鲤、鲢和草鱼的嗜中性白细胞在体外条件下对酵母细胞的吞噬百分率随环境温度升高而上升．在１０℃以上，三种鱼嗜中性白细胞的吞噬百分率可达９０％以上，其中鲤鱼的吞噬作用最强，其次是鲢鱼和草鱼．另外酵母细胞被吞噬吸收的比例随温度升高而逐渐增加  相似文献   

中国对虾血细胞吞噬活动中超氧阴离子（O↓（2）↑（-））的产生   总被引：11，自引：0，他引：11  

王宝杰  王雷 《中国水产科学》2003,10(1):14-18

用Zymosan A对中国对虾（Penaeus chinensis）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O2^-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O2^-的产生;不同浓度的Zymosan A对血细胞产生O2^-的影响不同。Zymosan A在0.25-1.0mg/ml对随质量浓度的增加,产生O2^-的量也增加,但当Zymosan A质量浓度继续增加到1.5和2.0mg/mL时,产生O2^-的量反而下降。用同一浓度的Zymosan A对不同密度血细胞进行刺激产生O2^-的强度也不同,随着密度的增加,血细胞产生O2^-的量增加。SOD、NEM和碘代乙酰胺（Iodoacetamide）对血细胞吞噬过程中O2^-的产生有抑制作用;Hg^2 、Cr^3 、Pb^2 、Cu^2 和Zn^2 5种重金属离子也能抑制血细胞产生O2^-;不同个体的中国对虾血细胞产生O2^-的能力不同。NBT还原法测定中国对虾血细胞吞噬时产生的O2^-可以作为检测对虾免疫状态的指标。  相似文献

A biologically active IL-1β derived peptide stimulates phagocytosis and bactericidal activity in rainbow trout, Oncorhynchus mykiss (Walbaum), head kidney leucocytes in vitro     

S Peddie  J Zou  & C J Secombes 《Journal of fish diseases》2002,25(6):351-360

The present work provides the first information concerning the ability of a rainbow trout interleukin-1β (IL-1β) derived peptide, P3, to enhance phagocytosis and bactericidal activity. P3 was synthesized to complex with the IL-1 receptor and corresponds to fragment 197–206 (YRRNTGVDIS) of the trout sequence. A dose-dependent effect of P3 on phagocytosis in head kidney leucocytes was documented, with an optimal response occurring at 0.25 m M . With respect to the temporal kinetics of P3 induced activation, an incubation period of 2 h resulted in enhanced phagocytic activity, although incubation times of between 4 and 24 h were optimal. An additive effect was observed when P3 (0.1 m M ) was combined with another IL-1 derived peptide, P1 (0.1 m M ). The latter peptide corresponds to fragment 146–157 (YVTPVPIETEAR) and is equivalent to a region in the mammalian protein that is known to be part of the receptor binding domain, but does not overlap with P3. With respect to bactericidal activity, macrophages incubated for 24 h with 0.1 m M P3 demonstrated an enhanced ability to kill an avirulent strain (MT004) of the Gram-negative salmonid pathogen Aeromonas salmonicida . Further investigation revealed that extracellular production of superoxide anions was not responsible for the enhanced bactericidal activity of macrophages exposed to P3.  相似文献

Effect of Dietary Lipids on Macrophage Function,Stress Susceptibility and Disease Esistance in Atlantic Salmon (<Emphasis Type="Italic">Salmo salar</Emphasis>)     

T.?Gj?enEmail author  A.?Obach  C.?R?sj?  B.G.?Helland  G.?Rosenlund  E.?Hvattum  B.?Ruyter 《Fish physiology and biochemistry》2004,30(2):149-161

