Zinc carnosine works with bovine colostrum in truncating heavy exercise–induced increase in gut permeability in healthy volunteers
clinical trial gut growth injury nutriceutical repair
2016/6/29
Background: Heavy exercise causes gut symptoms and, in extreme cases, heat stroke that is due to the increased intestinal permeability of luminal toxins.
Comparison of mass transfer models for determination of the intestinal permeability
Mass transfer Permeability Laminar flow Perfusion Mixing tank model
2009/12/18
Background and the purpose of the study: In determination of the permeability of the intestinal wall by external perfusion techniques, several models have been proposed. In the present study three mod...
Increased blood-brain barrier permeability to tetracycline in rabbits under dysbaric conditions
decompression tetracycline permeability rabbits
2009/7/17
Alteration of the blood-brain barrier (BBB) by dysbaric exposure may have relevance in several areas of hyperbaric medicine. Drugs administered to persons exposed to dysbaric conditions, e.g., divers,...
Changes in blood-brain barrier permeability to drugs in decompressed rats
decompression human blood brain barrier animal rat drug
2009/7/16
A study has been made of changes in permeability of the blood-brain barrier (BBB) to drugs following exposure to compression-decompression. Fifty-five rats were exposed to 6.1 b (abs) air for 90 min a...
Pharmacologic modulation of pulmonary vascular permeability during air embolism
pulmonary animal rat embolism AGE Pharmacologic air
2009/6/8
Pulmonary air embolism induces the generation of vasoactive and cytotoxic substances leading to lung injury. In the present study we investigated, in isolated and perfused rat lungs, the involvement o...
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...

In-vitro percutaneous absorption of losartan potassium in human skin and prediction of human skin permeability
Transdermal Losartan potassium rat and mice skin Eudragit Enhancer
2007/2/28
This study describes the feasibility of transdermal controlled administration of Losartan potassium (LP) across human cadaver skin. Study also defines the influence of capsaicin, sex and site of appli...
Permeability of rat IgE across rat aortic endothelial cell is enhanced by histamine
IgE endothelial cells histamine permeability
2006/3/3
On the basis of results from the present study, histamine, acting via H2 receptors, enhances the permeability of rat IgE across the RAEC mono-layer. The increased permeability of endothelial cells ind...
