Abstract:We analysed the metabolic rate of large individuals (LIs) and small individuals (SIs) (based on body weight) of 80-day-old specimens of Portunus trituberculatus injected with 40 mg/kg florfenicol (FLR). The results showed that FLR contents in the gills and hepatopancreas were higher in the SIs than in the LIs. The activities of erythromycin N-demethylase and 7-ethoxyresorufin-O-deethylase related to cytochrome oxidase P450 (CYP) were induced after FLR injection and showed a sizedependent pattern; however, no s… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
