Popis: The rate of triacylglycerol entry into plasma in 14- to 15-day-old suckling rats was measured using the Triton WR1339 method. When the pups were left with the mother and allowed to nurse continually, the rate was 31.8 +/- 2.3 mumol/hr per rat. If the pups were removed from the mother with full stomachs and kept in a warm box at 30–32 degrees C, the rate was 12.5 +/- 1.5 mumol/hr per rat. The rate of triacylglycerol output from the intestine measured in lymph duct-cannulated animals (kept in a warm box at 30–32 degrees C) was 14.9 +/- 2.7 mumol/hr per rat. Triton treatment of lymph duct-cannulated animals caused only a small increase in plasma triacylglycerol concentration (less than 2 mumol/hr per rat). These data suggest that nearly 100% of plasma triacylglycerol arises from intestinal input in the suckling rat.
