OBJECTIVE To investigate the characteristics of T lymphocytic subsets in chronic tonsillitis patients for evaluation of their clinical implication. METHODS Fresh peripheral blood samples were obtained from 54 chronic tonsillitis patients and 52 healthy counterparts. CD4+ and CD8+ T lymphocyte subsets including the naive (CD45RA+), memory (CD45RO+), functional (CD28+), activated (HLA-DR+, CD25+) and apoptosis (CD95+) T lymphocytes, were analyzed by flow cytometry, respectively. The clinical data such as serum Cystatin C con centration, ASO and ESR were simultaneously recorded from each chronic tonsillitis patient. RESULTS The CD4+ T cells, the rate of CD4+/CD8+ and CD4+ CD45RA+ /CD4+ CD45RO+, the CD4+ CD45RA+ T cells and the CD4+ CD25+ T cells in chronic tonsillitis were significantly lower than those of the control group (P < 0.05) while an obviously increasing percentage of memory (CD45RO+) and apoptosis (CD95+) T lymphocytes in chronic tonsillitis patients, and there were significant differences between the patients with chronic tonsillitis and the healthy volunteers (P < 0.05). Furthermore, in the chronic tonsillitis patients, Serum Cystatin C level was negatively correlated with CD4+ CD45RA+ T(P < 0.05), and not significantly correlated with other T lymphocyte subtypes (P > 0.05). CONCLUSIONS Immune disorder is present in the peripheral blood of chronic tonsillitis patients. Our data may provide valuable information for evaluation of disease progression of chronic tonsillitis patients.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D005434	Flow Cytometry	Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D014069	Tonsillitis	Inflammation of the tonsils, especially the PALATINE TONSILS but the ADENOIDS (pharyngeal tonsils) and lingual tonsils may also be involved. Tonsillitis usually is caused by bacterial infection. Tonsillitis may be acute, chronic, or recurrent.	Tonsillitides
D015496	CD4-Positive T-Lymphocytes	A critical subpopulation of T-lymphocytes involved in the induction of most immunological functions. The HIV virus has selective tropism for the T4 cell which expresses the CD4 phenotypic marker, a receptor for HIV. In fact, the key element in the profound immunosuppression seen in HIV infection is the depletion of this subset of T-lymphocytes.
