| immunohistochemistry of the hypothalamic neuropeptides and anterior pituitary cells in the japanese quail. | the pars distalis of the avian adenohypophysis consists of well-defined cephalic and caudal lobes which are distinct in their cellular constituents. immunocytochemical investigations on the pituitary hormones of the pars distalis of the japanese quail reveal five types of secretory cells, adenocorticotropin (acth) cells, prolactin (prl) cells, thyroid-stimulating hormone (tsh) cells, growth hormone gh (sth) cells, and fsh/lh (gonadotropic) cells. the acth cells, tsh cells, and prl cells are rest ... | 1984 | 6084043 |
| agglutinin responses to salmonella pullorum in japanese quail selected for plasma cholesterol response to adrenocorticotropin and a model describing the dynamics of the response. | japanese quail from the s16 generation of lines selected for high (hr) and low (lr) plasma cholesterol response to adrenocorticotropin (acth), and the randombred control line (c) from which the selected lines had been derived, were immunized with a heat-killed salmonella pullorum antigen. plasma from blood samples taken at 0,5,8, and 12 days postimmunization was titered for total agglutinin levels. a quadratic equation and its first derivative, calculated for each bird, produced mean values by l ... | 1984 | 6091085 |
| increased transcription of the c-myc oncogene in two methylcholanthrene-induced quail fibroblastic cell lines. | the expression of three c-onc genes (c-erb, c-myc, c-myb) was investigated in five cell lines established from fibrosarcomas induced with 20-methylcholanthrene (mca) of japanese quails. these cell lines showed low levels of the three c-onc genes, with the exception of two cell lines that accumulated moderate (mcaq 1-4) and large amounts (mcaq3-5) of c-myc rna. molecular cloning and restriction endonuclease analyses indicated that expression of c-myc in these two cell lines were not associated wi ... | 1984 | 6094223 |
| oncogenecity of an avian erythroblastosis virus in mutant strains of japanese quails. | the susceptibility of 12 mutant strains of japanese quails to the r strain of avian erythroblastosis virus (aev) was examined. three strains, sbpp, pnn and cwe, showed high susceptibility and developed various types of tumors including erythroblastosis, hemangioma and myeloblastic leukemia. in relatively resistant we strain, increased incidence and various types of tumors were observed by modification of host conditions. these results indicate pluripotential oncogenicity of aev in quails as well ... | 1984 | 6094891 |
| avian gonadotropin receptors: a comparative view. | avian testicular receptors for gonadotropins show a species-specificity similar to mammalian receptors for the binding affinity to gonadotropins of various origins. in the affinity-capacity relationships, avian fsh receptors are classified in the same group with chelonians, that is, they exhibit relatively low affinity and high capacity. fsh receptors of the japanese quail resemble the rat receptor with respect to the temperature-dependence of affinity in the low-temperature range, but also rese ... | 1984 | 6097628 |
| the neuroendocrine control of gonadotrophin release in the japanese quail. iii. the role of the tuberal and anterior hypothalamus in the control of ovarian development and ovulation. | reproduction in the japanese quail (coturnix coturnix japonica), as in many other species, is controlled by the length of the daily photoperiod. the present experiments have investigated the neuroendocrine regulation of both the photoperiodically induced 'tonic' gonadotrophin secretion, which causes the development and maintenance of the ovary, and the 'cyclic' surge release of luteinizing hormone (lh), which stimulates ovulation. areas within the anterior and tuberal hypothalamus were destroyed ... | 1980 | 6102391 |
| the energy costs of temperature regulation in birds: the influence of quick sinusoidal temperature fluctuations on the gaseous metabolism of the japanese quail (coturnix coturnix japonica). | 1. quick sinusoidal temperature fluctuations (constant average 10 degrees c) cause an increase in metabolism in comparison to an invariable constant ambient temperature of the same dimension. 2. at the observed mean value of 10 degrees c metabolism is increased by 0.8% per 1 k/hr based on the values of resting metabolic rate (correlation: m = 53.5 + 0.445 ta, m in j/k g hr, ta = ambient temperature change in k/hr) and 0.6% based on the values of activity metabolism (m = 70.4 + 0.425 ta). 3. the ... | 1982 | 6120786 |
