脾脏是动物机体内放射敏感性最高的器官之一。它的损伤以及因而引起的继发反应在放射病的发生发展中起着重要作用。许多实验曾经证明,受全身绝对致死剂量的X-射线照射而遮护脾脏的动物,其造血组织的破坏较轻、复生较快,且动物的存活率也明显提高。给受照机体植入脾脏或注射脾脏匀浆也能达到同样效果。脾脏在全身电离辐射后的改变,形态学方面已经累积了不少资料。多数实验表 Spleen is one of the most radiosensitive organs in the animal body. Its damage and the resulting secondary reactions play an important role in the development of radiation sickness. Many experiments have shown that animals spleens spleen exposed to whole-body absolute lethal doses of X-rays have less damage to hematopoietic tissues, faster regeneration, and significantly improved animal survival rates. To the irradiated body spleen injection or spleen homogenate injection can achieve the same effect. Spleen after systemic ionizing radiation changes, morphology has accumulated a lot of information.
