PRESERVE due to intact LV contractility
what will you see ina coronary angio w/ someone who has Vasospasm(printzmal angina)
NO OBSTRUCTIVE lesions. vasospam is due to hyperractivity of vascular SM
what are two ways to cause apoptosis
ubiquitton proteosome/ Aphagy(vaculoes made w/in a cell
what’s the most common cause of budd chiari
PCV due to increase in viscosity
Hypoxemia
low partial pressure of O2 in blood(PaO2 <60 & SaO2 <90
FiO2-PAO2-PaO2-SaO2 What can effect each
FiO2 (high alt not enough O2)
PAO2( n-ething that increase PACO2(COPD, HYPOVENT)
what is the purpose of PAO2
the pressure to sqz blood across capillaries to PaO2
what can effect PaO2
if the capillaries in the alveolar air sac are thickened (interstitial fibrosis of lung
what’s the role of Hb
to carry O2 to tissues
what is Anemia
decrease in RBC MASS so PaO2/SaO2=NORMAL
what is methemoglobenia
Iron oxidized to Fe+3
caused by oxidant stressors(sulfa nitrate)
What’s PAO2/SaO2 in methehemoglobenia
PAO2=NORMAL
SaO2= DECREASE less Fe+2 around to bind trt: w/methylene blue bring bk to Fe+2
what happens to PT/PTT/BT/PLT count in HUS
PT/PTT=Normal BT=increase PLT=decrease
What’s Serum Ca+2/uric acid, Urine Ca+2, pH, Cystine in Ca+2 oxalate stones
Serum Ca+2/ Uric acid=NORMAL
URINE Ca+2=Increase
URINE pH= decrease
Urine Cystine=NORMAL
What’s Serum Ca+2/uric acid, Urine Ca+2, pH, Cystine in Ca+2 phosphate stones
Serum Ca+2= INCREASE Uric acid=INCREASE
URINE Ca+2=Increase
URINE pH= INCREASE
Urine Cystine=NORMAL
what will you see in histo for lactase def
Normal epi( tall vili w/ focal collections of goblet cells crypts of lieberkuhn) simple columnar epi
Duod epi w/ dense staining of chromagin A describe what GI porblem
IBS

N-acetyl-p-benzoquinoeimine(NAPQI) build up
what’s the most common twin prego
Monochorionic-diamniotic (cleaves day 4-8)monozygotic
what is monochorionic
a shared placenta(increase risk for twin twin tranfusion syndrome
what is diamniotic
2 sacs
DOC for parkinsonian like symptoms
Benztropine/trihexyphnidyl(anti-musc) for ELDERLY amantadine(increase dopa)
what’s the lab for hyperosmolar hyperglycemic state

osmolality >320
Na+ low HCO3>18
what is transformation/what bacteria can do it
bacteria tk up naked DNA from lysis bacteria & mk it there own & express new genes. (s.pneumo, H.influ b, Neisseria
what kind of mutation do you see in achandroplasia
gain of FX of the fibroblas growth facto receptor 3 gene
restrictive myopathy can cause what type of heart problem
DIALATED CARDIOMYOPATHY due to thransthyretin misfolding & producing amyloid in the heart