| immunoreactive neuropeptide systems in avian embryos (domestic mallard, domestic fowl, japanese quail). | in embryos of the domestic mallard, domestic fowl, and japanese quail vasotocin-, mesotocin-, luliberin (lhrh)-, met-enkephalin-, corticotropin-, and somatostatin-immunoreactive perikarya and fiber formations were visualized at different incubation stages by means of the pap technique (sternberger 1979). the most striking results were: (1) vasotocin-, mesotocin-, and luliberin-immunoreactive systems display, up to the late embryonic period, morphological features most probably related to a neuro ... | 1982 | 6121629 |

| [growth dynamics of housefly larvae on organic wastes in a biological human life support system]. | the time-course of the growth of musca domestica larvae on organic wastes (human and japanese quail excrements) was studied as a function of the egg density. an increase in the density of the substrate contamination reduced the weight of pupae and iii instar larvae. the density effect in the case of quail excrements was seen earlier than in the case of human excrements. the larval weight on quail excrements was much lower than on human excrements, the density of substrate contamination being equ ... | 1982 | 6129345 |
| changes in glucose and lipid metabolism in starved or starved-refed japanese quail (coturnix coturnix japonica) in relation to fine structure of liver cells. | 1. metabolic response of adult quail to fasting or refeeding was studied by measuring the main blood and hepatic metabolites. moreover, the fine structure of hepatocytes in these physiological conditions was described. 2. starvation or refeeding did not affect glycemia in male as in female quails. 3. fasting had no effect on plasma free fatty acids in female quails, whereas plasma triglycerides were markedly decreased. 4. in fasted quails, there was an active ketogenesis with a high 3-hydroxybut ... | 1983 | 6132730 |
| erythrocytic phosphates and flying activity in birds. | 1. the intraerythrocitary organic phosphates in different avian species (sturnus vulgaris, apus apus, gallus gallus domesticus, coturnix coturnix japonica and columba livia) were analyzed by ionic exchange chromatography. the chromatograms of these species revealed the presence of adp, atp, gtp, ipp and inorganic phosphate. 2. the main organic phosphates (atp and ipp) and the inorganic phosphate were also evaluated, directly, in other specimens. the ipp levels were very similar in all species; h ... | 1983 | 6132731 |
| inter and intraspecies genetic differences in survival to an acute carbon monoxide challenge in mice, rats, guinea-pigs, quails and chickens. | 1. groups of small laboratory vertebrates, of both sexes, have been submitted to an acute carbon monoxide challenge, close to a ld50. 2. an interspecific classification, from low to high co sensitivity, gives: guinea-pigs-mice-chicks-rats-quails. 3. interstrain statistical differences were observed in all species, with the exception of guinea-pigs. furthermore, among two selected genotypes of japanese quails, one was resistant to acute nitrogen hypoxia and to carbon monoxide intoxication and the ... | 1983 | 6132741 |
| rabies vaccine prepared from the virus grown in japanese quail embryo cell cultures. | fixed rabies virus strain mniivp-74 was grown in japanese quail embryo cell cultures, concentrated by ultrafiltration and inactivated with beta-propiolactone. the resulting vaccine was markedly antigenic and immunogenic for laboratory animals. human volunteers injected with 2.0 ml vaccine on days 0, 3, 7, 14, 30 and 90 exhibited more intensive and longer antibody production than those injected daily for 14 days. | 1983 | 6133431 |
| cutaneous water evaporation--i. its significance in heat-stressed birds. | in a comparative study on avian cutaneous evaporation, two species of phasianidae, japanese quail coturnix coturnix japonica and chukar partridge alectoris chukar, and three species of columbidae, palm dove streptopelia senegalensis, collared turtle dove streptopelia decaocto and rock pigeon columbia livia, were investigated. the skin resistance to vapor diffusion (rs) and cutaneous water loss (cwl) were studied in these birds exposed to air temperatures (ta) between 20 and 52 degrees c. the ski ... | 1983 | 6136378 |
| daily fluctuations of peripheral metabolism of corticosterone in male japanese quails: a dynamic approach to the development of plasma corticosterone daily rhythm. | an ultradian rhythm was found in the daily variation of the parameters concerning the peripheral metabolism of corticosterone in sexually mature male japanese quails. the period of this rhythm was eight hours; three peaks and minima were found in the daily fluctuation of metabolic clearance rata and an antiphysed rhythm in the biological half-life as well as in tetrahydrocorticosterone/corticosterone conversion rata. the findings emphasize the importance of the peripheral metabolism in developin ... | 1983 | 6136384 |
