44
Q

This refers to cases of short and extreme violence that may include symptoms of chronic poisoning.

A

Sub-Acute Poisoning

45
Q

This refers to kind of poisoning in which there is gradual deterioration of function of tissues and may or may not result in death.

A

Chronic Poisoning

46
Q

This refers to those in which the poison was taken without intention to cause death. It may be taken by mistake or without knowing that it is poison.

A
