In this study, zinc oxide nanostructures (ZnO NS) were synthesized using Pyrus pyrifolia fruit extract. Biophysical characterization results confirmed that the materials are crystalline wurtzite ZnO structures. Field emission scanning electron microscopy (FESEM) revealed NS cubical, and sizes range 20–80 nm. Transmission (TEM) XRD a crystal lattice spacing of 0.23 nm (101) plane on NS. UV-Visib...

This study investigated the expectorant effects of immature Asian pear extract (IAP; Pyrus pyrifolia Nakai) on subacute pulmonary injuries in Balb/c mice induced by particulate matter with a diameter approximately 2.5 μm (PM2.5). IAP was administered at three doses, namely, 400, 200, and 100 mg/kg. The body weight gain changes, lung weights, surface gross inspections, tracheal secretions, subst...
