A Model for Involving Youth in Health Planning：HIV Prevention in Pennsylvania
Health Planning Pennsylvania HIV Prevention
2009/9/17
Despite major advances in the treatment of HIV and AIDS, continued transmission of HIV remains a major public health problem. Declines in AIDS incidence during the 1990s were not accompanied by compar...
Transplantation of newborn rat testis under the kidney capsule of adult host as a model to study the structure and function of Leydig cells
newborn rat testis kidney capsule adult host Leydig cells
2009/2/23
Newborn rat testis was transplanted under the kidney capsule of adult castrated and uncastrated male rats to develop and characterize a model system for studies on Leydig cell development. Two weeks...
Control of metastases in the Nb rat prostatic adenocarcinoma model
metastases Nb rat prostatic adenocarcinoma model
2009/2/20
Chemotherapeutic agents, as well as acetyl-salicylic acid, heparin, and indocin, were evaluated in regard to their effect on the rate of metastasis in the androgen-insensitive Noble rat prostate a...
Tubular patency is the primary concern in the evaluation of procedures for epididymovasostomy. The epididymal lumen easily becomes occluded or obstructed, with the resulting recurrence of azoospermi...
Animal model of isolated gonadotropin deficiency. II. Morphologic responses to LHRH immunoneutralization
hypogonadotropic-hypogonadism LHRH dog immunohypophysectomy testis prostate excurrent
2009/2/19
Morphologic changes in the male reproductive system of mongrel dogs immunized against LHRH were quantitated using linear measurements and morphometric techniques at the light-microscopic level. Two ...
Animal model of isolated gonadotropin deficiency. I. Hormonal responses to LHRH immunoneutralization
hypogonadotropic-hypogonadism luteinizing hormone releasing hormone pituitary serum LH
2009/2/19
Five intact male mongrel dogs, characterized by an episodic secretory pattern of LH and normal serum testosterone concentrations, were actively immunized against LHRH by subcutaneous injections of 2...
Pure Sertoli Cell Cultures：A New Model for the Study of Somatic-Germ Cell Interactions
cell cultures Sertoli cell germ cell
2009/2/19
A new technique involving a brief hypotonic treatment was developed for obtaining pure rat Sertoli cell cultures. This method for the selective removal of the germ cells present in Sertoli cell enri...
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...
Spermatogenesis in early and chronic phases of experimental spinal cord injury in the rodent model
Flow cytometry sperm chromatin sperm chromatin
2009/2/18
A rodent model was used to study the degree and dynamics of potential spermatogenic alterations during both acute and chronic phases after experimental spinal cord injury (SCI). Sexually mature Spra...
Comparison of responses to adrenomedullin and calcitonin gene-related peptide in the feline erection model
ADM CGRP penile erection nitric oxide KATp channe
2009/2/17
The purpose of the present study was to investigate the effects of intracavernosal injections of adrenomedullin (ADM) and calcitonin gene-related peptide (CGRP), two structurally similar peptides,...
Prevention of seminiferous tubular atrophy in a naturally cryptorchid rat model by early surgical intervention
Cryptorchidism orchiopexy testis descent
2009/2/17
In an attempt to determine whether the seminiferous tubular atrophy of the cryptorchid testis is preventable by early surgical correction of the cryptorchid state, aberrantly developed gubernacula d...
In vivo model for chronic direct intratesticular drug administration
Male infertility testicular toxicity miniosmotic pumps
2009/2/12
The efficacy and toxicity of a new method for chronic direct intratesticular drug infusion were assessed in a rat model. To this end, luteinizing hormone (LH) or buffer was infused via miniosmotic...
