【摘要】 目的研究瘤内直接注射重组人5型腺病毒H101对B16黑色素瘤生长以及对手术后再次接种B16黑色素瘤细胞后肿瘤生长的影响。方法建立小鼠B16黑色素瘤动物模型。瘤内直接注射H101腺病毒,测量肿瘤体积,切除肿瘤,再次接种B16黑色素瘤细胞,观察肿瘤生长情况。结果细胞接种8 d后,全部小鼠均长出肿瘤。H101注射组肿瘤的体积在给药后3,6,9 d,都显著小于对照组。再次接种B16黑色素瘤细胞后,H101注射组肿瘤的生长速度也显著小于对照组。结论瘤内直接注射H101对B16黑色素瘤生长具有抑制作用,对手术后再次接种的肿瘤生长也具有抑制作用。更多还原

【Abstract】 OBJECTIVE To study the inhibition effects of direct intratumor injection of H101 on B16 melanoma in C57/BL6 mice and syngenetic mice rechallenged with parental cells.METHODS C57/BL6 mice bearing B16 melanoma were established by subcutaneous seeding B16 cell suspension at a dose of 2×106 cells per mouse.H101 was injected directly into the tumor in three continuous days at a dose of 5×106 pfu·mm-3·d-1.The tumors were surgically excised 7 days after the injection of H101.At 14 days after surgery,all animals were rechallenged on the opposite flank with parental B16 cell at a dose of 2×105 cells.The tumor size was calculated every day to observe the antitumor effect.RESULTS The average tumor volume in the H101 injection group was significantly smaller than that in control group,not only at D3,D6 and D9,but also at every day for the surgery mice rechallenged with parental cells.CONCLUSION The direct injection of H101 showed potent antitumor effect on B16 melanoma.更多还原
