Biochemical studies on polychlorinated biphenyl toxicity in rats: manipulation by vitamin C.

The effects of chronic polychlorinated biphenyl (PCB) compound toxicity on L-ascorbic acid metabolism in rats have been studied. PCB treatment brought about a depression in the activities of the enzymes L-gluonolactone oxidase and dehydroascorbatase along with an increased tissue levels and urinary excretion of L-ascorbic acid. PCB toxicity drastically disturbed the normal histological pattern of the liver cells and also significantly changed the hepatic lipid composition. L-ascorbic acid supplementation to the toxicated group of animals, although could not prevent the growth retardative effect of PCB, could afford a definite protection against the enzyme activity alterations and histological changes as caused by PCB toxicity.

Gait study in evaluation of results in intramedullary nailing for femoral shaft fractures.

The present preliminary investigation conducted on six adult males whose femur shaft fractures had been fixed internally by means of Hansen-Street intermedullary nails indicated that our gait study technic helps confirm the clinical findings in such cases. Five patients, although their fractures had united and they had resumed their usual activities, were not deemed quite normal as yet and the causes for their gait abnormality were identified in the clinical examination. The gait study technic thus provided fairly accurate quantitative support of the clinical findings.

Plasma elastase levels in the elderly.

Plasma elastase levels were estimated in 190 patients of both sexes above the age of 65 with the exception of one male subject with prostatic carcinoma who was 51 years of age. There was no significant rise of fall in the elastase levels in subjects above the age of 65, nor was there any difference between the sexes. Higher values compared with the rest of the population were obtained in those subjects with arterial disease and/or cardiac disease. Subjects with cerebrovascular disease had higher values than those with cardiovascular disease. Very low values were obtained in patients suffering from malignant disease, especially carcinoma of the prostate.

Influence of lead administration on L-ascorbic acid metabolism in rats: effect of L-ascorbic acid supplementation.

1. Lead toxicated rats became severely anaemic which could be recovered to a considerable extent by simultaneous supplementation of L-ascorbic acid to these rats. 2. The concentrations of L-ascorbic acid in the liver tissues and in the urine of the toxicated rats were increased significantly while that in the kidney tissues was markedly reduced and supplementation of L-ascorbic acid to the toxicated rats could not raise appreciably this reduced L-ascorbic acid level in the kidney tissues. 3. The kidney of rats maintained on lead supplemented basal diet were enlarged significantly; the normal histological pattern of the kidney tissues was severely disturbed under the experimental condition exhibited by cellular necrosis and membrane rupture. 4. In the liver tissues of lead toxicated rats, the rate of L-ascorbic acid synthesis was enhanced and this was brought to the basal level by supplementation of L-ascorbic acid. Synthesis of L-xylulose in the kidney tissues of rats was drastically reduced under lead toxicosis and administration of L-ascorbic acid to the toxicated animals could not protect this effect.

Atmospheric pollen and fungal spores in Hamilton in 1972 estimated by the Hirst automatic volumetric spore trap.

A knowledge of the atmospheric pollen and fungal spores is necessary for the diagnosis and management of extrinsic rhinitis and asthma. The Hirst automatic volumetric spore trap has been used for the first time in Canada to identify the quantitative and seasonal incidence of these particles. The trap is easy to operate and has several advantages over the previously used gravity samplers. Tree, grass and ragweed pollens occurred in short, well-defined seasons. Fungal spores greatly outnumbered pollen by 120 to one, and occurred in long, ill-defined seasons. They included large numbers of small basidiospores and ascospores which have previously not been detected in Canada. The latter have not been considered as potential allergens; their clinical importance requires investigation.
