title: [EVALUATION OF THE CYTOGENETIC AND MUTAGEN-MODIFYING ACTIVITY OF CAFFEINE IN MOUSE BONE MARROW CELLS].
abstract: The cytogenetic and mutagen-modifying activity of caffeine was studied with the method of chromosomal aberrations in bone marrow cells of mice hybrids F1 CBAxC57BL/6. Caffeine per se was administered intragastrically or intraperitoneally, and in combination with mutagens--intragastrically. Mutagens injected intraperitoneally. Caffeine at doses of 10 and 100 mg/kg (single dose) and 10 mg/kg (five days) in parenteral administration and oral introduction failed to possess cytogenetic activity. In combination with mutagens caffeine (1, 10 and 100 mg/kg) had no effect on the cytogenetic activity of dioxydine (200 mg/kg/intraperitoneally) for a single coadministration, five-day pre or five-day coadministration. In combination with other mutagens under the same processing conditions caffeine at doses of 10 and 100 mg/kg significantly increased cytogenetic effects of cyclophosphamide (20 mg/kg) in the pretreatment of the animals and at the dose of 100 mg/kg significantly attenuated the cytogenetic effect of cisplatin (5 mg/kg) in single and repeated co-administration. Thus we have shown the absence of caffeine cytogenetic activity in vivo and showed the multidirectional effect of caffeine in doses far exceeding its daily consumption, to the manifestation ofcytogenetic effects of certain chemical mutagens in some modes of processing animals.
