Abstract:
ObjectiveTo investigate the Jiuqiang Naoliqing's (JNQ) histological influence on hearts, brains and kidneys of spontaneous hypertension rats (SHR). MethodsThe rats were randomly divided into four groups: Wistar control group, SHR group, higher dose JNQ treated SHR group(0.530 g/kg) and lower dose JNQ treated SHR group(0.265 g/kg). The treatment lasted five weeks, and the rats' blood pressure were monitored through tail pulse. After the perfusion procedure, rats' hearts, brains and kidneys were rapidly removed in low temperature condition and stored in 10% formalin solution of 4 ℃.Then routine sections were obtained and the slides were stained with HE.ResultsBefore treatment, the blood pressure of SHR groups were distinctly higher than that of the control group(P<0.01), nevertheless, no obvious blood pressure downgrade were observed after three week and five week treatment. Histopathologic study showed: in SHR group,heart with hypertrophic cardiac muscle, proliferative arterial wall and strictured lumina; Cortex with angiostenosis, proliferative vascular wall and large perivascular space; Glomerulus atrophy with hyaline degeneration. These pathologic changes got respective alleviation after five week treatment of JNQ, particularly in higher dose group.ConclusionSHR who got five week treatment of JNQ didn't gain obvious blood pressure downgrade. But the treatment did good to their vital organs and can obviously alleviate hearts, brains and kidneys' pathologic changes.
