Cytotoxicity phase of diethylnitrosamine-induced hepatic neoplasia in medaka.

Adult Oryzias latipes were exposed to 50 mg of diethylnitrosamine per liter of water for 5 wk and then transferred to clean water for an additional 15 wk. Response of the liver during the first 6 wk were analyzed by enzyme histochemistry and by high-resolution light and transmission electron microscopy. After 1 wk, cytotoxicity was apparent at the light microscopic level by piecemeal necrosis a...

Growth inhibition in Japanese medaka (Oryzias latipes) fish exposed to tetrachloroethylene.

A recent study in our laboratory has demonstrated that tetrachloroethylene (TCE) is acutely toxic to Japanese medaka (Oryzias latipes) larvae with a 96 hr-LC50 of 18 (17-19) mg/mL (Spencer et al., 2002). In the present study we hypothesize that TCE exposure induces a developmental effect in Japanese medaka. Growth and age specific sensitivity of Japanese medaka larvae were studied with four age...

Reproductive Success and Behavior of Japanese Medaka (oryzias Latipes) Exposed to 4-tert-octylphenol

Japanese medaka (Oryzias latipes), a small freshwater fish used extensively to investigate sexual differentiation and development, were exposed to octylphenol (OP), a known estrogen agonist, to assess its impact on reproductive success. Male and female medaka were exposed to nominal concentrations of 10, 25, 50, and 100 mg/L OP from 1 d posthatch to 6 months posthatch. In reproduction trials in...

Feminization of female leukophore-free strain of Japanese medaka (Oryzias latipes) exposed to 17beta-estradiol.

The recently developed female leukophore-free (FLFII) strain of Japanese medaka (Oryzias latipes) carries DNA markers for the identification of genotypic sex. Information regarding genotypic sex is useful for tests in which endocrine-disrupting compounds may masculinize or feminize fish. In the present study, methods were developed to automate DNA extraction and profiling for rapid determinatio...

Life-cycle toxicity of 4-nonylphenol to medaka (Oryzias latipes).

We studied the chronic effects of 4-nonylphenol (4-NP) on reproductive status of medaka (Oryzias latipes) over two generations of continuous exposure. The exposure study of the parental (F0) medaka was begun on embryos within 24 h postfertilization and continued with monitoring through embryological development, hatching, posthatch survival, growth, sexual differentiation, and reproduction unde...