| iron mobilization in estrogenized male quail. | a single diethylstilbestrol (des) injection (5 mg des/100 g body wt) was administrated to several lots (three specimens each) of adult male quail (coturnix coturnix japonica). the birds were sacrificed 24, 48, 72 and 96 hr after the des injection. a significant increase in liver weight and a clear drop in the hemoglobin concentration were observed after 24 hr. later, a progressive rise was observed in plasma iron, total iron binding capacity, plasma copper and the phosphoprotein (vitellogenin), ... | 1984 | 6147235 |
| magnesium deficiency in the japanese quail. | morphological effects of magnesium deficiency on liver cells and general aspects of its influence on the metabolism were investigated in young quails. magnesium deficiency was characterized by a depressed growth, a high mortality rate, a decrease in hematocrit and magnesium and calcium plasma concentrations. magnesium deficiency reduced the magnesium concentration in heart by 44%, but did not affect the concentration in liver. ultrastructural aspect of liver parenchymal cells revealed that the n ... | 1984 | 6148188 |
| post-hatching thyroid development and body growth in precocial vs altricial birds. | thyroid growth, thyroid function and body growth are markedly different in developing precocial japanese quail and altricial ring doves despite comparability in incubation period, hatchling size, adult body weight and adult serum thyroid hormone concentrations. in quail thyroid activity is high during the perinatal period, declines shortly after hatching, then gradually attains adult function. in contrast, in doves, there is no perinatal peak of thyroid activity. thyroid function is low at hatch ... | 1984 | 6149037 |
| peptidergic pathways in the avian brain. | the results obtained by topographical studies on the immunoreactive peptide systems in the embryonic and adult avian brain (domestic fowl, domestic mallard, pigeon, japanese quail, and zebra finch) can be realized only by means of phylogenetical comparisons. the comparative studies mainly demonstrate a fascinating constancy of the immunological properties and the spatial distribution of the neuropeptides. independent of the development of the neopallium, and the increasing cerebral complexity, t ... | 1984 | 6151578 |
| effect of 3-hydroxy-3-methylglutaric acid on cholesterol metabolism in female japanese quail. | the compounds 3-hydroxy-3-methylglutaric acid (hmg) and hmg diethylester were administered to laying coturnix hens to evaluate their potential in reducing yolk cholesterol concentrations. the administration of hmg did not produce consistent differences from controls in tissue levels of either cholesterol or triglycerides. the administration of hmg diethylester appeared to increase the de novo synthesis of cholesterol and the mobilization of cholesterol from liver to serum, as assayed by the upta ... | 1980 | 6158036 |
| developmental changes in the presence of specific chicken fetal-leukemic antigen determinants in the chicken, japanese quail, and the interspecific hybrid. | the pattern and timing of expression of chicken fetal-leukemic antigen (cfa) on peripheral red blood cells (rbcs) is reported for specific periods of postembryonic development in chickens, japanese quail, and quail-chicken hybrids. individual cfa determinants were lost from the peripheral rbcs of chickens and hybrids at specific times of development. the sequential pattern of phasing in these sources suggests that at least some of the cfa determinants may be expressed independently on the cell s ... | 1980 | 6158037 |
| an analysis of skeletal muscle response to selection for rapid growth in japanese quail (coturnix coturnix japonica). | a line of japanese quail selected for high body weight at 4 weeks of age (p line) was compared to an unselected control (c) line at 10, 23 and 56 days of age. the increase in the weight of the pectoralis major and supracoracoideus muscles in the p line was paralleled by an increase in total dna, rna and protein content of the muscles when compared to comparable age c line. dna, rna and protein concentrations and rna/dna and protein/dna ratios were similar between lines within age. greater muscle ... | 1980 | 6159255 |

| [the effect of electroconvulsive shock on protein synthesis in japanese quail]. | trials were conducted to study the effect of electroconvulsive shock in the susceptible period of post-natal development upon the proteosynthesis of the japanese quail. proteosynthesis was determined by the incorporation of labelled amino acid and nucleoside in the proteins and dna of liver and oviduct. the tested birds showed an earlier sexual maturity, higher incorporation of labelled amino acid in protein and labelled nucleoside in dna in liver and oviduct, and a higher egg yield at a lower f ... | 1981 | 6171086 |
