Testicular capillary permeability:the movement of luteinizing hormone from the vascular to the interstitial compartment
UI vascular permeability testis rat
2009/2/13
It has previously been shown in several species that pulses of luteinizing hormone (LH) in peripheral serum are followed within 10-20 minutes by pulses of testosterone. Whether or not LH pulses di...
Long-term alterations in the permeability of the blood-testis barrier following a single intratesticular injection of dilute aqueous glycerol
Blood-testis barrier permeability glycerol seminiferous tubules Sertoli cells
2009/2/12
The mechanism whereby glycerol exerts its antispermatogenic action is not known. The objective of this study was to determine, with the use of [3H]inulin and [125I]albumin by in vivo and in vitro ...
Characterization of a new superfusion, two-compartment culture system for Sertoli cells:influence of extracellular matrix on the cell permeability and dynamics of transferrin secretion
two compartment culture system sertoli
2009/2/6
A new superfusion two-compartment culture system was developed in the laboratory of the author and was used to investigate the influence of testicular extracellular matrix on barrier formation by Se...
The inter-Sertoli tight junction permeability barrier is regulated by the interplay of protein phosphatases and kinases:an in vitro study
Testis Sertoli cells protein tyrosine phosphatase protein
2008/12/29
The timely opening and closing of inter-Sertoli cell tight junctions in the rat testis are essential cellular events in the completion of spermatogenesis. They permit the passage of preleptotene and...
The permeability of the microvasculature of the perfused rat testis to small hydrophilic substances
permeability microvasculature perfused rat testis small hydrophilic substances
2008/12/25
The permeability-surface area products (PS) for sodium, Cr-EDTA, and cyanocobalamine (CoB12) have been determined in isolated perfused rat testes, using the single-passage multiple tracer techni...
Chimpanzee(Pan troglodytes)Spermatozoa Osmotic Tolerance and Cryoprotectant Permeability Characteristics
Cryopreservation membrane permeability
2008/12/23
Osmotic properties of chimpanzee spermatozoa were studied at 22°C. An electronic particle counter was used to determine the isosmotic cell volume, and the volume response after exposure to four comm...
