The anti-inflammatory effects of an ethanol extract of Angelica gigas (EAG) were investigated in vitro and in vivo using croton oil-induced inflammation models. Croton oil (20 microgram/mL) up-regulated mRNA expression of cyclooxygenase (COX)-I and COX-II in the macrophage cell line, RAW 264.7, resulting in the release of high concentrations of prostaglandin E2 (PGE2). EAG (1~10 microgram/mL) markedly suppressed croton oil-induced COX-II mRNA expression and PGE2 production. Application of croton oil (5% in acetone) to mouse ears caused severe local erythema, edema and vascular leakage, which were significantly attenuated by oral pre-treatment with EAG (50~500 mg/kg). Croton oil dramatically increased blood levels of interleukin (IL)-6 and PGE2 without affecting tumor-necrosis factor (TNF)-alpha and nitric oxide (NO) levels. EAG pre-treatment remarkably lowered IL-6 and PGE2, but did not alter TNF-alpha or NO concentrations. These results indicate that EAG attenuates inflammatory responses in part by blocking the COX-PGE2 pathway. Therefore, EAG could be a promising candidate for the treatment of inflammatory diseases.

In order to explore the rules of combined Chinese and Western medical treatment on immune infertility, the study was carried out by searching relative primary documents from databases and 26 articles (dealing with 5865 cases) were screened out. Excel was used to perform the frequency analysis on the Western drugs and 27 Chinese recipes emerging in the documents separately. It was discovered that the combined use of Chinese and Western medicines has its superiority. Low dose glucocorticoids together with vitamine is the main Western treatment used, and dexamethasone is the most frequently used preparation of glucocorticoids. Among the 72 Chinese drugs presented in the 27 Chinese recipes, 13 appeared for more than 1800 times, they were Angelica sinensis, Salvia miltiorrhiza, Radix Paeoniae Rubra, Radix Astragali, Poria, Carthamus tinctorius, Phellodendron amurense, Scutellaria baicalensis, Anemarrhena asphodeloides, Rehmannia glutinosa, Cuscuta chinensis, Radix Paeoniae Alba and Radix Glycyrrhiza.

OBJECTIVETo study the effect of Angelica sinensis, Salvia miltiorrhiza and Ligustrazine on function of peritoneal macrophages during peritoneal dialysis.

METHODSPeritoneal macrophages of mice were cultured in culture medium (control), peritoneal dialysate (PD), drugs contained PD containing Angelica, Salvia and Ligustrazine combined (PD-ASL) or separated (PD-A, PD-S, PD-L) with concentration of 2 micrograms/ml, 10 micrograms/ml and 100 micrograms/ml, separately for 24 hrs. The nitric oxide (NO) content, methyl thiazolyl tetrazolium (MTT) reducing capacity (MTT-RC) and phagocytosis capacity of macrophages were determined and compared.

RESULTSNO content and MTT-RC of macrophages cultured in PD group were significantly lower than those of the control (P < 0.01), as compared with those in drug contained PD groups, the NO content in the PD-L group and the MTT-RC in the PD-ASL group were higher significantly (P < 0.01). The phagocytosis capacity and NO content in the PD-ASL group were raised along with the increased concentration of drug in PD.

CONCLUSIONAdministering Chinese herbal medicine during peritoneal dialysis has important significance in improving the defense function of peritoneal macrophages, reducing the incidence of peritonitis and enhancing the therapeutic effect of peritoneal dialysis.

To study the chemo-preventive effect of the supercritical extracts from Angelica sinensis (SFE-AS) on induced colorectal carcinoma in mice by using the AOM/DSS-induced male mice colorectal carcinoma model, and discuss its possible action mechanism. Male Balb/c mice were subcutaneously injected with single dose of azoxymethane (AOM, 10 mg x kg(-1) body weight). One week later, they were given 2% dextran sodium sulfate (DSS) in drinking water for 7 days to induce colorectal carcinoma. Each drug group was orally administered with supercritical extracts from Angelica sinensis at 15, 30, 60 mg x kg(-1) until the 17th week. The tumor incidence rate of the SFE-AS group, mice tumor-bearing quantity and tumor-bearing volume of the SFE-AS group were lower than that of the AOM/DSS model control group, which may be related with the significant reduction of PCNA, COX-2, iNOS in the AOM/DSS-induced mouse colorectal carcinoma model associated with inflammation by SFE-AS. According to the results of this study, SFE-AS showed an intervention effect in the incidence and development of AOM/DSS-induced mouse colorectal carcinoma associated with inflammation, and could be further used in chemo-preventive studies on human colorectal carcinoma.

