酞酸钾纤维是一种有优良物理、化学特性的单结晶纤维,可作整形强化材料、摩擦材料等多方面使用的新的原材料。纤维形状为直径0.2～0.5μm、长10～20μm的针状结晶、类似石棉。其对机体的影响尚完全不清楚。本实验从大鼠肺、腹腔及背部皮下给予酞酸钾后,研究这些部位出现的组织学变化 [方法]:被检动物为Fischer344/jcl雌性大鼠,钛酸钾(K_2D,TiO_2)直径0.2～0.5μm,长10～20μm,用20mg/0.5ml混
Potassium phthalate fiber is a single crystalline fiber with excellent physical and chemical properties. It can be used as a new raw material for many aspects such as plastic strengthening materials and friction materials. Fiber shape of 0.2 ~ 0.5μm in diameter, length 10 ~ 20μm needle-like crystals, similar to asbestos. Its impact on the body is still not clear. In this experiment, the histological changes in these sites were studied after subcutaneous administration of potassium phthalate to the lungs, abdomen and back of rats. [Methods] The animals were tested for Fischer344 / jcl female rats, potassium titanate (K 2 D, TiO 2) 0.2 ~ 0.5μm, length 10 ~ 20μm, mixed with 20mg / 0.5ml
