Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Brazil, latex of Himatanthus drasticus is used to treat inflammation, wound healing and cancer. The present study evaluated the antitumoral potential of H. drasticus latex (HdCL) in Sarcoma 180-bearing mice (S180). MATERIALS AND METHODS HdCL was obtained in Crato-CE, Brazil. Qualitative phytochemicals assays, nuclear magnetic resonance (NMR) and microbiological analyzes were performed. Swiss mice were divided into six groups, according to tumor forms: 1) ascitic model, GI (Control; 0.9% saline), GII (S180asc) and GIII (S180asc/HdCL/14 days); 2) solid model, GIV (Control; 0.9% saline), GV (S180sol) and GVI (S180sol/HdCL/10 days). HdCL and 0.9% saline were administered at 0.2 mL, SID, by gavage, for 10 or 14 days. For ascitic model, 0.5 mL of S180 suspension (4×106 cells/mL) was inoculated intraperitoneally and for solid model, cells were inoculated subcutaneously (25 µL) on the right hind paw of mice. Blood samples were collected for hematological and oxidative stress evaluation. Thickness, volume and weight of paws were measured in solid model. After euthanasia, spleen, liver and kidney were collected in order to assess the relative organ weight. Tissue fragments of paws and popliteal lymph nodes (PLN) were analyzed by H&E and CD4+, CD8+, HSP-60+ and Foxp3+ immunohistochemistry. RESULTS HdCL presented milky aspect and pinkish supernatant. Phenols, flavonols, flavanones, free steroids and cinnamoyl derivatives of lupeol, α-amyrin and β-amyrin were detected at the phytochemistry analysis. HdCL did not alter the relative weight of organs, hematological parameters and volume of ascitic fluid recovered. In solid model, HdCL reduced (P < 0.05) paw volume, but did not altered thickness, paw weight and histological parameters. S180sol induced necrosis, metastasis and destruction of bone, cartilage and muscles. Bleeding, vessel congestion and oncocytes were observed in PLN. In paw, HdCL did not alter FoxP3+ and HSP-60+ expressions but reduced the CD4+ and CD8+ expressions, while at PLN, HdCL reduced the expressions of all markers. HdCL decreased (P < 0.05) serum levels of malondialdehyde in ascitic model. CONCLUSIONS Treatment with HdCL reduced oxidative damage and modulated the expressions of CD4+, CD8+, FoxP3+and HSP-60+ in S180 solid tumor model, which can be associated to the presence of triterpenes, such as α-amyrin, β-amyrin and lupeol cinnamate. Present data emphasizes the importance of immune system in cancer and highlights the evaluation of the pharmacological properties of plants used by population as phytoterapics.

Abstract
UNLABELLED Abstract Context: Most of the present studies on the antitumor efficiency of Cymbopogon citratus (DC.) Stapf (Gramineae) are limited to its low-mass compounds, and little information about the antitumor activity of polysaccharides from this plant is available. OBJECTIVES This study focused on the potential antitumor and immunomodulatory activities of polysaccharides (CCPS) from C. citratus. MATERIALS AND METHODS CCPS was isolated using the water extraction-ethanol precipitation method. The sarcoma 180 (S180) cells-inoculated mice were intraperitoneally administrated with CCPS (30-200 mg/kg/d) for seven consecutive days. The effects of CCPS on tumor growth, thymus and spleen weights, splenocyte proliferation, and cytokine secretion in the tumor-bearing mice were measured. The cytotoxicity of CCPS (50-800 μg/mL) towards S180 cells was also studied. RESULTS CCPS significantly inhibited the growth of the transplanted S180 tumors, with the inhibition rates ranging from 14.8 to 37.8%. Simultaneously, CCPS dose-dependently improved the immunity of the tumor-bearing mice. With the highest dose of 200 mg/kg/d, the thymus and spleen indices were increased by 21.9 and 91.9%, respectively; ConA- and LSP-induced splenocyte proliferations were increased by 32.7 and 35.3%, respectively. The secretions of interleukin 2 (IL-2), interleukin 6 (IL-6), interleukin 2 (IL-12), and tumor necrosis factor-α (TNF-α) were increased by 103.2, 40.2, 23.6, and 26.3%, respectively. Nevertheless, almost no toxicity of CCPS towards S180 cells was observed, with the maximal inhibition rate less than 15% at the CCPS concentration of 800 μg/mL. CONCLUSION CCPS exhibited antitumor activity in vivo, and this activity might be achieved by immunoenhancement rather than direct cytotoxicity.

Abstract
AIM To induce cancer resistance in wild-type mice and detect if the resistance could be inherited to the progeny of the induced resistant mice. Furthermore to investigate the spectrum and immunology of this inherited cancer resistance. MATERIALS AND METHODS Resistance to with live S180 cancer cells in BALB/c mice was induced by immunization with inactivated S180 cancer cells. The immunization was performed by either frozen/thawed or irradiated cancer cells or cell-free ascitic fluid (CFAF). RESULTS In all instances the induced resistance was demonstrated to be inheritable. The phenotype was named HICR (heritable induced cancer resistance) and was defined as primary resistant progeny from mice immunized with frozen/thawed or irradiated S180 cells or CFAF obtained from mice with S180 induced ascites. Notably, this resistance was transferred from both male and female mice to the offspring of the immunized mice for at least two generations. Although inheritable, the frequency of cancer-resistant pups was lost over a few generations. Cells from the J774A.1 and RAW cancer cell lines did not induce inheritable cancer resistance, and C57BL/6 mice could not pass on cancer resistance fluorescence-activated cell sorting (FACS) analyses of the peritoneal cells revealed an increased fraction of macrophages. In necropsies of resistant mice no histological signs of cancer or other disease was found. CONCLUSION Only materials derived from S180 cells could give rise to HICR mice. The molecular basis of the resistance is unknown but may involve epigenetic mechanisms. Other examples of inheritability of acquired phenotypic changes exist but, to our knowledge, this is the first demonstration of acquired, inherited cancer resistance.

