EFFECTS OF GASTRIC FREEZING ON THE ISOLATED DENERVATED GASTRIC POUCH IN DOGS.

The purpose of this study was to investigate the effects of gastric freezing on the chief and parietal cells of the stomach. To carry this out six Heidenhain pouch dogs were prepared. The secretions of these pouches were studied, both for HCl levels and pepsin activity, for 30 days before and 30 days after the freezing of the pouch. Freezing was carried out for one hour at -17 to -20 degrees C. The results show that no essential depression of either the HCl levels or the pepsin activity of the juice was effected by freezing. Therefore, it is deduced that freezing does not affect the functional activity of either the chief or the parietal cells. Complications such as ulceration and fistula formation into adjacent organs occurred as a result of freezing in certain pouch dogs.

Useful measures in the prevention of deep vein thrombosis in the legs.

THE THREE PROBABLE FACTORS INVOLVED IN DEEP VENOUS THROMBOSIS ARE: (1) stasis, (2) alteration in the endothelium of the veins, and (3) alteration in the clotting mechanism of the blood.Control of stasis is assisted by elevation of the foot of the bed and by the use of washable elastic stockings and early ambulation, together with foot exercises. To prevent damage to the endothelium of the veins during operation, the heels should be elevated off the operating table by means of a small rolled towel in order to take weight off the calf muscles. The use of elastic stockings demonstrated in diagrams and some of the fallacies in connection with their use are outlined.
