Normal Heart Weight/Body Weight (HW/BW) and Left to Right Ventricular (L/R) Ratios for Rabbits.

Abstract

RATIOS 409relatively weak ones ( 1 hour each) from a General Electric S.l lamp were given it was observed that the short intense irradiation did not affect the preparation deleteriously and thus the responses to the weak, long irradiations exhibited the same effect as was noted to be the case when short, intense irradiations were employed.2. Several hearts were immersed in cool (12-14°C.) Ringer's solution until they ceased beating. These were then irradiated and they started to beat after from one to 10 minutes of irradiation. On one heart this irradiation procedure was carried on for a period of 70 hours.
