The possible effects of 10% carbohydrate containting diets on the serum glucose and lipids values were studied with normal and alloxan - diabetic male rats for a period of 28 days. The diets were supplemented with either glucose, cornstarch or sucrose, fructose or the basal diet containing no added carbohy drates. After this period, 3 to 4 rats among the each group were killed and samples of serum, liver, spleen and kidney were collected. The others were rendered diabetic by the intraperitoneal injection of alloxan (190mg/wtkg). Then original feeding scedule was continued for 3 days in all five diabetic groups, before the collection of tissue samples and serum. Feeding the nondiabetic rats with glucose and fructose delayed the bodyweight development relatively compared with nonsugar group. The weight deductions after alloxan injection were similar in all feeding groups. All diabetic animals exhibited increased blood glucose triglceride levels but almost unchanged total cholesterol values. Blood glucose values for nondiabetic rats were normal ranges, and then glucose feeding group was the highest. Total - cholesterol values were the highest in nondiabetic rats fed glucose, fructose and in diabetics fed sucrose, glucose. Triglyceride values were the highest in nondiabetic rats fed sucrose, and no difference in diabetic rats. Some cornstarch group exhibited fatty-livers in diabetic and nondiabetic, and more studies need.

The purpose of this study was to investigate the improvement effect of 5% turmeric (Curcuma longa L.) on the blood glucose and lipid metabolism function of streptozotocin (STZ, 45 mg/kg body weight)-induced diabetic rats. Seven-week-old male rats were divided into four groups (n=6), and fed experimental diets containing turmeric meal [basal diet+5% turmeric (BT), basal diet+STZ+5% turmeric (ST)], and control (BD), BS groups (basal diet+STZ). The results of this study, turmeric diet groups (BT, ST) in lipid component as evidenced from the significantly reduction of serum total cholesterol, low density lipoprotein-cholesterol (LDL-cholesterol), atherosclerotic index (AI), cardiac risk factor (CRF), triglyceride (TG), phospholipid (PL), free cholesterol, cholesteryl ester, uric acid, blood glucose, non esterified fatty acid (NEFA), and elevation of high density lipoprotein-cholesterol (HDL-cholesterol). The serum albumin and globulin contents were increased in turmeric supplementation diet than STZ-induced diabetic rats (p<0.05). Concentrations of sodium (Na) and chlorine (Cl) in sera were lower in the turmeric diet than diabetic group. Total calcium (T-Ca), phosphorus (Pi) and potassium (K) concentrations in sera were higher in the BT, ST and BD groups than BS group. In vivo experiments with Sprague-Dawley rats showed that ingestion of turmeric (Curcuma longa L.) were effective in the blood glucose and lipid metabolism functional improvement.

인구 고령화 및 서구화된 식습관, 생활습관 변화 등으로 인해 수명 연장, 만성대사성 질환의 유병율이 증가하고 있다. 또한 헬스케어 관련 제품의 구매가 활성되면서 모바일을 기반으로 한 혈당관리 모바일 App이 급속도로 발전되고 있으며, 다양한 제품들이 출시되고 있다. 하지만 병원용 혈당기는 많은 사람들을 사용함에도 불구하고 병원 시스템과 유기되어야 하고 기능의 복잡성과 제약 등으로 인하여 모바일 APP에 비해 GUI 개발이 미비한 상황이다. 따라서 본 연구에서는 기존 모바일 APP의 GUI와 병원용 혈당기 GUI를 선행연구를 통해 최적화가 반영된 병원용 혈당기가 기존 병원용 혈당기와 사용성에서 차이가 있는지도 검증하고자 한다. 분석결과, 기존 병원용 GUI 비해 최적화가 반영된 GUI가 사용성이 높은 것으로 나타났으나 만족도는 변함이 없었다. 또한 플렛 디자인은 스큐어모피즘 디자인보다 작은 화면에서 사용성에 큰 도움을 주고 있음 알 수 있었다. 이를 통해 사용자요구가 반영된 직관적이고 신뢰할 수 있는 GUI를 제공하고 이를 통해 적극적인 혈당관리를 유도하게 하는 데에 도움이 되었으면 한다.

