The antibacterial component from Cinnamomi Cortex against a cariogenic bacteriumStreptococcus mutans OMZ 176

The methanol extract of Cinnamomi Cortex showed antibacterial action against cariogenic bacterium,Streptococcus mutans OMZ 176. The active principle of the extract was identified to betrans-cinnamaldehyde, which was bactericidal in the minimal inhibitory concentration (MIC) of 100 μg/ml againt the strain. From the results of antibacterial activity of cinnamaldehyde and its derivatives, the acrolein group in the cinnamal-dehyde was elucidated to be an essential element for the activity.     

羊心淋巴流阻断后血清生化指标的改变

为给临床心脏术后监测心淋巴管损伤程度及可能出现的并发症提供参考指标，以手术方法阻断羊心淋巴流并对其血清相关成份进行了测定。实验发现，实验组术后谷草转氨酶（ＳＧＯＴ）、谷丙转氨酶（ＳＧＰＴ）、碱性磷酸酶（ＡＫＰ）、乳酸脱氢酶（ＬＤＨ）均有不同程度的增高，以ＳＧＯＴ增高最为明显，术前均值为４７．５３Ｕ，术后２天增至１０４．２０Ｕ，高峰出现时间最早，多在术后２４小时。血清离子改变中低钾最为突出，血钾在术后２天明显降低（Ｐ＜０．０１），术后７天逐渐恢复，术后１４天恢复至术前水平。血清蛋白改变以球蛋白降低、白蛋白／球蛋白比值升高为主。提示心淋巴循环郁滞可导致心肌细胞损伤、毛细血管通透性和结构的改变。不同酶活性的变化对郁滞的敏感度存在着差异。

综合医院心理咨询门诊儿童咨客分析

目的；了解综合医院心理咨询门诊儿童咨客的特点。方法：总结中山大学附属三院心理咨询门诊近3年儿童咨客的资料。结果：咨客男女比例为1．96：1，咨客人数随着年龄的增长而增加，女童中13－16岁的比例男童大，5－8岁和9－12岁的比例较男童小。广州市内外的咨客比例为1．38：1，不同年龄儿童咨客的居住地构成是有差异的。最常见的病种是精神分裂症，神经症、精神发育迟滞，儿童多动症，单纯咨询和品行障碍，不同年龄，不同性别的儿童咨客的疾病构成是有差异的。结论：综合医院心理咨询门诊与儿童心理咨询门诊的儿童咨客是有差异的。     

Circular stereotactic callosotomy: A preliminary report

Summary The authors propose a new method for performing Stereotactic callosotomy, which they have named circular callosotomy. The operating device is the original Riechert-Mundinger's string electrode, which can be protruded through a side window and by rotating the probe it is possible to cut the commisural pathways to the extent required. The anatomical results of the operation can be checked using MRI scanning.

Effects of beta 1- and beta 1 + beta 2-antagonists on training-induced myocardial hypertrophy and enzyme adaptation

The effects of beta 1- and beta 1 + beta 2-antagonists on the myocardial adaptation to exercise training were investigated in male Sprague-Dawley rats randomly divided into trained (treadmill, 1 hr/day, 5 days/week for 10 weeks at 27 m/min, 15% grade) without drug (TC), sedentary without drug (SC), trained treated with atenolol (TA) (10 mg/kg body wt, i.p.), trained treated with propranolol (TP, 30 mg/kg body wt, i.p.), and sedentary propranolol. Doses of both beta-antagonists were titrated to decrease the exercise heart rate by 25% compared to the controls. The heart weight and heart/body weight ratio were significantly greater in TC (1.28 +/- 0.07 g (P less than 0.01); 296 +/- 12 mg/100 g body wt (P less than 0.05) respectively) than in SC (1.09 +/- 0.04 g and 268 +/- 11 mg/100 g body wt), or in TP and TA. Myocardial mitochondrial protein was unchanged by training or beta-blockade. Citrate synthase and beta-hydroxyacyl CoA dehydrogenase activities were not altered. Carnitine palmitoyltransferase activity was increased in SP compared to SC. Training increased hexokinase activity only in TC (5.22 +/- 0.12 vs 4.26 +/- 0.23 mumol/min/g wet wt, P less than 0.01). Lactate dehydrogenase activity increased significantly (P less than 0.01) in both TC (383 +/- 14 mumol/min/g wet wt) and TA (372 +/- 14 mumol/min/g wet wt) compared to SC (276 +/- 14 mumol/min/g wet wt), but not in TP versus SP. These data indicate that (1) beta-adrenergic blockade prevents training-induced cardiac hypertrophy; (2) beta-antagonists have little effect on the myocardial oxidative capacity; and (3) while the training induction of myocardial hexokinase is inhibited by both beta 1- and beta 1 + beta 2-antagonists, myocardium may increase its ability to utilize lactate during exercise with training despite beta 1-blockade.     

在"医学教育国际标准研讨会"开幕式上的讲话

本次会议对经济全球化时代尤其是加入世界贸易组织之后,全面提升中国医学教育水平和质量,提高中国医学教育国际合作与竞争能力,具有十分重要的意义.要在国际竞争中立于不败之地,中国的高等医学教育必须增强紧迫感和危机感,加强国际交流与合作,加速高等医学教育国际化进程,积极研究并学习和借鉴医学教育国际标准,加快改革与发展,全面提高中国高等医学教育的综合实力.医学教育国际标准的引入,为我们重新审视和制定我国医学教育质量标准提供了十分有价值的参考.
