摘    要:探讨柿叶水提物对H22荷瘤小鼠和S180荷瘤小鼠的抗肿瘤作用。方法:建立H22荷瘤小鼠和S180荷瘤小鼠移植瘤模型,观察分析柿叶水提物各组对荷瘤小鼠的生命延长率、抑瘤率、胸腺指数、脾脏指数、肿瘤坏死因子(TNF-α)、超氧化物歧化酶(SOD)、丙二醛(MDA)、一氧化氮(NO)的影响。结果:柿叶水提物高、中、低剂量组及环磷酰胺组对H22荷瘤小鼠的生命延长率分别为34.05%,21.08%,5.95%,51.89%,对S180荷瘤小鼠的生命延长率分别为30.11%,17.74%,4.30%,45.16%。柿叶水提物高、中、低剂量组及环磷酰胺组的抑瘤率分别为42.08%,25.04%,23.95%,72.77%。柿叶水提物高剂量组的胸腺指数为(3.9±1.0)mg·g^-1,较氯化钠溶液组(3.0±1.1)mg·g^-1提高(P<0.05),柿叶水提物高剂量组的脾脏指数为(11.8±1.9)mg·g^-1,较氯化钠溶液组(9.2±1.6)mg·g^-1高(P<0.05)。柿叶水提物高、中、低剂量组TNF-α数值分别为(1.94±0.20),(1.89±0.54),(1.32±0.18)ng·ml^-1,较氯化钠溶液组(1.18±2.0)ng·ml^-1高(P<0.05)。柿叶水提物高、中、低剂量组SOD数值分别为(312.4±15.06),(304.14-16.1),(301.1±19.22)U·ml^-1,较氯化钠溶液组(278.1±11.02)U·ml^-1高(P<0.01或P<0.05)。柿叶水提物高、中、低剂量组MDA数值分别为(5.85±1.12),(6.31±1.17),(6.62±1.03)nmol·ml^-1,较氯化钠溶液组(7.26±0.62)nmol·ml^-1下降(P<0.01或P<0.05)。柿叶水提物高、中、低剂量组NO数值分别为(47.0±7.46),(51.2±9.07),(56.1±9.98)μmol·L^-1,较氯化钠溶液组(62.2±1.22)μmol·L^-1下降(P<0.01或P<0.05)。结论:柿叶水提物有一定的抗肿瘤作用,其作用机制可能与调节细胞因子TNF—α的?

Abstract:ABSTRACT Objective: To study the antitumor effects of water extract of persimmon leaves in H22-bearing mice and S180-bearing mice. Method: H22-bearing mice and S180-bearing mice were established and divided into five groups: normal saline (NS) group, cyelophosphamide (CTX) group, high, middle and low dose of water extract of persimmon leaves groups. The life prolongation rate , tumor inhibition rates, values of thymus index, spleen index, Tumor necrosis factor-α(TNF-α), superoxide dismutase(SOD), maleic dialdehyde(MDA) and nitrogen monoxidum(NO) were recorded, observed and analyzed. Result: The life prolongation rate of H22- bearing mice in high, middle, low dose groups and CTX group was 34.05%, 21.08%, 5.95% and 51.89%, respectively,and, the life prolongation rate of Sls0-bearing mice in high, middle, low dose groups and CTX group was 30. 11% , 17.74% , 4.30% and 45.16% respectively. The tumor inhibition rates in high, middle, low dose groups and CTX group were, 42.08% , 25.04% , 23.95% and 72.77%, respectively. The thymus index was significantly higher in high dose groups than that of in NS group[(3.9±1.0 ) rag. g^-1 vs. ( 3.0 ± 1.1 ) rag. g^-1, P 〈 0.051, corresponsively , the spleen index of high dose group was higher than that of NS group [ ( 11.8 ± 1.9 ) mg· g^-1 vs. ( 9.2± 1.6) mg· g^-1, p 〈 0.05 ]. TNF-α of high, middle and low dose groups [ ( 1.94 ± 0.20) ng· ml^-1, ( 1.89 ± 0.54) ng·ml ^-1 and ( 1.32 ± 0.18 ) ng· ml^-1] were higher than that of NS group [ ( 1.18 -+ 2.0) ng· ml -' ] ( P 〈 0.05 ). SOD of high, middle and low dose groups [ ( 312.4 ±15.06) U·ml^-1, ( 304.1 -+ 16.1 ) U·ml^-1, ( 301.1 ± 19.22 ) U·ml^-1 ] were higher than that of NS group [ ( 278.1 ± 11.02) U· ml^- 1 ] ( p 〈 0.01 or P 〈 0.05 ). Corresponsively, MDA was lower in high, middle and low dose groups[ (5.85 ± 1.12)nmol·ml ^-1, (6.31 ± 1.17) nmol·m1^-1 and (6.62 - 1.03) nmol·ml^-1, respective
