Airway obstruction in achalasia.

A man with a mediastinal mass shadow detected on chest roentgenogram was diagnosed as having achalasia by barium swallowing study. Megaesophagus caused by achalasia produced airway obstruction. Maximum expiratory-inspiratory flow volume curve identified that peak flow rate decreased in early expiration, and the ratio of expired to inspired flow at 50 percent of vital capacity was below 0.9, aggravated by 250 ml water intake. Deformation of the tracheal shape was proved easily.

Hoarseness as an initial manifestation of sarcoidosis.

A patient had hoarseness, the cause diagnosed as left recurrent laryngeal nerve palsy derived from enlarged sarcoid mediastinal lymph nodes. His symptoms were alleviated by steroid therapy, which was accompanied by the improvement of mediastinal lymph node swelling noted on chest x-ray film. Hoarseness may be listed as one of the symptoms of sarcoidosis.

[Studies on the change of spontaneous locomotor activities in rats due to forced exercise (author's transl)].

The authors have devised an apparatus for monitoring the spontaneous locomotor activity of rats, with which the patterns of locomotor activity under the condition of light-dark cycle (light period: twelve hours from 6 a.m., dark period: the other half of the day) were analysed. In addition, changes in locomotor activities due to forced exercise (swimming) were recorded. The results obtained were as follows: 1. The patterns of locomotor activities in rats recorded by the monitor showed the same patterns as reported already by other researchers. The authors believe that this new apparatus can be used practically as a locomotor activity monitor. 2. Due to exhaustive exercise by swimming, changes of the ultradian rhythm in rats were observed. 3. By loading of swimming, locomotor activities in rats decreased significantly, especially in the dark period. These results suggest that this newly devised apparatus is useful as a locomotor activity monitor, and that the fatigue in rats caused by physical load can be shown as the change in locomotor activities.

[Studies on the items for diagnosis of the vibration disease. Part 1. Examination of healthy workers using vibratory tools].

1,215 male workers using bush cleaners in Hokkaido were examined by the method based on the notification of the Labor Standard Bureau. The results obtained from clinically normal 548 workers among them were analysed especially on the finger skin temperature, vibratory sense threshold, maximum grip strength. 1) Data of the vibratory sense threshold, maximum grip strength and endurable grip strength showed normal distributions. Data of the finger skin temperature, however, showed a skewed distribution. 2) In parallel with aging, the vibratory sense threshold increased, in other words, lowered in function, and the maximum grip strength lowered. 3) The endurable grip strength measured by the five-time repetition method decreased along with aging. 4) Values of one-tail limit of the finger skin temperature were calculated in all 548 workers, and those of the vibratory sense threshold, maximum grip strength and endurable grip strength were done in each age group. The values were compared with the already proposed criteria and discussed.

Bacteriological investigation on biopsy specimens from patients with sarcoidosis.

Biopsy specimens, mostly lymph nodes, removed under aseptic conditions, were emulsified and the homogenate was inoculated in various media, which were incubated aerobically or anaerobically. Only Propionibacterium acnes was isolated in high incidence and the highest concentration of bacteria was 6.5 X 10(5) per g tissue: 28 and 31 out of 40 lymph nodes were positive on solid and on liquid media, respectively. P.acnes was also isolated from control non-sarcoidosis lymph nodes: 4 and 8 out of 14 were positive on solid and on liquid media, respectively. The highest concentration of bacteria was 1 X 10(4). A bacterial component derived from P. acnes was used for the passive hemagglutination test to estimate antibodies against the bacterium and also for skin test on patients. These results showed only slight differences between patients with sarcoidosis and control patients. No other bacteria or fungi were isolated.
