Purpose: To observe the histologic changes and clusterin expression in the acinar cells of the submandibular gland in streptozotocin-induced diabetic rat following irradiation. Materials and Methods: Mature Sprague-Dawley rats were divided into three groups: control, diabetic, and diabetic-irradiated groups. Diabetes mellitus was induced in the Sprague-Dawley rats by injecting streptozotocin, while the control rats were injected with citrate buffer only. After 5 days, rats in diabetic-irradiated group were irradiated with single absorbed dose of 10 Gy to the head and neck region. The rats were killed at 1, 3, 7, 14,21, and 28 days after irradiation. The specimen including the submandibular gland were sectioned and observed using histologic and immunohistochemical methods. Results : Morphologic change of acinar cells was remarkable in the diabetic group, but was not observed in the diabetic-irradiated group. Necrotic tissues were observed in the diabetic-irradiated group. Coloring of toluidine blue stain was most increased at 14 days in the diabetic group, however there were no significant change throughout the period of the experiment in the diabetic-irradiated group. Expression of clusterin was most significant at 14 days in the diabetic group, but gradually decreased with time after 7 days in the diabetic-irradiated group. Degeneration of clusterin was observed in the diabetic-irradiated group. Conclusion : This experiment suggests that the acinar cells of submandibular gland in rats are physiologically apoptosed by the induction of diabetes, but that the apoptosis is inhibited and the acinar cells necrotized after irradiation.

A novel gene Jpk, originally isolated as a trans-acting factor associating with the position-specific regulatory element of murine Hox gene has been reported to be expressed differentially in the liver of diabetic animals. Therefore, in an attempt to develop a possible diagnostic marker and/or new therapeutic agent for the Diabetes Mellitus, we analysed the expression pattern of Jpk among organs of normal and diabetic Sprague-Dawley (SD) rats. Total RNAs were isolated from each organs (brain, lung, heart, liver, spleen, kidney, muscle, blood, and testis) of diabetic and normal rats in both normal feeding and after fasting condition. And then RT (reverse transcription) PCR has been performed using Jpk­specific primers. The Jpk gene turned out to be expressed in all organs tested, with some different expression profiles among normal and diabetes, though. Upon fasting, Jpk expressions were reduced in all organs tested except kidney, muscle and brain of normal rat. Whereas in diabetes, Jpk expressions were increased in all organs except heart, muscle and testis when fasted. Compared to the normal rat, the Jpk expression level in blood was remarkably upregulated (about 15-30times) in diabetic rat whether in normal feeding or fasting conditon, suggesting that the Jpk could be a candidate gene for the possible blood diagnostic marker for the Diabetes Mellitus.

Objectives : The present study was designed to investigate the anti-diabetic effects of Mori Folium (Morus alba L. of Moraceae) extract (MFE) on high fat diet (HFD) and streptozotocin (STZ)-induced type II diabetes mellitus in mice. Methods : The mice (C57BL/6J) were fed HFD for 8 weeks and then was induced with a single injection of STZ (75 mg/kg). The diabetic mice were divided into four groups [(STD, HFD, HFD + MFE and HFD + quercetin (QUR)] and administered with MFE or OUR for 4 weeks. Fasting blood glucose, lipid profile (triglycerides and cholesterol etc.), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), insulin and leptin were measured every 2 weeks. Results : Body weight gain was lower in the MFE and QUR groups than HFD group. The fasting blood glucose was lower in the MFE and QUR groups. Oral glucose and insulin tolerance were decreased in the MFE and QUR groups. The levels of serum total cholesterol, triglycerides, and LDL cholesterol were reduced in the MFE and QUR groups. The HDL cholesterol was much higher in the MFE and QUR groups than HFD group. The levels of GOT, GPT and atherogenic index were decreased in the MFE and QUR groups. The serum insulin and leptin concentrations were reduced in the MFE and QUR groups. Conclusions : These results showed that MFE could decrease blood glucose level and lead to an amelioration in dyslipidemia states on HFD/STZ-induced type II diabetes mellitus in mice.

