To examine the effects of HHCP on atopic dermatitis and its various immunopathologic parameters was induced by DNCB in NC/Nga mice and the animals were orally administrated with HHCP. We summarized the results obtained from serum levels of IgE and the numbers of various immune cells as follow. HHCP has no cytotoxic effects at the range of concentration (1-400 ${\mu}g$/ml) on fibroblast isolated from lung of BALB/c mice. HHCP significantly lowered the serum levels of IgE compared with control at 16 and 20 week. HHCP significantly reduced the number of CD19$^+$ cell in spleen and DLN, as well as the number of B220$^+$ /IgE$^+$ cell in DLN compared with control. HHCP significantly reduced the number of ${\alpha}$${\beta}$ TCR$^+$ in spleen and DLN, the number of CD8$^+$ in spleen compared with control, and also significantly reduced the number of CD3$^+$, CCR3, CD3$^+$/CD69$^+$, CD3/ CCR3, CD4$^+$, CD3$^+$/ CD4$^+$/CD45$^+$ cell in DLN. HHCP increased the number of NK$^+$ cells in spleen compared with control, in contrast significantly decreased the number of CD11c$^+$/ Classll$^+$ cell and CD11b$^+$/Gr-1$^+$ cell in DLN. Taken together, these results suggested that HHCP has suppressive effects on atopic dermatitis through the inhibition of IgE production and modulation of immune cell population in NC/Nga mice.
Objectives : To examine the effects of Gojineumja on white rats which deteriorated immunity caused by Methotrexate(MTX), first of all, MTX was fed to the rats once a day for 4 day. Methods : After the immune response of the rats are deteriorated, dried extracts of Gojineumja(GJE) mixed in water was fed to the white rats once a day for l4days.

The purposes of this study were to set up the method of the natural killer(NK) cell activity assay using the flow cytometer and to examine the characteristics and distribution of the NK cell during rat hepatocarcinogenesis. Forty five male 6 week-old specific pathogen free(SPF) Sprague-Dawley rats were randomly divided into three groups. Group I was the non-treated control and given normal diet and water. Group II was treated with diethylnitrosamine(DEN, 200mg/kg, i.p.) and partial hepatectomy. Group III was treated with DEN, partial hepatectomy and 0.05% phenobarbital sodium in water from 3 to 16 weeks. All animals were examined the morphology of the large granular lymphocyte(LGL), the LGL percent of the total lymphocytes and the LGL conjugation rate with YAC-1 cell in peripheral blood, spleen and liver. Moreover, activity of the LGL isolated from peripheral blood lymphocytes was determined using the flow cytometer. As results, LGL were observed in the peripheral blood, spleen and liver. LGL were observed the relatively faintly staining basophilic cytoplasm with granules, and eccentric, often kidney-shaped nuclei in Giemsa stain. Its size was $11{\sim}13{\mu}m$. LGL percentage of the isolated lymphocytes in peripheral blood, spleen and liver were 1.8~2.3%, 1.3~1.4% and 0.87~0.99%, respectively. LGL conjugation rate with YAC-1 cell was shown to be peripheral blood(9.3~10.3 %) > spleen(7.7~8.7%) > liver(5.6~7.0%). The activity of the LGL isolated from peripheral blood lymphocytes in Group I, II and III was 33.7%, 30.5% and 35.4%, respectively. However, all values were not significantly between groups.

