Kev piav qhia
Walter Repp yog thawj zaug los ua ke PVP, ib qho kev xav acetylen derivative, hauv xyoo 1939. PVP tau siv rau hauv kev kho mob, tshuaj, tshuaj pleev ib ce, thiab kev lag luam tsim los ua cov ntshav plasma. Txawm hais tias tau txais kev pom zoo dav dav, kev tsis zoo tshwm sim tau raug tshaj tawm, tshwj xeeb tshaj yog thaum siv subcutaneously lossis hauv qab ntawm daim tawv nqaij, thiab thaum sib cuag nrog cov mucous membranes lossis cov kua dej hauv cov ntshav.
