摘要:
This invention relates to a method for preparing a proliferation inhibitor for malignant tumour cells of animals including human beings, and the method comprises the steps of cultivating the malignant tumour cells of the animals, afterward transferring them to a culture medium for extraction, adding glucose to the medium, carrying out a cultivation therein, afterward removing the malignant tumour cells therefrom, and collecting the remaining culture medium.
摘要:
Agents for inhibiting the proliferation of malignant tumour cells are described together with processes for their preparation. Malignant tumour cells are cultivated in a culture medium for a period before being removed therefrom. By means of fractional filtration from the culture medium, that fraction having a molecular weight of not less than 500 is separated. Results show that this fraction has a significant inhibiting effect against proliferation of malignant tumour cells.

An agent for inhibiting proliferation of human malignant tumor cells is obtained by culturing the human malignant tumor cells in a medium and removing the malignant tumor cells from the cultured medium.
摘要:
An inhibiting agent against the proliferation of malignant tumour cells is produced by first incubating malignanttumour cells, and then further incubating the malignant tumour cells after adding serum protein or albumin to the culture medium. The medium is isolated by removing the cells, and is then subjected to ultra-fiftration through a filter for the molecular weight of 10,000. The fraction having a molecular weight of 10,000 or more is separated.
摘要:
An inhibiting agent against the proliferation of malignant tumour cells is produced by incubating malignant tumour cells in a culture medium and removing the cells therefrom. The residual culture medium is extracted with n-butanol as solvent. The solid matter is isolated by evaporation to dryness.
