  • Objectives : We investigated the effect of Dohongsamul-tang (DHSMT) on the production of various cytokines in lipopolysaccaride (LPS) stimulated peripheral mononuclear cells (PBMCs) from CI patients. Methods: Cell viability was determined using MTT assay. ELISA was carried out for investigating $TNF-{\alpha}$, $IL-1{\beta}$, IL-6, IL-8, IL-4, and $TGF-{\beta}$ 1 Results : The amount of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$, IL-6, IL-8, IL-4, and transforming growth factor(TGF)-${\beta}$ 1 in PBMC culture supernatant significantly increased in the LPS treated cells compared to unstimulated cells. We show that DHSMT inhibited the production of TNF-${\alpha}$, IL-1${\beta}$, IL-6, IL-8, and IL-4 induced by LPS in a dose dependent manner. The maximal inhibition rate of the TNF-${\alpha}$, IL-1${\beta}$, IL-6, IL-8, and IL-4 production by pretreatment of DHSMT (1.0mg/ml) was 38.52 ${\pm}$ 2.5% (P < 0.01), 44.02 ${\pm}$ 3.5% (P < 0.05), 45.32 ${\pm}$ 2.3% (P < 0.01), 42.30 ${\pm}$ 3.1% (P < 0.05), and 49.70 ${\pm}$ 3.1%(P &lt; 0.05), respectively. On the other hand, DMSMT significantly increased the LPS-induced TGF-${\beta}$ 1 production(P<0.05). Conclusions : Taken together. these results suggest that DHSMT might have regulatory effects on cytokine production, which might explain its beneficial effect in the treatment of CI.

  • The etiology and pathophysiology of schizophrenia remain unknown. It has been postulated that infectious-autoimmune process may play a role in the pathogenesis of symptoms in some schizophrenic patients. Findings of altered interleukin(IL) regulation have been regarded as additional proof that schzophrenia has an infectious-autoimmune background. In the present study, we measured mitogen-stimulated production of and serum level of IL-$1{\beta}$, IL-2, IL-6 using ELISA in 16 neuroleptic-free schizophrenic patients and in 16 age, sex matched healthy controls. The results were as follows : 1) There was a significant decrease of IL-2 production in schizophrenic patients than in normal controls(respectively $1.90{\pm}0.13ng/m{\ell}$, $2.79{\pm}0.14ng/m{\ell}$, p<0.001). But there was no significant difference of IL-$1{\beta}$ production and IL-6 production between schizophrenic patients and normal controls. 2) There was a significant increase of serum level of IL-2 in schizophrenic pateitns than in normal controls(respectively $184.8{\pm}12.8pg/m{\ell}$, $104.2{\pm}34.2pg/m{\ell}$, p<0.01). Serum level of IL-$1{\beta}$ was partially detected in both groups and serum level of IL-6 was not detected in both groups. 3) There was no significant differences of IL-$1{\beta}$, -2, -6 production & serum level of IL-2 according to male vs female, paranoid type vs undifferentiated type, drug-naive group vs drug-free group in schizophrenic patients. 4) There was significant correlation between IL-$1{\beta}$ and IL-6 production(r=0.86, p<0.001). No correlation between IL-$1{\beta}$, -2, -6 production, serum level of IL-2 and age, duration of illness, and BPRS score was found. It has been suggested that the low lymphocyte production of IL-2 in the patients with autoimmune disease occurs because the T cells are activated and lymphocyte-derived IL-2 has been released into the serum. The authors suggest that decreased IL-2 production in our schizophrenic patients is due to increased IL-2 serum level in those patients. Thus our finding of low IL-2 production and high serum level of IL-2 in our schizophrenic patients is compatible with the possibility that our patients have an autoimmune process. Further study on relationship between IL alteration and other immunological abnormalities(the presence of serum autoantibody and of anti-brain antibody, $CD4^+$, $CD8^+$ cell index, etc) in schizophrenic patients will be warranted.

