Non-phosphorylative transglucosylation in the serum and liver of mice with transplantable leukaemias.

Transglucosylative activity was examined in the serum and liver of mice with transplantable leukaemias, using following synthetic substrates: p-nitrophenyl-N-maltoside, as well as p-nitrophenyl-N-glucoside and maltose. In the serum of mice with leukaemias L 1210/ara-C and L 1210/CH3G as well as lymphoma AKSL-4 and plasmocytoma ADJ PC-5 there was observed a statistically significant decrease in the transglucosylative activity compared with the control group. Examination of extracts from the liver of mice proved increased transglucosylative activity at leukaemias L 1210/ara-C and AKSL-4. No significant changes in the transglucosylative activity were found at leukaemias L 1210/CH3G and ADJ PC-5.
