This study was conducted to evaluate the effect of Sertraline administration in pregnancy on liver function of male neonates of rats. Twenty-five pregnant female Wistar rats were divided into 4 groups of 5. The control group did not receive any drug treatments, but experimental (Exp) groups 1, 2 and 3 received 5, 10 and 20 mg/kg Sertraline as gavage throughout the pregnancy, respectively. Twenty-two days after birth, male rats were divided into 4 groups of 10 based on the previous division and after weighing, by taking blood directly from the heart, serum levels of Alanine transaminase (Alt), Aspartate transaminase (AST), Alkaline phosphatase (Alp), Albumin (Alb), Total protein (TP), and Bilirubin (Bili) were measured and the liver tissue was also analyzed histopathologically after weighing. In Exp groups, a significant decrease in body weight, TP and Alb serum levels were observed compared to the control group (p<0.05). In Exp group 3, a significant decrease in liver weight was observed compared to the control group (p˂0.05). In Exp groups 2 and 3, a significant increase in serum levels of Alp, Alt and Bili in was observed compared to the control group (p˂0.05). A significant increase in AST serum level was observed in Exp groups compared to the control group (p˂0.05). Liver tissue destruction was observed in all 3 Exp groups. The administration of Sertraline in pregnant female rats causes liver damage and increases liver enzymes and blood biochemical parameters in their male offspring.","PeriodicalId":17806,"journal":{"name":"Jurnal Ilmu Ternak dan Veteriner","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46841750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polled are Balinese cattle whose horns do not grow naturally, but have the same characteristics as those with horns. However, there are indications that polled have a lower libido. The purpose of this study was to determine the characteristics of libido and testosterone concentration after gonadotrophin releasing hormone (GnRH) injection. In this study each of 7 male polled and horned Bali cattle aged 3.5-6 years were used. Libido characteristics were observed by recording the first time the male fondled the teaser until ejaculation, while the testosterone concentration was measured using blood plasma taken on day 0 or before injection, day 7th, and day 14th after GnRH injection. Testosterone analysis used enzyme linked immunosorbent assay (ELISA) method. The results showed that the libido of polled was not different (P>0.05) compared to that of the horned on the 0, 7th and 14th days after GnRH injection. However, in polled on the 7th day after GnRH injection, it was significantly lower than on day 0 and 14, but on day 0 it was not different with day 14. Testosterone concentration on day 7 after injection of GnRH was not different (P>0.05) compared to day 0 both in polled and horned bulls, but on day 14 after injection was significantly higher (P<0.05) in horned than polled. In conclusion, polled and horned Bali bulls had high libido with a score of +1, but on the 7th day after GnRH injection, polled had lower libido than horns.

Fluctuating asymmetry (FA) is a random deviation from perfect bilateral symmetry. FA is often used to measure developmental stability in individuals and can be used as a marker for the impact of environmental and genetic stress. This study aims to investigate the pattern of developmental instability in Bali cattle as caused by environmental stress at various altitudes using the FA index. FA indexes in this study were used to compare asymmetrical physical traits of Bali cattle in Sembalun high altitude and Serading low altitude. Sixty-five Bali cattle were used in this study reared at different altitudes, namely Serading, Sumbawa Island (50 m above sea level), and Sembalun, Lombok Island (1,186 m above sea level). The physical traits of Bali cattle measured were horn circumference (horn), a distance of hip to spine bone (pelvic), metatarsal circumference (metatarsal), and metacarpal circumference (metacarpal). The FA1 and FA5 indexes showed significant metacarpal differences between Bali cattle reared at Sembalun and Serading population (P<0.05). FA11 multiple trait index as a composite of all traits revealed a significant difference as well. (P<001).

The purpose of this study was to discover the polymorphism of the AvBD2 gene in IPB-D1 chickens. PCR and direct-DNA sequencing methods were used to identify the diversity of intron 1, exon 2, and intron 2 AvDB2 genes in 47 chickens.

Twenty-five mice were infected intraperitoneally with each isolate and 20 were treated with the 4 drugs (5 mice/drug) while 5 infected mice and 7 uninfected mice served as infected-untreated and uninfected controls, respectively. Treatment was carried out 24 hours post-infection and parasitemia was monitored for 35 days. Mice infected with Philippine isolates significantly died earlier (5-11 days) than those infected with the Indonesian isolate (14-16 days). The prepatent period for Philippine isolates (3-8 days) was significantly shorter than the Indonesian strain (11-13 days). Trypanosomes were not observed in the blood of mice infected with any of the Philippine isolates when treated with quinapyramine sulphate/chloride, melarsomine dihydrochloride or suramin.
