Prostaglandin dehydrogenase activity of rat and rabbit testicular tissues and accessory glands before and after castration
Prostaglandin dehydrogenase activity rat rabbit testicular tissues
2009/2/20
Rat reproductive tissues contained both 15-hydroxy-prostaglandin dehydrogenase (PGDH) and delta 13-reductase activities, while rabbit tissues exhibited only PGDH activity. In the rat, delta 13-reduc...
Localization of tubulin and microtubules of in vivo fertilized rabbit oocytes
fertilization microtubules acrosome acrosin
2009/2/20
The presence of tubulin throughout what appears to be sperm penetration tunnels of in vivo fertilized rabbit oocytes was demonstrated by both immunofluorescence and transmission electron microscopy,...
Specific binding of the glycosaminoglycan 3H-heparin to bull, monkey, and rabbit spermatozoa in vitro
sperm acrosome reaction glycosaminoglycans
2009/2/20
In Vitro binding and some binding parameters of the glycosaminoglycan heparin to viable epididymal or ejaculated bull spermatozoa, ejaculated rabbit spermatozoa, and frozen-thawed rhesus monkey sper...
In Vitro Sperm Capacitation and In Vitro Fertilization with Normal Development in the Rabbit
sperm capacitation in vitro fertilization embryo culture embryo transfer spermatozoa oocytes rabbit
2009/2/19
The objective was to obtain in vitro sperm capacitation and fertilization to approximate the normal in vivo processes. Rabbit oocytes from follicles, ovarian surfaces, and oviducts were fertilized...
Vasocystostomy in the Rabbit: Surgical Technique and Sperm Outflow
vasocystostomy surgery rabbit sperm urine
2009/2/19
The surgical technique employed for construction of bilateral vas-to-bladder fistulae (vasocystostomy) in the male rabbit is described. The method of collection and results of examination of sperm...
A Continuous Flow Method for Organ Culture of Rabbit Epididymis：Morphology, Amino Acid Utilization, Glucose Uptake, RNA, and Protein Synthesis
epididymis organ culture glucose uptake amino acid utilization
2009/2/18
A modified perfusion system was developed to maintain an unconvoluted tubule from the corpus epididymidis of the rabbit in organ culture. The epididymal explant is submerged in a continuous flow of ...
Effect of Hypoxia on Spontaneous Contractions of the Adult Rabbit Isolated Testicular Capsule and Duodenum
testis capsule hypoxia sperm transport testis capsule contractions
2009/2/18
Spontaneous contractions of the adult rabbit isolated testicular capsule have been found to be adversely affected by short exposures to hypoxia. The data of the present study suggest that acute expo...
Involvement of endothelial nitric oxide synthase in the impaired endothelium-dependent relaxation of cavernous smooth muscle in hypercholesterolemic rabbit
Hypercholesterolemia cavernous smooth muscle
2009/2/18
The present study was designed to evaluate whether functional impairment and/or protein expression of constitutive nitric oxide synthase (cNOS; endothelial NOS [eNOS] and neuronal NOS[nNOS]) was i...
Rabbit spermatozoa：a model system for studying ATP homeostasis and motility
Creatine kinase adenylate kinase adenylic metabolism
2009/2/18
This paper studies the adenosine triphosphate (ATP) homeostasis and the motility parameters of rabbit spermatozoa. Rabbit sperm, collected by artificial vagina, were studied in various buffer system...
Evidence for a role of intracellular-calcium release in nitric oxide-stimulated relaxation of the rabbit corpus cavernosum
Calcium erection thapsigargin ryanodine
2009/2/17
Erection is mediated by relaxation of the smooth muscle elements within the sinusoids of the corpus cavernosum. Although cavernosal relaxation can be mediated by a variety of mechanisms including pu...
Media and dilution procedures tested to minimize handling effects on human, rabbit, and bull sperm for computer-assisted sperm analysis（CASA）
CASA holding time hyperactivation TALP PBS
2009/2/16
Proper handling of semen prior to computer-assisted sperm analysis (CASA) is critical if the analysis is to be representative of the fresh sample. The effects of diluting medium or dilution and ho...

Erection adenosine relaxation penis impotence
2009/2/13
In the present study the effect of adenosine and adenosine analogues on rabbit isolated cavernosal smooth muscle has been evaluated in comparison with the effect of acetylcholine and electrical fi...
Cloning and partial sequence of the rabbit androgen receptor：expression in fetal urogenital tissues
Development mesonephros androgen receptor urogenital sinus rabbit prostate
2009/2/13
Genetic studies indicate that the actions of testosterone and dihydrotestosterone are mediated by a single androgen receptor (AR). The basis for the differential effects of these hormones during d...
