Cyclosporine,knownasananti-inflammatorydrug,is usedtotreatmanyinflammation-associateddiseases.

Objectives: Inthisstudy,cyclosporinewasselectedtoinhibitthescorpiontoxineffectsonratorgans.

Methods: Thisexperimental studywas conductedinthe RaziVaccine andSerum ResearchInstitute, AgriculturalResearch EducationandExtensionOrganization,Karaj,Iran,fromJunetoNovember2019.Fiftymaleratswererandomlydividedintofivegroupsof 10,includingthecontrol(10mg/kgoliveoili.p),M.eupeusvenom(10mg/kgi.p.),cyclosporine10mg/kg(venom10mg/kgfor30min i.pfollowedbycyclosporine10/kgmgfor7dayi.p.),cyclosporine20mg/kg(venom10mg/kgfor30mini.pfollowedbycyclosporine 20mg/kgfor7dayi.p.),andcyclosporine30mg/kg(venom10mg/kgfor30mini.pfollowedbycyclosporine30mg/kgfor7dayi.p.).

Aftertreatmentwithcyclosporine,theliverandkidneyfunctionwasanalyzedbycalculatingsomebiochemicalenzymes,including serumglutamate-pyruvatetransaminase(SGPT),serumglutamicoxaloacetictransaminase(SGOT),nitricoxide(NO),interleukin-2 (IL-2), malondialdehyde(MDA), creatinine, andurea viaELISAand spectrophotometry.

Then, to determinethe rateof apoptosis in tissue,terminaldeoxynucleotidyltransferase-mediateddUTPnick-endlabelingmethodwasdone.

No significant difference was observed between the cyclosporine and venom groups in NO and IL-2.

Conclusions: Cyclosporineatadoseof 30mgwasabletodecreaseinflammatoryresponsesandinduceapoptosisrate.
