Summary Introduction

To review:

The medical terminologies.

Introduction:

To study disease and its pathogenesis, knowledge about various terminologies is necessary. Many terminologies may resemble same, but they vary in their meaning.

Expert Solution & Answer

Explanation of Solution

  • Etiology is the factor that cause an illness. Pathogenesis is the progression of disease or mechanism that leads to the diseased state.
  • Infection is a specific type of disease caused by the invasion of an infectious agent into the body, their multiplication, and reaction of the host body to that infectious agent. Disease is related to the occurrence of cases and outbreaks caused by a pathogen in a group of people.
  • Communicable disease spreads from one person to another either directly or indirectly through air, water, or food. Therefore, it is a contagious disease. Non communicable disease does not spread from person to person and they are caused by factors like allergy or malnutrition. Therefore, it is a non-contagious disease.
Conclusion

Etiology and pathogenesis, infection and disease, communicable and non-communicable disease are used in similar situations but their meaning changes significantly.

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
