Introduction and Aim: Constant efforts are exerted to explore unique bioactive principles from natural sources that possess more effective specific antineoplastic activities. In the present study, we aimed evaluate antitumor activity of stem bark extract Oroxylum indicum in mice bearing Ehrlich ascites carcinoma (EAC). Materials Methods: Ninety female Swiss albino were categorized into fifteen ...

A large number of plants belonging to the Hypericum family are known to possess strong antitumor properties. The methanol extract of H. hookerianum Wight and Arnott stem (MEHH) exhibited potent in vitro cytotoxic activity against various cancerous cell lines. In the present study, the high performance liquid chromatography (HPLC) standardized MEHH was tested for in vivo antitumor properties aga...

The aim of the present work was to synthesise coumarinyl heterocycles and to elucidate the potential role of these compounds as antioxidants and cytotoxic agents against Dalton's lymphoma ascites tumour cells (DLA) and Ehrlich ascites carcinoma cells (EAC). The synthesis of coumarin derivatives containing pyrazole, pyrazolone, thiazolidin-4-one, 5-carboxymethyl-4-thiazolidinone and 3-acetyl-1,3...

The binding proteins for Sarcophaga lectin and wheat germ agglutinin on the surface of Ehrlich ascites tumor cells were compared. Studies with antibody against the binding protein for Sarcophaga lectin showed that these two binding proteins are different. Since these two lectins are both active in the lectin-dependent macrophage-mediated cytotoxic reaction with Ehrlich ascites tumor cells as ta...

Infection of the Ehrlich ascites tumor with Bunyamwera virus inhibits mitosis and induces changes in the nucleus and cytoplasm of the intermitotic cell; margination of the nuclear chromatin is accompanied by the development of prominent parachromatin bodies and multiple nuclear bud ding which leads to complete nuclear destruction (12). Throughout this process there is an increase in the cytopla...

It has previously been shown that the incorporation qf both C14-formate into DNA1 thymine and P32-orthophosphate into DNA phosphate of the hypotetraploid strain of Ehrlich ascites tumor cells in vitro is strongly inhibited by deoxyadenosine.2 It was, furthermore, shown that this inhibition is not due to a prevention of the de novo synthesis of acid-soluble thymine compounds. The incorporation o...

Cancer is a malignant disease that is characterized by rapid and uncontrolled formation of abnormal cells which may mass together to form a growth or tumor, or proliferate throughout the body. Next to heart disease, cancer is a major killer of mankind. This study aims at a preliminary phytochemical screening and anticancer evaluation of Adiantum venustum Don against Ehrlich Ascites Carcinoma in...

RNA polymerases I and II were partially purified from L1210 ascites cells by sonic disruption, batchwise treatment with diethylaminoethyl (DEAE) cellulose, ammonium sulfate-fractionation, and subsequent linear KCl gradient chromatograpy on DEAE cellulose column. The RNA polymerases from L1210 cells showed similar enzymatic properties as in cases of Ehrlich carcinoma-RNA polymerases. RNA polymer...

An extract of Ruta graveolens was found to be cytotoxic to Dalton's lymphoma ascites (DLA), Ehrlich ascites carcinoma (EAC) and L929 cells in culture (IC100=16 mg/ml) and also to increase the lifespan of tumour bearing animals. The extract further decreased solid tumours developing from DLA and EAC cells when given simultaneously with elongation of the lifespan of tumour-bearing animals. A home...

1. Ehrlich ascites-cell extracts convert choline and ethanolamine approximately equally well into their respective phosphoryl derivatives. 2. Choline is a potent inhibitor of ethanolamine phosphorylation, but ethanolamine has little effect on choline phosphorylation. 3. 2,3-Dimercaptopropanol, cysteine and Ca2+ inhibit ethanolamine phosphorylation, but have no detectable effect on choline phosp...
