Nature of alpha subunit secretion in men：circadian rhythms, pulsatile release and secretory profiles
alpha subunit secretion men circadian rhythms pulsatile release secretory profiles
2009/2/23
Alpha subunit complements LH as a marker of the activity of the hypothalamic GnRH pulse generator. To characterize episodes of alpha subunit release and to determine if a circadian pattern of alpha ...
Kinetics of secretion of luteinizing hormone subunits and free alpha, and effects of gonadotropin releasing hormone
luteinizing hormone subunits gonadotropin releasing hormone
2009/2/23
While GnRH is known to stimulate release of pituitary gonadotropins, its acute effects on the kinetics of secretion of the various hormones and subunits are not well characterized. Pulse-chase exp...
Chronic ethanol ingestion during puberty alters the transient increase in testicular 5 alpha-reductase in the Swiss-Webster mouse
transient increase testicular 5 alpha-reductase Swiss-Webster mouse
2009/2/23
Previous experiments with inbred mice showed that chronic ethanol treatment delays male pubertal development. An initial event in sexual maturation in the rat is a transient increase in 5 alpha-re...
Alpha-glucosidase as a specific epididymal enzyme marker. Its validity for the etiologic diagnosis of azoospermia
azoospermia epididymal marker aglucosidase carnitine obstructive pathology
2009/2/23
Azoospermic semen was obtained from 39 vasectomized men and 93 patients consulting for infertility. The latter underwent bioclinical investigations including measurement of plasma FSH and testicular...
Receptor-mediated endocytosis of alpha 2-macroglobulin by principal cells in the proximal caput epididymidis in vivo
alpha 2-macroglobulin principal cells proximal caput epididymidis
2009/2/20
Micropuncture techniques were used to study receptor-mediated endocytosis of alpha 2-macroglobulin bound to colloidal gold (alpha 2M-gold) by principal cells in the proximal caput epididymidis of co...
Similar biochemical properties of human seminal plasma and epididymal alpha-1,4-glucosidase
1-4 glucosidase seminal plasma epididymis
2009/2/20
We have studied some characteristics of alpha-1,4-glucosidases in human male reproductive organs in order to obtain information on the origin of the enzyme in seminal plasma. Acid and neutral enzyme...

The male antifertility agents alpha chlorohydrin, 5-thio-D-glucose, and 6-chloro-6-deoxy-D-glucose interfere with sugar transport across the epithelium of the rat caput epididymidis
rat epididymis sugar transport antifertility
2009/2/19
The effects of the male antifertility agents alpha-chlorohydrin, 5-thio-D-glucose, and 6-chloro-6-deoxy-D-glucose on sugar transport (3H-3-O-methyl-D-glucose and 3H-2-deoxy-D-glucose) across the r...
