Objective: This study was conducted to investigate the effects of estradiol benzoate injection to intact and castrated male rabbits on LH, FSH, testosterone and prostate tissue. Materials and methods: A total of 72 mature male rabbits were used in this study. The rabbits were randomly divided into two groups (36 intact and 36 castrated) and each group was further divided into four sub-groups. T...
We determined the inhibitory effect of dietary atorvastatin, dietary celecoxib and voluntary running wheel exercise (RW) alone or in combination on the formation and growth of androgen-independent LNCaP tumors in castrated SCID mice. Male SCID mice were injected subcutaneously with androgen-dependent prostate cancer LNCaP cells. When the tumors reached a moderate size, the mice were surgically ...
Hormonal dependence of adrenal cortical tumors of CE and BALB/c mice in serial intraocular transfer.
MATERIALS AND METHODS The adrenal cortical tumors used, all arising in castrated males and, if already transplanted, being carried in castrated males (18), were: CE 1, the original neoplasm in a CE mouse; BALE 5880/1,1 a first-generation subcutaneous transplant in a BALB/c; B ALB 5880/2, a second-generation sub cutaneous transplant of the same tumor in a BALB/c; and CE 366/2, a second-generatio...
Two volatile constituents of male mouse urine, 2-(sec-butyl)-4,5-dihydrothiazole and dehydro-exo-brevicomin, were synthesized and tested for their ability to induce estrous cycle in female mice (the Whitten effect). The suppression of ovarian cycling activity that resulted from grouping the females was abolished by exposure to normal male urine. The synthetic compounds, when added together in a...
Although testosterone administration elicits well-documented anabolic effects on skeletal muscle mass, the enhancement of muscle regeneration after injury has not been widely examined. The purpose of this study was to determine whether anabolic steroid administration improves skeletal muscle regeneration from bupivacaine-induced injury. Male C57BL/6 mice were castrated 2 wk before muscle injury...
Sex differences, laterality, and hormonal regulation of androgen receptor (AR) immunoreactivity in rat hippocampal CA1 pyramidal cells were examined using the PG21 antibody. Adult male rats were either castrated or sham-operated at least 2 weeks prior to sacrifice. Gonadally intact females were sacrificed on the day of proestrus. Animals received an injection of either testosterone propionate (...
Recent reports have shown that stressful situations may affect the production of unconjugated pterins (neopterin and biopterin). The aim of the study was to investigate the effect of castration on neopterin and biopterin plasma concentrations in piglets, using 2 groups of 12 piglets allocated to castrated and uncastrated (control) groups. Pterin concentrations were determined by HPLC with fluor...
