l canavanine/atrophy

The effects of L-canavanine, a higher plant nonprotein amino acid, on the growth of a rat colon carcinoma were assessed. The 1 and 10% lethal dose values following a single s.c. injection in Fischer rats were 4.75 and 5.57 g/kg, respectively. Rats received s.c. injections of a 10% (w/v) tumor cell

The toxicity of L-canavanine was investigated because of its demonstrated potential as an antitumor drug. This natural product was only slightly toxic to Sprague-Dawley rats following a single sc injection: the LD50 was 5.9 +/- 1 8 g/kg in adult rats and 5.0 +/- 1.0 g/kg in 10-day-old rats.

Excessive production of nitric oxide (NO) as result of inducible nitric oxide synthase (iNOS) induction has been implicated in the pathophysiology of hemorrhagic shock. Our aim was to study the effect of iNOS inhibitors, L-canavanine (50mg/kg) and N(G)-nitro- L-arginine methyl (L-NAME, 10mg/kg) and
