Selective luminal absorption of L-carnitine from the proximal regions of the rat epididymis. Possible relationships to development of sperm motility
L-carnitine rat epididymis sperm motility microperfusion
2009/2/23
The absorption of L-carnitine from the duct of the proximal regions of the rat epididymis was investigated using a stopped-flow, split-droplet microperfusion technique. L-carnitine was absorbed from...
Protein secretion by the rat epididymis can be selectively modified in vitro by local anesthetics, glucose deprivation, dinitrophenol, ouabain, and ionophores
Protein secretion rat epididymis selectively modified local anesthetics
2009/2/20
Protein secretion by the caput epididymidis has been examined in vitro using radioactive methionine as a precursor for protein synthesis. Newly synthesized and secreted proteins were separated by gel ...
Structural features of cultured epithelial cells from the adult rat epididymis
epididymis epithelium primary culture
2009/2/20
Epithelial cells isolated from the caput epididymidis of adult rats were placed in primary culture and examined daily for ten days for changes in external anatomy, reorganization of cytoskeletal com...
The ability of the rat epididymis to concentrate spermatozoa. Responsiveness to aldosterone
aldosterone epididymal spermatozoa
2009/2/19
Experiments have been performed to determine if aldosterone is involved in the control of water reabsorption from the epididymal lumen in vivo. Micropuncture samples of lumen content were collected ...
Changes in the number, proliferation rates, and bcl-2 protein immunoexpression of epithelial and periductal cells from rat epididymis during postnatal development
Basal cells cell proliferation
2009/2/18
To investigate 1) the correlation between the proliferative activity of epididymal epithelium plus myoid cells and the increase in the number of these cells and 2) the role of the basal epithelial c...
Androgen binding protein secretion and endocytosis by principal cells in the adult rat epididymis and during postnatal development
Androgen binding protein secretion endocytosis principal cells adult rat epididymis
2009/2/18
Androgen binding protein (ABP) has been shown to be secreted by Sertoli cells and to be actively taken up by the efferent ducts and proximal caput epididymidis and, yet, to be present at high concen...
Oxidative stress differentially regulates the expression of gamma-glutamyl transpeptidase mRNAs in the initial segment of the rat epididymis
gamma-glutamyl transpeptidase mRNAs initial segment rat epididymis
2009/2/17
Reactive oxygen species (ROS) have a powerful cytotoxic effect on spermatozoa and have been implicated in spermatozoal dysfunction and male infertility. gamma-Glutamyl transpeptidase (GGT) is esse...
Stability and transcriptional regulation of gamma-glutamyl transpeptidase mRNA expression in the initial segment of the rat epididymis
Stability transcriptional regulation gamma-glutamyl transpeptidase mRNA initial segment rat epididymis
2009/2/17
Gamma-glutamyl transpeptidase (GGT) is an enzyme believed to play a role in the protection of maturing spermatozoa in the epididymis. Our previous studies have shown that four GGT mRNAs (I-IV) trans...
Partial sympathetic denervation of the rat epididymis permits fertilization but inhibits embryo development
Inferior mesenteric ganglion fertility spinal cord injury innervation spermatozoa intrauterine insemination
2009/2/17
The rat cauda epididymidis receives sympathetic innervation from the inferior mesenteric ganglion (IMG). We have previously demonstrated that surgical removal of the IMG and proximal hypogastric ner...
Apical and narrow cells are distinct cell types differing in their structure, distribution, and functions in the adult rat epididymis
Apical and narrow epithelial cells initial segment intermediate zone epididymis rat
2009/2/16
Apical and narrow cells of the initial segment and intermediate zone of the adult rat epididymis were glutaraldehyde fixed and Epon embedded for routine light (LM) and electron (EM) microscopic an...

Androgens development hormonal regulation male
2009/2/16
The enzyme steroid 5 alpha-reductase (EC 1.3.1.22) catalyzes the conversion of testosterone to its more potent form, dihydrotestosterone (DHT), in many androgen-sensitive target tissues. In the ep...
