당뇨병은 대사 증후군 및 심혈관 질환을 비롯한 다양한 건강상의 부작용과 관련이 있다. 또한 당뇨병의 증가로 사회 및 의학적 관심이 증가하고 있다. 제 2 형 당뇨병의 특징 중 하나는 혈당이 증가한다는 것이다. 공복 혈당치는 가장 기본적이고 널리 사용되는 당뇨병의 지표이다. TLR4 발현은 심장에서 비교적 높다. 그러나 공복 시 혈당과 TLR4의 관련성에 대한 연구가 있었다. 한국인에서 TLR4 유전자와 공복 시 혈당의 단일 염기 다형성(SNP)의 관련성을 알아 보았다. 서울시에서 총 994 명을 대상으로 TLR4 SNP를 이용한 연구를 실시했다. 공복 시 혈당과 관련하여 TLR4 유전자 영역은 연쇄 불균형으로 나타 났으며 유전자의 범위가 매우 크기 때문에 여러 개의 LD 블록으로 보였다. TLR4 유전자의 SNP는 평균 공복 시 혈당과 관련이 있었다(p<0.01). 공복 시 혈당과 관련 크기는 p-value를 $-log^{10}$의 값으로 하였다. rs1329067의 minor allele frequency는 16.4%였고 AA 유전자형을 가진 사람들은 GG 유전자형을 가진 사람들 보다 공복 시 혈당이 높았다. 이 연구는 TLR4의 유전 적 변이가 한국 성인의 혈당 수치에 영향을 미친다는 것을 암시한다.

Microalbuminuria is most frequently caused by kidney damage from diabetes. Moreover, many other conditions can lead to kidney damage, such as high blood pressure, heart failure, cirrhosis, or systemic lupus erythematosus (SLE). The measurement of the microalbumin in urine may be useful for the early diagnosis or as a predictor of nephropathy in diabetes. The most common method for getting a quantitative measurement of urinary protein relies on a 24-hour urine collection. The result of this method is accurate. But 24hr urine collection is difficult to obtain and variations in volume are frequent. Also the patients complain about urine collection. We tried to measure reference values for microalbumin using fasting urine and compare them with the albumin/creatinine ratio using 24hr urine. The concentrations of microalbumin in fasting urine and 24hr urine were $7.1{\pm}3.8mg/L$, $5.7{\pm}2.9mg/L$ (r=0.61, p=0.27), respectively. The albumin/creatinine ratios using fasting urine and 24hr urine were $8.7{\pm}4.2{\mu}g/mg$, $8.7{\pm}4.0{\mu}g/mg$ (r=0.76, p=0.88), respectively. This study indicated that the measurement of microalbumin in fasting urine was an easy and simple method for early diagnosis or to predict nephropathy in diabetes. Thus, setting up the reference value using fasting urine may be useful in the screening test for the diabetic nephropathy patients instead of using the 24hr albumin excretion rate (AER).

Since diet is an essential component of the treatment for diabetic mellitus, a progressive educational plan was designed to educate diabetic children for the proper selection of their foods. Seven suspicious children were chosen according to the previous oral glucose tolerance test and present blood glucose levels (fasting and postprandial 2 hours). The education program includes the basic nutrition study, learning of the five basic food groups. familiarization with the food exchange lists. calorie calculation and menu planning, and follow-up evaluation by checking every day -food intake. The duration of the education was five weeks. The levels of fasting blood glucose and postprandial -2 hours blood sugar of the seven children were significantly reduced after the 5-weeks education:FBS:from 92-125mg% to 67-80mg%, pp-2hours BS: from 130-169mg% to 69-90mg%. The children have felt much better with profound self-confidence after to program . Their oral glucose tolerance test levels were also significantly decreased after the 5-weeks education in comparison with those of one year ago.

Background: To investigate the antidiabetic effects of hydrolyzed ginseng extract (HGE) for Korean participants in an 8-wk, randomized, double-blinded, placebo-controlled clinical trial. Methods: Impaired fasting glucose participants [fasting plasma glucose (FPG) ${\geq}5.6mM$ or < 6.9mM who had not been diagnosed with any disease and met the inclusion criteria were recruited for this study. The 23 participants were randomly divided into either the HGE (n = 12, 960 mg/d) or placebo (n = 11) group. Outcomes included measurements of efficacy (FPG, postprandial glucose, fasting plasma insulin, postprandial insulin, homeostatic model assessment-insulin resistance, and homeostatic model assessment-${\beta}$) and safety (adverse events, laboratory tests, electrocardiogram, and vital signs). Results: After 8 wk of HGE supplementation, FPG and postprandial glucose were significantly decreased in the HGE group compared to the placebo group. No clinically significant changes in any safety parameter were observed. Our study revealed that HGE is a potent antidiabetic agent that does not produce noticeable adverse effects. Conclusion: HGE supplementation may be effective for treating impaired fasting glucose individuals.

