  • 유전에 의해 비만증을 타고나는 비만쥐 (ob/ob mouse)의 간으로 부터 유리된 세포막과 핵의 $L-triiodothyronine(T_3)$ 결합 능력이 그들과 한 배에서 태어난 정상 체중의 쥐들의 것들과 비교되었다. 세포막이 hypotonic 용액과 discontinuous sucrose density를 사용하여 원심분리기로 분리되었으며, 세포 각 부분의 marker enzyme들의 activity로 세포막의 순도가 측정되었다. 핵은 $Triton{\times}100$를 사용하여 윈심분리기로 얻어졌다. $T_3$ 수용체의 Bmax(최대결합용량)와 Kd(dissociation constant)가 세포막 혹은 핵을 여러 농도의 $^{125}I-T_3$와 함께 일정시간 incubation 시킨 후, 그 binding이 reverse Scatchard analysis에 의하여 계산하여 얻어졌다. 모든 실험과정은 비만쥐와 정상쥐에 대하여 평행으로 진행되었다. 간 핵의 $T_3$ 수용체의 최대결함용량은 비만쥐가 정상 체증의 쥐 보다 유의적으로 적었으나(p<0.001), $T_3$에 대한 친화력에는 차이가 없었다. 이는 이전의 보고들의 결과를 확인해 주는 것이다. 세포막에 있는 $T_3$ 수용체의 최대결합 능력과 친화력은 비만쥐와 정상쥐 간에 유의적인 차이가 없는 것으로 밝혀졌다. 이는 비만쥐의 세포막에 있는 $T_3$수용체의 기능에는 결함이 없음을 나타내며, 비만쥐의 말초조직에서 손상된 갑상선 홀몬의 작용은 세포막 수용체에 결합한 이후에 일어나는 과정에 원인이 있다는 것을 의미하고, 따라서 핵에 있는 $T_3$수용체의 결함이 비만쥐 (ob/ob mouse)의 비만증의 근본적인 원인일 수 있다는 제안을 뒷받침하여 주고 있다.

  • Objectives: This study was designed to investigate the anti-obesity, anti-diabetic and anti-inflammatory effects of Platycodi radix on obese type 2 diabetes mouse model. Methods: Obese type 2 diabetes mouse model was induced by Surwit's high fat, high sucrose diet for 8 weeks. Models were divided into 4 groups of normal diet (ND, n=10), high fat and high sucrose diet (HFD, n=10), high fat and high sucrose diet with Platycodi radix (PR, n=10), and high fat and high sucrose diet with Metformin (Met, n=10). Body weights were measured every week. After 7 weeks fasting, blood sugar and oral glucose tolerance tests were conducted. After 8 weeks blood samples were taken from mouse hearts and analyzed biochemically. Lipid profile, fructosamine, leptin and weight of epididymal fat pad and liver were measured. Adipose tissue macrophage percentage was analyzed by fluorescence-activated cell sorting (FACS). Results: Compared with the HFD group, body weight, glucose level, fructosamine, weight of epididymal fat pad and adipose tissue macrophage percentage decreased in the PR group. Conclusions: These results suggest that Platycodi Radix has anti-obesity, anti-diabetic, and anti-inflammatory effects on obese type 2 diabetes mouse model.

  • Objectives : Obesity is an important cause of diabetes, and lipotoxicity causes insulin resistance. In this study, we investigated the effects of Salvia miltiorrhiza on high fat diet-induced obese type 2 diabetic mouse models. Methods : Diabetes was induced in ICR male mouse (23~25 g) with Surwit's high fat, high sucrose diet. Mice were divided into 4 groups (n=10) of normal, control, Salvia miltiorrhiza, and metformin. After 8 weeks, body weight, OGTT, fructosamine, lipid profile, serum level of adiponectin and leptin, epididymal fat pad, liver weight and epididymal adipocyte size were measured. Results : Salvia miltiorrhiza significantly reduced oral glucose tolerance levels, fructosamine serum level, epididymal fat weight, and epididymal adipocyte size. Salvia miltiorrhiza also increased HDL-cholesterol, adiponectin and leptin serum levels. Conclusions : These results show that Salvia miltiorrhiza improves insulin resistance. Therefore we suggest that Salvia miltiorrhiza would be an effective treatment for obese type 2 diabetic patients.

  • Sjögren syndrome (SS) is a systemic inflammatory autoimmune disease that involves exocrine glands. Shikonin is extracted from comfrey, which is conventionally used as an anti-tumor, antibacterial, and antiviral drug in China. However, the application of Shikonin in SS remains unreported. This study aimed to verify the potential functions of Shikonin in SS progression. Firstly, non-obese diabetic mice were used as the SS mouse model, with C57BL/6 mice serving as the healthy control. It was demonstrated that the salivary gland damage and inflammation were aggravated in the SS mouse model. Shikonin improved salivary gland function decline and injury in the SS mouse model. Moreover, Shikonin reduced inflammatory cytokines and immune infiltration in the SS mouse model. Further experiments discovered that Shikonin attenuated the MAPK signaling pathway in the SS mouse model. Lastly, inhibition of the MAPK signaling pathway combined with Shikonin treatment further alleviated the symptoms of SS. In conclusion, Shikonin ameliorated salivary gland damage and inflammation in a mouse model of SS by modulating the MAPK signaling pathway. Our findings indicate that Shikonin may be a useful drug for SS treatment.

  • This study was to investigate the effects of high-fat diet feeding for a very long period of time on gene expression of inflammatory cytokines in mouse adipose tissue and to determine whether caloric restriction (CR) or insulin sensitizer treatment changes the cytokine gene expressions even in obese mice fed a high-fat diet for a very long term-period. Gene expression levels of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-6 (IL-6), and monocyte chemoattractant protein-1 (MCP-1) were examined by real-time PCR in subcutaneous abdominal adipose tissue (SubQ) from obese and non-obese male C57BL/6 mice at 16, 26, 36, 47, and 77 weeks of age on either normal diet (ND) or high-fat diet (HFD) after starting at 6 weeks of age. In addition, gene expression levels of TNF-${\alpha}$, IL-6 and MCP-1 were determined in SubQ before and after rosiglitazone treatment or CR on 47-week-old obese mice. The results demonstrated that gene expression levels of TNF-${\alpha}$, IL-6 and MCP-1 were significantly increased with aging in SubQ of mice in both groups of diet. MCP-1 gene expression of SubQ in all ages tested was significantly or marginally increased in mice on HFD compared with ND. While TNF-${\alpha}$ expression was significantly reduced by rosiglitazone, IL-6 and MCP-1 were significantly decreased by CR. The basic data in this study will be useful for characterizing the C57BL/6 mouse as an animal model of obesity induced by high-fat diet feeding for a very long period of time, and a better understanding of inflammatory cytokine regulation in diet induced obesity which may facilitate the development of new therapeutic strategies to prevent the complications of obesity.
