I am studying the effects of cyclophosphamide in mice models and I injected 200 mg/kg, based on mice body weight, into a few mice that I had selected for the experiment. After 6 hours, I collected the serum and run an ALT assay on the samples. However, the levels of ALT are similar to the serum collected from mice injected with saline (controls). In a previous experiment, we had done two different timepoints (2 hours and 6 hours). In that experiment, the ALT levels for the 2 hours seemed to be higher than the 6 hours. Why would this be the case? Thanks!
Dear Sheba
I think that to evaluate the hepatotoxicity of CY you should wait at least 24 hours.
In this paper it was used 150mg/kg in rats and the levels of ALT, AST, ALP, GGT and LDH were really higher than controls after 24 hours of the administration in unique dose (See tables 2 and 3).
Best regards,
Thank you Alexander for your valuable advice! I will definitely look at what the paper suggests.
