  • Oryeongsan (ORS), a formula composed of five herbal medicines, has long been used to treat impairments of the regulation of body fluid homeostasis. The purpose of this study was to determine the antihypertensive and renal protective effects of ORS in rats with hypertension. Spontaneously hypertensive rats (SHR) were divided into two groups with similar mean baseline systolic blood pressure (SBP). Then, 1 mL/kg of vehicle (distilled water) or 1.5, 3 g/kg of ORS extract were administered orally once a day for 4 weeks. SBP and diastolic blood pressure (DBP) were measured at weeks 1, 2, 3 and 4. At the end of the experiment, blood was collected, and heart were removed for histology. By the 2 weeks after initiation of treatment, the ORS treated group had significantly lower SBP than SHR rats. The ORS treatment significantly improved blood pressure and echocardiogram parameters compared to hypertensive rats. Additionally, the left ventricular (LV) remodeling and LV dysfunction were significantly improved in ORS treated group hypertensive rats. Furthermore, an increase in fibrotic area has been observed in SHR rats compared with Wistar-Kyoto rats (WKY). Furthermore, administration of ORS significantly attenuated cardiac fibrosis in hypertensive rats. Therefore, these findings suggest that ORS has a protective effect on heart failure by alleviating hypertensive heart disease and cardiovascular dysfunction in SHR.

  • Ureteral obstruction can be causes of renal dysfunction and renal injury at late period of kidney pathology. The purpose of this study was to determine the protective effects of Oryeongsan (ORS), Geumgwe-sinkihwan (GSH), and Jwagwieum (JGE) in rats with unilateral ureteral obstruction (UUO). The animal models were divided into five groups randomly at the age of 5 weeks; Control group: SD male rats (n=10), UUO group: SD male rats with UUO surgery (n=10), ORS group: SD male rats with UUO surgery + ORS 200 mg/kg/day (n=10), GSH group: SD male rats with UUO surgery + GSH 200 mg/kg/day (n=10), JGE group: SD male rats with UUO surgery + JGE 200 mg/kg/day (n=10). Treatment with ORS, GSH, and JGE significantly ameliorate creatinine clearance(Ccr). The present results also showed that ORS, GSH, and JGE improved the morphological aspects of renal tissues. These prescriptions also reduced the expression levels of cytokines such as TNF-α, IL-1β, and IL-6. In Kidney, UUO increased the expression levels of inflamasome markers such as NLRP3, ASC, and Caspase-1. However, ORS, GSH, and JGE suppressed these levele. Treatment with these prescriptions reduced kidney inflammation markers such as Neutrophil Gelatinase Associated Lipocalin (NGAL) and kidney injury molecule -1 (KIM-1). Therefore, these findings suggest that ORS, GSH, and JGE has a protective effect on renal injury by alleviating renal inflammation and improving renal function in rats with UUO.