The Korean GDP per capita doubled during the last 10 years. As the GDP increases, Korean health behaviors such as, eating, drinking, smoking, and exercise habits changed as well. Compared to the remarkably advanced diagnostic technologies and therapeutics during the last decade, the leading causes of death in Korea scarcely changed. Among the leading causes of death, cerebrovascular disease, heart disease, diabetes, liver disease and hypertension are closely related to health behaviors. Using the database of medical check-up between 2001 and 2010, the authors performed a longitudinal study for the prevalence rates and the trends of major chronic adult diseases among the 2,721 workers along with their health behavior. Among the diagnostic test items, fasting blood sugar, cholesterol and BMI levels showed steady increase and these three test items all showed linear trends (p<0.001). The average blood sugar and cholesterol levels were near worrying levels. Moreover, the average BMI of males was found to be at the overweight level, intimating the possibility reaching thee Obese Class I level soon if there are no aggressive counter measures. Fasting blood sugar and cholesterol levels were higher in a drinking group as compared to a non-drinking group, and the BMI levels were also higher in the drinking group and the smoking group as compared to the non-drinking and the non-smoking group (p<0.001). Finally, the authors believe that the fasting blood sugar, cholesterol and BMI levels should be designated as target monitoring test items in the medical check-up for Korean employees.

The role of surgical intervention in patients with diabetic gastroparesis is unclear. We report a case of a 37-year-old man with a history of recurrent episodes of vomiting and long-standing type 2 diabetes mellitus. Esophagogastroduodenoscopy did not reveal any findings of reflux esophagitis or obstructive lesions. A gastric emptying time scan showed prolonged gastric emptying half-time (344 minutes) indicating delayed gastric emptying. Laboratory tests revealed elevated fasting serum glucose and glycosylated hemoglobin (HbA1c, 12.9%) and normal fasting C-peptide and insulin levels. We performed Roux-en-Y reconstruction after subtotal gastrectomy to treat gastroparesis and improve glycemic control, and the patient showed complete resolution of gastrointestinal symptoms postoperatively. Barium swallow test and gastric emptying time scan performed at follow-up revealed regular progression of barium and normal gastric emptying. Three months postoperatively, his fasting serum glucose level was within normal limits without the administration of insulin or oral antidiabetic drugs with a reduced HbA1c level (6.9%). Long-limb Roux-en-Y reconstruction after subtotal gastrectomy may be useful to treat severe diabetic gastroparesis by improving gastric emptying and glycemic control.

The therapeutic anti-diabetic effect of Nelumbo Folium and a poly herbal formula (NOC) was evaluated in the streptozotocin (STZ 60 mg/kg, I.p.) induced diabetic rats. For this study, test articles were orally administrated once a day from 7 d after STZ-injection for 3 weeks. The fasting blood glucose, body weight, pancreas weight changes, oral glucose tolerance test, hemoglobin Alc (Hb A1c) level changes and the histopathological changes were observed. WNL-treated rat had lower fasting blood glucose levels compared to control group and NOC-treated rat had significantly lower fasting blood glucose levels, compared to control group (p < 0.05). After 21 days of extract treatment, body weight in control was reduced (p < 0.001). WNL and NOC groups were also reduced compared to control group but insignificantly. Pancreas weight of control group was reduced (p < 0.001), but the weight of NOC group were increased (P< 0.05). During the 2 h oral glucose tolerance test (OGTT), WNL group were improved compared to control group (P < 0.05). NOC group were improved compared to control group but insignificantly. WNL and NOC groups had lower Hb Alc level compared to control group. In addition, atrophy of islet and decrease of insulin-producing cells were detected in STZ induced diabetes rats. However, these diabetic changes were decreased in WNL and NOC groups. These results suggest that N. Folium and NOC have favorable effects to inhibit the changes on the fasting blood glucose levels, pancreas weight, glucose tolerance, hemoglobin Alc and the histopathological changes of pancreas in STZ-induced diabetes.

The plasma HGH concentrations were assayed in total 138 cases by the radioimmunoassay. The groups of control, typhoid fever, epidemic hemorrhagic fever, tuberculous meningitis and other febrile diseases were studied, also were the groups of hyperthyroidism, acromegaly and hypopitutarism. Insulin stimulation test was performed in control, typhoid fever and hypopituitarism. In the control group, the plasma HGH concentration in fasting (early morning) was $2.06{\pm}1.183m{\mu}g/ml$ and its upper limit was $4.5m{\mu}g/ml$. No sexual difference was observed. By the insulin stimulation, plasma HGH concentration had rised to the peak level of $24.1{\pm}15.71m{\mu}g/ml$, 60 min. after the intravenous insulin injection, then decreased to the normal level progressively. In typhoid fever, fasting HGH concentrations in febrile state and in defeverence were $2.5{\pm}1.35m{\mu}g/ml\;and\;2.2{\pm}3.32m{\mu}g/ml$ respectively, showing no significant difference with the control group. However, the levels of individual cases ranged widely, conpared with the control group. The response to the insulin stimulation test was similar to the control group. In epidemic hemorrhagic fever the HGH concentrations in oliguric phase, in diuretic phase and in convalescence were $4.2{\pm}3.71m{\mu}g/ml,\;2.2{\pm}1.30m{\mu}g/ml\;and\;3.4{\pm}3.01m{\mu}g/ml$ respectively. No significant differences were observe compared to the control, but they showed wide range of plasma HGH levels. In tuberculous meningitis, the fasting HGH concentration was $2.9{\pm}1.42m{\mu}g/ml$. In the other febrile diseases, the value was $2.5{\pm}2.23m{\mu}g/ml$. In 4 cases of hypopituitarism, the fasting HGH concentration was $2.3{\pm}0.42m{\mu}g/ml$ and ranged normally. However, the response to the insulin stimulation test was not observed. Very high plasma HGH concentrations were observed in acromegalic patients.
