Ether anesthesia significantly elevates 11-oxycorticosteroids (11-OCS) and damages lymphoid tissue in rats. Halothane anesthesia, however, does not induce these stress responses, highlighting the adrenal cortex's role.

Area of Science:

Endocrinology
Immunology
Anesthesiology

Context:

Investigates the physiological stress responses to different anesthetic agents.
Compares hormonal and morphological changes in lymphoid tissue.
Examines the role of the adrenal cortex in stress response.

Purpose:

To quantitatively compare the effects of ether and halothane anesthesia on 11-oxycorticosteroids (11-OCS) levels and lymphoid tissue morphology.
To elucidate the stress-inducing potential of different anesthetics.
To determine the involvement of the adrenal cortex in mediating these responses.

Summary:

Ether anesthesia significantly increased circulating 11-OCS levels and caused substantial lymphoid tissue degeneration in rats.
Halothane anesthesia did not produce significant changes in 11-OCS or lymphoid morphology, indicating it is not a stressor.