Abstract
We previously reported that the mutant virus of HSV (mtHSV) mediated tumor therapy was efficacious in Balb/c and nude mice. However, it is significant to know whether mtHSV works in HSV-1 tumor seropositive individuals because many patients with HSV-1 seropositivity have been found in clinical trial. Here we asked whether the oncolytic effect of mtHSV is influenced under condition of HSV-1 seropositivity. In this study, Balb/c mice were immunized intraperitoneally with mtHSV and HSV-1 F. Subsequently, HSV seropositive and naive Balb/c mice were inoculated with sarcoma 180 cells in the armpit of left forelimb and then were treated with mtHSV intratumorally. The results shown that the growth of tumor in HSV-1 F seropositive mice was inhibited dramatically after treatment with mtHSV; and significant differences in mean tumor growth ratio were found compared with the groups of mtHSV seropositive mice and naive mice. These data demonstrated that the effect of mtHSV-mediated tumor therapy couldn't be weaken but enhanced by HSV seropositivity. Furthermore, comparison of in vitro cytotoxicity to S-180 cells of PBMC from HSV seropositive and naive mice showed PBMC from HSV-1 F seropositive had the highest killing percentage. Cytokines transcription level of PBMC showed IFNgamma were enhanced remarkably in early and late infection stage in HSV seropositive mice, which implied that it could be an important factor to inhibit the tumor growth or eliminate the tumor directly.

Abstract
We investigated the anti-tumor effects of a dry powder preparation of the antlered form of Ganoderma lucidum (G. lucidum AF, rokkaku-reishi in Japanese), a variant type of G. lucidum, not only in allogeneic Sarcoma 180-bearing ddY mice, but also in syngeneic MM 46-bearing C3H/He mice. G. lucidum AF inhibited tumor growth and elongated the life span when orally administered to mice by free-feeding of a 2.5% G. lucidum AF-containing diet. It also showed anti-tumor activity in spite of post-feeding after tumor inoculation. G. lucidum AF significantly countered the depression of splenic CD8+ cells and protected the decrease in interferon-gamma (IFN-gamma) production in regional lymph nodes of MM 46-bearing mice, indicating that the anti-tumor activity of G. lucidum AF might be caused by its immunostimulating action. These results suggest that the ingestion of G. lucidum AF can be useful for the prevention and curing of cancer.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The larvae of Musca domestica (Diptera: Muscidae) have been used traditionally for malnutritional stagnation, decubital necrosis, osteomyelitis, ecthyma and lip scald and also to treat coma and gastric cancer in the traditional Chinese medicine. Its in vitro antitumor activity and immunomodulatory effect in naïve mice in relation to the traditional uses were also reported. However, the in vivo antitumor effect of this insect and its mechanism of action have not yet been well studied. The objectives of this study were to evaluate the in vivo antitumor potential of the peptide fraction from Musca domestica larvae (MDPF) and to elucidate its immunological mechanisms. MATERIALS AND METHODS The mice inoculated with sarcoma S180 cells were orally administered with MDPF at three doses for 10 days. The effects of MDPF on the growth of mouse S180 sarcoma, splenocyte proliferation, the activity of natural killer (NK) cells and cytotoxic T lymphocytes (CTLs), production and mRNA expression of cytokines from splenocytes, and serum antigen-specific antibody levels in tumor-bearing mice were measured. RESULTS MDPF could significantly not only inhibit the growth of mouse transplanted S180 sarcoma, but also promote splenocytes proliferation, NK cell and CTL activity from splenocytes, and enhance serum antigen-specific IgG, IgG2a and IgG2b antibody levels in S180-bearing mice. MDPF also significantly promoted the production of IFN-γ and up-regulated the mRNA expression levels of IFN-γ and Th1 transcription factors T-bet and STAT-4 in splenocytes from the S180-bearing mice. However, Th2 cytokine IL-10 and transcription factors GATA-3 and STAT-6 were not significantly changed both at transcriptional and protein levels following MDPF treatment. CONCLUSIONS MDPF significantly inhibit the growth of transplantable tumor in mice and its in vivo antitumor activity might be achieved by switching-on of Th1-based protective cell-mediated immunity. MDPF could act as antitumor agent with immunomodulatory activity.

Abstract
We evaluated the antitumor activity of crude extract and ascophyllan prepared from Ascophyllum nodosum in sarcoma-180 solid tumor-bearing mice with continuous intraperitoneal (i.p.) administration at a dose of 50 mg/kg body weight/day or oral administration at a dose of 500 mg/kg body weight/day. Ascophyllan and crude extract administered via the oral route showed greater antitumor effects than via i.p. route, and the tumor sizes in mice treated with ascopyllan and crude extract were reduced by a mean of 68.7±6.8% and 42.4±24.8% by the oral route, and 41.4±16.1% and 13.6±20.6% by i.p. route compared to control mice. Splenic natural killer cell activity in the mice treated with ascophyllan and crude extract by i.p. route was significantly enhanced, while only a slight increase of this activity was observed in orally-treated mice. Furthermore, increase in spleen weight of tumor-bearing mice was slightly suppressed by oral administration of ascophyllan, whereas i.p. administration resulted in further enlargement. Analysis of serum cytokines revealed that oral treatment with ascophyllan resulted in significant increase of tumor necrosis factor-α and interleukin-12 levels. Since ascophyllan showed no direct cytotoxic effect on sarcoma-180 cells, orally-administered ascophyllan is suggested to exhibit its antitumor activity through the activation of the host immune system.

Abstract
Solasodine rhamnosyl glycosides (SRGs) induce apoptosis in a wide variety of cancer cells and are more effective than many well-established anticancer agents. Combination therapy of SRGs with cisplatin treats cisplatin-resistant cells such as lung cancer and breast cancer cells. Anticancer therapies with SRGs have been used intravenously, intraperitoneally, intralesionally, orally, and topically. Data is now presented that in addition to apoptosis and, perhaps as a consequence thereof, SRGs also have an effect of stimulating lasting immunity against cancer as shown with a mouse model and the terminal cancer Sarcoma 180. Mice were inoculated i. p. with Sarcoma 180. Groups of animals were administered SRGs half an hour after Sarcoma 180 inoculation. Mice treated with Sarcoma 180 but not with SRGs all died within 20 days. Four doses of SRGs caused total remission of Sarcoma 180 activity. Mice that went into remission were then reinoculated 20 days later with the cancer. Ten of twelve SRGs cured-animals were resistant to reinduction of terminal doses of the cancer. In comparison, twelve of twelve mice treated with SRGs without initial Sarcoma 180 activity but which were inoculated with Sarcoma 180 cells 20 days later, all died. In addition to apoptosis, SRGs stimulate lasting immunity against cancer. SRGs could play an important role in clinical management of diseases such a malignancy and also be used as a preventative therapy.

