Respiratory Effects Of 1-Propylxanthine On Neonatal Rats, Amanda Hance
Student Honors Theses
Neonatal apnea is commonly treated by methylxanthines like caffeine or theophylline, but these drugs have the potential to create serious side effects. As an alternative, a new xanthine analog, 1-propylxanthine (1-PX), was recently synthesized at Eastern Illinois University. The respiratory effects of 1-PX were investigated in 4- to 7-day-old rats to determine if 1-PX could be a respiratory stimulant. Each rat was placed in a heated body plethysmograph, and its respiratory rate and volume were measured using a flow transducer, pneumotachograph, and Power Lab data acquisition system. After a 10-min control period, the rat was given a s.c. dose of …
