Diabetes mellitus revealed a chronic disorder of lipid, carbohydrate and protein metabolism characterized by insulin deficiency, and a striking tendency toward development of atherosclerosis, microangiopathy, nephropathy, neuropathy and recently cardiomyopathy etc. The mechanism of heart failure in patients with diabetic cardiomyopathy is not clear but diabetic cardiomyopathy usually occurs in persons with long standing diabetes. After diabetes induced in made Sprague- Dawley strain rats by injection of streptozotocin(60mg/kg), cardiac tissue with hematoxylin-eosin and Masson's trichrome stain was examined at 3 days, 1, 2, 4, 6 weeks later under light microscope. The results were obtained as follows : 1. In H&E stain of control group, myocardiac cells were shorter than skeletal muscle cell, which was branched out and connected each other at terminal with striation, intercalated disk and nucleus at center of cell. 2. In MT stain of control group, a few of collagen fibrile were seen at periva scular interstium, but wasn't seen between skeletal muscle fiber, and cardiac muscle was seen in various size. 3. In MT stain of experimental group, increased collagen fiber deposition at perivascular interstiums were seen periodically. 4. In MT stain of experimental group, increased collagen fiber deposition at interstitial matrix between perimyocardiac cells were seen at 3 day, 4 weeks and 6 weeks after DM induction. 5. In H&E stain of experimental group, partial degeneration of myocardiac cells was seen after 4 weeks of DM induction. From above results, streptozotocin induced diabetes mellitus increased collagen around perivascular and between intercellular matrix in heart.

The hypoglycemic effect of Polygonatum odoratum var. Pluriflorum Ohwi was investigated after extracted with methanol. The methanol extract was fractionated into 4 layers ; hexane, chloroform, butanol and aqueous. Fifty male Sprague-Dawley rats(200-300g) were induced diabetes mellitus by the streptozotocin injection(45mg/kg B.W) into the tail vein and were divided into 5 groups ; diabetic control and 4 experimental groups. All groups of the rats were fed on a AIN-76 diet, and the 4 experimental groups were orally administered with each fraction(500mg/kg B.W) for 12 days and the diabetic control group was orally administered CMC. The body weight gain was monitered and the blood levels of glucose and cholesterol were measured. Levels of protein, triglyceride, and free fatty acid in plasma were analysed. The contents of protein, triglyceride and glycogen in liver and of protein and glycogen in muscle were also determined. The body weight gain was shown significantly higher in the H2O fraction group than that in the diabetic control group and the heart weight was greater in the CHCl3 group. The extents of blood glucose decrement were greater in the BuOH and H2O groups than that in the control group. The urinary glucose excretion was shown relatively small amount in the BuOH and H2O groups. The plasma cholesterol and protein levels were not influenced by these four fractions in diabetic rats. The liver glycogen level was significantly higher in the BuOH group. The results suggest that the orally administered BuOH and H2O fraction of Polygonatum odoratum var. Pluriflorum Ohwi exhibited hypoglycemic effect in streptozotocin induced diabetic rats.

This study were investigated the effects of physiologically active compounds isolated from Platycodon grandiflorum on streptozotocin-induced diabetic rats. The experimental groups were divided into six groups, normal, diabetic control (CM), and four experimental groups (inulin (IN), inulin + saponin (IS), oligosaccharide (OS), and total extract group (WE)). The rats have free access to water and diet. Experimental groups were administered orally with inulin (630 mg/mL), inulin (630 mg/mL) + saponin (25.2 mg/mL), oligosaccharide (367.5 mg/mL), and total extract (225 mg/mL) into the diabetic rats for 5 weeks after STZ injection; The levels of fasting blood glucose in diabetic control increased by 10.0% for 5 weeks, but the level of blood glucose in inulin and total extract groups decreased by 21.3% and 21.2%, respectively. The concentrations of total cholesterol and triglyceride in serum of diabetic rats fed physiologically activity compounds were lower than those in diabetic control rats. HDL-cholesterol was similar among all the groups. Weights of testicle and heart were lighter, while weight of kidney was significantly increased in diabetic groups than normal group. The concentrations of serum protein insulin and albumin in diabetic groups were significantly decreased compared with those of the normal group. Urinary glucose excretion was decreased in inulin group than other diabetic groups.

This study was carried out to investigate the effect of Lentinus edodes which were harvested at different times of maturity on blood glucose and lipid levels in diabetic mice. The diabetic KK mice were fed diets supplemented with Lentinus edodes harvested early (LE) or late (LL) for eight weeks, and control (CO) mice were fed regular diet without Lentinus edodes. Diet intake, body weight, organ weight, blood glucose and serum lipid levels were measured. The mice which were fed diets supplemented with LE and LL showed significantly lower body weights compared to the CO group. There were no significant differences in the diet intake and the weights of different organs including liver, heart, kidneys, and epididymal fat pad among three different groups. Furthermore, the concentrations of serum triglycerides and total cholesterol were significantly lower in LE and LL groups compared to the CO group. These results clearly demonstrate that Lentinus edodes, regardless of their harvested period reduced body weight and serum lipid without affecting blood glucose level in diabetic mice.

