21.   This discrepancy arises from the ever present difficulty of deciding whether a particular cell could be either a lymphocyte or part of a macrophage, neutrophil, or fibroblast.

22.   These cells are probably macrophages.

23.   Ten ml labelled cells were injected into the patient.

24.   Small cells were lymphocytes with either a small round nucleus or an irregular nucleus giving a centrocyte like appearance.

25.   Tumoral ECL cells were either typical, containing vesicular electron dense granules or atypical with non-vesicular granules displaying a coarsely granular structure.

26.   It has also been shown recently that, in patients with untreated duodenal ulcer, argyrophil cells were significantly more numerous in women than in men.

27.   In the second, parietal cells extend to the pylorus, but G cells are also present in the antrum.

28.   No cells synthesising DNA are present in the upper one third and surface epithelium of normal colonic crypts.

29.   TNF cells were still however higher in ulcerative colitis than controls.

30.   If so, maternal antibodies would probably have mopped up the NFEs before their analysis, suggesting that the analysed cells are of a different type.
