A marine bacterium,Pseudoalteromonas sp.BC228 was supplemented to feed in a feeding experiment aiming to determine its ability of enhancing the digestive enzyme activity and immune response of juvenile Apostichopusjaponicus.Sea cucumber individuals were fed with the diets containing 0 (control),105,107 and 109 CFU g-1 diet of BC228 for 45 days.Results showed that intestinal trypsin and lipase activities were significantly enhanced by 107 and 109 CFU g-1 diet of BC228 in comparison with control (P〈0.01).The phagocytic activity in the coelomocytes of sea cucumber fed the diet supplemented with 107 CFUg-1 diet of BC228 was significantly higher than that of those fed control diet (P〈0.05).In addition,105 and 107 CFUg-1 diet of BC228 significantly enhanced lysozyme and phenoloxidase activities in the coelomic fluid of sea cucumber,respectively,in comparison with other diets (P 〈 0.01).Sea cucumbers,10 each diet,were challenged with Vibrio splendidus NB 13 after 45 days of feeding.It was found that the cumulative incidence and mortality of sea cucumber fed with BC228 containing diets were lower than those of animals fed control diet.Our findings evidenced that BC228 supplemented in diets improved the digestive enzyme activity of juvenile sea cucumber,stimulated its immune response and enhanced its resistance to the infection of V.splendidus. 相似文献

青少年的成长从某种意义上来讲就是"社会化"的过程,社会的矛盾冲突对青少年的成长影响巨大。本文从人的自然性与生存空间的去自然、家庭与社会、校园与社会、本土与全球等四个维度的时代性冲突入手,分析了社会化过程中青少年的心理与价值渴求。为了满足青少年社会化的心理与价值渴求,促进青少年健康的"社会化",笔者认为当代中学地理教育应进行变革,张扬如下教育价值与行动:亲近自然,促进生命健康完满的生命教育;走进自然与深入社会的实践教育;全球合作、国际理解基础上的民族主义教育。希望以此推动地理教育教学改革,深化地理教育的价值。 相似文献
