Nitrogen mustard and triethylene melamine content in normal and tumor tissues after intra-arterial and intravenous injection in rats.

چکیده
In recent years a number of reports have indi cated that nitrogen mustard exerts a greater effect in certain human neoplasms when admin istered intra-arterially than when given by the conventional route of injection (1, 2, 3, 11-13). Intra-arterial treatment was originally considered of value primarily in neoplasms confined to the extremities or head. Maxfield and his associates have recently treated more generalized carcinomatosis of the abdominal and thoracic cavities by regional injections of nitrogen mustard and have obtained beneficial results. There appear to be at least three possible explanations for the increased effectiveness of nitrogen mustard when it is injected intra-ar terially rather than intravenously. There may be: (a) an increased selective uptake of the agent by the tumor, (o) a simple increase in concentration of the agent in all the tissues, including the tumor in the region supplied by the injected artery; and (c) an increased tolerance to the drug by the patient which allows the use of larger amounts of nitrogen mustard than may be employed when intravenous administration is used. The present study was undertaken to determine which, if any, of the above hypotheses could serve to explain the enhanced action of nitrogen mustard when injected intra-arterially, and coupled with this were studies to determine if there were simi lar increases in the effect of triethylene melamine administered under similar conditions. The degree of localization of these two drugs in various tis sues, including neoplasms, was also investigated.

X-radiation remains the treatment of choice in most cases of leukemia and lymphoma, but new agents are playing an increasing role in therapy. Radioactive phosphorus does not produce radiation sickness and results with it are comparable to those of x-ray therapy in chronic leukemia. Urethane and nitrogen mustard may produce remissions in patients with chronic leukemia who have become resistant t...

Effect of cell division inhibition on the phosphorus metabolism of growing cultures of Saccharomyces cerevisiae.
Radiation and certain organic chemicals, under appropriate experimental conditions, may selectively inhibit cell division but not growth of cultures of Saccharomyces cerevisiae which are in the logarithmic stages of both growth and division (Lea et al., 1937; Spoerl et al., 1954; Loveless et al., 1954). The inhibition of cell division (multiplication) without a concommitant inhibition of growth...
