The prevalence of serum-precipitating antibodies to Micropolyspora faeni and Thermoactinomyces vulgaris was studied by immunoelectrophoresis in 442 dairy farmers living in Hokkaido, the northernmost district of Japan. The prevalence rates of antibodies to M. faeni and T. vulgaris were 24.2 and 11.6%, respectively. The rate of antibodies to M. faeni was higher among females than males. This difference may be due to the large number of nonsmokers among females. Prevalence of antibodies to M. faeni or M. faeni and T. vulgaris was associated with a higher hay acreage and longer working hours per day in the cowshed, and not to the size of the dairy herd. These results were partly different from those reported from other countries.

Pulmonary auscultation, pulmonary function tests and radiological examination were done in 127 hospitalized patients with silicosis. Fine crackle (FC) was heard in 21.3% of patients, coarse crackle (CC) in 28.5%, rhonchi or wheeze (RorW) in 25.2% and friction rub (FR) in 5.5%. In complicated silicosis the incidence of rales was paradoxically lower than in simple silicosis (54.6 vs. 83.3%, respectively, p less than 0.05). In simple silicosis, patients with CC and/or RorW had lower %VC and FEV1/FVC%, but in complicated silicosis, the relation between the presence of rales and pulmonary functional status was not so apparent. These results suggest that in relatively advanced silicosis, all kinds of rales are heard, and in simple silicosis, rales are useful indicators of physiological impairment, but in complicated silicosis, they do not seem to be so useful.
