IN CHRONIC ARSENIC POISONING--

greatest amount of this element will be found in-------
1)kidney
2)liver
3)keratin tissue
4)bone marrow
5)brain

[doubt is probably between (2) ,(3) & (4) BUT if only one is to mark,then which will be best option????]


IF IT WAS 'ACUTE AS-POISONING'--then among the same options which will be the choice????

it max in liver in acute and bone marrow in chronic i believe.............will wait for a person to talk with ref, its a repeat qn..........some one can see the original and quote the answer given pl........

in chronic intoxication greater amounts found in liver.muscles for next few days then skin,hair nail and keratin tissues.bt greatest amt no doubt is liver.reference parikhs 6th edition page 9.10.in acute intoxication the features of git predominate .burning of lips and difficult swallowing r the features.acute can be diagnosed by urinary levells wich r greater than 200 in chronic intoxication muscle aches,garlic odour and numbness seen.bt no git involvement

acc to parikh, pg 9.13 section 9.06-
after ingestion and absorption greatest quantity is found in liver but if the patient survives arsenic starts getting deposited in muscles then bones and finally in chronic poisoning( months) in keratin tissues like hair, nail and skin.. liver shows fatty changes by that time..thats why in chronic cases we send hair samples and not liver biopsy..
so, i think the best ans would be- keratin tissue.
if its acute poisoning then liver..

i was also of same opinion as drspawar,but 'ACROSS-FSM' has given the just opposite answers to these...

need mpge-expert opinion to confirm which view should be followed...
