An increase of uricogenesis in the Kuruma shrimp Marsupenaeus japonicus under nitrite stress.

Kuruma shrimp Marsupenaeus japonicus Bate, under the stress of 0.36 and 1.39 mM nitrite at 30 per thousand (parts per thousand, g kg(-1)) for 48 h, were examined for nucleotide-related compounds, specific activities of xanthine dehydrogenase (XDH), xanthine oxidase (XOD), and uricase.

Increase of uricogenesis in the kuruma shrimp Marsupenaeus japonicus reared under hyper-osmotic conditions.

Tissues of kuruma shrimp Marsupenaeus japonicus Bate (5.7+/-1.1 g) reared in salinities of 18, 26, 34 and 42 were examined for levels of nucleotide-related compounds, ammonia, urea and uric acid, and activities of xanthine dehydrogenase (XDH), xanthine oxidase (XOD) and uricase.
