OBJECTIVEThis study aimed to conduct a preliminary study on the possible role and significance of interleukin (IL)-12 and IL-27 in the pathogeneses of oral lichen planus (OLP).

METHODSThirty cases of patients with OLP (fifteen cases of reticular OLP and fifteen cases of erosive OLP) were enrolled in this study, and twenty cases of healthy people served as controls. Lymphocyte subsets CD3+, CD4+, CD8+, CD19+, and CD16+56 [natural killer cell (NK)] were tested using flow cytometry, and humoral immunity [immunoglobulin (Ig)G, IgA, IgM, C3, C4] were examined using nephelometry assays. IL-12 and IL-27 contents in serum of patients with OLP and normal controls were detected through enzyme linked immunosorbent assay. The correlations between the levels of IL-12, IL-27, immune status, and clinical characteristics of patients with OLP were analyzed, respectively.

RESULTSCD3+, CD4+, and CD8+in patients with OLP were markedly lower than the normal value, whereas CD 19+ of OLP in patients was significantly higher than the normal value (P<0.05). IgM inpatients with OLP was increased, whereas C4 was declined (P<0.05). IL-12 and IL-27 levels showed significant upregulation or ULF patients compared with control groups (P<0.05). Meanwhile, positive correlations existed between IL-12 andIL-27 levels in the serum of patients with OLP (r=0.912, P<0.01). No significant correlations of IL-12 and IL-27 epressions with clinical characteristics of OLP were found (P>0.05). Negative correlations of IL-12 and IL-27 levels with CD16+56(NK) cells were observed (r1 = -0.416, P1 = 0.022; r2 = -0.392, P2=0.032, respectively), whereas a positive correlation existed for IgG (r1=0.445, P1=0.014; n=0.549, P2=0.002, respectively).

CONCLUSIONA cellular immune dysfunction mainly dominate in patients with OLP, accompanied by some degree of humoral-immunity-function disorder. The abnormally high expressions of IL-12 and IL-27 are possibly synergized and promoted inflammation development in OLP. Its promotion takes place through the negatie feedback regulation of humoral immune responses, which are involved in the regulation of immune mechanisms of OLP.

Serum IL-10 level in Kawasaki disease(KD) was tested. In the KD patients' sera during the acute phase, the levels of IL-10 were markedly elevated (122.0 +/- 39.1 pg/ml) compared to 3.7 +/- 1.7 pg/ml in the control subjects (p< 0.001). The serum IL-10 levels remained elevated in the subacute phase (16. 7 +/- 9.7 pg/ml, p< 0.001) and were restored to the normal levels(7.9 +/- 3.9 pg/ml) during the convalescent phase. In the patients with acute febrile disease, the serum IL-10 level increased significantly (34.4 +/- 14.1 pg/ml, p< 0.001) compared to that of the age-matched control subjects, but were not as high as in acute phase of KD(p< 0.005). This increase in serum IL-10 levels in KD may contribute to the up-regulation of humoral immunity and to the down-regulation of acute inflammation due to an increase in proinflammatory cytokines.

OBJECTIVEThis study examined the changes of serum levels of interleukin 12 ( IL-12), transforming growth factor beta 1 (TGFbeta 1) and immunoglobulin E ( IgE) in children with asthma as well as the correlation of IL-12 and TGFbeta 1 with IgE in order to investigate their roles in asthma.

METHODSSerum levels of IL-12 , TGFbeta 1 and IgE were detected using ELISA in 85 asthmatic children at the acute and the remission stages. Thirty healthy children served as control group.

RESULTSCompared with the control group, serum IL-12 and TGFbeta 1 levels were significantly lower and serum IgE levels were significantly higher in the asthmatic group through the acute to the remission stages. Serum IL-12 and TGFbeta 1 levels (40.42+/-15.26 ng/L and 65.41+/-22.38 pg/mL) significantly increased in the asthmatic group at the remission stage compared with those at the acute stage (28.42+/-10.73 ng/L and 40.25+/-11.73 pg/mL) (P<0.01), but remained lower levels than those in the control group (67.42+/-20.58 ng/L and 178.54+/-90.56 pg/mL) (P<0.01). The asthmatic patients at the remission stage showed significantly decreased serum IgE levels (145.67 +/-51.25 IU/mL) compared with those at the acute stage (280.35 +/-80.54 IU/mL) (P<0.01), but the IgE level in the remission stage was obviously higher than in the control group (53.61+/-13.32 IU/mL) (P<0.01). Serum IL-12 and TGFbeta 1 levels were negatively correlated with serum IgE level in asthmatic children.