| continuous ingestion of different chlordecone (kepone) concentrations and changes in quail reproduction. | to determine the effects of continuous ingestion of different chlordecone concentrations on quail reproduction and mortality, 5-wk-old female japanese quail were fed a diet containing 10, 40, 80, and 160 ppm chlordecone for exactly 250 d. continuous ingestion of 10-80 ppm chlordecone did not induce excessive mortality or significantly alter reproductive functions. similar ingestion of 160 ppm chlordecone increased quail mortality, produced a log in egg production, and affected the normal sequenc ... | 1981 | 6175762 |
| composition and muscle cellularity of japanese quail after selection for high body weight under an optimal or suboptimal nutritional environment. | the purpose of this study was to determine if the compositional and cellularity changes associated with selection for rapid growth rate in an optimal and suboptimal nutritional environment were similar. the p-line japanese quail had undergone long-term selection for high 4-week body weight and received a 28% protein diet. the unselected c-line quail received the same diet. t-line quail were selected by the same criteria as p-line quail but received a 20% protein diet containing .2% thiouracil. b ... | 1982 | 6178101 |
| characterization of a genetically segregating determinant of chicken fetal antigen by a new hapten inhibition of microcytotoxicity (him) assay. | the immunodominant structure of a chicken fetal antigen (cfa) determinant was investigated using a new hapten inhibition of microcytotoxicity (him) assay. this him assay employing avian erythrocytes was shown to be a highly sensitive, economical technique and was verified in a separate experiment using bovine serum albumin (bsa) coupled to japanese quail peripheral red blood cells (qprbcs). inhibition of microcytotoxicity was measured following preincubation of 1 microliter of specific antiserum ... | 1982 | 6180728 |
| japanese quail embryo cell line persistently infected with erythroblastosis virus. | a japanese quail embryo cell line transformed by avian retrovirus, designated qerc-31f, was further characterized in virological and cytological aspects. infectious virus produced by this cell line was found to belong to subgroup a. the virus failed to transform quail embryo cells, whereas it induced erythroblastosis by injection into neonatal quails. injection of qerc-31f cells into neonatal quails resulted in the induction of solid tumors which morphologically diagnosed as undifferentiated sar ... | 1982 | 6181272 |
| suppression of natural killer cell activity by chicken alpha-fetoprotein in japanese quails. | spleen cells taken from quails treated with chicken alpha-fetoprotein (ch-afp) showed reduced natural killer (nk) activity as did spleen cells taken from quails treated with chicken amniotic fluid (chamf) in which the presence of ch-afp was demonstrated by a gel precipitation test. the ch-afp-induced reduction of nk activity was shown to be mediated by suppressor cells. in addition, ch-afp-treated quails developed tumors with shorter latent periods than those of the tumors that developed in untr ... | 1983 | 6187964 |
| avian lh and fsh: comparison of several radioimmunoassays. | comparisons were made between various lh and fsh radioimmunoassays currently being used to measure avian hormones. the two lh assays were the homologous chicken system of follett et al. (1972) and the turkey assay of burke et al. (1979). these assays were also used in heterologous arrangement by interchanging the iodinated lh fractions and antisera. five fsh assays were analyzed: two homologous chicken systems (scanes et al., 1977; sakai and ishii, 1980). an assay based on mammalian materials (r ... | 1983 | 6189763 |
| surface marker for hemopoietic and endothelial cell lineages in quail that is defined by a monoclonal antibody. | a mouse monoclonal antibody raised in response to quail immunoglobulin mu chain was found to exhibit a broad reactivity towards hemopoietic and endothelial cells in the quail (coturnix coturnix japonica). indirect immunofluorescence assays were performed at several stages of embryonic development and until 3 weeks after hatching, on either isolated cells or tissue sections. they revealed that the defined surface marker, referred to as mb1, (i) is expressed early on both intra- and extraembryonic ... | 1983 | 6190166 |
| the role of serum binding proteins in determining free thyroid hormone concentrations during development in quail. | japanese quail were used as a model for studying the role of binding proteins in determining free t4 (ft4) and free t3 (ft3) concentrations during development. adults were used to characterize thyroid hormone binding; developmental stages studied were late embryonic, perinatal, hatchling, and juvenile. total and free hormones were determined directly by ria, and free hormones were determined indirectly by equilibrium dialysis. binding proteins were identified by electrophoresis of serum preincub ... | 1983 | 6191971 |
