  • Voglibose is a new antidiabetic agent currently being devoloped by the research and development division of Takeda chemical industries Ltd. in japan. Basic research for the determination of voglibose in pharmaceutical preparation by gas chromatography. This method utilizes voglibose to give its acyl compound with acetyl anhydride in pyridine solution. The calibration curve for voglibose was linear over the concentration range of 0.08∼0.32 $\mu\textrm{g}$/${mu}ell$ with correlation coefficient of 0.996. The detection limit for voglibose was 0.016 $\mu\textrm{g}$/${mu}ell$ and the result of recovery test was 101.6% with relative standard deviation of 2.0% by standard addition method.

  • The methanol extract of seeds of Swietenia macrophylla King. (MESM) was studied for its antidiabetic activity in streptozotocin induced diabetic rats. It was principally aimed to correlate the efficacious role of MESM on reduction of oxidative state associated with diabetes. The extract was found to be potent antidiabetic evidenced by significant reduction of blood glucose level in diabetic rats (47.96% reduction of blood glucose level, at 300 mg/kg, on day 10). It was found that, MESM at 300 mg/kg, significantly decreased TBARS (35.03 and 22.22%) whilst increased GSH (86.75 and 31.45%), SOD (93.05 and 45.88%) and CAT (56.99 and 68.46%) levels in liver and kidney respectively in diabetic rats.

  • (R)-JG-381, a R form of alkylglycidic acid derivative, was examined for mutagenicity in the reverse mutation test on bacteria, chromosomal aberration test on cultured mammalian cells and micronucleus test in mice. In the reverse mutation test on bacteria using Salmonella typhimurium strain TA98, TA100, TA102, TA1535, TA1537 with or without a metabolic activation system (S9 mix), (R)-JG-381 did not affect the revertant colonies but significantly increased revertant colonies in one test strain, TA98, compared with the vehicle control. In the chromosomal aberration (CA) test using cultured Chinese Hamster Lung fibroblast(CHL) cells, the number of aberrant cells was clot increased in the presence or absence of 59 mix at concentration of the (R)-JG-381 0.025 $\mu$l/m1 to 0.1 $\mu$l/m1, compared with vehicle control. In the micronucleus (MN) test, micronucleated polychromatic erythrocytes in the (R)-JG-381-treated mice were not different from those of the vehicle-treated mice.

  • In order to investigate the usability of PALMIWON as antidiabetic immuno-modulating prescription for Insulin-dependent diabetes, we studies the effects of PALMIWON on immune cell and ${\beta}-cell$. U937 was used as the model of immune cell and RINm5F as the model of ${\beta}-cell$. The effects of PALMIWON was measured by cell viability in terms of MIT assay. As a result, PALMIWON and the compositional drugs showed the different effects m immune cell and ${\beta}-cell$. Cell viability of U937 was significantly decreased wheras that of RINm5F was no significantly difference between drug treated group and control, or significantly less reduction compared with U937. It implies that PALMIWON is useful as immunotherapeutic agents in the prevention and therapy of type 1 diabetes.

  • Antidiabetic activity of formular containing an Euonymus alata (EA) and Mori Foluim (MF) was investigated in oral glucose tolerance test (OGTT) and multiple low dose Streptozotocin (MLDSTZ)-induced rats. Optimum ratio between EA and MF was found to be 1:1 in OGTT, and two strengths (250 and 500 mg/kg for each medicinal plant) were coadministered with 20 mg/kg of STZ in 5 consecutive days. At 3rd week, water and food intakes were compared between groups and polydipsia and polyphagia shown in diabetic control were markedly improved in dose dependent manner. (omitted)

  • 본 연구에서는 스트렙토조토신(Streptozotocin,STZ)으로 유발된 당뇨쥐에게 맥문동(Liriope platyphylla,Lp)에탄올 추출물(수율:30.7%)을 1,000mg/kg용량으로 7일간 경구 투여 후 혈청속의 혈당함량과 당대사와 관련된 몇 몇 효소와 지질대사와 관련된 물질을 측정한 결과 혈당과 triglyceride(TG), total cholesterol의 농도는 STZ대조군과 비교하여 맥문동 투여군에서 유의적인 감소를 나타내었고, glucose-6-pase(g-6-pase)활성은 STZ 대조군과 비교하여 유의적인 감소를, glucokinase(gk)활성은 증가를 나타내었다. 또한 hepatic glycogen 함량은 STZ대조군과 비교하여 유의적인 증가를 나타내었다. 따라서 본 실험 결과 맥문동 에탄올 추출물을 스트렙토조토신으로 유발된 당뇨쥐에 있어서 항 당뇨 성분을 함유하고 있음을 알 수 있었다.

  • Objectives : Recently a lot of research is being done for find antidiabetic medicine which has no side effects. This study aimed to investigate the antidiabetic and antiobesity effects of Supungsunki-hwan partitioned prescriptions on obese type 2 diabetes mouse. Methods : Type 2 diabetes mellitus and obesity were induced by Surwit's high fat, high sucrose diet for 8 weeks. Mice were divided into 3 groups of ND (normal diet, n=10) HFD (high fat and high sucrose diet, n=10) and SPP (high fat and high sucrose diet with Supungsunki-hwan partitioned prescriptions, n=10) groups. Body weights were measured every week. After 7 weeks, fasting blood sugar and oral glucose tolerance tests were conducted. After 8 weeks, blood samples of all mice were taken from their heart and analyzed biochemically. At the same time, epididymal fat pad and liver weights were measured. Histological size of white adipocyte were measured as well. Results : Compared with a HFD group, body weight, fructosamine, epididymal fat pad weight and white adipocyte size decreased. High-density lipoprotein cholesterol levels increased in the SPP group. Conclusions : These results suggest that SPP has antidiabetic and antiobesity effects in high fat, high sucrose diet induced obese mice.

  • In present study, we investigated the antidiabetic effect of Momordica charantia(as well known "bitter melon"). This study was conducted to determine antidiabetic mechanism of Bitter Melon Extract (BME). We measured blood glucose, insulin, glucagon level in a Sprague-Dawley rat model of high-fat diet/streptozotocin(HFD/STZ)-induced diabetes. Five experimental groups were used: normal, HFD/STZ, BME 62.5 mg/kg HFD/STZ, BME 125 mg/kg HFD/STZ and BME 250 mg/kg HFD/STZ. BME was orally administered to the rats every other day for 9 weeks. Results showed that fasting blood glucose levels were significantly lower in the BME 125 mg/kg(150.17 ± 20.22 mg/dL) and 250 mg/kg(124.17 ± 22.17 mg/dL) groups than in the vehicle group(188.83 ± 26.63 mg/dL)(p<0.05). In addition, glucagon levels were lower in the three BME treatment groups than in the vehicle group(p<0.05). Oral glucose tolerance tests revealed that the BME 250 mg/kg group had significantly(p<0.05) reduced 120-minute blood glucose levels and areas under the curve. Our results suggest that BME induces antidiabetic effects via the reduction of glucagon and blood glucose levels.
