|METHYLXANTHINES(Theophyline,caffene,Theobromide,Aminophylline)||PHOSPHODIESTERASE inhibition; prevents degradation of cyclic AMP to 5′- AMP; increases cAMP|
|ATROPINE||BLOCKS cholinergic-induced bronchospasm,bronchodilatory action|
|TERBUTALINE||B2 agonist stimlation during a bronchospasm|
|Relate the utility of cromolyn for the treatment of asthma.||non-steriodal medication (anti-inflammatory) can reduce the need for quick relivers and reduce bronchial hyperrespnsiveness. also can improve morning peak flow and decrease symptoms of nocturnal asthma|
|Describe the make-up of methemoglobin?||Ferrous ion (Fe2+) in the heme portion of hemoglobin becomes oxidized to the ferric state (Fe3+);tyrosine substitutes histidine in either A or B chain in the Globin protion of the hemeglobin molecule. tyrosine causes ferrous ion to oxidize to ferric state|
|How does mehemoglobin affect tissue oxygenation?||I|
|Oxygen attachment on hemoglobin?||Pyrrole Ferrous ion(heme portion)|
|Attachment od CO2 on hemoglobin?||Teminal Amine group Globin portion|
|Attachment of H+ on hemoglobin?||imidazole group on deoxygenated hemoglobin|
|Discuss how coperativity enhances the binding of oxygen to hemoglobin at the lungs and how it facilitates the release of oxygen to the cells at the tissues?||Cooperativity ehances bonding of oxygen by increasing bonding potentional. Conversely, at the tissue level the unloading of oxygen molecule facilitates the release at oxygen at the other sited|
|4 factors that inflence oxygen- hemoglobin affinity?||body temp. , PaCO2, Arterial pH, 2-3-DPG|
|Define Bohr Effect:||Effect of Carbon Dioxide or (H+) pn uptake and relase of oxygen from the hemoglobin(effect mild)|
|Define Haldane Effect:||influence of CO2 binding and unbinding on the release and uptake of oxygen , respectively, by the hemoglobin molecule|
