平阳霉素治疗口腔颌面部静脉畸形的临床观察

目的观察平阳霉素治疗口腔颌面部静脉畸形的临床效果。方法160例确诊的颌面部静脉畸形患者,随机分为2组,每组80例。分别于瘤腔注射平阳霉素 地塞米松和鱼肝油酸钠。结果注射平阳霉素 地塞米松组总有效率为92.5%,治愈率为80%;注射鱼肝油酸钠组总有效率为62.5%,治愈率为42.5%。两组比较有显著性差异(P<0.01)。结论平阳霉素 地塞米松局部注射是治疗颌面部静脉畸形的一种安全有效的方法。     

浅谈牙周病预防与口腔健康教育

为更好地搞好铁路职工、家属口腔疾病防治，我们对６７７名职工、家属进行了口腔疾病的调查。结果表明，有３７４人不同程度存在着牙周病。而口腔疾病又是造成过早失牙的主要原因之一。由此可见，开展多层次的口腔健康教育，提高人群口腔健康的自我保健能力，预防牙周疾病已势在必行。     

免疫抑制鼠肾包膜下法检测口腔颌面部恶性肿瘤联合化疗敏感性的实验研究

将18例口腔颌面部恶性肿瘤做原代移植物，移植到CTX免疫抑制鼠SRC，检测了联合化疗敏感性，结合病理学观察，结果：①以对照组△TS≥－0．5omu标准，获可评价率88％（16／18）；SRC移植瘤阳性生长81．2％（69／85），零生长7％（6／85），负性生长11．8％（10／85）。②以对照组与实验组△TS（P＜0．05），移植瘤消退率≥15％为标准，68．8％（11／16）可评价药物敏感性，对PM、PVF、CVP敏感率分别为54．5％（6／11）、60％（6／10）、63.6％（7／11）。病理学证实，对照组移植瘤名存良好，实验组移植瘤有不同程度的退行性改变。③Ag－NOR计数和DNA含量测定结果，化疗敏感组与对照组之间存在显著差异。证实CTX免疫抑制既SRCA对口腔颌面部部分恶性肿瘤实现个体化疗是一简便快速方法。     

Effect of acidity of drugs on the prediction of human oral absorption by biopartitioning micellar chromatography

Biopartitioning micellar chromatography (BMC) is a potentially high throughput and low cost alternative for in vitro prediction of drug absorption, which can mimic the drug partitioning process in biological systems. In this paper, a data set of 56 compounds representing acidic, basic, neutral and amphoteric drugs from various structure classes with human oral absorption (HOA) data available were employed to show the effect of acidity of drugs in oral absorption prediction. HOA was reciprocally correlated to the negative value of the capacity factor (kBMC) determined by BMC at pH 7.4 and 6.5. The relationships between kBMC and the corresponding HOA values of all compounds were rather poor, but the correlations were improved when the acidity of drugs was taken into consideration. Moreover, the proposed models allowed obtaining of good predictive values for both highly and poorly absorbed compounds. It is demonstrated that the constructed models derived from compounds with the same kind of charge property are of more practically meaningful and rigorous.     

~(99m)Tc-Sb_2S_3胶体颈部淋巴显像及其临床评价

采用~（99m）Tc-Sb_2S_3胶体,对13例正常人及31例口腔颌面部恶性肿瘤患者进行了颈部淋巴显像。探讨了颈部淋巴显像的技术和方法,并将显像结果与淋巴结病理学检查对照研究。本方法具有安全、简便、病人无痛苦,且可重复等优点。应用其判定口腔颌面部恶性肿瘤淋巴转移的灵敏度为90.9％,特异性为80.0％,准确率为83.9％,是有一定诊断价值的检查方法。
