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 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 ...
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...
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 ...
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 (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...
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...
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...
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 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...
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...
The mammalian epididymis is the site where spermatozoa are matured and then stored. Though many studies have described epididymal functions and their regulation, little is known about how aging af...
The distribution of insulin-like growth factor I (IGF-I) was studied by immunohistochemistry during postnatal development of the rat epididymis. At 2 weeks the immunoreactivity was mainly located al...
The authors describe the occurrence of high levels of S-adenosyl-L-methionine decarboxylase (SAMDC) activity in the rat epididymis, and its ontogeny and androgenic control. As early as 15 days of ag...
Intraluminal fluid movement rate was measured in four regions of the rat epididymis. The fastest flow occurred in the proximal caput epididymis (18.5 +/- 3.7 mm/hour) and the slowest in the distal...
