The Rise of a New Psychoactive Agent: Salvia divinorum

Since the 1990s, there has been a rise in the availability and recreational use of a herbal plant called Salvia divinorum. Numerous internet websites have advertised it for sale as a legal herbal alternative to illegal hallucinogens. Initial data surveying use has indicated many young adults are obtaining and using this herb for its psychoactive properties. Reported methods of ingestion for the plant include chewing, and smoking leaves or fortified extracts. Subjective effects of the plant include, affect changes, psychedelic-like changes in perception, and even loss of consciousness. Although the pharmacological properties and possible antidepressant effects have been studied in recent years, little information is known about potential negative impact resulting from recreational use, and scant information about Salvia divinorum currently exists in the psychological and substance abuse literature. While Salvia divinorum appears to be a substance with some therapeutic potential, it also poses some significant dangers as a substance of varying legal status with a potential for abuse.     

丹参改善骨骼肌缺血再灌注损伤的超微结构观察

目的:通过透射电镜观察骨骼肌缺血再灌注损伤过程的病理生理变化探讨丹参的干预作用及机制。方法:采用90只清洁级雄性SD大鼠,6只作为健康对照组,84只行左侧提睾肌主滋养动脉夹闭造模,在缺血2.5 h时,丹参组腹腔注射丹参(42只),对照组注射等剂量的生理盐水(42只),两组分别设缺血再灌注10、20、30、40、50、60、90 min观测点(每个观测点6只)。观测结束后,迅速切取提睾肌,放入电镜固定液。电镜下进行组织形态学观察。结果:健康对照组正常情况下,组成肌原纤维的粗、细2种肌丝沿其长轴排列,每条肌原纤维上均可见明暗相间的带,肌浆内见有较多糖原颗粒及少量内质网、线粒体等细胞器,肌浆网纵向分布于肌原纤维周围,线粒体膜及嵴清晰可见,基质着色深,无肿胀、空泡形成等改变,在肌丝之间分布有较多糖原颗粒;骨骼肌缺血再灌注后10、20、30、40、50、60、90 min的2组各观测点,其病理变化较相似,肌丝模糊、凌乱,部分溶解、消失,甚至完全消失,肌浆网不同程度扩张,线粒体变大变圆,基质变淡,嵴变短变少甚至消失,部分线粒体极度肿胀,呈空泡状。丹参组,其病理变化大体相似,肌纤维均有不同程度恢复。结论:骨骼肌缺血再灌注损伤导致线粒体极度肿胀,肌纤维紊乱。丹参能有效地消除线粒体的水肿,恢复肌纤维,减轻骨骼肌缺血再灌注损伤。

A Comparative Study of Dihydroartemisin in Compounds in Treatment of Uncomplicated Falciparum Malaria in Kampong of Cambodia

Objective: To compare the safety and efficacy of two compounds of dihydroartemisinin(DHA) -Artekin and Artekin (T) in the treatment of uncomplicated falciparum malaria. Methods:The regimen of 8-tablet for 2 days of Artekin and Artekin (T) were applied to 100 patients with uncomplicated falciparum malaria, who were randomly divided into two groups. Each group contained 50 cases. The cure rate, the mean parasites clearance time, the mean fever clearance and side-effects were observed to assess the safety and efficacy of the compounds used. Results: The mean parasites clearance time was 31. 7±9.0 hours in the Artekin group and 32. 8±8. 8 hours in Artekin (T) group respectively; the mean fever clearance time was 12. 7±7. 2 hours in Artekin group and 16. 5±7. 9 hours in Artekin (T) group; there were no recrudescence case in both groups within the 28 days of follow-up, the cure rates in Artekin group and Artekin (T) groups were 100%. It indicated that the tolerability of both compounds were very good, the     

丹参对大鼠肝细胞凋亡及相关基因表达的影响

目的 :探讨丹参对大鼠肝脏缺血再灌注时肝细胞凋亡及相关基因 (Bcl-2和 Bax)表达的作用。方法 :SD大鼠随机分为假手术 (SO)组、缺血再灌注 (IP)组及丹参 (SM)治疗组 ,并根据再灌注不同时间点再分为 7个亚组。后 2组缺血时间均为 30 min。分别于再灌注 0、1、6、12、2 4、48、72 h后采取肝脏组织标本。分别采用原位末端标记 (TU NEL)技术和免疫组化 ,检测大鼠肝组织细胞凋亡及 Bcl-2、Bax蛋白表达水平。结果 :缺血再灌注组细胞凋亡 1h开始出现 ,12～ 2 4h达峰值 ,Bcl-2、Bax的表达增强 ;2 4h后凋亡峰缓慢下降 ,Bcl-2、Bax的表达陆续减弱。丹参治疗组与缺血再灌注组相比于 1～ 72 h各时间点 Bcl-2表达增强 ,Bax表达减弱 ,凋亡细胞数明显减少 (P<0 .0 5 ,P<0 .0 1)。结论 :丹参可通过增强 Bcl-2表达 ,抑制 Bax表达 ,而抑制肝脏缺血再灌注时肝细胞凋亡。因而可以预防肝脏缺血再灌注损伤。
