신장 양 결핍 마우스 모델에 대한 Lanshi 토닉의 조절 효능

요약

목적

신장 양 결핍 상태에 대한 란시(Lanshi)토닉의 조절 효과 및 관련 메커니즘 연구하고자 한다.

방법

ICR 마우스는 체중에 따라 무작위로 정상 군, 모델 군, 란시 토닉 고용량, 중용량 및 저용량 그룹 등 5 개 그룹으로 분류되었다. 마우스모델에게 연속적으로 7 일 동안 50 mg/kg hydrocortisone sodium succinate를 복강 내 주사하고, 신장-양 결핍 증후군의 마우스 모델을 유발시키기 위해 주사를 3 일 동안 중단시켰다. 동시에, 모든 용량의 란시 토닉을 각 신장-양 결핍 증후군의 마우스 모델에 각각의 란시 토닉을 투여하고 정상 그룹 및 모델 그룹에 동일한 조건 하에서 증류수를 제공 하였다. 마우스의 체질량, 모발 색 및 체형을 관찰하고 기록하였고, 비장 지수, 흉선 지수 및 부신 지수를 계산 하였다. ELISA로 소변 내17-OHCS 함량 측정 및 혈청 코티솔, ACTH, cAMP, cGMP의 함량을 측정하고 cAMP/cGMP의 비율을 계산하였다.

결과

정상 그룹과 비교하여, 혈청 cGMP가 유의하게 더 높은 경우를 제외하고(p<0.01), 모델 그룹 마우스의 상기 지수는 유의하게 더 낮았다(p<0.05, p<0.01). 모델 그룹과 비교하여, 고용량 및 중용량의 란시 경구용액은 소변 17-OHCS 함량에서 유의 한 변화가 없었지만(p>0.05), 상기 언급 된 다른 지표에 대해 상이한 개선 효과를 가졌다(p<0.05, p<0.01).

결론

Lanshi 토닉은 신장 양 결핍 상태에 대한 조절 효과를 가지며, 이는 부신 피질의 분비 기능 조절 및 사이 클릭 뉴클레오티드 수준의 불균형 조정과 관련 될 수 있다고 사료된다.

Abstract

Purpose

To study the regulatory effect of Lanshi tonic on kidney-yang deficiency model and its related mechanism.

Methods

ICR mice were randomly divided into five groups according to body weight: normal group, model group, Lanshi tonic high, medium and low dose group. Mice with kidney-yang deficiency syndrome were induced by hydrocortisone sodium succinate by intraperitoneal injection, 50 mg/kg for 7 days. At the same time, all groups were given corresponding medicine by oral administration for 10 days. The body mass, hair color and body shape of mice were observed and recorded. Spleen index, thymus index and adrenal index were calculated. Level of urine 17-OHCS was measured by ELISA. Level of serum Cortisol, ACTH, cAMP, cGMP and ratio of cAMP/cGMP were measured by ELISA.

Results

Compared with the normal group, the above indexes of the model group mice were significantly lower (p<0.05, p<0.01), except the serum cGMP was significantly higher (p<0.01). Compared with the model group, Lanshi tonic at high and medium doses had no significant change in urine 17-OHCS content (p>0.05), but had different improvement effects on the other indicators mentioned above (p<0.05, p<0.01).

Conclusion

Lanshi tonic can regulate the state of kidney-yang deficiency, which may be related to the regulation of adrenocortical secretion function and the imbalance of cyclic nucleotide levels.

中文摘要

目的

研究澜仕口服液对肾阳虚状态的调节作用及相关机制。

方法

将ICR小鼠按体质量随机分为5组:正常组、模型组、澜仕口服液高、中、低剂量组。小鼠腹腔注射氢化可的松琥珀酸钠,50 mg/kg,连续7天,停止注射3天造成肾阳虚证候小鼠模型。造模同时给予各剂量澜仕口服液,正常组和模型组在同等条件下给予蒸馏水。观察并记录小鼠体质量、毛色、体态等一般体征状态,解剖、称量并计算脾指数、胸腺指数和肾上腺指数,ELISA法检测尿液17-OHCS含量,ELISA法检测血清Cortisol、ACTH、cAMP、cGMP含量、计算cAMP/cGMP比值。

结果

与正常组比较,模型组小鼠除血清cGMP显著升高外,上述其他指标均显著降低(p<0.05, p<0.01)。与模型组比较,澜仕口服液高剂量和中剂量除对尿液17-OHCS含量无显著改变(p>0.05)外,对上述其他指标均有不同程度的改善作用(p<0.05, p<0.01)。

结论

澜仕口服液对肾阳虚状态具有调节作用,可能与调节肾上腺皮质分泌功能和调整环核苷酸水平失衡相关。

Introduction

肾阳虚是肾阳虚衰,温煦失职,气化失权所表现的一类虚寒证候。当处于肾阳虚状态时,全身机能降低,代谢下降,体温降低,免疫功能减退,腰膝酸软,易疲劳等(Zhang et al., 2008Xu et al., 2015)。现代医学研究表明,肾阳虚证与神经-内分泌-免疫系统的功能变化密切相关,下丘脑-垂体-靶腺轴(肾上腺轴和性腺轴)的功能障碍或低下是肾阳虚证的基础(Shen, 1997)。
澜仕口服液由黄芪、杜仲、生地黄、巴戟天、枸杞子和黄精组成,具有增强免疫力、缓解体力疲劳的功效。本研究采用经典的氢化可的松法制作肾阳虚小鼠模型(Chen, 1993; Lin et al., 2013; Jia et al., 2016),通过观察澜仕口服液对一般体征状态、免疫器官指数、肾上腺皮质功能及环核苷酸水平的影响,探讨澜仕口服液对肾阳虚状态的调节作用。

