Endocrine Control of Serum Alkaline Phosphatase Activity in the Chicken

Thyroidal control of serum alkaline phosphatase level in the chicken.

It has been reported that serum alkaline phosphatase level is extremely high in the young chicken but reaches a low level in the adult(Common, 1936; Tanabe and Wilcox, 1960a). Thyroid hormone secretion rate on the basis of unit body weight has been noted to be higher in the young chicken than in the adult (Schultz and Turner, 1945 ; Himeno et al., 1960). Recently, Tanabe and Wilcox (1960b)repor...

Histochemical Study of Alkaline Phosphatase Activity in the Chicken Intestine

The distribution of non-specific alkaline phosphatase (AP) in normal duodenum, rest small intestine and caecum of chicken has been studied by a catalytic histochemistry method. Embryos and chickens ranging between day 11 prior to and day 60 after hatching were used and the findings of AP reaction were correlated with the age. In the small intestine, during foetal life, the AP activity started t...

Chicken Intestinal Alkaline Phosphatase

Purified chicken intestinal alkaline phosphatase is active at pH 8 to 9, but becomes rapidly inactivated with change of pH to 6 or less. Also, a solution of the inactivated enzyme at pH 4.5 rapidly regains its activity at pH 8. In the range of pH 6 to 8 a solution of purified alkaline phosphatase consists of a mixture of active and inactive enzyme in equilibrium with each other. The rate of ina...

Alkaline Phosphatase in Serum is a Marker of Human Toxocariasis

Background: The present study was carried out on the human population of Kashmir valley to evaluate the status of the biochemical parameters of infected population. Materials and Methods: Blood samples were collected from 514 individuals, 298 (57.97%) males and 216 (42.02%) females, 187 (36.38%) were found sero-positive for human toxocariasis. Results: Alkaline phosphatase level was found highe...
