Lysosomal acid phosphatase decrease in nutritional encephalopathy in chicks

Area of Science:

• Biochemistry
• Neuroscience
• Nutritional Science

Background:

• Vitamin E is crucial for neurological health.
• Oxidized oils can impact nutrient availability and health.
• Acid phosphatase is an enzyme involved in cellular processes.

Purpose of the Study:

• To investigate the effects of vitamin E deficiency and thermally oxidized safflower oil on chick encephalopathy.
• To examine the activity of acid phosphatase in the cerebellum, cerebrum, and liver of affected chicks.

Main Methods:

• Inducing encephalopathy in 14-day-old chicks using a vitamin E-deficient diet with 15% thermally oxidized safflower oil.
• Measuring bound and free acid phosphatase activity in the cerebellum, cerebrum, and liver of deficient and control chicks.

Main Results:

• Chicks fed a vitamin E-deficient diet exhibited encephalopathy.
• Markedly lower bound acid phosphatase activity was observed in the cerebellum of deficient chicks compared to controls.
• Free acid phosphatase activity also showed a tendency to be lower in the cerebellum of deficient chicks.
• No significant differences in enzyme activities were found in the cerebrum and liver.

Conclusions:

• Vitamin E deficiency, exacerbated by thermally oxidized safflower oil, leads to encephalopathy in chicks.
• Cerebellar bound acid phosphatase activity is significantly reduced in vitamin E-deficient encephalopathic chicks.
• The cerebellum appears to be a primary target for the enzymatic changes associated with this induced neurological condition.
