marek's disease in japanese quail -- a pathological, virological and serological study.experimental studies were performed to see whether japanese quail (coturnix coturnix japonica) are susceptible to jm strain of marek's disease virus (mdv). in three identical trials, a total of 120, one-day-old quail were inoculated intra-abdominally with 0.2 ml. of chicken blood infected with mdv (jm strain) and raised in fapp isolators. uninfected controls were inoculated with normal saline only and raised separately. during the 18-week post infection observation period, 65-80% of the infecte ...1975180503
calcium-binding protein and calcium absorption in the laying quail (coturnix coturnix japonica).a vitamin d3-dependent calcium-binding protein (cabp) has been found in the intestinal mucosa of japanese quail (coturnix coturnix japonica). this protein is similar, if not identical to that of the chick (gallus domesticus). a similar protein fraction appears also in uterine mucosa of laying quail. both intestinal and uterine cabp levels are higher in laying than in non-laying quails. uterine cabp was higher during egg shell formation than during uterine inactivity. the slight corresponding dif ...1976180508
regulation of intestinal calcium absorption in the laying quail: independent of kidney vitamin d hydroxylation.two experiments were carried out with laying quail (coturnix coturnix japonica) fed either cholecalciferol (40 mug/kg) or 1 alpha-hydroxycholecalciferol (8 mug/kg). recovery following vitamin d depletion, as indicated by egg production and shell deposition, was faster in quail fed 1 alpha-hydroxycholecalciferol than in those fed cholecalciferol. overall intestinal calcium absorption was higher in the 1 alpha-hydroxycholecalciferol-fed quail due to a higher absorption in the middle parts of the s ...1976182938
temporal analysis of cellular cytotoxicity and humoral factors during progession and regression of rous sarcomas in japanese quails.temporal appearance of cellular cytotoxicity and humoral activities including blocking and arming activities during the entire course of rous sarcoma development in japanese quails was examined by microcytotoxicity assay with comparison of animals bearing regressing tumors induced by a moderate dose of virus (regressors) and animals bearing growing tumors induced by a large dose of virus (progressors). cellular cytotoxicity of the spleen cells in regressors was detected in a biphasic pattern; th ...1976183034
spontaneous tumor regression: possible relationship to in vitro parameters of tumor immunity.evidence is discussed from three animal systems (shope papillomas in rabbits, moloney sarcomas in mice, schmidt-ruppin-rous sarcomas in japanese quail) that immune reactions can be important in spontaneous tumor regression. in vitro studies performed in these systems indicate that blocking serum factors can thwart cell-mediated immune responses and that "unblocking" antibodies are often found in animals whose tumors have regressed. to what extent spontaneous regressions of human neoplasms are du ...1976193017
continuous tissue culture cell lines derived from chemically induced tumors of japanese quail.several continuous tissue culture cell lines were established from methylcholanthrene-induced fibrosarcomas of japanese quail. the lines consist either of fibroblastic elements, round refractile cells or polygonal cells. they show transformed characteristics in agar colony formation and hexose uptake, and most are tumorigenic. their cloning efficiency in plastic dishes is not increased over that of normal quail embryo fibroblasts. the quail tumor cell lines do not produce endogenous avian oncovi ...1977194709
analysis of precursors to the envelope glycoproteins of avian rna tumor viruses in chicken and quail cells.immune precipitation with monospecific antiserum was employed to study the intracellular synthesis of viral glycoproteins gp85 and gp37. labeled gp85 and gp37 were detected from lysates of cells transformed with rous sacroma virus, strain b77, after long-term labeling with radioactive glucosamine or phenylalanine. immune precipitates prepared from lysates of cells pulse-labeled for a short time resulted in a glycoprotein of 92,000 molecular weight (gp92). this precursor was stable in b77-transfo ...1977195080
changes in phosphatidylinositol metabolism correlated to growth state of normal and rous sarcoma virus-transformed japanese quail cells.second-passage japanese quail embryo cell cultures, normal or quantitatively transformed by rous sarcoma virus, were investigated for phospholipid composition and metabolism. cells cultivated at low and high population density as well as in the presence or absence of serum, have been compared by chemical analysis and in pulse-chase experiments. no differences in the lipid compositions between the normal and the tumor cells or between cells under different culture conditions were detected. in no ...1977195714
suppression of radioiodide accumulation by the thyroids and oocytes of japanese quail with perrhenate.japanese quail, 50% inhibition of the 3-h accumulation of 131i occurred with 2.0 micromol kreo4, 2.2 micromol kclo4 and 13 micromol kscn for the growing oocytes, 1.7, 1.9 and 4.2 micromol for the thyroids of females and 0.20, 0.47 and 5.6 micromol for the thyroids of males. 2. kreo4 inhibition failed after 24 h in males and 36 h in females. 3. maxima at 6 h in the 131i curves for the plasma, the livers and the testes of kreo4-treated birds were attributed to retention of 131i in the plasma.1994196716
