Objectives : The objective of this study was to investigate the protective effect of Flaxseed oil and Chrysanthemi Indici Flos 50% ethanol extract in an HCl/ethanol induced acute gastritis model. Methods : ICR mice were divided into 6 groups; normal mice (Nor), gastritic mice with distilled water (Veh), gastritic mice with 10 mg/kg sucralfate (SC), gastritic mice with 16 g/㎏ Flaxseed oil (FO), gastritic mice with FO + 50 mg/kg Chrysanthemi Indici Flos (FCL), and gastritic mice with FO + 100 mg/kg Chrysanthemi Indici Flos (FCH). Then, mice were orally administered with 150 mM HCl/60% ethanol and caused acute gastritis. After 1 hr, mice were sacrificed, and blood and stomach tissue were collected. Results : Administration of FCL and FCH to mice prior to the induction of gastritis was found to reduce gastric injury. reactive oxygen species (ROS) and peroxy nitrite ($ONOO^-$) levels of stomach tissues were significantly decreased in FO, FCL, and FCH compared to Veh group. As results of stomach protein analyses, FCL and FCH effectively reduce inflammatory-related factors such as inducible nitric oxide synthase (iNOS), interleukin-6 (IL-6), and interleukin 1 beta ($IL-1{\beta}$) in gastric lesion mice. In addition, nuclear factor kappa B p65 ($NF-{\kappa}B$ p65) and phosphorylation inhibitor of nuclear factor kappa $B{\alpha}(p-I{\kappa}B{\alpha})$ were down-regulated in FCL and FCH administrated gastric lesion mice. Conclusions : These results suggest that FCL and FCH has an inhibitory effect against gastric injury. Therefore, FCL and FCH has the potential to be used as a natural therapeutic drug.

Objective : Chronic acid reflux esophagitis (CARE), one of gastroesophageal reflux disease (GERD) is increasing worldwide. Coptidis rhizoma extract (CRE) is a traditional herb that cures a variety of diseases. This study was conducted to evaluate the protective effect of CR on rats with chronic acid reflux esophagitis. Methods : The antioxidant activities were evaluated through radical scavenging assays using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazolin-6-sulfonic acid) (ABTS) radical scavenging assays. CARE was surgically induced in 5-week-old male SD rats by ligating the border between forestomach and glandular portion with a 2-0 silk tie and covering the duodenum using 18-Fr $N{\acute{e}}laton$ catheter. To evaluate the esophageal protective effect of CRE, rats were divided into 3 groups: Nor (normal rats), Veh (chronic acid reflux esophagitis induced rats), CR (chronic acid reflux esophagitis induced rats treated with CRE 200 mg/kg body weight). Results : The administration of CRE significantly prevented the mucosal injury of the esophagus tissue and histological findings improved the esophageal lesion. It has been shown that inflammation is prevented by the increase of antioxidant-related factors (Nrf-2, HO-1, SOD, catalase, and GPx-1/2) through the antioxidant pathway of esophageal tissue. The administration of CRE reduced the increase of serum peroxynitrite ($ONOO^-$) and markedly reduced the protein expression of inflammatory mediator such as $NF-{\kappa}Bp65$, $p-I{\kappa}B{\alpha}$, iNOS, and IL-6. Conclusions : Overall, these results suggest that CRE administration confirmed the protective effect of esophageal mucosa, suggesting that it is a potential treatment for chronic acid reflux esophagitis.

Objectives The purpose of this study was to evaluate the antioxidant, anti-inflammatory and wound healing effects of Samul-tang-ga-dansam water extract (SD) in wound-induced mice. Methods The mice were divided into five groups (n=7): the normal group, the control group, the positive control group, the low-dose SD group and the high-dose SD group. The normal group had no wounds and the other groups were wounded on the back with a leather punch. Distilled water was administered to the control group, 200 mg/kg of vitamin E was administered to the positive control group. In the low-dose SD group and the high-dose SD group, 1.23 g/kg and 2.47 g/kg of SD were administered, respectively. Antioxidant and anti-inflammatory protein levels were evaluated using western blot analysis. Skin tissue was analyzed by H&E, Masson's trichrome staining method. Results Oral administration of the SD significantly reduced the visible skin damage and decreased the reactive oxygen species and ONOO^- activity of the serum. It significantly increased heme oxygenase-1, superoxide dismutase, catalase, GPx-1/2, Nrf2 and Keap-1 which are antioxidant-related factors in skin tissue and reduced NF-κB p65, inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor α, interleukin (IL)-1β, IL-6 which are inflammation-related factors. Also, SD significantly decreased NOX2, p22^phox and p47^phox and increased α-smooth muscle actin and COL1A1 protein expression in fibroblasts involved in connective tissue repair. According to histological examination, the thickened epithelial layer was thinned and collagen fibers were increased to accelerate wound healing. Conclusions It is suggested that Samul-tang-ga-dansam has antioxidant and anti-inflammatory effects and promotes wound tissue repair.

본 연구에서는 중강도 운동을 한 비만 흰쥐를 대상으로 정향 투여에 따른 염증 관련 단백질, 근육 합성 및 분해 관련 단백질에 미치는 영향을 평가하였다. 규칙적인 중강도 운동은 혈청 내 산화 스트레스와 leptin 수준을 억제시켰다. 또한, 염증 관련 단백질을 감소시켰으며, 근육 합성 관련 단백질을 활성화 및 근육 분해 관련 단백질 억제를 통해 근육 대사를 조절하였다. 여기에 정향의 투여는 혈청 내 염증성 사이토카인 IL-1β를 유의적으로 감소시켜 염증을 효과적으로 개선하는 효과를 발휘하였다.
