Determination of CD30 expression on peripheral blood T lymphocyte subsets in patients with hemorrhagic fever with renal syndrome by FCM

Summary To determine the CD₃₀ expression on peripheral blood T lymphocyte subsets in patients with hemorrhagic fever with renal syndrome (HFRS) and its clinical implications, double immunofluorescence technique and flow cytometry were used. There was no significant difference among the severe group, mild-moderate group and normal control group in the CD+CD₃₀ T lymphocyte subset. While the CD₄ ⁺CD₃₀ ⁻ T cells of HFRS patients were increased and the difference between severe group and mild-moderate group or normal control group were very significant (P<0.01) and the difference between the mild-moderate group and normal control group was also significant (P<0.05). The CD₈ ⁺CD₃₀ ⁻ T cells were increased while the CD₈ ⁺CD₃₀ ^- T cells decreased obviously in HFRS patients, and the differences among three groups in both subsets were very significant (P<0.01). The results showed that the humoral immunity and cellular immunity are overactive in HFRS patients during acute phase. The loss of balance between T lymphocyte subsets may play an important role in the pathophysiology of HFRS and is closely correlated with the severity of the HFRS. This project is supported by the grant of the Ministry of Health (Serial No. 96-2-116).     

The effect of magnesium on erythrocytic electrolytes in digitalis toxicity

Summary Concentrations of K⁺, Na⁺ and Mg⁺⁺ were measured in plasma (K⁺ _e, Na⁺ _e, Mg⁺⁺ _e) and in erythrocytes (K⁺ _i, Na⁺ _i, Mg⁺⁺ _i) in patients with digitalis toxicity before and after administration of Mg. K⁺ concentration in 24-hour urine was also measured. 70 persons were divided into 5 groups: (1) 11 normal persons as controls; (2) 19 patients with congestive heart failure, in whom Mg⁺⁺ _i and Mg⁺⁺ _e concentrations were found to be lower than that of the control group; (3) 16 patients with digitalis toxicity treated by Mg⁺⁺, whose K⁺ _i concentration increased much quicker, and Na⁺ _i and Na⁺ _i/K⁺ _i decreased remarkably in comparison to non-Mg treatment group; (4) 12 patients with digitalis toxicity not treated by Mg⁺⁺: in these the above-mentioned changes were not significant; (5) 12 patients with arrhythmia of other causes treated by Mg⁺⁺: whose K⁺ _i also increased significantly on the 3rd day after treatment. K⁺ concentration in 24-hour urine was much lower in Mg treatment group than in non-Mg treatment group. Besides, acute digitalis toxicity was observed in experimental dogs. The concentration of K⁺ _i recovered much quicker in Mg treatment group than in control group. These findings indicate that hypomagnesemia may induce digitalis toxicity. In this paper the possible mechanism of the therapeutic effect of Mg in the treatment of digitalis toxicity is discussed.     

Mitogenic factor for T inducer/helper cells in Entamoeba histolytica extracts

Summary In order to investigate mitogenic effect of Entamoeba histolytica extracts (EHE) on T cell subpopulations, monoclonal antibodies of the OKT system were used to separate T inducer/helper (OKT₄ ⁺) and T suppressor/cytotoxic (OKT₈ ⁺) cells. Only OKT₄ ⁺ cells were found to respond to EHE stimulation as indicated by incorporation of³HTdR into cultured cells. Determination of interleukin-2 (IL-2) activities revealed that the response of OKT₄ ⁺ cells to EHE was due to the action of IL-2.     

Effect of Tiotropium Bromide on Expression of CD_8~＋CD_（25）~＋FoxP_3~＋ Regulatory T Cells in Patients with Stable Chronic Obstructive Pulmonary Disease

The expression of CD8+CD25+FoxP3+ regulatory T cells(CD8+Tregs) in the peripheral blood of patients with stable chronic obstructive pulmonary disease(COPD),and the effect of muscarinic cholinergic receptor antagonist tiotropium bromide on the expression of CD8+Tregs were investigated.Twenty-three patients with moderate to severe stable COPD were enrolled in this study.All patients inhaled tiotropium bromide(18 μg daily) for 3 months.Before and after inhalation of tiotropium bromide,peripheral blood samples were collected from the patients,and T cells were labeled by three-color labeled monoclonal antibodies.Flow cytometry was used to detect the quantity and percentage of CD8+T cells,CD8+CD25+T cells,CD8+Tregs,CD4+T cells,CD4+CD25+T cells and CD4+CD25+FoxP3+ regulatory T cells(CD4+Tregs) respectively.The percentage of CD4+T cells was increased from(27.82±2.18)% to(35.53±1.3)%(t=3.20,P=0.004) in the peripheral blood of patients with stable COPD after inhalation of tiotropium bromide for 3 months,that of CD4+CD25+T cells was decreased from(10.03 ±1.42)% to(4.21 ±0.65)%(t=3.78,P=0.001),and that of CD8+Tregs was increased from(8.41 ±1.68)% to(21.34 ±4.20)%(t=2.72,P=0.013).At baseline,CD8+T cells,CD8+CD25+T cells and CD4+Tregs were detectable in the peripheral blood,but no significant changes were observed after treatment.Linear correlation analysis revealed that the difference before and after treatment in CD4+T cells and CD4+CD25+T cells was negatively correlated with the ratio of change in CD8+Tregs before and after treatment(r=-0.61,P=0.013;r=-0.72,P=0.001 respectively).In the peripheral blood of patients with stable COPD,there was the expression of CD8+Tregs and CD4+Tregs.Muscarinic receptor antagonist,tiotropium bromide,can promote the amplification of CD4+T cells,inhibit the expression of CD25+T cells,and enhance the expression of CD8+Tregs.CD8+Tregs and CD4+Tregs can be used as new indicators to understand the immune status of patients.They are helpful in judging the treatment efficacy and disease immunophenotype.     

Enhancement of B cell responses by the interaction of CD2 with LFA-3

Summary Potential effect of the interaction of CD₂ with its ligand LFA-3 on B cell responses in vitro was studied to evaluate the action of CD₂-LFA-3 in immune responses. It was found that: 1) addition of autologous erythrocytes to uniractional mononuclear cells resulted in enhancement of PWM-induced lymphocyte proliferation, and had no significant influence on non-mitogen stimulation; 2) autologous erythrocytes potentiated the synthesis of immunoglo bulins; and 3) costimulating effects of autologous RBC can be depressed by preincubation of PBMNC with anti-CD₂ monoclonal antibody (WuTll). The results suggest that preincubation of mononuclear cells with anti-CD₂ McAb has a down-regulating effects on B cell responses and the interaction of CD₂ with its ligand LFA-3 expressed by RBC is closely related to immune responses.
