Serum proteins of the Japanese quail, Coturnix coturnix Japonica

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1971
Abstract 1. 1. Fractionation of quail serum indicated two major protein components, one of which was an albumin fraction, and the other, a large molecular weight lipoprotein fraction. 2. 2. Quail serum albumin was physically and immunologically similar to chicken serum albumin. 3. 3.

Coturnix coturnix japonica

1971
The materials for the karyograms were prepared from feather pulp and embryonic tissue of coturnix quail secured through the courtesy of Dr. Hans Abplanalp, University of California, Davis. This colony originated from Japan. This species is one of the few among the birds so far described that have metacentric or submetacentric chromosomes recognizable ...

ANF binding sites in the heart of the quail (Coturnix coturnix japonica)

Peptides, 1993
The distribution pattern of rat [125I]-atrial natriuretic factor (ANF) binding sites in the cardiac regions of the Japanese quail was examined by in vitro quantitative autoradiography. Elevated ANF binding densities (519 +/- 121 fmol/mg protein) were found in the posterior vena cava, while lower binding levels (between 40 and 50 fmol/mg protein) were ...

The toxicity of dieldrin (HEOD) to Japanese quail (Coturnix coturnix japonica)

Toxicology and Applied Pharmacology, 1969
Abstract Dieldrin, purity >99% HEOD, has been given to Japanese quail (Coturnix coturnix japonica) at dietary concentrations of 0, 10, 20, 30, and 40 ppm. Mortality and dietary intake appeared to have been only marginally affected at 10 ppm, while the higher intakes gave progressively greater effects.

Hemiagenesis of the thyroid gland in the quail (Coturnix coturnix japonica)

Journal of Comparative Pathology, 1986
Hemiagenesis of the thyroid occurred in a closed population of Japanese quails. The unilateral gland was histologically normal, occurred most frequently in females, was heavier than individual pairs of glands and the birds showed no clinical effects. Comparative aspects are discussed.

Mate-choice copying in Japanese quail,Coturnix coturnix japonica

Animal Behaviour, 1998
We performed four experiments to examine effects on the mate choices of female Japanese quail, Coturnix coturnix japonica, of observing a male mate with another female. Each experiment was conducted in three phases: (1) a pre-test during which subject females were allowed to choose between two males with which to affiliate; (2) an observation phase, in

Effects of methyltestosterone on reproduction in the Japanese quail (Coturnix coturnix japonica)

Environmental Research, 2005
Although the hormone-mediated effects of the synthetic androgenic hormone methyltestosterone (MT) are well characterized in mammals, little is known about endocrine and other toxic effects on reproduction in birds. In a one-generation study, MT was administered to adult Japanese quail (12 pairs per group) at dietary dose levels of 0, 10, 50, and 110 ...

Response to Nutritional Deprivation in the Japanese Quail ( Coturnix Coturnix Japonica )

British Veterinary Journal, 1971
SUMMARY The accumulation of total tissue DNA as an index of cell number, and the weight/DNA ratio as an index of cell size were used to establish the effects of severe stunting imposed by malnutrition on cellular development and the permanence or reversibility of such stunting in Japanese quail.

Morphology of the cataract in albino mutant quails (Coturnix coturnix japonica)

Experimental Eye Research, 1985
Morphological changes in cataractous albino quail lens were studied by light microscopy. In some animals, a pin-head opacity in the lens could first be detected with the naked eye 2 months after hatching. Faint anterior or posterior cortical opacity was observed in many lenses at 3 months of age.

The acute phase response in Japanese quail (Coturnix coturnix japonica)

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2001
Experiments were conducted to determine the effect of injection of lipopolysaccharide (LPS, from S. typhimurium) or muramyl dipeptide (MDP, N-acetylmuramyl-L-ala-isoglutamine) in Japanese quail. Doses of MDP between 0.3 and 10 mg/kg body wt. had no effect on body temperature. In contrast, doses of 1.0-22.5 mg LPS/kg body wt.
