The growth of the ventral and dorsolateral prostate, the coagulating glands and the seminal vesicles in force-fed hypophysectomized castrated adrenalectomized rats injected with cortisone and-or insulin.

ABSTRACT The growth of the ventral and dorsolateral prostate, the coagulating glands and the seminal vesicles was studied in force-fed hypophysectomized castrated adrenalectomized rats following daily injections for fourteen days of protamine zinc insulin or cortisone acetate alone or in combination. Cortisone was given in daily doses of 3 mg and insulin was administered in increasing daily doses of protamine zinc insulin up to 8 IU. Cortisone alone induced slight histological stimulation of the epithelium of the coagulating glands, while no stimulation was demonstrated in the other accessory reproductive organs. After insulin alone the weight of the accessory reproductive organs was slightly increased but no stimulation was demonstrated histologically. Cortisone and insulin given in combination induced distinct signs of stimulation of all the accessory reproductive organs as assesed by histological examination and weight determination of the organs. The results indicate that in the rat the growth stimulating effect of cortisone on the male accessory reproductive organs is markedly decreased or abolished in the absence of the anterior pituitary. Insulin can act synergistically with cortisone in promoting the growth of the accessory reproductive organs through effects which are not dependent on the presence of the adrenal glands or the anterior pituitary.

The male accessory reproductive organs in the striped field mouse

Digital Repository of Scientific Institutes (RCIN) was established and is being developed mainly as an outcome of two projects acquired and jointly accomplished by a group of Polish scientific institutes.

The growth of the ventral prostate, the dorsolateral prostate, the coagulating glands and the seminal vesicles in castrated male rats injected with ACTH and-or insulin.

ABSTRACT The growth of the ventral and the dorsolateral prostate, the coagulating glands, seminal vesicles and levator ani muscle was studied in castrated male rats after fifteen days of daily injections with ACTH or insulin alone, or in combination. ACTH was given in a dose of 8 IU daily. Insulin was administered in increasing daily doses, i. e. regular insulin up to 8 IU and protamine zinc insulin up to 10 IU. After ACTH treatment there were variable histological signs of stimulation of the dorsolateral prostate, while the other accessory reproductive organs showed no response. Regular insulin produced no quantitative or morphological changes in the accessory reproductive organs, and no morphological signs of increased secretion of the adrenal steroids. Administration of ACTH and regular insulin in combination stimulated the growth of all the accessory reproductive organs. Protamine zinc insulin produced prolonged hypoglycaemia and morphological signs of increase secretion of adrenal steroids, thus the adrenals became enlarged and the thymus atrophic. Protamine zinc insulin stimulated growth of all the accessory reproductive organs, a stimulation which was further accentuated after combination with ACTH. Possible mechanisms for the action of insulin on the male accessory reproductive organs are discussed. The varying response of the different parts of the prostate and the seminal vesicles emphasizes the importance of the simultaneous examination of these organs.

Histamine levels in male accessory reproductive organs of the rat.

Histamine levels in rat ventral prostate, seminal vesicle and ductus deferens were determined with a fluorometric procedure which involved chromatographic isolation of histamine. Determination of histamine by the butanol extraction-fluorometric procedure was not feasible because of interference by high levels of spermidine. Castration for 14 days increased the histamine concentration in the ventral prostate and seminal vesicles but had no effect on the total organ histamine content. Testosterone propionate treatment restored the' concentration of histamine to normal levels but also had no effect on total organ content of histamine. Neither castration nor testosterone treatment had any effect on histamine levels in the ductus deferens. The lack of change in the total organ content of histamine after castration or testosterone treatment suggests that the concentration changes resulted from regression or regrowth of cells which do not contain histamine. Intravenous injection of testosterone or estradiol had ...

Effects of testosterone propionate on the seminal vesicles of the rat.

MANN and Lutwak-Mann (1951) have reviewed the literature dealing with the many functional as well as structural changes which are known to occur in the male accessory organs of reproduction in mammals when the source of the testicular androgen, testosterone, is removed. The manner in which this hormone functions or the exact site of the biochemical lesion induced by its absence are unknown. This investigation consists of a biochemical and physiological study of the normal development of one of the accessory organs, the seminal vesicles, of the rat as well as the effects of castration and hormone replacement on this organ of the castrate. methods Male rats of the Holtzman-Rolfsmeyer strain were used throughout this investigation. The animals were maintained in groups of four to eight in individual wire cages and were fed Purina Laboratory Chow with supplements of raw carrots and pork liver.

Some metabolic effects of androgenic substances.

IT was previously shown that the secretion of both fructose and citric acid in the male accessory organs of reproduction is governed by, and responds readily to, the fluctuations in the level of the male sex hormone. This close relationship made it practical to use the estimation of fructose and citric acid, either in semen or in the accessory glands, as a 'chemical indicator test' for the male hormone1'2'3. Recently, in the course of a metabolic study of transplants from accessory glands of the rat, it was found that when small pieces of male glands were dissected from young rats and transplanted subcutaneously into male or female hosts, such transplants grew readily in response to testosterone propionate or normally secreted testis hormone, and when fully developed exhibited a high content of fructose and pitric acid4,5.
