[Blood gas analysis of forearm veins--at rest and after exercise of forearm muscles and laser Doppler flowmetry of skin on the back of the palm--use in evaluation of microcirculation in diabetes type 2]. / Gazometria zylna obwodu konczyny górnej--spoczynkowa i po wysilku miesni przedramienia oraz laserowa przeplywometria dopplerowska skóry grzbietu dloni--zastosowanie do oceny funkcji mikrokrazenia w cukrzycy typu 2.

ABSTRACT

The aim of the study was to compare of nondominant forearm microcirculation in adult-type diabetes and healthy subjects with use of venous blood gasometry (vbg) sampled from basilic vein before and after exercise of antebrachial muscles and with use of laser doppler fluxometry (LDF) with optode localized in dorsal palm surface. Examinations were performed in groups of 16 diabetic patients (aged 43.5 +/- 5.7) and 16 healthy subjects (aged 39.3 +/- 7.8). After exercise of antebrachial muscles in diabetic patients in vbg were pH higher, pO2 and satO2 lower than in healthy subjects, pCO2 and -HCO3 were not different in both group. In LDF in diabetic patients impaired hypraemic reaction, impaired heating to 40 degrees C reaction and hyperaemic reaction in this temperature were found.
