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/PAS染色，可抵抗淀粉酶消。

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.

该活检组织用淀粉酶；淀粉酶通常用于水解α-1抗胰蛋白酶，但由于α-1抗胰蛋白酶阻塞、隐藏于内质网中，淀粉酶触及不了，因此产生淀粉酶抵抗。
