Gemcitabine is an anti-cancer drug with clinically uses in the treatment of various neoplasms, including breast, ovarian, non-small cell lung, pancreaticand cervical cancers, T-cell malignancies, germ cell tumours, and hepatocellular carcinomas. However, it has also been reported to have many adverse effects. Naturally occurring anti-mutagenic effects, especially those of plant origin, have recently become a subject of intensive research. The present study was therefore designed to investigate the anti-mutagenic effects of Salvia merjamie (Family: Lamiaceae) plant extracts against the mutagenic effects of gemcitabine. The anti-mutagenic properties of Salvia merjamie were tested in Inbred SWR/J male and female mice bone marrow cells. The mice were treated in four groups; a control group treated with 30 mg/kg body weight gemcitabine and three treatment groups, each with 30 mg/kg body weight gemcitabine together with, respectively, 50, 100 and 150 mg/kg body weight Salvia merjamie extract. Chromosomal aberration and mitotic index assays were performed with the results demonstrating that Salvia merjamie extract protects bone marrow cells in mice against gemcitabine induced mutagenicity. This information can be used for the development of a potential therapeutic anti-mutagenic agents.

Chenopodium album Linne (CAL) is a fast-growing weedy annual plant. The leaves and young shoots may be eaten as a leafy vegetable. In oriental medicine, CAL has been used for treatment of skin disease, fever, stomach ache, toothache, and paralysis. After a preliminary screening of CAL ethanol extract and its fractions obtained from CAL leaves for anti-gastritic and anti-Helicobacter pylori (H. pylori) activity, the butanol (BuOH) fraction was found to have the most significant effect. We also examined antioxidative properties of the total CAL extract and its fractions, and also betaine as an ingredient of the BuOH fraction. To investigate the antioxidant effects of CAL on gastritis, the reducing power, free radical scavenging activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH), and lipid peroxidation effects were determined. Additionally, the BuOH fraction reduced cell viability in a concentration dependent manner in human gastric cancer cell lines. The results of this study revealed that CAL has excellent antioxidant activity, and may be useful in treating gastritis and gastric cancer.

At once Medicine of East and West have the same purpose in treating, but there is a difference between the method of medical care and the view/slant on a disease each other. In the East Medicine, It is very difficult to explain the concept of Hwalhyulhwau but it is one of the way to cure cancer for long time. Be based on the theory of the East Medicine, research single medicine's anti-cancer effect among the natural products that has anti-cancer function. Moreover, for the purpose of finding new way to cure and prevent against cancer, we, the researchers, divided into four groups for this research: Group one: survey new substance with anti-cancer effects from natural products. Group two: research of anti-cancer mechanism through the experimental studies. Group three: research of immune responses in anti-canncer effects from natural products. Group four: research of the inhibitory effect on metastasis through the anti-angiogenesis. From the above results, we blended efficacious medidcines against cancer and made new prescriptions of Soam-I and Soam-II. Now, we are studying on these new prescriptions. We speculate that Soam-I and Soam-II may be used for a new conceptional anticancer therapy.

Although marine living organism contains a numerious number of compounds, it is difficult to collect these compounds in a large scale for medicinal application. However, in recent years, several bioactive compounds isolated from marine macroalgae have been proved to be able to provide potential sources for development of medicinal products because they can be obtained in large amount from marine. A number of studies have reported a variety of effects of marine macroalgae but a few anti-inflammatory activity of marine macroalgae have recently been published. Herein, we reviewed novel anti-inflammatory compounds recently isolated from marine brown algae, green algae and red algae. From this survey, in particular, some compounds contained in edible macroalgae exert anti-inflammatory effects with inhibition on cyclooxygenase-2 (COX-2), inducible nitric oxide synthase(iNOS) and matrix metalloproteinases (MMPs) activity regulated by nuclear factor-kappa B transcription factor that play a key role in cancer as well as inflammation, demonstrating to be able to potentially apply to development of anti-inflammatory agent for chemoprevention of cancer. Furthermore, some macroalgae and their compounds with both excellent anti-inflammatory activity and very low toxicity can select a potential candidates capable of preventing or treating several chronic inflammation such as colitis, hepatitis and gastritis, leading to cancer.

Cancer is a leading cause of death worldwide. Due to the toxic side effects of the commonly used chemotherapeutic drug cyclophosphamide (CTX), the use of herbal medicines with fewer side effects but having potential use as inducing anti-cancer outcomes in situ has become increasingly popular. The present study sought to investigate the effects of a methanolic extract of Bauhinia tomentosa against Dalton's ascites lymphoma (DAL) induced ascites as well as solid tumors in BALB/c mice. Specifically, B. tomentosa extract was administered intraperitonealy (IP) at 10 mg/kg. BW body weight starting just after tumor cell implantation and thereafter for 10 consecutive days. In the ascites tumor model hosts, administration of extract resulted in a 52% increase in the life span. In solid tumor models, co-administration of extract and CTX significantly reduced tumor volume (relative to in untreated hosts) by 73% compared to just by 52% when the extract alone was provided. Co-administration of the extract also mitigated CTX-induced toxicity, including decreases in WBC count, and in bone marrow cellularity and ${\alpha}$-esterase activity. Extract treatment also attenuated any increases in serum levels of $TNF{\alpha}$, iNOS, IL-$1{\beta}$, IL-6, GM-CSF, and VEGF seen in tumor-bearing hosts. This study confirmed that, the potent antitumor activity of B.tomentosa extract may be associated with immune modulatory effects by regulating anti-oxidants and cytokine levels.

Objectives: The aim of the experiment is to identify any anti-tumor effects of Duchesnea indica(Andr.) Focke on stomach, liver, urinary bladder, prostate and kidney cancer cells. Materials & Methods: For cancer cells, AGS stomach, Hep3B and Hep3G2 liver, HT-1197, HT-1376 urinary bladder, PC3 prostate, and A-704 kidney cancer cells, all obtained from Korean Ce 11 Line Bank, were used. The boiled extract of Duchesnea indica(Andr.) Focke (10 and 20 microliters) was injected into cultures, and the cultures were observed at 0, 6 and 12 hours, and from then on at 12 hours intervals up to 72 hours. The destruction of stomach, liver, urinary bladder, prostate and kidney cancer cells were measured through Trypan blue exclusion testing. The suppresion on viability of stomach, liver, urinary bladder, prostate and kidney cancer cells was measured via MTT assay. Anti-cancer mechanisms were assessed by analyzing the cell cycle. Results: In morphologic change, AGS, Hep3B, HepG2 showed the withdrawn and floating appearance that is typical in cellular impairment. The destruction of AGS, HT-1197, HT-1376, A-704, PC-3, Hep3B and HepG2 cancer cells in each test group was greater than that in the control group to a statistically significant degree. The suppression on viability of AGS, HT-1197 and Hep3G in each test group was greater than that in the control group to a statistically significant degree. Analysis of the cell cycle after injection of D... Focke showed inhibition of cell division in all test groups(AGS, Hep3B, HepG2, HT-1197, HT-1376, PC3, A-704). Conclusions: The results of this experiment suggest that Duchesnea indica(Andr.) Focke has statistically significant anti-tumor effects on stomach, urinary bladder, kidney, prostate and liver cancer, of which stomach and liver cancer are prominently significant. This in vitro experiment supports a role for Duchesnea indica(Andr.) Focke as a potential cancer treatment, but progressive research on Duchesnea indica(Andr.) Focke and its anti-tumor effects is needed to develop a practical application for it in cancer treatment.
