Efek pemberian α-tokoferol terhadap jumlah sel spermatogenik dan sel Leydig pada tikus putih (Rattus norvegicus) yang dipapar 2,3,7,8 Tetrachlorodibenzo-p-dioxin

This research aimed to determine the effect of α-tocopherol on the count of spermatogenic and Leydig cells in rats (Rattus norvegicus) exposed to 2,3,7,8 tetrachlorodibenzo-p-dioxin (dioxin). Dioxin is an endocrine-disrupting agent that adversely affects reproductive health, while α-tocopherol maintains fertility. This research used 25 rats aged 10-12 weeks weighing 150-200 grams. Rats were divided into five groups (K, P0, P1, P2 and P3). The K (control group) was administered with corn oil 1 ml/day. P0 was exposed to 700 ng/kg/day dioxin. P1, P2 and P3 was exposed to dioxin at a dose of 700 ng/kg/day and administered with α-tocopherol at a dose of 77, 140 and 259 mg/kg/day respectively. Dioxin exposure, corn oil and α-tocopherol administration were conducted orally for 20 days. On day-21, all rats were sacrificed for histological slides preparation of testicles with hematoxylin-eosin staining. Data were analyzed with analysis of variance and continued with the Duncan test. The results indicated that exposure to dioxin caused a decrease in the number of spermatogenic and Leydig cells. The administration of α-tocopherol at a dose of 140 mg/kg/day eliminated the effect of reducing the number of spermatogenic and Leydig cells caused by exposure to dioxin. The conclusion was the administration of α-tocopherol at 140 mg/kg/day was effective in maintaining the number of spermatogenic and Leydig cells in rats (Rattus norvegicus) exposed to 2,3,7,8 tetrachlorodibenzo-p-dioxin.

Pengaruh pemberian ekstrak daun kelor (Moringa oleifera Lam.) terhadap motilitas dan viabilitas spermatozoa tikus (Rattus norvegicus) dengan paparan panas

This study aimed to determine the effect of Moringa (Moringa oleifera Lam.) leaf extract on the viability and motility of spermatozoa of rats (Rattus norvegicus) exposed to heat (40 ºC). A total of 25 rats aged 2.5 months and weighed 200 grams were randomly divided into five groups. Rats in K (–) group were not exposed to heat and without Moringa leaf extract administration. Rats in K (+) group were exposed to heat (40 ºC) for 1 hour daily without Moringa leaf extract administration. Meanwhile, rats in P1, P2, and P3 groups were administrated with Moringa leaf extract 100, 200, and 400 mg/kg BW/day, then exposed to 40 ºC 1 hour daily for 14 days. The results showed that exposure to 40 °C one hour per day for 14 days in K (+) group caused a decrease (p <0.05) on viability and motility of rat spermatozoa compared to those of the K (–) group. The administration of Moringa leaf extract (P1, P2, and P3 groups) was followed by an increase (p <0.05) in viability and motility of rat spermatozoa compared to the K (+) group. Viability and motility of rat spermatozoa in the P3 group (given Moringa leaf extract 400 mg/kg BW/day and exposed to 40 ºC 1 hour daily for 14 days) were not significantly different (p >0.05) compared to the viability and motility of rat spermatozoa in K (–) group. It could be concluded that administration of Moringa leaf extract 400 mg/kg BW/day can maintain the viability and motility of spermatozoa in white rats exposed to heat.

Pengaruh urea dalam media maturasi in vitro terhadap tingkat maturasi oosit sapi

This study was aimed to determine the effect of urea in maturation medium on in vitro oocyte maturation rate. The medium used was TCM-199 added with Hepes, NaHCO3, Kanamycin 0.15 IU/mL, PMSG, 0.15 IU/mL hCG, and 10% FBS. Cumulus oocyte complexes (COCs) of cows derived from follicle aspiration were divided into three groups. In control group (P0), the COCs were matured in vitro in a maturation medium without urea addition, meanwhile in the P1 and P2 groups, the medium was added with urea 20 and 40 mg/dL, respectively. Each petri dish contained three drops of maturation medium (300 µl/drops) according to the groups. Microdrops were coated with mineral oil and then incubated in a 5% CO2 incubator, at 39 ˚C with maximum humidity. Aceto-orcein staining was conducted to evaluate the maturation of oocytes based on the achievement of metaphase II phase that is indicated by the presence of metaphase plate and/or first polar body. The result showed that the oocyte maturation rates of P0, P1, and P2 were 51.25, 52.43 (p >0.05), and 46.88 % (p <0.05) respectively. It could be concluded that the presence of urea at 40 mg/dL in maturation medium reduced the percentage of bovine oocyte maturation in vitro.

