Effects of Calcium Regulating Hormones on Osteoclast-Like Cell Formation in Hen Medullary Bone Marrow Culture
hen medullary bone osteoclast differentiation calcium regulating hormone
2009/7/31
In order to examine the effects of the calcium regulating hormones on the differentiation of hen medullary bone osteoclasts, isolated medullary bone marrow cells were cultured for 8 days in media incl...
Accumulation of ZP1 and ZPC in Quail Perivitelline Membrane During Follicular Development
extracellular matrix Japanese quail perivitelline membrane ZP1 ZPC
2009/7/31
The extracellular matrix surrounding the oocyte before ovulation is called perivitelline membrane (PL) in avian species. We previously reported that one of its components, ZPC, is produced in the ovar...
Comparison of Hypothalamic Monoamine Contents of Broiler- and Layer- Type Chickens at Prehatch and Posthatch
monoamines monoamine metabolites hypothalamus broiler-type chicken layer-type chicken
2009/7/31
Domestic chickens, which are precocial, have relatively well developed mechanisms of food intake regulation at hatch. Although their body weight is similar at hatch, broiler- and layer-type chickens ...
Changes in the Localization of MHC Class II Positive Cells in Response to Salmonella enteritidis Invasion in the Ovary of Laying Hens
follicles ovary MHC-II+ cells Salmonella enteritidis
2009/7/31
Major histocompatibility complex class II (MHC-II) molecules play essential roles in the initiation of immune responses against pathogenic agents. Salmonella enteritidis (S. enteritidis) bacteria may ...
A Study on the Back Flow of Urine into the Ceca of Chickens
adult chicken ceca cecostomy urine back-flow
2009/7/31
A cecostomy technique was developed to quantify urine back flow into the ceca of fed and feed-deprived adult male chickens.
On the two days after surgery, the tubings of cecostomized chickens were fl...
Effects of Estrogen Treatment During the Embryogenic Period on Chick Antibody Production
estrogen chick embryo antibody production bursa of Fabricius helper T cells
2009/7/31
Antibody production against a T cell-dependent antigen (goat red blood cell) and a T cell-independent antigen (killed Brucella abortus) was examined in chicks treated with estrogen in which eggs were ...

2009/7/31
Antibody production against a T cell-dependent antigen (goat red blood cell) and a T cell-independent antigen (killed Brucella abortus) was examined in chicks treated with estrogen in which eggs were ...
Comparative Effects of Intravenously Single-injected D-[U-13C]Glucose and [1-13C]Sodium Acetate on Time Course Changes in 13C Enrichment of Respiratory CO2 in Growing Chickens
growing chicken glucose oxidation acetate oxidation respiratory 13CO2
2009/7/31
This study was carried out to examine which of intravenous glucose or acetate would be rapidly oxidized to CO2 in growing chickens fed a semi-purified diet.
Estrogen Receptor Binding of Xenoestrogens and Phytoestrogens in Japanese Quail (Coturnix japonica)
estrogen receptor endocrine-disrupting chemicals phytoestrogens Japanese quail recombinant ERα
2009/7/31
Estrogenic compounds must bind to estrogen receptors (ER) and modulate estrogen-sensitive gene expression. However, various in vivo and in vitro assays have established that xenoestrogens and phytoest...
Changes in Localization of T Cell Subsets in the Ovarian Follicles during Follicular Growth and Ovulation in Hens
follicular growth laying hens ovarian follicles T cell subsets
2009/7/31
Changes in the localization of helper and killer T cells (CD4+ and CD8+ T cells, respectively) in hen ovarian follicles with follicular growth and ovulation were examined in this experiment. White fol...
Effects of Age and Gonadal Steroids on the Localization of T Cell Subsets in the Epididymis of Male Chickens, Gallus domesticus
