  • The present study was conducted to evaluate the regulation mechanism of nitric oxide(NO) by water-extracted Cyperus rotundus (WCR) in RAW 264.7 macrophages. We investigated the effects of cell proliferation in mouse spleen cell and RAW 264.7 macrophages cells. WCR enhanced mitogenic activity in the dose-response manner in mouse spleen cells and RAW 264.7 macrophages cells. In nitric oxide (NO) synthesis by WCR, WCR alone had an effect on NO synthesis. It was found that the production of NO of RAW 264.7 cells stimulated with lipopolysaccharide (LPS) could be markedly inhibited by WCR. Inhibition of NO production was achieved by reducing inducible nitric oxide syntheses(iNOS) mRNA expression. The expression of IL-I gene by WCR was investigated using reverse transcription polymerase chain reaction (RT-PCR). In RT-PCR, IL-1 family(IL-1 α, IL-1β) expressions were induced by WCR. These finding suggested that regulation of NO production by WCR may be, at least in part, associated with the regulation of iNOS mRNA expression and IL-1 family gene expression.

  • In intestinal helminth infections, Th2 immune respones are generally associated with mucin secretion for worm expulsion from the host intestine. In particular, IL-4 and IL-13 are the important cytokines related with intestinal mucus production via STAT6 signalling in nematode infections. However, this perspective has never been studied in Gymnophalloides seoi infection. The present study aimed to observe the STAT6 signalling and cytokine responses in C57BL/6 mice, a mouse strain resistant to infection with this trematode. The results showed that worm expulsion occurred actively during days 1-2 post-infection (PI), when goblet cells began to proliferate in the small intestine. The STAT6 gene expression in the mouse spleen became remarkable from day 2 PI. Moreover, G. seoi infection induced a significant increase of IL-13 from day 4 PI in the spleen of infected mice. Our results suggested that goblet cell hyperplasia and worm expulsion in G. seoi-infected mice should be induced by STAT6 signalling, in which IL-13 may be involved as a dominant triggering cytokine.

  • To develop human risk assessment protocols, we explored housekeeping gene and cytokine expression in mouse spleen cells using Rt-PCR. We normalized housekeeping gene expression by RT-PCR; gene expression was highly uniform in potato leafs and mouse spleen cells. We measured the expression of frequently used housekeeping genes, such as those encoding APRT, $\beta$-tubulin, Actin, Hsp 20.2, Cyclophilin, 18S RNA, Efla, Tbp, GAPDH, $\beta$-actin, Tuba2, Hprt, Cyclophlin A, Tfrc, and RPL13A in mice fed GM or non-GM potatoes. Housekeeping gene expression did not show any significant differences between GM and non-GM potato-fed mice. The murine model of potato-fed mice did not express IL-4 and IL-13 at a significant levels.

  • In order to inverstigate interactive effects of Samultang(SMT) and SMT composition and the principle of prescription, I examined the effects of SMT and combination of three components of SMT, In C57BL/6 mouse with oral administration of SMT and cyclophosphamide(CTX) treatment, white blood cells, platelet were counted. Also, those were anti-anemia effect for rat which have hemolytic anemia induced by phenylhydrazine. The results were summerized as follows : 1. In vivo analysis of the effect of the SMT by orally administrated C57BL/6 mice with the SMT and was treated with cyclophosphamide (CTX). When the number of white blood cell. platelet was counted, there was ameliorative effects of leucopenia or thrombocytopenia as a protection to CTX. 2. It was acknowledged that SMT and its composition increased RBC count and hemlytic significantly in rat which have hemolytic anemia. 3. Among SMT composition Angelicae gigantis Radix and Cnidii Rhizoma solution and among the combination group Rehmanniae Radix and Cnidii Rhizoma combination and SMT solution showed significant effects for hemoglobin and weight of spleen in mouse which have hemolytic anemia. Thus it was acknowledged that Rehmanniae Radix and Cnidii Rhizoma combination had effect to improve hemoglobin and weight of spleen. From above these results it was acknowledged that SMT has effects that ameliorative effects of leucopenia or thrombocytopenia as a protection to CTX and anti-anemic effect for the rat which have hemolytic anemia induced by phenylhydrazine and these effects depend upon its combination of SMT composition. Especially it was acknowleged, though there are the slight difference according to combination, that Paeoniae Radix Alba combination had improving effect for physical change. So it is though that Paeoniae Radix Alba is main material for this kind of disease and continuous study is needed.

  • Epilepsy is one of the most common neurological disorders, and topiramate (TPM) is one of the most effective drugs that can render patients seizure-free. The focus of the present study was to evaluate the immunological safety of TPM in a mouse model. We examined the in vitro effect of TPM on immune functions of BV2 microglial cells, RAW 264.7 macrophages, B cells, T cells, and dendritic cells. We also examined the in vivo effect of TPM on mouse immune organs, such as lymph node, spleen, and thymus. When cells were directly treated with TPM at concentrations from 1 to $30{\mu}g/ml$, TPM did not affect nitrite production by BV2 cells and macrophages, proliferation of B cells and T cells, or maturation of dendritic cells. In addition, TPM did not change the weight and cellularity of lymph nodes, spleen, and thymus in vivo at doses from 3 to 100 mg/kg injected i.p. into mice once a day for 4 consecutive days. These data showed that TPM, which is widely used as an anti-epileptic drug, is immunologically safe.

  • Anti-inflammatory glucocorticoid (GC) derivatives have been clinically used in immune-malfunctional diseases for their immunosuppressive activity. However, there is still a lack of knowledge on the relationship between anti-inflammatory and immunosuppressive activities. In order to compare immunosuppressive activities with the known anti-inflammatory activities of the GC derivatives, eight clinically used GC derivatives including hydrocortisone, prednislone, 6$\alpha$-methyl prednisolone, triamcinolone, dexamethasone, betamethasone, triamcinolone acetonide and fluocinolone acetonide were selected, and lymphoblastosis inhibition and plaque-forming cell (PFC) response in mice were studied as immunological parameters. In Con A-induced lymphoblatosis inhibition invitro, all derivatives showed potent inhibition $IC_{50}$ values of the derivaties except methyl prednisolone and triamcinolone were less than $10^{-7}$M and good dose dependency was obtained. This result was well correlated with that of their anti-inflammatory potencies obtained. This result was well correlated with that of their anti-inflammatory potencies and their receptor binding affinities. However, in PFC response, consistent result were not obtained. Total numbers of PFCs per spleen were decreased by some derivatives, but numbers of PFCs per $10^6$ cells were not decreased by systemic administration of but numbers of PFCs per $10^6$ cells were not decreased by systemic administration of GC at the dose of 0.05 mg/mouse. Furthermore, at the dose of 0.1 mg/mouse, numbers of PFCs per $10^6$ cells were found to be increased, although total PFCs per spleen were decreased.
