Survivorship of the immature stage of Anopheles culicifacies in Damar District were studied through sampling larval and pupal stages from stream bed pools and rice fields during May and August 1993. T...
Evaluation of immunosuppressive tumor-escape mechanisms in tumor-bearing hosts is of great importance for the development of an efficient tumor immunotherapy. We document here the functional charact...
The development of the blood-epididymis barrier in immature rats (8, 11, 14, 18, and 21 days old) was examined with an electron microscope using lanthanum nitrate as an electron dense tracer. A grad...
The influence of germ cells (greater than 85% pachytene spermatocytes) on vectorial secretion of androgen binding protein (ABP) and transferrin by immature rat Sertoli cells was investigated using t...
Acetylcholine inhibits FSH-induced cAMP accumulation in cultured Sertoli cells from immature hamsters. This action of acetylcholine is mimicked by muscarinic cholinergic agonists with a rank order o...
Cryptorchid or hypophysectomized rats were used as models to examine the possible relationships between germ cell development and gonadotropins in the agerelated decline in the responsiveness of t...
Effects of administering low doses of GnRH (30 ng/100 g body weight) at various frequencies on the pituitary-testicular axis were investigated. During a 6-hour treatment period, GnRH was administe...
Exposure of immature male rats to 5% (w/v) ethanol as the sole drinking fluid from weaning age (21 days of age) resulted in a delay in balanopreputial separation (41.3 ± 1.4 days versus 37.6 ± 2.0 d...
A method is described for the dispersion, isolation, and partial characterization of epithelial and stromal tissue cells from the rat ventral prostate. Viable epithelial and stromal cells have bee...
Co-incubation with a potent LHRH agonist, D-Ala6-Des-Gly10-Pro9-NHEt-LHRH (Wy-18,481), did not affect testosterone or progesterone production by adult intact rat testes in vitro. Prior administrat...
The in vitro response of Sertoli cells isolated from adult rat testes to testosterone (T) and follicle-stimulating hormone (FSH) treatment was investigated. Sertoli cells from >70-day-old Sprague-...
The functional influence of cell proteoglycan (PG) undersulfation on estradiol synthesis by immature rat Sertoli cell cultures was investigated by using sodium chlorate, an inhibitor of the active s...
The influences of follicle-stimulating hormone (FSH), gonadal steroids, and culture time were studied in relation to inhibin B production by Sertoli cells of immature rats cultured in vitro. Serto...
The induction of neonatal hypothyroidism from day 1 to day 25 postpartum using 6-propyl-2-thiouracil (PTU) resulted in a 45% and 77% reduction of testis weight on days 20 and 30, respectively, and a...
The objective of this study was to determine the effects of pituitary hormones (luteinizing hormone [LH], follicle-stimulating hormone [FSH], growth hormone [GH], and prolactin [PRL]) on interstit...
