Oestrogens, Progestins and Combinations
'Steroid hormones are essential for the growth, differentiation and function of many tissues in both animaIs and humans. It has been established by animal experimentation that modification of the hormonal environment by surgical removal of endocrine glands, by pregnancy or by exogenous administration of steroids can increase or decrease the spontaneous occurrence of tumours or the induction of ...
متن کاملOestrogens and the skin.
Oestrogen loss at the menopause has a profound influence on skin. Oestrogen treatment in post-menopausal women has repeatedly been shown to increase collagen content, dermal thickness and elasticity. Data on the effect of oestrogen on skin water content are also promising. Further, physiological studies on oestrogen and wound healing suggest that hormone replacement therapy (HRT) may play a ben...
متن کاملOestrogens and spermatogenesis.
The role of oestrogens in male reproductive tract physiology has for a long time been a subject of debate. The testis produces significant amounts of oestrogenic hormones, via aromatase, and oestrogen receptors (ERs)alpha (ESR1) and ERbeta (ESR2) are selectively expressed in cells of the testis as well as the epididymal epithelium, depending upon species. This review summarizes the current know...
متن کاملOestrogens and Mammary Carcinogenesis
There is a large and compelling body of epidemiological and experimental evidence that oestrogens are the fuel behind the aetiology of breast cancer. The carcinogenic effects of oestrogen are postulated to be mediated by: the stimulation of cellular proliferation through their receptor-mediated hormonal activity. Other mechanisms include; direct genotoxic effects by increasing mutation rates th...
متن کاملHost Resistance and Hospital Infection
j Uch has been learned about the behaviour of the microbes that cause Section in hospitals and this epidemiological knowledge has helped to reduce Joss-infection by organisms from outside the patient. Thus, for example, ^vances have been made in preventing airborne infection in operating eatres and in excluding extraneous bacteria from surgical wounds, from abies' skin, and from the urinary tra...
