Abstract

The lethal dietary toxicity of dieldrin was estimated repeatedly during 8 years of testing young bobwhites (Colinus virginianus), Japanese quail (Coturnix c. japonica), ring-necked pheasants (Phasianus colchicus), and mallards (Anas platyrhynchos). Toxicities, quantified as 8-day LC50 values (5 days on toxic diet, followed by 3 days of untreated feed), were estimated at least 18 times per species. Average dietary LC50 values (ppm) and their 95% confidence limits for 14-day-old quail and 10-day-old pheasants and mallards were: bobwhite, 38 (34?42); Japanese quail, 61 (58?64); ring-necked pheasant, 56 (53?59); and mallard, 179 (163?195). No time-related changes were detected in LC50 values for any of the species.

In vivo/in vitro comparison of pharmacokinetics and pharmacodynamics of 3,3',4,4'-tetrachlorobiphenyl (PCB77)

The rat hepatoma cell line, H4IIE, serves as a useful tool to assess potential biological effects such as induction of cytochrome P4501A1 expression. The objectives of this study were twofold: to investigate the kinetic time course and dosimetry of PCB77 in rat hepatoma cells dosed with PCB77 and in liver of rats given ip doses of PCB77, and to compare in vitro and in vivo P4501A1 enzyme induction responses. For the 4-day time–course study, H4IIE cells were exposed with two doses of [ 14 C]PCB77 (0.9 and 3 μg/plate) and harvested at 15 and 30 min, 1, 2, 4, 8, and 12 hr, and 1, 2, 3, and 4 days. PCB77-derived radioactivity was detected in the cells as early as 15 min postdosing. For the dose–response study, the cells were dosed with various concentrations of PCB77 (0.00316–5.37 μg/plate) and harvested on Day 3 since ethoxyresorufin O -deethylase (EROD) activity in vitro reached its maximum on the third day postdosing. Time–course and dose–response studies revealed that only 1–3% of the total delivered dose was found in the cells, with the remainder in the media and adhering to the culture plates. For the dose–response study in vivo, male Fischer rats were dosed with a single ip injection of various concentrations of PCB77 (0.1–50 mg/kg body wt) and euthanized on Day 3. PCB77-derived radioactivity and EROD induction in vivo were measured. When EROD activity and PCB77-derived radioactivity in the rat hepatoma cells and in the rat liver were compared on an equivalent weight basis, there was a significant correlation ( r 2 = 0.985) between them. Prior to this study, no information on quantitative dosimetry and EROD activities of PCB77 has been reported to validate the in vitro assay with in vivo data.

Embryotoxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD): Theembryonic vasculature is a physiological target for TCDD-induced DNA damage and apoptotic cell death in medaka (Orizias latipes)

Vertebrate embryos are extremely sensitive to environmental contaminants known as planar halogenated hydrocarbons (PHHs). The physiological targets that mediate PHH-induced embryotoxicity are not known. We have characterized embryotoxicity in medaka ( Orizias latipes ) caused by 2,3,7,8-tetrachlorodibenzo- p -dioxin (TCDD), the prototypic PHH. DNA degradation in cells of the embryonic vasculature and loss of functional integrity of the medial yolk vein were demonstrated in TCDD-exposed embryos. Pharmacological intervention with piperonyl butoxide inhibited TCDD-induced DNA degradation, restored the functional integrity of the medial yolk vein, and protected against the embryotoxicity of TCDD. Treatment of TCDD-exposed embryos with the antioxidant N -acetylcysteine also provided significant protection against the embryotoxicity of TCDD. These results demonstrate that DNA damage and consequent cell death in the embryonic vasculature are key physiological mediators of TCDD-induced embryotoxicity.

Subchronic organophosphorus ester-induced delayed neurotoxicity in mallards

Eighteenweek-old mallard hens received 0, 10, 30, 90, or 270 ppm technical grade EPN (phenylphosphonothioic acid O -ethyl- O -4-nitrophenyl ester) in the diet for 90 days. Ataxia was first observed in the 270-ppm group after 16 days, in the 90-ppm group after 20 days, in the 30-ppm group after 38 days; 10 ppm failed to produce ataxia. By the end of 90 days all 6 birds in the 270-ppm group exhibited ataxia or paralysis whereas 5 of 6 birds in the 90-ppm group and 2 of 6 birds in the 30-ppm group were visibly affected. Treatment with 30 ppm or more resulted in a significant reduction in body weight. Brain neurotoxic esterase activity was inhibited by averages of 16, 69, 73, and 74% in the 10-, 30-, 90-, and 270-ppm groups, respectively. Brain acetylcholinesterase, plasma cholinesterase, and plasma alkaline phosphatase were significantly inhibited as well. Distinct histopathological effects were seen in the 30-, 90-, and 270-ppm groups which included demyelination and degeneration of axons of the spinal cord. Additional ducks were exposed in a similar manner to 60-, 270-, or 540-ppm leptophos (phosphonothioic acid O -4-bromo-2,5-dichlorophenyl- O -methylphenyl ester) which resulted in similar behavioral, biochemical, and histopathological alterations. these findings indicate that adult mallards are probably somewhat less sensitive than chickens to subchronic dietary exposure to organophosphorus insecticides that induce delayed neurotoxicity.
