We performed this study to determine the effect of Jiegeng(Platycodon grandiflorum), Danggui(Angelica sinensis), Gancao(Glycyrrhiza glabla), Chaihu(Bupleurum falcatnosa), Shoudehuang(Rehmannia glutinosa), Huangqi(Satragalus membranaceus), Muxiang(Saussurea lappa), Yuanzhi(Polygala tenuifolia), Rensen(Panax ginseng) and Baishaoyao(Paeonia lactiflolia), as Oriental radices herbs, on jejunal crypt survival, endogenous spleen colony formation and apoptosis in jejunal crypt cells of mice irradiated with high and low dose of ${\gamma}-radiation$. Jiegeng(p<0.005), Danggui(p<0.0005), Gancao(p<0.005), Chaihu(p<0.05), Muxiang(p<0.05), Rensen(p<0.005) and Baishaoyao(p<0.005) were effective in intestinal crypt survival. Danggui(p<0.05), Chaihu(p<0.05), Shoudehuang(p<0.05), Huangqi(p<0.05), Rensan(p<0.005) and Baishaoyao(p<0.05) increased the formation of endogenous spleen colony. The frequency of radiation induced apoptosis was also reduced by pretreatment with Chaihu(p<0.05), Muxiang(p<0.005), Yuanzhi(p<0.05), Rensan(p<0.05) and Baishaoyao(p<0.05). Although the mechanisms of this effect remain to be elucidated, these results indicated that Danggui, Chaihu, Muxiang, Rensan and Baishaiyao might be a useful radioprotector, especially since it is a relatively nontoxic natural product.

We performed this study to determine the effect of Bu-Zhong-Yi-Qi-Tang, as a prescription of traditional Oriental medicine, and its major ingredients on jejunal crypt survival, endogenous spleen colony formation, apopotosis in jejunal crypt cells, lethality and hematological change of mice irradiated with high and low dose of Y-radiation. Bu-Zhong-Yi-Qi-Tang administration before irradiation protected the jejunal crypts (p<0.0001), increased the formation of endogenous spleen colony (p<0.05) and reduced the frequency of radiation-induced apoptosis (p<0.05). The survival rate and mean survival time of the groups treated with Bu-Zhong-Yi-Qi-Tang within 30 days after the treatment were far better than the irradiation control group. In the experiment on the effect of ingredients of Bu-Zhong-Yi-Qi-Tang, the result indicated that the extract of Rensan (Panax ginseng), Danggui (Angelica sinensis), Shengma (Cimicifuga heracleifolia) and Chaihu (Bupleurum falcatnosa) might have a major radioprotective effect. Although the mechanisms of this inhibitory effect remain to be elucidated, these results indicated that BU-Zhong-Yi-Qi-Tang might be a useful radioprotector, especially since it is a relatively nontoxic natural product. Further studies are needed to characterize better the protective nature of Bu-Zhong-Yi-Qi-Tang extract and its ingredients.

In this study, we evaluated the radioprotective effects of Kuei Pi Tang and its ingredients, as a prescription of traditional Oriental medicine. The jejunal crypt survival, endogenous spleen colony formation, and apoptosis in jejunal crypt cells were investigated in mice irradiated with high and low dose of ${\gamma}$ rays. In the mice administered with Kuei Pi Tang extract before irradiation, the jejunal crypts were protected significantly(p<0.005) and the frequency of radiation induced apoptosis was reduced(p<0.05). In the experiment on the effects of the ingredients of Kuei Pi Tang, the results indicated that the extract of Dangui(Angelica sinensis), Suanzaoren(Zizyphus valgaris), Rensan (Panax ginseng), Fuling(Poria cocos) and Muxiang(Saussurea lappa) might have a major radioprotective effect. Although the mechanisms of this inhibitory effect remain to be elucidated, these results indi cated that Kuei Pi Tang might be a useful radioprotector, especially since it is a relatively nontoxic natural product.

