Comparative investigations on the protective effects of rhodioside, ciwujianoside-B and astragaloside IV on radiation injuries of the hematopoietic system in mice

The aim of this study was to investigate the protective effects of three glycosides (rhodioside, ciwujianoside‐B and astragaloside IV) on the hematopoietic system in the mice exposed to γ‐rays, and to examine the possible mechanisms involved. Mice were pretreated with the glycosides (40 mg/kg, i.g.) daily for 7 days prior to radiation. The survival of mice pretreated with three glycosides after total body irradiation (6.0 Gy) was examined. Peripheral blood leucocytes and endogenous spleen colony counts, colony‐forming unit‐granulocyte macrophage assay, analysis of DNA content and apoptosis rate determination were performed to evaluate the effects of the three glycosides on hematogenesis. The fragmentation of double‐stranded DNA in lymphocytes was detected by the comet assay. The changes in cell cycle were analysed by flow cytometry. Furthermore, the expression levels of Bcl‐2, Bax and nuclear factor‐kappa B (NF‐κB) were measured by western blot and the electrophoretic mobility shift assay. The results showed that pretreatment with all of the glycosides improved survival time and increased the number of leucocytes, spleen colonies and granulocyte‐macrophage colonies in mice exposed to 6.0 Gy γ‐radiation. Rhodioside showed more protective efficacy than both ciwujianoside‐B and astragaloside IV. All three glycosides significantly increased the proliferation abilities of bone marrow cells, and decreased the ratio of cells in G₀/G₁ phase. Further analysis showed that these three glycosides were able to decrease DNA damage and the increment in the Bax/Bcl‐2 ratio induced by radiation. In summary, the three glycosides showed radioprotective effects on the hematopoietic system in mice, which was associated with changes in the cell cycle, a reduction in DNA damage, and down‐regulation of the ratio of Bax/Bcl‐2 in bone marrow cells exposed to radiation.

Protective Effects of HemoHIM on Immune and Hematopoietic Systems Against γ‐Irradiation

We examined the effect of HemoHIM on the protective efficacy of hematopoietic stem cells and on the recovery of immune cells against sublethal doses of ionizing radiation. Two‐month‐old mice were exposed to γ‐rays at a dose of 8, 6.5, or 5 Gy for a30‐day survival study, endogenous spleen colony formation, or other experiments, respectively. HemoHIM was injected intraperitoneally before and after irradiation. Our results showed that HemoHIM significantly decreased the mortality of sublethally irradiated mice. The HemoHIM administration decreased the apoptosis of bone marrow cells in irradiated mice. On the other hand, HemoHIM increased the formation of endogenous spleen colony in irradiated mice. In irradiated mice, the recovery of total leukocytes in the peripheral blood and lymphocytes in the spleen were enhanced significantly by HemoHIM. Moreover, the function of B cells, T cells, and NK cells regenerated in irradiated mice were significantly improved by the administration of HemoHIM. HemoHIM showed an ideal radioprotector for protecting hematopoietic stem cells and for accelerating the recovery of immune cells. We propose HemoHIM as a beneficial supplement drug during radiotherapy to alleviate adverse radiation‐induced effects for cancer patients. Copyright © 2013 John Wiley & Sons, Ltd.     

Experimental study of the bone marrow protective effect of a traditional Chinese compound preparation

This study investigated the effect of Wei Gan Li on bone marrow haemopoiesis in myelosuppressed anaemic mice induced by ⁶⁰Coγ, cyclophosphamide and chloramphenicol. After treatment with Wei Gan Li, colony forming units of granulocyte macrophages, erythroid cells, burst forming unit‐erythroid cells, megakaryocytes and the proliferation of bone marrow stromal cells were measured by in vitro cell culture techniques. Bone marrow haemopoietic stem cells were measured by flow cytometry. The peripheral blood cell count was found to have significantly recovered after Wei Gan Li administration and the proliferation of bone marrow haemopoietic stem/progenitor cells and BMSC were also significantly increased. Wei Gan Li was therefore found to promote the recovery of bone marrow haemopoietic function in myelosuppressed anaemic mice. Copyright © 2009 John Wiley & Sons, Ltd.

Radioprotective effects of dragon׳s blood and its extracts on radiation-induced myelosuppressive mice

Ethnopharmacological relevance

Dragon?s blood, a traditional Chinese herb, has been used to “panacea of blood activating” and its major biological activity appears to be from phenolic compounds. In this study, our research aims to examine the effects of Dragon?s blood (DB) and its extracts (DBE) on radiation-induced myelosuppressive mice.

Materials and methods

Adult BALB/C mice were exposed to the whole body irradiation with 4 Gy ⁶⁰Co γ-rays. DB and DBE were respectively administered orally for 5 constitutive days prior to irradiation treatment. The radioprotective effects and relevant mechanisms of DB and DBE in radiation-induced bone marrow injury were investigated by ex vivo examination.

Results

We found that the administration of DB and DBE significantly increased the numbers of peripheral blood cells and colony forming unit of bone marrow-derived stem/progenitor cells. Interestingly, compared with the irradiation group, the administration of DB and DBE significantly decreased the levels of the inflammatory cytokines such as IL-6, TNF-α and IFN-γ and oxidative stress injury such as SOD, CAT, GSH, MDA in serum of mice. Furthermore, DBE markedly improved the morphology of bone marrow histopathology.

