ABSTRACT
Abstract Hypertension is considered as a chronic and complex disease relating to multiple systemic systems. Apart from lowering blood pressure, the final purpose of the treatment lies in reducing the variability of blood pressure and other risk factors. Traditional Chinese medicine (TCM) has a long history of treating hypertension. This study was designed to determine the effect of Liu-Wei-Di-Huang-Fang (L-W-D-H-F), a compound used in traditional Chinese herbal medicine, to treat salt-sensitive hypertension (SSHT) induced by a high-salt and high-fat diet. L-W-D-H-F was prepared from six plant extracts. It was dissolved in 0.9% sodium chloride solution prior to use. Male Sprague-Dawley (6 weeks) rats were randomly divided into four groups normal diet (CON); HSF (Without Drug Intervention); VAL (Valsartan 13.33 mg/kg/day); and LW (L-W-D-H-F 8.13 g/kg/day). Six weeks after blood pressure treatment, plasma biochemical analyses and histological and functional examination of the kidney were performed. L-W-D-H-F decreased the levels of mean arterial pressure (MAP), fasting blood glucose (FG), insulin (INS), high-density lipoprotein cholesterol (HDL-c), homeostasis model assessment of basal insulin resistance (HOMA-IR) and angiotensin II (Ang II) from plasma and Ang II and renin from kidney. It also promoted the excretion of urinary Na(+), reducing the loss of urinary K(+) and microalbuminuria (MAU), and improved the glomerular afferent arteriole, arterioles and each kidney unit. Together, these results suggest that L-W-D-H-F is capable of moderately reducing MAP in salt-sensitive hypertension and can work at different levels on multiple differential targets.
