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. [...]

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. [...]

An understanding of the total blood supply of malignant tumours is of fundamental importance not only to the surgeon interested in chemotherapy, but also to the radiotherapist and the medical oncologist. This is because the effect of cancericidal agents depends to a great extent upon the amount of agent delivered directly to the tumour cells within the tumour. [...]

Early in 1965, a series of patients underwent cardiopulmonary bypass for valve replacement (table 1). Prior to this time, there had been no undue incidence of cerebral complications associated with this procedure. However, the first four of these patients demonstrated severe brain damage with status epilepticus when anasthesia was reversed. All but the last case expired shortly thereafter. [...]

Gastric secretion has been studied by many investigators since the pioneer days of Pavlov. The control and regulation of gastric secretiob has been the subject of intense study. The results of previous work have shown that the gastric glands are controlled by a variety of regulating mechanisms. The main features being the nervous control by parasympathetic nervous system, the mechanical and hormonal factors in the stomach itself. [...]

Cancer of the stomach is the most frequent of all malignant growths. Livingston and Pack in 1939 (121) have stated: "There are more deaths from cancer of the stomach than from all malignant tumors of lip, tongue, cheek, tonsil, pharynx, larynx, salivary glands, thyroid, male and female breast, ovary, uterine cervix and corpus uteri combined." [...]

Through the ages, coronary artery disease has been plaguing mankind by the millions every year. Many sudden mysterious and dramatic deaths were attributed to this disease, yet people did not know how it worked. It was only during the advent of the 20th century that medical science began to probe this mystery, especially these last 35 years. [...]

Gastric secretion has been a subject of intensive investigation by a veritable army of investigators for well over a hundred years. The major stimulus for this work originated with the astute observations and pertinent experiments of the American Army Surgeon, William Beaumont, on the French Canadian lumberjack, Alexis St. Martin, in the early nineteenth century.

This thesis represents the result of one year's work in the Department of Experimental Surgery. The present studies were designed to study the long term effects of radio-strontium (Sr89) in rats and the hormonal factors affecting it. At the time our studies were started there was no published data on the effects of hormones on the tumors produced by radioactive strontium and the complete histological appearance of these tumors. During the course of this year we have also studied the effect of parathyroid extract on the metabolism of radiostrontium.

Homotransplantation or homografting is the transfer of tissue and organs from members of a species to other members of the same species. The "species" is the characteristic background of homotransplantation.
