The cyanide anion is an inhibitor of the enzyme cytochrome c oxidase (also known as aa 3), the fourth complex of the electron transport chain found in the inner membrane of the mitochondria of eukaryotic cells. It attaches to the iron within this protein. The binding of cyanide to this enzyme prevents transport of electrons from cytochrome c to ...
Cyanide ions interfere with cellular respiration, resulting in the body's tissues being unable to use oxygen. [2] Diagnosis is often difficult. [2] It may be suspected in a person following a house fire who has a decreased level of consciousness, low blood pressure, or high lactic acid. [2] Blood levels of cyanide can be measured but take time. [2]
Red blood cells are circular, biconcave, disk-shaped and deformable to allow them to squeeze through narrow capillaries. They do not have a nucleus. Red blood cells are much smaller than most other human cells. RBCs are formed in the red bone marrow from hematopoietic stem cells in a process known as erythropoiesis. In adults, about 2.4 million ...
The blood of people killed by blood agents is bright red, because the agents inhibit the use of the oxygen in it by the body's cells. [2] Cyanide poisoning can be detected by the presence of thiocyanate or cyanide in the blood, a smell of bitter almonds, or respiratory tract inflammations and congestions in the case of cyanogen chloride ...
The formed elements are the two types of blood cell or corpuscle – the red blood cells, (erythrocytes) and white blood cells (leukocytes), and the cell fragments called platelets [12] that are involved in clotting. By volume, the red blood cells constitute about 45% of whole blood, the plasma about 54.3%, and white cells about 0.7%.
Initial autopsy results showed traces of cyanide in the blood of six Vietnamese and American guests at a central Bangkok luxury hotel and one of them is believed to have poisoned the others over a ...

Haematopoiesis (/ h ɪ ˌ m æ t ə p ɔɪ ˈ iː s ɪ s, ˌ h iː m ə t oʊ-, ˌ h ɛ m ə-/; [1] [2] from Ancient Greek αἷμα (haîma) 'blood' and ποιεῖν (poieîn) 'to make'; also hematopoiesis in American English, sometimes h(a)emopoiesis) is the formation of blood cellular ...
BANGKOK (Reuters) -Cyanide poisoning caused the deaths of six foreigners whose bodies were found in a room in a plush Bangkok hotel, Thai authorities said on Wednesday, with the suspected killer ...
