We used an analytical color fluorescence electron microscope to observe cathodoluminescence (CL) in the corpus luteum of rat. CL was emitted from lipid droplets and has a typical spectrum of two peaks at wavelengths of 320 and 430 nm. The

The present study was undertaken to investigate the mechanism for control of hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase and cytochrome P-450 side chain cleavage (P-450scc), enzymes involved in the synthesis and processing of cholesterol in the corpus luteum of pregnant rats. The

4-Aminopyrazolopyrimidine (4-APP) treatments to rats for 3 days induced 2-fold increase of circulating ACTH and 11-fold increase of adrenal 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase mRNA compared to NaCl-treated controls. This in vivo model was used to study the effect of

Treatment of rats with 10 mg.kg body wt-1 day-1 4-aminopyrazolo[3,4-d]pyrimidine (APP) for 2 days markedly reduced serum cholesterol and phospholipids. This was associated with large decreases in the principal component of alveolar surfactant, the disaturated phospholipids (DSP), in the lamellar

Maternal low density lipoprotein (LDL) is the principal source of cholesterol substrate for progesterone biosynthesis in the primate placental syncytiotrophoblast. The relationship of LDL-cholesterol availability and other potential cholesterol-yielding pathways to placental progesterone production have not, however, been demonstrated in
