Theses and Dissertations
This dissertation project aimed to demonstrate that pulmonary delivery of two anorectic gut secreted peptides, peptide YY (PYY) and oxyntomodulin (OXM) enabled food intake suppression and reduced body weight gain in rats via their systemic absorption from the lung and interaction with the brain. After PYY and OXM were administered to the lungs at varying doses, food intake and body weight gain were monitored in freely feeding rats. Significant 30-35 % food intake suppression was achieved for 4-6 h following pulmonary administration of endogenously active PYY3-36 and OXM1-37 at 0.80 and 0.50 mg/kg, respectively. Moreover, when administered daily for 7 …
