| Abstract: | Penelitian ini bertujuan untuk menentukan efek senyawa 7,12-dimetilbenz(a)antrasena (DMBA) pada tikus betina galur Sprague-Dawley dan efektivitas Phomopsis sp. sebagai antioksidan. Metode penelitian melibatkan pengukuran kadar malondialdehida (MDA), dan aktivitas enzim hati (ALT dan AST). Hasil penelitian menunjukkan bahwa DMBA meningkatkan kadar radikal bebas yang ditandai dengan meningkatnya kadar MDA secara signifikan menjadi 27,25 ± 6,11 nm/g hati (Kontrol negatif), dan terbukti bahwa Phomopsis sp. mampu menurunkan kadar MDA sampai 11,71 ± 1,42 nm/g hati dengan dosis 40mg/kg bb. Aktivitas enzim ALT dan AST juga meningkat walau tidak signifikan pada kelompok yang diinduksi DMBA sebesar 38,89 ± 7,66 U/L dibandingkan Kelompok Normal sebesar 34.97 ± 3.35 U/L . Sementara itu, Phomopsis sp. dosis 40mg/kg bb berbeda signifikan dengan nilai ALT mencapai 67,97 ± 11,79 U/L dan AST mencapai 75,66 ± 1,53 U/L. Namun, pemberian Phomopsis sp. dosis 10mg/kg bb dan 20mg/kg bb dapat menurunkan aktivitas enzim ini. Simpulan penelitian ini menunjukkan bahwa Phomopsis sp. memiliki potensi sebagai antioksidan yang efektif dalam mengurangi stres oksidatif akibat paparan DMBA. This study aimed to determine the effects of 7,12-dimethylbenz(a)anthracene (DMBA) compound on female Sprague-Dawley rats and the effectiveness of Phomopsis sp. as an antioxidant. The research methods involved the measurement of malondialdehyde (MDA) levels, and liver enzyme activities (ALT and AST). The results showed that DMBA increased the levels of free radicals characterized by increasing MDA levels significantly to 27,25 ± 6,11 nm/g liver from the Negative Control, and it was proven that Phomopsis sp. was able to reduce MDA levels to 11,71 ± 1,42 nm/g liver at a dose of 40mg/kg bw. ALT and AST enzyme activities also increased although not significantly in the DMBA-induced group at 38,896 ± 7,661 U/L compared to the Normal Group at 34,96 ± 3,35 U/L . Meanwhile, Phomopsis sp. with 40mg/kg bw dosage was significantly different with values reaching 67,97 ± 11,79 U/L and AST reaching 75,66 ± 1,53 U/L. However, the administration of Phomopsis sp. 10mg/kg bw and 20mg/kg bw can reduce the activity of these enzymes. The conclusion of this study shows that Phomopsis sp. has the potential as an effective antioxidant in reducing oxidative stress due to DMBA exposure. |
