15.When many cells undergo necrosis at once, then definable patterns of necrosis are produced, depending upon the nature of the injury, the type of tissue, and the length of time. This is an example of coagulative necrosis. This is the typical pattern with ischemia and infarction (loss of blood supply and resultant tissue anoxia). Here, there is a wedge-shaped pale area of coagulative necrosis (infarction) in the renal cortex of the kidney.

15.大量细胞突然死亡可根据损伤的性质，组织的类型，作用的时间长短来分类。本例是凝固性坏死,是缺血坏死（血液供应减少导致组织缺氧）的典型方式。图示肾皮质苍白色的楔形坏死灶（梗死灶）。
