林宜平同志在《“实验性锡尘沉着症的初步观察”读后》(以下简称《读后》)一文中,向我们提出四个问题商榷。下面谈谈我们的看法。 一、关于锡尘有无致纤维化作用问题。《读后》的作者在文中曾四次提出了肯定的见解。如“我们认为作者们如果加大染尘量或重复给尘,同时延长实验时间,必然会发生纤维化”,“该文提到锡尘结节只到Ⅰ～Ⅱ级,是由于染尘量少,时间短,锡尘对组织的刺激作用较石英尘小,才发展到一定程度,纤维化不明显,但这绝不等于不导致纤维性变”,“相信只要加大给尘量,延长实验时间,锡尘结节的级别必然会增进的”,“我们认为:锡尘可以
Comrade Lin Yiping, in his article entitled “After Reading” (“Post-Reading”), a preliminary observation of experimental cadmium senescence, asked four questions for discussion. Let’s talk about our opinion First, on the tin dust caused by the role of fibrosis. The author of “Post-Reading” put forward affirmative opinions in the text four times. Such as “If we think the authors increase the amount of dust or dust to repeat, while extending the experimental time, will inevitably occur fibrosis,” “This article mentions tin dust nodules only to Ⅰ ~ Ⅱ level, is due to the amount of dust Less, less time, tin dust on tissue stimulation than the quartz dust is small, only to a certain extent, fibrosis is not obvious, but this does not mean does not lead to fibrous change ”,“ I believe as long as the increased dust to extend Experimental time, the level of tin dust nodules is bound to be enhanced, ”" We think: tin dust can