Abstract
Oyster extracts have been reported to have many bioactive peptides. But the function of oyster peptides produced by proteolysis is still unknown. In this study, the oligopeptide-enriched hydrolysates from oyster (Crassostrea gigas) were produced using the protease from Bacillus sp. SM98011 at laboratory level, and scaled up to pilot (100 L) and plant (1,000 L) levels with the same conditions. And the antitumor activity and immunostimulating effects of the oyster hydrolysates in BALB/c mice were investigated. The growth of transplantable sarcoma-S180 was obviously inhibited in a dose-dependent manner in BALB/c mice given the oyster hydrolysates. Mice receiving 0.25, 0.5 and 1 mg/g of body weight by oral gavage had 6.8%, 30.6% and 48% less tumor growth, respectively. Concurrently, the weight coefficients of the thymus and the spleen, the activity of natural killer (NK) cells, the spleen proliferation of lymphocytes and the phagocytic rate of macrophages in S180-bearing mice significantly increased after administration of the oyster hydrolysates. These results demonstrated that oyster hydrolysates produced strong immunostimulating effects in mice, which might result in its antitumor activity. The antitumor and immunostimulating effects of oyster hydrolysates prepared in this study reveal its potential for tumor therapy and as a dietary supplement with immunostimulatory activity.

Abstract
BACKGROUND High-intensity focused ultrasound (HIFU) therapy offers great promise for the treatment of cancer. The histological changes, including the antitumor immunological response, after HIFU treatment was examined in soft tissue sarcoma. MATERIALS AND METHODS Sarcoma 180 cells were injected subcutaneously in mice. Approximately 2 weeks after the injection, the tumor was irradiated by a single shot of HIFU. The tumor diameter was measured and the survival rate was observed after treatment. The tumors were resected, and stained with TUNEL stain, tartrate-resistant acid phosphatase (TRAP) stain to detect tumor-associated macrophages, and immunohistochemical stains for CD4 and CD8. RESULTS The tumor size in the HIFU group was significantly smaller than the control and survival rate was significantly higher. The numbers of TUNEL-, TRAP-, CD4- and CD8-positive cells infiltrating the tumor were significantly higher in the HIFU group. CONCLUSION HIFU, even when administered as a single shot, induces apoptosis of tumor cells and intratumoral infiltration of macrophages and lymphocytes.

Abstract
OBJECTIVE To investigate the therapeutic effect of sequential intratumoral injection of xenogeneic antigens in immunized tumor-bearing mice. METHODS Sequential intratumoral injection of the xenoantigens was performed in immunized mice bearing S180 tumor. The tumor size changes were observed, and the tumor-infiltrating lymphocytes (TIL) including CD3+CD4+T, CD3+CD8+T, and CD3+CD4+CD25+T lymphocytes were counted with flow cytometry. The concentrations of IL-2 and TNF-alpha in the tumor was measured using ELISA. RESULTS No significant difference was found in the number of CD3+T lymphocytes in the TILs between different groups. After the immunotherapy, the percentages of CD3+CD4+T, CD3+CD8+T and CD3+CD4+CD25+T lymphocytes were 54%, 22% and 2.91%, respectively, with the CD4+/CD8+ ratio of 2.49, significantly different from that in the control group (P<0.05). The concentrations of IL-2 and TNF-alpha were 100.61 pg/ml and 54.114 pg/ml, respectively, significantly different from those in the control group (P<0.05). CONCLUSION Sequential intratumoral injection of heteragenetic antigena can significantly increase the amount of effector cells and cytokines in the micro-environment of the tumor, and decrease the expression of T regulatory.

Abstract
AIM To develop a rationally designed new organotin compound namely dimethyl tin 4-cyclohexyl thiosemicarbazone (D4-t) and evaluate its putative antitumor activity. METHODS Starting from 4-cyclohexyl thiosemicarbazone, a three step synthetic procedure was followed to obtain the title compound. In vivo lymphocyte activation property of the compound at three different doses was assayed by measuring the blastogenesis. Concanavalin A (ConA) was used as standard mitogen for murine T cells stimulation in vivo . Also, the synthesis of DNA by the activated lymphocytes was measured after injecting the D4-t. The lymphocyte activation property and antitumor efficacy of D4-t were assessed in Sarcoma-180 (S-180) bearing mice. The organization of lymphoid cells was studied in the histological preparations of spleen and mesenteric lymph node. Tumor neutralization assay (Winn assay) was conducted to examine whether immune responses were associated with the manifestation of antitumor efficacies of this compound in S-180 in vivo . The DNA synthesis inhibitory effect of the compound in S-180 cells was studied in vitro, and was found significant (P < 0.001). RESULTS Different doses of the new compound caused differential response of blastogenesis and DNA synthesis. In comparison to ConA, the title compound showed a good number of blast cells at its optimum dose of 5 mg/kg. It caused maximum synthesis of DNA by the lymphoid cells. In histological preparations, the gradual transformation of lymphocytes into blasts was observed without any visible toxicity. Winn assay revealed that 5 mg/kg of D4-t was able to reduce tumor mass without severe toxicity. This organotin compound also inhibits the synthesis of DNA in S-180 tumor cells in comparison to Platin10 and ConA. CONCLUSION The title compound has the lymphocyte activation property and stimulates immune response of the lymphoid cells, which in turn express the antitumor activity without any significant toxicity. Results indicate promising therapeutic potential of D4-t.