Radiotherapy is an irreplaceable method of cancer treatment. But it has several side effects, especially damages to the hemopoietic and Immune system. Therefore radioprotectors are required to treat cancer successfully. A lot of Herbs and Herbal prescriptions are reported to have radioprotective effects. Above all, those to support the healthy energy and strengthen the body resistance are found more effective. This study was performed to evaluate the radioprotective effects of prescription Shenrong Fuzheng Tang(S.F.T.), which consists of 16 kinds of herbs. We investigated proliferation of murine splenocytes, secretion of colony-stimulating-factors(CSFs), immunocompetence after irradiation in-vitro, and Endogenous spleen colony assay, survival assay in-vivo. When splenocytes were cultured with Shenrong Fuzheng $Tang(S.F.T.)(500{\mu}g/ml)$, proliferation was enhanced 5.7 times compared to control cultured with medium alone(p<0.05) and, showed highest proliferation at 4th day after incubation. In order to evaluate stimulation of hemopoiesis of Shenrong Fuzheng Tang(S.F.T.), the supernatant of splenocytes cultured with optimal concentration of Shenrong Fuzheng Tang(S.F.T.) was used to measure CSFs secretion. The result showed enhanced secretion of colony-stimulating-factors (CSFs) compared to control(p<0.05). To evaluate the protective effect of lymphocytes from irradiation, proliferation of splenocytes stimulated by LPS and ConA after incubation with Shenrong Fuzheng Tang(S.F.T.) for 24h Prior to Irradiation$(1{\sim}3\;Gy)$ was measured. The results showed higher proliferation of Shenrong Fuzheng Tang(S.F.T.) treated cells than that of non-treated cells. And percentage increases of irradiated splenocytes per non-irradiated splenocytes were also higher in Shenrong Fuzheng Tang (S.F.T.)-treated cells than control. Endogenous spleen colony assay. to evaluate the protection of hemopoietic cells from irradiation, showed increased number of colonies(p=0.03) in Shenrong Fuzheng Tang(S.F.T.) treated murine spleen$(10.3{\pm}1.9)$ compared to non-treated murine spleen$(3.4{\pm}0.8)$. Survival time of mice irradiated with lethal dose of ${\gamma}-ray(9Gy)$ was prolonged in Shenrong Fuzheng Tang(S.F.T.) treated group prior to irradiation as compared to non-treated group. According to these results we can suggest that prescription Shenrong Fuzheng Tang(S.F.T.) has radioprotective effects and can be used to protect the hemopoietic and immune system from damages of anti-cancer radiotherapy.

We have examined in vitro and in vivo radioprotective effect of a Chinese medicinal plants prescription, Lifukang. Micronucleus assay was employed to evaluate in vitro radioprotective effect of Lifukang. In the presence of Lifukang, the frequencies of miconuclei were greatly reduced from 7.2 to 2.9, 1.6 and 1.6% at the concentrations of Lifukang from 0 to 2, 10 and $50{\mu}g/ml$, respectively. For in vivo assay, we monitored the incidences of apoptotic cells in mouse small intestine crypts and endogeneous spleen colonies. When Lifukang was administered to mice P.O. Or I.P. at doses of 1 mg/ml in drinking water for 7 days or 0.3 mg/mouse 24 hrs prior to irradiations, respectively, the average numbers of apoptotic cells were reduced to 3.1 or 2.3, respectively, as compared to 4.4 acquired from untreated control experiments. In addition, in spleen colony assay, Lifukang increased the number of hematopoietic spleen colonies. When samples were administered after irradiation, better results were obtained. The numbers of spleen colonies were increased from 14 colonies to 18.3 or 19.6 colonies when Lifukang was given through P.O. (1 mg/ml in drinking water for 11 days) or I.P. (0.3 mg/ mouse) after irradiation, respectively.

This study was performed to determine the toxic effect of DA-3030(granulocyte-colony stimulating factor, G-CSF) in beagle dogs. DA-3030(G-CSF) was injected intravenously at doses of 115 $\mu\textrm{g}$/kg/day, 11.5 $\mu\textrm{g}$/kg/day and 1.15 $\mu\textrm{g}$/kg/day seven days per week for 28 days. After completion of the treatments, the dog were necropsied. The number of dead animal was zero in all groups. No specific clinical sign was found, either. In hematological results, WBC was significantly increased dose-dependently in treated groups. In histopathological findings, megakaryocyte and rubricyte were found in the liver and spleen at the dose of 115 $\mu\textrm{g}$/kg/day. Therefore, we could find the extramedullary hematopoiesis was increased. Megaka yocyte and rubricyte were increased in bone marrow, too. In conclusion, those signs were estimated the pharmacological effect of DA-3030(G-CSF). According to the results, non toxic dose of DA-3030(G-CSF) was higher than 115 $\mu\textrm{g}$/kg/day.

