Studies on the Oxidation - Reduction of Hemo
The apparently spontaneous conversion of hemoglobin to methemoglobin is an occurrence that has been recognized ever since the discovery of the latter blood pigment (Hoppe-Seyler, 1864). Although certain bacteria can oxidize hemoglobin to methemoglobin, the alteration of hemoglobin observed by the chemist is probably rarely due to bacterial action. Indeed, this conversion can occur in the comple...

This work represents an attempt to confirm reported observations of a juxtamedullary by-pass in the kidneys of animals subjected to various physiologic procedures and to shock. Rabbits injected with epinephrine, pitressin, renin and hypertensin, made hypotensive by bleeding and inhalation of amyl nitrite, and after stimulation of one sciatic nerve, were injected with india ink.

متن کاملStudies of the Pulmonary Circulation
The question of whether or not the blood-vessels of the pulmonary circulation are under the control of the central nervous system has been a subject for difference of opinion for many years. Several years ago I published ( I ) the results of some experiments bearing upon this problem, which led me to a belief in the existence of a vasomotor supply to the lesser circulation. Since then I have ca...
متن کاملIndicator-dilution studies with "diffusible" indicators.
• The indicator-dilution principle has been applied to studies of the circulation in order to provide estimates of flows and volumes in the vascular compartment. A sine qua non of validity of these estimates is that the indicator used remain within the confines of: the vascular compartment for the entire duration of the period required to obtain appropriate samples of blood. In such a symposium...
متن کاملRadio-potassium indicator-dilution studies during angiocardiography.
In an attempt to learn more about the physiologic changes in the cardiovascular system during angiocardiography and the nature of mixing of radio-opaque dyes with blood, radiopotassium and Diodrast I' dilution curves were obtained before and during angiocardiography. Studies in patients without valvular disease and with mitral valvular disease indicated an increased cardiac output during angioc...
