SIMULTANEOUS RESPIRATORY EXCHANGE AND BLOOD SUGAR TIME CURVES

Simultaneous Respiratory Exchange and Blood Sugar Time Curves Obtained in Diabetic and Non Diabetic Individuals following Ingestion of Glucose.

Blood Sugar Time Curves.

Stimulation of the Sugar-regulating Mechanism as Shown by Duplicate Blood Sugar Curves.*

After the oral administration of glucose, when the concentration of the sugar in the blood is falling, ingestion of a second dose of glucose may result in little or no increase in blood sugar. This occurred in nine out of thirteen experiments conducted by Foster (1). Maclean and de Wesselow (2) had previously reported a single case in which a second dose of glucose produced a curve which was ne...

Ammonia and Blood Sugar

In 1919 Fosse (6) showed that urea is formed by the oxidation of solutions containing such amounts of glucose and ammonia as are present in the blood. Recently Hynd (9) found that “A 2 per cent solution of glucose containing approximately 60 mg. NH3 showed no optical change at room temperature, but after 24 hours at 50” the rotation fell from +0.87” to +0.29” . . . . Similar results were obtain...

Respiratory Physiology: Gas Exchange and Respiratory Mechanics

Respiration provides oxygen (O2) and removes carbon dioxide (CO2) for the body. An extraordinary anatomic arrangement of functional units (the alveoli) delimited by extra-thin walls (epithelium and endothelium) creates the interface for gas exchange between air and blood. Repetitive expansion and collapse of the chest wall facilitates movement of gas in and out of the lungs. This review focuses...
