Diabetic neuropathy may affect every part of the nervous system with the possible exception of the brain. While it is rarely a direct cause of death, it is a major cause of morbidity. Distinct syndromes can be recognized, and several different types of neuropathy may be present in the same patient. The most common picture is that of peripheral polyneuropathy. Usually bilateral, the symptoms include numbness, paresthesias, severe hyperesthesias and pain. The pain, which may be deep-seated and severe, is often worse at night. In this case, chief complaints were numbness and paresthesia of lower extremities and the symptoms were improved through Oriental medical treatment.

Diabetic patients need nutritional education more than those suffering from other diseases because of the necessity of controlling blood glucose levels with dietary treatment. The purpose of this study was to find out the effectiveness of nutrition education on diabetes control and antioxidant status, both of which are related to diabetic complications. Thirty (15 males and 15 females) type 2 diabetes mellitus patients aged $66.7{\pm}8.8$ years participated in a 4-week nutrition education program. Nutrient intakes, blood glucose level, antioxidant status, and DNA damage were evaluated before, immediately after, and three months after the education program. Changes in those parameters over time were analyzed using repeated-measures analysis of covariance. Over time, HbA1c (p=0.000), plasma total cholesterol (p=0.002), plasma thiobarbituric acid related substances (TBARS; p=0.000), and leukocyte DNA damage (p=0.000) significantly decreased; plasma retinol (p=0.001), plasma tocopherol (p=0.000), erythrocyte catalase (CAT; p=0.000), and erythrocyte glutathione peroxidase (GPx; p=0.000) significantly increased. In an evaluation of nutrient intakes by Dietary Reference Intakes for Koreans (KDRI), energy (p=0.009), phosphorus (p=0.033), sodium (p=0.001), potassium (p=0.019), zinc (p=0.043), riboflavin (p=0.050), folic acid (p=0.048) and vitamin C (p=0.008) intakes had significant positive changes. In a correlation analysis of the biochemical and nutritional changes resulting from the education program, plasma TBARS were negatively correlated with potassium (r=-0.418, p<0.05), iron (r=-0.443, p<0.05), riboflavin (r=-0.432, p<0.05), and folic acid (r=-0.446, p<0.05) intakes, while plasma retinol was positively correlated with energy (r=0.543, p<0.01), protein (r=0.543, p<0.01), phosphorus (r=0.425, p<0.05), iron (r=0.485, p<0.05), zinc (r=0.570, p<0.01) and niacin (r=0.510, p<0.05) intakes. Erythrocyte CAT was positively correlated with folic acid intake (r=0.605, p<0.01). From these results, we suggest that an improvement in nutrition resulting from a diabetic education program for type 2 diabetes patients led to improvement in their antioxidant status, also possibly reducing complications resulting from diabetes.

Gastic emptying scan in diabetic patients is widely used to assess the degree of motility disturbance and the symtoms such as nausea, vomiting, bloating, abdominal pain and early gastric fullness which we can't find anatomic lesion by fiberoscopic or barium study In order to determine the relationship among diabetic gastropathy, neropathy, retinopathy and disease duration, gastric emptying scan using $^{99m}Tc-tin$ colloid labeled scramble egg in hamburger was performed in 10 healty male controls and 50 diabetic patients which were subdivided to no neuropathy, peripheral neuropathy and autonomic neuropathy groups according to the degree of diabetic neuropathy and no retinopathy, background retinopathy and proliferative retinopathy groups according to the degree of diabetic retinopathy. After medication of cisapride for 2 weeks, we observed the presence of improvement of gastric motility in diabetics. The results were as following: 1) In controls, gastric emptying time (GET1/2) was $75{\pm}13.6$ min and 2 hour gastric retension rate (GRR2) was $32{\pm}11.1%$. 2) In diabetics, GET/2 was prolonged more than 2 hours and GRR2 was $58{\pm}23.1%$. According to degree of neuropathy, GET1/2 was prolonged more than 2 hours in all three groups and GRR2 was $54{\pm}24.1%$ in no neuropathy group, $57{\pm}24.3%$ in peripheral neuropathy group and $69{\pm}24.6%$ in autonomic neuropathy group. According to degree of retinopathy, GET1/2 was $110{\pm}23.4$ min in no retinopathy group and prolonged more than 2 hours in other two groups and GRR2 was $45{\pm}21.6%$ in no retinopathy group, $71{\pm}19.7%$ in background retinopathy group and $73{\pm}21.5%$ in proliferative retinopathy group. 3) After cisapride medication for 2 weeks, GET1/2 and GRR2 were improved as $90{\pm}14.6$ min and $40{\pm}13.8%$ (initial GET1/2 and GRR2 were above 2 hours and $61{\pm}15.4%$). We can conclude from above findings that gastropathy in diabetic neuropathy suggesting main underlying factor in motility disorder The degree of retinopathy and disease duration were correlated with severity of gastropathy in diabetics. From the results of gastric emptying scan, we can conclude that cisapride was useful drug for improving diabetic gastropathy and gastric emptying scan was valuable for assessing severity of diabetic gastropathy as non-invasive method.

Purpose: We performed this study to evaluate the changes of gallbladder ejection fraction (GBEF) in diabetic patients with or without autonomic neuropathy. Materials and Methods: This study included 37 diabetic patients (25 women, 12 men, mean age 51 years) and 24 normal controls (10 women, 14 men, mean age 38 years). After intravenous injection of 185 MBq of $^{99m}Tc$-DISIDA, serial anterior abdominal images were acquired before and after fatty meal. Regions of interest were applied on gallbladder and right hepatic lobe on 60 and 90 minute images to calculate GBEF. Results: GBEF was significantly reduced in diabetes with autonomic neuropathy ($43{\pm}12.3%$) and without autonomic neuropathy ($57.5{\pm}13.2%$) compared with normal controls ($68{\pm}11.6%$, p<0.05). And also, GBEF was significantly reduced in diabetes with autonomic neuropathy compared with diabetes without autonomic neuropathy (p<0.05). Fasting blood glucose level, age, sex, hemoglobin Alc, body mass index, serum lipid level were not different in these two diabetic patient groups (p>0.05). When 50.2% of GBEF was used as the criteria for diabetic autonomic neuropathy, the sensitivity and specificity were 80%, 76.5%, respectively. The area under receiver operating characteristic curve was 0.846. Conclusion: GBEF of diabetic patients with autonomic neuropathy was significantly reduced than that of diabetic patients without autonomic neuropathy.
