Abstract
Istraživan je učinak aluminija u laboratorijskim uvjetima na planariju Polycelis felina (Daly.). Planarije su tretirane s 21 koncentracijom aluminijevog sulfata oktadekahidrata u trajanju od pet dana i uspoređene s tri kontrolne skupine. Korištene su mikroskopijske, histološke i morfometrijske metode. Rezultati su pokazali različite morfološke promjene na tijelu planarija kao i promjene u ponašanju: različite depigmentacije, poremećaje u pokretanju, uvrtanje pojedinih dijelova tijela, sporo reagiranje na mehanički podražaj, kontrakcije tijela i mortalitet. Histomorfometrijskom analizom pokazane su promjene u veličini i broju neoblasta, retikularnih stranica kao i promjene u epitelnim stanicama i segmentima epitela, parenhimu i mišićnom sloju. Pri koncentraciji od 200 mg AL/L planarije su počele pokazivati blage, ali značajne promjene. Koncentracija 600 mg AL/L pokazala se prijelaznom koncentracijom prilikom koje su uočene intenzivne subletalne promjene u ponašanju, te morfološkoj i histološkoj strukturi virnjaka. Koncentracija 1100 mg AL/L dovela je do ireverzibilnih promjena i LC50. Sniženi pH u kontrolnih skupina nije izazvao promjene. Uzimajući u obzir visoki LC50, korištene koncentracije ne predstavljaju stvarnu prijetnju populacijama virnjaka u prirodnom okolišu, nego pokazuju opseg mogućih poremećaja i oštećenja u okolišu s potencijalno visokim koncentracijama aluminija.
Abstract (english)
The effect of aluminium on planarian Polycelis felina (Daly.) in laboratory conditions was studied. The planarians were treated with 21 concentration of aluminium sulphate for five days and compared to 3 control groups of animals. Microscopical, histological and morphometric methods were used. The results showed distinguished morphological changes on the planarian body as well as behavioral changes: various depigmentations, disordered locomotion, twisting of the body parts, hardly reacting to the mechanical stimuli, body contractions and mortality. Histomorphometric analyses showed changes in the size and number of neoblasts and reticular cells. Changes in epithelial cells and segments, parenchyma and muscular layer were also noticed. At 200 mg AL/L planarians started to show mild, but significant changes. Concentration of 600 mg AL/L presented concentration threshold with distinct changes in behavior, morphological and histological structure of planarians. Concentration of 1100 mg AL/L caused irreversible changes and LC50. Lowered pH did not cause changes in control groups. Considering high LC50, the used concentrations of aluminium presented no actual environmental threat to planarian populations in nature, but showed the extent of disturbances and damages in a possible concentrated Al-environment.
