GD68 is newly developed herb complex prescription. The constituent herbs of GD68 were Massa Medicata Fermentata, Atractylodis Rhizoma Alba, Poria, Zingiberis Siccatum Rhizoma, Crataegi Fructus, Saccarum Granorum, Agastachis Herba, Taraxaci Herba, Perillae Herba, Scutellariae Radix, Astragali Radix, Ginseng Radix, Houttuyniae Herba and Halloysitum Rubrum. The aim of this study was to examine feed value of GD68 in duck. The weight gain of ducks fed with supplemental GD68 high compared to those of the control. The feed intake and mortality of ducks fed with supplemental GD68 low compared to those of the control. The moisture, crude lipid and calorie content of the ducks fed GD68 were decreased, but the crude protein content of the ducks fed GD68 was increased. And we investigated the effect of GD68 on the production of cytokines in human T-cell line, MOLT-4 cells. GD68 plus concanavalin A (Con A) increased the interferon-$\gamma$ and interleukin-2 production compared with Con A alone. These results indicate that the supplemental GD68 may improve the production, meat quality and immunity of ducks.

To develop hybridomas secreting monoclonal antibodies to be used as unlimited sources of reagents indispensable for the diagnosis and treatement of leukemic malignancy, a monoclonal antibody was generated to human pre-T leukemia cells (Jurkat). Hybridomas were produced against Jurkat cell line by fusing spleen cells from hyperimmunized mice with murine plasmacytoma cells (P3$\times$63Ag8. V653). One monoclonal antibody derived from this fusion, designated DMJ-2 was reactive with T-cell lines (Jurkat, Molt-4 and RPMI-8402) and normal peripheral E-rosette forming T cells, but unreactive with B-cell lines (Daudi, Nalm-6) and non-T, non-B cell line (K562). Conclusively DMJ-2 reactive with mature and immature T-lineage lymphoid cells.

Objective : To demonstrate of regulatory effect of atopic allergic regulation by Chungsangbangpoong-Tang(CBT), This experiment was studied. Methods : The author investigated a possible effect of CBT on cytokines production using human T cell line (MOLT-4) or human mast cell line (HMC-1). In addition, the author investigated whether CBT has inhitory effects on compound 48/80- induced histamine release from rat peritoneal mast cells (RPMC) and compound 48/80-induced ear swelling in ICR mice. Results : CBT (0.01 mg/ml)-containing medium in stimulated culture supernatants significantly increased IL-2 secretion compared with untreated MOLT-4, whereas CBT (0.01-1.0 mg/ml)-containing medium in stimulated culture supernatants significantly decreased IL-4 secretion compared with untreated MOLT-4. Significant reduced levels of IL -6 and $TNF-{\alpha}$ were observed in the HMC-l with CBT (P<0.05). CBT did not inhibit the histamine release from the RPMC but inhibit ear swelling response. Conclusion : These results suggest that CBT contributes to the treatment of atopic allergic reactions, such as atopic dermatitis and that its action may be due to regulation of cytokine production.

In this study, the immuno-enhancing activity of seed extracts were studied on the macrophage cell lines. We examined the effect of nine seed extracts on nitric oxide (NO) production in RAW 264.7 cells and selected four highly-effective seed candidates (Fagopyrum esculentum, Taraxacum platycarpum, Impatiens balsamina, Helianthus annuus) for further immune-related studies. The effects of the four seed extracts on the production of immune-related cytokines in the RAW 264.7 macrophage cell line and proliferation of Molt-4 as a T cell line were investigated. The secretion of NO from the RAW 264.7 cells was increased up to 39 ${\mu}M$ by adding the seed extracts (25 ${\mu}g/mL$) compared to the control. Also, the secretion of tumor necrosis factor-alpha (TNF-${\alpha}$) was also increased up to 32 times by adding the seed extracts (25 ${\mu}g/mL$). Secretion of cytokines such as interleukin-1 beta (IL-$1{\beta}$), interleukin-6 (IL-6), and interleukin-10 (IL-10) was also increased and induced the proliferation of T cells compared to the control. In conclusion, these results suggest that four seed extracts provide beneficial immuno-enhancing effects for human health.

