Peripheral blood was drawn from 3 healthy cows, and cultured in duplicate for 72 h in RPMI 1640 medium plus 10 % FBS, L-glutamine, antibioticantimicotic, and Concanavalin-A. After 36 h from the initiation, BrdU (Sigma) was added to the cultures, respectively at 10 ?g/ml and 300 ?g/ml (f.c.). Slides were\nstained with acridine orange solution (0.010 % in Sorensen buffer, pH07.0). 20 metaphases were analyzed for each animal, for each dosage, with a total of 3,523 chromosomes. The mean rate of SCE/cell was 5.85\u00B12.71 at the dosage of 10 ?g/ml while it increased up to 33.93\u00B1 13.03 at the dosage of 300 ?g/ml. The fraction of chromosomes 'with' exchanges was only 9%at the dosage of 10, while it increased up to 41.51 % at the dosage of 300. The exchanges (SCEs) observed at 10 ?g/ml were of type 1 (8.84 %), type 2(0.42 %) and type 3 (0.03 %), whereas at 300 ?g/ml many more exchanges were observed as follows: type 1 (29.10 %), type 2 (9.54 %), type 3 (1.98 %), type 4 (0.77 %), type 5 (0.09 %) and type 6 (0.03 %). By increasing the BrdU final concentration from 10 to 300 ?g/ml , the total number of exchanges visualized rised from 354 at 1,462 (4.13 times). These results encourage further insights into the SCE studies at high dosages of BrdU in order to better characterize the\ngenome stability in the livestock species and breeds engaged in animal production.\nAcknowledgements: This work was supported by the RARECA- PSR 214 project of the Campania Region (Italy).."@en ; prodottidellaricerca:prodottoDi istituto:CDS083 , modulo:ID7238 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA9036 , unitaDiPersonaleInterno:MATRICOLA14539 , unitaDiPersonaleInterno:MATRICOLA15232 . ns11:ID238329 pubblicazioni:rivistaDi prodotto:ID190954 .
