口服二巯基丁二酸治疗狗路易氏剂中毒

为证实口服二巯基丁二酸（ＤＭＳＡ）治疗路易氏剂中毒的效价，以狗为实验动物，进行实验治疗研究，狗口服ＤＭＳＡ（４０～１２０ｍｇ／ｋｇ）后，２周内未见到有关的生理，生化指标明显变化，该药毒性较小。ＤＭＳＡ可在肠道内较好地被吸收，与静脉注射途径比较，口服组血药浓度上升慢，下降亦慢，可在体内维持较长时间，ＤＭＳＡ在体内促排砷的作用与静脉注射同剂量ＤＭＳＡ（钠盐）相当。狗口服ＤＭＳＡ４０ｍｇ／ｋｇ可对抗路易     

Effect of shenmai Injection on SIL-2R NK and LAK cells of patients with advanced carcinoma

Serum interleukin-2 receptor (sIL-2R) level, activities of natural killer cell (NK) and lymphokine activated killer (LAK) cells were determined in 60 patients with advanced carcinoma (AC) before and after treatment with Shenmai Injection (SMI), forty healthy persons were taken as non-carcinoma control (NC). The results showed that: Serum sIL-2R level in AC were much higher than those in NC (P<0.05) and activities of NK and LAK cells in AC were much lower than those in NC (P<0.05) before treatment. There was no significant difference among gastric, colonic and lung cancer (P>0.05). After treatment with SMI, it was found that the level of sIL-2R in all patients were obviously lowered (P<0.05) while the activities of NK and LAK cells were signifficantly higher than that prior the treatment (P<0.05). Relevancy was not found between sIL-2R and NK, LAK cells. These data suggested that the immune function was compromised in AC, and SMI has a wide effect of immuno-regulation.     

悬雍垂保留在悬雍垂腭咽成形术中的作用

目的 探讨悬雍垂保留在悬雍垂腭咽成形术(UPPP)中的作用。方法 比较43例UPPP与43例保留悬雍垂的改良UPPP的术中术后并发症、术后症状改善程度以及术后咽腔测量结果。结果 术中术后大出血、开放性鼻音、进流食返呛人鼻腔等并发症：改良UPPP明显低于UPPP(P＜0．05)；咽异物感：改良UPPP极明显低于UPPP(P＜0．01)。术后1年患者主观症状改善程度：明显改善者，改良UPPP高于UPPP，无改善者，UPPP高于改良UPPP，有显著性差异(P＜0.05)。术后1年咽腔扩大程度：下腭咽横径、前后径，改良UPPP较UPPP两者均明显扩大(P＜0.05)。结论 UPPP中保留悬雍垂可明显降低术中术后大出血、开放性鼻音、进流食返呛人鼻腔、咽异物感等并发症，术后症状明显改善，咽腔得到明显扩大。     

A study on various symptoms of chronic hepatitis treated with radix astragali and its regulative effect to levels of serum hormone

Sixty-seven cases of chronic hepatitis were treated with Radix Astragali. After treatment (2-month course), the clinical improvement rate in 38 cases of the Stagnation of the Liver-Qi and Deficiency of the Spleen type was 92.1%, and in 26 cases of the Deficiency of Liver Yin and Kidney Yin type was 88.5%, more effective than in the control group (P<0.05). The regulative effect to the levels of serum hormone was observed in the patients of the Stagnation of the Liver-Qi and Deficiency of the Spleen type treated with this medicine. The results showed that the levels of serum triiodothyronine, estradiol (female) and testosterone (male) were increased after treatment (1.40±1.38 ng/dl, 129.30±1.23 pg/ml and 496.24±1.47 ng/dl). Pre-treatment levels were 1.22±1.49 ng/dl, 104.60±1.45 pg/ml and 398. 17±1.55 ng/dl respectively (P<0.05); however, the level of serum prolactin (2.75±4.46 ng/ml) was lower after treatment than before treatment (3.20±3.82 ng/ml,P<0.05). No obvious changes were observed in the levels of serum follicle stimulating hormone, luteinizing hormone, thyroid stimulating hormone, thyroxine, triiodothyronine uptake ratio and cortisol after treatment.

