[Appraisal and significance of individual reactivity, daily and seasonal fluctuations of biorhythms, age, sex, and force and multiplicity factor of mechanical effects in the development and outcomes of the shock process].

Experiments were conducted on 944 rats on two models of traumatic shock (prolonged crushing of soft tissues of the thighs, shock after Cannon). A diagnostic index of the severity of traumatic shock (K) was elaborated which showed in conditional units (from 0 to 9) the relation of changes of the skin electric resistance before and after the trauma. The types of the animals' responses were determined and classified according to this index.
