副乳癌的诊断和治疗(附12例报告)

我院１９７８～１９９６年共收治副乳癌１２例，占同期收治的乳癌１０６５例的１１３％。１２例中，男性副乳癌１例，占同期收治男性乳癌１７例的５８９％。副乳癌多发生于腋下或腹股沟处，这些部位邻近腋窝或腹股沟淋巴结丰富的区域，发生转移较早，预后较差。本组患者５年生存率为３６３７％，明显低于乳癌术后的５年生存率４５８３％（Ｐ＜０．０５）。     

东莨菪碱对大鼠下丘脑室旁核精氨酸升压素的影响

目的 观察东莨菪碱对大鼠下丘脑室核精氨酸升压素的影响。方法 以不同浓度Ｓｃｏｐ推挽灌流大鼠下丘脑室旁核 结果 扣留出液中精氨酸升压素含量随推挽时间延长而增多。结论Ｓｃｏｐ可促进ＰＶＮ释放内源性ＡＶＰ，这对了解Ｓｃｏｐ抗休克的机理有重大的意义。     

原发性贲门失弛缓症的外科治疗(附10例报告)

作者对10例原发性贲门失弛级症进行手术治疗．采用Heller术8例，食管下段贲门切除术3例，其中再手术3例，附加幽门成形术4例。本组资料表明，Olsen分期Ⅰ～Ⅲ期行Heller术效果满意，不需附加手术，Ⅲ期需行食管下段贲门切除术。作者对手术方法、手术径路、附加手术与手术效果的关系等进行探讨。     

表皮生长因子受体在人十二指肠溃疡的表达

采用免组化法检测了１１１例人十二指肠球部活检标本的表皮生长因子受体（ＥＧＦＲ）表达，结果表明ＥＧＦＲ表达以粘膜上皮细胞膜肠腔面最强，上皮细胞基侧膜和粘膜肌次之，上皮细胞胞浆又次，间质和十二指肠腺也有ＥＧＦＲ表达，淋巴滤泡无ＥＧＦＲ表达。ＥＧＦＲ表达在球部溃疡和溃疡瘢良有明显增强。ＥＧＦＲ表达强度与粘膜组织炎症程度有关，与性别、年龄无关。本次研究结果提示ＥＧＦＲ与粘膜组织对炎症的适应、溃疡的愈合和组     

白内障囊外摘除术房水细菌培养的临床观察

对36例白内障囊外摘除术抽吸前房水进行细菌培养，其中16例细菌培养阳性，大多为表皮葡萄球菌，菌落的形态很小，绝大多数为10－30个／ml，无1例发生眼内炎。这提示白内障术后前房可清除少量的细菌而不发生服内感染。     

脑水肿对大鼠血脑屏障内皮细胞膜表面ICAM—1表达量的影响

采用液氮冷冻Ｗｉｓｔａｒ大鼠－侧大脑制成血管源性脑水肿模型，将大怀脑冷冻中心制成冠状面冰冻切片，运用免疫组化染色观察脑水肿组及对照组白质脑屏障内皮细胞表面ＩＣＡＭ－１蛋白表达量的变化 。     

Sustained-release theophylline-uniphyllin in nocturnal asthmatics

For a period of six months, we collected 12 cases of nocturnal asthmatics (7 males, 5 females); their ages ranged from 20 to 66 (the average age is 49). We found that administration of Uniphyllin (10 mg/kg) once a day at 6 PM could maintain the blood level of theophylline within therapeutic range at least 12 to 24 hrs. The peak expiratory flow rate of the 6 cases we collected, were significantly improved. The result of pharmokinetic parameters: 1) The average of a single dose (12 cases) is AUC (ug. hr/ml) 275.1 +/- 62. k; Kel (hr-1) 0.068 +/- 0.019; Ka (hr-1) 0.33 +/- 0.07); Tmax (hr) 6.3 +/- 1.4; T 1/2 (hr) 11.2 +/- 4.4; Clearance/F (ml/kg/hr) 37.9 +/- 9.0.2). The average of steady state (12 cases) is Css (mg/L) 5. 7 +/- 2.6; Cmax-Cmin (mg/L) 10.09 +/- 1.46.3). The average of relative bioavailability (3 cases) is 82%, 83%, 102%. However, the extent of absorption data is available for only 3 subjects. There are too few subjects to draw any meaningful conclusions about this relative bioavailability. Four cases show slight symptoms, including 1 case of dizziness, 2 cases of nausea, and 1 case gaseousness. It is suggested that the drug be administered at about 6-8 PM to coincide peak levels in the early morning in nocturnal asthmatics.
