Abstract
Glavni cilj rada je bio istražiti navodnu ulogu adipokinetičkog hormona u antioksidativnom odgovoru kod kukca Pyrrhocoris apterus tretiranog otrovom Habrobracon hebetor. Praćeni su biomarkeri oksidativnog stresa: sadržaj protein karbonila te aktivnosti glutation S-transferaze i katalaze. Kvantificiran je ukupan sadržaj adipokinetičkog hormona u središnjem živčanom sustavu. Ubrizgavanje otrova u plamenu stjenicu uzrokovalo je smanjenje sadržaja protein karbonila u hemolimfi ali je povećalo karbonilaciju probavila. Ko-tretmanom otrova i Pyrap-AKH sadržaj protein karbonila u hemolimfi se vratio na kontrolnu razinu ali se povećao iznad kontrolne razine u probavilu. Otrov je uzrokovao povećanje aktivnosti glutation S-transferaze u probavilu i umanjio aktivnost katalaze. Nakon kotretmana aktivnosti glutation S-transferaze i katalaze nisu se promjenile u odnosu na tretman otrovom što je neočekivano. Kvantifikacija Pyrap-AKH pokazala je povišene razine adipokinetičkog hormona u središnjem živčanom sustavu nakon ubrizgavanja otrova. Mišići tjelesne stjenke nisu reagirali na djelovanje otrova. Očito je da otrov uzrokuje oksidativni stres kod plamene stjenice ali rezultati nakon ko-tretmana otrova i adipokinetičkog hormona nisu potvrdili očekivanja
Abstract (english)
The main goal of the study is to explore this putative role of adipokinetic hormone in antioxidative stress response in the firebug Pyrrhocoris apterus body poisoned by Habrobracon hebetor venom. Oxidative stress biomarkers were monitored: protein carbonyl content and activity of glutathione Stransferase and catalase. Adipokinetic hormone level was quantified in central nervous system. Injection Habrobracon hebetor venom into Pyrrhocoris apterus body caused decrease in protein carbonyl content in hemolymph but increased carbonylation in midgut. When co-treated with venom and Pyrap-AKH, protein carbonyls returned to control level in hemolymph but increased above control level in midgut. Venom elicited activity of glutathione S-transferase in midgut but decreased catalase activity. After co-treatment glutathione S-transferase and catalase activity did not change compared to venom treatment which was not expected. Quantification of Pyrap-AKH showed elicited adipokinetic level in central nervous system after venom injection. Body wall muscles were not affected by venom. It is apparent that venom elicited oxidative stress in P. apterus but co-application of venom and adipokinetic hormone did not match the expectation
