目的:分析比较 BALB/c 和 CBA 小鼠局部淋巴结试验结果。方法将已知致敏性的4种化学物(2,4-二硝基氯苯、丁子香酚、己基肉桂醛和异丙醇)和未知致敏性的3种化妆品对 BALB/c 和 CBA 小鼠连续染毒3 d,第5天腹腔注射示踪剂 BrdU,第6天分离颌下淋巴结制取单细胞悬液,用 ELISA 试盒检测细胞增殖。结果2,4-二硝基氯苯、丁子香酚、己基肉桂醛和3号烫发剂两品系结果均呈致敏阳性,3种化学物 EC1.6值分别为0.08%(极强)、4.02%(中)、6.68%(中)(BALB/c)和0.07%(极强)、6.08%(中)、8.89%(中)(CBA);异丙醇、1和2号化妆品两品系结果均为致敏阴性,SI 均小于1.6。结论两品系小鼠局部淋巴结试验结果较一致,BALB/c可替代 CBA 小鼠应用于化学物和化妆品的致敏性评价。
目的:分析比較 BALB/c 和 CBA 小鼠跼部淋巴結試驗結果。方法將已知緻敏性的4種化學物(2,4-二硝基氯苯、丁子香酚、己基肉桂醛和異丙醇)和未知緻敏性的3種化妝品對 BALB/c 和 CBA 小鼠連續染毒3 d,第5天腹腔註射示蹤劑 BrdU,第6天分離頜下淋巴結製取單細胞懸液,用 ELISA 試盒檢測細胞增殖。結果2,4-二硝基氯苯、丁子香酚、己基肉桂醛和3號燙髮劑兩品繫結果均呈緻敏暘性,3種化學物 EC1.6值分彆為0.08%(極彊)、4.02%(中)、6.68%(中)(BALB/c)和0.07%(極彊)、6.08%(中)、8.89%(中)(CBA);異丙醇、1和2號化妝品兩品繫結果均為緻敏陰性,SI 均小于1.6。結論兩品繫小鼠跼部淋巴結試驗結果較一緻,BALB/c可替代 CBA 小鼠應用于化學物和化妝品的緻敏性評價。

Objective To analyze and compare results of local lymph node assays (LLNA) between BALB/c and CBA mice.Methods 4 chemicals (2,4-dinitrochlorobenzene, eugenol, hexyl cinnamic aldehyde and isopropanol) and 3 cosmetics were applied to the dorsum of both ears of Balb/c and CBA mice for three consecutive days.BrdU solution was injected inter-peritoneally on day 5.On day 6, the bilateral draining auricular lymph nodes were excised and made into single cell suspension, the lymph cell proliferation was measured by BrdU ELISA kit.Results 2,4-dinitrochlorobenzene, eugenol, hexyl cinnamic aldehyde and NO.3 perm agent pretended positive for both strains, EC1.6 values of three chemicals were found to be 0.08% (very strong), 4.02% (moderate), 6.68% (moderate) and 0.07% (very strong), 6.08% ( moderate), 8.89% ( moderate) for BALB/c and CBA mice respectively.Isopropanol, NO.1 and NO.2 cosmetics pretended to be non-sensitizers with SI <1.6 for both strains.Conclusion This study showed that BALB/c mouse was essentially equal to CBA for LLNA: BrdU-ELISA, which suggested that BALB/c mouse was a good alternative for CBA used in chemicals and cosmetics allergenic evaluation.
