title: Microsomal alkaline phosphatase activity in retinol deficiency induced albino rats.
abstract: The investigations showed a significant decrease in the alkaline phosphatase activity of retinol deficient liver (48.6%), kidney (65.8%) and spleen (61.9%), as compared to the controls (100%). An increase in Vmax and Km by 12 to 51.5% and 90.4 to 189%, respectively, was observed in all the tissues in the retinol deficient group, as compared to the controls. Subsequent freezing and thawing reduced the activity of alkaline phosphatase by 22.5 to 35.8% in the experimental group; whereas the reduction in the control group ranged from 8.8 to 21.5%. In the presence of lectins and detergents the activity of alkaline phosphatase decreased in both the groups to different levels.