APA-01, which is an aqueous extract of five Chinese herbs, is a modified formula of Huoxiang-Zhengqi-San. The effect of new herb extract on immune response was investigated. The parameter examined to assess apparent immune response of APA-01 in mice included changes of body weight, relative weight of immune organs, cell proliferation and cytokine gene expression. The body weight and relative weight of immune organs were not significantly changed among the tested groups. In the spleen cell prolijeration assay, APA-01 increased the cell proliferation in a dose-dependent manner. Methotrexate (MTX), an agent of immune suppression, inhibited the spleen cell proliferation (IC/sub 50/: 800㎍/㎖). However, APA-01 significantly inhibited the suppression of mouse spleen cell proliferation. Therefore, it seems that APA-01 has a reducing effect of immune suppression. Immunomodulatory effect of APA-01 was further investigated using reverse transcription polymerase chain reaction (RT-PCR) in mouse spleen cells. In RT-PCR test, APA-01 enhanced the expression of cyclooxygenase-2 (COX-2) mRNA in a dose-dependent manner. In spite of immune suppression by MTX, COX-2 mRNA was induced by co-treatment with APA-01. These results suggest that APA-01 stimulates the proliferation of spleen cells, regulates the expression of COX-2 mRNA, and accelerates the recovery of inhibition of spleen cell proliferation induced by MTX, thus providing the immunological basis for clinical benefit of APA-01.
Propyl gallate used as an antioxidant was examined for its effects on murine Immune system and metbemoglobin content treated with anillne. As immunotoxicology assay parameters, we adopted circulating leukocytes and immunoorgan weights for pathtoxicology, IgM plaque forming cells and Artbus reaction for humoral immunity. Propyl gallate's effects were observed as follows; 1. Propyl gallate decreased circulating leukocyte counts, dose dependently. 2. Relative immunoorgan weigbts were not affected. 3. Propyl gallate diminisbed IgM PFCs/spleen cell and IgM PFCs/spleen. 4. Propyl gallate decreased Arthus reaction. 5. Propyl gallate did not affect metbemogiobin content treated wltb aniIIne.

Primiphos-methyl and methidathion as organophosphorus (OP) pesticides were tested for their immunotoxic effects on Balb/c mice. Three dose levels of primiphos-methyl (10, 60, or 120 mg/kg/day) and methidathion (0.5, 2.5 or 5.0 mg/kg/day) were administered orally in the mice for 4 weeks. After, changes in body weight gain, relative weight of spleen and thymus, viable splenic cell numbers, surface marker on immune cell, and proliferation activity were investigated. Results showed that neither Pirimiphos-methyl nor methidathion dosages changed significantly body weight, relative thymus and spleen weight, and thymus and spleen cellularities of the mice, but high dose treatment (120 mg/kg) of pirimiphos-methyl significantly decreased relative spleen weight and spleen cellularity of the mice. No alterations were observed in changes of LPS-proliferation response of splenocytes by exposure to any dose of pirimiphos-methyl and methidathion. However, pirimiphos-methyl dosages reduced ConA-proliferation response of splenocytes and both methidathion and pirimiphos-methyl decreased the ability of antibody production to SRBC. The results indicate that 28 days exposure to the high dose of pirimiphos-methyl suppress the function of splenic T and B cell function, and methidathion reduce the immune responsibility of B cell in mice without the changes in lymphoid organ weight or viability of splenocytes. Pirimiphos-methyl is more immunotoxic than methidathion although this has higher general toxicity than that.
Hepatocellular carcinoma (HCC) is a prevalent malignant tumor with high fatality. It has yet to be reported whether circ-SNX27 can affect the progression of HCC. This study attempted to analyze circ-SNX27's precise role and underlying mechanisms in HCC. HCC cell lines and tumor specimens from HCC patients were analyzed using quantitative real-time PCR and Western blotting to quantify the expressions of circ-SNX27, miR-375, and ribophorin I (RPN1). Cell invasion and cell counting kit 8 experiments were conducted for the evaluation of HCC cell invasion and proliferation. Caspase-3 Activity Assay Kit was utilized to gauge the caspase-3 activity. Luciferase reporter and RNA immunoprecipitation assays were executed to ascertain the relationships among miR-375, circ-SNX27, and RPN1. To determine how circ-SNX27 knockdown affects the growth of HCC xenografts in vivo, tumor-bearing mouse models were constructed. Elevated expressions of circ-SNX27 and RPN1 as well as a reduced miR-375 expression were observed among HCC cells and HCC patient tumor specimens. Knocking-down circ-SNX27 in HCC cells abated their proliferative and invasive abilities but raised their caspase-3 activity. Moreover, the poor levels of circ-SNX27 inhibited HCC tumor growth among the mice. Circ-SNX27 enhanced RPN1 by competitively binding with miR-375. Silencing miR-375 in HCC cells promoted their malignant phenotypes. Nonetheless, the promotive effect of miR375 silencing was reversible via the knockdown of circ-SNX27 or RPN1. This research demonstrated that circ-SNX27 accelerated the progression of HCC by modulating the miR-375/RPN1 axis. This is indicative of circ-SNX27's potential as a target for the treatment of HCC.
