  • Since conflicting results have been reported on non-specific immune response in type 1 diabetes, this study evaluates polymorphonuclear neutrophil (PMN) functions in the infection free Long Evan diabetic rats (type 1) by using tests that include: polarization assay, phagocytosis of baker's yeasts (Saccharomyces cerevisiae) and nitroblue tetrazolium (NBT) dye reduction. Polarization assay showed that neutrophils from diabetic rats were significantly activated at the basal level compared to those from the controls (p < 0.001). After PMN activation with N-formyl-methionyl-leucyl-phenylalanine (FMLP), control neutrophils were found to be more polarized than those of the diabetic neutrophils and the highest proportions of polarization were found to be 67% and 57% at $10^{-7}\;M$ FMLP, respectively. In the resting state, neutrophils from the diabetic rats reduced significantly more NBT dye than that of the controls (p < 0.001). The percentages of phagocytosis of opsonized yeast cells by the neutrophils from control and diabetic rats were 87% and 61%, respectively and the difference was statistically significant (p < 0.001). Evaluation of the phagocytic efficiency of PMNs revealed that control neutrophils could phagocytose $381{\pm}17$ whereas those from the diabetic rats phagocytosed $282{\pm}16$ yeast cells, and the efficiency of phagocytosis varied significantly (p < 0.001). Further, both the percentages of phagocytosis and the efficiency of phagocytosis by the diabetic neutrophils were inversely related with the levels of their corresponding plasma glucose (p = 0.02; r = -0.498 and p < 0.05; r = -0.43, respectively), which indicated that increased plasma glucose reduced the phagocytic ability of neutrophils. Such relationship was not observed with the control neutrophils. These data clearly indicate that PMN functions are altered in the streptozotocin (STZ) - induced diabetic rats, and hyperglycemia may be the cause for the impairment of their functions leading to many infectious episodes.

  • Purpose: To investigate the characteristics of the patients and therapeutic shoes for diabetic patients. Materials and Methods: Forty two diabetic patients who had their own therapeutic shoes which were prescribed somewhere else were studied from March 2003 to December 2003. There were 27 males and 15 females, and the mean age was 62.1 years (range, 49-72 years). Duration of diabetes was average 14 years (range, $6{\sim}30$ years), all had type 2 diabetes. Sensation was examined with 5.07 nylon monofilament. The route of purchasing the shoes, compliance to the prescribed shoes were investigated by interview. The shape of shoe, stiffness of upper, conformity of insole to the shape of the foot were recorded. In-shoe plantar pressure was measured in 15 patients. Results: Eighteen patients were insensate to the monofilament. Seven patients did not wear the therapeutic shoes, and only 18 of 35 patients were wearing the therapeutic shoes more than 6 hours a day. The shoes of 17 patients were prescribed by medical doctor and the rest were purchased by the recommendation of acquaintances or advertisement. Ulcer recurred in four of five patients to whom the shoe was prescribed by medical doctor and the cause of three recurrences were evident by just observing the foot and shoe. The therapeutic shoes were made from 11 different makers. Eight shoes were adequate for diabetic patients with respect to the material, shape of insole, type of shoe. In-shoe plantar pressure was examined in 15 patients and was less than 300 kPa in all patients. Conclusion: The therapeutic shoes for the diabetic patients need to be prescribed by medical doctor for selective patients with neuropathy or previous history of ulcer and follow-up examination is important to monitor the compliance of the patients and adequacy of the shoes.

  • 뇌졸중은 사망발생 및 장애를 일으키는 주요 원인 질환이며, 당뇨병은 뇌졸중의 주요 위험인자이다. 당뇨병 환자가운데 뇌졸중을 동반한 환자에서 적정 혈압 관리의 중요성을 알아보고자 한다. 제6기 국민건강영양조사 자료를 바탕으로 18세 이상 80세 미만자 총 16,389명을 대상으로 회귀분석을 통하여 당뇨병 유병기간에 따른 혈압조절을 통한 뇌졸중의 위험도를 산정하였다. 당뇨병 유무에 따른 뇌졸중의 유병률은 당뇨병 환자 군에서 높았고, 당뇨병의 유병기간이 길어질수록 고혈압과 뇌졸중의 위험도는 상승하였으며, 당뇨병과 고혈압에 대한 치료 비율은 높았다. 고혈압군에 비해 적정 혈압 유지군(<140/<90 mmHg)에서 뇌졸중 위험비(HR)는 0.57 낮았다. 당뇨병과 고혈압에 대한 치료가 동반됨에도 불구하고 고혈압의 빈도는 상승하였고, 당뇨병 유병기간 5년 이후 뇌졸중의 유병률이 상승함에 따라 이 시기의 효과적인 혈압관리가 더욱 중요하다. 당뇨병 환자에서 지속적으로 적정 혈압으로 관리함으로써 뇌졸중 위험도를 낮추는 것이 중요하다.

