Publikováno v: J. Cetacean Res. Manage.. 4:143-148

Since the mid-1970s, study has focused on reproductive biology of female bowhead whales, while little has been described for males. This study evaluates testicular morphology (mass and length) and histology in relation to body length to determine the

Publikováno v: Journal of Parasitology. 88:213-216

Cryptosporidium sp. was found in 3 out of 49 caribou (Rangifer tarandus) from northern Alaska. Segments of both the 18S ribosomal RNA and the heat shock protein genes were amplified from the caribou isolate and compared with that obtained from an iso

Publikováno v: The Journal of parasitology. 91(5)

Cryptosporidium spp. and Giardia spp. are protozoan parasites that are often associated with severe diarrheal disease in a variety of mammals. Although these parasites have been extensively studied in terrestrial ecosystems, little is known about eit

Oxytetracycline residues in channel catfish: a feeding trail

Autor: T M, O'Hara, A, Azadpour, J, Scheemaker, P D, Gerard

Publikováno v: Veterinary and human toxicology. 39(2)

Channel catfish were fed a sinking diet containing 3% oxytetracycline (OTC) once-a-day (SID) or twice-a-day (BIO) for 2 and 3 weeks and liver and muscle residues were determined. HPLC analysis for muscle indicated mean OTC levels of 0.052 ppm (0-0.15

Liver and kidney concentrations of zinc, copper and cadmium in channel catfish (Ictalurus punctatus): variations due to size, season and health status

Autor: C P, McCoy, T M, O'Hara, L W, Bennett, C R, Boyle, B C, Lynn

Publikováno v: Veterinary and human toxicology. 37(1)

Significant differences in liver and kidney concentrations of zinc (Zn), copper (Cu) and cadmium (Cd) were detected in normal Mississippi farm-raised channel catfish (Ictalurus punctatus) collected at different times of the year. These seasonal diffe

Publikováno v: Fundamental and applied toxicology : official journal of the Society of Toxicology. 14(3)

The joint hepatotoxicity of CCl4 and CHCl3 or TCE in male CD rats following simultaneous oral administration has been investigated. Rats with chronic indwelling arterial cannulas were administered a single oral dose of CCl4 and CHCl3 or CCl4 and TCE

A CCl4/CHCl3 interaction study in isolated hepatocytes: selection of a vehicle

Autor: T M, O'Hara, J F, Borzelleca, E C, Clarke, M A, Sheppard, L W, Condie

Publikováno v: Fundamental and applied toxicology : official journal of the Society of Toxicology. 13(3)

Emulphor, ethanol, and dimethyl sulfoxide (DMSO) were evaluated as vehicles in studying the toxicity of CCl4 and CHCl3 in isolated hepatocytes. The appropriateness of the vehicle was determined by evaluating the following parameters: solubility of CC
