对杂色鲍(HaliotisdiversicolorReeve)进行病毒悬液和PBS(对照)注射感染,研究其血清免疫因子SOD、ACP、AKP、MPO活性的变化,并对实验结果进行统计学分析。结果表明,(1)注射病毒悬液组SOD活性变化为逐渐上升,至8h后达到最高点,然后逐渐下降;对照组SOD活力呈下降趋势,8h后上升,12h后恢复至初始水平,二者结果差异均为显著或极显著(P<0 05或P<0 01)。(2)注射病毒悬液组ACP与AKP活性的变化为:36h前变化不大,48h后明显上升;对照组ACP和AKP活性变化不大,二者结果除了第48小时外,差异均不显著(P>0 05)。(3)注射病毒悬液组MPO活性在第1小时内上升,然后逐渐下降,第8小时下降到最低点,随后逐渐上升;对照组在第1小时内下降,然后逐渐上升,第12小时升至最高点,然后逐渐下降,48h后与正常鲍活性基本一致。t检验显示,这两组结果在第1、4、8、24、36、48h差异显著或极显著(P<0 05或P<0 01),在第2、12小时差异不显著。结果显示,在人工感染病毒48h内,杂色鲍体内的免疫因子发生了明显的变化,血清中SOD活性降低,ACP及AKP活性显著升高,MPO活性显著升高。 The virus suspension and PBS (control) injection in Haliotis diversicolor Reeve were used to investigate the changes of serum immune factors SOD, ACP, AKP and MPO, and the experimental results were statistically analyzed. The results showed that: (1) The SOD activity in the injected virus suspension increased gradually and reached the highest point after 8h, then decreased gradually. The SOD activity in the control group showed a downward trend, increased after 8h and returned to the initial level 12h later The differences were significant or highly significant (P <0.05 or P <0.01). (2) The changes of ACP and AKP activity in the injected virus suspension group were as follows: little change was observed 36h after injection, but obviously increased after 48h; the activities of ACP and AKP in the control group did not change much, except for the 48th hour (P> 0 05). (3) MPO activity in the injection of virus suspension increased in the first hour, then decreased gradually, then dropped to the lowest point in the eighth hour, and then gradually increased; the control group decreased in the first hour and then increased gradually; the twelfth hour rose To the highest point, and then gradually decreased after 48h and normal activity of the same basic abalone. t test showed that there was no significant difference between the two groups on the 1st, 4th, 8th, 24th, 36th and 48th hour (P <0.05 or P <0.01). The results showed that within 48 hours after artificial infection, the immune factors of M. heterophylla changed significantly, the activity of SOD in serum was decreased, the activity of ACP and AKP was significantly increased, and the activity of MPO was significantly increased.
