轻、中度精神发育迟滞儿童的中药和行为干预综合治疗探讨

采用中药与行为干预综合治疗的方法对１４０名轻、中度精神发育迟滞的儿童进行分组康复观察。结果发现中药加行为干预组治疗后智力商数（ＩＱ）及能力的变化最大，明显优于单用中药组和单纯行为干预组（Ｐ＜０．０１）；与对照组相比有非常显著的差异（Ｐ＜０．００１）。从而为精神发育迟滞儿童的康复治疗提供了新的途径。     

急性重复性缺氧小鼠脑组织中儿茶酚胺类神经递质含量变化的研究

用高效液相-电化学检测器测定急性重复性缺氧小鼠脑组织中DOPA、DA、NE和Ep等儿茶酚胺类物质的含量。结果发现:与空白对照组(A组)比较,缺氧1次的实验对照组(B组)及急性重复缺氧4次实验组(C组),随缺氧次数增加,小鼠脑组织中的DA含量显着上升(P<0.01),NE、DOPA含量明显降低(P<0.05或<0.01);A组与急性重复4次缺氧后饲养2d的实验对照组(D组)小鼠脑组织中儿茶酚胺类含量接近,没有统计学意义(P=23.77).结果提示脑组织中儿茶酚胺类物质可能参与急性重复缺氧小鼠的耐缺氧能力的形成,而且是一个可逆的快反应。     

三波长分光光度法测定复方甲基炔诺酮片中有效成分的含量

复方甲基炔诺酮片为含甲基炔诺酮(0.3mg/片)和炔雌醇(0.03mg/片)的糖衣片,对其有效成分含量的测定已有比色法、高效液相色谱法、导数分光光度法、荧光法及正交函数法。本文用三波长分光光度法消除组分间的相互干扰,对甲基炔诺酮和炔雌醇的含量进行测定,操作简便。     

氨氯地平与尼群地平治疗高血压的多中心平行对照研究

采用多中心、随机、单盲、组间、平行对照的方法对488例原发性高血压患者进行氨氯地平或尼群地平4周治疗观察，显示氨氯地平的降压有效率为90．4％，较尼群地平显著为高。不良反应较少，安全性好。每日只需服药1次，剂量5～10mg，方便病人。     

Neurogenic bladder in acquired immune deficiency syndrome (AIDS).

This is the first report of incidence of neurogenic bladder in patients with acquired immune deficiency syndrome (AIDS) and emphasizes that it is a significant cause of various voiding dysfunctions in these patients. Neurologic disease occurs in about one third of patients with AIDS. Both central and peripheral nervous systems may be involved. Urodynamic evaluation is necessary for assessment and management of neurogenic voiding disorders in this group of patients.     

大黄对实验性糖尿病大鼠肾脏肥大及高滤过作用的影响

肾脏肥大和高滤过是糖尿病肾病出现最早的病理生理特征。本研究利用中药大黄抑制糖尿病的肾脏肥大,试图达到控制其高滤过现象。实验结果表明,大黄能明显地抑制糖尿病肾脏肥大及其组织中蛋白质、DNA含量的增加;大黄治疗组的菊粉清除率明显低于非治疗组;此外,大黄还能使糖尿病血清甘油三酯、胆固醇水平降低。结论:大黄可以通过影响糖尿病肾病肾脏肥大,降低高滤过和纠正血脂代谢紊乱,治疗实验性糖尿病肾病动物模型。     

天然有机分子精细立体结构规律的初步研究Ⅱ．影响熔点的结构因素

应用Ｘ衍射方法测定雷公藤两个化合物的晶体结构，并对影响固体熔点的结构因素进行分析。晶型（或空间对称群）、结晶溶剂、分子间作用力及分子构象的精细变化均可导致晶态物质的熔点变化。     

Malignant melanoma metastatic to the stomach: upper G-I endoscopic finding--report of a case

a 54-year-old male was presented with huge, black, ulcerative and painless tumor of the sole of left foot. Malignant melanoma was proved by biopsy, but patient refused any treatment. He visited our hospital again when bloody vomitus was noted two months later. Chest P-A revealed multiple lung metastases, and marked liver metastasis was also found by abdominal echo. Upper gastrointestinal (UGI) panendoscopy revealed multiple melanotic nodules with ulcerations at the tip, scattering diffusely on the fundus and upper body of the stomach. Metastatic malignant melanoma was proved by endoscopic biopsy. Metastatic tumor of the stomach was rare, and the endoscopic finding of the malignant melanoma with gastric metastasis was more rarer in the literature in Taiwan. So we would like to present the very rare finding of the endoscopy.
