  • 산화적 스트레스는 당뇨병과 관련된 맥관계병변의 전개에 아주 중요한 역할을 한다고 알려져 있다. 따라서 본 실험에서는 streptozotocin(STZ)투여에 의한 당뇨유발쥐를 사용하여 참께함유 항산화성분인 sesamin과 sesamolin의 혈당과 생체내 항산화 방어효소에 미치는 효과에 대하여 알아보고자, 당뇨유발쥐에 0.2% sesamin또는 0.2% sesamolin 함유사료를 3주간 급여하여, 혈당농도, 뇨당농도, 혈청 GOT와 GPT활성, 혈청 및 간조직의 지질과산화물,그리고 GSH함량과 GST활성에 미치는 영향을 조사하였다. STZ투여군의 혈당량은 319.4 $\pm$105.74mg/dL였는데, sesamin급여군은 146.56$\pm$23.99mg/dL, sesamolin급여군은170.74$\pm$105.94mg/dL로 유의하게 감소하였다. 당뇨병쥐의 뇨당농도가 21.16$\pm$13.72 mg/dL였는데, 세사민과 세사몰린 급여시에는 19.52 $\pm$ 8.99 mg/day와 10.93 $\pm$ 7.79 mg/day로 유의하게 감소하였다. STZ투여에 의하여 증가된 GOT와 GPT활성도는 세사민과 세사몰린의 급여에 의하여 GPT활성도만이 유의하게 감소되었다. STZ투여에 의해 증가한 간조직 중의 지질과산화물 생성은 세사민과 세사몰린 급여에 의해 유의하게 감소하였다. STZ투여에 의해 감소된 신장의 GSH함량과 GST활성은 세사민과 세사몰린에 의해 회복되었다. 이상의 결과 세사민과 세사몰린이 신장조직에서 일차적으로 산화된 산화물을 포집하고 GSH를 이용하여 체내의 독성 물질을 전이 분해시키는 작용을 하여 STZ에 의해 유도된 각종 독성을 무독화시켜 신장의 손상을 보호하여 당뇨억제 작용과 함께 항산화 효과를 나타낸 것으로 생각된다.

  • This study was performed to investigate the relationship between reversed circadian blood pressure and risk factors of peripheral vascular disease in non-insulin-dependent diabetes mellitus (NIDDM) subjects. The subjects in this study were 18 NIDDM patients who were hospitalized in a medical unit of an university medical center located in Incheon, Korea, between November, 1998 and March, 1999. Blood pressure was measured with a mercury sphygmomanometer by 2 trained examiners every 2 hours during 24 hours. NIDDM subjects were divided into a dipper group and non-dipper group. Dippers are defined as those who show a mean nighttime blood pressure(BP) drop of more than 10% compared with daytime BP. Non-dippers are defined as those who show a mean nighttime BP drop of less than 10%, or an elevation in BP compared with daytime BP. Daytime BP included values obtained between 6 a.m. and 10 p.m. Night time BP included values obtained between 10 p.m. and 6 a.m. Data was analyzed by SPSS/PC package. Chi-square( $^2$) test was used for the comparison of sex between The dipper group and non-dipper group. Mann-Whitney test was used for comparisons of values of the risk factors of peripheral vascular disease and the frequency of complications of diabetes between the dipper group and non-dipper group. The results are as follows. There were no significant differences in daytime systolic, diastolic, and mean blood pressures between the dipper group and non-dipper group. However, night time systolic, diastolic, and mean blood pressures in the non-dipper group were significantly nigher than those in the dipper group (p=.021). There were no differences in sex, age, body, weight, duration of diabetes, serum lipid levels, BUN and HbA1c between the two groups. On the contrary, 87.5% of non-dipper group subjects showed having hypertension, 30% of dipper group subjects showed having hypertension and this difference was statistically significant (p=.018). All of the non-dipper group subjects (N=8) showed having at least one diabetic complication. However, 40% of the dipper group subjects (N=10) showed having no diabetic complication at all and this difference was also statistically significant (p=.049). There were no significant differences in frequency of nephropathy, neuropathy and retinopathy between the dipper group and non-dipper group.

