To study the effects of substances in paeonia seeds (Paeonia lactiflora Pall.) on lipid metabolism, crude methanol extract and secondary ether-soluble fraction out of defatted methanol extract and trans-resveratrol were prepared from the seeds and added to 0.5% (w/w) cholesterol diets for rats. Male Sprague-Dawley rats weighing 120$\pm$11 g were divided into six experimental groups: control group with no extra supplement, 0.1% (MP1) and 0.2% methanol extract (MP2) supplemented groups, 0.05% (EP1) and 0.1% ether-soluble fraction (EP2) supplemented groups and 0.02% resveratrol supplemented group. Experimental diets were fed ad libitum to the rats for 3 weeks. Body weight gains and food efficiencies were not different among the six experimental groups. Relative liver weights were lower in EP2 group compared to those in control group, but serum GOT and GPT levels of paeonia seed groups including trans-resveratrol group were not different from those of the control group. Serum total cholesterol levels reduced in EP2 and resveratrol groups but HDL-/total cholesterol ratios significantly increased in the four paeonia groups except EP1 group compared with the control group and serum triglyceride level lowered only in EP2 group than that of the control. However, liver cholesterol levels lowered in the five paeonia groups but triglyceride level lowered in MP2, EP1, EP2 groups than that of the control group. Fecal cholesterol excretion significantly increased in MP2, EP1, and EP2 groups than that of the control group, but bile acid excretions were not changed except that a reduction in EP2 group. These results suggest that paeonia seeds contain substances improving serum lipid status mostly via HDL pathway and resveratrol as monomer is one of the effective components but others including resveratrol oligmer are involved in the lipid improving effect.

Background: Interrupted aortic arch is a rare congenital heart anomaly which still shows high surgical mortality. In this study, we investigated the causes of and the risk factors for mortality to improve the surgical outcomes for this difficult disease entity. Material and Method: From 1984 to 2004, 42 patients diagnosed as IAA were reviewed retrospectively. Age, body weight at operation, preoperative diagnosis, preoperative PGE1 requirement, type of interrupted aortic arch, degree of left ventricular outflow stenosis, CPB time, and ACC time were the possible risk factors for mortality. Result: There were .14 hospital deaths. Preoperative use of PGE1, need for circulartory assist and aortic cross clamp time proved to be positive risk factors for mortality on univariate analysis. Preoperative left ventricular outflow stenosis was considered a risk factor for mortality but it did not show statistical significance (p-value=0.61). Causes of death included hypoxia due to pulmonary banding, left ventricular outtract stenosis, infection, mitral valve regurgitation, long cardiopulmonary bypass time and failure of coronary transfer failure in TGA patients. Conclusion: In this study, we demonstrated that surgical mortality is still high due to the risk factors including preoperative status and long operative time. However preoperative subaortic dimension was not related statistically to operative death statistically. Adequate preoperative management and short operation time are mandatory for better survival outcome.

This study was designed to investigate the effects of enzymatic hydrolysates (EH) from Hamcho (Salicornia herbacea L.) on blood glucose and serum lipid status in streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into normal and 5 diabetic groups. The diabetic groups were fed enzymatic hydrolysate-free control (DM) diets or diets supplemented with 0.02% (DM-2), 0.04% (DM-4), 0.08% (DM-8), and 0.16% (DM-16) of enzymatic hydrolysate for 4 weeks. Body weight gains were lower in five diabetic groups than that of the normal group. Blood glucose was decreased in EH-supplemented groups as compared to the normal group, and especially the lowest blood glucose levels were found in DM-4 and DM-8 groups. Activities of three disaccharidase in the middle part of the intestine, such as maltase, sucrase and lactase, in EH-supplemented groups were significantly lower than those of DM group. There was no significant differences in the activities of glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT) among all experimental groups. Serum triglyceride in DM group was significantly increased as compared to the normal group, but those of EH-supplemented groups were decreased to the normal level. Total cholesterol level in DM group was higher than EH-supplemented groups and normal group, but that of DM-16 group was significantly decreased to the normal level. HDL cholesterol level in DM group was significantly decreased compared to the normal group, but that of EH-supplemented groups was increased to the normal level. These results suggest that enzymatic hydrolysate from Hamcho has hypoglycemic and hypolipidemic effects on STZ-induced diabetic rats and may be useful as a dietary supplement for the treatment of diabetes.

This study was conducted to determine riboflavin status of young healthy Korean women. Eight subjects consumed general Korean diet for 3 weeks. Riboflavin intake was measured during the period and Erythrocyte Glutathione Reductase Activity coefficient (EGRAC) was analyzed at the end of experimental period. The subjects who showed EGRAC value above 1.20 were supplemented 6 mg riboflavin per day for 1 week. The average age of subjects was 22.1 years old, height was 154.4cm, weight was 49.2kg, chest circumference was 81.2cm, the sum of skinfold thickness of 3 parts was 79.5mm and Body Mass Index(BMI) was 20.6. Hemoglobin concentration was 13.0g/100ml, hematocrit value was 44.0% A/G ratio was 1.4, and the activity of sGOT, sGPT, alkaline phosphatase was 14.3, 11.0 and 6.5, respectively. The average daily intake of energy, protein and riboflavin was 1745kcal, 56.1g and 1.14mg, respectively. The mjor source of riboflavin were milk, egg, Korean cabbage, rice, beef and so on. The average EGRAC value was 1.2748. percentages of subjects who showed EGRAC value above 1.20 was 65.2%. After oral administration of 6mg riboflavin, the EGRAC value of all these subjects was returned to normal range. Riboflavin intake was correlated positively with energy as well as protein intake, and correlated negatively with EGRAC value. However, riboflavin intake per 1,000kcal was not correlated with EGRAC value.

