Uptake and release of ascorbic acid by rat Leydig cells in vitro
ascorbic acid rat Leydig cells
2009/2/23
The mechanism by which ascorbic acid is transported into rat Leydig cells in vitro was investigated. Transport of [14C]ascorbic acid was temperature-dependent and inhibited in the absence of sodium ...
Inhibition of ornithine decarboxylase activity by follicle stimulating hormone in primary culture of rat Sertoli cells
ornithine decarboxylase follicle stimulating
2009/2/23
The effect of follicle stimulating hormone on the activity of ornithine decarboxylase (ODC) was determined in primary culture of rat Sertoli cells. Three different FSH preparations (NIH oFSH-S-15, S...
Computerized videomicrographic analysis of rat sperm motility
Computerized videomicrographic analysis rat sperm motility
2009/2/23
Quantitative methods for the determination of the concentration, percent motility and swimming speed of human and animal spermatozoa can assist in the objective analysis of sperm and semen quality. ...
Suppression of steroid receptor-chromatin interaction by inhibitors present in ammonium sulfate-fractionated rat testicular androgen receptor preparations
steroid receptor-chromatin interaction inhibitors present ammonium sulfate-fractionated rat
2009/2/23
Tritiated androgen receptor complex was partially purified by ammonium sulfate precipitation at 15 to 37% saturation from rat testicular or prostatic cytosols. A greater amount of prostatic tritiate...
Testicular hemodynamic changes after the surgical creation of a varicocele in the rat. Intravital microscopic observations
Testicular hemodynamic changes surgical creation varicocele rat
2009/2/23
The present study investigated the effect of a surgically induced varicocele on the dynamics of testicular blood flow. The surface vasculature of the normal and the varicocele-affected testis was ex...
Modification of the rat sperm flagellar plasma membrane during maturation in the epididymis
Modification rat sperm flagellar plasma membrane maturation epididymis
2009/2/23
Previously, we demonstrated that surface radiolabeling of rat epididymal spermatozoa by lactoperoxidase-catalyzed iodination reveals a major component with an apparent molecular weight of 26,000 to ...
Corticosterone-induced changes in serum hormone profiles and the lipid composition of the caput and cauda epididymidis were studied. The analysis was conducted in both unwashed and washed (free from...
Characterization of beta-adrenergic receptors in dispersed rat testicular interstitial cells
rat testis Leydig cell $-adrenergic receptor
2009/2/23
Recent studies have shown that beta-adrenergic agents stimulate steroidogenesis and cyclic AMP formation in mouse Leydig cells in culture. To obtain information about the possible presence and the c...
Antimitotic drugs（cyclophosphamide and vinblastine）in the male rat. Deaths and behavioral abnormalities in the offspring
cyclophosphamide vinblastine male rat spermatogonia mutation offspring
2009/2/23
The spermatogenesis and the offspring of male rats treated either with cyclophosphamide alone, or with both cyclophosphamide and vinblastine were investigated. The offspring were evaluated for the...
Effects of diazacholesterol dihydrochloride（SC-12937）, an avian antifertility agent, on rat testis
testis germ cell Sertoli cell antifertility agent SC-12937 rat
2009/2/23
The present study was undertaken to evaluate the effectiveness of an avian chemosterilant, 20, 25-diazacholesterol dihydrochloride (SC-12937), on the rat testis. Adult male rats were injected intrap...
Repair of experimental varicoceles in the rat. Long-term effects on testicular blood flow and temperature and cauda epididymidal sperm concentration and motility
varicocele varicocele repair rat testis
2009/2/23
The effects of varicocele and varicocele repair on testicular blood flow, temperature, sperm counts, and sperm motility were assessed in adult male rats. The duration of the experimental varicocele ...
The effect of selective destruction and regeneration of rat Leydig cells on the intratesticular distribution of testosterone and morphology of the seminiferous epithelium
selective destruction regeneration rat Leydig cells intratesticular distribution
2009/2/23
This study was designed to explore the relationship between the intratesticular distribution of testosterone and spermatogenesis by completely destroying the Leydig cells of mature male rats with in...
The heterogeneity of rat androgen binding protein（rABP）in the vascular compartment differs from that in the testicular tubular lumen. Further evidence for bidirectional secretion of rABP
rat ABP ABP heterogeneity
