Test 64 Flashcards
recognize and kill cells w/ DECREASED MHC class I Ag (virus/tumor infected cells)
NK cells
part of the heart that is adjacent to the esophagus
left atrium
*enlargement can compress esophagus and cause dysphagia
lies posterior to esophagus and LA
w/ TEE can dectect dissection/aneurysm
descending htoracic aorta
JVP tracing wave that is noticable in pts w/ afib
A wave (right atrial contraction)
calcification/thickening of pericardium > 4 mm
slowly progressive dyspnea
peripheral edema
ascites
constrictive pericarditis on CT
increases pancreatic bicarb secretion (CL content decreases in proportion to rise in bicarb)
Secretin (duodenal S cells) secrete secretein in response to RISE in H
RBF
RBF= (PAH clearance / (1-hematocrit))
EHEC
inadquately cooked hamburger meat> hemorrhagic colitis
like SHIGA toxin> inactivates 60S ribosomal subunit> inhibition of protein synthesis and eventual cell daeth
causes 80% of HUS in N.A.
EHEC
produce toxins that activated adenylate cyclase
B pertussis B. anthracis ETEC Campylobacter Bacillus V. cholerae
produces toxins that activate G. cyclase
ETEC
yersinia
compensatory response to low Hb, thrombocytopenia, absent hematopoietic cells in BM
aplastic anemia
EPO
Bioavailability
fraction of administered drug that reaches SYSTEMIC circulation
F= AUC oral dose X dose IV/ (AUC IVx odose oral)
stimulate follicular epidermal hyperproliferation and excessive sebum production and promote acne development in competitive atheletes

esmolol
you MAAE prefer to use these for asthma
isoproterenol
adrenergic agonist that STIMULATES B1 and B2
bronchodilation, increases HR and CO, decreases PAR
NOT used during acute MI
required for viridans to cause subacute bacterial endocarditis
preexisting valve damage that leads to local deposition of FIBRIN that is required for them to adhere