  • Interleukin-1b ($IL-1{\beta}$), a proinflammatory cytokine, regulates the innate immune responses against bacterial infection. Mature $IL-1{\beta}$ is produced from $pro-IL-1{\beta}$ by activated caspase-1, which in turn is activated by the inflammasome complex formation. In this study, we compared the inflammasome mRNA expression induced by S. sanguinis, S. oralis, F. nucleatum and P. intermedia. Among the tested bacteria, S. sanguinis induced the highest $IL-1{\beta}$ secretion. S. oralis, F. nucleatum and P. intermedia induced very weak $IL-1{\beta}$ secretion. S. sanguinis mostly induced the NLRP3 mRNA expressions. Although F. nucleatum did not induce high $IL-1{\beta}$ secretion, it induced high expression levels of AIM2, NLRP2, and NLRP3. No specific inflammasomes were induced by S. oralis and P.intermedia. Studying the inflammasome complex activation induced by oral bacteria may thus enhance our understanding of the pathogenesis of oral diseases.

  • Berberine has shown a number of beneficial effects, including anti-tumor, anti-inflammation, and vasodilatory effects. In this work we investigated the effects of berberine on the production of proinflammatory cytokines such as TNF-$\alpha$, IL-$1{\beta}$, and IL-6 in mice. The supernatants of cultured splenocytes exposed with berberine or berberine plus LPS were harvested to assay TNF-$\alpha$, IL-$1{\beta}$, and IL-6. The sera from the mice injected with berberine or berberine plus LPS were then isolated to assay these cytokines. The TNF-$\alpha$ production in mice splenocyte cultures exposed to berberine was inhibited compared to the PBS control. The sera from LPS plus berberine injected mice showed lower levels of TNF-$\alpha$ compared to those of LPS only injected mice. The IL-$1{\beta}$ production in mice splenocyte cultures exposed to berberine was inhibited at a high dose (3.0 ${\mu}g/ml$) compared to the PBS control. Also, the increase of IL-$1{\beta}$ by LPS exposure in splenocyte cultures was inhibited by a high dose of berberine. The IL-6 in splenocyte culture supernatants showed lower levels after berberine compared to the PBS control. Also, production of IL-6 after LPS exposure in splenocyte cultures was inhibited by a low dose of berberine (0.3 ${\mu}g/ml$). These findings suggest the probability that berberine down-regulates the production of proinflammatory cytokines such as TNF-$\alpha$, IL-$1{\beta}$, and IL-6.

  • Bone remodeling is a complex process regulated by various mediators. Cytokines are known to be associated with the mechanically induced response in orthodontic tooth movement. In particular, IL-$1\beta$ stimulates bone resorption and induces osteoclast proliferation. The purpose of this study was to identify and quantify IL-$1\beta$ in human gingival crevicular fluid(GCF), and to investigate the changes in its level during orthodontic tooth movement. Twelve patients(mean age of 19.2 years) were used as the subjects. An upper canine of each patient haying treatment lot distal movements served as the experimental tooth, whereas the contralateral was used as the control. The GCF of compression and tension side of the experimental teeth and the GCF of mesial side of control teeth was taken from the each subject immediately before activation, and at 1, 24, and 168 hr after initiation tooth movement. IL-$1\beta$ amount was detected by ELISA. The concentration of IL-$1\beta$ was higher in experimental group than in the control group after treatment. Its level was elevated after initiation of tooth movement and it was the highest level at 24 hr in compression side of experimental group. But there was no significant change in control group. The results indicate that the change in IL-$1\beta$ level in GCF is associated with orthodontic tooth movement.

