Hyperglycemia and hypolipemia were observed in rats after the injection of sodium pentobarbital. The observed changes were independent of whether the blood was collected by decapitation or by needle puncture of the aorta. The hyperglycemic response was caused by two factors including the stress of the injection per se and the pharmacological action of the drug. Hyperlipemia was observed at 5 min postinjection. However, pentobarbital decreased plasma free fatty acids by 15 min postinjection. Both the hyperglycemia and hypolipemia responses were dose dependent.
Biochemical blood composition studies on astronauts during weightlessness flight simulation tests and during actual space flights showed some disturbances of metabolic processes. Increases in blood sugar, fatty acid and cholesterol, and urea content are noted.
Analyses of two carbonaceous meteorites have provided much of the latest evidence which seems to support Oparin's theory on the origin of life. The meteorites involved are the Murray meteorite, which fell in 1950, and the Murchison meteorite, which fell in 1969. The amino acids in the two meteorites are similar in composition. Eight of the twenty amino acids found belong to amino acids present in proteins. A number of monocarboxylic and dicarboxylic fatty acids were also found in the meteorites.
According to report, temperature of growth of thermotolerant, methane-oxidizing bacterium Methylococcus capsulatus (Bath) affects both proportion of monounsaturated fatty acids and cis/trans ratio of these acids in cell membrane. Because suboptimum growth temperature is potential stress factor, it may be possible to use such cis/trans ratios as indices of stresses upon methane-oxidizing microbial communities. Research in microbiology of methanotrophs increasing because of possible commercial exploitation of these organisms as biocatalysts or as sources of useful polymers; knowledge of effect of temperature on ability of methanotrophs to utilize methane useful in optimization of conditions of growth.