In this study, we carried out the rapid diagnostic system based on indirect fluorescent anti-body technique (IFAT) for detection of bacterial diseases in cultured freshwater fishes. 1. When the fishes were tested with graded dilution of Edwardsiella tarda FPC 470 bacteria detection from ten fishes Injected with $4.1{\times}10^3$colony forming unit(CFU) /ml, all of them were detected by IFAT but only two fishes were recognizable by the culture method in the tested fishes injected with $4.1{\times}10^3$CFU /ml. 2. The bacteria E. tarda could be detected by IFAT method from 1 to 48hrs after Injection in the tissues tested such as kidney, liver and spleen of the fishes, whereas detection by culture method could be recognized from 1 to 48hrs after injection In the kidney and spleen but it was not possible from preinjection to 1 hr in the liver. 3. Thus, IFAT proved to be more useful technique than plate culture method in the diagnosis of Edwardsiellosis in the freshwater fishes.

Objectives: Granulocyte-colony-stimulating factor (G-CSF) mobilized bone marrow (BM)-derived hematopoietic stem cells could contribute to improvement of liver function. In addition, liver fibrosis can reportedly be prevented by the Rg 1 component of red ginseng. This study investigated the combined effect of G-CSF and red ginseng on decompensated liver cirrhosis. Methods: Four patients with decompensated liver cirrhosis were injected with G-CSF to proliferate BM stem cells for 4 days ($5{\mu}g/kg$ bid subcutaneously) and followed-up for 3 months. The patients also received red ginseng for 4 days (2 tablets tid per os). We analyzed Child-Pugh scores, Model for End-Stage Liver Disease (MELD) scores and cirrhotic complications. Results: All patients showed marked increases in White blood cell (WBC) and CD34+ cells in the peripheral blood, with a peak time of 4 days after G-CSF injection. Spleen size also increased after G-CSF injection, but not severely. At end of the study, 2 patients showed improvement in Child-Pugh scores, hepatic encephalopathy, and refractory ascites. During the clinical trial period, none of the 4 patients showed any other adverse events or deterioration of liver function. Conclusions: We conclude that G-CSF/red ginseng combination therapy is relatively effective in improving liver function and major complications of decompensated liver cirrhosis without adverse effects. Further clinical trials are warranted to assess the clinical effects of G-CSF for decompensated liver cirrhosis.

Background: Ginsenoside Re (Re) is one of the major components of Panax ginseng Meyer. Ginsenoside $Rk_3$ ($Rk_3$) is a secondary metabolite of Re. The aim of this study was to investigate and compare the effects and underlying mechanisms of Re and $Rk_3$ on cyclophosphamide-induced myelosuppression. Methods: The mice myelosuppression model was established by intraperitoneal (i.p.) injection of cyclophosphamide. Peripheral blood cells, bone marrow nucleated cells, and colony yield of hematopoietic progenitor cells in vitro were counted. The levels of erythropoietin, thrombopoietin, and granulocyte macrophage colony-stimulating factor in plasma were measured by enzyme-linked immunosorbent assay. Bone marrow cell cycle was performed by flow cytometry. The expression of apoptotic protein bcl-2, bax, and caspase-3 was detected by Western blotting. Results: Both Re and $Rk_3$ could improve peripheral blood cells, bone marrow nucleated cell counts, thymus index, and spleen index. Furthermore, they could enhance the yield of colonies cultured in vitro and make the levels of granulocyte macrophage colony-stimulating factor, erythropoietin, and thrombopoietin normal, reduce the ratio of $G_0/G_1$ phase cells, and increase the proliferation index. Finally, Re and $Rk_3$ could upregulate the expression of bcl-2, whereas they could downregulate the expression of bax and caspase-3. Conclusion: Re and $Rk_3$ could improve the hematopoietic function of myelosuppressed mice. The effect of $Rk_3$ was superior to that of Re at any dose. Regulating the levels of cytokines, promoting cells enter the normal cell cycle, regulating the balance of bcl-2/bax, and inhibiting the expression of caspase-3 may be the effects of Re and $Rk_3$ on myelosuppression.