  • The overexpression of Phosphoprotein Enriched in Astrocytes (PEA15) gene is commonly found in human diabetic patients. The overexpression of this gene in skeletal muscle and fat tissues have been reported to cause insulin resistance, thereby impairing insulin stimulated glucose uptake. We introduced a gene of mouse PEA15 (mPEA15) and enhanced green fluorescent protein (EGFP) into fertilized one cell pig zygotes using microinjection, and produced a piglet that showed overexpression of mPEA15 in the muscle tissues and expression of EGFP in the ear tissues and hooves. RT-PCR RFLP, southern blot and FISH analysis showed that the tissues carried the transgene. Real-time RT-PCR and western blots demonstrated that PEA15 gene was overexpressed in the various tissues and muscle tissues, respectively. These fads suggest that expression vector system is normally expressed in the transgenic (TG) pigs. To use as animal diseases model for type 2 diabetes, further study is necessary to confirm whether diabetes occur in these TG pigs, especially insulin resistance.

  • Background: Accumulating evidence suggests that metformin possesses anticarcinogenic properties, and its use is associated with favorable outcomes in several cancers. However, it remains unclear whether metformin influences prognosis in prostate cancer (PCa) with concurrent type 2 diabetes (T2D). Materials and Methods: We searched PubMed, EMBASE, and the Cochrane Library from database inception to April 16, 2014 without language restrictions to identify studies investigating the effect of metformin treatment on outcomes of PCa with concurrent T2D. We conducted a meta-analysis to quantify the risk of recurrence, progression, cancer-specific mortality, and all-cause mortality. Summary relative risks (RRs) with corresponding 95% confidence intervals (CIs) were calculated. Publication bias was assessed by Begg's rank correlation test. Results: A total of eight studies fulfilled the eligibility criteria. We found that diabetic PCa patients who did not use metformin were at increased risk of cancer recurrence (RR, 1.20; 95%CI, 1.00-1.44), compared with those who used metformin. A similar trend was observed for other outcomes, but their relationships did not reach statistical significance. Funnel plot asymmetry was not observed among studies reporting recurrence (p=0.086). Conclusions: Our results suggest that metformin may improve outcomes in PCa patients with concurrent T2D. Well-designed large studies and collaborative basic research are warranted.

  • Purpose: Diabetes Mellitus (DM) is a leading cause of death with a prevalence rate of 12.4% in South Korea. Self-management is crucial for patients with DM, because many studies have reported that self-management intervention based on the Health Belief Model (HBM) is effective. The purpose of this study was to investigate the current state of HBM based intervention studies and the components and effects of the theories used in the study for diabetes patients. Methods: A systematic review was conducted using the Pubmed, Cochrane Library and Embase databases from January 2009 to May 2019. We reviewed characteristics of intervention based on the HBM in randomized controlled clinical trials (RCTs), quasi-experimental study intervention. Results: Eight studies published in English between 2009 and 2019 were included in this review. The key components of the health behavior promotion program applied to the DM patients were perceived susceptibility, perceived severity, perceived benefits, perceived barriers and self-efficacy. The intervention based on these components has reported to significantly increase the health behavior change, likelihood of taking health action and improve physiological indicators (HbA1c, and fasting blood sugar etc.). Conclusion: This study highlighted the importance of intervention programs based on the HBM for DM patients.