CONCLUSIONSThere might be an imbalance in serum IL-12, TGFbeta 1 and IgE levels in asthmatic children. IL-12, TGFbeta 1 and IgE may play an important role in the pathogenesis of asthma. They may be useful in the diagnosis and severity evaluation of asthma.

OBJECTIVE: To study the role of serum IL-10, 12, 13, 16 in patients with allergic rhinitis and vasomotor rhinitis. METHOD: The serum levels of IL-10, 12, 13, 16 were measured by ELISA in 30 cases of allergic rhinitis, 25 cases of vasomotor rhinitis and 20 healthy people. RESULT: The level of IL-12 in allergic rhinitis was (170.33 +/- 90.58) ng/L, which was significantly lower than that of normal controls [(376.69 +/- 140.70) ng/L, P < 0.01]. The levels of IL-13 and IL-16 in allergic rhinitis were (408.51 +/- 189.68) ng/L and (151.53 +/- 63.56) ng/L, which were significantly higher than those of normal controls [(151.92 +/- 85.08) ng/L, (60.65 +/- 32.45) ng/L, P < 0.01]. There were no significant difference of levels of IL-10, 13, 16 between vasomotor rhinitis and normal controls, while the level of IL-12 in vasomotor rhinitis was lower than that of normal controls [(196.03 +/- 96.31) ng/L vs. (376.69 +/- 140.70) ng/L, P < 0.01]. It was suggested that IL-10 had positive correlation with IL-12 (r = 0.73, P < 0.01), and IL-13 had positive correlation with IL-16 (r = 0.94, P < 0.01). CONCLUSION The imbalance of IL-12, IL-13 and IL-16 play crucial roles of regulation in the onset and developing of allergic rhinitis. Further research is needed on the role of IL-12 in vasomotor rhinitis.

OBJECTIVETo explore the diagnostic values of interleukin-12 (IL-12) and interferon-γ (IFN-γ) for the patients with acute leukemia (AL).

METHODSA total of 76 cases of AL were enrolled in this study, and the 40 healthy persons were used as control group. The levels of IL-12 and IFN-γ were determined by enzyme linked immunosorbent assay (ELISA). The results were analyzed.

RESULTSThe levels of IL-12 and IFN-γ in the untreated AL group, ALL and ANLL groups were lower significantly than those in the control group (P<0.05), there was no significant difference between untreated AL and ANLL groups (P>0.05). The levels of IL-12 and IFN-γ in CR patients of AL group after treatment obviously higher than that of patients before treatment (P<0.05), but there was no significant difference as campared with that in control. The levels of IL-12 and IFN-γ in NR patients of AL group after treatment were obviously lower than that in control group (P<0.05), but there was no significant difference in comparision with patients before treatment (P>0.05). The levels of IL-12 and IFN-γ of AL-CR and AL-NR patients before treatment were not significant difference before treatment (P>0.05). The levels of IL-12 and IFN-γ of AL-CR patients obviously higher than that in AL-NR patients (P<0.05). According to immure classification, the levels of IL-12 and IFN-γ of patients in untreated group were not significant difference. In regard to the clinical risk degree, the level of IL-12 of patients in untreated group was not obvious difference (P>0.05), but the level of IFN-γ of patients in untreated group was obvious different (P<0.05). The level of IL-12 of patients in untreated group positively correlated with level of IFN-γ (r=0.735, P<0.05), but the level of IL-12 did not significantly correlated with the level of IFN-γ (r=0.292, P>0.05).

CONCLUSIONThe serum levels of both IL-12 and IFN-γ are lower, but the changes of both serum levels may be helpful to diagnose and treatment of AL patients.

OBJECTIVETo observe the clinical efficacy of Huangqi Fuzheng Decoction (HQFZD) in treating recurrent genital herpes (RGH) and its influence on related cytokines in peripheral blood.

