The symptoms that might be caused by the increase in amount of erythropoietin (EPO). Introduction: Erythropoietin is a hormone secreted by kidneys in response to hypoxia (low oxygen levels in the blood). It travels to bone marrow through blood and stimulates the production of red blood cells which in turn increases the oxygen carrying capacity of the blood. Athletes often misuse this hormone to increase their endurance and performance.

Expert Solution & Answer

Explanation of Solution

Certain kidney tumors can also result in elevated production of EPO. The increased production of EPO can lead to increase in number of red blood cells, a condition called polycythemia.

The excessive production of EPO can also lead to increase in hematocrit level (percentage of the total blood volume occupied by the red blood cells). The normal value of hematocrit is 40-54 % while in certain kidney cancers it can rise above 50 %.

The increased amount of EPO can produce a number of symptoms in the body such as enlarged spleen, enlarged liver, headache and vertigo. It can also lead to blood clotting and strokes, if dehydration occurs.

Conclusion

The symptoms caused by the increased amount of EPO include polycythemia, increased hematocrit value, enlarged spleen, enlarged liver, vertigo and headache.

Students have asked these similar questions

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
