Abstract

Lipids and proteins in the Rathke's gland secretions of the North American mud turtle ( Kinosternon subrubrum , Kinosternidae) were analyzed by gas chromatography-mass spectrometry (GC-MS) and SDS-polyacrylamide gel electrophoresis (SDS-PAGE), respectively. Analysis by GC-MS indicates 2,3-dihydroxypropanal and C 3 –C 24 free or esterified fatty acids. Analysis by SDS-PAGE indicates a major protein component with an approximate molecular mass of 60 kDa and minor components ranging from ca. 23 to 34 kDa. The major component of K. subrubrum glandular secretions exhibits a mobility that matches that of the Kemp's ridley sea turtle ( Lepidochelys kempi , Cheloniidae), suggesting that these proteins are evolutionarily conserved.

Seasonal variation in diagnostic enzymes and biochemical constituents of captive northern bobwhites and passerines

1. A variety of biochemical measurements were taken periodically in captive northern bobwhite ( Colinus virginianus L.), European starlings ( Sturnus vulgaris L.), red-winged blackbirds ( Agelaius phoeniceus L.) and common grackles ( Quiscalus quiscula L.) to determine whether baseline values remain sufficiently stable throughout the year for general clinical use in the absence of concurrent control specimens. 2. Variables included whole blood hemotacrit and hemoglobin, plasma lactate dehydrogenase, α-hydroxybutyrate dehydrogenase, aspartate aminotransferase, alinine aminotransferase, creatine kinase, butyrylcholinesterase, alkaline phosphatase, glucose, albumin, total protein, creatinine, urea nitrogen, uric acid, cholesterol, and triglycerides, and brain acetylcholinesterase. Butyrl- and acetylcholinesterase were included because of their specific uses in toxicology. 3. Significant seasonal differences were detected for each of the variables except brain acetylcholinesterase in at least one of the species. Significant species differences were detected during at least one season for all of the variables measured. 4. All species were maintained outdoors, but only northern bobwhites came into reproductive condition and showed sex-differences in the clinical variables during their normal breeding season. 5. It was concluded that reference values for the 18 clinical variables measured could be calculated from our data for adult specimens of the species studied, and that results for one species cannot be extrapolated with certainty to any other species. 6. Estimated normal bounds for each of the 18 variables measured by commonly used clinical procedures are presented for reproductively quiescent northern bobwhites, European starlings, red-winged blackbirds, and common grackles.

Thymocyte plasma membrane of the rainbow trout, Salmo gairdneri : Associated immunoglobulin and heteroantigens

1. Thymic lymphocytes of the rainbow trout, S. gairdneri were disrupted and a plasma membrane containing fraction isolated by differential and buoyant density centrifugation. 2. Radioiodine introduced into the membrane by the lactoperoxidase catalyzed reaction and immunoglobulin (identified by radioimmunoassay with monoclonal antibody) both copurified in the plasma membrane fraction. 3. Rabbit antibody raised to the plasma membrane fraction showed a strong reaction with trout lymphocytes in immunofluorescence, was mitogenic for trout lymphocytes, and recognized lymphocyte membrane heteroantigens of molecular weight > 70,000 in the thymus and 45,000–95,000 in the head kidney.

Reassociation and hybridization properties of DNAs from several species of fish

Reassociation and hybridization properties from spectrophotometric studies of DNAs from 10 species of fish indicate: 1. Great diversity in the amounts of repeated sequences in the genomes of different species - more specialized fish had less redundancy. 2. Large differences in the complexities of the DNAs - more specialized fish had less information. 3. Little homology between sequences of remotely related species but substantial homology between sequences of closely related species.
