应用不麻醉鸽进行洋地黄的生物检定

自Braun与Lusky两氏在1948年报导了用乙醚麻醉的鸽进行洋地黄的生物检定后,因具有操作简便、动物易于获得而又经济,及实验精密度较猫法为高等优点,已先后被各国药典收载成为法定的检验方法。中国药典1953年版第一增补本亦采用了鸽法。其他含强心甙的毒毛旋花子类植物药亦以鸽法进行效价测定。但此法须用乙醚作麻醉剂,而武汉地区夏季室温常在37°左右,使实验进行很困难。我们注意到鸽子性情温和,是     

Superior Mesenteric Artery Compression Syndrome

An attempt was made to search the medical records of the University Hos-pital and five affilicated hospitals at Rochester, NY for the last 10 years. Seventeen patients with superior mesenteric artery compression syndrome were found. The prevalence of this disease in a chronic-care hospital (0.965/1,000 admissions) is significantly higher than that in acute general hospitals (0.0108-0.0520/1,000 admissions) byChi square statistic (P < 0.001). This syndrome should be suspected in patients with chromic wasting diseases who are bedridden and have lost weight after which they develop frequent vomiting or aspirations. On reviewing 146 cases from the literature after 1963, duodenojejunostomy was considered to be the best procedure for severe cases. The same good results were not achieved after gastrojejunostomy and lysis of the ligament of Treitz. Gastrojejunostomy provided adequate decompression of the stomach but was inadequate for releasing duodenal obstruction. Some patients after division of the ligament of Treitz had difficulty in downward displacement of the duodenum and the symptoms of obstuction persisted necessitating duodenojejunostomy.
This paper demonstrates that in two patients gastrojejunostomy failed to relieve the obstruction. Once of them had to be reoperated on and a duodenojejunostomy was performed with relief of obstructive symptoms.
