Further Studies on Aminopeptidase-M in Blood in Children with Cholestatic Liver Diseases and Viral Hepatitis	1999		.txt	text/plain	4601	284	71	Recently, we have shown that in childre n with chole stasis of diffe ring e tiologie s incre ase d se rum met-enkephalin occurs concom itantly with highly ele vate d se rum aminope ptidase -M activity and that both parame ters were appare ntly not affe cted by a short-te rm treatment with ursode oxycholic acid (39, 40) . There fore , in this study we attempted to furthe r characterize and compare the serum aminope ptidase -M activity in he althy childre n, childre n with chole static live r dise ase , and childre n with chronic or acute he patitis due to hepatitis B virus (HBV) infe ction. As shown in Figure 2a , the e nzyme activity increased from 45 6 5 (undilute d se rum, pH 7.4) up to maxim al value s of 880 6 90 pg/min/ml (80-fold dilute d serum; value s are means 6 SEM) .	./cache/cord-303646-uxewsyli.txt	./txt/cord-303646-uxewsyli.txt
