Anti-tumor activity of Euphorbia hirta (50 mg/kg and 100 mg/kg) has been evaluated against Ehrlich's ascites carcinoma (EAC) in Swiss albino mice. Intraperitoneal (i.p) administration of Euphorbia hirta was effective in reducing solid tumor mass development induced by EAC cells. It exhibited significant anti-tumor activity in mice, when used at the dose of 100 mg/kg/day i.p., for 14days. The administration of Euphorbia hirta (100 mg/kg/day i.p.) resulted in an increase (P<0.001) of the life span (59.9%) of ascites tumor bearing mice as compared to the control group. After 14 days, on developed tumor masses, Euphorbia hirta administration brought about significant reduction in tumor volume and it reverse the changes in the hematological parameters, responding to tumor inoculation. The results are indicative of the anti-tumor activity of Euphorbia hirta against EAC induced tumor in a dose dependent manner.

In the present study, the ethanolic leaf and bark extract of Wrightia tomentosa were tested for comparative in vivo antitumour properties against Ehrlich ascites carcinoma (EAC) tumour bearing mice at 100 and 200 mg/kg body weight doses given orally once daily for 16 days. The EAC mice receiving 100 and 200 mg/kg ethanolic leaf and bark extract showed a dose dependent elevation in tumour, free survival and a highest number of survivors were observed at 200 mg/ kg for leaf extract of ethanol, which was considered as an optimum dose for its anti neoplastic action. The Median survival time for this dose was approximately 44 days when compared with 23 days of non-drug treated controls. The results indicate that the administration of leaf extract not only increased the survival of animals with ascites tumour and reduced packed cell volume and viable tissue cell count, but also altered many hematological parameters changed during tumour progression, indicating the potent antitumour nature of leaf extract than the bark extract. Statistical analysis also reveals that the leaf extract showed highly significant anti tumour potency (p < 0.001) when compared with control.

The present study was designed to determine the antitumor and antioxidant properties of methanol extract from the root of Galega purpurea (Papilionaceae) (MEGP) against Ehrlich Ascites Carcinoma (EAC) bearing Swiss albino mice. Acute and short-term toxicity studies were performed initially in order to ascertain the safety of MEGP. The effect of MEGP on the growth of transplantable murine tumor, life span of EAC bearing hosts and simultaneous alterations in the hematological profile and liver biochemical parameters (lipid peroxidation, antioxidant enzymes) were estimated. The MEGP showed decrease in tumor volume, packed cell volume and viable cell count and increases the nonviable cell count and mean survival time thereby increasing life span of EAC tumor bearing mice. Hematological profile reverted to more or less normal levels in extract treated mice. Treatment with MEGP decreased the levels of lipid peroxidation and increased the levels of glutathione, superoxide dismutase and catalase. The results suggested that the methanol extract of Galega purpurea root exhibited antitumor effect by modulating lipid peroxidation and augmenting antioxidant defense system in EAC bearing mice.

The plant Ichnocarpus frutescens (Linn) R.Br. (Family-Apocynaceae) has been indicated for the treatment of various diseases, one amongst it is cancer. The purpose of this study was to investigate experimentally the possible antitumor activity and antioxidant role of Ichnocarpus frutescens in the mice transplanted with Ehrlich ascites carcinoma (EAC). The chloroform and methanol extract of whole plant of Ichnocarpus frutescens (CEIF and MEIF) were administered intraperitoneally at the dose of 150 mg/kg and 300 mg/kg, body weight per day for 7 days after 24 h of tumor inoculation in mice. Treatment with CEIF at the dose of 150 mg/kg and 300 mg/kg remarkably decreased the tumor volume, packed cell volume, viable cell count and increased the nonviable cell count of EAC tumor bearing mice when compared to e effect of MEIF at 150 mg/kg and 300 mg/kg. Further the EAC mice treated with CEIF and MEIF showed significant decrease in the level of lipid peroxidation and significant increase in the level of antioxidant enzymes such as glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT), however the decreasing and increasing capacity of CEIF was less in both doses as compared to MEIF. Based on these results, it can be concluded that the chloroform and methanol extact of Ichnocarpus frutescens exhibit significant antitumor and antioxidant activity in EAC bearing mice.

The antitumor activity of crude saponin mixture obtained from Luffa tuberosa (Roxb.) (Fam; Cucurbitaceae) hairy roots (CSLT) in mice transplanted with Ehrlich ascites carcinoma (EAC) was investigated. The EAC-bearing mice receiving 150 and $300{\mu}g/kg$ body weight, (i.p) of CSLT have shown a dose dependent elevation in tumor-tree survival and a highest number of survivors were observed after administration of CSLT $(300{\mu}g/kg)$, which was considered as an optimum dose for its antineoplastic action. The mean survival time (MST) for this dose was approximately $47.1{\pm}0.74d$, when compared with $19.0{\pm}0.36d$ of untreated control. Administration of $300{\mu}g/kg$ CSLT resulted in 130% long-term increased survival time. The measurement of body weight, tumor volume, packed cell volume, viable and non-viable count indicated the efficacy of CSLT in tumor-bearing mice, there was a significant recovery in hematological profiles, and there was depletion in lipid peroxidation levels, and the antioxidant enzyme activities such as GSH, SOD and CAT were restored to near the normal levels. The CSLT was found to be devoid of conspicuous short-term toxicity in the mice when animals were intraperitoneally injected with 250, 500, 750 and $1000{\mu}g/kg$ bodyweight. The treated mice showed conspicuous toxic symptoms only at a dose of $1500{\mu}g/kg$. Mortality of the animals was monitored up to 14 d post drug treatment, $1/7^{th}$ of the $LD_{50}$ dose has been considered for the optimal antineoplastic activity.

In order to investingate the effects of Jukyeopseokgotanggagambang Extract on antitumor effects after human cell lines(A549, hep3B, Caki-1, Ehrlich) transplantation into the peritoneal cavity or right groin in mice induced by RPMI 1640 and GIBCO etc., the extracts of its herbal medicines were orally administered for 10 or 12days. Experimental studies were performed for measurance of antitumor effect of MMC(Mitomycin C) and lysosomal enzyme's activities using colony forming efficiency, SRB assay which were regarded as a valuable method for antitumor effects of unknown compound on tumor cell lines. The results obtained in this studies were as follows: 1. According to the change of colony-forming efficiency and SRB assay of Caki-1 cell, hep3B and A549 cells after exposure to the extract of Jukyeopseokgotanggagambang extract, that extract depressed the growth of tumor cells depending on its concentration. 2. Antitumor activities of the ethanol extract from Jukyeopseokgotanggagambang extract and MMC on ascites form of Ehrlich carcinoma in mice is a little improved. Especially mean survival times of the group of Jukyeopseokgotanggagambang extract 200mg/kg and MMC 0.1mg/kg is improved over 30%. 3. When Jukyeopseokgotanggagambang extract and MMC are administerated together, the weight of tumor is more decreased than MMC alone. 4. The effects of the Jukyeopseokgotanggagambang extract and MMC on the lysosomal enzymes in Ehrlich ascites carcinoma cell are more significantly improved than MMC alone. 5. Jukyeopseokgotanggagambang extract also increased the uptake of MMC into Ehrlich carcinoma cells. According to the above results, it could be suggested that Jukyeopseokgotanggagambang extract has indirect autitumor effects by strengthening the effects of MMC on tumor cells.