Abstract
OBJECTIVE To explore the effect of Potrinia scabro extracts (PSE) on the level of serum cytokine in Sarcoma 180 ascitic tumor burdened mice and its mechanism of anti-tumor. METHODS The mice model of Sarcoma 180 ascitic tumor were established and divided into five groups randomly, including the model group with normal saline solution, the positive group with 10 mg/kg cytoxan and PSE treated groups at doses of 2.0 g/kg, 1.0 g/kg, 0.5 g/kg intraperitoneally for 10 days. The level of serum cytokine Th1 (IL-2, IL-12, IFN-gamma, IFN-alpha) and Th2 (IL-6, IL-10) were measured by double antibody sandwich ELISA assay. RESULTS Compared with model group of Sarcoma 180 ascitic tumor burdened mice,the level of IL-2 and IFN-gamma increased in PSE 2.0 g/kg group, but the IL-6 and IL-10 decreased in PSE 2.0 g/kg and 1.0 mg/kg groups. CONCLUSION PSE has anti-tumor effect in vivo that could be related to the level variation of IL-2, IFN-gamma, IL-6 and IL-10 in tumor burdened mice.

Abstract
OBJECTIVE To study the erythrocyte immuno-regulatory effect of Patrinia scabra Bunge extracts extracted by macroporous adsorptive resins in tumor bearing mice. METHODS Patrinia scabra Bunge was extracted by macroporous adsorptive resins, and the amount of polysaccharides and saponins in the extract were determined. Mice bearing S180 tumor were treated with the extract and their survival prolongation rate, erythrocyte rosette formation rates of C3b receptor (ERR-CR), immune complex (ERR-IC) and tumor cell (ERR-TC), as well as the CD35 and CD44s were observed. RESULTS Polysaccharide content was 21.4%, saponin 41.8% in the extract. As compared with the model group, the survival rate was increased, the erythrocyte immune function was improved (showed increase of ERR-CR and ERR-TC, decrease of ERR-IC), and the amount of CD35 and CD44s in red blood cell membrane increased in mice after being treated with the extract (P < 0.05 or P < 0.01). CONCLUSION Extract of Patrinia scabra Bunge extracted by macroporous adsorptive resins can regulate the erythrocyte immune function to a certain extent.

Abstract
The polysaccharide LBPP was extracted and isolated from the pollen of brassica napus L., and the antitumor activity was evaluated on Sarcoma 180-bearing mice and B16 melanoma-bearing mice through transplantable animal tumor. Mice were treated with three doses of the polysaccharide LBPP (50, 100 and 200 mg/kg body weight) for 10 days. Tumor weight, relative spleen and thymus weight, lymphocyte proliferation, natural killer cell activity, delayed type hypersensitivity (DTH), phagocytic function of monocyte, serum hemolysis antibody and peripheral blood of tumor-bearing mice were studied. At the doses of 100 and 200 mg/kg, a significant decrease (P<0.01) in tumor formation, a significant increase (P<0.05) in relative spleen and thymus weight, natural killer cell activity, phagocytic function of monocyte, lymphocyte proliferation, and serum hemolysis antibody, and a significant improvement of peripheral blood abnormality (P<0.05) and anemia (P<0.01) were observed. Results of these studies demonstrated that the polysaccharide LBPP had anti-tumor activity, which was mediated by immunomodulation and leukogenic and antianemic actions.

Abstract
The modulation of carrageenan oligosaccharides from Kappaphycus striatum on the immune system in S180-bearing mice was investigated. The mice inoculated with S180 cell suspension were treated p.o. with carrageenan oligosaccharides (50, 100 and 200 microg/g) for 14 days. The effects of carrageenan oligosaccharides on transplantable tumors and macrophage phagocytosis, quantitative hemolysis of sheep red blood cells (QHS), lymphocyte proliferation, the activity of natural killer cells (NK), production of interleukin-2 (IL-2) and tumor necrosis factor-alpha (TNF-alpha) were studied. Carrageenan oligosaccharides could significantly inhibit the growth of transplantable sarcoma S180 and increase macrophage phagocytosis, the form of antibody secreted by spleen cells, spleen lymphocyte proliferation, NK cells activity, serumal IL-2 and TNF-alpha level in S180-bearing mice. Considering all these results, it is suggested that carrageenan oligosaccharides exert their antitumor effect by promoting the immune system.

Abstract
Calcineurin (CN) is a Ca (2+)/calmodulin-stimulated protein phosphatase. It is a heterodimeric enzyme consisting of a catalytic subunit (CN A) and a Ca2+ -binding regulatory subunit (CN B), which plays an important role in the human immune system. Its regulatory subunit, CN B, on its own, was found to have a remarkable anticancer effect in mice. To clarify the basis of this action the in vivo and in vitro effect of CN B on several types of mice immunocytes was investigated. The phagocytic activity of peritoneal macrophages of both normal mice and mice bearing S 180 solid tumors increased when CN B was injected daily. In vitro examination using a modified MTT assay and an [3H] incorporation assay showed that the cytotoxicity of peritoneal macrophages was increased substantially. CN B also increased the natural killer activity of murine spleen lymphocytes in vivo and in vitro, and synergized with concanavalin A in stimulating their proliferation. Our results indicate that CN B has a significant stimulatory action on the immune system that may partially account for its anticancer activity.

Abstract
Pleurotus ostreatus is one of the widely cultivated edible mushrooms. Water-soluble proteoglycan fractions from P. ostreatus mycelia were purified by alcohol-precipitation, ion exchange and followed by gel permeation (Sephadex G-100) chromatography. Three neutral fractions were found, which had polysaccharide to protein ratios 14.2, 26.4 and 18.3, respectively. These fractions were tested for in vitro and in vivo immunomodulatory and anticancer effects on Sarcoma-180-bearing mouse model. In vivo injection of proteoglycans to Sarcoma-180-bearing mice decreased the number of tumor cells and cell cycle analysis showed that most of the cells were found to be arrested in pre-G(0)/G(1) phase of cell cycle. All of the three proteoglycans elevated mouse natural killer (NK) cell cytotoxicity and stimulated macrophages to produce nitric oxide. The Fourier transform infra red (FTIR) spectra suggested the presence of beta-glycosidic bond in all the fractions. Fraction I strongly interacted with glucose/mannose-specific lectin Concanavalin A (ConA), indicating the presence of large number of terminal sugar with glucose/mannose. Thus, the three neutral proteoglycans derived from the mushroom (P. ostreatus) mycelia could be used as immunomodulators and anti cancer agents.