The purpose of this research was to investigate the effects of Chungjokupye-tang(CJKPT) on the anti-carcinogenic action. The cell viability of mouse spienocytes and thymocytes were enhanced by the addition of CJKPT. CJKPT were increased of splenic and thymic T lymphocytes, such as T/sub H/ cells were markedly increased by the treatment of CJKPT in vivo. CJKPT treatment induced the apoptotic cell death of Jurkat and HL60 leukemia cells. CJKPT reduced mitochondrial transmembrane potential and increased the expression of ICE, c-myc and p53 gene in Molt-4cells dose dependant manner. These results suggest that CJKPT have an anti-carcinogenic action via immunoregulatory mechanism.

Medicinal herbs have long been used as a remedy for diverse diseases in Asia owing to their various pharmacological effect. In this study, the immuno-enhancing activity of medicinal herbs was investigated using macrophage cell lines. Specifically, we examined the effects of extracts of twelve medicinal herbs on nitric oxide (NO) production in RAW 264.7 cells, and selected five that were highly effective (Glycyrrhiza glabra, Rehmannia glutinosa, Angelica gigas, Platycodon grandflorum, and Actinidia polygama) for further immune related studies. The effects of extracts from five theses medicinal herbs, which were mainly composed of polysaccharides and proteins on the production of immune-related cytokines in the RAW 264.7 macrophage cell line and the Molt-4 T cell line were investigated. The extracts of all investigated medicinal herbs increased the production of NO and cytokines such as tumor necrosis factor-alpha (TNF-${\alpha}$), interleukin-1beta (IL-$1{\beta}$), interleukin-6 (IL-6) and interleukin-10 (IL-10). Additionally, they slightly increased the proliferation of T-cells when compared to the control. Overall, the result of this study suggests that the five medicinal herb extracts investigated herein are useful natural immune enhancing agents.

We investigated the immune enhancement effects of JaSaengHwan (JSH). The forced swimming test (FST) has been used as a screening model for new immune enhancement agents. We found that JSH (0.1 mg/ml) significantly reduced the immobility time in the FST compared to the control. Also, we investigated the effect of JSH on the proliferation of T cell and production of cytokines in human T-cell line, MOLT-4 cells and mouse peritoneal macrophages. JSH (1 mg/ml) significantly increased the cell proliferation by $46.78{\pm}6.41%$ (p<0.05) and also significantly increased the interleukin (IL)-2, IL-4 and interferon $(IFN)-{\gamma}$ production compared with media control (about 2-fold for IL-2, 3-fold for IL-4 and 1.5-fold for $IFN-{\gamma}$, p<0.05) at 24 h. In addition, JSH increased the production of IL-12 on the mouse peritoneal macrophages (by 3.6-fold for IL-12, p<0.05). In conclusion, these data indicate that JSH may have an immune-enhancement effect.

Rubia cordifolia has been used to treat diseases for many years in China and India. Although the biological properties and major compounds of R. cordifolia have been extensively studied, the underlying mechanisms of its biological effects remain elusive. In terms of immunological effects, anti-inflammation effect of macrophage (Raw 264.7) simply has been reported. In this study, R. cordifolia was extracted in 70% ethanol and the extract did not affect to macrophage (Raw 264.7) pro-inflammation and T cell (Molt-4). However, in mast cell (RBL-2H3), it showed inhibition of degranulation. The inducing inhibitory effect on degranulation was related to concentration dependent variation in phosphorylation of ERK-1/2 and upregulating the JNK phosphorylation in RBL-2H3 cells. Based on these data, we concluded that R. cordifolia newly have anti-allergenic effects in RBL-2H3 and might be used as a therapeutic agent to treat or prevent allergic diseases such as asthma and atopic dermatitis.
