Capillary circulation in organic hemiplegia
Collapse of the lung causes: (1) collapsed lung, (2) a rise in pressure strain on the right heart, and (4) a Compression of the great veins (2) an insufficiency in the return of the heart.
a decrease in the fom of blood throughout the in the pulmonary circulation, (3) an increased reduction in the vital capacity. causes: (1) a rise in the venous pressure, venous blood, and (3) a decreased output of
Up to relatively extreme degrees of pressure these hindrances are compensated for by an increase in tone’ of the vasocoastrictor center. The first sign of the strain on this compensatory mechanism is an exaggera’tion of the Traube-Hering waves, a A time comes tendency for the peripheral resistance to give way during inspiration. when the center can no longer fully compensate, and the mean blood pressure falls below the critical level.

Qircuiation
in Organic
In the affected extremities of organic hemiplegia the following vasomotor and humoral changes were observed : (1) dilated capillaries in which there was a slower blood flow; (2) slower refilling of the capillaries after compression (20-21 seconds) than in the normal subjects (15-17 seconds) ; (3 ) diminished absorption rapacity of the capillaries and veins after compression; (4) reduction and retardation of active dilation of blood vessels after compression; (5) increased alkalinity of the blood (5.7-11 per cent) ; (6) lowering of the viscosity of the blood; (7) presence of edema and neroasphyxia due to change of tonus in the peripheral blood vessels; and (8) abnormal dilation of the vessels in the affected extremity following the injection of calcium.

Arteriogrephy of the brain is valuable from the diagnostic standpoint when the neurological findings do not indicate clearly the type and location of the brain lesion. NO reactions were noted as a result of the use of the thorotrast for arteriwwhy following the technic of Moniz. Ten eu?3ic centimeters of thorotrast are injected into the internal carotid artery after it is exposed by incision. Injection must be made quickly, and the picture must be made immediately thereafter as the thorotrast disappears from the brain after three seconds. 5. IK.
