| sensitization to heat by x-rays. | 1. paramecium caudatum is sensitized to heat by sublethal dosages of x-rays. thus if paramecia are irradiated, then exposed to a sublethal dosage of heat they are killed, but if the same heat exposure precedes the same dosage of radiations, they are not. 2. sensitivity to both heat and x-rays is much greater in paramecia from the log growth phase than in those from the stationary phase of a culture. 3. recovery from heat sensitization in animals from the stationary phase of a culture is slow, re ... | 1948 | 18920613 |
