The effects of oestradiol and the oestrogen receptor antagonist ICI 182,780 were investigated on the DTH index, serum IgG and IgM levels and spleen weight in female BALB/c and MRLL/MP-lpr/lpr mice. At six weeks, the mice were ovariectomised, and one

The cause of the onset of puberty in the rat or any other mammalian species is unknown. According to one theory, puberty is initiated through switching of the brain "gonadostat." It is hypothesized here that puberty in the rat is the consequence of t

Differences in the thymus of young and old male CSE Wistar rats were examined by use of routine histological stains on paraffin-embedded sections. There was a highly significant loss of thymic weight and disruption of architecture with age. Both surg

Cytosols were incubated from the hypothalamus and mid-brain and from the uterus, and incubated with [3H]progesterone alone or in the presence of excess radioinert steroid to reveal saturable binding sites. Bound and free hormone were separated by gel

Cytosolic androgen receptors from neocortex, hypothalamus and anterior pituitary and ventral prostate glands were analysed by miniature isoelectric focusing and sucrose density-gradient centrifugation before and after precipitation of [3H]dihydrotest

Total oestradiol concentrations in the serum of young female rats were high and decreased after about 21 days of age. High affinity serum oestradiol-binding components (EBP), however, fell steadily from 5 to 23 days of age while the unbound oestradio

The effects of several steroids on the regenerating thymus in ageing male rats have been studied. Rats aged from 12 to 15 months were orchidectomized and 7 days later implanted s.c. with silicone elastomer tubing containing 25 mg testosterone, 5α-di

Available high-affinity binding sites for 5α-dihydrotestosterone (DHT) were measured in cytosols obtained from the amygdala, hypothalamus, anterior pituitary gland and ventral prostate gland of 12-week-old rats at various times after orchidectomy, a

The hypothesis was tested that the inhibitory action of testosterone on thymus growth is mediated by its metabolism to oestradiol. Immature female rats were given s.c. implants of silicone elastomer tubing containing 5 or 20 mg testosterone alone, or
