Nutritional emphysema in the rat. Influence of protein depletion and impaired lung growth.

Emphysema is produced by severe food restriction in rats and is postulated to result from depletion of lung connective tissue. We studied (1) whether total dietary protein depletion worsens nutritional emphysema, and (2) whether the reduced content of lung connective tissue in nutritional emphysema results from lack of accumulation caused by impaired lung growth or by a net loss from the lung. Lewis rats weighing 200 g were restricted to one third food intake with or without protein for 6 wk.

Cardiovascular reflexes elicited by passive gastric distension in anesthetized cats.

Hemodynamic responses to passive gastric distension were examined in alpha-chloralose anesthetized cats. Gastric balloons were distended with 37 degrees C fluid at slow (50 ml/min) and rapid (250 ml/min) infusion rates before and after laparotomy. Passive gastric distension at the slow infusion rate significantly (P less than 0.

[Results of treatment of congenital hip dislocation by extensionrepositioning and Hanausek-retention].

In the past 4 years all our patients below the age of three years, suffering from luxation or dysplasia of the hipjoint, were treated only conservatively. For repositioning we used a modified overhead-extension (Extensionsreposition). The "Hanausek-Apparat" was used only for retention.
