Experimental sepsis in rats induces a restriction in spontaneous food intake and a drop in liver glutathione, cytochrome P-450 (P-450) and aminopyrine demethylase (AD) activity. The present study was designed to assess the effects of antibiotics alone or when combined with food deprivation on these variables. Eighty-nine male Sprague-Dawley rats were assigned to six groups: control (C), acute infection (experimental pyelonephritis, I), acute infection with antibiotics and food given ad lib. (IA), control with antibiotics (CA), acute infection with antibiotics pair-fed to I (IAR), and sham-operated pair-fed to I (SR). Liver glutathione, P-450 and AD activities were reduced by 45.2, 79.8 and 41.2% respectively in group I. Glutathione and AD significantly increased only in those infected rats given antibiotics and allowed free access to food. P-450 did not normalize within the study period in infected rats receiving antibiotics and food repletion. The risk of drug hepatotoxicity in acute septic states is therefore closely related to the nutritional status. From this point of view, nutritional support is almost as important as treatment of infection.

Noticeable decrease in microsomal protein level MOS terminal component--cytochrome P-450 and MOS median link--cytochrome b5 contents in microsomal fraction implicated in renal pathologic process was established in development of acute unilateral pyelonephritis. These findings reduction expression directly depended on severity and pathologic process development degree. One of the main causes led to reduction in cytochromes P-450 and b5 level and inhibition proteins biosynthesis may be influence of toxic products which are generated in substance exchange involved in prevalence of catabolic processes in injured kidney and intensification in endogenous intoxication syndrome on renal structures. Implication of many other factors effecting decrease in microsomal hemoproteins and protein levels in the damaged kidney in above pathology showed necessity to perform further investigations in the field given.

This study was designed to determine the effect of ornithine alpha-ketoisocaproate (O-KIC), a compound reducing muscle protein breakdown in physiological conditions, on liver factors involved in drug metabolism in rats with acute retrograde pyelonephritis. 91 rats were assigned to 7 groups differing in the level of food intake, induced infection, and the treatment by O-KIC (168 mg/kg bw/day). Rats were killed on the third day. O-KIC increased nitrogen balance and weight gain in controls, but not in malnourished infected or non-infected rats. Liver glutathione was significantly reduced by O-KIC in malnourished infected and non-infected rats. Though O-KIC induced a rise in liver microsomal proteins in control and infected animals, it decreased cytochrome P-450 in controls, and aminopyrine demethylase in both control and infected groups.
