The Anti-Inflammatory Effect of Gabyeobda Tea in High Fat Diet-Induced Obese Mice

Objectives: The purpose of this study was to investigate the effects of Gabyeobda tea (GT) on anti-inflammation in ice induced high fat diet (HFD). Methods: The C57BL/6 mice fed HFD were administrated with GT once daily for 8 weeks. The changes of body weight, calorie intake levels were measured in mice. The level of serum total cholesterol, triglyceride, high density lipoprotein cholesterol, glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPT) were measured in mice by enzyme-based assay. It was also observed the histological changes of liver, and fat tissues with hematoxylin and eosin staining. Further real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay were employed to detect inflammatory cytokine levels such as tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β. Results: HFD+GT group, which was administered with GT with HFD, showed no body weight gain compared with HFD group. However, levels of GOT, GPT, and inflammatory cytokines such as TNF-α, IL-6, and IL-1β in the blood of HFD+GT group were significantly reduced compared with HFD group. In addition, the messenger RNA (mRNA) expression level of the IL-12 gene was significantly reduced and the mRNA expression level of the IL-10 was increased in the liver. Conclusions: It suggests that Gabyeobda tea can alleviate inflammatory responses induced by high fat diet by inhibiting inflammatory cytokines production.