| demonstration of free reverse transcriptase in the nuclei of embryonic tissues of the japanese quail. | reverse transcriptase is detected in the nuclei as well as the cytoplasm of normal uninfected japanese quail embryonic tissues. at least 60% of the nuclear enzyme occurs in the free-form, whereas 85% of the cytoplasmic enzyme is bound to particles having a buoyant density equivalent to retroviral cores (1.19-1.22 g/ml). the enzyme is purified by ion-exchange chromatography and glycerol sedimentation gradients. it prefers oligo(dg) . poly(c) in mg2+ to all other synthetic template-primers, and tr ... | 1983 | 6196028 |
| [experimental study on the etiology of idiopathic scoliosis--a deviation of lower motor neurons of the spinal muscle detected by the horseradish peroxidase method]. | in order to elucidate the etiology of idiopathic scoliosis, studies were carried out by hrp method on the topographical localization and numerical alteration of spinal motor neurons innervating the spinal muscle of the non-scoliotic japanese quail and the scoliotic one established by s. hijikata in 1976. the topographical localization of spinal motor neurons innervating the triceps brachii muscle of the both groups, furthermore, was examined by the same method, and the anatomical fiber connectio ... | 1983 | 6197498 |
| [use of deae-sephadex a-50 microcarriers for reproduction of the mumps virus]. | reproduction of the vaccine l-3 strains of mumps virus was studied in cultures of continuous vero cells and in primary cultures of japanese quail embryos (jqe) growing on deae-sephadex a-50 microcarriers. the vero cell culture multiplies actively on the microcarrier surface giving more than a 20-fold increase in 8 days. mumps virus showed a high reproductive capacity in vero cell culture and in primary jqe cells. mumps virus-infected vero cells produce 5-6 pools of virus-containing material with ... | 1984 | 6201007 |
| effects of low levels of dietary lead and iron on hepatic rna, protein, and minerals in young japanese quail. | day-old japanese quail were fed purified diets containing either 0.2 (control), 5.4, or 16.2 ppm lead as the acetate with either 25 (deficient) or 100 ppm (adequate control) iron for 2 weeks. iron deficiency caused decreases in hemoglobin, iron, and manganese in the liver, and hepatic rna synthesis. iron deficiency also caused increased concentrations of lead, calcium, and molybdenum in the liver. lead supplements caused increased concentrations of lead in the liver, and with adequate dietary ir ... | 1984 | 6201350 |
| the developmental distribution of monoamines in the brain of male japanese quail (coturnix coturnix japonica). | changes in the levels of the brain catecholamines, norepinephrine (ne) and dopamine (da), were studied in the male japanese quail during maturation. in addition the neurotransmitter, serotonin (5ht), its precursor, tryptophan ( tryp ), and its metabolite, 5-hydroxyindoleacetic acid (5hiaa), were measured. birds were sampled at weekly intervals between the ages of 1 and 63 days of age. brains of the quail were dissected into cerebral hemispheres, diencephalon, brain stem, cerebellum, and optic lo ... | 1984 | 6203106 |
| a golgi study on the neuronal morphology in the hypothalamus of the japanese quail (coturnix coturnix japonica). i. tuberal and mammillary regions. | neuronal morphology and dendritic architecture of the tuberal and mammillary regions in the hypothalamus of the quail (coturnix coturnix japonica) were investigated by means of classical neuroanatomical methods (bodian silver impregnation, luxol-fast blue, cresyl violet, toluidine blue, rapid golgi method). the tuberal region is characterized by isodendritic neurons, in particular: a) pyriform and bipolar neurons, occasionally arranged diagonally to the ventricular surface; b) csf-contacting neu ... | 1984 | 6203645 |
| avian peritoneal exudate cells: a comparison of stimulation protocols. | the influence of different stimulation protocols on the induction of peritoneal exudate cells (pecs) and adherent cells, and on the percentage of different adherent cell types was examined in the chicken and japanese quail. the results suggest that different protocols may be selected to maximize isolation of specific pec populations for immunological studies. in the chicken, starch, peptone, glycogen, and sephadex g-40 were all equally effective and superior to saline in generating pecs. while a ... | 1984 | 6203782 |
