    Modification of chitosan films as a way of their transport properties regulation
    (Publishing House of Lviv Polytechnic National University, 2012) Murzagildina, Angela; Kulish, Elena; Kuzina, Lyudmila; Mudarisova, Roza; Kolesov, Sergei; Zaikov, Gennady
    Chitosan films obtained from solutions in acetic acid and containing the antibiotics – cephazolin and cephotoxim – have been investigated and the principal possibility of regulating their transport properties as regards the medicinal preparations release has been demonstrated. This regulation can be carried out by films thermal modification consisting in heating of the formed films at the temperature of about 393 K and their treatment with sodium dodecylsulphate solution. Досліджено плівки хітозану, отримані з розчинів в оцтовій кислоті, і які містять антибіотики – цефазолін і цефатоксим. Показана принципова можливість регулювання їх транспортних властивостей стосовно виходу лікарських препаратів. Встановлено, що регулювання здійснюється термічним модифікуванням плівок, а саме прогріванням сформованих плівок за температури близькій до 393 K і їх обробленням поверхнево-активною речовиною – додецилсульфатомнатрію.
