嗜鹼性粒細胞(basophil)和嗜酸性粒細胞(eosinophil)的區別
讓我們先簡單地看一下血液的成分，以便清楚地瞭解嗜鹼性粒細胞和嗜酸性粒細胞的區別。血液主要由白細胞、紅細胞、血小板和血漿組成。血漿是血液的液體部分，佔血液體積的一半以上。白細胞約佔整個血容量的1%，紅細胞約佔45%。白細胞或白細胞分為有顆粒或無顆粒的細胞。顆粒白細胞包括中性粒細胞、嗜酸性粒細胞和嗜鹼性粒細胞，非顆粒白細胞包括淋巴細胞和單核細胞。嗜鹼性粒細胞和嗜酸性粒細胞之間的關鍵區別在於嗜鹼性粒細胞可以通過釋放肝素、組胺和血清素來**炎症反應，而嗜酸性粒細胞則通過吞噬作用和產生抗組胺藥來對抗寄生蟲。
什麼是嗜鹼性粒細胞(basophil)？
Basophils are granular leukocytes with an S-shaped multi-lobed nucleus and are similar to the size of eosinophils. These cells stimulate inflammation resp***es by releasing heparin, histamine, and serotonin. Biologists believe that basophils are produced and matured in the bone marrow. Certain morphological and functional features of basophils are equal to mast cells, which are common in tissues. Basophils are hardly seen in the blood of healthy humans, because once they release, they circulate for a few hours in the blood and migrate to the tissues where they last a few days. Basophils have relatively few granules, which are water soluble. Therefore, identifying basophils in blood is quite difficult. However, when basic stains are used to identify, the cytopla** of the basophils stain blue in color.
什麼是嗜酸性粒細胞(eosinophil)？
Eosinophils are bone marrow derived granular leukocytes with two-lobed nucleus. They provide an important defense against parasites by phagocytosis and produce antihistamines. When acid stains are used, the cytopla** of the eosinophil stains in red. Usually, 1% to 5% of white blood cells are eosinophils. Very low number of eosinophils are found in the blood circulation of healthy pers*** because these cells are primarily tissue-dwelling cells.
