Background: With open heart surgery(OHS), it has been recognized that many postoperative complications and postperfusion syndrome are associated with the activations of complements and leulocytes. Recently, some investigators also demonstrated that interlukin-6(IL-6) linked highly with postperfusion syndrome. The puropose of this study was to investigate the sequential changes of the IL-6 and to clarify each IL-6 relationship to the complements(C3, C4) and inflammatory response following cardiopulmonary bypass(CPB). Material and Method: To determine serum levels of IL-6, complements, leukocytes, and biochemistric markers of liver and renal function, blood samples were taken from th radial artery in 30 adult patients undergoing OHS with CPB. Result: Serum IL-6 levels incrased significantly at 10 minutes after CPB-on(CPB-10) in comparison with the control levels and reached the peak at CPB-off(p<0.05). Serum complement levels declined rapidly at CPB-10 and remained at the lower levels during CPB(p<0.01). Sequential changes of IL-6 levels had positive correlations with the changes of total leukocytes and neutrophil fractions(p<0.05), but had negative correlations with lymphocyte fractions(p<0.05). Changes of C3 related postively to monocyte fractions(p<0.05). Postoperative levels of total protein and albumin, decreased significantly in comparison with the control levels(p<0.01), while the postoperative levels of AST(aspartate transaminase) and bilirubin increased (p<0.01). At CPB-off, IL-6 levels had negative correlations with total protein and albumin levels(r=-0.60, -0.47 respectively, p<0.05), whereas C3 levels had positive correlations with albumin levels(r=0.40, p<0.05). IL-6 levels, as well as neutrophil fractions, had positive correlations with aortic clamp time(ACT) and total bypass time(TBT) (IL-6; r=0.82, 0.79 respectively, neutrophil fractions; r=0.50, 0.56 respectively, p<0.05), wheres lymphocyte frations and albumin levels had negative correlations whith ACT and TBT(lymphocyte fractions; r=-0.52, -0.58 respectively, albumin; r=-0.58, -0.55 respectively, p<0.05). Conclusion: These data showed that elevated production of serum IL-6 during CPB may play a pivotal role in systemic inflammatory responses and prologed CPB period may be assosiated with more sever postperfusion syndromes.

Pumpkin has long been used as traditional health materials in oriental medicine, pharmacy, medicine, and food industries in many countries. In this study, the water extract and two active components from tendril of young C. moschata Duch. were investigated on inflammation inhibitory activity. The water extract of young C. moschata Duch. showed high cell viability over 95% and it decreased the production of interlukin 6 (IL-6) and tumor necrosis factor (TNF-${\alpha}$) in the capacity of mouse bone marrow-derived macrophages (BMDM) upon lipopolysaccharide (LPS) stimulation. Also, isolated fraction (B4) suppressed the secretion of IL-6 and TNF-${\alpha}$. Among the domestically cultivated pumpkins, B4 fraction contained in the tendril part of them and it comprised of the order of tendril from Cucurbita pepo var. cylindrica, old of C. moschata Duch., and young of C. moschata Duch. These results suggest that water extracts of C. moschata Duch. and purified active compound, rutin, show anti-inflammation activity by suppression of the secretion of IL-6 and TNF-${\alpha}$. It can be applicable as pharmaceutical materials.

This study was conducted to investigate feeding effects of the high pressure boiled extracts (HPBE) of the Ogol chicken with herbs on glucose, hormones and immunological response (cytokine, specific antibody) of serum in the rat which fed either with normal feed (T$_1$), normal feed + herb HPBE (T$_2$), normal feed + Ogol chicken HPBE (T$_3$), normal feed + mixture of cross-bred Ogol chicken HPBE (T$_4$) hydrolyzed with Flavourzyme 0.1% for 35 days. During experimental period, there was a weak trend to have a higher glucose content for the T$_4$ group with 102.27${\pm}$5.95 mg/dL, but it was not significantly higher than other treatments. For insulin level, T$_1$ group showed numerically a slightly higher level with 6.79${\pm}$4.64 ${\mu}$IU/mL, but the difference was not significant in statistic term due likely to a large variation in comparison with other treatments. The treatments did not significantly alter testosterone level in rat plasma with 1.09, 1.46, 0.98, 1.13 ng/mL in T$_1$, T$_2$, T$_3$ and T$_4$, respectively. T$_4$ treatment increased the aldosterone level to a significantly (p<0.05) higher level (273.33 ng/dL) than other treatments. The extract treated rat showed a tendency in the cortisol level of lower levels than the control group, particularly, it was significantly (p<0.05) lower in T$_3$ group than other groups. T$_3$ and T$_4$ groups showed higher levels for interlukin-4 (IL-4) and anti-BSA IgG in immune cells and plasma. T$_2$, T$_3$ and T$_4$ treatments showed a slightly higher levels in v-interferon (INF-r) than the control, with a greater effect for T4 treatments. These results suggested that HPBE of the cross-bred Ogol chicken hydrolyzed with Flavourzyme increased immunological activity and decreased the concentration of cortisol and aldosterone hormones.
