Gulu la United States Pharmacopeia la zida zachipatala ndi 6, kuyambira USP kalasi I mpaka USP kalasi VI, ndi USP class VI kukhala giredi yapamwamba kwambiri.Mogwirizana ndi USP-NF General Rules, mapulasitiki oyesedwa mu vivo biological reaction adzaperekedwa ku gulu lapulasitiki lachipatala.Cholinga cha kuyesaku ndikuzindikira biocompatibility ya mapulasitiki kuti agwiritsidwe ntchito pazida zamankhwala, ma implants, ndi machitidwe ena.

Chaputala 88 cha USP Class VI chikunena za kuyesa kwa mu vivo bioreactivity, komwe cholinga chake ndi kudziwa zotsatira za bioreactivity ya zinthu zotanuka pa nyama zamoyo.Ma feedstock acell fakitaleimaphatikizapo zofunikira zitatu zoyesera: 1. Mayeso a jekeseni wadongosolo: Chitsanzo cha mankhwalawa chimakonzedwa ndi chotsitsa china (mwachitsanzo, mafuta a masamba), ndipo polyethylene glycol imagwiritsidwa ntchito pakhungu, kutulutsa mpweya, kapena pakamwa.Mayesowa amayesa kawopsedwe ndi kuyabwa.2. Kuyesa kwa intradermal: Chitsanzo cha pawiri chimawonetsedwa ndi minofu yamoyo ya subcutaneous (minofu yomwe chipangizo chachipatala / chipangizo chikukonzekera kukhudza).Kuyesaku kuyeza kawopsedwe komanso kupsa mtima kwanuko.3. Kuyika: Chosakanizacho chimayikidwa mu minofu ya chitsanzo.Kuyeza kumayesa virulence, matenda ndi kuyabwa.