AIMTo study the effect of Angelica sinsensis polysaccharides on lymphocyte proliferation and induction of IFN-gamma.

METHODSAngelica sinensis polysaccharides(AP) were separated into AP-I, AP-II, AP-III and AP-IV by alcohol deposition with different concentration. The radioactivities of [3H]-TdR uptake by lymphocyte were used to determine the ability of lymphocyte. The bioactivity of IFN-gamma was measured by violet crystalline dying.

RESULTSAP-IV was found to be composed of Ara and Glu in the ratio of 0.99:6.47, the molecular weight was estimated to be 5,600. AP-I and AP-II 100 mg.kg-1 i.p. were found to significantly augment mice splenocyte proliferation, release IFN-gamma and increase IFN-gamma bioactivity. 50 micrograms.mL-1 AP-I, AP-II and AP-III were shown to enhance the proliferative response of the mouse spleen lymphocytes in vitro.

CONCLUSIONAP-I and AP-II showed higher immunoactivity than AP-III, AP-IV had no effect.

AIMTo observe the influence of polysaccharides of Angelica sinensis (ASP) on the immunologic function of rat Kupffer cells.

METHODSNormal rat Kupffer cells were treated with ASP in vitro. Absorbance at 540 nm ( A540) of neutral red absorption and supernatant NO, TNF-alpha in the cells were measured to evaluate the immunologic function of Kupffer cells; LDH leakage was measured to estimate the severity of cellular damage; Rats were given ASP 0.025, 0.1, 0.25 and 1.0 g x kg(-1) ig (qd x 7 d) in vivo. The above indices and ACP of Kupffer cells were measured, sGST and sALT activity were detected as indices of hepatotoxicity.

RESULTSASP markedly enhanced the phagocytic activity, ACP and supernatant NO, TNF-alpha of Kupffer cells both in vitro and in vivo . The increase of sGST was observed after administration of ASP 1.0 g x kg(-1), but the LDH leakage of the hepatocytes was not increased in vitro.

CONCLUSIONASP with suitable dose could activate the function of Kupffer cells. Slight liver injury was caused by ASP 1.0 g x kg(-1) in vivo, which was likely caused by factors, such as NO, TNF-alpha, indirectly.

OBJECTIVEThrough establishing different blood deficiency animal model, to evaluate enriching blood effect changes of the drug pair of Angelicae Sinensis Radix and Chuanxiong Rhizoma and each single herb, and to explore the effect characteristics of their compatibility.

METHODThree different methods of acetyl phenylhydrazine (APH) hemolytic method, cyclophosphamide (CTX) chemical damage method, APH-CTX complex method were used respectively to copy different blood deficiency model mice. Changes of orbit blood routine, thymus index, spleen index and ATPase activity of red cell membrane of model mice were tested.

RESULTCompared with normal group, all indexes had significant differences in three model mice. The drug pair and each single herb had significant impact on most indexes of the APH-CTX complex model mice, and on the individual indexes of APH hemolytic model mice and CTX chemical damage model mice. Therefore, APH and CTX complex blood deficiency model was more suitable for the enriching blood mechanism study of the drug pair of Angelicae Sinensis Radix and Chuanxiong Rhizoma. Compared with the single herb of Angelicae Sinensis Radix and Chuanxiong Rhizoma, the drug pair of them had presented enriching blood effect at different extent with strengthening trend in regulating the invigorating blood indexes, immune organs and energy metabolic enzymes.

CONCLUSIONThe results of this research have provided scientific basis for revealing the mutual promotive composition law of the drug pair of Angelicae Sinensis Radix and Chuanxiong Rhizoma, and responded effectively the mult-link and mult-target effect characteristics of Chinese medicine bio-effect, to offer reference for the bio-effect research of the complicated substance group of Chinese medicine and traditional Chinese medicine formulae, and to supply demonstrative reference for researching the formulae compatibility law which takes the single drug-drug pair-formulae as main line.
