白細(xì)胞 Leukocyte

對于醫(yī)學(xué)生來說，進(jìn)行醫(yī)學(xué)英語學(xué)習(xí)是非常有必要的，因為在工作中會涉及到很多國內(nèi)外的最新醫(yī)學(xué)信息。下面是小編整理的白細(xì)胞 Leukocyte的資料，希望對你有所幫助！

白細(xì)胞 Leukocyte

　　白細(xì)胞

　　Or white blood cell (WBC); a colorless blood corpuscle capable of ameboid movement, whose chief function is to protect the body against microorganisms causing disease and which may be classified in two main groups: granular (granulocytes: basophils, eosinophils, neutrophils) and nongranular(nongranulocytes: lymphocytes, monocytes).

　　或稱白血球（WBC），為一能作變形運動的無色血細(xì)胞，其主要作用是保護(hù)機體抗御致病菌。它可以分為兩大類：粒性（粒性白細(xì)胞：嗜堿粒細(xì)胞、嗜酸粒細(xì)胞、嗜中性粒細(xì)胞）和非粒性（非粒性白細(xì)胞：淋巴細(xì)胞、單核細(xì)胞）。

　　The doctor counts the total number of white blood cells and works out how many different types of white blood cells the patient has. This is called the differential WBC count. form www.med66.com

　　醫(yī)生計算總白細(xì)胞數(shù)，并分析病人白細(xì)胞種類，這一過程稱為白細(xì)胞計數(shù)鑒別。

　　The number of white blood cells may go up and this may be because of a bacterial infection, bleeding or a burn. More rarely the cause of a raised white count is due to leukaemia, cancer or malaria.

　　白細(xì)胞數(shù)量上升的可能原因包括細(xì)菌感染、出血或燒傷，也有可能是因為白血病、癌癥或瘧疾，但較少見。

　　Low white counts can be a sign of bone marrow diseases or an enlarged spleen. Low WBC is also found in HIV infection in some cases. A person may lose white blood cells because they have autoimmune problems - this is where the antibodies that should fight diseases attack the body instead. Other reasons for loss of white blood cells include viral infections. More rarely, this can be a side effect of certain kinds of medication.

　　白細(xì)胞數(shù)低可能是骨髓疾病或脾腫大癥狀，有些HIV感染病人也會出現(xiàn)白細(xì)胞數(shù)降低的情況。自身免疫疾病，即本應(yīng)抗擊疾病的抗體反而攻擊機體，可導(dǎo)致白細(xì)胞丟失。其他可導(dǎo)致白細(xì)胞丟失的原因包括病毒感染，也可能是某些藥物副作用所到，但較少見。

　　WBC Ranges

　　白細(xì)胞范圍

　　Normal Adult Range: 3.8 - 10.8 thous/mcl

　　成人正常：3.8-10.8 ×109/L

　　Optimal Adult Reading: 7.3

　　成人最優(yōu)：7.3

　　Higher ranges are found in children, newborns and infants.

　　兒童、新生兒和嬰兒白細(xì)胞值較高。
