摘要:

A Pulmonary Function Survey involving a questionnaire and pulmonary function testing was carried out in 14 plants of a large cotton textile manufacturing corporation. The edited records of 6,631 employees were analyzed to help identify the prevalence and location of byssinosis and other respiratory ailments and to explore the environmental conditions associated with them. A majority of the complaints of byssinosis were found among the relatively small subset of employees located in the high dust work areas of opening, picking, and carding. Byssinosis was significantly associated with bronchitis. Smoking was significantly associated with byssinosis for employees in opening, picking, and carding. While 3% of the population had subjective symptoms (history) of byssinosis, 0.8% indicated both symptoms and objective sign by a 10% or greater drop during the working day of the one-second forced expiratory volume (FEV1). The techniques commonly used to predict FEV1should employ race as a predictive factor.

摘要:

Isoelectric focusing in thin-layer polyacrylamide gel is a method with high resolving power, e.g. for urinary proteins. Therefore more information can be obtained with this method than with ordinary electrophoresis. The present version of the method has a high capacity and allows study of up to 25 samples in parallel on each gel. Only a little more than one hour is required for separation. A sensitive staining procedure is used which allows detection of as little as 0.1 µg of protein in each zone. When effects on the kidney are present more than 20 different protein zones can sometimes be separated. Evaluation is made by densitometry as well as by comparison and classification of patterns. Urine samples have been studied from workers with varying exposure to cadmium lead and various chlorinated hydrocarbons, and patients with glomerulonephritis, pyelonephritis, nephrosis and mixed tubular and glomerular diseases. Typical tubular patterns, i.e. as developed in association with cadmium exposure were characterized by elevated excretion of β1microglobulin. Other types of kidney malfunction showed different features.