  • 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.

  • Bambusae caulis in Liquamen is one of the important herbal medicine produced by heating bamboo indirectly and is used for treatment of stroke, hypertension, and diabetes etc. Recently the mechanism of clinical effects on Bambusae caulis in Liquamen has been studied. This experiment was conducted to confirm the clinical effects of Bambusae caulis in Liquamen on type 1 diabetes and its related mechanism. We divided C57BL/6 mice into 3 groups and induced them to be type 1 diabetes by injection of streptozocin into peritoneum. The dosage of each group was 150 mg/kg once only, 140 mg/kg once only and 40 mg/kg for 5 days respectively. The two groups injected streptozocin for once took orally Bambusae caulis in Liquamen after the induction of diabetes, and the other one group was given Bambusae caulis in Liquamen during the diabetes inducing period. As the result, the two diabetes-induced groups showed blood glucose decreasing effect by Bambusae caulis in Liquamen on an average, but they didn't show the signiftcant differences statistically. But Bambusae caulis in Liquamen showed the anti-diabetic effect suppressing blood sugar rising trend during the diabetes inducing peried (P<0.05). The anti-oxidative effect of Bambusae caulis in Liquamen was measured with the hypoxanthine/xanthine oxidase (HX/XOD) system. The quantity of ROS was measured using DCFDA reagent indirectly. As the result, $10\%$ solution of Bambusae caulis in Liquamen showed anti-oxidative effect by scavenging $93.4\%$ superoxide as compared with control group. It is suspected that the anti-oxidative effect of Bambusae caulis in Liquamen suppressed the increase of blood glucose in the diabetes-inducing group. These results could be useful data to understand the effect of Bambusae caulis in Liquamen on type 1 diabetes and type 1 diabetes developing because ROS were closely connected with the induction and complications of diabetes.

  • Purpose: With increasing life expectancy, the presence of comorbidities has become a major concern in elderly patients who require surgery. However, little is known about the impact of different comorbidities on the outcomes of laparoscopic total gastrectomy (LTG). In this study, we investigated the impact of comorbidities on postoperative complications in patients undergoing LTG for gastric carcinoma. Materials and Methods: We retrospectively reviewed the cases of 303 consecutive patients who underwent LTG for gastric carcinoma between 2005 and 2016. The associations between each comorbidity and postoperative complications were assessed using univariate and multivariate analyses. Results: A total of 189 patients (62.4%) had one or more comorbidities. Hypertension was the most common comorbidity (37.0%), followed by diabetes mellitus (17.8%), chronic viral hepatitis (2.6%), liver cirrhosis (2.6%), and pulmonary (27.1%), ischemic heart (3.3%), and cerebrovascular diseases (2.3%). The overall postoperative morbidity and mortality rates were 20.1% and 1.0%, respectively. Patients with pulmonary disease significantly showed higher complication rates than those without comorbidities (32.9% vs. 14.9%, respectively, P=0.003); patient with other comorbidities showed no significant difference in the incidence of LTG-related complications. During univariate and multivariate analyses, pulmonary disease was found to be an independent predictive factor for postoperative complications (odds ratio, 2.14; 95% confidence interval, 1.03-4.64), along with old age and intraoperative bleeding. Conclusions: Among the various comorbidities investigated, patients with pulmonary disease had a significantly higher risk of postoperative complications after LTG. Proper perioperative care for optimizing pulmonary function may be required for patients with pulmonary disease.