As the supply of marine fish oil is becoming a limiting factor in the production of Atlantic salmon (Salmo salar), new diets and alternative sources of energy are being tested. Plant oils are natural potential candidates to replace fish oil, but the different levels of essential polyunsaturated fatty acids may influence the health and growth of salmon. In this study, we have investigated the resistance to transport stress and bacterial infection, phagocytic activity in head kidney macrophages and eicosanoid metabolism in salmon fed three different diets. In high-energy fishmeal based diets, 50% and 100% of the supplementary fish oil (FO) was replaced with soybean oil (SO). The three dietary groups were fed for 950 day-degrees at 5 °C (27 weeks) and 12 °C (11 weeks) before challenging the fish with Aeromonas salmonicida, analyzing the lipid composition of head kidney and examining macrophage function in vivo and in vitro. Dietary fatty acids affected the lipid composition of the kidney. The level of eicosanoid precursor’s 20:4n-6 and 20:3n-6 were 3 and 7-fold higher in the 100% SO group compared with the FO group. The total fraction of n-3 lipids in kidney was 19% in the SO group, compared to 16% and 12% in the 50% or 100% SO groups, respectively. However, the production of leucotriene B₄ (LTB) and prostaglandin E₂ (PGE) immunoreactive materiel from exogenously added arachidonic acid in head kidney macrophages was only affected by the composite diet (increased) at 5 °C. In addition, the phagocytic activity of kidney macrophages in vivo and in vitro was not affected by diet. No effect of diet was observed on transport stress or susceptibility to a bacterial infection with Aeromonas salmonicida. Atlantic salmon therefore seems to tolerate a diet solely based on soybean oil as lipid source, without any detrimental effects on growth, health and immune functions.  相似文献   

中华绒螯蟹血细胞体外吞噬能力的研究     

刘凯  陆宏达 《南方水产》2007,3(6):47-51

通过体外制备血细胞单层的方法,研究了中华绒螯蟹(Eriocheir sinensis)血细胞对蜡状芽孢杆菌(Bacil-luscereus)及鼠红细胞的吞噬能力,并探讨了血清孵育对血细胞吞噬能力的影响。结果表明,以vanHARREV-ALD氏液配制的浓度为100.0mg·mL-1的L-cysteine溶液可以作为中华绒螯蟹血淋巴的抗凝剂,中华绒螯蟹血细胞在20℃下培养1h的存活率可维持在(92.5±0.9)%。中华绒螯蟹血细胞贴壁后呈扁平状,胞质可沿玻片表面迅速伸展并伸出类似于伪足的原生质突起,具有吞噬能力,对蜡状芽胞杆菌吞噬率为(5.1±1.4)%,不能吞噬鼠红细胞,血清孵育不能增强中华绒螯蟹血细胞的吞噬能力。  相似文献

不同育龄三角帆蚌血细胞吞噬率和血浆抗菌活力的比较     

许巧情  郝立平 《大连水产学院学报》2011,26(5):442-445

以2～5育龄三角帆蚌Hyriopsis cumingii为对象,研究了三角帆蚌血浆对大肠杆菌、金黄色葡萄球菌、溶壁微球菌、嗜水气单胞菌的抗菌活力和血细胞对金黄色葡萄球菌的吞噬率。结果表明：4种育龄的育珠蚌血浆对金黄色葡萄球菌的抗菌活力最强,其次为溶壁微球菌、大肠杆菌和嗜水气单胞菌,其中3龄育珠蚌对4种细菌的抗菌活力最强;4龄育珠蚌对金黄色葡萄球菌的吞噬率最高,达到36.6%,吞噬指数达到3.75,其次为5龄育珠蚌,2龄育珠蚌对金黄色葡萄球菌的吞噬率最低,仅为25.2%,吞噬指数为2.95。本研究结果证实：在2～5育龄内,3～4育龄的三角帆蚌育珠蚌的吞噬率和抗菌活力最强,抵抗外来病原菌的能力最高;但随着育珠年龄的增长,三角帆蚌免疫能力不断下降,因而养蚌育珠过程中要加强对高龄蚌抗病防病能力的管理。  相似文献
