This study is to investigate the effect of dietary mixed protein and L-carnitine supplementation on lipid metabolism in the rats fed high fat diet. Six experimental groups were organized and each group had eight Sprague-Dawley male white rats with the initial weight of around 180g. The six experimental groups were CO(supplemented with casein), CC(supplementedwith casein and cartinine), ISO(supplemented with isolated soy protein), ISC(supplemented with isolated soy protein and cartinine), CIM(supplemented with casein and isolated soy protein), and CIC(supplemented with casein, isolated soy protein and cartinine). Each group was supplemented with the experimental diet for four weeks, and carnitine contained 3efo of the diet. The results were as follows; 1. There was no significant difference in food intake among the experimental groups. The weight increased more significantly in the group supplemented with the mixed protein than in the group supplemented with casein(p<0.05).2. There was weight reduction effect by the supplementation of carnitine(p<0.05), however no weight reduction effect by the supplementation of carnitine was observed in the group supplemented with the mixed protein and isolated soy protein. 3. Food efficiency was lower in the group supplemented with the mixed protein than in the group supplemented with casein (p<0.05), however it was similar in the group supplemented with isolated soy protein.4. Serum total lipid and se겨m total cholesterol were lower in the group supplemented with mixed protein than in the group supplemented with casein(p<0.05). 5. There was no significant difference of serum triglyceride, HDL-cholesterol, and LDL-cholesterol among the experimental groups. 6. Liver triglyceride was the highest in the group supplemented with mixed protein (p<0.05), and there was no significant difference of liver total lipid and total cholesterol among the experimental groups. 7. In the groups supplemented with mixed protein, the level of liver TBARS showed the lowest when casein was supplemented(p<0.05), and there was no significant difference of GSH-Px activities among the experimental groups. In summary, when mixed protein was supplemented to the rats weight gain and food efficiency were similar with those in the group supplemented with isolated soy protein, however they were lower than those in the group supplemented with casein. The effect of carnitine on weight was not observed in the group supplemented with mixed protein and isolated soy protein, however it was observed in the group supplemented with casein. Serum Total lipid and total cholesterol were lower than those in the group supplemented with casein. Liver total triglyceride was high in the group supplemented with mixed protein, and the antioxidant effect was observed in the group supplemented with mixed protein.

This study was to investigate the cadmium removal effect of Korean green tea, black tea and oolong tea beverage on Cd administered rat, tissues and their excretions. Male Sprague-Dawley rats weighing 143±3.2g were divided into control and experimental groups. The control group were fed standard diet without cadmium . The experimental groups, which were fed standard diet containing 40 ppm Cd, were divided into 4 subgroups again , which were the groups given distilled water (CD group), 5% black tea (BT group), oolong tea (OT group ) and green tea (GT group), respectively. Five days before to sacrifice the rats, all 4 cadmium fed groups were supplied 1 ml of water with 600ppm Cd and control group were fed 1 ml of distilled water without Cd under the same dietary condition. After that, their excretion were collected separately for 3 days. In rat liver and kidney, accmulation of cadmium in 4 Cd administered groups were more than in control group and that of GT group was significantly less than CD group. In bone , also, accumulation of cadmium in 4 Cd administered groups was more than in control group and that of GT, OT,BT groups were much less than that of CD group. GT group was excreted more Cd in urine than Cd group. In feces, 3 tea feeding groups (BT, OT, GT group) were excreted Cd 1.7, 2.1, 2.4 times more than that of the CD group, respectively. We conclude that cadmium accumulations of GT feeding group in rat's liver, kidney and bone were much less than CD group , and the absorption and retention rate of GT group was significantly lower than CD group.

In this study three types of aggregation methods such as the Estimate-Talk-Consensus (ETC) process, the Estimate-Talk-Estimate (ETE) process, and as a new approach the Estimate-Talk-Leader's Estimate (ETLE) process are compared to find which one of the three group processes considered is more effective than others. We, also, investigate the effect of group size on the performance of the group processes. Some experiments were conducted. It was shown that both the ETC and the ETLE processes performed better than the ETE process in approaching correct estimates in this judgmental task. As the size group increased, only the ETC and the ETC processes were shown to result in positive effect.

