Abstract

Effects of Naphthalene which is a carcinogen on changes of DNA and RNA quantities were studied with acridine orange stained cells under a confocal laser scanning microscope. It was found that DNA and
RNA in amoebae nucleus and cytoplasm, reared in 0 (control), 3 and 8.85 mg/l (24h-LD₅₀) at 0 and 12 h. showed a statistically significant difference (p<0.05). The more naphthalene concentrations and larger incubation periods had greater effects on DNA and RNA decreases in amoebae nucleus and cytoplasm.
