Effect of Psidium guajava Juice on The Seminiferous Tubules Diameter and Epithelium Thickness in Rattus norvegicus Exposed by Lead Acetate

Lead is one of humans and animals' most common and hazardous heavy metals. This study aimed to investigate the effect of white guava (Psidium guajava) fruit juice on the seminiferous tubule diameter and epithelium thickness in rats (Rattus norvegicus) exposed to lead acetate. The research design was a completely randomized design (CRD). A total of 25 male rats with an average weight of 200 grams were used for the study, divided into 5 treatment groups, each consisting of 5 rats. The treatments were as follows: the control group (C) was given distilled water orally; the T0 group was induced with lead acetate (50 mg/Kg BW) orally; the T1, T2, T3 groups were induced with lead acetate (50 mg/Kg BW) and then given 25%, 50%, and 100% concentration of white guava fruit juice, respectively. All the treatments were conducted for 14 days. The histopathology slides of the testis were made with HE staining, and the seminiferous tubule diameter and epithelium thickness were measured. The data were analyzed using One Way ANOVA and Duncan test (p<0.05). The results showed that the control group (C) which was given distilled water only had a seminiferous tubule diameter and epithelium thickness of 336.24±23.32 µm and 66.46±4.39 µm, respectively. The T0 group which was induced with lead acetate only showed a reduction in the diameter and epithelium thickness of seminiferous tubules (243.38±49.35 µm and 44.08±14.45 µm). The members of the T1, T2 and T3 groups showed positive effects on the diameter (323.49±22.82 µm; 314.41±13.04 µm; 325.04±16.88 µm, respectively) and epithelium thickness (56.36±3.36 µm; 60.50±3.81 µm; 66.744±9.50 µm, respectively). There was no significant difference reported between each group. The administration of guava juice to rats induced with lead acetate can positively affect the diameter and epithelium thickness of seminiferous tubules

Determination of Born Calves' Sex Based on Insemination Time in Dairy Cows

Former researchers found that there are differences of shape, cap size, motility ability, age, electricity and chemical characters between Y and X chromosome bearing sperm. Y sperm moves f aster, has smaller size but shorter life time within f emale reproduction tract. In opposite, X sperm is 3% fatter and has more round shape. Concerning its bigger shape, X sperm moves slower, but has longer life time in f emale reproductive tract. Based on that matter, this research was conducted to find out the sex of born calves depend on insemination time, early to inseminate, best time to inseminate and late to insem.inate. This research used 40 head of cows, divided by four groups; each group consists of 10 head. Control group was inseminated by sexed semen, first, second, third and forth group was inseminated by unsexing semen, respectively on early, the best and late time of insemination. Successfully pregnancy was obtained from the best time insemination, both by sexing and unsexing semen. While born calves sex were not significant different, meant almost the same, from. both semen. Research result showed insemination by both sexing and unsexing semen which was done in early time to inseminate will tend yield female calve

Level of Heat Shock Protein 70 and Cortisol in Bull's Serum Before and After Collecting Semen

Artificial Insemination is a breeding technique by injecting semen into the female genital tract by using Artificial Vagina. The process of collecting semen, bulls can experience of stress which the effect can be affect in reproduction process. This study aims to prove that the increased levels of HSP 70 and cortisol in bull’s serum after collecting semen as an indicator of stress in cattle. Blood serum used for ELISA (Enzyme-Linked Immunosorbent Assay) test using Bovine-HSP 70 Test Kit and Bovine Cortisol Test Kit then the result read by ELISA reader. The result showed that no significant differences. The conclusion from this study was that elevated levels of HSp 70 and cortisol levels were not significant, so it is suggested further research on the increased levels of HSP 70 and cortisol levels to the manufacture of frozen semen for artificial insemination.
