Character of the pulmonary circulation in experimental pulmonary edema dated by artificial ventilation

: For more than 25 years the chemistry and the function of the protein-hormonal complexes (produced by magnocellular nuclei of human and same animals) have been studied. The methods of radioimmunological analyses (RIA) for the detection of new neuropecific cardioactive protein-hormone "K" (RHK) in rat organism with myocardial ischemia has been developed. Concentration of PHK in various regions of the brain by RIA a four days after the occlusion of the carotid artery has a sharp decrease. Particularly concentration of PHK decreases 100-fold in the cerebral cortex. At the same time the level of PHK content in the blood increased from 13 +/- 0.85 to 630 +/- 3.9 ng/ml. The maximum concentration of PHK shows a sharp rise in the spleen 200-fold of their original level. This distribution pattern implies that PHK may be of importance for peripheral tissues and to the scarring in heart neurosis zone.
