Background: The roots of Cirsium japonicum var. ussuriense (RCJ) have been used as traditional medicine in Korea for hematuria and hematemesis. These extracts exert anti-oxidative and anti-inflammatory effects by scavenging for free radical and regulating the inflammatory response. However, the effect of RCJ on rheumatoid arthritis (RA) has not been elucidated. Thus, we evaluated the water extract of RCJ (WRCJ) using type II collagen-induced RA models. Methods and Results: RA was induced by immunization with type II collagen. All experimental materials were orally administered daily for three weeks. The positive control group was administered with 0.2 ㎎/㎏ methotrexate (n = 7), while the experimental group was administered with WRCJ (100 or 500 ㎎/㎏, n = 7). Serum levels of TNF-alpha, Interleukin 6 (IL-6), and type II collagen IgG (CII) were measured using ELISA. Administration of 500 ㎎/㎏ WRCJ decreased the levels of TNF-alpha, IL-6, and CII. Moreover, WRCJ treatment diminished swelling of hind legs and infiltration of inflammatory cells in RA models’ synovial membrane. Conclusions: These results indicate that WRCJ could improve RA, reduce inflammatory indicators and synovial inflammation. However, further experiments are required to determine how WRCJ can influence the signal transduction pathway in RA.

Background: Galgeun-tang used in traditional Korean medicine, is a mixture of the medicinal plants Cinnamomi Ramulus, Ephedrae Herba and Puerariae Radix, and has been prescribed for the treatment of various ailments, including fever. Although the use of traditional medicinal herbs to treat diseases has recently increased, their safety and toxicity profiles incompletely elucidated. Thus, we evaluated Galgeun-tang’s toxicity in male and female Sprague-Dawley rats. Methods and Results: Galgeun-tang (1,000, 2,000 and 4,000 ㎎/㎏) was orally administered to rats for 13 weeks, and then, they were maintained for 4 weeks without administration (recovery period). Their clinical signs, and hematological and urinary properties, were monitored. The results showed that Galgeun-tang administeration slightly increased serum creatinine, urea nitrogen and, aspartate aminotransferase levels. Additionally, 2,000 and 4,000 ㎎/㎏ Galgeun-tang significantly increased urinary bilirubn and protein levels of male and female rats, which were restored during the recovery period. Conclusions: The no-observed-adverse-effect level of orally administered Galgeun-tang was 4,000 ㎎/㎏ in both female and male rats, and no target organs were identified. In addition, 400 ㎎/㎏ was found to be the no-observed-effect level for toxicity under the study conditions.
