  • This study investigated the effects of magnetized water supplementation on blood glucose, DNA damage, antioxidant status, and lipid profiles in streptozotocin (STZ)-induced diabetic rats. There were three groups of 4-week-old male Sprague-Dawley rats used in the study: control group (normal control group without diabetes); diabetes group (STZ-induced diabetes control); and magnetized water group (magnetized water supplemented after the induction of diabetes using STZ). Before initiating the study, diabetes was confirmed by measuring fasting blood glucose (FBS > 200 dl), and the magnetized water group received magnetized water for 8 weeks instead of general water. After 8 weeks, rats were sacrificed to measure the fasting blood glucose, insulin concentration, glycated hemoglobin level, degree of DNA damage, antioxidant status, and lipid profiles. From the fourth week of magnetized water supplementation, blood glucose was decreased in the magnetized water group compared to the diabetes group, and such effect continued to the 8th week. The glycated hemoglobin content in the blood was increased in the diabetes group compared to the control group, but decreased significantly in the magnetized water group. However, decreased plasma insulin level due to induced diabetes was not increased by magnetized water supplementation. Increased blood and liver DNA damages in diabetes rats did significantly decrease after the administration of magnetized water. In addition, antioxidant enzyme activities and plasma lipid profiles were not different among the three groups. In conclusion, the supplementation of magnetized water not only decreased the blood glucose and glycated hemoglobin levels but also reduced blood and liver DNA damages in STZ-induced diabetic rats. From the above results, it is suggested that the long-term intake of the magnetized water over 8 weeks may be beneficial in both prevention and treatment of complications in diabetic patients.

  • This study conducted to evaluate effects of popped soybean on levels of ruminal peptides and blood amino acids in Holstein calves fed sudan grass hay as a forage source and popped (PSB) soybean as a concentrate supplement. At 0, 2, 4 and 6 h after feeding, rumen fluid and blood samples were collected from the rumen and jugular vein, respectively, and amino acids, peptides and other nitrogen-containing compounds in the rumen were analyzed. Ruminal pH tended to be higher in the RSB than in the PSB treatments, and declined upto 4 h after feeding, since then increased in both treatments. The concentrations of ammonia-N in all treatments increased upto 2 h after feeding, and then decreased gradually with time after feeding. The concentrations of ammonia N in the rumen were not significantly different between the treatments, however, those in RSB treatment appeared to be higher. Also, protein concentrations in the rumen were not significantly different between the treatments. Peptide productions were the highest at 2 h after feeding in the group fed RSB which is rapidly degradable in rumen, whereas those in the group fed PSB which is slowly degradable in rumen were maximized at 4 h after feeding. The concentration of total free essential amino acids in plasma was higher in the RSB treatment than in the PSB, but disappearance rates of these amino acids out of plasma was higher in the PSB treatment than in the RSB treatment. Disappearance rates of free non-essential amino acids in plasma were not significantly different between the treatments. Consequently, this study implies that the production of peptide and utilization of blood amino acid may be controlled by the modification of protein degradability.

  • The purpose of this study was to investigate the effects of garlic diet on blood coagulation in cholesterol-fed rats. 36 male rats were divided into six groups and fed experimental diet for three weeks. Two-levels (2% and 4%) of fresh and boiled garlic were supplemented to the stock diet with 2% cholesterol and 0.25% bile salt for the experimental diet. After the rats fed with experimental diets during 3 weeks, the whole blood coagulation time, the content of plasma fibrinogen, the fibrinolytic activity and the prothrombin time were measured. The results are summarized as follows; 1. Garlic diet have no influence on body weight and food consumption in rats. 2. In the case of cholesterol-fed group, the whole blood coagulation time was decreased 24.3% compared with the normal group(A). But garlic diet group(C) was similar to the normal group(A) and groupD-F was increased 4.9-11.5%. 3. The content of plasma fibrinogen of cholesterol-fed group was higher 114.5% than that of normal gropu(A). In the garlic diets(C-F) the contents of plasma fibrinogen were increased 33.1-63.8%. 4. The fibrinolytic activity of cholesterol diet was decreased 16.2% compared with the normal group(A) but was increased 10.9-44.5% compared to the garlic diets(C-F). 5. The prothrombin time of cholesterol-fed group was decreased 8.9% compared with normal group(A) but was increased 8.0-46.3% in garlic diets(C-F). As mentioned above, the garlic diets increased whole blood coagulation time, prothrombin time and fibrinolytic activity and decreased the content of fibrinogen. For that reason it is thought that the garlic diets have a anticoagulation effect regulating the fibrinogen synthesis in liver.

