One problem in aquaculture is obtaining brood because many commercially important species are incapable of spontaneous maturation under artificial conditions. Commercial shrimp hatcheries commonly use eyestalk ablation to stimulate gonadal maturation in shrimps. Research has been conducted on the inhibition of reproductive maturation by hormones originating in the eyestalk glands and on other e...

In a study of chromosomal enlargement in neoplasms, it had been observed that metaphasic chromosomes of the cells of 6 long-transferred lines of lymphatic leukemia were usually larger in male host mice than in female (12). This sexual difference suggested an investigation of the effect of sex hormones on chromosome size in leukemic and normal lymphocytes. Experiments along several possible line...

Reptiles were known to serve as paratenic hosts for Centrorhynchus (Acanthocephala: Centrorhynchidae) in Korea, but the infection course in experimental animals was not elucidated yet. In this study, the tiger keelback snakes (Rhabdophis tigrinus) were collected and digested with artificial pepsin solution, and the larvae of Centrorhynchus were recovered from them.

45 female patients with polycystic ovary syndrome took thioctic acid (Thioctacid-HR), 600 mg (n = 25) or high protein diet (n = 20). Fast insulin and glucose stimulus insulin were investigated before and after 3 months taken treatment. The use of thioctic acid, 600 mg is a new effective pathogenetics therapy of polycystic ovary syndrome on influence of hyperinsulinemia, HOMA-IR index and ovary ...

background: diazinon is a widely used organophosphate insecticide which is applied against plant pests. this compound has various side effects because it acts as an acetyl cholinesterase enzyme inhibitor. objective: the aim of present study was to investigate the effects of diazinon on pituitary–gonad axis and ovarian histological changes in rats. materials and methods: in total 50 female wista...

background: phytoestrogens are a group of plants derived compounds with weekly estrogen effect that appear to have protective effects on metabolic and hormonal abnormalities of women with polycystic ovary syndrome (pcos). so the aim of this study was to investigate the effect of soy phytoestrogens on reproductive hormones and lipid profiles in pcos women. methods: in this quasi-randomized trial...
