The composition and distribution of steryl esters in human diseased or developing brain tissue has been studied. The abnormal brain conditions included sudanophilic leukodystrophy, multiple sclerosis plaque, subacute sclerosing panencephalitis, and a

Although all parts of the geranium plant ( Pelargonium hortorum ) are capable of synthesizing sterols and triterpenes and their esters in vitro from mevalonic acid-[2- 14 C], the aerial portions are more active than other tissues. All plant parts wer

The activities of five hydrolytic enzymes (acid and alkaline phosphatase, hexosaminidase [N-acetyl-beta-D-glucosaminidase], beta-galactosidase, and beta-glucorinidase) were measured in reconstituted homogenates of lyophilized human brain tissue and p

Further examination of the neutral lipid fractions derived from brain tissue of two patients afflicted with adrenoleukodystrophy has demonstrated the presence not only of free cholesterol and cholesteryl ester, but also of appreciable free fatty acid

The results of neurochemical examination of brain tissue derived from 2 cases of adreno-leukodystrophy have been presented. Both white and grey matter contained sudanophilic material. Although free fatty acid was also present, cholesteryl ester accou

Treatment of developing rats with a combination of hypocholesterolemic agents, zuclomiphene in combination with AY9944 and Triparanol, resulted in the accumulation of Δ 7 sterols in the brain. Abnormal levels of desmosterol and zymosterol were also

The hypocholesterolemic agent zuclomiphene was found to inhibit sterol formation from [2-14C]mevalonic acid in cell-free preparations of developing rat brain. This inhibition was found if zuclomiphene were added to an incubation of normal brain. If t

— The effect of zuclomiphene, a hypocholesterolemic agent, on developing rat CNS cholesterol biosynthesis was examined. Sterol content and composition was studied in relation to age in four regions of the CNS, cerebrum, brain stem, spinal cord and

The translocation of several plant sterols and a triterpene was studied in geranium and sunflower plants. Upward translocation of sitosterol-[ 14 C] and β-amyrin-[ 14 C] was shown within 48 hr to the upper parts of a geranium plant sectioned previou
