Purpose : Iron accumulation interferes with hepatic insulin extraction and affects insulin synthesis and secretion. The purpose of this study is to investigate the correlation between serum ferritin and type 2 diabetes mellitus. Methods : We compared the serum ferritin level among 18 patients in an impaired glucose tolerance (IGT) group, 36 in a type 1 diabetes group, eight in a type 2 diabetes group and 29 in a healthy control group. The correlation between serum ferritin levels and sex, body mass indices(BMI), blood pressure(BP), serum fasting sugar level and serum fasting insulin level were also analyzed. Results : The mean log ferritin were $1.33{\pm}0.32$(healthy control group), $1.63{\pm}0.19$(IGT group) and $1.90{\pm}0.30$(type 2 diabetes group). In the IGT group, log ferritin was higher than in the healthy control group(P=0.001). The log ferritin of the type 2 diabetes group was higher than that of the healthy control group(P=0.001). Comparing log ferritin to other factors, log ferritin had a significant positive correlation with body mass indices(P<0.001), systolic blood pressure(P=0.001), and fasting glucose(P=0.001), fasting insulin(P=0.002). Conclusion : Compared to the normal healthy group, serum ferritin concentrations were significantly higher in the IGT group and the type 2 diabetes group. The elevation of serum ferritin concentration may be a risk factor of type 2 diabetes mellitus.

흔히 뱃살이 나오는 것으로 표현되는 복부비만은 배에 과도한 지방이 축적된 상태로, 한국인의 허리둘레 기준으로는 남자 35.4인치(90cm), 여자 33.5인치(85cm) 이상인 경우에 해당한다. 지금까지 복부비만은 대사증후군의 일환으로서 당뇨병 발생 위험이나 심혈관계 질환의 위험을 높이는 것으로 알려져 왔으나 최근의 연구 결과에 따르면 허리둘레가 독립적으로 제2형 당뇨병 발병 위험과 밀접하게 연관된 것으로 나타났다.

Objectives : The aims of this study were to know the frequency and the nature of cognitive dysfunction in type 2 diabetics, and to reveal influencing variables on it. Methods : From eighty type 2 diabetics (42 males and 38 females), demographic and clinical data were obtained by structured interviews. Cognitive functions were measured using the MMSE-K (Korean Version of the Mini-Mental State Examination) and the Korean Version of the Montreal Cognitive Assessment (MoCA-K) tests. Severity of depression was evaluated by the Korean Version of the Hamilton Depression Rating Scale (K-HDRS). Results : 1) Among eighty type 2 diabetics, 13.75% were below 24 on the MMSE-K, while 38.8% were below 22 on the MoCA-K. 2) The total scores and subtest scores of the MoCA-K including visuospatial/ executive, attention, language, delayed recall and orientation were significantly lower in type 2 diabetics with cognitive dysfunction (N=31) than those without cognitive dysfunction (N=49) (p<0.001, respectively). 3) There were significant difference between type 2 diabetics with and those without cognitive dysfunction in age, education, economic status, body mass index, duration of diabetes, total scores of the K-HDRS, the MMSE-K and the MoCA-K (p<0.05, respectively). 4) The total scores of the MoCA-K had significant correlation with age, education, body mass index, family history of diabetes, duration of diabetes, total scores of the K-HDRS (p<0.05, respectively). 5) The risks of cognitive dysfunction in type 2 diabetics were significantly influenced by sex, education, fasting plasma glucose and depression. Conclusions : The cognitive dysfunction in type 2 diabetics seemed to be related to multiple factors. Therefore, more comprehensive biopsychosocial approaches needed for diagnosis and management of type 2 diabetes.

The purpose of this study was to explore the cultural perspectives and experiences relating to insulin therapy among the diabetes. The authors conducted four semi-structured focus groups and individual interviews with 19 adults with type 1 and 2 diabetes, focusing on the personal experiences and thoughts regarding insulin therapy. Patients' perspectives and experiences relating to taking insulin formed three categories of themes: preoccupations about insulin, barriers to taking insulin, and benefits to taking insulin. The theme for preoccupations about insulin was "vague fear," while the theme of barriers to taking insulin were "worrisome insulin-related issues", "ambivalent feelings (trust/mistrust) about healthcare providers," "dependent life," "feeling about supporters(family, friends, and religion)," "inconvenience," "regret about the past," and "embarrassment." The theme of benefits to taking insulin were "recognition" and "physical recovery and confidence in regulating blood glucose". Based on this study, patients' feelings about their insulin should be respected by healthcare providers.

The insulin-like growth factors(IGFs) are bound to several binding proteins(IGFBPs) that appear to regulate IGF transport, receptor binding, and its action. The concentration of these peptides are altered by catabolic conditions. To determine IGF-I and IGFBP levels in noninsulin-dependent diabetes mellitus (NIDDM), sera was obtained from 5 patients and 7 controls. Serum levels of IGF-I in NIDDM were lower than those in either of the controls. By western immunoblot analysis, especially IGFBP-1 levels are increased, whereas IGFBP-3 levels decreased and their fragments was increased in NIDDM serum. IGFBP-3 proteolytic activity in NIDDM sera was inhibited by phenylmethylsulfonylfluoride (PMSF), aprotinin, and ethylenediaminetetraacetic acid(EDTA). This pattern of inhibition was consistent with a metal-dependent serine protease. By gelatin zymography, these proteolytic enzymes were identified as the size of 97 and 69 kDa. IGFBP-1, which is primarily insulin regulated, was increased in NIDDM and may modulate circulating IGF-I levels by regulating capillary passage of IGF-I. IGFBP-3 proteolysis markedly reduces its affinity for the IGFs, particularly for IGF-I. This accelerates their kinetics of dissociation, thereby increasing the proportions of IGF-I in free form and its availability to the cells.

The purpose of this study was to quantify and compare the level of MMP-1 in the healthy or inflamed gingival tissue of patients with or without type 2 diabetic mellitus. We investigated whether mean amount of MMP-1 was changed by chronic periodontitis and type 2 DM. Gingival tissue samples were obtained during periodontal surgery or tooth extraction. According to the patient's systemic condition & clinical criteria of gingiva, each gingival sample was divided into the three group. Group 1(n=8) was clinically healthy gingiva without bleeding and no evidence of bone resorption or periodontal pockets, obtained from systemically healthy 8 patients. Group 2(n=8) was inflamed gingiva from patients with chronic periodontitis. Group 3(n=8) was inflamed gingiva from patients with chronic periodontitis and type 2 diabetes. Tissue samples were prepared and analyzed by Western blotting. The quantitative analysis of MMP-1 was performed using a densitometer and statistically analyzed by ANOVA. MMP-1 was expressed in all samples and an increased MMP-1 level was observed in group 2 compared to group 1 and decreased MMP-1 level was found group 3 compared to group 2, but the differences among 3 groups were not statistically significant. In conclusion, this study demonstrated that MMP-1 levels of inflamed gingiva of systemically healthy patient(group 2) were higher than normal gingiva of systemically health patients and although the severity of gingival inflammation in group 2 and 3 were similar, MMP-1 expression was decreased in diabetic patients than systemically healthy periodontal patients.
