in the present study we administered bovine prl ( bprl ) or bovine gh ( bgh ) at a physiologic rate to hypophysectomized female rats for 2-3 days , and observed that bprl caused a small ( 16 % ) increase ( p less than 0.01 ) , and bgh a 36 % increase ( p less than 0.01 ) , in hepatic carnitine , bprl decreased serum carnitine by 24 % ( p less than 0.05 ) , and bprl and bgh each increased the liver/serum carnitine ratio by 58 % ( p less than 0.01 ) , suggesting that these hormones enhance the active uptake of carnitine from plasma .
