Abstract. The aim of the present study was to examine potential protective effects of methyl N-methylanthranilate (M) and isopropyl N-methylanthranilate (I) in a rat model of acute intoxication with carbon tetrachloride (CCl4) by tracking the changes in liver morphology and function. Serum transaminase and bilirubin were significantly elevated in animals treated with CCl4 alone. A pretreatment with M and I prior to the administration of CCl4 significantly prevented the increase of serum levels of liver damage markers. Histopathological evaluation of the livers of the test animals also revealed that M and I reduced the incidence of liver lesions. Our experiments showed that both M and I possess protective effect in CCl4-induced liver damage in rats. The results are of interest due to the presence of natural or synthetic M in the human diet.
Key words: carbon tetrachloride, methyl and isopropyl N-methyl anthranilates, liver, transaminases
UTICAJ METIL- I IZOPROPIL-N-METILANTRANILATA NA UGLJEN-TETRAHLORIDOM IZAZVANE PROMENE U FUNKCIJI I MORFOLOGIJI JETRE PACOVA
U ovom radu ispitivano je potencijalno protektivno dejstvo metil N-metilantranilata (M) i izopropil N-metilantranilata (I) u modelu akutne intoksikacije pacova sa ugljen-tetrahloridom (CCl4) praćenjem promena u morfologiji i funkciji jetre. Kod životinja tretiranih sa samo CCl4 značajno su bile povećane vrednosti transaminaza i bilirubina u serumu. Pretretman sa M i I značajno je umanjio porast serumskih markera oštećenja jetre. Patohistološka analiza tkiva jetre pokazala je da M i I smanjuju stepen oštećenja jetre. Ovaj eksperiment je pokazao da i M i I imaju protektivno dejstvo kod oštećenja jetre izazvanog CCl4. Ovi rezultati su značajni zbog prisustva prirodnog ili sintetskog M u ljudskoj ishrani.