METHODSEighty-four patients with RGH were randomly assigned to 3 groups, the treated group treated with HQFZD (31 cases), the control group A (25 cases) treated with Aciclovir, and the control group B (28 cases) treated with Aciclovir plus interferon. The course of treatment was 3 weeks for all. The relapse rate was estimated at 6 months after treatment, and levels of IL-4, IL-10, IL-12 and IL-18 in all patients were detected before and after treatment using double-sandwich ELISA.

RESULTSAll patients were cured after treatment. The relapse rate in the treated group and the control group B was lower than that in the control group A (P < 0.01) but insignificant difference was shown between the former two groups. Before treatment, patients' serum levels of IL-4 and IL-10 were significantly higher while those of IL-12 and IL-18 were lower than the normal range (P < 0.01). The abnormal change aforementioned reversed after treatment in the treated group and the control group B (P < 0.05 or P < 0.01), showing a superior effect to that in the control group A (P < 0.01).

CONCLUSIONHQFZD can reduce the relapse rate of RGH without obvious adverse reaction, and it could also enhance the immunity of the patients.

AIMTo observe the levels of interleukin-12 (IL-12) and platelet activating factor (PAF) in severe acute pancreatitis (SAP) in rats and the efficacy of Ginkgolide B (BN52021) in treating SAP.

METHODSWistar rats were randomly divided into 3 groups: model group (SAP), treatment group (BN) and negative control group (NC). SAP was induced by retrograde infusion of 5% sodium taurocholate into the pancreatic duct in Wistar rats. NC rats only receive abdominal incision. In groups of SAP and NC rats received the femoral vein injection of isotonic Na chloride 15 minutes after induction of SAP; in BN group,rats received BN52021 instead. After operation rats were sacrificed at 1, 6 and 12 hour for plasma IL-12 and PAF determined with ELISA.

RESULTSAn increase of IL-12 in group BN was observed VS group SAP or group NC at 1 h stage (p = 0.011, P < 0.01). At 6 h or 12 h stage,an increase of IL-12 in group SAP was observed VS group NC (P < 0.01, P < 0.05). The plasma level of PAF in group SAP or group BN was increased significantly at 1 h time stage VS group NC (P < 0.001). At 6 h or 12 h stage, a decrease of PAF in group BN or group NC was observed VS group SAP (P < 0.05, P < 0.01).

CONCLUSIONIt confirmed that the plasma level of cytokine IL-12 in SAP group was decreased significantly in early stage and it witnessed a remarkable increase of cytokine PAF. The plasma level of IL-12 was increased in early stage but PAF was decreased in rats treatment by BN52021 which inhibited the development of SAP.

PURPOSE: Abnormal activation patterns of Th1/Th2-cells have been suggested to increase the prevalence of allergic diseases. Prevention is regarded as an important corner stone in the management of allergic diseases. In this study, we have investigated the relationship between cord blood levels of IL-4, IL-10, and IL-12 in preterm newborns and the development of allergic respiratory diseases in infancy METHODS: Forty-six preterm newborns born at the Ewha Womans University Mokdong Hospital between January 2003 and July 2005, were enrolled for this study, and consent was obtained to test their cord blood samples. Clinical history was obtained from the hospital records. Cord blood was obtained at birth and kept frozen until it was tested. The levels of IL-4, IL-10, and IL-12 were determined by enzyme-linked immunosorbent assay (ELISA). RESULTS: All infants were followed-up for a median of 16.0 months+/-13.2 d (range, 12.0 to 36.0 months). Eighteen infants who developed wheezing showed lower cord blood levels of IL-12 (366.60+/-140.40 vs 435.09+/-91.20 pg/mL, P=0.009). Cord blood levels of IL-4 and IL-10 showed no significant difference between the two groups. Four newborns who later developed asthma, and infants with asthma showed lower IL-12 level in the cord blood than other groups. CONCLUSION: Lower concentration of cord blood levels of IL-12 in newborns who later developed wheezing and asthma suggested that they had abnormal activation patterns of Th1/Th2-cells at the time of birth, and cord blood IL-12 level can be used as a predictor of allergic respiratory diseases.
