TRANSFORMING GROWTH FACTOR BETA OF TESTIS GERMINAL CELL IN GUINEA PIG (CAVIA PORCELLUS) AFTER EXPOSURE TO METHANOL EXTRACT OF THE SEEDS OF BITTER MELON (MOMORDICA CHARANTIA) AND DEPOT MEDROXYPROGESTERONE ACETATE

Objective: The discovery of male contraceptive drugs continues to be pursued, due to the very small participation of men associated with the lack of contraceptiveÃptions for men. The combination of methanol extract of bitter melon seed and depot medroxyprogesterone acetate (DMPA) becomes the choice that currently being pursued to be applied to men.Methods: The use of guinea pigs as experimental animals conducted research using experimental methods with complete randomized design. The study was divided into four control groups i.e K0; dimethylsulfoxide (DMSO) for 0 week (4 h),K1; Control group of DMSO for 4 weeks, K2; Control group of DMSO for 8 weeks, K3; Control group of DMSO for 12 weeks, and four treatment groups, i.e: group P0; bitter melon seed extract of 50 mg/100g body weight/day for 0 week (4 h), group P1; Bitter melon seed extract of 50 mg/100g BW/day for 4 weeks+DMPA, group P2; Bitter melon seed extract of 50 mg/100g BW/day for 8 weeks+DMPA, P3 group; Bitter melon seed extract of 50 mg/100g BW/day for 12 weeks+DMPA.Results: There was a significant effect (p<0.05) methanol extract of bitter melon seed to increase the transforming growth factor expression -β expression.Conclusion: The methanol extract of bitter melon seed was able to be candidate for herbal contraception

Pengaruh Ekstrak Methanol Biji Pare (Momordica Charantia) dan DMPA terhadap Jumlah Sel Purkinje Cerebellum Mencit (Mus Musculus L.)

Perubahan jumlah sel purkinje cerebellum mencit dapat dijadikan sebagai indikator terjadinya gangguan terhadap otak kecil pada pemberian ekstrak methanol biji pare (Momordica carantia L.) dan DMPA. Metode eksperimen digunakan untuk menentukan perbedaan yang terjadi pada tiap kelompok kontrol dan pemberian lama pemberian ekstrak biji pare dan DMPA. Kelompok kontrol terbagi dalam K0, K1, dan K2 dengan waktu berturut-turut 0, 4, dan 8 minggu. Kelompok perlakuan terdiri dari (P0) biji pare 0 minggu secara oral dan DMPA intramuskular (@ 6 jam), (P1) biji pare dan DMPA (@4 minggu), (P2) biji pare dan DMPA (@8 minggu). Masing-masing kelompok terdiri dari 5 mencit sehingga total mencit jantan adalah 30 ekor. Dosis ekstrak metanol biji pare adalah 5mg/10g berat badan mencit yang diberikan secara oral) (Yama et al. 2011). Sedangkan dosis DMPA sebesar 0,175 mg/ekor mencit yang diberikan secara intramuskular (Ilyas 2014). Hasil penelitian menunjukkan tidak adanya perbedaan yang nyata (p>0,05) antara kontrol dan perlakuan pada 0, 4, dan 8 minggu terhadap jumlah sel purkinje cerebellum mencit. Disimpulkan bahwa pemberian ekstrak metanol biji pare dan DMPA aman terhadap perbedaan jumlah cerebellum mencit