Abstract
Polysaccharides isolated from the gel of Aloe species have been known to have diverse biological activities, including immunomodulatory and antitumor activities. The molecular size-immunomodulatory activity relationship of modified Aloe polysaccharide (MAP) was examined in this study. Crude MAP (G2E1) was prepared from the gel of Aloe vera that was partially digested with cellulase. Proteins in crude MAP were removed by passage through a DEAE-Sephacel column, and then the protein-free MAP (G2E1D) was further separated into three fractions, G2E1DS3 molecular weight (MW > or = 400 KDa), G2E1DS2 (5 KDa < or = MW < or = 400 KDa), G2E1DS1 (MW < or = 5 KDa), by Sephacryl column chromatography and ultrafiltration. Immunomodulatory activities of MAP preparations were examined on a mouse macrophage cell line, RAW 264.7 cells, and in ICR strain of mouse implanted with sarcoma 180 cells. We found that polysaccharides between 400 and 5 KDa exhibit the most potent macrophage-activating activity as determined by increased cytokine production, nitric oxide release, expression of surface molecules, and phagocytic activity. In accordance with the in vitro activity, polysaccharides between 400 and 5 KDa also exhibited the most potent antitumor activity in vivo.

Abstract
The modulation of a polysaccharide-protein complex from Lycium barbarum (LBP3p) on the immune system in S180-bearing mice was investigated. The mice inoculated with S180 cell suspension were treated p.o. with LBP3p (5, 10 and 20 mg/kg) for 10 days. The effects of LBP3p on transplantable tumors and macrophage phagocytosis, quantitative hemolysis of sheep red blood cells (QHS), lymphocyte proliferation, the activity of cytotoxic T lymphocyte (CTL), interleukin-2 (IL-2) gene expression and lipid peroxidation were studied. LBP3p could significantly inhibit the growth of transplantable sarcoma S180 and increase macrophage phagocytosis, the form of antibody secreted by spleen cells, spleen lymphocyte proliferation, CTL activity, IL-2 mRNA expression level and reduce the lipid peroxidation in S180-bearing mice. The effect is not dose-dependent in a linear fashion. A total of 10 mg/kg dose is more effective than 5 and 20 mg/kg doses. This suggests that LBP3p at 10 mg/kg has a highly significant effect on tumor weight and improves the immune system.

Abstract
Canova is a homeopathic complex medicine, used as an immune modulator. We studied its effects in normal and sarcoma 180-bearing mice. Three control groups were also evaluated. The mice were examined at daily intervals and the tumours observed histologically. Peripheral blood was analysed by flow cytometry. A delay in the development, and a reduction in size of the tumours, and increased infiltration by lymphoid cells, granulation tissue, and fibrosis surrounding the tumour were observed with active treatment compared to control. All animals from the treated group survived, 30% of control groups died. In 30% of treated animals, a total regression of the tumour was confirmed using light microscopy, no regression was found in the control groups. Treatment with Canova increased total numbers of leukocytes and lymphocytes. Among lymphocytes, TCD4, increased in normal-treated group and B and NK cells in S180-treated groups. The results reflect enhanced immune response of the host after treatment with Canova.

Abstract
The polysaccharide L-II was isolated and purified from the fruiting body of Lentinus edodes, which consisted of d-glucopyranose and had the molecular weight of 2.03 x 10(5) Da. We evaluated the effects of the polysaccharide L-II on the cellular immune response of Sarcoma 180-bearing mice. Mice were treated with three doses of the polysaccharide L-II (1, 5, and 10 mg/kg body weight) for 10 days. Tumor weight, relative spleen and thymus weight, delayed-type hypersensitivity (DTH) response, phagocytosis of macrophage, splenocytes proliferation were studied. Concentration of tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma) and interleukin-2 (IL-2) in mice serum were measured in control and polysaccharide groups. At the dose of 1, 5 and 10 mg/kg, a significant increase (p<0.05) in relative spleen and thymus weight, DTH, phagocytosis of macrophage was observed, as well as a significant decrease in tumor formation. The concentration of TNF-alpha, IFN-gamma in serum increased significantly in the polysaccharide groups compared with the model control group, but IL-2 not. Moreover, the polysaccharide L-II could increase NO production and catalase activity in macrophages. Results of these studies demonstrated the antitumor activity of the polysaccharide L-II on mice-transplanted sarcoma 180 was mediated by immunomodulation in inducing T-cells and macrophage-dependent immune system responses.

Abstract
OBJECTIVE To study the anti-tumor and immunological effect of extracts from Thymus quinquecostatus Celak on mice transplanted S180 tumor cells. METHODS Different doses of volatile oil and alcohol extracted substances from Thymus quinquecostatus Celak were given to mice bearing S180 tumor for 9 days. Tumor inhibition rates and coefficients of spleen and thymus were determined. RESULTS Tumor inhibition rates of the groups with alcohol extracts (40 g crude drug.kg(-1).d(-1) and 20 g crude drug.kg(-1).d(-1)) were 51.5% (P<0.01) and 36.4% (P<0.05) respectively, and those of the groups with volatile oil (40 g crude drug.kg(-1).d(-1) and 20 g crude drug.kg(-1).d(-1))were both 39.4% (P<0.05). CONCLUSION The extracts from Thymus quinquecostatus Celak have anti-tumor activities. The coefficient of spleen in group with alcohol extracts (40 g crude drug.kg(-1).d(-1))was close to normal value, and its coefficient of thymus was between that of the negative control group and the group with cyclophosphamide (0.02 g.kg(-1).d(-1)). The anti-tumor activity of the alcohol extracts was significantly higher than that of the control group and the tumor inhibition rate was depending on drug concentration. Depending on index of immunity,the extracts from Thymus quinquecostatus Celak may have some influences on immunity.

