局部贫血

Either of them predisposes the spleen to torsion.1 Acquired wandering spleen can also arise in multiparous women during pregnancy when ligamentous laxity occurs owing to hormonal changes.2 Chronic torsion can cause splenomegaly.

腹痛由脾脏包膜的收缩或局部腹膜炎引起。此外，尚可见贫血、白细胞计数增多，乳酸脱氢酶升高等。影像检查主要包括超声、CT、核素成像、血管造影。

In case 9, the heart is globally enlarged (Figure 11). This can result from, or be present in, many different conditions,43 such as endocardial fibroelastosis, fetal anemia,44 storage disorders, ischemia,45 infections,46,47 atrioventricular and semilunar valve regurgitation after tachycardia, and an atrioventricular block.

这个病例呈现为全心扩大（图11），这种情况可以是由多种疾病引发，也可存在于多种疾病中，比如心内膜纤维弹性组织增生、胎儿贫血、储存障碍、局部缺血、感染、心动过速引发的房室瓣和半月瓣反流以及房室传导阻滞。

There are 15 host pecies for haemaphysalis conicinna,among wich the investigated birds that are hikens,ducks,geese,pheasants,tomtits are all infected.Separately,the infection rates are 25.4%,12%,38%,100%,100%.However, those for the wild and penned animals are the highest.The ticks stick mainly on the head and facial areas,wattles,chests and abdominal areas and inner sides of the legs.The main harms are biting and blood sucking,leading to locational swelling,itching and infection,until severely causing aneamia and death.

结果显示，苍溪县嗜群血蜱流行面达97.4%，动物感染率7.7%-100%、在野外及农事活动的人群感染率53.8%；嗜群血蜱寄生宿主15种，其中被调查禽类的鸡、鸭、鹅、雉鸡、大山雀均受感染，感染率分别为25.4%、12%、38%、100%、100%，以野生和放养的动物感染率最高，主要寄生部位为头面部、冠髯、胸腹部及腿内侧，主要危害是叮咬吸血，导致局部肿胀、骚痒、发生感染，严重者引起贫血甚至死亡。

The dynamic changes of the number of T or B lymphocytes and the content of immunoglobulin G, IgM, IgA in peripheral blood, the number of CD〓, CD〓 lymphocyte subpopulation, T〓 cells and IgG, IgM, IgA antibody-producing cells, the ratios of CD〓 and CD〓 T cells in immune organs (thymus, bursa of Fabricius and spleen) and immune tissues (cecal tonsils and Harderian glands), the content of IgA, IgM, IgG in local fluid (tear, tracheal fluid, intestinal fluid and bile) of one-day chicks infected with chicken infectious anemia virus and CIAV-infected chicks immunized with Newcastle disease vaccine were determined respectively by immunohistochemistry, immunogold-silves and immunoenzyme staining in order to reveal mechanism of immunopathogenesis of chicks infected with CIAV and influence of immune responses of CIAV-infected chicks to ND vaccine.
