Effects of human fetal hepatic stimulator substance on D-galac-tosamine-induced liver necrosis in rats / 第三军医大学学报

ABSTRACT

The effects of human fetal hepatic stimulator substance (h-HSS) and liver cytosol (h-FLC) on the survival rate,the intensity of liver damage,and liver regeneration in rats with liver necrosis induced with D-galactosamine were observed.The physico-chemical properties of h-HSS were preliminarily determined.It was found that both h-HSS and H-FLC could markedly increase the.survival rate of the rats with toxic liver necrosis,significantly decrease the serum level of ornithine carbamoyl transferase and mitochondria aspartic trans-aminase,improve the hepaplastin activity,and elevate the incorporation rate of 3H-thymidine with liver DNA.h-HSS was stable after heated to 95℃ for 30 minutes,and sensitive to trypsin treatment.It demonstrated one major band at 15 000 daltons and 3 minor ones at 24 000,34 000,and 40 000 daltons respectively on sodium dodecyl sulfate-polyacrylamide gel electrophoresis.The relative content of the major band was 47.57%.
