Acetylcholinesterase activity in developing rat brain during undernutrition.

ABSTRACT

The effect of low protein diet on rat brain AChE activity has been studied during gestation, lactation and postweaning periods. There was decrease in enzyme activity of pups undernourished either during gestation and lactation or lactation alone, the decrease being maximum in 18-day-old pups. In postweaning rats, a significant decrease was observed after 2 and 4 weeks of undernutrition compared to the control. However, the effect of undernutrition was annuled by 2-week rehabilitation, thereby indicating that imposed undernutrition only delays the normal level of the enzyme. Moreover, it appears that the enzyme activity depends both on the nutritional status and the development age.
