Left main coronary block in a nineteen-year-old woman.

A 19-year-old woman had angina on exertion, which had existed for 4 years. An exercise test was strongly positive, and selective coronary angiography showed 95% block of the left main coronary artery at its ostium. The patient underwent a successful aortocoronary bypass to the left anterior descending coronary artery. After 1 year and 10 months, she continues to be asymptomatic.

Production and utilization of extracellular slime by Pseudomonas solanacearum and its role on survival at different relative humidities.

Pseudomonas solanacearum produced maximum slime with glucose and least with glycerol. With increasing concentration of glucose, slime production increased. The maximum slime production was observed in the medium containing 1% glucose. The slime contained sugars, sugar acids and amino acids. The bacterium utilized the slime as a sole source of carbon. The growth on slime was more or less comparable to the growth on 0.1% glucose. The viability of the bacterium in slime increased as the relative humidity (RH) decreased. At higher RH the slime absorbed moisture and the viability was reduced. The bacterium could survive only for short period at higher RH under sunlight not in shade. The sunlight seemed to accentuate the harmful effect of RH on the bacterium.

Degradation of carboxin (Vitavax) and oxycarboxin (Plantvax) by Pseudomonas aeruginosa isolated from soil.

Pseudomonas aeruginosa capable of utilizing carboxin and oxycarboxin as sole sources of carbon and nitrogen was isolated from red sandy loam soil perfused with the solutions of these fungicides. The bacterium hydrolyzed oxycarboxin via the intermediate compound 2-(vinylsulphonyl) acetanilide liberating 2- (2-hydroxyethylsulphonyl) acetic acid and aminophenol, whereas carboxin was first oxidized to its sulphoxide and then to its sulphone before hydrolysis. Further hydrolysis of aminophenol by the organism resulted in the accumulation of ammonium which was partly oxidized to nitrite. Nitrite accumulated in the medium without further oxidation to nitrate.

Dehydrogenase activity and microbial population in a red sandy soil amended and unamended with incubation.

Incubation of single bulk sample of freshly collected red sandy soil in trays showed immediate response to added nutrients both in dehydrogenase activity and bacterial and fungal populations. The prevailing acidic pH might have been responsible for the observed response of fungi as well. Actinomycetes population did not fluctuate. It was therefore suggested that TTC dehydrogenase technique for measuring the biological activity could be applicable to coarse-textured and more open soils. There were indications that fungi contributed to the soil dehydrogenase activity as well.

Effect of lime-pelleting on nodulation and yield of soybean grown in acid soil.

An experiment for studying the effect of lime-pelleting of inoculated seed of soybean [Glycine max. (L.) Merr.] on nodulation, growth, and grain yield was undertaken in red sandy loam of Bangalore, having a pH of 4.0. The results indicated that inoculation alone increased significantly nodulation, plant dry weight, and grain yield. But inoculation plus lime-pelleting significantly increased the dry weight of nodules and plants, but not the grain yield. However, lime-pelleting was found to be beneficial though not essential in acid soils.
