Mild pantothenate deficiency in rats elevates serum triglyceride and free fatty acid levels.

Pantothenate-derived coenzymes are extensively involved in intermediary metabolism, particularly in the metabolism of lipids. Using a rat model of diet-induced pantothenate deficiency, we hoped in this study to relate pantothenate status, as indicated by serum pantothenate and hepatic coenzyme A, to levels of circulating triglycerides and free fatty acids. Although commercial "vitamin-free" casein contained approximately 3 mg total pantothenate per kilogram, marked changes in serum pantothenate and hepatic CoA still occurred during weeks when rats were fed purified diets supplemented with 0 to 1600 mg pantothenate per kilogram of diet. Conditions in different experiments included ad libitum or pair-feeding of 3- or 6-wk-old rats and blood sampling from 3 to 24 h after feeding. Under most conditions of mild pantothenate deficiency in which weight differences between groups were not statistically significant, serum triglyceride and free fatty acid levels were significantly elevated in pantothenate-deficient groups. Mild pantothenate deficiency appears to have observable in vivo effects on triglyceride metabolism before severe deficiency causes significant weight loss.

Nutritional requirements of some non-pathogenic Neisseria grown in simple synthetic media.

Ten species of non-pathogenic Neisseria were grown in simple defined liquid media containing amino acids, biotin, nicotinic acid, calcium pantothenate, ferrous sulfate, magnesium sulfate, and potassium phosphate. Two of these Neisseria were induced to grow with glutamic acid as the carbon and nitrogen source. The remaining eight Neisseria grew in glutamic acid medium supplemented with from one to four additional amino acids, lactate, or lactate and glucose. A strain of N. flavescens grew in the absence of added growth factors whereas the remaining nine species of Neisseria required either biotin or nicotinic acid; pantothenate was required by two and was stimulatory for three of these species. Use of carbohydrates by the non-pathogenic Neisseria in synthetic medium was tested. Two strains failed to use any of the 14 carbohydrates tested; one strain used only glucose; the remaining seven strains used fructose, glucose, maltose, and sucrose to varying degrees.