Abstract
Tumor-bearing mice showed a significant resistance against Candida albicans intravenous infection. Longer survival was observed in groups of mice inoculated with fungal cells 2-3 weeks after tumor transplantation with allogeneic sarcoma 180, syngeneic methylcholanthrene-induced Meth A fibrosarcoma, and MM 46 mammary carcinoma than in non-tumor-bearing mice inoculated only with fungal cells. This effect was not observed when the mice were infected only 1 week after tumor transplantation. A significant decrease in the number of C. albicans cells in the kidneys was observed in mice inoculated with fungal cells 2-3 weeks after tumor transplantation. In the tumor-bearing mice treated with cyclophosphamide (CY), a remarkable decrease in both the number of peripheral blood polymorphonuclear leukocytes (PMNs) and the defense against challenge with C. albicans cells was observed, as compared with the CY-untreated groups (normal and tumor-bearing mice). A marked increase in the calcium concentration in serum and number, candidacidal activity, active oxygen level, and myeloperoxidase activity of PMNs was observed in the 2-3-week tumor-bearing mice. From these results, it is suggested that PMNs, which accumulated in the 2-3-week tumor-bearing mice, play an important role in the protection from C. albicans infection by increasing the number and the types of killing factors.

Abstract
OBJECTIVE To study the anti-tumor effect and immune function modulation of Xiaoliu decoction (XLD) and to explore the possible mechanism. METHODS S180 tumor bearing mice were treated with large or small dose of XLD and cyclophosphamide (CTX) to observe the tumor suppressive rate, lymphocyte transformation rate, natural killer cell (NK) activity, tumor necrosis factor alpha (TNFalpha) level in the mice, as well as the tumor cell apoptosis in vitro. RESULTS The tumor suppressive rate of XLD on tumor bearing mice was over 30%. XLD showed obvious trend in enhancing the tumor suppressing rate of chemotherapy, could increase the lymphocyte transformation rate, NK activity, and TNFalpha level. It also could accelerate the tumor cell apoptosis in vitro. CONCLUSION XLD has significant anti-tumor effect, it could elevate the immune function or organism and alleviate the chemotherapy induced lowering of immune function.

Abstract
OBJECTIVE To observe the effect of the antibody to a B cell epitope on mouse Toll-like receptor-2 (mTLR-2) extracellular domain on the growth of murine fibrosarcoma. METHODS An immunogen was prepared by conjugating a 20-mer peptide, synthesized on the basis of prediction for B cell dominant epitope of mTLR-2, to a carrier protein. Rabbit polyclonal antibodies against B cell epitope of mTLR-2 were prepared and purified, and characterized by Western blotting, immunohistochemistry and flow cytometry. Murine fibrosarcoma S180 cells were inoculated into the left hindlimbs of Swiss mice, and in the treatment group, the injected cells were mixed with 100 microg anti-mTLR-2 antibody TSP-1, with the same dose of irrelevant rabbit IgG in the IgG control group and with buffer solution only in the blank control group. The mice in each group were anesthetized and sacrificed on days 10, 14, and 18 following the injections, respectively, and the weight of the tumors was measured and the inhibition rate calculated. RESULTS A distinct band for the antibody TSP-1 was shown at the relative molecular mass of 95 000 by Western blotting. The antibody TSP-1 could also react with native mTLR-2 expressed on J774A.1 cells, as identified by immunohistochemistry and flow cytometry. The growth of the fibrosarcoma S180 was obviously inhibited by injections with the antibody TSP-1 mixture, and the weight of tumor in mice treated with TSP-1 was significantly lower than that in the two control groups (P<0.05), with an inhibition rate of 77% on day 10, 51% on day 14 and 53% on day 18. CONCLUSION Local application of the antibody against B cell epitope on mTLR-2 extracellular domain can inhibit the growth of murine fibrosarcoma, especially in the early stage of tumor proliferation.

Abstract
OBJECTIVE To discuss the effect of the association of Shiquandabutang with Hetaokun on the protection to liver and immunity of tumor mouse S180. METHOD Through the comparison between tumor transplanted and tumor cultured completely out of cell body, the effect was investigated, with Hetaokun singly used and Shiquandabutang associated with Hetaokun, on the level of SGPT, licking up function of monocyte macrophage, thymus index, spleen index and transform percentage of lymphocyte of the mouse S180. The scanning electron micrographs indicated the protective function of the association of Shiquandabutang with Hetaokun for liver. RESULT 12.5 mg x kg(-1) Hetaokun could obviously restrain the tumor when it was singly used at 73.1%, but it increased SGPT at the same time. The association of Shiquandabutang with Hetaokun could protect liver of the mouse S180. SGPT (P > 0.05) was compared with the common ones and the result showed that the association of shiquandabutang with Hetaokun could make K value increase (P > 0.01). Through the scanning electron micrographs, association of two medicines was found to change liver cells little and expansion of rough Neizhiwang was not found. Compared with the control group, the immunity of the two tumor mouse groups taking the medicine mentioned above was promoted obviously. CONCLUSION The association of Shiquandabutang with Hetaokun can enhance the efficiency and decrease poison of them to body. With the promotion of immunity of the body, the efficiency is enhanced on the whole.

Abstract
Various low-molecular-weight chitosans such as the 21-kDa, 46-kDa, and 120-kDa chitosans obtained by enzymatic hydrolysis of a high-molecular-weight chitosan (average molecular weight, 650 kDa) had low viscosity and were water soluble. We examined the antitumor activity of various water-soluble chitosans with different molecular weights in sarcoma 180-bearing mice. A 21-kDa water-soluble chitosan and oligochitosan (100 and 300 mg/kg body) administered by i.g. intubation reduced the tumor growth and final tumor weight in sarcoma 180-bearing mice. A 46-kDa water-soluble chitosan at a dose of 100 mg/kg body reduced the tumor growth and final tumor weight, but had no effect at 300 mg/kg. On the other hand, a 130-kDa water-soluble chitosan had no effect on tumor growth. The 21- and 46-kDa chitosans (10 mg/L) enhanced the natural killer (NK) activity in intestinal intraepithelial lymphocytes (IELs) or splenic lymphocytes. The NK activity of low-molecular-weight chitosan (21- and 46-kDa chitosans)-treated IELs or splenic lymphocytes was stronger than that of high-molecular-weight chitosan (130- and 650-kDa chitosans)-treated IELs or splenic lymphocytes. In addition, low-molecular-weight chitosan-treated IELs or splenic lymphocytes also enhanced the cytotoxic activity against sarcoma 180 cells. In an in vivo study, although low-molecular-weight chitosan-treated IELs had cytotoxic activity against tumor cells, splenic lymphocytes treated with chitosans had no effect. These findings suggest that the antitumor activity of low-molecular-weight chitosans (12- and 46-kDa chitosans) and oligochitosan might be due in part to the enhancement of NK activity in IELs. Thus, the low-molecular-weight chitosans or oligochitosan might be useful in preventing tumor growth through the activation of intestinal immune functions.

