It is very important for hemodialysis in patients with end stage renal disease to obtain vascular access that resists repeated punctures and maintains adequate blood flow. This study was designed to indentify factors that may influence early patency rate of autogenous arteriovenous fistula. Material and Method: 49 cases in 47 patients who underwent radiocephalic fistula formation in our hospital from June 2002 through May 2003 were reviewed and analyzed. Result: The early patency rate was 79.6%. Age, sex, hypertension, and diabetes mellitus were not significant factors for patency. Body mass index and duration of hypertension and diabetes did not influence the early results either. Cephalic vein diameter measured preoperatively and blood flow at radio-cephalic fistula were significantly positive correlative factors. Groups with the vein diameter less than 2.7mm, or with the blood flow less than 100 mL/min had significantly lower early patency rate than the other groups. Conclusion: To improve early patency rate of radiocephalic fistula, large sized cephalic vein should be selected and if the intraoperative flow at radiocephalic fistula is less than 100 mL/min, another arteriovenous fistula formation should be considered.

Classification of peripheral leucocytes in Korean catfish (Silurus asotus) were performed. The leucocytes were classified on the basis of their morphological, cytochemieal and phagocytic characteristics. Four types of leucocytes were observed in the peripheral blood. Neutrophils were round and 12 - $15{\mu}m$ in diameter with round, oval or 2 - 3 segmented neuclei. Their cytoplam was stained whitish or grey. Lymphocytes were round and 5.5 - $8{\mu}m$ in diameter with large round neuclei which occupied most of the cells. Monocytes were round or irregular cells and 12 - $15{\mu}m$ in diameter with bean - shaped or irreular neuclei. Thrombocytes were oval or spindle - shaped cells with oval or spindle - neucle. The cells with greyish cytoplasm ranged 7.2 to $14.4{\mu}m$ in length and 5.8 to $7.2{\mu}m$ in width. Only neutrophils showed positive reaction in peroxidase and PAS. Neutrophils and monocytes showed active phagocytosis. As the results it is concluded that peripheral leucocytes of Koran catfish could be classified as lymphocytes, neutrophils, monocytes and thrombocytes.

This study was conducted to examine antioxidative activity and lipid composition from different parts and supplement flesh and skin of Codonopsis lanceolata in vivo. Forty six-week-old white Sprague Dawley rats were divided into 5 groups and fed with experimental diet for six weeks to measure antioxidant enzymes activities and lipid composition in blood and liver microsome. The activity of glutathione peroxidase in blood was high in all groups supplemented with Condonopsis lanceolata and the difference was observed in accordance with the supplemented part rather than the supplemented level. However, glutathione reductase activity and the content of malondialdehyde (MDA) in blood showed difference depending on the level of supplementation rather than the supplemented part. The content of liver MDA in all groups supplemented with Condonopsis lanceolata was lower than that in the control group. As the level of skin supplementation increased, an increase in glutathione peroxidase activity was also observed. Only in the group that 5% of Condonopsis lanceolata skin was supplemented, the glutathione reductase activity was higher than in the control group. Total cholesterol and LDL-cholesterol of blood in the group supplemented with Condonopsis lanceolata flesh or skin were significantly lower than those in control group. HDL-cholesterol in blood was high when the flesh of Condonopsis lanceolata was supplemented. Total cholesterol and triglyceride in liver of the group supplemented with Condonopsis lanceolata flesh or skin were significantly lower than those in control group. In summary, this animal test showed that the supplementation of Condonopsis lanceolata, flesh or skin, generally improved the antioxidative effect of diet and lipid composition.

This study was conducted to investigate the effects of dietary quercetin on growth performance, blood biochemical parameters, immunoglobulin, and blood antioxidant activity in broiler chickens. Three hundred twenty one-day old Ross broilers were divided 8 treatments (C(-), basal diet; C(+), basal diet with antibiotics; vitamin E 20 IU; vitamin E 200 IU; quercetin 20 ppm; quercetin 200 ppm; methoxylated quercetin 20 ppm; methoxylated quercetin 200 ppm) with 4 replicates and 10 birds per replicate. Birds were reared for 35 days and their feed intake and weight gain were measured weekly. At 35d, eight birds of average weight from each replicate were selected for blood collection and analysis. Weight gain of birds in the groups fed quercetin was higher when compare to NC but there was no significant difference. In the serum, creatinine, BUN and AST in quercetin groups significantly decreased compared to those of control (NC and PC) (P<0.05). The contents of IgA and IgM were significantly lower in quercetin groups than those of NC (P<0.05). SOD like activity and MDA content tended to decrease in quercetin groups, however, there was no significant difference among treatments. In conclusion, supplemental quercetin to poultry diet could be positive aspect on performance and blood metabolites. Optimum adding levels was more than 20 ppm.

This study was performed to investigate the influence of dietary and extract foods from A. capilliaris Thunberg on plasma and liver lipid metabolism in male Sprague-Dawley rats. For the experiment of liver and plasma lipid metabolism, Rats were find diets containing normal concentrations of fat or high concentrations of lard and two different preparations of A. capillaris Thunberg ; control diet (group C),50 mg/kg body weight A. capillary Thunberg methanol extract (group M), 6 g/kg diet A. capillary Thunberg dried powder (group P), high lard control diet (group L), 50 mg/kg body weight A. capillaris Thunberg with high lard (group LM) and 6 g/kg diet A. capillary Thunberg with hi\ulcorner lard (group LP). Effects of A. capillary Thunberg on plasma total cholesterol. High-density lipoprotein (HDL) cholesterol, Atherogenic index, triglyceride, plasma and liver peroxide contents, fatty acid composition of liver lipid and the distribution of fat droplets of liver. Supplementation of A. capillaris Thunberg resulted in lower plasma cholesterol, atherogenic index and triglyceride, and higher HDL-cholesterol in rats find high lard diets. However, these effects were not observed with low level of fat (groups C, M and P). A shift caused by feeding high lard diets in increased plasma and liver peroxides, saturated fatty arid composition of liver lipid and the more frequent distribution of fat droplets in liver could be reversed by feeding A. capillary Thunberg. This study suggests that A. capillary Thunberg co alter lipid metabolism in plasma and liver.

The effects of duration and time-dependent, high-intensity exercise on hematological properties and inflammation-related parameters in rats were studied. 20, 60, and 120 min of high-intensive exercise were performed daily for 8 weeks. None of the complete blood count (CBC) factors were affected by the exercise, except for the leukocyte concentration which, in the 20 min group, showed an increase of 47% compared to the control, but this was decreased after 60 min by 30% compared to the control. As exercise was performed for 60 min or longer, serum concentrations of $Fe^{++}$, unsaturated iron biding capacity (UIBC), and total iron biding capacity (TIBC) were significantly elevated in comparison to the control, where 20 min of exercise did not show any change. Both levels of interleukin-6 (IL-6), a pro-inflammatory cytokine, and interleukin-10 (IL-10), an anti-inflammatory cytokine in the serum, were elevated in response to the high-intensity exercise, however the rate of IL-6 increase was higher than the rate of exercise intensity increase, thus the offset of inflammation might be suggested. The concentration of nitric oxide (NO) in the serum became high in response to the exercise. Overall, the current observation suggests that inflammation-like responses to high-intensity exercise might be due to high circulation of blood flow and high oxygen requirement, resulting in systemic damages. However, under the current high-intensity exercise conditions, more than 20 min of exercise might not be suggested for health care purposes.