  • Diabetic nephropathy (DN) is a common complication and the leading cause of end-stage renal disease (ESRD) in diabetic patients. The occurrence of non-diabetic renal disease (NDRD) in diabetic patients has been increasingly recognized in recent years. Generally, renal injuries in DN are deemed difficult to reverse, whereas some NDRDs are often treatable and even remittable. Thus, the diagnosis of NDRD in patients with diabetes mellitus (DM) via a kidney biopsy would be significant for its prognosis and therapeutic strategy. According to recent studies, the most common NDRD is IgA nephropathy in type 2 diabetic patients, and some cases of minimal change disease and membranous glomerulonephritis have been reported in Korea. However, membranoproliferative glomerulonephritis (MPGN) is an uncommon condition in diabetic patients. To our knowledge, there has been no case yet of MPGN, except in a child with type 1 DM. We present an unusual case of a 27-year-old woman who had type 2 DM with MPGN, as confirmed via a kidney biopsy.

  • A dietary treatment of Chinese medicine for diabetes mellitus was extensively studied and compared with that of western medicine. The main results are as follows: Chinese medicine is based on the following empirical dietetics. First, likeness helps likeness. When an internal organ of mankind is not functioning properly, the food or drug from the same organ of an animal will be helpful to cure it. Second, take good foods for health properly and never take any foods against body. Third, building up one's body by taking tonics is not quite the same as building up one's body through proper eating. On the other hand, western medicine is based on the experimental and scientific methods which are modernized in accordance with the development of science and technology. It emphasizes upon finding the cause of a disease. Then this disease can be cured by doing a necessary medical treatment which sometime uses a surgical operation or chemical and radiological method or both. Although there are many ways in treating a diabetic in Western Medicine, here the diabetics is supposed to be the best. The same is true for Chinese Medicine. Therefore one can easily conclude that the dietetics is the most important and effective of all irrespective of Western and Chinese Medicine as far as diabetesis concerned. In Western Medicine, a diabetic is recommened to have the minimum calories necessary for life and not to have goods containing glucide beyond a certain quantity, while in Chinese medicine a diabetic is not allowed to have foods containing more than 10% of glucide. These two facts suggest that a diabetic should pay careful attention to foods containing lots of glucide. Finally a systematic cooperation between western and Chinese medicine will cure not only diabetes but also other disease more effectively than a traditionally unilateral method.

  • A patients with quadriplegia and a history of pancreatectomy was administered Socheongryong-tang to reduce sputum. The patient's sputum decreased, but a sudden increase in blood sugar was observed. Ephedra is known to stimulate the sympathetic nerves to increase the blood pressure and blood sugar, but in healthy people, changes in blood sugar are not significant due to corrections by hormone regulation. However, this case suggests that ephedra can cause significant blood sugar increases in patients who undergo pancreatectomy or who have diabetes mellitus. Even though ephedra is highlighted for its usefulness in sputum reduction and in weight control, it should be carefully prescribed to patients with diabetes.

  • Background The impact of diabetes on complication rates following free flap (FF), pedicled flap (PF), and amputation (AMP) procedures on the lower extremity (LE) is examined. Methods Patients who underwent LE PF, FF, and AMP procedures were identified from the 2010 to 2020 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP®) database using Current Procedural Terminology and International Classification of Diseases-9/10 codes, excluding cases for non-LE pathologies. The cohort was divided into diabetics and nondiabetics. Univariate and adjusted multivariable logistic regression analyses were performed. Results Among 38,998 patients undergoing LE procedures, 58% were diabetic. Among diabetics, 95% underwent AMP, 5% underwent PF, and <1% underwent FF. Across all procedure types, noninsulin-dependent (NIDDM) and insulin-dependent diabetes mellitus (IDDM) were associated with significantly greater all-cause complication rates compared with absence of diabetes, and IDDM was generally higher risk than NIDDM. Among diabetics, complication rates were not significantly different across procedure types (IDDM: p = 0.5969; NIDDM: p = 0.1902). On adjusted subgroup analysis by diabetic status, flap procedures were not associated with higher odds of complications compared with amputation for IDDM and NIDDM patients. Length of stay > 30 days was statistically associated with IDDM, particularly those undergoing FF (AMP: 5%, PF: 7%, FF: 14%, p = 0.0004). Conclusion Our study highlights the importance of preoperative diabetic optimization prior to LE procedures. For diabetic patients, there were few significant differences in complication rates across procedure type, suggesting that diabetic patients are not at higher risk of complications when attempting limb salvage instead of amputation.
