热原检查中的降温分析

药检人员在进行药品的热原检查中,首先要进行对动物家兔注射药液实验,即将一定剂量的供试品静脉注入家兔体内,在规定时间内,观察家兔体温升高的情况,以判断供试品中所含热原的限度是否符合规定.药典只规定上升的温度.但是,作为检验员在实验中,往往会碰到实验动物不升温,反而降温的现象,而且不是只降0.1℃,甚至降0.4℃,下面笔者就降温的原因做如下分析.     

医用臭氧对兔膝关节骨性关节炎软骨细胞IL-1β表达的影响

目的：观察臭氧对兔膝关节骨性关节炎软骨细胞IL-1β表达的影响。方法：成年新西兰大白兔36只,随机分为正常组4只、对照组16只、实验组16只;采用Hulth法将3组实验动物制成膝关节骨性关节炎模型。待造模成功后,实验组每日向膝关节腔内注射臭氧,连续7d;对照组关节腔内注射氧气,连续注射7d;正常组不作处理。于造模后第7d处死3组实验动物,DAB法检测膝关节软骨细胞IL-1β的表达。结果：IL-1β阳性细胞率：实验组与对照组比较差异有统计学意义（P〈0.05）;对照组与正常组比较差异有统计学意义（P〈0.01）。结论：医用臭氧能明显降低早期OA软骨中的IL-1β的表达,这可能是臭氧治疗骨性关节炎的重要机制之一。

Maklamicin, an antibacterial polyketide from an endophytic Micromonospora sp

A new spirotetronate-class polyketide, maklamicin (1), was isolated from the culture extract of an endophytic actinomycete of the genus Micromonospora. The structure and relative configuration of 1 were elucidated by interpretation of NMR and other spectroscopic data, and the absolute configuration was determined using the modified Mosher method. Maklamicin (1) showed strong to modest antimicrobial activity against Gram-positive bacteria.

Effect of an avocado oil-rich diet over an angiotensin II-induced blood pressure response

We studied the effect of an avocado oil-rich diet on (1) the blood pressure response to angiotensin II (AngII) and (2) the fatty acid composition of cardiac and renal membranes on male Wistar rats. The avocado oil-rich diet induced a slightly higher AngII-induced blood pressure response in the rats as compared to the control rats. In cardiac microsomes, avocado oil induced an increase in oleic acid content (13.18+/-0.33% versus 15.46+/-0.59%), while in renal microsomes, the oil decreased alpha-linolenic acid content (0.34+/-0.02% versus 0.16+/-0.12%), but increased the arachidonic acid proportion (24.02+/-0.54% versus 26.25+/-0.54%), compared to control. In conclusion, avocado oil-rich diet modifies the fatty acid content in cardiac and renal membranes in a tissue-specific manner. The rise in renal arachidonic acid suggests that diet content can be a key factor in vascular responses.     

Apigenin as an anticancer agent

Apigenin is an edible plant‐derived flavonoid that has been reported as an anticancer agent in several experimental and biological studies. It exhibits cell growth arrest and apoptosis in different types of tumors such as breast, lung, liver, skin, blood, colon, prostate, pancreatic, cervical, oral, and stomach, by modulating several signaling pathways. Apigenin induces apoptosis by the activation of extrinsic caspase‐dependent pathway by upregulating the mRNA expressions of caspase‐3, caspase‐8, and TNF‐α. It induces intrinsic apoptosis pathway as evidenced by the induction of cytochrome c, Bax, and caspase‐3, while caspase‐8, TNF‐α, and B‐cell lymphoma 2 levels remained unchanged in human prostate cancer PC‐3 cells. Apigenin treatment leads to significant downregulation of matrix metallopeptidases‐2, ?9, Snail, and Slug, suppressing invasion. The expressions of NF‐κB p105/p50, PI3K, Akt, and the phosphorylation of p‐Akt decreases after treatment with apigenin. However, apigenin‐mediated treatment significantly reduces pluripotency marker Oct3/4 protein expression which might be associated with the downregulation of PI3K/Akt/NF‐κB signaling.     

Polygodial, an antifungal potentiator

A series of sesquiterpene dialdehydes was isolated from the East African medicinal plants Warburgia stuhlmannii and Warburgia ugandensis (Canellaceae) as antibiotics, particularly against Saccharomyces cerevisiae, Candida utilis, and Sclerotinia libertiana. Among these sesquiterpene dialdehydes, polygodial [1] exhibited the most potent activity. When tested on S. cerevisiae, polygodial proved to be fungicidal rather than fungistatic. When the cells of S. cerevisiae are treated in vitro with polygodial for 10 min, the cell membrane becomes severely damaged, and many vesicles, possibly formed from the fragmented cell membrane, can be observed within the cytoplasm. The observation of cell membrane lesions led us to propose a rather innovative hypothesis: the use of polygodial to facilitate the transmembrane transport of exogenous chemicals into cells. For example, polygodial could be combined with an antibiotic having poor cell membrane permeability in an effort to increase its antibiotic activity by increasing its ability to gain entrance into the cell. We report here that a remarkably enhanced efficacy was obtained when actinomycin D was used in combination with polygodial. We believe polygodial may be acting as an "advance scout," punching holes in the plasma membrane and gaining an entrance into the cell for an antibiotic previously less effective because of problems with cell membrane permeability.     

Acupuncture research:an update

ABSTRACT The 1997 National Institutes of Health(NIH) Consensus Development Conference on Acupuncture was a landmark in the history of acupuncture research in the USA and the West.The Consensus Statement concluded,"There is sufficient evidence of acupuncture’s value to expand its use into conventional medicine and to encourage further studies of its physiological and clinical value." It also suggested that more high quality clinical research should be conducted.Since then,more than 600 randomized clinical trials have been conducted and published.Trial quality has significantly improved,and the field of acupuncture research is now much more     

Kava: an overview.

Since the first significant contact with Europeans in the 18th century, the Oceanic plant, Piper methysticum Forst. (Piperaceae) and the beverage prepared from it, both of which are called kava, have become familiar to much of the outside world through both the written and visual media. The ceremonial preparation and consumption of the beverage are probably its most conspicuous and spectacular features. Kava continues to occupy a central place in everyday life in the islands concerned, although its role has been somewhat diminished by time and outside influences. Despite the large body of literature on kava--about 800 entries are listed in a recent bibliography by Singh (1986)--there has been no comprehensive review on the subject. Earlier contributions by Keller and Klohs (1963) and Shulgin (1973) were selective in treatment and dealt primarily with chemical and pharmacological aspects. The monograph by Steinmetz (1960) remains a standard reference but understandably some of the information in it has become dated. The attention of the reader is also drawn to two excellent additions to the recent kava literature, by Lebot and Cabalion (1988) and Brunton (1989), which are, although somewhat restricted in focus, are very significant contributions to the subject. The present review paper provides an updated and a multidisciplinary overview of the subject. It was prepared on the basis of the author's personal experience--he is a native of Fiji and lived in that country for about 30 years--as well as the relevant literature listed in the Singh (1986) bibliography and some more recent publications.
