초록

본 연구는 까마귀쪽나무열매추출물(LJF-HE)이 흰쥐모델에서 스트레스로 유발되어지는 위염에 대한 억제효과를 확인하고자 하였다. 이때 까마귀쪽나무열매추출물(LJF-HE)소재는 지표성분인 hamabiwalactone B의 함량이 $15.23{\pm}0.057mg/g$로 규격에 적합한 것을 사용하였다, 동물실험에 있어 군분리는 정상군(normal), 양성 대조군(control, 수침 구속 스트레스 위염 유발), 약물 대조군(ranitidine, 50 mg/kg), 까마귀쪽나무열매추출물 저농도 투여군(LJF-HE-L, 30 mg/kg), 까마귀쪽나무열매추출물 중농도 투여군(LJF-HE-M, 60 mg/kg), 까마귀쪽나무열매추출물 고농도 투여군(LJF-HE-H, 120 mg/kg)의 총 6군으로 구성하여 실험을 진행하였다. 그 결과 까마귀쪽나무열매추출물의 투여그룹(LJF-HE-L, LJF-HE-M, LJF-HE-H)에서 염증의 길이가 control 그룹에 비하여 통계적으로 유의하게 감소하였으며, 육안 병변 관찰에서도 까마귀쪽나무열매추출물(LJF-HE) 투여그룹에서의 위 염증과 점막출혈 부위가 control 그룹에 비하여 감소하였음을 관찰할 수 있었다. 또한 까마귀쪽나무열매추출물(LJF-HE) 투여그룹에서의 펩신 활성도도 control 대비 유의성 있게 감소하는 것으로 나타나 까마귀쪽나무 열매추출물은 펩신 활성도를 낮춰 위염 발생을 억제하는 것으로 사료된다. 그리고 까마귀쪽나무열매추출물의 투여 그룹(LJF-HE-M, LJF-HE-H)에서 gastrin에 의해 활성화 되는 CCK-2r 유전자 발현이 대조군에 비해 유의적으로 억제되는 것으로 나타났으며, 염증성 cytokine중에 하나인 IL-$1{\beta}$의 혈장 내 함량이 대조군에 비해 유의적으로 감소하였고, 세포보호물질로 점액 및 혈류량을 증가시켜 위점막을 보호하는 역할을 하는 PGE2의 혈장 내 함량이 대조군에 비해 유의적으로 증가한 결과를 얻었다. 이와 같은 결과는 까마귀쪽나무열매추출물(LJF-HE)이 스트레스로 유발되어지는 위염에 대한 억제효과가 있음을 확인하였다.

The object of this study was to investigate the inhibitory effects of Litsea japonica fruit flesh extract (LJF-HE) on gastritis of an stress-induced SD rat model. Rats were randomly divided into six groups: Normal (normal group), Control (stress-induced gastritis), Ranitidine (stress-induced gastritis and ranitidine 50 mg/kg), LJF-HE-L (stress-induced gastritis pretreated with L. japonica fruit flesh extract at 30 mg/kg), LJF-HE-M (stress-induced gastritis pretreated with L. japonica fruit flesh extract at 60 mg/kg), LJF-HE-H (stress-induced gastritis pretreated with L. japonica fruit flesh extract at 120 mg/kg). In groups treated with LJF-HE, gastric mucosal damage and pepsin activity were reduced. Additionally, there were decreases in the expression of cholecystokinin 2 receptor (CCK-2r) in the gastric lesions. The plasma levels of IL-$1{\beta}$ slightly but significantly decreased in LJF-HE treated groups compared to control. The plasma level of PGE2 was also significantly increased in LJF-HE treated groups. These results suggest that LJF-HE has the ability to reduce of the severity stress-induced gastritis.
