Aims: This sudy aims to determine the effect infusion  of green tea (Camellia sinensis) to the renal histopathology picture of male white rats (Rattus norvegicus) Sprague dawley strain ethanol-induced. Methods: This study used 30 rats divided into 5 groups. The negative control (K-) was given distilled water 2 mL/day, the positive control (K +) was given ethanol 2 mL/day, the treatment group (P1, P2, P3) was given ethanol 2 mL and green tea infusion with respective doses of 0.375, 0.75 and 1.5 grams orally for 14 days. Then the renal retrieval is done to be examined microscopically. Results: The mean kidney damage score obtained was K- = 0.36; K + = 3.24; P1 = 2.52; P2 = 2,4; and P3 = 2.2. Data analysis with One Way Anova Test and continued with Pos Hoc and found significant differences in K- to K+, P1, P2, P3; K+ is significant to K-, P1, P2, P3; and P1, P2, P3 are significant to K- & K+. Conclusion: There is an effect of infusion of green tea (Camellia sinensis) on the renal histopathological picture of male white rats (Rattus norvegicus) ethanol-induced Sprague dawley strain.

Aims: This research aims to determine the effect of green tea infusion (Camellia sinensis) on the hitopathology of white rat liver induced by ethanol. Method: This study used 30 rats divided into 5 groups as follow negative control group (K1) given aquades, positive control group (K2) given 20% 2 mL/day peroral, treatment group 1, 2, 3 (P1, P2, P3) given 20% ethanol 2 mL/day peroral followed by green tea infusion with doses 0,375 g/day, 0,75 g/day, and 1,5 g/day single dose per oral for 14 days. The the liver of the rat is taken for microscopic examination. The mean Manja Roenigk scores obtained were K1=1,16, K2=3,36, P1=2,8, P2=2,68, and P3=2,56. Data were tested with the Kruskal-wallis test followed by Mann whitney’s post hoc test. Results:  The results showed a significant mean difference between positive group (K2) and the treatment group P1, P2, and P3. There is no significant mean difference between P1-P2, P1-P3, and P2-P3 which means giving green tea infusion (Cameliia sinensis) in P2 and P3 gave almost the same effect as P1. Conclusion: There is an effect of giving green tea infusion (Camellia sinensis) to the histopathology of white rat liver induced by ethanol.
