Natural products are important sources for drug development because they have a wide variety of useful biological properties. Angelica gigas Nakai (AGN) has been used as an herbal medicine. The present study was designed to evaluate the immune-enhancing effect of AGN in the cyclophosphamide (CP) induced immune-suppressed mice. As the result, we found that CP induced the reductions of body ratio, spleen weights, hematopoietic parameter and cytokine productions in mice. However, AGN recovered immunosuppression-mediated decreased body ratio, spleen and thymus weights as well as regulation of hematopoietic parameter including white blood cell, lymphocyte, and neutrophil. According to histological study, AGN regenerated on CP-mediated injured spleen. Moreover, AGN increased the CP-induced reduction of cytokine expression in spleen tissue. Collectively, the findings provide experimental evidence that AGN may be a candidate for health-improving herbs.

In order to determine the functional benefits of $Cordyceps$ $militaris$ in the immune system, we examined the immunomodulatory activities of $Cordyceps$ $militaris$ in an immunocompromised C57BL/6 mice model. Mice were injected intraperitoneally with an immunosuppressive drug, cyclophosphamide, and then administered orally with 3% hydroxypropylmethylcellulose or 30, 100, and 300 mg/kg of 50% ethanol extract of $Cordyceps$ $militaris$ (CM 30, CM 100, and CM 300, respectively) for 12 days. Mice treated with CM displayed significantly increased splenocyte proliferation and natural killer cell activity compared to immunosuppressed control mice (p<0.05). The spleen cells isolated from mice treated with CM also displayed increased production of Th1 cytokines, including IL-2, IL-12, IFN-${\gamma}$ and TNF-${\alpha}$, suggesting enhanced cellular immunity in response to CM. However, CM had no significant effect on the production of IL-4 and IL-10. These results indicate that $Cordyceps$ $militaris$ enhances immune function by promoting immune cell proliferation and Th1 cytokine production.

This study was investigated the protective effect of Cultivated Wild Ginseng(WG) on the toxicities induced by cyclophosphamide(CP) in mice. Twenty-four male BALB/c mice were divided into non-treated normal group(n=6), CP treated control group(n=6), CP+WG treated CP+WG group(n=6), WG treated WG group(n=6). CP(100 mg/kg of b.w., i.p) was injected at 0, 7 th, 14 th, 21 th, and 28 th day of the experiment respectively. WG(4.4 g/kg, i.p.) was administrated for 35days. Body and organ(heart, liver, kidney, testis) weight were measured. Histopathological examination on the organ(heart, liver, kidney, testis), morphometric analysis, and BrdU immunohistochemistry on the testis were performed. Body weight was decreased following CP administration. In contrast, such a decrease was significantly attenuated by WG administration. CPK and AST of CP+WG group were significantly decreased compared with CP group. Histopathologically, cross sectional area of testis and diameter of seminiferous tubule were significantly increased in CP+WG group compared with CP group. BrdU labelled cells in the seminiferous tubules were remarkably decreased in CP group. Whereas the number of seminiferous tubules labelled with BrdU in spermatogonia was increased by CP+WG administration. The obtained results suggest that WG has protective effect on CP-induced toxicity. This effect might be mediated through the supplementation of vital energy.

The hemopoietic effects of deer blood (whole blood, blood cell, plasma, respectively) were examined using in vivo rat model. Experimental animals (Sprague-Dawley rat, male, 200 g) were divided into negative control group (injection of saline), positive control group (injection of Sipjeondaebotang) experimental groups (injection of whole blood, blood cell, plasma) and healthy control group. Cyclophosphamide(150mg/kg) was injected into experimental groups, negative and positive control group to induce bone marrow supression. After 8 days, freez dried deer blood (whole blood, blood cell, plasma respectively) and Sipjeondaebotang of 200 mg/kg in dose was administered orally into experimental groups and positive control group, once a day for 3 days (A group) and once a day for 12 days (B group) respectively. And then body weight and organ weight, biochemical profile (ALB, GOT, GPT, PRO, CRE), hematological values (WBC, RBC, HGB, HCT, MCV, MCH, MCHC, PLT) and CBC differentiation (Neutro, Lymph, Mono, Reticulo) were carried out. Finally, platelets were specially increased in the plasma treated A group and reticulocytes were specially increased in the plasma treated B group.