| chlordecone (kepone) induced ultrastructural and morphometric alterations in the cells of the immature quail oviduct. | groups of sexually immature japanese quail females, kept in a reduced photoperiod, received either daily intraperitoneal injections of 40 micrograms estradiol-17 beta for 26 days or were fed diets containing 0, 10, 40, 80 or 160 ppm chlordecone for the same duration. estradiol-17 beta induced rapid cellular hypertrophy, cytodifferentiation, tubular gland formation, organelle proliferation and secretory granule formation in different cells of the quail oviduct. higher chlordecone doses mimicked t ... | 1984 | 6208637 |
| changes in the nucleic acid and protein content of the japanese quail during postnatal development. | a study of growth activity in the japanese quail showed the rate of growth to be the highest, in both sexes, between the ages of 5 and 20 days. positive allometry was manifested in skeletal muscle development, negative allometry or isometry in the case of the liver and heart. the protein/p dna ratio rose progressively with age in all the given tissues and attained the maximum prior to sexual maturation. the p rna/p dna ratio rose markedly in all the tissues after only a few days and remained hig ... | 1984 | 6209738 |
| isolation of ureaplasmas from poultry and experimental infection in chickens. | ureaplasmas were isolated from the oropharynxes of 47 of 247 (19 per cent) leghorn chickens (gallus gallus domesticus) and from five japanese bantams but none was isolated from the oropharynx or cloaca of other poultry comprising 10 japanese game, 75 common quails (coturnix coturnix japonica), 17 turkeys (meleagris gallopavo) and 10 guinea fowls (numida galeata). in apparently healthy chickens, ureaplasmas were found at various sites, including the conjunctiva, nasal cavity, oropharynx, upper an ... | 1982 | 6211817 |
| keratan sulfate proteoglycan isolated from the estrogen-induced medullary bone in japanese quail. | 1. two proteoglycans isolated from the femurs of quail actively producing medullary bone were separated using deae bio-gel a. 2. the first to elute in the gradient was a keratan sulfate proteoglycan with an average buoyant density of 1.53 g/ml and a kav = 0.57 on sepharose cl-4b. 3. the second proteoglycan to elute contained chondroitin 4-sulfate. 4. apparently only the keratan sulfate proteoglycan is associated with the new medullary bone matrix. | 1982 | 6214368 |
| the effect of mercury and vitamin e on tissue glutathione peroxidase activity and thiobarbituric acid values. | the effects of methyl mercuric chloride (ch3 hgcl) and mercuric chloride (hgcl2) on red blood cell (rbc), plasma, and liver glutathione peroxidase (gsh-px) activities were determined in japanese quail fed a semipurified diet with 1 ppm added selenium (se). the rbc gsh-px activity was significantly increased by 5 ppm mercury (hg) as ch3 hgcl. plasma gsh-px activity was significantly depressed only in th 20 ppm hg group. liver gsh-px activity was not affected. the rbc gsh-px activity was significa ... | 1982 | 6215642 |
| [toxicity and certain physiopathologic effects of 2,4,5-trichlorophenoxyacetic acid, an organo-chlorine herbicide, in the adult domestic quail (coturnix coturnix japonica)]. | the effects of 2,4,5-t on adult japanese quail have been studied. the herbicide was administered daily in oral dosages at level of 100 mg/kg per day for two weeks (five days a week). in these experimental conditions, this compound was moderately toxic, the rate of mortality was low. however, we noticed a significant reduction in food consumption, body weight and egg production. the physiological disturbances resulting from the toxicological treatment are reversible. | 1982 | 6217874 |
| induction of vitellogenesis in japanese quail as a sensitive indicator of the estrogen-mimetic effect of a variety of environmental contaminants. | vitellogenesis was induced in mature male japanese quail following intramuscular injections of 16 mumol/100 g body weight of any one of four estrogen analogues or 160 mumol/100 g of the nonsteroid zearalenone. six hours after the injections, microgram levels of vitellogenin were detected and quantitated by rocket immunoelectrophoresis. sodium dodecyl sulfate polyacrylamide gel electrophoresis of plasma from estrogen-treated birds and from 160 mumol zearalenone-treated birds showed, 4 days after ... | 1984 | 6237320 |
| androgen regulation of secretions in the sebaceous-like uropygial gland of the male japanese quail. | the uropygial gland of the male quail is a sebaceous-like, androgen-dependent structure. the waxes secreted by this gland consist of fatty acids esterified by alkane-2,3-diols. in adult male quail the relative concentrations of all fatty acids were not affected by castration and testosterone treatment; but in contrast, the relative concentration of dodecane diol was found to be correlated with the androgen levels. in castrated quail administration of testosterone induced an increase in the dodec ... | 1984 | 6238117 |