다시마의 열수출물이 당뇨병의 치료에 효과가 있는지를 알아보기 위하여 alloxan으로 처리하여 실험적으로 당뇨병을 유발한 후 glucose의 초기 인산화에 관여하는 glu-cokinase와 hexokinase의 활성을 살펴본 결과 다음과 같은 결론을 얻었다. 1. Alloxan 주사에 의해 체중과 공복시의 glucose 및 insulin 분비가 증가되었으나, 다시마 투여에 의해 공복시의 insulin 분비가 유의성있게 감소하였으며 체중과 공복시의 glucose의 유의성은 없었으나 대조군에 비하여 감소하였다. 2. Alloxan 주사에 의해 혈청중 glucosecl가 정상군에 비하여 현저하게 증가되었으나 다시마 투여에 의해 현저히 감소되었다. Insulin 치의 상승과 분비 지연도 다시마 투여군에서는 정상군과 유사한 경향을 보였다. 3. Glucokinase와 hexokinase의 활성은 alloxan 주사에 의해 현저히 감소되었으나, 다시마 투여에 의해 유의성있게 상승되었다. 이상의 결과로 다시마는 alloxan으로 유발된 당뇨병에서 glcuose 인산화 glucokinase와 hexokinase의 활성을 증가시키는 것으로 나타나 당뇨병의 치료에 효과가 있는 것으로 여겨진다.

This study was carried out to examine a part of the mechanism for the etiology of diabetic complications. Thirty normal and forty streptozotocin(STZ)-induced diabetic rats were used as the animal models. The animals were sacrificed at the time points of 3 days, 1,2,4 and 6 weeks after STZ-injection and a time course changes in the concentrations of thiobarbituric acid-reactive substances(TBARS) in blood, urine, and tissues, along with the levels of conjugated dienes in tissues were measured as indices of in vivo lipid peroxidation. The activities of antioxidant enzymes, catalase, superoxide dismutase, glutathione peroxidase and the levels of blood retinol and alpha-tocopherol were also measured. The diabetic rats maintained a slightly higher plasma TBARS level throughout the experiment. The urinary TBARS level was significantly higher in diabetic group and gradually increased with time. Concentrations of TBARS in liver, heart, and kidney tissues from diabetic animals were higher than those from the normal group. An increase of conjugated dienes was also observed in the all tissues examined. The kidney tissue of diabetic animals revealed more significant lipid peroxidation state than any other organ tissues. The activities of hepatic antioxidant enzymes such as catalase, superoxide dismutase, glutathione peroxidase were higher in diabetic animals compared to the control ones and increased with the duration of diabetes mellitus. The plasma levels of vitamin A and E were loser in diabetic animals than in normal controls throughout the experimental period. The level of vitamin E in diabetic animals was significantly decreased with the duration of the disease. The results of this study suggest that an effective regimen to suppress the adverse changes in lipid peroxidation and antioxidant defense system is required from the early stage of the disease to prevent the development of diabetic complications.

A miniature schnauzer (8 years old, male castrated), diagnosed as diabetes mellitus 6 months ahead, were referred to the Veterinary Medical Teaching Hospital of our University with hindlimb stiffness, facial rubbing and tetany. Serum chemistry showed severe hypocalcemia, hypomagnesemia, and measured iPTH (intact pharathyroid hormone) concentration was low (< 3.0 pmol/L). Consistent rate injection of calcium gluconate (282 mg/kg over 30 min) resulted in prompt relief of the tetany. Then typical treatment for hypoparathyroidism (calcium gluconate and dihydrotachysterol per os) with magnesium administration could control the neuromuscular signs. Diabetes mellitus is being controlled by insulin therapy and prescription diet. Hypomagnesemia in diabetic dog may be induced hypoparathyrodism.

Objective : The present study was carried out to investigate the preventive effect of Sophorae Flos on streptozotocin - induced Diabetes mellitus. Method : Sophorae Flos was given to rats with oral administration. The experimental animals were divided into 3groups : normal group of rats, control group of Streptozotocin-induced diabetic rats, sample group with Sophorae Flos . The effect of Sophorae Flos on Streptozotocin-induced diabetes was observed by measuring the survival rate of rats, weight of rats, FER, blood glucose, each organ weight of rat, total cholesterol, HDL, GOT, GPT & creatinine. Result : Streptozotocin caused hyperglycemia and hypoinsulinemia by a selectively destroying pancreatic ${\beta}-cell$. Sophorae Flos treatment don't protected them from hyperglycemia and hypoinsulinemia. Organ weight liver, kidney, heart & spleen shows no significant changes. Sophorae Flos significantly don't recoverd the increase of several biochemical parameters such as blood glucose, total cholesterol, HDL, GOT, GPT, antioxidant & creatinine is vice versa. Conclusion : Sophorae Flos extract group did not show significant decrease than Streptozotocin control group.

