AIM: To evaluate the efficacy of Myelophil, an extract containing Astragali Radix and Salviae Radix, for reducing complications induced by 5-fluorouracil (5-FU) in a gastrointestinal cancer model. METHODS: We injected 5-FU into mice and then administered Myelophil to examine the ability of the drug to treat the side effects of 5-FU in mice. Peripheral blood counts, histological examinations, and colony-forming assays of bone marrow were conducted, followed by swimming tests and assessment of survival times. RESULTS: Myelophil restored red and white blood cells and platelets in blood, and recovered cell density in bone marrow to levels comparable to those observed within the control group. In addition, Myelophil significantly increased colony-forming unit granulocyte-macrophage (CFU-GM) and CFU-erythroid (CFU-E) compared to the control group. We confirmed that interleukin-3 gene expression was upregulated by Myelophil in spleen cells. Myelophil administration also doubled the survival rate of mice that were severely myelosuppressed as a result of 5-FU injection at a lethal dose of 70%. Finally, the swimming performance of mice significantly improved as a result of Myelophil treatment. CONCLUSION: These results provide experimentalevidence in support of clinical applications of Myelophil to minimize 5-FU-induced myelosuppression and improve general post-chemotherapy health.

AIM: To evaluate the pharmaceutical safety of a Chinese herbal formula, Chunggan extract (CGX), traditionally prescribed as a hepatotherapeutic drug via systemic acute and subacute toxicological study. METHODS: Twenty male dogs and 20 female dogs were fed doses 50 times and 4 times greater than the clinically-recommended drug dosages in an acute and a subacute toxicological study, respectively. Adverse effects were examined by comparing the differences between normal and drug-administered groups using clinical signs, necropsies, histopathologic findings, haematology, urinalysis, and biochemical analysis. RESULTS: In the acute study no change in the body weight, diarrhoea, apetite, mortality rate and histopa- thology of major organs was observed in male or female dogs with a single administration of CGX at 5 g/kg. No drug-induced abnormalities at analysis of histopathology, haematology, urinalysis, and biochemistry were found with any dose of this drug. CONCLUSION: CGX is supposed to be very safe when used in a clinical application with a wide therapeutic index.

An herbal formula,CGX,exerts hepatotherapeutic effects on dimethylnitrosamine-induced chronic liver injury model in rats

引用

World Journal of Gastroenterology 2006年第38期12卷 6142-6148页

作者： Jang-Woo Shin Jin-Young son Se-Mi Oh Seung-Hyun Han Jing-Hua Wang Jung-Hyo Cho Chong-kwan Cho Hwa-Seung Yoo Yeon-Weol Lee Myong-Min Lee Xiao Ping Hu Chang-Gue son East-West Cancer Center Dunsan Oriental Hospitalof Orientai medical College of Daejeon University 1136 Dunsan-dong Seo-gu Daejeon 302-122 South Korea Department of Oromaxillofacial Infection and Immunity and Dental Research Institute School of Dentistry Seoul National University 28 Yongon-Dong Chongno-Gu Seoul 110-749 South Korea

AIM: To evaluate the therapeutic effect of Chunggan extract (CGX), a modified traditional Chinese hepatotherapeutic herbal, on the dimethylnitrosamine (DMN)-induced chronic liver injury model in rats. METHODS: Liver injuries were induced in Wistar rats by injection of DMN (ip, 10 mg/mL per kg) for 3 consecutive days per week for 4 wk. The rats were administered with CGX (po, 100 or 200 mg/kg per day) or distilled water as a control daily for 4 wk starting from the 15th d of the DMN treatment. Biochemical parameters (serum albumin, bilirubin, ALP, AST and ALT), lipid peroxides, hydroxyproline, as well as histological changes in liver tissues were analyzed. In addition, gene expression of TNF-α, TGF-b, TIMP-1, TIMP-2, PDGF-b, and MMP-2, all of which are known to be associated with liver fibrosis, were analyzed using real-time PCR. RESULTS: CGX administration restored the spleen weight to normal after having been increased by DMN treatment. Biochemical analysis of the serum demonstrated that CGX significantly decreased the serum level of ALP (P < 0.05), ALT (P < 0.01), and AST (P < 0.01) that had been elevated by DMN treatment. CGX administration moderately lowered lipid peroxide production and markedly lowered hydroxyproline generation caused by DMN treatment in accordance with histopathological examination. DMN treatment induced a highly up-regulated expression of TNF-α, TGF-b, TIMP-1, TIMP-2, PDGF-b, and MMP-2. Of these, the gene expression encoding PDGF-b and MMP-2 was still further enhanced 2 wk after secession of the 4-wk DMN treatment, and was remarkably ameliorated by CGX administration. CONCLUSION: CGX exhibits hepatotherapeutic proper- ties against chronic hepatocellular destruction and consequential liver fibrosis.

Aim:To investigate the inductive effect of water extract from Hericium erinaceum(WEHE)on interleukin-1β(IL-1β)***:A murine macrophagecell-line,RAW 264.7 was stimulated with 1 to 10 mg/L WEHE and inductions of IL-1β protein and its steady state mRNA were examined using a bioassay,Westernblotting,and reverse transcription-polymerase chain reaction(RT-PCR)*** inductive effect of WEHE on IL-1β gene expression was further investigatedby a chloramphenicol acetyltransferase(CAT)reporter gene assay using a tran-sient transfection with pIL-1(870 bp)-CAT where the expression of the CAT genewas regulated by a IL-1β *** electrophoretic mobility shift assay(EMSA)was also performed to examine transcription factors,nuclear factor-kappa B(NF-kB),activator protein 1(AP-1),nuclear factor interleukin-6(NF-IL6),and cAMPresponse element(CRE)/activating transcription factor(ATF).Results:WEHEinduced IL-1β production in both its mRNA and protein expression in a dose-dependent *** inductive effect of WEHE on IL-1β gene expression wasdue to the augmentation of the IL- 1β ***,EMSA showedthat WEHE markedly increased the binding activities of NF-kB,and to a lesserextent,those of AP-1 and NF-IL6 to their cognate DNA recognition sites,whereasCRE/ATF binding remained constant,all of which are known to be involved in theregulation of IL-1β gene ***:WEHE induces IL-1β expres-sion in macrophages at a transcriptional level by enhancing the activation oftranscription factors,NF-kB,NF-IL6,and AP-1.
