So we say that they'd be Periodic acid and schiff positive, or PAS positive, as well as diastase resistant.

因此诊断依据为过碘酸-希夫染色阳性/PAS染色阳性，并可抵抗淀。

The tissue is also exposed to diastase, which is an enzyme that normally destroys alpha-1 antitrypsin, but since alpha-1 antitrypsin's stuck and hidden away in the endoplasmic reticulum, diastase can't get to it and so it's diastase resistant.

活检组织也被施用淀；淀通常用于水解α-1抗胰蛋白，但由于α-1抗胰蛋白阻塞、隐藏于内质网中，淀触及不了，因此产生淀抵抗。