Dioscorea japonica Thunb its effects has been used in f31k remedies f9r various purposes including treatment of diabetes, on hypoglycemic actiity and energy metabolism were investigated. The plant was extracted with methanol(MeOH) and fractionated into four layers hexane, chloroform(CHCI$_3$), butanol(BuOH), and $H_2O$. Diabetes mellitus was induced in male Sprague-Dawley rats by the injection of streptozotocin(STZ) into tail vein at a dose of 45mg/kg body weight(BW). Sprague-Dawley male rats weighing 160-200g were divided into five groups a diabetic control and four experimental groups such as hexane group, CHCl$_3$ group, BuOH group, and $H_2O$ group. The rats of all groups were fed on a AIN-76 diet and the four experimental groups were orally administered each fraction(500mg/kg BW) for 12 days. The diabetic control group was orally administered 5% carboxymethyl cellulose. The body weights were monitored and the concentrations of blood glucose were determined. The levels of glycogen and protein in liver were also measured. The plasma levels of cholesterol, triglyceride (TG), and fee fatty acid(FFA) were also analysed. The body weight gain was higher in the $H_2O$ group than in the control group. Heart weight was significantly reduced by administrations of Dioscorea japonica Thunb. The extents of blood glucose decrement in BuOH and $H_2O$ group were greater than that found in the control group. The muscle protein levels showed significantly higher amounts in all experimental groups. Glycogen levels were higher in the BuOH group than in the control group. The levels of TG were decreased in all experimental groups and the levels of plasma FFA were lower in the BuOH group. The plasma cholesterol levels were not influenced by these four fractions in diabetic rats. These results suggest that the orally administered H2O fraction of Dioscorea japonica Thunb exhibited hypoglycemic effects in STZ induced diabetic rats. (Korean J Nutrition 31(7) : 1093-1099, 1998)

Purpose: Diabetic foot ulcers are closely related to body surface heat, which can be affected easily by temperature differences. This study examined the correlation between the healing process of diabetic wounds and abnormal diurnal temperature through an animal study. Materials and Methods: Rats in the abnormal diurnal temperature group and control group were given a 10 mm sized full-thickness skin ulcer. Wound size progression was observed in both groups. H&E and Masson's trichrome staining was performed at 14 days after wound formation, and the number of vessels per unit area and histology analysis were performed. The changes in the ulcer were measured through three dimensional cross-section area using INSIGHT^® devices. Results: The wound recovery period (granulation ingrowing) was 24 days in the abnormal diurnal temperature model and 20 days in the control group. The thickness of scar tissue was 402±23.19 ㎛ in the control group and 424.5±36.94 ㎛ in the diurnal temperature model. Neovascular formation was counted as 5.1±0.97 for the control group and 4.16±0.94 for the diurnal temperature model group. Conclusion: Delayed and inferior diabetic wound healing was observed in the abnormal diurnal temperature group, which was characterized by greater diurnal variations than the typical growth environment.

Maternal diabetes is known to have teratogenic effects which increase the risk for congenital anomalies, such as caudal dysplasia, cardiac defects, hydronephrosis, and small left colon syndrome. Infants of diabetic mothers have a 10-fold higher frequency of anomalies in the central nervous system and a 5-fold higher frequency of congenital heart defects. However, jejunal atresia combined with multiple anomalies of the face, ears, and hands has rarely been reported. Herein we report a neonate born to a diabetic mother, who had hemifacial microsomia, displacement of the lacrimal ducts, polydactyly of the right hand, microtia of the right ear and proximal jejunal atresia presenting as bile regurgitation on the 1st day of life.

Purpose: To evaluate the effects of continuous self monitoring of blood glucose (SMBG) on glycemic control in diabetic patients. Methods: Among the diabetic patients who visited the department of internal medicine in H hospital from April 1 to October 27 2008, 76 patients were divided into the experimental group (n=39) and control group (n=36). The experimental group was required to measure blood glucose levels at least twice every other day using SMBG; their compliance was aided by weekly telephone reminders for 3 months after discharge. Glycated hemoglobin, fasting blood sugar and postprandial 2 hours glucose level, triglyceride and high density lipoprotein were measured before and after the study. Results: Baseline characteristics were not different between the experimental and control groups. Three months later, there was a significant difference in postprandial glucose between the two groups (t=-2.042, p=.045). Conclusion: There was significant improvement of glycemic control after the use of continuous SMBG, suggesting its value in strict glycemic control and the merit of an aggressive education program.

To investigate the antihyperglycemic and antihyperlipemic effect of 80% ethanol extract of Schizandra Chinensis fruit, we induced diabetes in the rats with streptozotocin (STZ) and administered schizandra extract or Acarbose to diabetic rats for 21 days by oral administration. Consequently, the groups treated using schizandra extract decreased blood glucose levels more 39% than no treatment group and the case of Acarbose group was decreased it about 21%. The concentration of cholesterol, triglyceride and LDL-C in blood was also decreased while treating schizandra extract, on the other hand, HDL-C concentration was significantly increased it about 26%. Those results induced that anti-atherogenic index (AAI) in blood was improved more than 82% level like normal condition, especially in treatment of schizandra extract 100 mg. The lipid profiled in feces was likewise showed apparent tendency to decrease and food efficiency ratio of diabetic rats was became higher for treatment with schizandra extract, but Acarbose group had low efficiency in compared with the result of glucose level and lipid profile in blood. As a result, schizandra extract is regard a good medicine for diabetes due to improve physical constitution, blood glucose and lipid level caused hyperglycemia and suggest that schizandra extract has real effects on the diabetes complication as atherosclerosis, coronary heart disease, high blood pressure.
