Couperosis is a skin condition in which there disorder of the covering face with network dilated capillaries; it usually an inherited condition. The development couperosis influenced by weakening capillaries, chronic diseases that predispose to blood circulation disorders.
 Aim study. To assess effect cosmetic products on couperose facial skin.
 Methods. Mixed method research. In 2023...

CRONE, C. The permeability of capillaries in various organs as determined by use of the ‘Indicator Dzffusion’ method. Acta physiol. scand. 1963. 58. 292-305. The theory of a single injection technique, the ‘Indicator Diffusion’ method, for quantitative studies of capillary permeability is developed. It is shown that the permeability of a capillary area can be expressed by three parameters: the ...

In humans, the majority of studies demonstrate an age-associated reduction in the number of capillaries surrounding skeletal muscle fibers; however, recent reports in rats suggest that muscle capillarization is well maintained with advanced age. In sedentary and trained men, aging lowers the number of capillaries surrounding type II, but not type I, skeletal muscle fibers. The fiber type-specif...

Alzheimer's disease is the most common cause of irreversible dementia, affecting mostly the presenile and senile age, shaping a tragic profile in the epilogue of the life of the suffering people. Due to the severity and the social impact of the disease an ongoing research activity is in climax nowadays, associated with many legal, social, ethical, humanitarian, philosophical and economic consid...

A Cavrnous Hemangioma is an abnormal tangle of tightly packed thin walled capillaries that are probe to bleeding.

The gradient of permeability along the capillaries of voluntary muscle and the capillaries and venules of skin exists independently of the hydrostatic conditions, though influenced by them. Its presence cannot be explained by a graded tonic contraction of the capillaries. The evidence,-like that of previous papers,-points to local differences in the barrier offered by the wall of these vessels ...

The effect of steroids on the uptake and release of K+ by capillaries isolated from rat brain was investigated. 86Rb’ uptake was used as a transport analog of K+. The uptake of 86Rb’ by the capillaries was markedly inhibited by ouabain. The ouabain sensitive fraction of 86Rb’ uptake was inhibited by corticosterone with an 150 of 8 X 10m4M. Inhibition was immediate in onset and rapidly reversibl...

Skeletal muscle blood flow is reduced and O(2) extraction is increased at rest in chronic heart failure (CHF). Knowledge of red blood cell (RBC) flow distribution within the capillary network is necessary for modeling O(2) delivery and exchange in this disease. Intravital microscopy techniques were used to study the in vivo spinotrapezius muscle microcirculation in rats with CHF 7 wk after myoc...

Glass capillaries with diameters of 1.5 mm were used. The tips of the capillaries were sharpened by a flaming-brown micropipette puller (Model P-1000, Sutter Instrument, USA) to obtain needle-shape capillaries. Anhydrous alcohol (99.5%) and anhydrous toluene (99.9%) were purchased from Shimakyus Pure Chemical (Osaka, Japan) and J. T. Baker (Phillipsburg, NJ, USA). MTS (Methyltrichlorosilane, CH...
