从肝论治头痛

头痛为中医脑病科的常见病、多发病。中医学认为,内伤头痛在生理病理上与肝关系密切。笔者试从肝论治内伤头痛,若肝气郁滞者,治以疏肝理气之法;肝血瘀阻者,治以活血通络之法;肝阳上亢者,治以平肝潜阳之法;肝血亏虚者,治以养肝补血之法;肝肾亏虚者,治以培补肝肾之法。并举临床验案1例,以资佐证疏肝活血的具体运用。     

羊肠线的研究 (一)灭菌方法的初步研究

使用紫外光灯在一定时间及一定距离内照射羊肠线,可以提高羊肠线的无菌率。利用化学药品消毒有的文献上说是完全不可靠的,但是我们的实验指出,化学药品对羊肠线有显著的清毒作用。加热法一向被认为是羊肠线唯一可靠的消毒方法,但是我们的实验指出,加热法如果不在良好的化学药品消毒和无菌操作的配合下也不能制得绝对无菌的羊肠线。     

醇对SDS-CTAB-H2O体系双水相性质的影响

研究了短链一元醇(乙醇、正丁醇)和二元醇(乙二醇、1，4—丁二醇)对正负离子表面活性剂混合溶液(十二烷基硫酸钠—十六烷基三甲基溴化铵—水)双水相的影响。结果表明：一元醇的加入不但缩短了双水相的成相时间、使原水溶液双水相的区域得到扩展而且还会导致新双水相区域的出现，这种影响随着醇类链长的增长而增大。而二元醇的加入对双水相的相图影响不大，只是对形成双水相的表面活性剂最低总浓度稍有影响。实验结果也表明，出现双水相的表面活性剂最低总浓度与混合溶液的临界胶束浓度(CMC)有关，但CMC并不是决定出现双水相表面活性剂最低浓度的唯一因素。     

Role of psychologic and social variables in TMJ Pain Dysfunction Syndrome (PDS) symptoms

The aim of this study was to measure the relative importance of a number of psychologic and social variables in explaining the severity of symptoms of functional disturbances of the stomatognathic system. 261 non-care seeking patients with respect to pain and dysfunction of the stomatognathic system were examined. The total sample consisted of two subgroups: Group 1 (n = 130) with a complete natural dentition and Group 2 (n = 131) wearing complete maxillary and mandibular dentures. Symptoms of functional disturbances of the stomatognathic system were assessed using two questionnaires. One was derived from the Anamnestic Dysfunction Index and the other was an extended questionnaire which included accessory symptoms frequently mentioned in the literature. The patients also completed the Hopkins Symptom Checklist, the Dutch Personality Inventory, and a Dutch form of the Minnesota Multiphasic Personality Inventory. In both patient subgroups symptoms of functional disturbances of the stomatognathic system were significantly correlated with patient's sex and a complex of highly intercorrelated psychologic variables: psychoneurotic- and somatic symptoms, neuroticism, negativism, and somatization.     

高效液相色谱法与微生物法测定血清乙酰白霉素的比较

目的:寻求一种准确度和灵敏度高、重现性好的乙酰白霉素血药浓度高效液相色谱(HPLC)测定法。(?)建立HPLC测定乙酰白霉素方法,然后以志愿男性口服乙酰白霉素颗粒剂后采取血样为研究样本,同步用微生物法和HPLC进行测定比较分析。结果:建立的HPLC色谱图:乙酰白霉素标准液与经活性碳处理乙酰白霉素口服颗粒剂甲醇液在231nm波长下,均呈现8个组分,血清药物和血清空白色谱图显示有某些杂质可干扰A_9和A_8,其他组分同标准药物色谱图。试验方法的线性关系良好,不同标准浓度与乙酰白霉素主要组分A5峰高的r=0.9996;药物浓度在0.026～3.0μg/ml范围内与A_5峰高呈直线关系;平均回收率96.43％,实际最小检测量0.02μg/ml,变异系数(CV):药物浓度在0.5与1.5μg/ml时,CV_(批内)为4.75％与5.80％,CV_(批间)为6.42％与6.70％。微生物法:线性关系:不同浓度标准液与抑菌圈直径的r为0.9986,药物浓度在0.06～2.00μg/ml范围内与抑菌圈直径线性关系良好;最小检出量0.06μg/ml;CV为5.07％～8.8％。结论:HPLC乙酰白霉素血药浓度测定法准确度与灵敏度高,重现性良好的试验方法。
