We have shown recently that in the dog progestin administration results in mammary production of immunoreactive growth hormone (GH). At present we demonstrate the expression of the gene encoding GH in the mammary gland of dogs and cats using reverse-transcriptase PCR. GH mRNA was found in the great majority of normal mammary tissues as well as benign and(More)
The use of the synthetic progestin medroxyprogesterone acetate (MPA) for estrus prevention in the dog can result in overproduction of growth hormone, suppression of plasma glucocorticoid levels, and the induction of mammary tumors. Proligestone (PROL) was claimed to be devoid of these unwanted side effects. In the present study, the binding characteristics(More)
Corticotropin-releasing hormone (CRH) and vasopressin are the most important hypothalamic factors regulating adrenocorticotropic hormone (ACTH) secretion. In this study we have investigated the responsiveness of the pituitary-adrenocortical axis to intravenous administration of CRH or lysine vasopressin (LVP) in 16 control dogs, 22 dogs with(More)
We have estimated the incidence of microand mini-satellites in the dog genome. A genomic phage library from canine liver, with an average insert size of 16 kb, was screened to detect potentially polymorphic microand mini-satellite sequences, which may be useful for the development of markers of inherited diseases, for fingerprinting, or for population(More)
Pituitary surgery generates pituitary tissue for histology, immunohistochemistry, and molecular biological research. In the last decade, the pathogenesis of pituitary adenomas has been extensively studied in humans, and to a lesser degree in dogs, and tumor oncogenesis has been studied in knock-out mice, often by means of quantitative reversed-transcriptase(More)
BACKGROUND Intervertebral disc (IVD) disease is a common spinal disorder in dogs and degeneration and inflammation are significant components of the pathological cascade. Only limited studies have studied the cytokine and chemokine profiles in IVD degeneration in dogs, and mainly focused on gene expression. A better understanding is needed in order to(More)
Measurement of plasma osmolality (Posm) and plasma vasopressin (VP) concentration in response to hypertonicity is regarded as the gold standard for the assessment of VP release in polyuric conditions. Yet the interpretation of the VP curve as a function of Posm may be hampered by the occurrence of VP pulses. To determine whether VP is secreted in a(More)
INTRODUCTION Strategies for biological repair and regeneration of the intervertebral disc (IVD) by cell and tissue engineering are promising, but few have made it into a clinical setting. Recombinant human bone morphogenetic protein 7 (rhBMP-7) has been shown to stimulate matrix production by IVD cells in vitro and in vivo in animal models of induced IVD(More)
Calcitonin (CT) is a major calcitropic hormone. Because of low cross reactivity of canine CT (cCT) in radioimmunoassays (RIA) developed for other species, a homologous RIA is needed. Synthesis of cCT allowed study of its biologic potency using a rat bioassay and its plasma half-life in dogs. The availability of cCT also made possible the development of a(More)
Tissue enzyme profiles of heart, liver, pectoral muscle, quadriceps muscle, duodenum, kidney and brain from racing pigeons were established. The enzymes were alanine aminotransferase (ALAT), aspartate aminotransferase (ASAT), glutamate dehydrogenase (GLDH), lactate dehydrogenase (LDH), gamma glutamyltransferase (y-GT), alkaline phosphatase (AP), and(More)
