白細胞

　　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胞，其主要作用是保護機體抗御致病菌。它可以分為兩大類：粒性（粒性白細胞：嗜堿粒細胞、嗜酸粒細胞、嗜中性粒細胞）和非粒性（非粒性白細胞：淋巴細胞、單核細胞）。

　　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 m.cddzsc.cn

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

　　白細胞數(shù)量上升的可能原因包括細菌感染、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)白細胞數(shù)降低的情況。自身免疫疾病，即本應抗擊疾病的抗體反而攻擊機體，可導致白細胞丟失。其他可導致白細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。 醫(yī) 學教 育網(wǎng)搜集
