摘要目的 探讨潜艇训练对潜艇人员机体抗氧化能力的影响.方法 选择某潜艇部队海训艇、陆训艇、休整艇人员各50人,采集静脉血样,测定血常规、总抗氧化能力(T-AOC)、丙二醛(MDA)、γ-干扰素(IFN-γ)、红细胞溶血度和淋巴细胞增殖活性等指标.结果 海训艇、陆训艇、休整艇人员的T-AOC水平依次升高,分别为(15.38±3.11)、(18.81±2.45)、(20.93±2.95) U/ml,各组间差异有统计学意义(P<0.05);而MDA含量和红细胞溶血度则依次降低,分别为(2.56±0.70)、(2.12±0.53)、(1.77±0.56)nmol/ml和25.72%±1.67%、21.45%±1.02%、18.28%±1.37%,差异均有统计学意义(P<0.05).与陆训艇和休整艇人员比较,海训艇人员的IFN-γ水平[(31.89±3.52)pg/ml]和淋巴细胞增殖活性均降低,红细胞计数和血红蛋白含量则升高,各组间的差异均有统计学意义(P<0.05).结论 潜艇训练可降低潜艇人员的抗氧化能力,其中海上训练较陆地训练降低作用更为明显.

abstractsObjective To study the effect of the submarine training on the antioxidant ability of the submarine men. Methods 50 sea-training submarine men , 50 land-training submarine men and 50 resting submarine men were randomly selected from some submarine troops. The blood routine, the total antioxidative capacity (T-AOC), the content of malanydiadehyde (MDA) and the levels of IFN-γ in blood plasma, the hemolytic degree of RBC, the proliferation of peripheral-blood lymphocyte (PPL) of them were detected in each group. Results The T-AOC of the sea-training submarine men, the land-training submarine men and the resting submarine men significantly increased by turns [(15.38±3.11),(18.81±2.45 ),(20.93±2.95) U/ml], but MDA and the hemolytic degree of RBC significantly decreased by turns [(2.56±0.70), (2.12±0.53),(1.77± 0.56) nmol/ml and 25.72%±1.67%, 21.45%±1.02%, 18.28%±1.37%](P<0.05). Compared with the land-training submarine men and the resting submarine men, IFN-γ[(31.89±3.52) pg/ml] and the proliferation of PPL of the sea-training submarine men were significantly lower, whereas the red blood count (RBC) and hemoglobin (Hb) were significantly higher (P<0.05). Conclusion Submarine training, especially sea training, may decrease the antioxidant ability.
