LACTATE RELEASE FROM THE SUBCUTANEOUS TISSUE IN LEAN AND OBESE MEN

Lactate concentration in the subcutaneous interstitial fluid and adipo se tissue blood flow (ATBF, ml/100 g . min) were simultaneously measur ed with the microdialysis technique combined with Xe-133 clearance in the abdominal and femoral subcutaneous adipose tissue in nine lean and nine obese men. The studies were performed both in the postabsorptive state and 2 h after an oral glucose load and the results compared to the lactate levels in arterialized venous plasma.
