Embryo cryopreservation does not induce clear-cut anomalies at detectable rates, but several mechanisms exist for nonlethal damage during the freeze-thaw process, and the risk of moderate or delayed consequences has not been extensively investigated. In a long-term study including senescence, we compared cryopreserved and control mice for several… (More)
The previous studies from our laboratory reported that benzo(a)pyrene (Bap) influenced efflux transport of rhodamine 123 (Rho-123) by induction of P-glycoprotein (P-gp) in Caco-2 cells. The present study investigated whether induction of P-gp and the enhanced efflux transport of Rho-123 were caused by benzo(e)pyrene (Bep), which has a structure similar to… (More)
The main exposure pathway of benzo[a]pyrene (Bap) for humans is considered to be via the daily diet. The purpose of this study was to investigate the effect of BaP on the intestinal transport of chemicals mediated by P-glycoprotein (P-gp). The intestinal epithelial membrane transport of rhodamine-123 (Rho-123), a substrate of P-gp, was examined using a… (More)
In the rat, the autosomal recessive toothless (t1) mutation exhibits an acute form of osteopetrosis. This gene is not an allele of either ia or op that causes respectively, a transitory and acute form of the disease. Comparative radiographic study of t1/t1 and op/op mutants reveals some differences in respect to the size and shape of long bones. In contrast… (More)
In the "op" rat congenital osteopetrosis is a lethal condition. The management of this disease can be achieved by a single injection of a marrow cell suspension from a normal donor or by temporary parabiosis with a normal Rat, the latter procedure being less efficient than the former according to kinetic, roentgenographical and histological examinations.
The cure of osteopetrosis by allogenic bone marrow injection has been obtained in "op" mutant rat kept under cyclosporin A treatment. This immunosuppressive agent able to prevent the rejection of transplanted cells does not impair the propriety of these cells to restore the bone resorption process in this severe osteopetrotic form.