Serum Progesterone profile of pregnant Ettawa crossbred does at day-0, -21, -42, -63 and -84

This study aimed to determine the progesterone concentrations of Ettawa crossbred does at day-0, -21, -42, -63, and -84 after mating. Five Ettawa crossbred does were injected with PGF2α twice with an interval of 11 days for estrous synchronization followed by natural mating on day-3 after the second PGF2α injection. Blood was collected through the jugular vein for the measurement of serum progesterone concentrations using ELISA, whereas pregnancy was diagnosed at 90 days after mating by abdominal palpation. The results showed that all does were on estrus onthethird day after the second PGF2α, three of them diagnosed to be pregnant following mating. The progesterone concentration at day-0 was 1.52 ± 0.33 ng/mL, increased (p <0.05) to 7.08 ± 1.02 and 5.50 ± 2.82 ng/mL at day-21 and day-42, and increased (p <0.05) again to 12.01 ± 5.30 and 12.04 ± 0.30 ng/mL at day 63 and day 84, respectively. There was no significant difference in progesterone concentrations between day 21 and day 42 and between day 63 and day 84. It could be concluded that there was a biphasic increase of progesterone concentrations of the pregnant Ettawa crossbred does, i.e. from day-0 to day-21/day-42 and from day-21/day-42 to day-63/day-84.

This case study aims to determine the effect of a combination of prostaglandin F2α (PGF2α) with Gonadotropin (PG-600), and human chorionic gonadotropin (hCG) on the estrus and pregnancy rates in Holstein Friesian (HF) cows with persistent corpus luteum (PCL). A total of 15 Holstein Friesian (HF) dairy cows aged 3-5 years with body condition score (BCS) 5-7 (scale 1-9) diagnosed with PCL, were injected with 7.5 mg PGF2α intra-vulvar submucosa. Cows were then divided into three treatment groups. Group P0 was not given the combination treatment, while P1 group was injected with a combination of 300 IU PG-600 and 150 IU hCG, meanwhile P2 group was was injected with a combination of 300 IU PG-600 and 300 IU hCG intra-muscularly. The PGF2α and PG-600 injections were carried out on the same day PCL was diagnosed. Meanwhile, the injection of hCG was carried out at the same time as the AI. The Pregnancy examination was performed 90 days after AI through rectal palpation. The results showed that all treated cows were estrus observed with the fastest onset of estrus was the P2 group, that was significantly different (p <0.05) compared to the P0 and P1 groups. All treated cows were diagnosed as pregnant. It can be concluded that the administration of PGF2α or its combination with gonadotropins in HF cows with PCL could result in 100% estrus and pregnancy rates.

Pengaruh ekstrak daun binahong (Anredera cordifolia ) terhadap pemulihan siklus estrus mencit (Mus musculus)

This study aimed to determine the effect of binahong (Anredera cordifolia) leaf extract on the recovery of the estrous cycle of mice (Mus musculus) which has been induced for the extension of the estrous cycle using angsana (Pterocarpus indicus) bark extract. In this study vaginal smear was performed daily at 10.00 WIB to determine the phase of the estrous cycle for 26 days. Mice were divided into 5 groups, each with 6 replicates. The treatments were T1 (positive control), T2 (negative control), T3 (0.8 mg/head/day), T4 (2.4 mg/head/day) and T5 (4 mg/head/day). The data obtained were processed using Analysis of Variance (ANOVA) and followed by the Duncan's New Multiple Range Test (DNMRT) at a 95% level of significance. The results showed that the angsana (Pterocarpus indicus) bark extract adminsitration (T2) lengthen (p <0.05) the estrous cycle of mice compared to those of normal mice (T1). The administration of binahong (Anredera cordifolia) leaf extract on T3 and T4 groups mice were followed by shorter (p <0.05) estrous cycle than those of T2, and it were not significantly different (p >0.05) compared to T1 group. However, the higher dose of binahong (Anredera cordifolia) leaf extract (T5) revealed the length of estrous cycle was not significantly different (p >0.05) compared to T2 group. It can be concluded that the administration of binahong leaf extract was able to recover the normal estrous cycle of mice.