  • This study was designed to examine the effects of Allium hookeri (AH) on plasma blood glucose and fat profile levels in diabetic rats. Diabetes mellitus was induced in male Sprague-Dawley rats through injection of streptozotocin (STZ) dissolved in citrate buffer into tail veins at a dose of 45 mg/kg of body weight. Sprague-Dawley rats were then fed for 4weeks, with the experimental groups receiving a modified diet containing 5% or 10% powder derived from AH roots. The experimental groups were divided into four groups, consisting of a control group, STZ-control group, and diabetic fed with AH 5% & 10% treated groups. Rats' body weights, blood glucose, total cholesterol, HDL-cholesterol, triglyceride (TG), and free fatty acid (FFA) values in plasma were measured along with hematocrit (Hct) values and aminotransferase activities. Body weight losses were observed in the STZ-control group, whereas the STZ-AH group of diabetic rats gained weight. There was a significantly decrease in brain weight of the STZ-AH group but no significant differences in kidney and liver weights of the STZ-AH 5% & STZ-AH 10% groups compared to the STZ-control group. Blood glucose was significantly reduced in the STZ-AH 5% & STZ-AH 10% diabetic groups. There were no significant differences in total cholesterol and TG levels among the diabetic groups. HDL-cholesterol significantly increased while FFA significantly decreased in the STZ-AH 5% & STZ-AH 10% diabetic groups. The Hct level of the STZ-AH group was lower than that of the STZ-control group. Aspartate aminotransferase activity was significantly reduced in the STZ-AH 5% & STZ-AH 10% diabetic groups. These results indicate that supplementation with Allium hookeri root may have beneficial effects on diabetic complications as a potential therapeutic candidate.

  • Objectives : We investigated the effects of Ingecheonggeumdan(ICD) on body weight and examined whether blood lipid levels and visceral fat are inhibited by it in high fat diet-fed obese male mice. Methods : 8 weeks old, high fat diet-fed obese male mice were divided into 6 groups: C57BL/6N normal, control, ICD-1(150mg/kg), ICD-2(300mg/kg), ICD-3(600mg/kg) and orlistat(10mg/kg). After mice were treated with ICD and orlistat for 8 weeks, we measured body weight gain, food intake, feeding efficiency ratio, fat weight, plasma leptin and lipid levels. We also performed histological analysis for liver and fat on the mice. Results : Compared with controls, ICD and orlistat-treated mice had lower body weight gain and adipose tissue weight, the magnitudes of which were prominent in ICD-3. Compared with controls, ICD and orlistat-treated mice had lower blood leptin levels, the magnitude of which was prominent in ICD-3. Compared with controls, ICD and orlistat-treated mice had higher blood HDL-cholesterol and lower blood plasma LDL-cholesterol, free fatty acid and triglyceride levels, the magnitudes of which were prominent in ICD-3. Blood plasma AST and ALT concentrations were not changed by ICD and orlistat, indicating ICD and orlistat do not show any toxic effects. Consistent with their effects on body weight gain, the size of adipocytes and hepatic lipid accumulation were significantly decreased by ICD and orlistat. Conclusions : These results demonstrate that ICD and orlistat effectively reduce body weight gain, blood plasma LDL-cholesterol, free fatty acid and triglyceride levels and improves abdominal fat, the magnitudes of which were prominent in ICD-3.

