakukan pada penduduk dewasa (18-65 tahun) di Kota Jakarta Pusat dengan disain studi hybrid cross sectional ecology. Pengumpulan data secara cluster random sampling dengan analisis data dilakukan melalui pemodelan regresi logistik multilevel dan cox regresi proporsional hazard. Hasil analisis menunjukkan terdapat asosiasi antara PM2,5 di udara ambien dengan biomarker stress oksidatif (IOR PM2,5: 2,185173-2,185176) dan dengan biomarker sitokin inflamasi (IOR PM2,5: 1,21-1,91). Pemodelan multivariat dengan cox regresi proporsional hazard menunjukkan bahwa variabel umur dan indeks massa tubuh merupakan confounder hubungan antara stress oksidatif dengan hipertensi dan antara sitokin inflamasi dengan hipertensi dengan nilai Rasio Prevalens adjusted (95% CI) masing-masing sebesar 1,19 (0,69-2,03) dan 0,99 (0,58-1,72). Dapat disimpulkan bahwa variabel konsentrasi PM2,5 di udara ambien memiliki peran terhadap terjadinya hipertensi, stress oksidatif dan sitokin inflamasi pada penduduk di Jakarta Pusat. ......Hypertension is a serious medical condition that can increase the risk of heart, brain, kidney and other diseases. The area in DKI Jakarta with the highest prevalence of hypertension based on doctor diagnosis is Central Jakarta city about 12.16%. Organic particulate matters and particulate matter components can trigger proinflammatory efects in the lung due to their ability to cause oxidative stress. This study aims to develop a model of the Influence of PM2,5 Exposure in Ambient Air on Hypertension Occurrence through Oxidative Stress and Inflammatory Cytokines among residents in Central Jakarta. The study was conducted among adult residents (age 18-65 years) in Central Jakarta with hybrid cross sectional study design. Data collected using cluster random sampling with data analysis carried out through multilevel logistic regression modeling and cox proportional hazard regression. Results show there is an association between PM2.5 in ambient air with oxidative stress biomarkers (IOR PM2.5: 2.185173-2.185176) and with inflammatory cytokine biomarkers (IOR PM2.5: 1.21-1.91). Multivariate modeling with Cox regression proportional hazard shows that age and body mass index are confounders of the relationship between oxidative stress with hypertension and between inflammatory cytokines with hypertension with an adjusted prevalence ratio (95% CI) value of 1.19 (0.69-2.03) and 0.99 (0.58-1.72). It can conclude that concentration of PM2.5 in ambient air has a role on hypertension, oxidative stress and inflammatory cytokine among residents in Central Jakarta.

Kondisi hipoksia hipobarik dapat mengganggu kesehatan manusia dan menjadi risiko keselamatan di dunia penerbangan. Berbagai jalur pensinyalan sensitif oksigen pada tingkat seluler, dapat diaktifkan selama paparan hipoksia hipobarik intermiten (HHI). HSP sebagai chaperokine berperan dalam transduksi sinyal dan modulasi sistem imun serta terkait dengan produksi sitokin pro-inflamasi atau anti-inflamasi. Penelitian ini bertujuan menganalisis efek HHI terhadap HSP70 dan produksi sitokin pro dan anti-inflamasi. Penelitian ini merupakan penelitian eksperimental dengan menggunakan jaringan hepar tikus Sprague-Dawley yang disimpan pada suhu -20°C. Tikus dibagi menjadi 5 kelompok yaitu kontrol (C), HHA, HHI1, HHI2, dan HHI3 dan diberikan paparan HHI pada ketinggian 25.000 kaki selama 5 menit. Analisis konsentrasi protein dan sitokin ditentukan dengan metode sandwich ELISA. Hasil penelitian menunjukkan terdapat perbedaan bermakna ekspresi protein HSP70 pada hepar tikus pada kelompok HHA dan HHI terhadap kontrol (p<0.05), terdapat perbedaan bermakna konsentrasi IL-10 antara kelompok HHI3 terhadap kontrol (p = 0,018), dan adanya korelasi positif dengan kekuatan korelasi sedang antara HSP70 dengan TNF-α dan IL-1β, serta korelasi positif sedang HSP70 dengan IL-10. HHI menginduksi peningkatan HSP70 sebagai mekanisme adaptasi dan memodulasi sistem imun tubuh untuk meningkatkan konsentrasi IL-10. ......Hypobaric hypoxic conditions can disrupt human health and become a risk for safety of aviation. Various signaling oxygen-sensitive pathways at the cellular level can be activated during intermittent hypobaric hypoxia (IHH) exposure. HSP as a chaperokine plays a role in signal transduction and modulation of the immune system and it is associated with the production of pro-inflammatory or anti-inflammatory cytokines. This study aims to analyze the effect of IHH on HSP70 and the production of pro- and anti-inflammatory cytokines. This study was an experimental study using Sprague-Dawley rat liver tissue stored at -20°C. Rats were divided into 5 groups, they are control (C), AHH, IHH1, IHH2, and IHH3. They were exposed to IHH at altitude of 25,000 feet for 5 minutes. Analysis of protein and cytokines concentrations was determined by the sandwich ELISA method. The results showed that there was a significant difference in HSP70 protein expression in the liver of rats in the HHA and IHH groups compared to the control (p<0.05), there was a significant difference in IL-10 concentration between the IHH3 group compared to the control (p = 0.018), a positive correlation with moderate correlation strength between HSP70 with TNF-α and IL-1β, and a moderate positive correlation between HSP70 with IL-10. HHI produces an increase in HSP70 as an adaptive mechanism and modifies the immune system to raise the levels of IL-10.
