ABSTRACT
Objective To study the expression of interleukin-2 (IL-2), soluble interleukin-2 receptor (sIL-2R),determine the alteration of erythrocytic immunity and T cell subgroup in the blood of outer circulation in patients with hypertensive cerebral hemorrhage so and to probe into the relationship between them, and to explore the clinical significance. Methods Enzyme linked immnunosorbent assay (ELISA) was used to determine the content of IL-2 and sIL-2R. The immunoadsorption was employed to examine the erythrocytic immune activity and its regulating function.Streptavidin-peroxidase(S-P) was used to determine the cell number of CD3 (cluster of differentiation3), CD4 and CD8. Results The content of IL-2 in the group with hypertensive cerebral hemorrhage was significantly lower than that in the control group (P＜0.01), and the content of sIL-2R increased. Red blood cell C3b receptor (RBC. C3b R)and RBC immune adherence enhancing factor (RFEB) dropped greatly (P＜0.01), while RBC immune complex rosette (RBC. ICR) and RBC immune adherence inhibiting factor (RFIR) increased greatly. The cell number of CD3 and CD4decreased (P＜0.01) and there was no obvious change in CD8 (P＜0.05). Conclusion The decrease of immune function was observed in patients with hypertensive cerebral hemorrhage. The determination of the content of IL-2, sIL-2R, erythrocytic immunity and the activity of T subgroup has an important clinical significance in the occurrence,development, treatment, and prognosis of hypertensive cerebral hemorrhage.

ABSTRACT
Objective To investigate the effects of three procedures for benign prostatic hyperplasia (BPH) on neuroendocrine and immune responses and its clinical significance. Methods Patients were divided into three groups with 20 patients in each group: the Group Ⅰreceived the transuretheral resection of prostate (TURP), the Group Ⅱ received the suprapubic transvesical prostatectomy (SPP) and the Group Ⅲ underwent the retropubic prevesical prostatectomy (RPP). The pre- and post- operative serum concentrations of Interleukin-6 (IL-6) and cortisol as well as changes of T-cell subgroups in the three groups were analyzed , respectively. Results Serum IL-6 concentrations remarkably increased at the third postoperative hour in patients of all the three groups, but those in Group Ⅱ and Group Ⅲ were significantly higher than those in Group Ⅰ( P 0 05). The ratio of CD 4 +/CD 8 + decreased markedly on the second postoperative day in Group Ⅱ and Group Ⅲ ( P
ABSTRACT
AIM To study the therapeutic action of leflunomide(Lef) on adjuvant arthritis (AA) rats and its mechanisms. METHODS To observe the change of secondary inflammation,immune function on adjuvant arthritis(AA) rats treated with Lef and to detect the effect of A 771726 —the active product of Lef on T cell subgroup in mice in vitro .RESULTS Lef(2,6,18 mg?kg -1 ?12 d) intragastric injection(ig) could signifcantly inhibit secondary reaction (secondary inflammatory swelling、 multiple arthritis) of AA rats.Lef couldnt effect the lowed response of Con A induced splenolytes, and the decreased IL 2 synthesis in AA rats. But lef(2,6,18 mg?kg -1 ) could inhibit the elevated IL 1 released from peritoneal macrophage (PM?) in AA rats. A 771726 —the active product of Lef(0 1,0 5,2 5,12 5,25,100 ?mol?L -1 ) could inhibit Con A induced T h cells but has no effect in Con A induced T s cells in vitro .CONCLUSION Lef has therapeutic action on AA rats which could be related to its immunosuppressory activities——mainly through inhibit cell mediated immunity.
ABSTRACT
AIM To study the antiinflammatory and immunomodulatory effects of actarit(Acta). METHODS To abserve the change of primary and secondary inflammation,immune function on adjuvant arthritis(AA) rats treated with Acta and to detect the effect of Acta on T cell subgroup in mice in vitro. RESULTS Acta(10,30,90 mg?kg -1 ) intragastric injection(ig) did not significantly inhibit primary reaction of AA in rats. But Acta(10,30,90 mg?kg -1 ?11 d) ig signifcantly inhibited secondary reaction (secondary inflammatory swelling、 multiple arthritis) of AA rats. The lowered response of ConA induced splenolytes and the decreased IL 2 synthesis were restored to normal in AA rats treated with Acta, while the elevated IL 1 released from peritoneal macrophate (PM?) was reduced. Acta(1～100 ?mol?L -1 ) could inhibit ConA induced T h cells and enhance ConA induced T s cells culture in vitro . CONCLUSION Acta do not show obvious antiinflammatory action. But Acta has therapeutic action on AA rats, which may be related to its immunomodulatory activities,mainly through modulate cell mediated immunity.
ABSTRACT
Objective To investigate the changes of serum immunoglobulin E(IgE)?T cell subgroups and cytokines in asthmatic children and to provide theoretical basis for the management of asthmatic children.Methods T cell subgroups were determined by indirect immuofluorence method mono clone antibody, the detection of IgE,interleukin(IL) 4,IL 6,IL 8,interferon ?(IFN ?) were done by ELISA method, and 20 normal children were served as control group.Results There were significant differences of CD3 +,CD4 +,CD4 +/CD8 + among the stages of exacerbation and convalescence of asthmatic children and control group.( P0.05).In the stage of convalescence the levels of IL 2,IFN ? were lower than control group( P0.05).Conclusions Allergic asthmatic patients between the exacerbation and convalescence stages still had immunologic imbalance,indicating increased number of CD4 +T cell(mainly Th2 cells)and hyperfunction;the insufficient number and(or) the inactivity of CD8 +T cell may induce immunological disturbance ,which is the major mechanism of asthmatic attacks. These findings suggest the patients in an abnormal immunological state should receive continuous anti allergic therapy.
