Abnormal condition of
blood elements/ Different types of Blood diseases.
The differences in the
standard amount of various elements in blood are called abnormal condition of
blood e.g.-
a) Polycithimia:
The number of RBC increases than the normal condition.
b) Anemia:
The number of RBC or hemoglobin decreases than the normal condition.
c) Leukemia:
The number of WBC increases due to pneumonia, plague or cholera. If the number
of WBC is abnormally high, that is, 50000 – 100000 then that is called leukemia
or blood cancer.
d) Leucocytosis:
If the number of WBC increases to 20000 – 30000 then that is called the
leucocytosis. Pneumonia and whoofing cough are the causes of this disease.
e) Thrombocytosis:
The number of platelets becomes higher than the normal. Clotting blood in the
blood vessels is called thrombosis. If the blood is clotted in the coronary
vessels of the heart, that is called coronary thrombosis. If the blood is clotted
in cerebrum, that is called cerebral thrombosis.
f) Parpura:
Perpura is caused by dengue fever. The number of platelets decreases than the
normal.
g) Thalassemia:
Thalassemia is a hiredatory disease of blood that affects a person’s ability to
produce hemoglobin, resulting in anemia. This disease is passed to children by
parents who carry the mutated thalassemia gene. Normally this disease is
identified in childhood. The treatment of thalassemia involves regular blood transfusions
after every three months.
