Horseradish peroxidase (mol. diam. approximately 50 A) and ferritin (mol. diam. approximately 110 A) were used as probe molecules for the small and large pore system, respectively, in blood capillaries of the intestinal mucosa of the mouse. Peroxidase distribution was followed in time, after intravenous injection, by applying the Graham-Karnovsky histochemical procedure to aldehyde-fixed specim...

The capillary bundle model, wherein the flow dynamics of a porous medium is predicted from that independent cylindrical tubes/capillaries whose radii are distributed according to medium's pore size distribution, has been used extensively. However, as it lacks an interaction between channels, this model fails at predicting complex configuration, including those involving two-phase flow. We propo...

The aim of the study was to determine and compare structure excretory ducts Harderian gland, extraorbital infraorbital lacrimal glands laboratory rats. Object methods. Five male rats were examined by dissecting glands, from which series thin paraffin sections obtained for histological examination. Micropreparations stained with hematoxylin eosin under a light microscope.Results. It found that t...

Neutrophils are subjected to mechanical stimulation as they deform into the narrow capillary segments of the pulmonary microcirculation. The present study seeks to understand the changes in the cytoskeletal structure and the extent of biological activation as a result of this process. Neutrophils were passed through narrow polycarbonate filter pores under physiological driving pressures, fixed,...

Background: Neuropathy is one of the important complications of diabetes. Deficiency of the nerve conduction velocity (NCV) that occurs in both human diabetic neuropathy and animal diabetes models is one of the indicators for diabetic neuropathy. In the present study, we examined the effect of enalapril, angiotensinconverting enzyme inhibitor on NCV, number of endoneurial capillaries and th...
