The response of pig erythrocytes to thermal stress

The response of the pig erythrocytes exposed either to the action of a single temperature or to two different temperatures was investigated. The cells exposed to single heating indicated an increase of osmotic resistance with increasing temperature. The effect of two different temperatures depended on the time of incubation and the second temperature employed. In a step-up and step-down heating a sensitization to a second heating occurred during the first hours of incubation. We suggest that erythrocytes after prolonged incubation can adapt to thermal stress.