新抗喘药物的研究——茶碱衍生物及卤代苯乙醇胺化合物的合成

本文根据β_2-受体兴奋剂和茶碱类药物的作用机制,结合两类药物的基本结构和构效关系,运用新药设计中的拼合原理及生物电子等排原理,设计扦合成了两类共十六个尚未见于文献报导的化合物。经初步药理实验证明均具有抗哮喘作用,其中I_(5-8)活性较高,且对心脏副作用轻微,可望成为治疗哮喘的新药。     

头孢氨苄缓释片在健康人体内的生物利用度和药物动力学

目的:比较头孢氨苄缓释片和普通胶囊的生物利用度和药物动力学。方法：10例健康志愿者分别单剂量口服500mg头孢氨苄缓释片和普通胶囊，血药浓度测定方法为HPLC法。结果：两种剂型体内过程均符合一室开放模型，缓释片的达峰时间（Tmax）为（2．58±0．59）h，峰浓度（Cmax）为（10．08±1．68）μg／ml．吸收速率常数（Ka）为（0．90±0．53）／h，消除速率常数（Ke）为（0.26±0.02）／g，半衰期（T1／2）为（2.67±0.23）h，清除率（Cl）为（6.93±1.71）L／h，分布容积（Vd）为（26.66±6.72）L，药一时曲线下面积（AUC）为（48.31±9.32）μg·h／ml。两种剂型T一C一Ka、Ke、T1／2和Cl均存在显著性差异（P＜0．01），Vd、AUC无显著性差异（P＞0．05）；缓释片的相对生物利用度为（104．90±8．35）％。结论：缓释片的吸收减慢，Tmax推迟，T1／2延长，可减少服药次数，提高药物治疗的顺应性。

对２５例急性心肌梗塞（ＡＭＩ）并左心功能不全患者早期应用血管紧张素转换酶抑制剂（ＡＣＥＩ）治疗的对照性临床分析，结果：用小剂量的ＡＣＥＩ治疗对患者心率、血压无显著的影响〔治疗前后心率分别为８９．９０±１０．２２次／分与８９．４２±８．１９次／分，血压分别为１５．３７±３．４６／９．７４±２．３２ｋＰａ（１ｋＰａ＝７．５ｍｍＨｇ）〕和１４．９６±２．６０／９．４６±１．７６ｋＰａ〕；对合并轻、中度泵衰竭患者的疗效显著，但对重度泵衰竭的疗效与对照组比较无显著性差异；治疗组恶性心律失常的发生率较对照组减低１３．３８％，警告性室早的发生率治疗组较对照组减少２６．３９％，但Ⅱ°～Ⅲ°房室传导阻滞的发生率治疗组高于对照组；两组４周病死率比较无显著性差异。作者认为：ＡＣＥＩ治疗ＡＭＩ并轻、中度泵衰竭安全有效；ＡＣＥＩ有一定抗心律失常作用，但应注意传导系统的并发症，使用中应注意各种副作用的发生。     

中国蒙,汉族酒依赖与醇脱氢酶和醛脱氢酶基因多态性的相关研究

为探讨醇脱氢酶（ＡＤＨ）基因和醛脱氢酶（ＡＬＤＨ）基因多态性与酒依赖患病的相互关系，用耳血干血痕聚合酶链反应、等位基因特异性寡核苷酸探针方法，检测乙醇代谢酶ＡＤＨ和ＡＬＤＨ基因型在我国蒙、汉民族酒依赖与非酒依赖者中分布频率。结果显示在酒依赖组（汉族５２例，蒙族３１例）与正常对照组（汉族４８例，蒙族３５例）之间：汉族的ＡＬＤＨ２基因型频率与等位基因频率的分布差异有非常显著性（Ｐ＜０．０１），而蒙族则表示为ＡＤＨ２基因型频率与等位基因频率的分布差异有非常显著性（Ｐ＜０．０１）。这提示汉族酒依赖的发病与ＡＬＤＨ２基因有关，蒙族则与ＡＤＨ２基因有关。
