Objectives: The purpose of this study was to investigate anti-obesity effect of Scutellariae Radix extract combined with metformin. Methods: Male C57BL/6 mice, 4 weeks of age, were used to set high-fat diet induced obesity model. They were grouped NOR (normal control), HFD (high fat diet control), MET (metformin, 100 mg/kg/day), MH2 (metformin 50 mg/kg/day+Scutellariae Radix 200 mg/kg/day), and HG4 (Scutellariae Radix 400 mg/kg/day). MET, MH2, and HG4 were orally administered for 10 weeks. Body weight was measured every week. Fasting blood glucose, triglyceride, total cholesterol (TC), high density lipoprotein, glutamic oxaloacetic transaminase (GOT), and glutamic-pyruvic transaminase (GPT) were measured before sacrifice. Oral glucose tolerance test (OGTT) was also performed. Organ weight and internal fat weight were measured after sacrifice. Results: MH2 group showed a reduction of body weight when compared with HFD group. MH2 group showed stable blood level control which was calculated areas under the curves by OGTT. TC, GOT, GPT level, internal fat, and organ weight in MH2 group reduced. Conclusions: The combined treatment of Scutellariae Radix and Metformin has impact on treating obesity. Further studies are needed to evaluate the effect of Metformin and herbal medicine combination therapy.

Objective: Polycystic ovary (PCO), a diagnostic component of polycystic ovary syndrome (PCOS), requires either an ovarian volume (OV) criterion or a follicle number per ovary (FNPO) criterion. This study investigated the association of OV and FNPO criteria with various manifestations of PCOS. Methods: This cross-sectional study was conducted at a university hospital among 100 patients newly diagnosed with PCOS (according to the revised Rotterdam criteria). Fasting blood samples were collected to measure glucose, total testosterone (TT), luteinizing hormone (LH), follicle-stimulating hormone (FSH), lipid, insulin, and hemoglobin A1c levels. An oral glucose tolerance test was performed. Transabdominal or transvaginal ultrasound of the ovaries was done, depending on patients' marital status. All investigations were conducted in the follicular phase of the menstrual cycle. OV >10 mL and/or FNPO ≥12 indicated PCO. A homeostasis model assessment of insulin resistance (IR) value ≥2.6 indicated IR, and metabolic syndrome (MS) was defined according to the international harmonization criteria. Results: Seventy-six participants fulfilled the OV criterion, 70 fulfilled the FNPO criterion, and 89 overall had PCO. Both maximum OV and mean OV had a significant correlation with TT levels (r=0.239, p=0.017 and r=0.280, p=0.005, respectively) and the LH/FSH ratio (r=0.212, p=0.034 and r=0.200, p=0.047, respectively). Mean OV also had a significant correlation with fasting insulin levels (r=0.210, p=0.036). Multivariate binary logistic regression analysis showed that IR (odds ratio [OR], 9.429; 95% confidence interval [CI], 1.701 to 52.271; p=0.010) and MS (OR, 7.952; 95% CI, 1.821 to 34.731; p=0.006) had significant predictive associations with OV alone, even after adjustment for age and body mass index. Conclusion: OV may be more closely related to the androgenic and metabolic characteristics of PCOS than FNPO.