正常组小鼠毛发润泽、活动自如;连续注射氢化可的松琥珀酸钠7天,停止3天后,模型组小鼠出现精神倦怠、活动减少、反应迟钝、皮感温度低、喜扎堆、蜷曲拱背、体毛干枯稀疏无光泽,爪甲与耳朵颜色变淡、饮食饮水减少等表现。各组小鼠造模前体质量均一,造模后模型组体重较正常组显著下降(p<0.01)。澜仕口服液各剂量组小鼠毛色和光泽度、迟钝蜷缩表现有所改善,各剂量组小鼠体质量均较模型组增加(p<0.05,p<0.01)。见Table 1

2. Effect of Lanshi tonic on organ index in mice with kidney-yang deficiency

连续注射氢化可的松琥珀酸钠7天,停止3天后,模型组小鼠脾指数、胸腺指数、肾上腺指数均较正常组显著降低(p<0.01);灌胃给予澜仕口服液后,各剂量组脾指数均较模型组显著升高(p<0.05,p<0.01),其中澜仕口服液中剂量组脾指数抑制率最高,达到25.99%;澜仕口服液高剂量组和中剂量组胸腺指数及肾上腺指数均较模型组显著升高(p<0.05),其中高剂量组胸腺指数抑制率和肾上腺指数抑制率最高,分别达到34.53%、16.15%。见Table 2

3. Effect of Lanshi tonic on adrenal cortex function in mice with kidney-yang deficiency

连续注射氢化可的松琥珀酸钠7天,停止3天后,模型组小鼠血清cortisone、ACTH和尿17-OHCS含量均较正常组显著降低(p<0.05,p<0.01)。澜仕口服液各剂量组血清Cortisone均较模型组升高(p<0.05,p<0.01);澜仕口服液高剂量组和中剂量组血清ACTH均较模型组升高(p<0.05);澜仕口服液各剂量组尿17-OHCS含量较模型组均无显著变化(p>0.05)。见Table 3

4. Effect of Lanshi tonic on cyclic nucleotide level in mice with kidney-yang deficiency

连续注射氢化可的松琥珀酸钠7天,停止3天后,与正常组小鼠比较,模型组小鼠血清cAMP含量降低,cGMP升高,cAMP/cGMP比值降低(p<0.01)。灌胃给予澜仕口服液后,各剂量组小鼠血清cAMP含量均升高,cGMP含量均降低,cAMP/cGMP比值均升高(p<0.05,p<0.01)。见Table 4

Discussion

肾阳虚者,其温煦、生殖、气化功能下降,以腰膝酸痛,虚寒及生殖能力下降为辨证要点(Qin et al., 2017) 。临床患者多见腰背酸痛、腰膝酸软、畏寒肢冷、嗜睡、耳鸣、耳聋、面色萎黄、发脱枯悴、性机能异常等(Zhang et al., 1989)。氢化可的松可升高血中糖皮质激素水平,抑制促肾上腺皮质激素释放,而使类固醇激素分泌减少,出现一系列“耗竭”现象(Qin et al., 2017; Dai et al., 2017),特别是突然停用,肾上腺轴的抑制状态立即暴露,出现一系列阳虚表现(Du et al., 2010)。氢化可的松作为外源性糖皮质激素造成的肾阳虚小鼠模型,可导致神经-内分泌-免疫系统的功能变化,从而引起内分泌器官肾上腺和免疫器官萎缩等(Xu et al., 2015)。环核苷酸是调节细胞功能活动的重要物质,中医的阴阳学说与环核苷酸理论有相似之处,阳虚时主要是cGMP 含量上升,cAMP/cGMP 比值降低(Chen, 1993)。有研究以大鼠cAMP 含量下降,cGMP 含量显著升高及cAMP/cGMP比值显著降低作为肾阳虚模型造模成功的评判标准(Gou et al., 2009; Ren et al., 2010; Zhang et al., 2015) 。
本实验研究显示,肾阳虚模型小鼠出现一系列的“耗竭”,即体重下降、精神倦怠、活动减少、反应迟钝、皮感温度低、喜扎堆、蜷曲拱背、体毛干枯稀疏无光泽,爪甲与耳朵颜色变淡、饮食饮水减少等;小鼠免疫器官脾、胸腺和内分泌器官肾上腺均发生萎缩;连续注射氢化可的松,突然停用后,肾上腺皮质功能受到抑制,分泌激素减少,小鼠血清ACTH、Cortisone和尿17-OHCS含量均降低;小鼠血清cAMP含量降低,cGMP升高,cAMP/cGMP比值降低,符合肾阳虚动物模型鉴定标准。本实验所用受试物澜仕口服液以黄芪和杜仲为君药,可益气补虚、补肝温肾;以生地黄和巴戟天为臣药,主入肾经,生髓填精;以枸杞子和黄精为佐药,平补肝肾精气、平补脾肾不足;全方配伍能温补肾阳、强筋健骨。灌胃给予肾阳虚模型小鼠后,可增加模型小鼠体重,改善模型小鼠毛色、光泽度和迟钝蜷缩等表现;可升高肾阳虚模型小鼠脾指数、胸腺指数和肾上腺指数;可升高血清ACTH和cortisone含量;可增加血清cAMP含量,降低cGMP含量,升高cAMP/cGMP比值。

Conclusion

澜仕口服液在一定程度上具有改善肾阳虚小鼠虚损耗竭、抑制免疫器官和内分泌器官萎缩的作用,其作用机制可能通过改善肾阳虚模型小鼠肾上腺皮质分泌功能、调整环核苷酸水平失衡、恢复机体代谢平衡,从而发挥对肾阳虚状态的调节作用。
