EFFECT OF NICOTINIC ACID ON STEROL BIOSYNTHESIS IN SACCHAROMYCES CEREVISIAE.

IN 1955, Altschul et al. reported1 that large doses of nicotinic acid, but not of its amide, decreased serum cholesterol-levels in man and rabbit. This finding has been confirmed by many workers2. Despite several investigations of mechanisms, however, the locus of the nicotinic acid effect remains unknown3,4. We wish to report an effect of high concentrations of nicotinic acid on sterol biosynthesis in yeast. This effect may account for the hypocholesteremic action of nicotinic acid.

Hyperlipemic Effect of ACTH Injections in the Chicken

THE blood lipid responses observed following injections of adrenocorticotropin (ACTH) and various adrenal cortical hormones into man and animals are contradictory. In some instances cortisone injections (6–100 days) increased plasma cholesterol levels in man (Adlersberg et al. 1951), the rabbit (Dury, 1956; Gordon et al., 1954; and Wang et al., 1955) and the dog (Wang et al., 1955), but decreased cholesterol levels under different circumstances in man (Oliver and Boyd, 1956) and the rabbit (Wang et al., 1955).Cortisone, on the other hand, was found to be without effect on lipid metabolism in the chicken, as indicated by a failure to cause liver lipid deposition (Dulin, 1956) and failure to alter whole blood total lipid levels (Baum and Meyer, 1960).Results similar to those following cortisone injections have been reported following ACTH injections (7–10 days) in man (Adlersberg et al., 1951), the rabbit and the dog (Wang et al., …

Symposium on significance of lowered cholesterol levels.

It is now well recognized that serum cholesterol levels in man can be lowered by the judicious substitution of one type of dietary fat for another. 1 However, it is relevant to inquire whether a patient can be assured that such a radical change in his dietary habits will prevent coronary occlusion or a cerebral vascular accident. This question must unfortunately be answered in the negative, for it has not been proved that lowering the level of serum cholesterol will prevent either the occurrence or the end-results of atherosclerosis. At the present time, clear proof of this proposition still seems many years away. Nevertheless, there are many reasons for believing that there is some connection between cholesterol metabolism and atherosclerosis, and, while waiting for elucidation of this relationship by laboratory workers, it seems justifiable to apply certain dietary procedures that are theoretically harmless and possibly beneficial. We have stated previously