Abstract
Agaricus blazei (H1 strain) was tested for its anticancer activity using a sarcoma 180 (S180) inoculation model and the changing patterns of splenocyte subsets were examined. Its hot-water extract was administered orally to ICR and KSN nude mice that were inoculated with S180. The growth of S180 was significantly inhibited in A.blazei treated groups. Pan T cells significantly increased in all treated groups compared to controls, even in KSN nude mice. Splenocyte subset changes were slightly different between ICR and KSN nude mice. This S180 inoculation model proved to be effective in screening the antitumor effect of basidiomycetes and allowed comparisons of immunological cellular changes between the mouse strains.

Abstract
Most of the synthetic chemotherapeutic agents available today are immunosuppressants, cytotoxic, and exert variety of side effects that are particularly evident in cancer chemotherapy. Botanical based immunomodulators are often employed as supportive or adjuvant therapy to overcome the undesired effects of cytotoxic chemotherapeutic agents and to restore normal health. Total extract, polar and non-polar extracts, and their formulations, prepared from medicinal plants mentioned in Ayurveda, namely, Withania somnifera (Linn Dunal) (Solanaceae), Tinospora cordifolia (Miers) (Menispermaceae), and Asparagus racemosus (Willd.) (Liliaceae), exhibited various immunopharmacological activities in cyclophosphamide (CP)-treated mouse ascitic sarcoma. Treatment of ascitic sarcoma-bearing mice with a formulation of total extracts of Withania somnifera and Tinospora cordifolia (80:20) and alkaloid-free polar fraction of Withania somnifera resulted in protection towards CP-induced myelo- and immunoprotection as evident by significant increase in white cell counts and hemagglutinating and hemolytic antibody titers. Treatment with these candidate drugs will be important in development of supportive treatment with cancer chemotherapy.

Abstract
AIM To observe the influence of bondage stress on Th1/Th2 cytokines and growth of tumor in mice bearing S180 tumor cells. METHODS 2 x 10(6) S180 tumor cells were injected subcutaneously into the murine right oxter,and bondage stress was imposed on mice for 8 hours per day,ten days running. Then T lymphocyte proliferation was detected by MTT colorimetry. IFN-gamma and IL-2 secreted by splenocytes was measured by mitogen-activating lymphoblast assay and macrophage NO production assay. At the same time, the levels of IL-4 and IL-10 in serum were detected by ELISA, and the weight of the tumors and thymuses were measured. RESULTS Compared with mice only injected with S180 tumor cells, tumor bearing mice suffered from bondage stress showed decreased T lymphocyte proliferation, thymus index, and levels of IFN-gamma and IL-2, but increased levels of IL-4 and IL-10(P<0.05), and tumor weight (P<0.01). CONCLUSION Bondage stress could aggravate the suppression of cellular immunity in mice bearing S180 tumor and promote the T cells to shift towards Th2 type cells, which may be one of the mechanisms of promoting tumor growth by bondage stress.

Abstract
AIM To explore the role of nitric oxide (NO) in cytotoxicity of macrophages. METHODS 20 mice of Kunming species were divided into two groups. One group were injected subcutaneously with rhabdosarcoma cells S180 and the other were normal controls. The macrophages in peritoneal lavage fluid of two groups of mice were co-cultured with tumor cells K562. L-arginine(L-Arg) or NG nitro L-arginine methyleste(L-NAME) was added to the culture medium, and the cytotoxicity of macrophages was measured. RESULTS Macrophages from tumor bearing mice had stronger cytotoxicity than those from normal mice. L-Arg increased and L-NAME decreased the cytotoxicity of macrophages from tumor bearing mice, but both had no effect on the cytotoxicity of macrophages from normal mice. CONCLUSION NO is an effector molecule in cytotoxicity of activated macrophages.

Abstract
OBJECTIVE To study the antitumor activity and mechanism of aloe polysaccharides (AP). METHODS AP was administered i.p. or i.v. to Sarcoma 180(S180) bearing mice or Hepatoma22(H22) bearing mice solely or combining with CTX, FU and ADM respectively. 10 days later, for S180 mice, the blood was analyzed, the tumor was peeled off and weighed, and the spleen index, thymus index was calculated. For H22 bearing mice, the survival rate was observed or the IL-2, TNF content in serum was tested. RESULTS 25 mg/kg.d or 50 mg/kg.d AP group could evidently reduce the tumor weight of S180 bearing mice and prolong the survival time of H22 bearing mice. AP also could improve the antitumor effects of CTX, ADM, FU, and lessen the chemotherapy side-effects. Furthermore, AP could improve the level of IL-2, TNF in the serum of mice bearing S180 or H22. CONCLUSION AP has the effects of antitumor, enhancing the antitumor activity of chemotherapy drugs and lessening their side-effects. This effect was possibly derived from inducing IL-2 and TNF producing in body and improving the immunity activity.

Abstract
In the sarcoma S180 ascitic mice, the effects of moxa-cone moxibustion at Guanyuan (CV 4) on erythrocytic immunity and its regulative function were investigated. The results indicated that moxibustion at Guanyuan (CV 4) could significantly increase the decreased erythrocytic C3b receptor rosette forming rate (RBC-C3bRR), lower the raised erythrocytic immunocomplex rosette forming rate (RBC-ICR, P < 0.05 or P < 0.01), increase the decreased activity of erythrocytic immuno-accelerative factor, and reduce the increased activity of erythrocytic immunosuppressive factor (P < 0.05) in the tumor-bearing mice. This suggests that moxibustion at Guanyuan (CV 4) can strengthen erythrocytic immunity and promote its regulative function.

