abstract：:Visceral leishmaniasis is a severe and lethal disease caused by the protozoan parasites of the genus Leishmania. In areas where leishmaniasis is endemic, most infected individuals control the infection and remain asymptomatic; chemotherapy of visceral leishmaniasis restores some immunity which protects against relapse...

We now show an opposite thermal regulation of superoxide dismutase (SOD), consistent with a compensatory mechanism. Moreover, we demonstrate normal SOD and catalase levels in albino, oxygen-s...