Objective: The aim of the present study was to evaluate the associations between hematologic parameters related to systemic inflammation and insulin resistance-associated metabolic parameters in women with polycystic ovary syndrome (PCOS). Methods: Eighty-two women between the ages of 18 and 35 years who were diagnosed with PCOS were included in this study. A 2-hour 75-g oral glucose tolerance test (OGTT) was administered to all study participants; fasting and postprandial glucose and insulin levels were measured simultaneously during the 2-hour OGTT. Hematologic parameters were derived from a standard complete blood count and a differential count of fasting-state blood samples. The correlations between hematologic parameters and insulin resistance-associated clinical and metabolic parameters were evaluated using the Spearman rank correlation and partial correlation coefficients. Hematologic parameters related to systemic inflammation were compared between the two groups, categorized by the presence or absence of insulin resistance. Results: Significant differences in the absolute neutrophil count, absolute monocyte count, platelet count, and neutrophil-lymphocyte ratio were found between the insulin-resistant group and insulin-nonresistant group. Correlation analysis found that all hematological parameters, except for the platelet-lymphocyte ratio, were associated with at least one insulin resistance-associated metabolic parameter. However, these significant correlations between hematological and metabolic parameters were attenuated after controlling for the effects of other covariates using partial correlation analysis. Conclusion: The association between hematologic parameters indicative of systemic inflammation and insulin resistance-associated metabolic parameters seems to be strongly influenced by other anthropometric covariates in women with PCOS.

본 연구는 8주 동안 건강한 성인남녀를 대상으로 설탕과 자일로 올리고당 함유비율이 다른 설탕 2종의 혈당 반응을 통한 GI를 비교하여 혈당 저하 효과를 확인하였다. 설탕의 GI는 68.9로 기존의 선행연구에서의 GI와 유사하였다. Xylo 7 (Xylooligosaccaride X2~X7 7% 함유), Xylo 10 (Xylooligosaccaride X2~X7 10% 함유)은 포도당이나 설탕에 비해 섭취 후 최대 혈당 상승량이 낮았으며, Xylo 7과 Xylo 10은 통계적으로 유의하게 최대 혈당 상승량이 적었다. Xylo 7와 Xylo 10의 GI는 각각 54.7, 52.5으로 모두 저GI식품에 해당하여 일반 설탕과 비교하여 혈당상승을 유의하게 억제하였다. 또한 체지방률이 높을수록 Xylo 10의 섭취는 GI를 더 낮추는 경향이었다. 따라서 자일로올리고당 유효성분 X2~X7을 함유한 설탕은 혈당상승을 억제하는 건강 기능성을 갖춘 것으로 사료된다.

꾸지뽕잎으로 제조한 덖음차(PM)와 발효차(FM)의 $\alpha$-glucosidase 저해활성과 경구 내당성 및 stereptozotocin(STZ)으로 유발한 고혈당 쥐의 혈당, fructosamine 및 혈청 지질 함량에 미치는 영향을 조사하였다. 70% ethanol 추출물(20 mg/mL)의 $\alpha$-glucosidase 저해 활성은 FM 92.5%, RM 54.6%, 건조꾸지뽕잎(RM) 69.1%였다. 경구 내당성을 조사한 결과, 고혈당 대조군은 360분까지 혈당의 감소가 없었으나 PM 및 FM을 투여한 군에서는 투여 후 60분부터 감소하여 120분 후에는 정상군 수준으로 회복되었다. 당뇨 유발 후 동결 건조한 차분말을 3% 혼합한 식이로 5주간 사육한 결과, PM 및 FM 투여군은 고혈당 대조군에 비하여 다음과 같은 효과가 있었다. 체중 증가량, 식이효율은 유의적으로 높았으며, 식이 및 음용수 섭취 량은 각각 $12.9{\sim}16.9%$ 및 $6.8{\sim}10.1%$가 감소하였다. 혈당과 fructosamine 함량은 각각 $27.3{\sim}39.8%$ 및 $6.7{\sim}20.0%$가 감소하였다. 혈청중성지질, total cholesterol 및 LDL-cholesterol 함량은 각각 $24.9{\sim}27.1%$, $15.9{\sim}17.4%$ 및 $33.8{\sim}38.4%$ 감소하였다. HDL-cholesterol함량은 $20.5{\sim}24.8%$가 증가하였다. 이러한 효과는 PM보다 FM이 다소 양호하였다. 이상의 결과, 꾸지뽕잎차의 항당뇨 효과는 $\alpha$-glucosidase 저해 활성과 더불어 고혈당에 기인된 혈청 지질의 변화를 저해함으로써 나타난 것으로 생각되나 보다 구체적인 mechanism에 대하여 앞으로의 연구가 요망된다.

