Abstract:
Background: Hypertensive nephropathy (HN) is one kind of kidney disorders caused
by long-term uncontrolled hypertension, usually resulting in severe kidney damage, including
inflammation and oxidative stress, no matter in cells or tissues, from patients with nephropathy. In
recent years, nephropathy accompanied by hypertension is becoming one of the main causes for
kidney replacement therapy, but few effective treatments have been reported for HN treatment.
Asystasia chelonoides (AC) is a kind of plant with the effects of anti-inflammation, lowering blood
pressure, and anti-oxidative stress. Still, the therapeutic effect of AC in HN rats is not clear.
Methods: To establish HN model by feeding high sugar and high fat diet spontaneously hypertensive
rats. Blood measurement, HE staining, PAS staining and biochemical analysis and were used
to assess the therapeutic effects of AC extracts and western blotting analyzed the underlying
mechanisms of AC extracts treatment in the HN rat model.
Results: AC extracts could significantly lower systolic blood pressure (SBP), diastolic blood pressure
(DBP) and mean blood pressure (MBP) in HN rats; and reduce the expression of total protein
(TP), blood urea nitrogen (BUN), microalbuminuria (MALB), creatinine (Cr), total cholesterol
(TC), triglyceride (TG), and low-density lipoprotein-cholesterol (LDL-C) concentrations, and also
could down-regulate expression of IL-6, MDA and AGEs, up-regulate the expression of SOD in
HN rats; HE staining and PAS staining demonstrated that AC extracts could alleviate the histopathological
changes in HN rats; western blotting demonstrated that AC extracts could up-regulate
the expression of PPARγ and down-regulate the expression of TGFβ1 and NF-кB in HN rats.
Conclusion: The finding of the article demonstrated that AC extracts had the better therapeutic
effect for HN, and provided the pharmacological evidences for AC extracts treatment for HN.
