Effects of different directions of moxibustion therapy on hemorheology in rats with blood stasis due to cold retention
Tóm tắt
To investigate the effects of different directions of moxibustion therapy on hemorheology in rat models with blood stasis due to cold retention. A total of 32 Wistar rats were randomly divided into 4 groups, based on the random digits table, including a normal group, a model group, a moxibustion along the meridian group, and a moxibustion against the meridian group, with 8 rats in each group. Except the normal group, the other 3 groups were used to make the rat models with blood stasis due to cold retention. Rats in the moxibustion along and against the meridian groups accepted moxibustion therapy in different directions on the trunk segment of the Bladder Meridian after successful modeling. Moxibustion for 10 min every day, and 7 d as a course of treatment. Two courses of treatment (a total of 14 d) were carried out. Quantitative score of signs and symptoms change was observed once a week, with a total of 7 times. Hemorheological indexes of rats were detected when the treatment finished. The quantitative scores of signs and symptoms in the model, moxibustion along the meridian and against the meridian groups were significantly higher than those in the normal group after modeling (P<0.05). When the treatment finished, the quantitative score of signs and symptoms in the model group was significantly higher than that in the normal group (P<0.05); the quantitative scores of signs and symptoms of rats in the moxibustion along and against the meridian groups were significantly lower than that in the model group (P<0.05); the quantitative score of signs and symptoms in the moxibustion along the meridian group was significantly lower than that in the moxibustion against the meridian group (P<0.05); the whole blood viscosity and erythrocyte aggregation index in the model group were significantly higher than those in the normal group (P<0.05), however the increases of erythrocyte hematocrit and erythrocyte sedimentation rate were not obvious (P>0.05); whole blood viscosity and erythrocyte aggregation index in the moxibustion along and against the meridian groups were significantly lower than those in the model group (P<0.05), while there were no statistically significant differences between the moxibustion along the meridian group and moxibustion against the meridian group (P>0.05). Moxibustion along and against the meridian both showed different degrees of improvement for hemorrheology and symptoms of blood stasis due to cold retention. Improvement for symptoms of blood stasis due to cold retention was better in the moxibustion along the meridian group than that in the moxibustion against the meridian group. The influence on rat hemorrheology showed no significant difference between moxibustion along the meridian and moxibustion against the meridian.
