The HD11 chicken macrophage cell line was studied for growth characteristics using different culture media, serum concentrations, and incubation temperatures. Growth curves at 37 C revealed that the cells grew best in RPMI 1640 medium supplemented with 10% colostrum-free bovine serum (CFBS). Growth was not supported by RPMI 1640 medium supplemented with the(More)

PREFACE The main objective of this publication is to recommend common names for the indicator plants used in Ecology Programme publications. For some species, there are many common names — for others, there may be only one or even none in " common " usage. For species with many vernacular names, the choice of any one name is often arbitrary, however, I(More)
High-affinity binding of [3H]acetylcholine to muscarinic cholinergic sites in rat CNS and peripheral tissues was measured in the presence of cytisin, which occupies nicotinic cholinergic receptors. The muscarinic sites were characterized with regard to binding kinetics, pharmacology, anatomical distribution, and regulation by guanyl nucleotides. These(More)
The existence of typical muscarinic receptors in membranes of sheep anterior pituitary was detected by binding of [3H]quinuclidinyl benzilate ([3H]QNB), a potent and specific muscarinic antagonist. [3H]QNB binding sites in anterior pituitary had an equilibrium dissociation constant of about 20-40 pM, a rate constant for association at 37 degrees C of about(More)
A survey of the regional distribution of binding of 1 nM [3H](3-Me-His2)thyrotropin-releasing hormone ([3H]MeTRH) to TRH receptors in the brains of eight mammalian species revealed major species differences in both the absolute and relative values of TRH receptor binding in different brain regions. Several brain regions exhibited binding equal to or(More)
The role of calcium in transducing the signal for interleukin-1 (IL-1) secretion was examined in the MQ-NCSU chicken macrophage cell line. Cells were maintained in RPMI 1640 medium supplemented with 5% chicken serum and antibiotic-antimycotic solution at 40 C and 5% CO2. The effects of stimulation with lipopolysaccharide (LPS), calcium ionophore A23187, or(More)
There has been extensive interest in the role of serotonin (5-hydoxytryptamine, 5-HT) in the pathogenesis of pulmonary hypertension because episodes of pulmonary arterial hypertension in humans have been linked to serotoninergic appetite-suppressant drugs. In this study, we investigated the role of serotonin in the development of pulmonary hypertension(More)
TRH binds to sites in the nucleus accumbens-septal area of sheep brain. These sites appear to represent receptors for at least some of its behavioral effects in other species and are very similar to sheep pituitary receptors. All measurements were performed on ice to prevent peptide degradation. High affinity [3H]TRH binding in brain regions was(More)
