3种不同血瘀证动物模型的建立与评价
The establishment and evaluation of three different kinds of animal model of blood stasis syndrome
摘要
Abstract
Aim To establish phlegm and blood stasis, qi-stag-nation and blood stasis, phlegm turbid+qi-stagnation and blood stasis model in rats and to study the characteristics of animal models with different blood stasis. Methods SD rats were ran-domly divided into normal group, high fat diet group, chronic unpredictable mild stress group ( CUMS ) and high fat diet +chronic unpredictable mild stress group. Different states of blood stasis rat models were established by corresponding factors for 6 weeks. Indexes of weight, open field behavior, serum lipids and corticosterone were monitored dynamically at the 2 nd, 4 th, 6 th weeks. At the end of the experiment(6th week), the heart func-tion was detected by small animal ultrasound and the left ventric-ular intubation. The blood rheology indexes were detected by the viscosity tester and red blood cell deformation/aggregation test instrument. Results Compared with the normal group, blood stasis could be induced by high fat diet and chronic unpredicta-ble mild stress, introducing the influence of different degree on animal behavior, blood lipids, heart function and blood viscosi-ty. When the two factors were superimposed, the changes of the indexes about blood stasis were the most significant. Perform-ance as: compared with normal control group, a significant re-duction was observed in body weight ( P < 0. 01 ); horizontal movement, vertical movement and movement time were reduced (P<0. 01 or P<0. 05) at the 2 nd week;at the 2 nd and 4 th week, serum corticosterone was increased ( P <0. 01 or P <0. 05) as well as TG at the 4 th and 6 th week (P<0. 01); at the 6 th week, velocity of blood was slowed down ( P<0. 01 );left ventricular anterior wall and posterior wall thickness at end-systolic was increased ( P<0. 01 or P<0. 05 ); left ventricular diastolic index was increased ( P<0. 01 ); the maximum rate of myocardial contraction was decreased ( P < 0. 05 ); the whole blood viscosity was increased ( P<0. 01 ) . Conclusions Blood stasis could be formed by high fat diet and chronic unpredictable mild stress, which has different characteristics. When the two factors are superimposed, the abnormal behavior, blood viscosi-ty, heart function, blood lipid and other indexes of the animal could obviously appear, which can provide the basis for the stud-y of blood stasis syndrome and related drugs.关键词
