A marked increase in blood flow, determined by means of the plethysmographic method, was usually observed in the hand, forearm, and leg at the height of the hypoglycemic response produced by massive doses of insulin administered to seven patients with schizophrenia. In contrast, a rapid decrease in blood flow to below the control level, especially in the hand, usually occurred with the termination of hypoglycemia by the administration of glucose either orally or intravenously. When glucose was given without the previous injection of insulin, this marked effect upon blood flaw was not apparent. During the hypoglycemic state when the blood flow to the arm was increased about 2.3 times, the forearm blood showed a very significant decrease in both oxygen and carbon dioxide arteriovenous differences. From chemical changes of the same magnitude in both brain and arm blood, previous workers have concluded that there was no significant change in cerebral blood flow during the hypoglycemic state. Therefore, the necessity for obtaining blood flow and chemical changes simultaneously was stressed by the present authors. ROTH. Cossio, P., and Berconsky, in Increased Size of Stenosis. Rev, argent.

Extremities in Mitral
Measurements of the venous pressure by the direct method were made in the antecubital vein and in the femoral vein in thirteen patients with mitral stenosis. These measurements have shown that a circulatory stasis exists in the territory of the superior vena cava due to reduction of its caliber and modification of its course as a consequence of the heart’s rotation and of the change in orientation of the aorta, which occur in mitral stenosis. The cyanosis of the face and hands and the jugular engorgement so common in mitral stenosis even without cardiac insufficiency are related to this stasis in the territory of the superior vena cava. A new and simple model of syringe is described which makes easier the determination of the venous pressure by the direct method. AUTHORS. Williams, Nephritis.

Fifteen cases of acute glomerular nephritis have been followed with serial electrocardiograms. Changes were observed in ten cases and consisted chiefly in flattening and inversion of the T waves in one or more leads, including the precordial lead. Changes were noted less frequently in the initial positive deflection in the precordial lead, and in the auriculoventricular conduction time. No correlation could be established between the occurrence of these changes and the signs of cardiac and renal insufficiency, but the series is too small to permit accurate deductions in this respect. Rabbits in which acute nephritis had been induced by the method of Masugi, failed to show comparable changes in their electrocardiographic patterns. AUTHOR.
