Note, MPS developing in a committed stem cell, committed to develop granulocyte will produce chronic myeloid leukemia (CML). CML, thus, like PV, is a member of MPS. [MPS is also called MPD — myeloproliferative disease. Incidentally, syndrome means disease]. In PV, erythropoietin concentration in plasma is very low or nil (ve feed back). Note. The cancerous change in MPS occurs only in one stem cell -» therefore daughter cells of this cancerous cell alone increase in number. Ultimately the heavy cell count (produced by this cancerous clone cell), by -ve feed back, causes inhibition of the multiplication of all other (healthy) stem cells. But this -ve feed back cannot stop the multiplication of the cancerous stem cell as because it is a cancer cell. Ultimately, in PV, all RBCs are monoclonal. Secondary polycythemia develops where there is need of excess erythropoietin to produce more RBC for survival of the person. Secondary polycythemia is thus seen in, high altitude sickness, emphysema, COPD and cyanotic heart diseases. STUDY QUESTIONS: 1. What do you know about the physiological functions of the blood . 2. What elements make up blood? 3. What is hematopoiesis? 4. Where does hematopoiesis occur? 5. What are blood stem cells? 6. Describe the morphological structure of erythrocytes. 7. What are the other names for erythrocytes? 8. What is the function of these cells? 9. What is the name of the molecule in red blood cells that transports oxygen? 10. What is the molecular composition of hemoglobin? 11. Does the functionality of hemoglobin as a protein depend on its tertiary or quaternary structure? 12. Describe the morphological structure of hemoglobin. the colour test of the red cell. 13. The reactions of hemoglobin. 14. The hemoglobin in the fetus. 15. Explain the abnormalities of hemoglobin production. 16. The synthesis and catabolism of hemoglobin. 17. The red cell fragility. 18. The sedimentation rate 15. On average, what is the lifespan of a red blood cell? Where do heme groups go after the destruction of hemoglobin molecules? 16. Explain the role of the spleen for the red cells. Why can people still live after a total splenectomy (surgical removal of the spleen)? 17. What do you know about the physiological functions of the plasma. 18. The plasma proteins and its function. 19. The origin of plasma proteins.the hypoproteinemia 20. What do you know about the anemias and the polycythemia? |