Abstract
Fungus polysaccharides compounds (FPC) are the mixture of procyanidins oligomers, glycyrrhetinicacid and polysaccharides of hericium erinaceus, lentinus edodes and poria cocos. The antitumor effects of FPC and its immunity regulating effects as an immunostimulant on the mice burdened with sarcoma 180 (S-180) were studied. FPC (100, 200 and 400 mg/kg BW) was gavaged to mice for 31 days. S-180 was transplanted to these mice on the 21th day. Lentinus edodes group was gavaged 200 mg/kg BW saccharine of lentinus edodes. The results showed that FPC could inhibit the growth of S-180 effectively. The inhibitory rates were 37.74%, 44.73% and 48.32% respectively. The antineoplastic activity of FPC (200 mg/kg. BW) was more effective than polysaccharide of lentinus edodes at the same dose. In S-180 burdened mice, the percentage of L3T4 and the ratio of L3T4/Lyt-2, NK activity and the induced IL-2, IFN-gamma levels were decreased significantly compared with the normal control group. As an immunostimulant, FPC could increase the percentage of L3T4 and the ratio of L3T4/Lyt-2 in S-180 burdened mice, but had no significant effects on the percentage of Lyt-2. Polysaccharide of lentinus edodes alone could also increase the immunity competence of mice burdened with S-180, but was not better than that of FPC at the same dose. It could be concluded that the compound of antineoplastic component could be synergetic.

Test items included sarcoma 180(S180) inhibiting test, Ehrlich ascites carcinoma (EAC) inhibiting test, phagocyte phagocytosis test and NK cell activity test. The results showed dose-response tendencies in all indices. But the tumor inhibition rate and survival time were decreased in high dose groups and even lower than those of control group (P < 0.05) in some samples. Correlation analysis showed a positive correlation between tumor inhibition rate and survival time, phagocytic percentage and phagocytic index, phagocytic percentage and NK activity, phagocytic index and NK activity (P < 0.01). Tumor inhibition rate and phagocytic percentage appeared negative correlation (P < 0.05). It is suggested that the present methods should be modified. The new and better methods needed to be established. The judge criterion for functional food should be strictly enacted. More Studies needed to be repeated for some foods with significant tumor inhibition functions.

Abstract
We report that tumor necrosis factor (TNF) alpha induced a strong antitumor immune reaction when it was produced in arteries leading to tumors by gene transfer in vivo. We used a mouse model carrying a sarcoma-180 tumor in the right footpad and injected the fusogenic liposomes encapsulating the human TNF-alpha gene into the right femoral artery. Under this condition, human TNF-alpha was detected only in the artery leading to the tumor and in the tumor. There was a significant regression in tumor growth when the TNF-alpha gene was delivered into the right femoral artery, with 4 of 11 mice completely cured. No regression was observed when the TNF-alpha gene was delivered into the left femoral artery or into the tumor or when the luciferase gene was administered. Tumor regression was inhibited by the injection of anti-TNF-alpha, anti-CD4, or anti-CD8 monoclonal antibody, and CD8+ T cells accumulated in the tumors of TNF-alpha-treated mice. These results suggest that TNF-alpha expressed locally in the arteries leading to tumors efficiently suppresses tumor growth through reinforcement of an antitumor immune reaction. The significance of this phenomenon for cancer gene therapy was discussed.

Abstract
Pingxiaozhitong pill was administered ig. once daily for 7 successive days at dosages (4,2,2 g/kg). It was shown markelly suppressive effects on solid sarcoma 180 (S180) and Ehrlich aseites carcinoma (EAC) and synergism effect on cytoxan inhibiting S180 in mice. It had significant analgesic effect. 4,2 g/kg pingxiaozhitong pill enhanced effects on phagocysis of monocyte macrophage and value of hemagglutinin in serum in mice.

Abstract
OBJECTIVE To investigate the tumor-suppressive activity of polyactin B (PB) and the life-span of tumor bearing mice treated with PB and the anti-tumor mechanisms of PB by blockage of macrophage in vivo. METHODS Thirty-two S180 sarcoma-bearing (s.c.) BALB/c inbred mice were divided into 4 groups, i.e., control group (8 mice), PB group (8), Trypan blue (TrB) group (8) and PB + TrB group (8). Five days after PB injection (i.p.), the tumor size of the mice was measured, and the ratio of TNA to TTA in HE section of the tumor maximal area was calculated and the pathological features of the tumors were observed. Forty S180 sarcoma-bearing (i.p.) ICR mice, which were randomly divided into 4 groups as above, were used for observation of the life-span. RESULTS PB could strongly inhibit the growth of S180 sarcoma with the tumors regressing completely in 3 of 8 mice, prolong the life-span of mice bearing S180 sarcoma, increase the infiltration of macrophages and lymphocytes in the periphery and inside of the tumors. In addition, there were more prominent hemorrhagic necrosis, neutrophil infiltration and microthrombi in small vessels around the necrotic areas in the tumors of PB treated group. The tumor-suppressive effect of PB disappeared after macrophage system blockage with TrB. In PB + TrB, TrB, control and PB groups, the size of tumors reduced, and the life-span of mice increased in successive order. CONCLUSIONS (1) PB is a strong activator of macrophage. (2) In vivo the tumor-suppressive effect of PB is initially mediated by PB activated macrophage system. Then other immunocompetent cells, e.g., T-cells, NK-cells, etc, activated directly and/or indirectly by PB, may play a very important role in tumor suppression. (3) PB-activated macrophages are more sensitive to TrB blockage. Therefore, using TrB + PB to block macrophage system is more effective than TrB alone. (4) Blockage of macrophage function might influence the life-span of the mice.

Abstract
The effects of Jianpizengmian (JPZM) granule on tumor growth and immune function were researched in tumor-bearing mice. The results showed it had significant inhibiting activity against S180 and HePA by oral JPZM. The inhibitory rate of JPZM reached 46.25% and 45.57%. JPZM could markedly increase the index of spleen and thymus, the level of serum hemolysin and the spleen lymphocytes transformation in tumor-bearing mice, compared to control group (H2O) respectively.
