Five bactericidal peptides (chicken heterophil peptides CHP1 and CHP2; turkey heterophil peptides THP1, THP2, and THP3) were purified from avian heterophil granules. All peptides were cationic and rich in cysteine, arginine, and lysine. The complete amino acid sequence, consisting of 39 amino acids, was determined for CHP1. This peptide had a molecular(More)
Rats injected intraperitoneally with magnesium pemoline avoided a buzzing sound (conditioned stimulus) associated with an electric shock to the feet (unconditioned stimulus) more frequently than controls. Drug-injected rats did not avoid the foot shock more frequently than controls, although the experi mental rats did have shorter response latencies fn the(More)
After injection of leucine-H(3), members from eight triplets of rats were assigned to one of three treatment groups: avoidance learning, the same handling and shocks without opportunity to learn, or passive control. Autoradiographic grains over all nuclei were counted "blind." In the hippocampus, the number of grains for the learning rats was reliably(More)
Amino acid sequence analysis of a protein from chicken thymus tissue which promotes immunological maturity in chicken bone marrow cells in culture has established sequences of a 45-residue fragment, a 24-residue fragment and a 9-residue and an 8-residue peptide. Independent comparison of the 45- and 24-residue fragments with known amino acid sequences by(More)
Chicken leg muscle parvalbumin was digested with cyanogen bromide or trypsin or trypsin after citraconylation. Peptides isolated by reverse phase HPLC at pH 7.0 were subjected to acid hydrolysis and amino acid analysis and, in some cases, sequencing. The chicken muscle parvalbumin amino acid sequence has ca. 80% sequence identity with alpha-type(More)