Purpose: To investigate the histopathological changes in the temporomandibular joint in streptozotocin-induced diabetic rat following irradiation. Materials and Methods : Sprague-Dawley rats weighing about 250 gm were divided into three groups: control, diabetic, and diabetic-irradiated groups. Diabetes mellitus was induced in the rats by injecting streptozotocin. Rats in the control group were injected with citrate buffer only. After 5 days, the head and neck region of the rats in diabetic-irradiated group were irradiated with single absorbed dose of 10 Gy. The rats were killed at 1, 3, 7, 14, 21, and 28 days after irradiation. The specimen including the temporomandibular joint were sectioned and observed using a histopathological method. Results : In the diabetic group, severe bone resorption in the mandibular condyle was observed throughout the period of experiment. Necrosis of bone marrow and trabeculae was observed at 28 days after diabetic state. Atrophy and fibrosis in the retrodisca] tissue was gradually progressed during the time of the experiment. In the diabetic-irradiated group, severe bone resorption in the mandibular condyle was observed during the early experimental phases, but regeneration of bone marrow was initiated at ]4 days after diabetic state and irradiation. A]so, calcification of abnormal trabeculae was observed at 28 days after diabetic state and irradiation. The retrodisca] tissue was degenerated in the early experimental phases, but it had been gradually regenerated during the experimental time. Conclusion: This experiment suggests that bone resorption and degeneration in the mandibular condyle are caused by the induction of diabetes, and abnormal bone formation is induced after irradiation in diabetic state.

Purpose: The purpose of this study was to identify the factors and the relative risk associated with admission of patients with diabetes mellitus (DM). Methods: The sample included one hundred twenty-eight patients with type II DM. Seventy-seven patients who were admitted within six months of a hospitalization to one hospital from the first of February to the 31st of August 2014, were compared with fifty-one patients who regularly attended an outpatient clinic and had no hospitalizations. Results: Hospitalization probabilities among patients who had only diet and exercise or took oral diabetic medication were 0.03 (p=.004) and 0.21 (p=.007) times independently lower than the ones with insulin injection. The risks for hospitalization increases 6.33 times if there is absence of a spouse (p=.027) whereas the presence of a spouse seems to make hospitalization less likely. The risk among the ones having diabetic complications was 5.15 times higher than ones having no recognition of the complications (p=.040). For every one point increase in self-efficacy and every 1 mg/dL increase in high density lipoprotein (HDL) cholesterol, there was a 0.84 (p=.005) and a 0.96 (p=.036) decrease in hospitalization risk, respectively. Conclusion: Nurses should be sensitive to the risk groups of hospital admission among patients with DM including no spouse, insulin injection, diabetic complications, low self-efficacy, and low HDL cholesterol.

Diabetes is a condition that can be brought on by a variety of different factors, some of which include, but are not limited to, the following: age, a lack of physical activity, a sedentary lifestyle, a family history of diabetes, high blood pressure, depression and stress, inappropriate eating habits, and so on. Diabetes is a disorder that can be brought on by a number of different factors. A chronic disorder that may lead to a wide range of complications. Diabetes mellitus is synonymous with diabetes. There is a correlation between diabetes and an increased chance of having a variety of various ailments, some of which include, but are not limited to, cardiovascular disease, nerve damage, and eye difficulties. There are a number of illnesses that are connected to kidney dysfunction, including stroke. According to the figures provided by the International Diabetes Federation, there are more than 382 million people all over the world who are afflicted with diabetes. This number will have risen during the years in order to reach 592 million by the year 2035. There are a substantial number of people who become victims on a regular basis, and a significant percentage of those people are uninformed of whether or not they have it. The individuals who are most adversely impacted by it are those who are between the ages of 25 and 74 years old. This paper reviews about various machine learning techniques used to detect diabetes mellitus.