The aim of this study is to investigate the effects of tea catechin on fasting blood glucose in experimental diabetes model. Type 2 diabetes mellitus in rats was induced by high fat diet/low-dose streptozotocin. The experimental group was divided into 3 different groups, non-diabetes control (NC) group, diabetes mellitus (DM) group, and diabetes mellitus+P60 (DM+P60) group. Polyphenon 60(P60) administered with dissolved in 0.2% dringking water. At 16 weeks after P60 treatment, fasting blood glucose, plasma insulin and serum triglyceride levels were measured. The glucose metabolism-related genes were studied in rat liver by RNA-seq analysis. Fasting blood glucose levels increase by four times in the DM group compared to the NC group. In the DM+P60 group, it was decreased by 24% compared to the DM group. The HOMA-IR index was increased in the DM group and it decreased in the DM+P60 group compared to the DM group. The serum triglyceride level increased by 148% in the NC group, and decreased by 22% in the DM+P60 group compared to the DM group. Glucokinase mRNA expression was decreased in the liver of DM group compared to NC group, whereas the phosphofructokinase 1, glucose-6-phosphotase and phosphoenolpyruvate carboxykinase expression did not show significant differences in DM group liver. In DM+P60 group, liver glucokinase expression was increased significantly (P: 5.00E-05) compared with DM group. This study shows that P60 beneficially modifies glucose metabolism and markedly enhances glucose tolerance in experimental diabetic rats. Dietary supplementation with P60 could potentially contribute to nutritional strategies for treatment of type 2 diabetes mellitus.

This study was conducted to investigate the effects of sowing density, number of seeds sown per hole, andthinning treatment on growth characteristics and disease occurrence in Panax ginseng under direct sowing cultivation in ablue plastic greenhouse. Seedling were grown from 2 or 3 seeds sown, and the healthiest was only retained, while the restwere thinned out at the foliation stage. NO3-N, P2O5, and organic matter content differed significantly between growthconditions in the plastic greenhouse and in conventional shade in the soil. Disease also tended to be higher in the conven-tional shade than in the plastic greenhouse. Plant height and stem length showed an increasing trend with increasing sowingdensity and number of seeds sown per hole. However, these measures noticeably decreased when thinning treatment wasconducted. Growth of the subterranean part of ginseng was not markedly influenced by sowing density, the number of seedssown per hole, or thinning treatment. Root weight, which is an important factor in yield, was significantly affected by thenumber of seeds sown and thinning treatment. Interestingly, root weight tended to be higher in the thinning treatment plotthan the untreated control plot. Damping-off and root rot increased noticeably as the number of seeds sown increased. Dis-ease also tended to be substantially higher in the thinning treatment plot than the untreated control. However, physiologicaldisorder of the plants did not vary with sowing density, the number of seeds sown, or thinning treatment.

This is the case report of a 58-year-old man who developed acute severe hypoglycemia after a spinal block. He had a history of injecting insulin combined with 50% dextrose for hyperkalemia control. After the spinal block, he presented with hypo-glycemic symptoms and went into convulsions. Following injection of midazolam and 10 ml of 50% dextrose, his mental state returned to alert. We recommend careful monitoring of blood sugar level of chronic kidney disease patients who under-go neuraxial block.

Stress induced cardiomyopathy is characterized by transient systolic dysfunction of the apical segment of the left ventricle, in the absence of obstructive coronary artery disease. The clinical presentation of stress induced cardiomyopathy is similar to that of an acute myocardial infarction. Onset of stress induced cardiomyopathy is frequently triggered by intense emotional or physical stress. Hypoglycemia is one type of physical stress that causes stress induced cardiomyopathy. We report on a case of this syndrome associated with hypoglycemia.

Sorghum seed is traditionally used as secondary food sources in addition to rice in Korea. While the hypoglycemia regulating phytochemicals have been found in sorghum seed, peptides related with hypoglycemia never been studied before. To obtain the peptide characteristics and the specifically high-expressed peptides in hypoglycemic sorghum seed, peptide profiles of seven hypoglycemic and five nonhypoglycemic sorghum lines bred in RDA were determined using surface-enhanced laser desorption/ionization time-offlight mass spectrometry (SELDI-TOF MS). The twelve sorghum lines exhibited 104 peptides on CM10 protein chip array (weak cation exchange) and 95 peptides on Q10 (weak cation exchange) in the molecular mass range from 2,000 to 20,000 Da. Heat map via supervised hierarchical clustering of the significantly different peptides (p < 0.01) in peak intensity among the 12 lines effectively revealed the specifically upregulated peptides in each line and distinguished between 7 hypoglycemic and 5 non-hypoglycemic lines. Through the comparison with hypoglycemic and non-hypoglycemic lines, 10 peptides including 2231.6, 2845.4, 2907.9, 3063.5, 3132.6, 3520.8, 4078.8, 5066.2, 5296.5, 5375.5 Da were specifically high-expressed in hypoglycemic lines at p < 0.00001. This study characterized seed peptides of 12 sorghums and found ten peptides highly expressed for hypoglycemic sorghum lines, which could be used as peptide biomarkers for identification of hypoglycemic sorghum.