Background: Malignant mesothelioma (MM) is almost always fatal and few treatment options are available. The aim of this study was to evaluate the efficacy of oral cyclophosphamide and etoposide for patients who underwent standard treatment for advanced MM. Materials and Methods: This study included 22 malignant pleural mesothelioma patients who were treated with oral cyclophosphamide and etoposide (EE). Results: The average follow-up period of the patients was 39.1 months. Under the treatment of oral EE, median progression-free survival was 7.7 months [95%CI HR (4.3-11.1)] and median overall survival was 28.1 months [95%CI HR (5.8-50.3)]. The treatment response rates were as follows: 4 patients (27.3%) had a partial response (PR), 12 (54.5%) had stable disease (SD), and progressive disease (PD) was observed in 6 (35.9%). Conclusions: Oral EE can be administered effectively to patients with inoperable malignant mesothelioma who had previously received standard treatments.

Background: We compared treatment completion rates and safety of docetaxel and cyclophosphamide sixcycle therapy (TC6) with docetaxel followed by 5FU, epirubicin and cyclophosphamide (T-FEC) therapy in Japanese patients with human epidermal growth factor receptor 2 (HER2)-negative breast cancer. Materials and Methods: We administered TC6 q3w or T-FEC q3w to HER2-negative breast cancer patients. The primary endpoint of this trial was toxicity. As second endpoints, the treatment completion rate and relative dose intensity were evaluated. Results: The TC6 and T-FEC group consisted of 22 and 21 patients, respectively. Concerning hematological toxicity, grade 3 or higher adverse reactions included neutropenia and febrile neutropenia. As non-hematological adverse events, exanthema and peripheral neuropathy were frequently reported in the TC6 group, whereas more patients of the T-FEC group reported nausea and vomiting. In TC6, the treatment completion rate was 86.4% and the relative dose intensity of docetaxel was 93.2%. In T-FEC, the values were 95.2% and 98.9%, respectively. Conclusions: These results suggest that TC6 is tolerable in Japanese, and that this regimen can also be performed in outpatient clinics. However, with the TC6 regimen, the compliance was slightly lower than with the T-FEC regimen, and supportive therapy needs to be managed appropriately.

As an antitumor agents cyclophosphamide (CPA) is frequently used in animal clinic. Important adverse effects of its administration are leukopenia, thrombocytopenia and anemia. We investigated the effects of chicken egg white derivatives (EWD and EF-203) on the changes of blood cells and the neutrophil phagocytosis of rats administered with CPA. Rats were administered CPA peritoneally at dose of 50 mgag once a day far 3 days plus either EWD or EF-203 orally at dose of 200 mg/kg once a day far 3 days. Thereafterl the changes of blood cells by automatic blood cell counter and the phagocytosis of neutrophils by flow cytometry were examined far 7 days. There was no change in RBC values regardless of administration of either EWD or EF-203 throughout experimental period. But rats receiving CPA plus either EWD or EF-203 showed a significant higher PCV values than those of CPA alone (p<0.01). The numbers of peripheral blood platelets and WBC and the differential count of neutrophils in the ra% receiving CPA plus either EWD or EF-203 were significantly higher (p<0.05 to 0.01) than those of CPA alone. Moreover, these rats showed significanly enhanced phagocytoses of neutrophils when compared to rats with CPA alone (p<0.01). These result suggested that chicken egg white derivatives including EWD and EF-2% have immunomodulatory effects in regard to the increase of platelets, WBC, differential count of neutrophils, PCV, and the enhancement of phagocytic activity of neutrophils in immunosuppressed rats by CPA. Thus, co-adminstration of chicken egg white derivatives will be able to reduce the side effects in the animals treated with antitumor agents.

Zingiberis rhizoma(ZB) has been used to treat a various condition and disease in many traditional preparation. The present study was conducted to investigate the immunomodulatory effect on cyclophosphamide(CY)-induced immunotoxicity of aqueous-extracted ZB(ZBE) using in vitro and in vivo experiment. In vitro experiment, the mouse spleen cells proliferation and nitric oxide(NO) production in RAW 264.7 mouse macrophage cells were investigated. ZBE enhanced mitogenic activity in mouse spleen cells. The suppression of CY-induced mouse speen cell proliferation was significantly restored by ZBE treatment. ZBE inhibited NO production, iNOS mRNA and protein levels in LPS-stimulated RAW 264.7 cells. In vivo experiment, ZBE was orally administrated(single dose of 150mg/kg for 12 days) and CY i.p(150mg/kg) injected to SD rats. In CY alone injected group, body weights and spleen weights, and a various hematological parameters were reduced when compared with control group, whereas those values were increased by concomitant treatment of CY and ZBE when compared with CY alone injected group. These results indicated that ZBE can modulate CY-induced immune suppression through immune cell proliferation, the regulation of NO production and the inhibition of CY-induced immunotoxicity.