The objective was to investigate the hypoglycemic action of catalpol in spontaneous diabetes db/db mice. 40 db/db mice were randomly divided into five groups: model control gourp; db/db plus catalpol 40, 80, 120 mg/kg body wt. groups and db/db plus metformin 250 mg/kg group. Age-matched db/m mice were selected as normal control group. The mice were administered with corresponding drugs or solvent by gavage for 4 weeks. The oral glucose tolerance test was carried out at the end of $3^{rd}$ week. After 4 weeks of treatment, the concentrations of fasting blood glucose (FBG), glycated serum protein (GSP), insulin (INS), triglyceride (TG), total cholesterol (TC) and adiponection (APN) in serum were detected. The protein expressions of phosphorylation-$AMPK{\alpha}$1/2 in liver, phosphorylation-$AMPK{\alpha}$1/2 and glucose transporter-4 (GLUT-4) in skeletal muscle and adipose tissues were detected by western blot. Real time RT-PCR was used to detect the mRNA expressions of acetyl-CoA carboxylase (ACC) and Hydroxymethyl glutaric acid acyl CoA reductase (HMGCR) in liver. Our results showed that catalpol could significantly improve the insulin resistance, decrease the serum concentrations of INS, GSP, TG, and TC. The concentrations of APN in serum, the protein expression of phosphorylation-$AMPK{\alpha}$1/2 in liver, phosphorylation-$AMPK{\alpha}$1/2 and GLUT-4 in peripheral tissue were increased. Catalpol could also down regulate the mRNA expressions of ACC and HMGCR in liver. In conclusion, catalpol ameliorates diabetes in db/db mice. It has benefit effects against lipid/glucose metabolism disorder and insulin resistance. The mechanism may be related to up-regulating the expression of phosphorylation-$AMPK{\alpha}$1/2.

Objective: This study was performed to investigate the effects of pioglitazone, an insulin sensitizing agent, on insulin resistance, ovarian function and intraovarian stromal blood flow in patients with polycystic ovarian syndrome (PCOS). Material and Methods: Thirty patients with PCOS, aged 18~34 years, were recruited. Criteria for diagnosis of PCOS were as defined in 2003 Rotterdam consensus. They were treated for 6 months with pioglitazone at a dose of 30 mg/day orally. The hormonal blood profile, fasting serum glucose levels, a glycemic response to 75 g oral glucose tolerance test (OGTT), and an ovarian stromal artery (OSA) blood flow were assessed at baseline and after 6 months of treatment. Results: Eighteen (60.0%) of 30 patients treated with pioglitazone demonstrated a spontaneous ovulation After pioglitazone treatment, fasting insulin concentrations, serum glucose levels after 75 g OGTT significantly decreased (p=0.001, p=0.04, respectively), and fasting glucose to insulin (G/I) ratio significantly increased (p<0.001). The pioglitazone treatment induced a significant reduction in serum LH, testosterone (T) and free T levels (p<0.001, p=0.02, p=0.002, respectively). The resistance index (RI) values of OSA significantly increased after treatment (p<0.001). In analyzing pioglitazone-treated patients according to their body mass index (BMI), nonobese group as well as obese group showed a significant improvement in fasting G/I ratio (p<0.01). The pioglitazone treatment induced a significant reduction in serum LH and free T levels in nonobese group (p<0.001, p<0.05, respectively) as well as obese group (p=0.001, p<0.05, respectively). The RI values of OSA significantly increased in both nonobese and obese groups after pioglitazone treatment (p<0.001, p=0.003, respectively). Conclusions: Pioglitazone could ameliorate the glycoinsulinemic metabolism, and this beneficial effects of this drug could improve the endocrine-reproductive condition associated with the decrease of ovarian stromal artery blood flow, in both nonobese and obese patients with PCOS.
