海马不同提取物对雌二醇致肾阳虚小鼠的影响

Effects of different extracts from Hippocampus japonicus on kidney-yang deficiency mice induced by extradiol

目的观察海马4个提取物(水、正丁醇、醋酸乙酯、石油醚提取物)对雌二醇致肾阳虚模型小鼠的影响,认识其"甘,温,入肝、肾经"药性的现代科学内涵。方法采用ip苯甲酸雌二醇造成小鼠肾阳虚模型,对小鼠体征、肛温、抓力、游泳时间、自主活动、血清肌酐(Cr)及尿素(UR)、血液学指标、睾丸和精囊腺指数进行测定。结果海马4个提取物均能改善肾阳虚小鼠体征,升高精囊腺指数和血液RBC、Hb、PLT,降低血清UR水平;海马水提取物、石油醚提取物均能提高肾阳虚小鼠肛温、抓力、游泳时间、自主活动次数、睾丸指数、WBC、淋巴细胞(LY)、单核细胞(MO)、嗜中性粒细胞(NE);正丁醇提取物能提高小鼠自主活动次数、NE;醋酸乙酯提取物能提高小鼠抓力、游泳时间。结论海马的药效可作为改善肾阳虚证之腰膝酸软、性欲减退、畏寒肢冷、精神萎靡、阳虚水泛,以及肾精亏虚、肝气虚弱所致血液亏虚的基础,并作为其甘温、入肝、肾经药性现代科学内涵的组成部分。海马水提取物和石油醚提取物的作用较为接近且较强,为认识海马甘、温、归肝肾经共同药效物质群提供了启示。

Objective To observe effects of four extracts （water, n-butanol, acetoacetate and petro- leum benzine extracts） from Hippocampus japonicus on kidney-yang deficiency mice induced by extradiol, and reveal the modern scientific connotation about sweet-flavor, warm-nature, meridian tropism in liver and kidney. Methods Kidney-yang deficiency mice was induced by intraperitoneal injection of estradiol benzoate. Effects of four extracts from H. japonicus were observed by measuring physical signs, rectal temperature, grip strength, swimming time, autonomic mobility, creatinine （Cr） and urea （UR） level in serum, haematological indexes, testis index and seminal vesicle index. Results All the four extracts from H. japonicus could markedly improve physical signs and increase seminal vesicle index, RBC, Hb and PLT in blood, and decrease UR level in serum of kidney-yang deficiency mice, water extract and petoleum benzine extract could increase rectal temperature, grip strength, swimming time, autonomic mobility, tes- tis index, WBC, lymphocyte （LY）, monocyte （MO）, and neutrophilic granulocyte （NE）, n-butanol ex- tract could increase autonomic mobility and NE, acetoacetate extract could enhance grip strength and pro- long swimming time. Conclusion All above effects of extracts from H. japonicus could be as the basic of improving kidney-yang deficiency, could be an important part of the modern scientific connotation about sweet-flavor, warm-nature, meridian tropism in liver and kidney. Effects of water extract and petroleum ether extract were closer and stronger, which offer enlightenment for searching the common effective substance groups of H. japoniacs.
