ExaminationofaMammalianBloodSmear
Examination of a Mammalian Blood SmearThe distribution and appearance of the formed elements of blood can tell a great deal about the condition of the donor. Disproportionate numbers of white cells (leukocytes) and/or the presence of immature leukocytes are indications of a serious disease, as are high or low platelet counts or misshapen red blood cells. The presence of a high proportion of eosinophils (see figure be......阅读全文

Blood：凝血机制新发现
科学家们发现多聚磷酸盐在凝血过程中参与了多个阶段，并且涉及了静脉/动脉堵塞(血栓形成)和炎症反应。Illinois大学的研究人员用一些小分子阻断多聚磷酸盐的活性，成功缓解了动物模型的动静脉血栓和炎症症状，提出这类分子可用于血栓治疗。目前市面上的血栓治疗药物会引发出血，而这项研究将有助于大大减少这
