The importance of the type of the nervous system in the body's response to injurious factors

Summary

The experiment was performed on 5 dogs-3 with a strong and 2 with a weak type of nervous system. A number of general reactions of the organism during inflammation caused by subcutaneous administration of turpentine (0.1 ml) were studied. A greater degree of hyperthermia, a higher ESR and changes in the leucocytic formula (eosino-and leukopenia) were noted in the dogs of the weak type in comparison with those of the strong, especially of the strong and inert type of nervous system. In ACTH administration (20 units) to the same dogs and to 5 other animals-3 with a strong nervous system type and 2 with a weak type-eosino-and lymphopenia were also most pronounced in dogs with a weak type of nervous system, and least marked in strong, inert animals. A shift to the left in the neutrophilic group of leucocytes was also most pronounced in weak dogs. The data obtained indicate a different degree of activity exercised by various physiological systems, including the endocrine system, in animals with different types of nervous system.
