摘要
用ZymosanA对中国对虾(Penaeuschinensis)血细胞进行体外刺激,用NBT还原法测定血细胞吞噬活动中产生O-2的产生;不同浓度2的过程。结果表明,中国对虾血细胞在经刺激诱导的吞噬活动中有明显的呼吸爆发和O-的ZymosanA对血细胞产生O-2的影响不同。ZymosanA在0.25~1.0mg/mL时随质量浓度的增加,产生O-2的量也增加,但当ZymosanA质量浓度继续增加到1.5和2.0mg/mL时,产生O-2的量反而下降。用同一浓度的ZymosanA对不同密度血细胞进行刺激产生O-2的强度也不同,随着密度的增加,血细胞产生O-2的量增加。SOD、NEM和碘代乙酰胺(Iodoacetamide)对血细胞吞噬过程中O-2的产生有抑制作用;Hg2+、Cr3+、Pb2+、Cu2+和Zn2+5种重金属离子也能抑制血细胞产生O-2;不同个体的中国对虾血细胞产生O-2的能力不同。NBT还原法测定中国对虾血细胞吞噬时产生的O-2可以作为检测对虾免疫状态的指标。
