[Natural killer cells and T-suppressors in patients with chronic gastritis]

In of 69 patients suffering chronic gastritis, 23 contracting gastritis in old age and 10 with gastritis aggravated by stomach ulcers, a significantly low level of natural killers was found in cases of mucosal atrophy and gastric intestinal metaplastic lesions, particularly, at an age of more than 60 years. T-suppressor level was relatively lower in patients with atrophic gastritis.
