The Effects Of Xanthine Analogs On Neonatal Rat And Adult Mouse Respiration, Susan M. Reynolds Jan 1987

The Effects Of Xanthine Analogs On Neonatal Rat And Adult Mouse Respiration, Susan M. Reynolds

Masters Theses

Apnea, a prolonged cessation of breathing, is commonly seen in premature infants. This condition, in its severest form, can be lethal and is a suspected cause of sudden infant death syndrome (SIDS). Sometimes referred to as apnea of prematurity, recurrent apnea is presently being treated with respiratory stimulants known as methylxanthines (MX) such as theophylline and caffeine. The benefits of MXs are accompanied by central nervous system stimulation and cardiostimulation which may be detrimental to a premature infant. Theophylline (1,3-diMX) has been shown to produce some of its effects by antagonizing endogenous adenosine. Another xanthine, enprofylline (3-propylxanthine), is presently being …


Cyanogenic Plants Of Illinois, Kevin E. Aikman Jan 1987

Cyanogenic Plants Of Illinois, Kevin E. Aikman

Masters Theses

Cyanogenesis in 50 species of vascular plants collected from east central Illinois was studied by examining 10 populations of each species. Each population consisted of 30 individuals, which gave an over all sample size of 300 plants per species. Herbarium specimens from the Stover Herbarium of Eastern Illinois University (EIU) were also tested for the presence of cyanide. More than 20,000 specimens were tested for this study which included cultivated plants, introduced weeds, and native plant species. The speed and degree of the HCN reaction as well as the specific plant part tested were included to give a more specific …
