20
Q

Probit is an abbreviation for the term

A

Probability integral transformation

21
Q

Permits a standard normal distribution of expected responses

A

Standard normal distribution

22
Q

A standard lethal normal distribution is?

It’s mean is also it’s?

A

Symmetric

True LD50 or median response

23
Q

Non responsive is observed at some dose and a response is observed at the next

24
Q

A log normal curve describing the range of tolerances to chemical

A

Standard deviation

25
Value related to the angle at which the dose response curve rises from the dose axis
Slope of the dose response curve
26
Slope of probit analysis
Straight line and slope is the reciprocal of standard deviation
27
Determines when a testing sequence terminates Relies on
Stopping rule Comparison of ratios
28
Intervals are commonly
0.4-0.6
29
What to do to know the effect of the year item in the organs
Organ in formalin ---> Histopathology to see cellular damage
30
Who reviews experimental researched What do they recommend
IACUC(Institutional Animal Care and Use Committee) OECD
31
What method is commonly used for chemicals
OECD
32
It is starting the dose according to the previous study
Sighting study
33
What does limit test mean
At 2000 mg/kg = no death= LD50
34
What method uses a lot and lesser animals
OECD: lesser Classical: alot
35
Aims of AOT
Signs of toxicity Establish LD50 Target organ toxicity
