▦ Physiologic Action of Gut Hormones
Criteria
① Peptide must be related into blood during time that a biologic response in a target organ is being stimulated or inhibited
② IV infusion of pure natural peptide must reproduce the effect on target organ
③ Synthetic peptide should reproduce the effect found with natural peptide
④ Circulating concentration of peptide that cause stimulat
Laboratory Monitoring of Patients with HIV Infection
Patients with CD4+ T cell counts <200/L are at high risk of disease from P. jiroveci, while patients with CD4+ T cell counts <50/L are at high risk of disease from CMV, mycobacteria of the M. avium complex (MAC), and/or T. gondii. Patients with HIV infection should have CD4+ T cell measurements performed at the time of diagnosis and every 3&
