title: [A study on expression of the heat shock suppressed gene in distal organs of rats after scalding].
abstract: In order to address the question whether stress in intact higher animals may induce cellular heat shock response in distal organs, the inhibition of normal gene expression was studied on the basis of our previous findings about the induction of heat shock proteins in liver and brain of rats after scalding. Male SD rats were scalded on the back, 10-240 min thereafter decapitated, and the heat shock suppressed gene-1 was quantitated by dot blotting. The results showed that gene-1 decreased rapidly after scalding in both the organs, and did not recover to control levels even 240 min after scalding. The decrease of gene-1 went parallell with the severity of scalding. Thus it may be concluded that stress may induce heat shock response of distant organs in intact animals. Possible pathological significance of these findings was discussed.
