COSMIC RADIATION AND TUBERCULOSIS. IV. INFLUENCE OF COSMIC RADIATION ON TUBERCULOSIS AT HIGH ALTITUDE (3,130 M) AND AT SEA-LEVEL
At high altitude (3,130 m) tuberculous mice exposed to cosmic radiation under 10 cm of lead showed significantly greater mean survival time and a significantly greater number of survivors than tuberculous mice exposed to direct cosmic radiation. Tuberculous mice exposed to cosmic radiation at high altitude under 10 cm of lead showed a significantly greater mean survival time than tuberculous mice kept at sea level, exposed to direct cosmic radiation, and to cosmic radiation under 1, 2, and 10 cm of lead. The correlation analysis shows that a decreas in lung lesions is associated with an increase in survival time. The decrease in lung lesions is associated with an enlargement of the spleen. At high altitude the female showed a significantly greater number of survivors than the male. At sea level no significant difference was observed. On the average the female showed a significantly greater number of survivors. The beneficial effect of daylight with ultraviolet light on tuberculous mice was manifested in a lower maximum of mortality and in a significant decrease of lung and spleen lesions. (auth)
