The effect of hunger on free fatty acid and corticosterone plasma levels in rats.

The time function of free fatty acids and of corticosterone in plasma in fed and fasted rats was investigated. Also a study of the influence of hypoxia on the concentration of plasma free fatty acids was carried out. Whereas fasting does not seem to stimulate lipolysis markedly before 12 h, 2 h of hypoxia elevate the free fatty acid level to its maximum. In the fasted condition, all values are significantly higher than corticosterone in the fed animal.

Direkte fluorimetrische bestimmung von serumlipiden auf dünnschichtchromatogrammen

Abstract A simple and rapid method for the direct quantitative analysis of thin-layer chromatograms of serum lipids is described. Estimation of phospholipids, triglycerides, cholesterolester and free cholesterol is achieved by thin-layer chromatography using a new fluorimetric technique.

Zur anwendung der Sulfophosphovanillinreaktion auf dünnschichtchromatographisch getrennte lipide

Abstract Application of the sulpho-phospho-vanillin reaction to the determination of lipids separated by thin-layer chromatography The “sulpho-phosphoro-vanillin” reaction has shown to be a simple and rapid routine method for quantitative determination of neutral lipids on thin-layer chromatograms. The technique also works well after visualization of the lipids by heating with sulphuric acid under UV light.

Ein Halothan-Anästhesiegerät für Kleintiere

A simple device for administering halothane anesthesia to small animals is described. It has been specifically designed for its low cost and accurate control of anestetic conditions.

Time function of corticosteroid levels in the blood plasma of rats under the influence of222Rn inhalation

The time function of corticosteroid level in plasma of rats under two different222Rn concentrations was investigated. Both curves show a maximum after 8 h. Whereas the higher activity of222Rn produces a second maximum after 5 days, the lower activity reaches its second maximum not before 9 days. From both time functions, a two-step mechanism in the intracellular control can be concluded.
