Correct Answer -C

ED50 refers to Effective Dose of a drug needed to produce a particular response in 50%
of population. It is a quantitative measure of the potency of a drug. Smaller the ED50 value,
more potent is the drug

Answer -C
Ans. is 'c' i.e., Cytoplasmic vacuole
o Fatty changes occur in alcoholic steatosis (fatty liver). It is
manifested by appearence of lipid vacuole in the cytoplasm, which is
a sign of reversible injury.

Correct Answer - A
Ans. is 'a' i.e., Apaf 1
One of these proteins is cytochrome c, well known for its role in
mitochondrial respiration. In the cytosol, cytochrome C binds to a
protein called Apaf-1 (apoptosis activating factor-1), and the
complex activates caspase-9. (Bc1-2 and Bcl-x may also directly
inhibit Apaf-1 activation, and their loss from cells may permit
activation of Apaf-1

Correct Answer - A
Ans. is 'a' i.e., Coagulative necrosis
Coagulative necrosis
* This is most common type of necrosis.
* This type of necrosis is most frequently caused by sudden
cessation of blood flow (ischemia) in organs such as heart (MI),
Kidney (ATN), adrenal gland, and spleen.
Note: Brain is the only exception, i.e.,. It is the only solid organ in
which ischemia leads to liquifactive necrosis not coagulative
necrosis.
* It is also seen with other types of injury e.g.,liver necrosis in viral
hepatitis, Coagulative necrosis of skin after burns (Thermal injury).
Why there is predominant protein denaturation and no enzymatic
digestion ?
Hypoxia causes intracellular acidosis (has been explained earlier)
> .t pH results in denaturation ofproteins which includes not only
structural proteins hut also enzymes
So, there is no enzymatic digestion. o The necrotic cells retain their
cellular outline for several days.
Liquefactive necrosis
* It is the necrotic degradation of tissue that rapidly
undergo softening and liquefaction
