Q

RADIOPROTECTORS

A
  • cellular rsponse to XRT
83
Q

when are cells most senitive to XRT in the cell cycle

A

G2 and M phase, mid sensitivity in G1, most resistant in S phase

84
Q

when is the most resistant timed in the cell cycle

A

S phase

85
Q

regeneration after EBRT damage organs

A

some organs can be fixed by regeneration
Organs that are repaired this way are made of VIM (vegetative intermitotic) or DIM cells ( differentiating intermitotic)
these organs are: skin, sm intestine, BM

86
Q

rpair after XRT damage

A

is healed by cells of a different organ/ cell type- this causes fibrosis or scar formation

87
Q

what dose is repair most common at

A

doses >1000CGY

88
Q

What organs is repairf most common in

A

radioresistant organs RPM and FPM parenchymal cells that do not divide or have the abiloty to divide (RPM -reverting postmitotic cells ex: liver or FPM- fixed postmitotic cells ex: nerve, muscle, RBC, sperm

89
Q

structually defined FSU and ex

A

when only a predtermined amount of the organ can e replaired

ex: kidney and SC

90
Q

Structurally undefined FSU and ex

A

skin, where cells can migrate through organ and repair damage

91
Q

the 3 acute radiation syndromes as a resultg of whole body exposure

A

hematopoetic syndrome
GI syndrome
cerebrovasculat syndrome

92
Q

what are the phases of the whole body exposure syndrome

A

prodomal stage
latent phase
manifest illness stage

93
Q

who is more resistant to XRT? M vs F old vs young

A

F are more resistant

extremely young and old are more sensitive than mid aged

94
Q

dose and mean dose of hematopoetic syndrome

A

100-1000cGy

mean dose” 350-450cgy

95
Q

hematopoetic syndrome phases s&s and timing

A

latent stage lasts from few days to 3 wks (BM and SCdie)
msnifest illness week 3-5 pancytopenia occurs
<300 pt will survive
300-500 death can occur after 4 wks
500-1000 death can occur in 2 wks

96
Q

COD hemapoetic syndrome

A

infection and hemorhage after BM destruction

97
Q

what dose to GI syndromed occur`

A

1000-10,000cgy

can overlap hematopoetic syndrome at doses as low as 600cgy and with cerebrovascualr syndrome >5000

98
Q

mean survival time gi syndrome

A

3-10 days and as long as 2 wks

99
Q

GI syndrome timing and s&s

A

prodormal hrs after exposure- n&v, darhea and abdo cramps
latent stage2 - 5 days after exposure
manifest illness stage 5-10 days post exposure : n&v, diarrhea and fever

100
Q

COD GI syndrome

A

BM damage leads to infection, dehydration, and electrolyted imbalance

101
Q

what blood level changes occur in GI syndrome

A

-WBC leukocytes

other blood levels dont get a chance to change as pt dies b4 this happens

102
Q

dose for cerebrovascualr damage

A

can occur at doses as low as 5000cgy ->10,000CGY

103
Q

Stages and timing and s&s of cerebrovasular syndrome

A

prodomal stage mins-hrs (nervousness, confusion, n&V, loss of conciousness and burning sensation
latent stage- several hours or less
manifest illness-5-6 hous after exposure diarhea, convulsions, coma and death`

104
Q

what is COD from Cerebrovascular syndrome

mental retardation and microencephaly

108
Q

what occurs during fetal XRT after 20 weeks gestation

A

functional defects like sterility

109
Q

what does stochastic effects mean

A

severity of cancer does nOT depend on dose given, every dose causes some level of risk

110
Q

deterministic effects

A

after a certain dose threshold is exceeded an effect will happen, below this dose the effect will not ocur

2.5-3

116
Q

stochastic vs deterministic in terms of timing

A

deterministic are changes seen within days-weeks

stochastic are effecst seen months- yrs after xposure

117
Q

reference dose of alpha in BED equation

A

alpha denotes the dose for early effects and is 10Gy

118
Q

reference dose beta in BED equations

A

beta denots the dose for late effects and is 3Gy
