If the thymus of an adult experimental animal is removed, the following observations can be made: (a) No immediate effect occurs, and (b) after 1 year, decreases occur in the number of lymphocytes in the blood, the ability to reject grafts, and the ability to produce antibodies. Explain these observations.
A white cell differential was performed for an adult female, with the following percentages of cells counted:Neutrophils = 25%, Lymphocytes = 69%, Monocytes = 5%, Eosinophils = 1%, Basophils = <1%Given that the total white cell count for this individual is 8.1x109/L, calculate the absolute number of lymphocytes per litre of blood. Discuss possible causes for any of the white cell differential counts which do not fall within the expected reference ranges.
In a patient of 60 years old after the surgical removal of stomach cancer and subsequent treatment, an enlarged lymph node in the left
supraclavicular area was detected. Atypical cells, which were similar to the cells of a previously removed tumor, were found after
the biopsy of this lymph node,
Questions:
1) What typical pathological process (TPP) has developed in the lymph node?
2) Indicate the stages of this TPP.
3) Indicate possible ways of tumor cells spreading throughout the body.