Conclusions

Our data suggest that DB and DBE effectively attenuate radiation-induced damage in bone marrow, which is likely associated with the anti-oxidative and anti-inflammatory properties of DB and DBE.

Hematopoietic effects and mechanisms of Fufang E׳jiao Jiang on radiotherapy and chemotherapy-induced myelosuppressed mice

Ethnopharmacological relevance

Fufang E?jiao Jiang (FEJ), which has been widely used in clinic to replenish qi (vital energy) and nourish blood, is a famous traditional Chinese medicine formula made up of Colla corii Asini (Donkey-hide gelatin prepared by stewing and concentrating from the hide of Equus asinus Linnaeus.), Radix Codonopsis Pilosulae (the root of Codonopsis pilosula (Franch.) Nannf.), Radix Ginseng Rubra (the steamed and dried root of Panax ginseng C.A. Mey.), Fructus Crataegi (the fruit of Crataegus pinnatifida Bunge) and Radix Rehmanniae Preparata (the steamed and sun dried tuber of Rehmannia glutinosa (Gaertn.) Libosch. ex Fisch. & C.A. Mey.). The present study aimed to investigate the hematopoietic effects of FEJ on myelosuppressed mice induced by radiotherapy and chemotherapy systematically and to explore the underlying hematopoietic regulation mechanisms.

Methods

The myelosuppressed mouse model was induced by ⁶⁰Co radiation, cyclophosphamide and chloramphenicol. FEJ was then administered by i.g. at the dosages of 5, 10, or 20 mL/kg·d for 10 d. The numbers of blood cells from peripheral blood and bone marrow nucleated cells (BMNC) were counted. Body weight and the thymus and spleen indices were also measured. The numbers of hemopoietic progenitor cells and colony-forming unit-fibroblast (CFU-F) were measured in vitro. The ratio of hematopoietic stem cells (HSC) in BMNC, cell cycle and apoptosis of BMNC were determined by flow cytometry. The histology of femoral bone was examined by H&E staining. The levels of transforming growth factor-β (TGF-β), tumor necrosis factor-α (TNF-α), erythropoietin (EPO), granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-3 (IL-3) and interleukin-6 (IL-6) in serum were measured by ELISA. IL-1β, IL-3, IL-6 mRNA levels in spleen were detected by real-time quantitative PCR (RT-qPCR). In addition, bone marrow stromal cells (BMSC) were cultured in vitro followed by treatment with different doses of FEJ (2.5, 5, 10 μL/mL) for 48 h. Then the levels of cytokines (IL-6, SCF, GM-CSF) in the conditioned media and their mRNA levels in BMSC were determined by ELISA and RT-qPCR, respectively.

Results

FEJ could significantly increase the numbers of peripheral blood cells and BMNC, and reverse the loss of body weight and the atrophy of thymus and spleen in a dose-dependent manner. The quantities of hemopoietic progenitor cells and CFU-F in bone marrow were also significantly increased in a dose-dependent manner after FEJ administration. A high-dose FEJ of 20 mL/kg·d could significantly increase the ratio of HSC in BMNC, promote bone marrow cells entering the proliferative cycle phase (S+G₂/M) and prevent cells from proceeding to the apoptotic phase. FEJ could also improve the femoral bone marrow morphology. Furthermore, FEJ could increase the levels of GM-CSF and IL-3 and reduce the level of TGF-β in serum, and enhance the expressions of IL-1β and IL-3 mRNA in spleen. Lastly, the levels of cytokines (IL-6, SCF, GM-CSF) in the conditioned media and their mRNA levels in BMSC were elevated after treatment with FEJ.

Conclusions

FEJ was clearly confirmed to promote the recovery of bone marrow hemopoietic function in a myelosuppressed mouse model, which may be attributed to (i) improving bone marrow hematopoietic microenvironment; (ii) facilitating the cell proliferation and preventing BMNC from apoptosis; (iii) stimulating the expressions of IL-1β, IL-3, IL-6, SCF and GM-CSF and inhibiting the expression of TGF-β.

Preliminary study on antiradiation effect of kuei-pi-tang.

In order to evaluate the potential action of Kuei-Pi-Tang as an antiradiation agent, colony forming units of bone marrow cells in the spleen (CFUs) were used. Different sequences of X-ray irradiation with or without Kuei-Pi-Tang administration in the groups of ICR strain mice were intraperitoneally injected 10mg/20g or 20mg/20g, once a day, for consecutive seven days before or after 4Gy X-ray irradiation. After the different treatments, whole blood was collected from the tail endings to observe the fluctuation of leukocytes, erythrocytes and thrombocytes. The administration of 20mg/20g was more effective than that of 10mg/20g. Lower radiosensitivity was observed with the treatment of 20mg/20g of Kui-Pi-Tang than that of 10mg/20g. The injection of Kuei-Pi-Tang accelerated the recovery of blood cell counts of leukocytes, erythrocytes and thrombocytes in mice irradiated with 4Gy, especially for leukocytes under the treatments with 20mg/20g of Kuei-Pi-Tang administered after irradiation.