Purpose: The purpose of this master's thesis is to utilize basic data in order to improve the quality of life of cancer patients who received radiation therapy after analysing related factors that influence patient's quality of life and obtaining information about physical, mental problems of patients. Materials and Methods: By using a structured questionnaire about various characteristics and forms of support, I carried out a survey targeting 107 patients that experienced radiation therapy at a university hospital in the Daejeon metropolitan area from July 15 to August 15, 2010 and analysed the factors influencing quality of life. Results: In case of pain due to disease, 65.15 and painless 81.87 showed a high grade quality of life. As body weight decreases, the quality of life become lower. When the grade of quality of life according to economic characteristics was compared, all items except treatment period showed a difference (P=0.000). When the score of social support, family support, medical support and self-esteem was low, the mark of quality of life showed respectively 61.71, 68.77, 71.31, and 69.39 on the basis of 128 points. When the score of support form was high, the mark of quality of life showed 90.47, 83.29, 90.40, and 90.36 (P<0.05). When analyzing the correlation between social support, family support, medical support and self-esteem and the degree of quality of life, social support was 0.768, family support 0.596, medical support 0.434, self-esteem 0.516. They indicated the correlation of meaningful quantity statistically (P<0.01). The factors that improved the quality of life were married state, having a job and painless status. As monthly income increases, the quality of life was also much improved (P<0.05). Among the factors related to quality of life, social support and medical support and higher self-esteem scores of the quality of life score increased 0.979 point, 0.508 points and 1.667 point, respectively. Conclusion: In conclusion, the quality of life of cancer patients that received radiation treatment is related to social support, medical support and self esteem. Self-esteem is an important factor that influenced quality of life, so if government offers works that doesn't affect patient's health, they are a useful method that maximize self-esteem and lessen their financial burden at the same time. Along with these policies, the developments of the attention of medical and the program for cancer patient's family are needed for the purpose of improving quality of life of cancer patients. Lastly, medical team, patients and family have to cooperate in harmony to overcome difficulties of cancer patients.

The objective of this study was to evaluate tire effects of modified triple pelvic osteotomy(TPO). The procedures of modified TPO were composed of two iliac osteotomies and a pubic symphysiotomy at a tittle. Medical records of modified TPO treatment on 36 dogs and of unilateral TPO on 7 dogs were reviewed on the basis of signalment, body weight, operation time, Healing time of osteotomy sites and complications from October 2002 to September 2004. The values of clinical status and hip dysplasia, Norberg angle, percentage of femoral head coverage and pelvic diameter from radiographs taken preoperative, immediately postoperative, 2, 4, 8, 12 and 24 weeks after operation, respectively, were measured. In .unilateral TPO, the dogs could start standing without assistance from $3.0\pm1.0days$ and walking from $8.3\pm0.6days$ (n=3). Mean clinical grade before and 24 weeks after surgery were $2.2\pm0.42$(n=6) and $3.5\pm0.7$ (n=2), respectively. Mean operation time was $107.3\pm38.9$ minutes (n=4). In modified TPO, the dogs were seen to staff standing without assistance from $4.9\pm3.7$ days and walking from $7.3\pm4.8days$ (n=25). Mean clinical grade before surgery and 24 weeks after surgery were $2.3\pm1.5$ (n=27) and $3.2\pm0.7$)(n=9), respectively. Postoperative clinical grade significantly improved against preoperative clinical grade (P<0.01). Mean operation time was $143\pm42.8$ minutes (n=24). This was shorter than time f3r twice unilateral TPO. By comparison with preoperative values, postoperative mean radiographic grade, percentage of femoral head coverage and Norberg angle measured at the recheck time point significantly increased (P<0.01). Mean postoperative pelvic diameter was significantly larger than preoperative pelvic diameter in modified TPO (P<0.01) but not in unilateral TPO. These results indicated that modified TPO was effective technique for the treatment of hip dysplasia in dogs.

Plantago asiatica L. (PA), which is widely distributed in Korea, Japan and China, has traditionally been used as a popular folk medicine for the treatment of liver diseases. A variety of activities of PA was reported, that is hepatoprotective, anti-inflammatory, anti-glycation and anti-oxidant effect. Ferric nitrilotriacetate (Fe-NTA) is a potent nephrotoxic agent and has been reported to induce renal proximal tubular necrosis. In the present study, pre-treatment with PA extract (PAE) in Wistar rat followed by Fe-NTA i.p. treatment (13.5 mg Fe/kg body weight) was performed to detect the renal protective effect of PAE. Only Fe-NTA treated group showed increases in the level of serum blood urea nitrogen (BUN) and serum creatinine (Cr), and renal tissue malondialdehyde (MDA), product of lipid peroxidation. Moreover, the level of biomarkers indicate the antioxidants status, reduced glutathione (GSH), glutathione-S-transferase (GST) and glutathione reductase (GR) were decreased. However, PAE pre-treated group showed decreases in the levels of serum BUN, serum Cr and renal tissue MDA in concentration dependent manner and increases in the level of GSH, GST and GR. These results are significantly different (p < 0.05) to the other groups. Our data suggest that PAE may be used as an chemopreventive material against Fe-NTA-mediated renal oxidative stress.
