-Yellow phosphorus = white+ Red
-Garlicky smell : Also seen in Celphos and arsenic poisoning
-Antidote : CuSO4 - BUT NOT TO BE USED ORALLY SINCE IT ITSELF IS A POISON
1) Phosphorus : MC
FOUND IN CRACKERS
7. Organophosphorus poisoning is characterised by all EXCEPT:

B Excessive sweating
D Fixed and dilated pupil
Ans. D Fixed and dilated pupil
8. All are features of Atropine poisoning EXCEPT:
A Dry skin
D Dry eye
Ans. B Miosis
Atropine poisoning involves Mydriasis not miosis
Atropine poison means Dhatura poisoning, the chief
signs & symptoms of Dhatura poisoning are-
Hot as a hare,
Blind as a bat,

Red as a beet,
Mad as a wet hen,
9.Q. Mucous membrane of stomach is dark-brown or black in poisoning due to:
A Sulphuric acid
B Nitric acid
C Oxalic acid
D Carbolic acid
Ans. A Sulphuric acid
Colour of mucosae in various corrosives-
1. Sulphuric acid = H2SO4 = Oil of vitriol; tongue swollen and
black or dark-brown.
2. Nitric acid (aqua fortis) - Xanthoproteic reaction-
yellow discolouration due to picric acid.
3. Carbolic Acid = Phenol.
a. Carbolism- white opaque eschar.
b. Carboluria= green urine.
-Oil of Vitriol
-Vitriolage : Throwing corrosive on another person
-MC symptom dur to ingestion : Pharyngeal Pain
-Brown discoloration of stomach
-Only local symptoms…no systemic effects
-Maximum chance of stomach perforation among all corrosives
-Mucosa will be burnt : Bloating Paper appearance
-Gastric lavage and alkali administration is contra indicated
-Antidote = MgO
-Only corrosive where gastric lavage can be done.
-Metabolites : Pyrocatechol
-Ochronosis : Hydroquinone deposits in cartilages.
-Carboluria : Both metabolites when excreted in urine gives Green colour
-Fatal dose : 1-2ml
-Fatal period: 3-4hrs
Mnemonic : 1-2-3-4
-Acid of Sugar/ Acid of Sorrel
-Presnt in Tomato/ Cabbage/ Spinach
-Oxalate reacts with calcium and thus causes Hypocalcemia
-Used as Ink remover
-Coffee ground vomiting: Blood + vomiting
-Antidote: Calcium Gluconate
Coffee ground vomiting
-Gives brown color to urine
-Xanthoproteic reaction : Skin becomes Yellow
-Mech. ; Dopamine/Serotonin/Nor epinephrine
-Derives from leaves of erythoxylum cocca
-Tactile hallucinations: also k/a Cocaine bugs/magnan bugs
-Paranoid delusions : is the fixed, false belief that one is being
harmed or persecuted by a particular person or group of people.
-If sniffed can cause Nasal septum perforation
-On oral intake : Black jet tongue
-Antidote = Amyl Nitrate
12. Both hepatic and renal failures can be caused by which of the following:
A Paracetamol toxicity
B Carbon tetrachloride
D Copper sulphate
E Silver nitrate
Ans. D Copper sulphate
PCM, CCl4, AgNO3 - liver failure.
As - kidney failure.
CuSO4- both hepatic & Renal failure.
CuSO4 even though poison is used as antidote for phosphorus poisoning
But not to be given orally as an antidote.
-Green line on gums
-Golden colour hairs
-Ptysalism : increase salivation
13. ‘Charas’ is:
A Leaves of Cannabis indica
B Flowers of Cannabis indica
C Stem of Cannabis indica
D Resin exudates of cannabis indica
17. Atropine is used for following EXCEPT:
A Organophosphorous poisoning
B Mushroom poisoning
C Physostigmine overdose
Atropine is contraindicated in Glaucoma and
indicated for the treatment of Organophosphorus poisoning,
Mushroom poisoning &
18. To preserve specimen, concentration of formalin used is:
Ans. C 10%
Specimens for pathological examination and Museums specimens
are preserved in 10% Formalin.
Formalin is ordinarily available as a 40% solution from the market,
it is diluted to 10% for use in preservation of specimens.
Formalin is never used to preserve toxicological specimens as it would
denature the poisons and make the estimation of poisons difficult.)
19. Most Specific test for Organophosphorus poisoning:
A Plasma cholinesterase
B RBC cholinesterase
C Acetylcholine at myoneural junction
-Donovan solution = Mercury + Arsenic
-MC mercuric salt causing poisoning is = HgCl2
Mu = Minimata Disease
Mmy = Mercuria Lentis
H = Hatter Shake
E = Erethism
A = Acrodynia
D = Danbury Tremors
- Blue-Black line on gums.
Minimata disease, is a neurological syndrome caused by severe mercury
Symptoms include ataxia, numbness in the hands and feet, general muscle
weakness, narrowing of the field of vision and damage to
hearing and speech.
-deposition of brown pigment on anterior lens capsule without affecting
- Brown malt reflex.
Tremor (Intentional, coarse, affecting arms, hands, tongue and later legs,
also called hatter's shake/glass blower's shake/danbury tremors)
Erethism : Psychological disturbance characterised by shyness, timidness,
loss of memory, depression, insomnia.
Acrodynia (Pink disease, characterised by pain, paraesthesia, pinkish
discolouration of hands and feets)
