Hb F Kingston (G gamma 55 (D6) Met leads to Arg)

A fetal haemoglobin variant was noted in a healthy Jamaican infant of mixed African/Chinese extration. A two-dimensional chromatogram of the soluble tryptic peptides (Tp) showed 2 'new' ones. One was composed of the last 4 residues of the usually insoluble Tpgamma41-59. To permit a tryptic split this required a change of residue gamma 55 Met to Lys or Arg. The other new Tp contained arginine and was in the position expected for a Ty gamma41-55 (55 Arg). As the material was limited it could not be analysed. When after more than 6 years no example of Hb F Kingston had become available it was decided to describe the variant on the basis of the present evidence. (AU)

Exocrine pancreatic response to the venom of the scorpion, Tityus trinitatis

This paper records for the first time the exocrine pancreatic response to scorpion venom, in this case that of Tityus trinitatia, a scorpion endemic in Trinidad. The crude venom injected intravenously into fasting anaethetised dogs induced a secretion of the exocrine pancreas. The secretion evoked was rich in enzyme (AU)
