in this research at the first, xylometazoline hydrochloride drug (xy) and its fullerene connected form (fxy) were optimized. natural bond orbital (nbo) calculations for these compounds were carried out at the b3lyp/6-31g* quantum chemistry level, in the gas phase and the liquid phase. these calculations can be performed at different accuracy levels depending on the aim of the theoretical study....

Objective: The objective of this study was to evaluate the effectiveness of firbreoptic intubation in patients with anticipated difficult airway. Methods: Forty patients of both sexes were included in the study. The patients were informed about the procedure in the preoperative visit. After one mg of midazolam and 0.2 mg of glycopyrrolate, local anesthesia of the upper airway, nasal cavity and ...

for analyzing of compositions molecular orbitals in this article in order to combination only- xylometazolin-c7 x2 (xy) and c60– xylometozolin-c65-x2 (fxy), first got energies of highest occupied molecular orbital (homo) and lowest unoccupied molecular orbital (lumo) by using nbo analyze in gaussian 03 software. then, occupancy parameter, gap of energy, and δnmax were calculated   by support of...

Abstract Background A simple, robust, precise, and an accurate HPLC method was established for simultaneous estimation of xylometazoline hydrochloride ipratropium bromide from a nasal spray dosage form. The effective separation obtained by injecting 10 μl sample standard solutions on to Inertsil ODS column, 250 × 4.6, mm, 5 μ at 45 °C using phosphate buffer with 1-pentane sulphonic acid sodium ...

Abstract Introduction Treatment of Eustachian tube dysfunction has remained an enigma for a long time. Balloon tuboplasty, even though effective, is not considered by many, as it invasive, expensive, and cumbersome. Hence, we tried to find some simple inexpensive solution the same in chronic otitis media. In this background, evaluated use barotubometer treat obstructive mucosal Materials Method...
