[Effect of the functional status of the supraoptic nuclei of the hypothalamus on surface-active properties of the lungs and external respiration in the rabbit].
The surface tension of pulmonary extracts in the balance of the Wilgelmi type, respiratory volumes, elasticity and the act of respiration were investigated in 72 control and active effects on the hypothalamic supraoptical nuclei in rabbits (local infusion of acetylcholine-electrostimulation with and without adrenalectomy, bilateral electrical lesion of the nuclei). Possible peptidergic mechanisms of inducing the surface-active properties of the lung, are discussed.
