根据22头日本三陆沿岸白胸拟鼠海豚的检测结果,研究了必需元素铁在13种组织和器官中的蓄积特征。肺、肝脏和脾脏中铁的浓度显著高于其它脏器,铁在皮肤和鲸脂中的浓度却非常低。研究发现,鲸类肝脏中铁的平均浓度与其最大潜水持续时间有着极其显著的正相关(y=285.17x0.5267;r2=0.92;y:a肝脏中铁的平均浓度,单位为μg·g-1干重;x:最大潜水持续时间,单位为min)。利用该关系式,首次推测白胸拟鼠海豚的最大潜水持续时间为11.85min。

选取80年代产自冰岛北大西洋和北大西洋东部海域的鱼肝油,对其中含有的耐分解有机氯化合物浓度进行了测定,以了解有机氯分布的空间变化,跟踪其可能来源和传送到挪威北极的途径。测定的化合物有多氯联苯、滴滴涕、六六六、六氯苯、氯丹、环氧七氯以及狄氏剂等。产自上述海域的鱼肝油含有机氯浓度很高,尤以波罗的海产品含量最高。各类有机氯含量以多氯联苯和滴滴涕居首位,六氯苯、氯丹、六六六以及狄氏剂的浓度相对较低,并因地而异。空间变化最大的是滴滴涕类,其次是多氯联苯类、六氯苯、狄氏剂和氯丹类。除六六六类以外的所有有机氯,其在不同海域间的变化从统计上看是显著的(5%水平)。尽管由南向北、由近海到远洋有机氯浓度趋于降低,但其滴滴涕、氯丹和六六六的体/代谢物比率在不同取样海区有各自的组成特征。较易传送的滴滴涕、六六六和氯丹体/代谢物,在产自北大西洋遥远海域的鱼肝油中占较大比重,这说明挪威北极和北大西洋温水海域都受到可能来自大西洋东部和南部相同有机氯污染源或污染途径的影响。

S(+)-Flurbiprofen Shows Potent PGE2 Inhibitory Activity in Inflammatory Cells, Superior Cell Transport Activity and Skin Permeability

引用

Pharmacology & Pharmacy 2016年第8期7卷 305-312页

作者： Yoshihisa Toda Masanori Sugimoto Hiromi Endo Miho Kamezawa Ichimaro Yamada Shogo Kawabata shinsuke Kaku Noboru Otsuka Hideo Matsumoto Research Headquarters Taisho Pharmaceutical Co. Ltd. Saitama Japan Mitsubishi tanabe Pharma Corporation Tokyo Japan Research Department Tokuhon Corporation Saitama Japan Development Headquarters Taisho Pharmaceutical Co. Ltd.

We developed a novel topical non-steroidal anti-inflammatory drug (NSAID)patch, S(+)-flurbiprofen plaster, (SFPP), containing S(+)-flurbiprofen (SFP), an enantiomer of flurbiprofen (FP). In a previous study conducted in an animal model, we showed good skin absorption and potent analgesic efficacy of SFPP. In this study, to examine the superior features, as an NSAID patch, of SFP as compared to FP and R(-)-flurbiprofen (RFP), we tested the stereospecificity of SFP actions on Prostaglandin E2 (PGE2) inhibition in rat inflammatory leukocytes and in the binding activity of the drug to cells, and also the in vitro skin permeability of the drug in the Yucatan micropig (YMP). SFP showed potent inhibitory activity on PGE2 production from peritoneal leukocytes stimulated with a bacterial suspension, as compared to RFP and FP. The half maximal (50%) inhibitory concentration (IC50) values were 14 nM for SFP, 52 nM for FP, and 17,000 nM for RFP. In the cell binding study, significant and rapid increase of SFP binding to polymorphonuclear leucocytes (PMNs) was observed at 5 min after incubation, eventually reaching a steady state. SFP showed significantly higher binding activity for the inflammatory leucocytes as compared to RFP, suggesting its superior transfer potency. The skin permeability profile of SFP, RFP and FP in the YMP model showed that the rank order of the cumulative amount of permeated compounds in the skin was SFP > RFP > FP. The steady-state permeation rate (Flux) of SFP was significantly higher than that of FP (4.89 and 1.55 mg/cm2/h, respectively, p = 0.0068), indicating the remarkably superior skin permeability of SFP. SFP exerted potent inhibitory activity on PGE2 production and superior binding activity to the PMNs and skin permeability, as compared to FP and RFP. These results suggest that SFP possesses favorable characteristics for use as an active ingredient in the NSAID patch.
