title: Sub-chronic diclofenac sodium induced alterations of alkaline phosphatase activity in serum and skeletal muscle of mice.
abstract: The present study has been carried on changes in activity of alkaline phosphatase in serum and gastrocnemius muscle of mice after sub-chronic use of diclofenac. Mice in experimental group received diclofenac (10 mg/kg body wt /day) for 30 days while control group received normal saline. Alkaline phosphatase was assayed in muscle and serum and its activity was localized histochemically in muscle. Results showed that diclofenac induced changes in specific activity of alkaline phosphatase at different periods of treatment variably compared to control group. Specific activity of alkaline phosphatase decreased significantly in gastrocnemius initially (48.74%), increased thereafter (132.96%) and slight decrease (13.97%) was noticed after 30 days. In serum, the specific activity of alkaline phosphatase decreased slightly after 10 days (18.78%), increased in the middle of the treatment period (132.04%) as well as showed increase (109.09%) compared to control group after 30 days stage of investigation. These findings were also confirmed by electrophoretic studies in muscle.
