The mechanism of Tongmai Oral Liquid (TOL) for chronic nephritis rat model with Qi-deficiency and blood-stasis syndrome was studied.The model was established by adding Qi-deficiency and blood-stasis syndrome to the chronic nephritis rats. The experimental rats were randomly allocated to 5 groups: Group A (treated with high dosage of TOL), Group B (treated with low dosage of TOL), Group C (treated with Jinshuibao), Group D (model control group) and Group E (normal control group). After 4 weeks of treatment, general health state, biochemical indexes including T lymphocyte subgroup and blood rheology, and pathological damage of kidney tissue were much improved in Group A than Group B and Group C. It is indicated that TOL can improve the renal function and delay the occurrence of glomerular arteriosclerosis in rats by reinforcing Qi, activating blood flow, regulating immune function, lessening the hypercoagulative state and reducing renal damage.

Objective To explore the effects of blood-circulation promoting and phlegm removing treatment on the structure, activity of Ca 2+ -Mg 2+ ATPase and malondialdehyde(MDA) content of mitochondria membrane in spontaneous hypertensive rats (SHR). Methods Spontaneous hypertensive rats (SHR) were classified into 14-week-old model group(Group C),28-week-old model group(Group D) and treatment group (treated with blood-circulation promoting and phlegm removing Chinese herbal medicine,Group E).Normal Wistar rats 14 weeks old (Group A)and 28 weeks old(Group B) served as the controls.The structure of myocardial mitochondria membrane were analyzed quantitatively by transmission electron microscope,and the activity of Ca 2+ -Mg 2+ ATPase and MDA content were also detected. Results Specific surface area of mitochondria was smaller, the activity of Ca 2+ -Mg 2+ ATPase was lower and MDA content was higher in SHR than the controls.MDA content increased as the duration of disease prolonged. Chinese herbal medicine could counteract the above changes. Conclusion Blood-circulation promoting and phlegm removing herbs can partially counteract the progress of left ventricular hypertrophy in SHR.
