Piracetam Hydrazide yog dab tsi?
Lub mechanism ntawm kev ua ntawmPiracetam Hydrazidefeem ntau yog raws li nws cov khoom tshwj xeeb ntawm lub cev thiab tshuaj lom neeg. It has extremely low surface tension, and can spread quickly on the surface of tears to form a uniform and stable anti-evaporation film, effectively preventing water evaporation and maintaining the stability of tear film. Nyob rau tib lub sijhawm, nws cov permeability zoo ua rau nws nkag mus rau hauv meibomian caj pas duct, yaj thiab dredge lub blocked denatured daim tawv muag roj, thiab txhawb kev noj qab haus huv daim tawv muag cov roj secretion. Tsis tas li ntawd, cov yeeb yaj kiab tsim muaj cov pa oxygen siab - nqa lub peev xwm, uas tuaj yeem muab cov pa oxygen txaus rau pob kws. Nyob rau tib lub sijhawm, nws cov dej -dawb thiab preservative- cov yam ntxwv dawb tsis txhob muaj kev txhawb nqa ntxiv, tsim kom muaj qhov chaw zoo rau qhov muag ntawm qhov muag thiab pab txhawb kev kho cov pob txha epithelium.
