Alkaline phosphatase activity in peripheral nerves and endothelial cell cultures in leprosy.

Alkaline phosphatase activity in leprosy nerves was studied. The activity was mainly in blood vessels and was maximum in healthy nerves. Low levels were seen in crush injury. In leprosy lower levels were in BT than LL cases. Endothelial cells (in vitro) released alkpase when infected with live bacilli only. No response was observed with heat killed bacilli.
