Introduction: Green tea and tocopherol are potent antioxidants used to treat melasma. However, whether green tea or tocopherol is superior remains unclear. Objective: To compare the effectiveness between green tea and tocopherol in decreasing the amount of melanin and tyrosinase level in wistar rats exposed to UVB rays.Methods: The experimental study took 30 male Wistar rats randomly and divided them into 3 groups. The control group (C-G) was given basic topical cream, GT-G was given green tea topical cream and TC-G was given tocopherol topical cream. All rats were exposed to UVB every Monday, Wednesday and Friday for 4 weeks, whereas topical creams were smeared every day. Topical creams smearing on the same day with UVB exposure was performed 20 minutes before exposure and 4 hours after UVB exposure. The doses of UVB were 50 mJ/cm2 in first week, 70mJ/cm2 in the second week and 80mJ/cm2 in the third and fourth weeks. The amount of melanin was measured using pixel method and the tyrosinase level was measured using ELISA.Results: Anova analysis indicates that the amount of melanin and tyrosinase level are significantly different between groups, p<0.05. Post Hoc LSD analysis indicates that the amount of melanin in GT-G and TC-G are significantly lower than that of C-G, p<0.05. The amount of melanin in GT-G is lower than that of TC-G, p<0.05. The tyrosinase level in GT-G is significantly lower than that of C-G and TC-G, p<0.05. Meanwhile, the tyrosinase level in TC-G is lower than that of C-G but insignificantly, p>0.05.� Conclusion: Green tea topical treatment is significantly capable of decreasing the amount of melanin and tyrosinase level better than tocopherol.

INTRODUCTION:Cervical cancer is a malignant infectious disease caused by Human Papilloma Virus (HPV) in the cervix. Fig and olive oil containing flavonoid has been shown to have antioxidant and anticancer activity.OBJECTIVE:This study aimed to evaluate antioxidant and cytotoxic activity of combined Ficus carica L. and Olea europeae L. against HeLa cervical cancer cells.METHODS: This is an experimental study with a post-test only control group design. The HeLa cells were divided into 5 groups: fig extract, olive oil, combined fig extract and olive oil (at the ratio of 1:3, 1:1, 3:1), positive control (doxorubicin). The cytotoxic and antioxidant activity were evaluated by using MTT Assay and DPPH, respectively. The cytotoxic results were analyzed using probit and antioxidant activity was analyzed by using linear regression to obtain IC50 values.RESULTS:The IC50 cytotoxic of fig extract, olive oil, combined fig extract and olive oil (at the ratio of 1:3, 1:1, 3:1) with positive control (doxorubicin) were 13063,915 �g/mL, 679,593 �g/mL, 1562,356 �g/mL, 746,923�g/mL, 563,626 �g/mL and 13,707 �g/mL respectively. The IC50 antioxidant of fig extract, olive oil, and combination of fig extract and olive oil (3:1) was 105.9272 ppm, 23.1276 ppm, and 21,0689 ppm respectively.CONCLUSION:The combination of fig extract and olive oil (3:1) was shown to have the highest antioxidant and cytotoxic activity against HeLa cervical cancer cells.

Introduction:Liver exposure to toxic substances will disrupt the metabolic system. Carbon tetrachloride (CCl4) is a hepatotoxic substance causing a liver damage. Continuous multi-stage countercurrent extraction(CMCE) propolis extract contains active balsamic substances, caffeic acid, phenethyl esters and flavonoids.Objective: to prove the effect of CMCE propolis extract on IL-1 levels and the hepatocyte histopathology findingsof male wistar rats�induced by CCl4.Methods:In the posttest only control group design, the total sample of 28 rats was divided into 4 groups: positive control group (K-0; standard feed); group P-1 (propolis3.6 mg/200 g); P-2 (propolis7.2mg/200gr and P-3 (propolis14.4mg/200g) were respectively given for 14 days,yet those on the 14thday were given CCl4. The IL-1 level was measured with the ELISA method, while the male wistar rats�hepatocyte histopathology findings was determined by the HE staining methods. IL-1 levelswere analyzed usingOne Way Anova test,followed by the Post Hoc LSD test. Hepatic cell histopathology was analyzed usingKruskal Wallis, followed by Mann-Whitney U.Results:Post Hoc LSD analysis shows that the levels of IL-1 in P-1 (983.54 �19.67), P-2 (841.58�19.47), and P-3 (755.50�31.63) are significantlylower thanthosein K-0 (1131.69�14.91) withp<0.05. Mann-Whitney U analysis shows that the hepatocyte histopathology in the P-1 group (2.55�0.39), P-2 (1.24�0.94) and P-3 (1.20�0.93) is significantlylower thanthatinK-0 (2.94�0.16) with p<0.05.Conclusion: The administration of CMCE propolis extract may reduce IL-1 levels and improve the male wistar rats�hepatic cell histopathologyinduced with carbon tetrachloride (CCl4).
