Biochemical changes in rats with different behavioral characteristics under conditions of metabolic stress.

Food deprivation is an extreme state of the functional feeding system, which is reflected in the character of changes in the activity of central and peripheral components selectively included in the system. We studied the dynamics of coenzyme Q10 levels and spectrum of omega-3 and omega-6 polyunsaturated fatty acids in the blood serum, liver, and brain as well as LPO intensity in the serum and liver in behaviorally passive and active rats under conditions of food deprivation. Our results indicate that adaptive and compensatory processes during acute metabolic stress depend on the initial behavioral characteristics of the animals.

Biochemical features in rats with different behavioral activity under conditions of emotional stress.

Adaptive capacities of the organism under conditions of emotional stress are determined by individual complex of anti-stress protective mechanisms. We studied the content of coenzyme Q10 and the spectrum of polyunsaturated fatty acids omega-3 and omega-6 in the serum, liver, and brain, and LPO intensity in the serum and liver of behaviorally active and passive rats under conditions of acute emotional stress. The differences in the formation of adaptive responses in animals with various behavioral activities were demonstrated.

Biochemistry of blood plasma and some parameters of antioxidant status in rats with polyhypovitaminosis of varying severity.

In rats with profound vitamin deficiency, blood plasma level of triglycerides significantly decreased by 1.6 times, potassium ions by 5%, uric acid by 23%, ALT and AST by 1.4 times, while the levels of glucose increased by 32%, iron by 31%, urea by 58%, and alkaline phosphatase by 19%.

[Effect of fatty component in ration and coenzyme Q10 on indices of rat lipid metabolism in ontogenesis].

The studies made on rats of 1, 3, 6 and 12 months with fish, palm and linseed oil included in the ration in combination of KoQ10, showed that beginning from young age till 12 months fatty acid composition of liver depended of fat component in the ration. Long-term consumption of fish fat with age results in significant increase in omega 3 fatty acids. In this case the omega 6 fatty acids level remained rather high being indicative of organism adaptation and inclusion of compensatory mechanisms supporting the required level of omega 6.

[The effect of fatty component of diet and coenzyme Q10 on rat sufficiency with vitamins-antioxidans in chronic experiments].

The full replacement of fatty component of a diet (10% of feed mass, sunflower-seed oil and lard 1:1) on enriched with alpha-tocopherol acetate fish oil or on linen oil under additional coenzyme Q10 intake (100 mg per 1 kg body weight) within 12 months led to a significant vitamin A blood serum decrease on 23-31%, 2-2,8 fold fall of vitamin E blood serum level and vitamin C rat liver diminution due to significant dehydroascorbic acid reduction on 28-45%. In both cases, the intensification of POL was not observed. The use of palm-oil as a fatty component led to a significant vitamin A blood serum decrease on 31%, but didn't effect on all other investigated parameters.
