As the haemozoin is responsible for the chill and the high fever for reccuring its every 3 to 4 days it realese which means 72 hours

Muskaan Maqbool answered Mar 26, 2020
Malaria caused by plasmodium vivax is a tertian malaria I.e symptoms are shown periodically after three days...these symptoms arise due to release of haemozoin in the blood....

Punyaslok Tripathy answered Mar 08, 2020
Explanation:Hemozoin (Hz) is released into the blood stream after rupture of infected red blood cells (iRBCs) at the end of each parasite replication cycle. This free Hz is ingested by circulating and resident phagocytes. The presence of Hz in tissues after clearance of infection has been previously reported. Still, little is known about the kinetics of Hz in vivo, during and after Plasmodium infection. It is particularly important to understand Hz kinetics after malaria infections as it has been reported that Hz is associated with impairment of immune functions, including possible consequences for coinfections. Indeed, if Hz remains biologically active for prolonged periods of time inside immunocompetent cells, the potential consequences of such accumulation and presence to the immune system should be clarified.

Ans:72 hrs

Haemozoin is a malarial pigment that release every 72 hours after infection.

Raichal Raichal answered 4 weeks ago
Compare to plasmodium( vivax), (falciparum), (malaria) takes_72hr_ bcoz it take 3days to mature parasites to enter the bloodstream and begin to infect RBC but the vivax and falciparum takes 2(48hr)days to mature and infect the RBC

Tejasvi M answered May 06, 2020
Hemozoin is released after every 72 hrs.... bcoz....when sporozoites leaves the RBCs
.. using hemoglobin as it's food..releases hemozoin as it's waste which becomes toxic to the body....and it's life in RBC is 72 hrs....or you say it releases hemozoin ....after it's cycle of 72hrs

Palleboyina Rajanna answered 4 weeks ago
Hemozin is a fluid released by rupture of cell infected by plasmodium. Usually plasmodium cause malaria, during malaria the fever is at 103_104degree celsius. It caused for every 3days means every 48 to 72 hours.

Jhili Padhan answered 3 weeks ago
48 hours that i think so

Raseen Razi answered 3 weeks ago
It wil take 3 days to show the chill..it i is produced by heamozoin

Krishna Kumar Bind answered May 04, 2020
As we know that hemozoin is responsible for the chill and high fever. It affects Blood in about 72 to 96 hours. So the option B is correct.

Mahadev Mundhe answered 3 weeks ago
72 hrs hence option B

Tejaswini Kammari answered 4 weeks ago

48 hour is right answer,finally

Revathi Narasimman answered 4 days ago
Just relate it buddy. we know that haemozoin is responsible for the recurring fever or chilliness every three to four days. hence it is obvious that haemozoin will be released every 3 to 4 days which means every 72 to 96 hours.

Ansh Vishwakarma answered Apr 21, 2020

Harsh Gandhi answered 5 days ago
According to me answer is 48 hour

Arushi Thakur answered Mar 29, 2020
If we talk about normal malaria then its most common symptom are bouts of fever in every 3 days which means that it releases its toxin after every three days hence ans. shoul be 72hrs.

Abimel Sbkulumala answered May 18, 2020
Option B becaus hemozoin is ingested by circulating and resident phagocytes. One study investigated the percentage of Hz-containing granulocytes and monocytes in circulation as a predictor of disease outcome , while another reported median half-lives of 72 hours for Hz-containing granulocytes and 216 hours for Hz-containing monocytes in circulation Although the prolonged presence of Hz in tissues of individuals that had suffered from Plasmodium infections has been reported since the 19th century little is known about the long-term kinetics of Hz in vivo.

Ross cycle in life cycle of mosquito takes duration of three days which result in release of hemozoin into blood

Ayan Kumar answered May 26, 2020
New user in the question hemozoin is secreted when the the malaria affect the human body and Richard the liver cells it is ruptured then the hemoglobin is secreted from the body which is feels fever chills and finally the body is.

so in the process for the hormone during secretion in the body it needs time broccoli 3 days for 72 hours and needed in the process it is curable.

it is curable by the the drug sodium hydroxidequion

Sreya Prem answered 3 weeks ago
72 hours bcs it takes 3 days.3×24hrs=72hrs.

Devi Sasikumar answered 3 days ago
I think the answer is (b) 48 hrs. I referred a few sites and this is what I got: In malaria, at the end of each Plasmodium replication cycle, infected red blood cells (iRBCs) rupture and release merozoites, together with hemozoin (Hz), into the blood stream.

Siddhi Mishra answered May 01, 2020
