Effects of methotrexate on rabbit oviducts and on cell cultures of bovine oviduct epithelium.

The influence of a local injection of 0.05 ml/kg weight of 8 mg/ml methotrexate (MTX) was evaluated in 6 rabbit oviducts and compared with saline injections to the contralateral oviducts. Cell cultures of bovine oviducts were incubated in vitro for 7 days and then incubated for 24 h with 100-nmol MTX.
