Serum nitrate levels of mice infected with of S. schenckii treated or not with NOS inhibitor

Infection/treatment	(μm)1 7th day	14th day	21st day
Non-infected/–	17 ± 6·7	24 ± 9·6	15 ± 9·7
Non-infected/N-Arg	12 ± 9·1	13 ± 8·7	12 ± 8·6
Yeast infected/–	255 ± 531	360 ± 59*	–
Yeast infected/N-Arg	27 ± 9·5	37·7 ± 10·2	33·6 ± 15

¹Data are represented as nitrate (μm). Nitrate levels were assayed on 7th, 14th and 21st day after infection with S. schenckii. Animals were daily treated with 50 mg/kg of N-Arg.

^*P < 0·05 compared to non-infected mice.
