Blood and lymph circulation under normal conditions and in circulatory hypox

Abstract

The aim of the study was to assess the indices of blood and lymph microcirculation in the skin in healthy men under normal condition and in circulatory hypoxia. Thirty healthy men, aged 19 to 27, were examined. Evaluation of blood and lymph circulation was carried out by laser Doppler flowmetry (LDF) of the skin-the palmar surface of the base of thumb. The results showed that in occlusal period an increase in the lymph flow and decrease in blood flow were revealed, compared to normal conditions. In post-occlusal period a rapid recovery of blood circulation and slight decrease in lymph circulation were observed. Conclusion. Indices of blood and lymph circulation differ in normal conditions, in occlusal test and in post-occlusal period. Different reactivity of blood and lymph microvessels is observed in circulation recovery. The data obtained can be used for the diagnosis of blood and lymph flow disorders and assessment of local toxicosis severity under various pathological conditions.

RETRACTED: Complex assessment of parameters of central hemodynamics and microcirculation in children of 6-7 years old

“…Studies of regulation mechanisms at different levels of the circulatory system in children depending on their gender and age can serve to solve the issues of correction in cases of blood flow disorders [4,8]. The study of tissue blood flow, including capillaroscopy [3,6] and laser Doppler flowmetry [1,2] are of great importance. Analysis of heart rate variability (HRV), based on electrocardiogram parameter analysis, is a widely used method for the integral assessment of the state of the cardiovascular system [7].…”
