The authors have studied the influence of endogenous norepinephrine released during exercise on the level of serum gastrin. After a period of absolute rest, 10 volunteers in good health underwent a prolonged graded exercise corresponding to 60, then 80% of the maximum theoretical heart-beat frequency. Only norepinephrine was significantly high during the course of the second phase of muscular activity. No significant change in serum gastrin was observed during the entire test.

Renal amylase clearance in relation to creatinin clearance (Cam/Ccr) was determined for 20 patients suffering from acute pancreatitis (AP). For each of them, the diagnosis rested upon operative or laparoscopic observation of characteristic anatomical or histological lesions. The average clearance relationship in these patients reached 16 +/- SEM 3.8%. These results were significantly higher than those obtained from 132 patients who had been hospitalized for other medical or surgical diseases, as well as from 51 test patients (p less than 0.001). The authors stressed the diagnostic importance of this test, in particular in the presence of a normal amylasemia level.

Partial venoarterial bypass with return of oxygenated blood to the femoral artery can produce mixing in the aorta of the blood from the oxygenator and left ventricular sources at flow rates of less than 50% of the total body flow. This was observed in six anesthetized sheep with normal lungs maintained on controlled ventilation on partial cardiopulmonary (venoarterial) bypass. The evidence of mixing increases with the extracorporeal flow rate, reaching the aortic arch in a majority of cases at the higher rates. Management of bypass and the interpretation of its effects depend on definite knowledge of the presence or absence of mixing. Partial bypass will raise the arterial oxygen tension (Pao-2) of the blood continuing to flow through the lungs. This effect is independent of mixing (Pao-2) and may be related either to the addition of oxygen to the blood or to an enhanced pulmonary ventilation-perfusion relationship.