This study was designed in order to determine the influences of haw (Crataegus pinnatifida BUNGE) on the lipid metabolism syndrome. Sprague Dawley rats, 7 weeks old, were given four different types of diets for 5 weeks: ND group (noncholesterolemic diet), HE group (non cholesterolemic diet+haw extract), CD group (cholesterolemic diet), CH group (cholesterolemic diet+haw extract). Concentrations of LDL-cholesterol, triglyceride, phospholipid, free cholesterol, cholesteryl ester, blood glucose were remarkably higher in the CD group than the other groups. But by treatment of haw extract group with cholesterolemic diet (CH group) were significantly decreased compared with CD group. Cholesteryl ester ratio was no difference between CD group and CH group. These results indicate that Crataegus pinnatifida BUNGE would be effective in lipid metabolism syndrome.

여주는 몇몇 열대지역에서 중요한 채소 작물이다. 여주 과 실이 의학적으로 효능이 있는 활성물질을 포함하고 있음에도 불구하고, 한국에서는 주로 장식용으로 이용되어 왔다. 최근 여주의 미숙과실에 있는 항당뇨성분 때문에 여주에 대한 관 심이 증가하고 있다. 그러나 재배법과 기능성성분에 대한 연 구가 거의 수행되지 않았다. 본 연구에서는 항 당뇨성분인 카란틴 성분 함량이 높은 유전자원을 선발하기 위하여 카란틴 성분을 분석하였다. 여주 과실의 카란틴 성분 분석은 31자원 의 인공교배된 착과 후 15일 경과한 과실을 이용하였다. 카란틴 함량은 15.1∼161.4 μg·g -1이었으며, 건물중은 221 ∼2,097 g이었다. ‘K169998’, ‘K042800’, ‘K170002’, ‘Hwanock’ 그리고 ‘Nockwoo’ 5개 계통의 카란틴 함량은 각각 143.7, 104.6, 103.5, 161.4, 101.1 μg·g -1이었다. 이러한 결과는 항 당뇨 성분인 카란틴 함량이 높은 여주자원 선발에 활용될 수 있으며, 안정적인 고품질 여주 자원 선발에 기초자료로 이용 될 것이다. 향후 여주의 수확시기가 어떻게 카란틴 함량 변화 에 관여하는지에 대한 기작 규명 연구가 필요하다.

The purpose of this study was to assess the effects of Cordyceps militaris extract supplementation on the improvement of blood glucose, lipid compositions and hepatic functional enzyme activities in the serum of streptozotocin(STZ, 50 mg/kg BW, IP injection)-induced diabetic rats fed the experimental diets for 5 weeks. The concentrations of blood glucose and lipid compositions(total cholesterol, β-lipoprotein, free cholesterol, cholesteryl ester, triglyceride and phospholipid) and atherosclerotic index in serum were significantly lower in the DM+CM group than in the DM group, whereas the ratio of HDL-cholesterol concentration to total cholesterol in the DM+CM group were higher than in the DM group. The activities of hepatic functional enzymes(aminotransferase, LDH and ALP) in serum were lower in the Cordyceps militaris extract administration group(group DM+CM) than in the hyperglycemic DM group. The results shown above suggested that Cordyceps militaris extract supplementation effectively improves blood glucose and atherosclerosis in the serum of diabetic rats.

To investigate the anti-diabetic activity of ethanol and aqueous peel and seed extracts obtained from three different grape species (Cambell Early, MBA, and Kyoho), alpha-glucosidase inhibitory activity was examined. All extracts showed anti-diabetic activity, especially aqueous extract exhibited inhibitory effect above 70%. Thus, we used aqueous extract to check the potential hypoglycemic effects in a streptozotocin (STZ)-induced diabetic mice model. The results showed that the blood glucose level of STZ-induced diabetic mice decreased drastically after 3 hr when the aqueous extract of Cambell Early seed was treated to the mice model. The aqueous extract of Kyoho seed lessened blood glucose level by 60%. Together, these data indicate that extracts of grape peel and seed (aqueous or ethanol) may have potential in improving hypoglycemic effects in the diabetic symptoms, suggesting that further investigation on biomarker expressions should be rewarding.
