BACKGROUND: How to choose traditional Chinese remedy to treat cerebrovascular disease, not only improving the brain blood supply but also not affecting the blood pressure and heart rate, has been a promising research.OBJECTIVE: To study the role of yangyintongnao granule on average blood pressure and heart rate in anaesthetized dog.DESIGN: Complete grouping design and randomized controlled study based on hybrid dog.SETTING: Department of Anesthesiology, Xijing Hospital, Fourth Military Medical University of Chinese PLA and Department of Pharmacology, Faculty of Preclinical Medicine, Fourth Military Medical University of Chinese PLA MATERIALS: The experiment had finished by Cardiovascular Laboratory of Physiology Department in the Fourth Military Medical University of Chinese PLA from March to June 2003. Totally 23 healthy hybrid dogs in either sex were selected. These dogs were divided randomly into 4 groups: high dose group of yangyintongnao( n = 8), moderate dose group of yangyintongnao ( n = 6), low dose group of yangyintongnao( n = 5) and saline group( n = 4).METHODS: Anesthetic dogs in high, moderate and low dose group of yangyintongnao granule were given different doses of yangyintongnao granule: 2 g/kg, 1 g/kg and 0. 5 g/kg respectively. All doses of drug were calculated based on the body mass of dogs, and the drugs were dissolved in 100 mL saline and given through the gastric canal. Dogs in saline group were perfused with equal saline. Aortic average blood pressure was measured by femoral artery intubation via a piezometric transducer. Heart rate was obtained from R-R intervals of a standard Ⅱ lead of electrocardiograph(ECG). The mean blood pressure and heart rate were recorded 0. 5, 1, 1.5, 2.0,3.0, 4. 0, 5.0, 6. 0 hours after treatment.MEAN OUTCOME MEASURES: The changes of blood pressure and heart rate at different time before and after medication.RESULTS: Totally 29 dogs were brought into the final analysis. Blood pressure: The mean blood pressure was reduced -5.4% to -6. 2% respectively in high dose group and moderate dose group after treatment. But in low dose group the average blood pressure sometimes increased sometimes decreased, mainly decreased. It increased by 6.6% ( P ＞ 0. 05) and decreased by -4. 1% ( P ＞ 0.05) at maximum. The average blood pressure in saline group changed by - 9.6% ( P ＞ 0.05). Heart rate: The heart rate in high and medium dose group gradually reduced as time went on. It reduced by - 4. 4%, - 12.2% and - 9.5% respectively in high, moderate and low doses group. The change in each group was not statistically significant as the same in saline group( P ＞ 0.05).CONCLUSION: Yangyintongnao granule has no significant influence on average blood pressure and heart rate.