Objective: Early environmental enrichment in life can improve cognition in animals. The effect of prenatal auditory stimulation on learning ability and fear level in chick embryos remained unexplored. Therefore, this study investigated the effect of prenatal auditory stimulation on the learning ability and fear level of chicks. Methods: A total of 450 fertilized eggs were randomly divided into 5 groups, including control group (C), low-sound intensity music group (LM), low-sound intensity noise group (LN), high-sound intensity noise group (HN) and high-sound intensity music group (HM). From the 10th day of embryonic development until hatching, group LM and group LN received 65 to 75 dB of music and noise stimulation. Group HN and group HM received 85 to 95 dB of noise and music stimulation, and group C received no additional sound. At the end of incubation, the one-trial passive avoidance learning (PAL) task and tonic immobility (TI) tests were carried out, and the serum corticosterone (CORT) and serotonin (5-HT) concentrations were determined. Results: The results showed that compared with the group C, 65 to 75 dB of music and noise stimulation did not affect the PAL avoidance rate (p>0.05), duration of TI (p>0.05) and the concentration of CORT (p>0.05) and 5-HT (p>0.05) in chicks. However, 85 to 95 dB of music and noise stimulation could reduce duration of TI (p<0.05) and the concentration of CORT (p<0.05), but no significant effect was observed on the concentration of 5-HT (p>0.05) and PAL avoidance rate (p>0.05). Conclusion: Therefore, the prenatal auditory stimulation of 85 to 95 dB can effectively reduce the fear level of chicks while it does not affect the learning ability.

Objective : The purpose of our study was to investigate the effect of JinlnWhaChul-tang-ga-wasong (JIN) on NDEA-induced liver tumorigenesis. Materials and Methods : We investigated the possible protective effects of Jininwhachul-tang-ga-wasong (JIN) as an anticancer against NDEA-induced liver injury in mice. Experimental mice were classified into 3 groups; normal, saline administered group (control group), and JIN extract (0.15g/kg/every other day) administered group (JIN group) after being injected with NDEA over 12 weeks. We examined the state of differentiation of these tumors and the effects of JIN after 6 weeks. To confirm the induction of apoptosis, the cells were analyzed by terminal deorynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay, acridine orange staining and flow cytometric analysis. To investigate inhibitory effect on the expression of COX-2 by JIN, we performed COX-2 immunohistochemistry and reverse transcription polymerase chain reaction analysis. Results : Body weights significantly decreased in the control and JIN groups compared with the normal group. The levels of cholesterol, hemoglobin and testosterone decreased in the control compared with the normal group. The level of estradiol significantly increased in the control compared with the normal group. The control group reacted with TUNEL assay more than the normal and JIN groups. Upon naked eye, light and electron microscopic examination, JIN improved the morphological and histopathological changes of the liver caused by NDEA-induced hepatic neoplasm. COX-2 immunoreactivity decreased in the JIN group compared with the control group, mRNA expression of the control group was greater than the normal and JIN groups. Conclusion : these results suggest the possibility that JIN may exert an anti-tumor effect on NDEA-induced liver tumorigenesis.

Purpose : Elastic taping is a therapeutic method, used for treatment of various musculoskeletal and neuromuscular deficits. However, there is limited evidence, of the effects of ankle elastic taping in neurologic patients. The purpose of this study, was to investigate the effect of elastic taping on gait, in the affected ankle area of chronic stroke patients. Methods : Subjects were randomized to receive 30 chronic stroke patients, who were 6 months old from the date of onset according to screening criteria. Group I showed ankle joint taping, and Group II had ankle muscle taping. Dynamic balance and temporal and spatial gait, were measured before taping application, and after 30 minutes of taping application. Results : Dynamic balance was measured using the Time up & Go test (TUG). There was statistically significant difference, between Group I and Group II (p<.05). There was no statistically significant difference, between Group I and Group II. Temporal and spatial gait were measured using GaitRite. In Group I, there was significant difference, before and after taping (p<.05). In Group II, there was no significant difference, before and after taping (p>.05). There was significant difference in Group I, between Group I and Group II (p<.05). Conclusion : Results suggest that intervention using elastic taping, may have a positive effect, on rehabilitation diversity and function in stroke patients. Based on this, it can be used for rehabilitation of stroke patients. Various studies on the application method, and effect of the application site as well as application time, should be continued with stroke patients.