  • This study was conducted to determine the incidence of wound complications after laparotomy for endometrial cancer and significant predictors of risks. Medical records of patients with endometrial cancer undergoing laparotomy for surgical staging at Srinagarind Hospital, Khon Kaen University between January 2007 and December 2013 were reviewed. Intravenous antibiotic prophylaxis was routinely given 30 minutes before surgery. The primary endpoint was wound complications (including seroma, hematoma, separation, or infection) requiring additional medical and/or surgical management within 4 weeks of laparotomy. During the study period, 357 patients with complete medical records were reviewed. The mean age was 56.9 years. Wound complications were observed in 28 patients (7.84%, 95% CI, 5.27% to 11.14%). Body mass index (BMI) ${\geq}30kg/m^2$, diabetes mellitus (DM), and prior abdominal surgery were observed as significant independent factors predicting an increased risk of wound complications with adjusted odds ratios (95% CIs) of 2.96 (1.23-7.16), 2.43 (1.06-5.54), and 3.05 (1.03-8.98), respectively. In conclusion, the incidence of wound complications after laparotomy for endometrial cancer was 7.8%. Significant independent predictors of risk included BMI, DM and prior abdominal surgery.

  • Background: There is inadequate information on the validation of diabetic microvascular complications in the Korean National Health Insurance Service data set. We aimed to validate the diagnostic algorithms regarding the nephropathy, neuropathy, and retinopathy of diabetes. Methods: From various secondary and tertiary medical centers, we selected 6,493 patients aged ≥ 40 years who were diagnosed with diabetic microvascular complications more than once based on codes in the 10th version of the International Classification of Diseases (ICD-10). During 2019 and 2020, we randomly selected the diagnoses of 200 patients, 100 from each of two hospitals. The positive predictive value (PPV), negative predictive value, error rate, sensitivity, and specificity were determined for each diabetic microvascular complication according to the ICD-10 codes, laboratory findings, diagnostic studies, and treatment procedure codes. Results: Among the 200 patients who visited the hospital more than once and had the diagnostic codes of diabetic microvascular complications, 142, 110, and 154 patients were confirmed to have the gold standard of diabetic nephropathy (PPV, 71.0%), diabetic neuropathy (PPV, 55.0%), and diabetic retinopathy (PPV, 77.0%), respectively. The PPV and specificity of diabetic nephropathy (PPV, 71.0-81.4%; specificity, 10.3-53.4%), diabetic neuropathy (PPV, 55.0-81.3%; specificity, 66.7-76.7%) and diabetic retinopathy (PPV, 77.0-96.6%; specificity, 2.2-89.1%) increased after combining them with the laboratory findings, diagnostic studies, and treatment procedures codes. These change trends were observed similarly for both hospitals. Conclusions: Defining diabetic microvascular complications using ICD-10 codes and their related examination codes may be a feasible method for studying diabetic complications.

  • Dysfunction of endothelial cells is considered a major cause of vascular complications in diabetes. In the present study, we investigated the protective effect of Padina arborescens extract against high glucose-induced oxidative damage in human umbilical vein endothelial cells (HUVECs). High-concentration of glucose (30 mM) treatment induced cytotoxicity whereas Padina arborescens extract protected the cells from high glucose-induced damage and significantly restored cell viability. In addition, lipid peroxidation, intracellular reactive oxygen species (ROS), and nitric oxide (NO) levels induced by high glucose treatment were effectively inhibited by treatment of Padina arborescens extract in a dose-dependent manner. High glucose treatment also induced the overexpressions of inducible nitric oxide synthase (iNOS), cyclooxygenase- 2 (COX-2) and NF-${\kappa}B$ proteins in HUVECs, but Padina arborescens extract treatment reduced the over-expressions of these proteins. These findings indicate the potential benefits of Padina arborescens extract as a valuable source in reducing the oxidative damage induced by high glucose.

  • Of 16 million diabetic patients in the USA, 2.4 millions have experienced diabetic foot ulcer and 67,000 have amputations every year. For treatment of diabetic foot ulcer, Americans spend more than $1 billion each year, including $36,000 per patient for complete treatment and $60,000 for each amputation. Neuropathy and ischemia, two common complications of diabetes mellitus, are the primary underlying risk factors for development of diabetic foot ulcers. Ischemic ulcers develop as a result of low perfusion pressure in the foot with inadequate blood supply, whereas neuropathic ulcers develop from loss of protective sensation. In addition, diabetes also increases the risk of infection by impairing the body's ability to eliminate bacteria. From these circumstances, results are chronic wounds with impaired healing ability.
