Effect of Chengzai Pill on the L-Type Ca^2＋ Channel Currents of Osteoblasts Pretreated with Methylprednisolone

Objective: To observe the effect of the serum containing Chengzai Pill on the L-type voltage-sensitive calcium channels current (L-VSCCsC) of osteoblastic MC3T3-E1 cells pretreated with methylprednisolone (mPSL). Methods: A control group, a model group, a low dose group and a high dose group were set up. The whole cell patch clamp technique was used to record L-VSCCsC of 10 osteoblastic MC3T3-E1 cells in each group and their peak currents were determined. Results: The peak current of the control group was 0.2284±0.0209 nA; the peak current of the model group was 0.1839±0.0179 nA; decreased by 19.5% as compared with the control group (P<0.01); the peak current of the low and high dose groups was 0.2526± 0.0093 nA and 0.2671±0.0120 nA respectively, increased by 37.4% and 45.2% as compared with the model group (P<0.01); the difference between the low and high dose groups was P<0.05. Conclusion: 1. mPSL inhibits L-VSCCsC of osteoblasts; and 2. The serum containing Chengzai Pill increases L-VSCCsC of osteoblasts pretreated with mPSL.     

不同时辰电针对大鼠脑内亮氨酸脑啡肽含量的影响

<正> 祖国医学对疾病的治疗历来主张“因时制宜”,强调时间因素在治疗疾病中的重要意义,“子午流注”和“灵龟八法”等时间针法更集中体现了针刺治疗与时间的密切关系。近年来,随着现代时间生物学和时间医学的兴起和迅速发展,时间因素对针刺疗效     

针灸治疗高血压病的临床和实验现状

高血压是指动脉血压高于正常的慢性疾患,属于中医弦晕,头痛等范畴。现将近年来针灸治疗高血压病的临床和实验研究简述如下: 一、针刺治疗高血压病的方法和效果 1、手针疗法:赵氏[1]采用针刺风池、太冲治疗原发性高血压,伴有头痛剧、目赤胀者加刺太阳。均捻转进针,中强刺激,留针20分钟,每日治疗1次,7天为1疗程。治疗100例,显效60例,有效19例,好转12例,无效9例,总有效率为91％。朱氏等轮流针刺曲池、足三里和合谷、太冲两组穴位,每日针刺一组穴,连续治疗10天。     

Study on the Mechanism of Compound Mistletoe Fluidextract in Relieving Hypertension

To observe the effect of Fufang Jisheng Liujin Gao （复方寄生流浸膏 Compound Mistletoe Fluidextract） on blood pressure in the spontaneous hypertensive rats （SHR） and the renal hypertensive dogs （RHD）. Methods： The blood pressure-decreasing effects of single administration and 14-day consecutive administration of Compound Mistletoe Fluidextract （CMF） in SHR and RHD were investigated and compared with that of Niuhuang Jiangya Wan （牛黄降压丸 Bezoar Hypertension-relieving Pills）. Results： Both single administration and 14-day consecutive administration of CMF had significant hypotensive effects in SHR and RHD. Conclusion： The hypotensive action of CMF is gradual, but lasts for a longer period, with a dose-effect relationship in a range of doses.     

Effect of Runing II on the Growth and Metastasis of Transplanted Tumor in Mammary Cancer-bearing Mice and Its Mechanism

Objective： To study the effect of Runing II （a Chinese herbal preparation for mammary cancer） on the growth and metastasis of transplanted tumor of mammary cancer MA-891-bearing TA2 mice and its mechanism. Methods： The model of mammary cancer MA-891 cell strain transplanted tumor of TA2 mice with lung metastasis were developed to observe the effect of Runing II on the growth and metastasis of the transplanted tumor. The immunohistochemical method and image analysis were adopted to detect the levels of vascular endothelial growth factor （VEGF）, vascular endothelial growth factor receptor （VEGFR）, and micro-vessel count （MVC） and micro-vessel area （MVA）. Results： In the Runing II group, the tumor weight inhibition rate and the lung metastasis inhibition rate were 37.3% and 65.4% respectively, the tumor growth and lung metastasis were obviously inhibited; And the levels of VEGF and VEGFR, MVC and MVA were significantly decreased as compared with those in the tumor-bearing control group （P〈0.05）. Conclusion： The Chinese herbal preparation Running II can inhibit the metastasis of tumor through inhibiting the angiogenesis, and the mechanism is possibly related with down-regulation of VEGF and VEGFR expression.     

针刺镇痛中α和β受体的作用及其对脑内5—羟色胺代谢的调节(摘要)

为探讨针刺镇痛中α和β受体的作用及对脑内5羟色胺(5-HT)代谢的调节,本文分别观察了大鼠腹腔注射α受体阻断剂酚妥拉明和β受体阻断剂心得安对电针镇痛效应和5-HT及其主要代谢产物5-羟吲哚乙酸(5-HIAA)含量变化的影响。实验用健康大鼠,体重250克左右。每次实验选取6只体重相似的动物,随机分为6个组:(1)对照组:注射生理盐水;(2)电针组:注射生理盐水20分钟后电针;(3)酚妥拉明组:注射酚妥拉

不同频率电针对急性实验性关节炎大鼠痛阈及血浆环核苷酸和皮质醇含量的影响

观察两种频率（５Ｈｚ和１００Ｈｚ）电针对急性佐剂性关节炎大鼠压力缩肢阈及血浆ｃＡＭＰ、ｃＧＭＰ和皮质醇含量的影响。结果表明,这两种频率电针均能明显升高关节炎大鼠痛阈,但两者的作用无明显差异;这两种频率电针均能提高血浆ｃＡＭＰ和ｃＧＭＰ含量,两者对血浆ｃＧＭＰ含量的升高作用有非常显著的差异;５Ｈｚ电针镇痛效应与血浆ｃＡＭＰ含量有显著相关;５Ｈｚ电针能明显升高血浆皮质醇含量。提示不同频率电针可产生不同效应,它们产生镇痛作用的机制可能有所不同
