The intricate secretory mechanisms of the normal pancreas maintain homeostasis in the human by their harmonious oontribution to the endocrine and exocrine systems of the body. These systems directly reflect any deviation from normal pancreatic function. [...]

Cancer is almost as old and pervasively present as life itself. Its toll has mounted relentlessly through recorded history, and its claim of human life to-day is second only to circulatory diseases. The word cancer is Latin for 'crab'. [...]

Studies of small bowel physiology in man were few until twenty five years ago. Progress in this field of study was hindered by difficulties in methodology. The inaccessibility of the organ, the difficulties in obtaining samples from its lumen and the complexity of the interelation of its main functions accounted for this fact. [...]

The present study was undertaken to evaluate the effects of both carbohydrate and protein rich meals on the cardiodynamics in men at rest and during exercise. Heart rate, oxygen consumption, arterial pressure and cardiac output were measured in twenty-four fasting men at rest and during exercise. [...]

The science of extracorporeal circulation is very new. This past decade has witnessed the introduction and subsequent development of temporary extracorporeal circulation as a routine surgical technique which permits the cardiovascular surgeon to repair otherwise incurable lesions in and around the heart. Since the inception of these techniques a great deal of attention has been focused upon problems relating to blood oxygenation and selection of a particular pump with minimum biological effect on the circulating blood. [...]

Constancy of the form of living cells is one of their most important psysiological characteristics. This is possible only when intracellular and extracellular osmotic pressure is constant. Equal osmotic pressure between the two sidas of cell membranes is provided by the so-called pump mechaaism(s) of ion movements. [...]

Cardiogenic shock is the syndrome of acute circulatory collapse secondary to myocardia1 infarction. This type of shock is responsible for much of the overall mortality of acute coronary artery occlusion especially in the younger age group. [...]

The word "Pituitary" is derived from the Greek - pituita, meaning mucus or phlegm (1). In Galenic times (131 - 200 A.D.), it was thought that a by-product of animal spirits passed through this small body and filtered down through cribriform plate into the nose. [...]

The view that cardiac output is the prime determinant of maximal oxygen intake has been discussed in the medical literature for some time (13, 61). The proposition was challenged by subsequent investigators (7, 30, 82) who, in agreement with Bock et al (23), claimed that 'peripheral factors' in terms of local blood flow and various changes at the muscular site were limiting maximal oxygen intake. [...]

During the past fifty years several investigators have attempted to develop a practical means of removing the retention products in cases of renal insufficiency. Three main methods have been investigated: (1) peritoneal lavage, (2) extracorporeal dialysis of blood, and (3) intestinal lavage, but there are few experimental studies to demonstrate the gastrointestinal excretion of creatinine.