  • Background Platelet-rich plasma (PRP) has more concentrated platelets than normal plasma (approximately 150-400${\times}10^3$ cell/dL). Platelets excrete several growth factors and cytokines that are associated with the healing and regeneration process. However, even though PRP is widely used, the mechanism or actual effect is presently unclear. Therefore, this study was performed to investigate the levels of growth factors and platelet concentration rate. Methods Autologous blood for preparing PRP was obtained from healthy subjects aged 25 to 35 years. The samples were divided into 4 experimental groups (inactivated whole blood, inactivated PRP, activated whole blood with thrombin and calcium chloride, and activated PRP). The platelet counts in the blood were analyzed and the growth factors were quantitatively measured. A statistical analysis was performed by using Dunn's multiple comparison test. Results In the blood cell analysis, the platelet count of the PRP group was approximately 4.25 times higher than that of the whole blood group. In the quantitative analysis of growth factors, the platelet-derived growth factor (PDGF)-AB, PDGF-BB, and transforming growth factor-${\beta}$ of the inactivated and activated PRP groups were higher than those of the inactivated and activated whole blood groups (P<0.05). Conclusions In this study, the platelet count and the levels of PDGF-AB and PDGF-BB in the PRP were determined. Further, more research is required on the bioactivity level of the growth factors secreted during the process of PRP preparation and the potency of growth factors that can be exerted physiologically in vivo.

  • The role of ascorbate as an antioxidant in the prevention and cure of disease that result from free radicals has been of considerable interest and controversy lately. As an antioxidant, we can expect it to protect against radiation damage caused by free radicals that are produced when radiation, especially sparsely ionizing radiation, interacts with living tissues. The plasma and whole blood concentration of ascorbate was analyzed before and just after the radiation therapy for the purpose of estimating the consumption amount of ascorbate during radiotherapy. Whole blood ascorbate was decreased from 1.82 mg/dl to 1.58 mg/dl, plasma ascorbate was decreased from 1.13 mg/dl to 1.08 mg/dl, and urine ascorbate was decreased from 9.33 mg/dl to 6.96 mg/dl after radiotherapy. Although the difference was not significant statistically, further human study should be followed to define the role of ascorbate as a radioprotector.

  • The blood proteins of ten reptilian species were studied by cellulose acetate elctrophoresis. Three members examined of the genus Agkistrodon have unusually similar patterns in plasma protein, hemoglobin, lactate dehydrogenase and malate dehydrogenase. On the basis of their electrophoretic patterns, it was concluded that Agkistrodon blomhoffii brevicaudus was closely related to the others. In general the plasma protein patterns reflect species specificity. Under the conditions employed, all snakes had a single hemoglobin band except Dinodon rufozonatum rufozonatum which showing two component patterns. Two members of the Chelonia showed four bands of hemoglobin. The zymograms indicated a distinct divergence in blood proteins of the Squamata from those of the Chelonia. The results reflected superficially the established phylogenies of these groups.

  • The purpose of this study was to analyze the intake of antioxidant vitamins and plasma TRAP concentrations of 60 maternal-infant pairs (30 in normal term delivery group, NT; 30 in preform group, PT) We also investigated the relationship between plasma TRAP levels of maternal-umbilical cord blood and pregnancy outcomes. Mean energy intakes of NT and PT pregnant women were 93.2% and 85.4% and their protein intakes were 113.3% and 110.9% of the recommended dietary allowance (RDA), respectively. The vitamin A intakes of NT and W pregnant women were 559.7 RE and 497.8 RE, which were less than RDA. While the vitamin E and C intakes of both NT and PT pregnant women were more than RDA. The maternal plasma TRAP level of PT was 1.41 mmol/l and that of was 1.50 mmol/l, which was significantly higher than TRAP level of PT (p < 0.05) . The umblical cord plasma TRAP levels of NT and PT were 1.44 mmol/l and 1.23 mmol/l, which indicates the significant difference between those two groups (p < 0.001) . In case of comparing the TRAP level of maternal and umbilical cord blood, there was no significant difference in NT pregnant women, however, in PT group maternal the TRAP level significant higher than that of umbilical cord (p < 0.001). The length of gestation and plasma TRAP level of maternal and umbilical cord showed a positive correlation. However, other parameters of pregnancy outcomes such as birth weight, weight gain, and Apgar score were not affected by the plasma TRAP levels. Based on these results, preform infants could have a risk of oxidative stress because of low plasma TRAP level.