  • Purpose: To investigate temporal changes in IL-1${\beta}$ mRNA expression in spinal dorsal horn (DH) and dorsal root ganglion (DRG) in a rat lumbar disc herniation (LDH) model. Methods: Autologous nucleus pulposus, harvested from the tail disc between the second and third coccygeal vertebrae (Co2-3), was implanted next to the left L5 nerve root just proximal to the DRG after partial laminectomy. IL-1${\beta}$ mRNA expression was investigated in DRG and DH in our LDH model. Real-time PCR assays were done using a 7500 Real Time PCR system (Applied Biosystems, USA). Results: Expression of IL-1${\beta}$ in DRG and DH was observed for 30 days postoperatively. Expression of IL-1${\beta}$ mRNA in the ipsilateral DRG of the LDH group gradually increased from 5 to 30 days after surgery. The amount of IL-1${\beta}$ in the contralateral DRG peaked 10 days after surgery and then gradually decreased. However, there was no difference in IL-1${\beta}$ mRNA expression in spinal DH between the LDH group and the sham-operated group. Conclusion: Long-term expression of IL-1${\beta}$ in the LDH model may worsen the chronic pain state. Future studies on inhibition of IL-1${\beta}$ expression in the LDH model will be needed to develop selective treatment strategies for patients with LDH.

  • This experiment was designed to investigate the effect of Phellodendron amurense(PLDA) on the Alzheimer's disease. The effects of PLDA extract on $IL-1{\beta}$, IL-6, amyloid precursor proteins(APP), acetylcholinesterase(AChE), glial fibrillary acidic protein(GFAP) mRNA of PC-12 cell treated by $A{\beta}$ plus $rIL-1{\beta}$ and AChE activity of PC-12 cell lysate treated by $A{\beta}$ plus $rIL-1{\beta}$ and behavior of memory deficit mice induced by scopolamine and mice glucose, uric acid, AChE activity of memory deficit rats induced by scopolamine were investigated, respectively. PLDA extract suppressed $IL-1{\beta}$, IL-6, APP, AChE, GFAP mRNA in PC-12 cell treated by $A{\beta}$ plus $rIL-1{\beta}$ ; AChE activity in cell lysate of PC-12 cell treated by $A{\beta}$ plus $rIL-1{\beta}$. PLDA extract increased glucose, decreased uric acid and AChE significantly in the serum of the memory deficit rats induced by scopolamine. PLDA extract group showed significantly inhibitory effect on the memory deficit of mice induced by scopolamine in the experiment of Morris water maze. According to the above results, it is suggested that PLDA extract might be usefully applied for prevention and treatment of Alzheimer's disease.

  • Contact hypersensitivity (CHS) serves as a good model of cell-mediated reaction. Epidermal langerhans cell (LC) are thought to playa crucial role in the regulation of immune reaction of the skin, which elicit the CHS response by presenting Antigen to trafficking Ag-specific T cells within the skin. However, contact hypersensitivity is regarded as a negative side of immunities, caused by increased damaging immune response. Therefore, the study of effector molecule causing immune suppression is thought to be meaningful in the skin immune response. For this aim, this study investigated the influence of pedunculagin on cytokine, IL-$\beta$ expression from langerhans cell (LC). In vitro and in vivo, pedunculagin up-regulated the expression of IL-1$\beta$ mRNA. After PMA stimulation in vitro and DNFB sensitization in vivo, the expression of IL-1$\beta$ mRNA was down-regulated. This results suggested that pedunculagin could be immuno-modulator in skin immune system by modulating IL-1$\beta$ expression.

  • We investigated the in vivo effect of an aquous extract from Rhois Galla (R-G) on glucokinase and hexokinase activities of diabetes mellitus induced by interleukin-$1{\beta}$ ($IL-1{\beta}$). After 1 week of alloxan injection, the levels of serum glucose and insulin secretion were dramatically increased, however, the insulin secretion was decreased with administration of R-G. $IL-1{\beta}$ injection allowed the serum glucose level increased and the level was decreased by R-G administration. Furthermore, we could observe that R-G was effective in recovering the levels of insulin secretion. Enzyme activities of the glucokinase and hexokinase were decreased by $IL-1{\beta}$ treatment In contrast, R-G administration to the mice allowed proportion increasing. Seemingly, when $IL-1{\beta}$ was injected to the mice, enzyme activities of the glucokinase and hexokinase were decreased. But, R-G stimulated induction of enzyme activities of the glucokinase and hexokinase as high as normal group. These results suggested that R-G is highly effective in treatment of diabetes mellitus.
