[摘要]研究阿萨伊对虚热证、虚寒证大鼠生物学表达特征的影响。SD大鼠分为空白组;虚热模型组,虚热模型加黄柏组、加阿萨伊高、低剂量组;虚寒模型组,虚寒模型加肉桂组、加阿萨伊高、低剂量组;采用每日肌肉注射地塞米松磷酸钠、氢化可的松琥珀酸钠1次、连续21 d的方法制备大鼠虚热模型、虚寒模型;通过放免法检测环核苷酸(cAMP,cGMP),内分泌激素(T3,T4,rT3)指标变化;通过比色法检测代谢(TP,UA,TC,TG,ALB)指标变化。虚热阿萨伊高剂量组能降低血清中cAMP,cAMP/cGMP值(分别P<0.05,P<0.001);虚热阿萨伊高剂量组均能显著降低T3,T4,rT3值(分别P<0.01,P<0.001,P<0.05);虚热阿萨伊高剂量组均能显著降低TP,UA,TC,TG,ALB值(分别P<0.001,P<0.05,P<0.05,P<0.05,P<0.01);阿萨伊对虚寒模型作用不明显。阿萨伊同黄柏一致,表现出对虚热模型大鼠的调整作用;与肉桂相反,对虚寒模型大鼠的指标纠正不明显。该文从同类比较、异类反证角度验证了理论推导的阿萨伊中药寒凉药性。

[Abstract]To study the effects of Acaí on biological expression characteristics in rats with deficiency-heat and deficiency-cold syndromes, SD rats were divided into blank group, deficiency-heat model group, deficiency-heat+Phellodendri Chinensis Cortex group, deficiency-heat+Acaí high dose and low dose groups, deficiency-cold model group, deficiency-cold+Cinnamomi Cortex group, deficiency-cold+Acaí high dose and low dose groups. The rats were treated with intramuscular injection of hydrocortisone (20 mg·kg-1) or dexamethasone sodium phosphate (0.35 mg·kg-1) for 21 days to set up deficiency-heat model and deficiency-cold models. The levels of cAMP, cGMP, T3, T4 and rT3 were detected by radioimmunoassay. The levels of TP, UA, TC, TG and ALB were detected by colorimetry. The level of cAMP, cAMP/cGMP in serum were reduced in Acaí high dose group (P<0.05, P<0.001). The levels of T3, T4 and rT3 were significantly reduced in the Acaí high dose group (P<0.01, P<0.001, P<0.05). The levels of TP, UA, TC, TG and ALB were significantly reduced in the Acaí high dose group (P<0.001, P<0.05, P<0.05, P<0.05, P<0.01). However, Acaí had no obvious effects on deficiency-cold models. Acaí showed the same effect with Phellodendri Chinensis Cortex in adjusting the levels of deficiency-heat rats; but unlike Cinnamomi Cortex, Acaí showed no obvious effects in adjusting the levels of deficiency-cold rats.

阿萨伊(英文名Aaí)又名巴西莓,来源于棕榈科植物阿萨伊棕榈树Euterpe oleraceae Mart.的新鲜果实[1],作为南美洲地区一种常用草药,在巴西、秘鲁、哥伦比亚、苏里南等地使用广泛[2],2013年由卫生部引入我国[3]。自古以来中医药就有吸收外来医药文化引进新资源品种的传统,如《本草纲目》收录外来药物96种[4],《经史证类备急本草》收载的外来药物达200多种[5],丰富了本草学品种。然而阿萨伊能否引入中药从而与我国已有的中药进行配伍使用发挥医疗保健作用,尚需要进行理论及实验多方面的研究。

寒热药性作为中药性能的主要元素之一,是中药性味归经研究的核心和主体内容,更重要的是它已成为当前药性研究的主要着眼点和切入点[6]。根据巴西、秘鲁等南美地区传统医学记载,阿萨伊可用于治疗痢疾,皮肤溃疡,发烧以及糖尿病,脱发,出血,肝炎、黄疸等肝脏疾病,肾脏疾病,疟疾,月经不调,经期疼痛和肌肉酸痛等。……
