[The contractile activity of the lymphatic vessels in rats after head-down tilt exposure].
After antiorthostatic attitude of rats during 12 days, the contractile activity of their isolated lymphangions of the thoracic duct was studied. The amplitude of contractions was found to be decreased as well as the effects of serotonine, histamine, and acetylcholine, whereas that of adrenaline increased. The latter finding suggests enhancing of the activity of lymphatic vessels' adrenergic structures in antiorthostatic.
