Age differences in the associations between felt temperatures and color choices.

Thirty-six subjects, twelve each at 6, 12, and 18 years of age, were asked which of four colors (blue, green, yellow, or red) they were reminded of by each of four temperatures (containers at 4, 23, 35, or 45 deg C). More 18-year-olds than expected by chance made each of the conventional associations: hot/red, warm/yellow, cool/green, cold/blue. The 12-year-olds reliably made the hot/red association but none of the others. No more 6-year-olds than expected by chance made any of the conventional associations. The results suggest that the conventional associations are founded on a loosely held cultural norm rather than on an evolutionary or physiological basis.

Endogenous steroid concentrations in human breast tumours determined by high-resolution mass fragmentography.

A pilot study of the endogenous steroid concentrations in human breast tumours was performed. The technique of high-resolution molecular-ion monitoring during combined g.l.c.-mass spectrometry was used to determine oestrone, oestradiol-17beta and oestriol in concentrations above 1ng/g wet wt. of tissue, and dehydroepiandrosterone, testosterone, androsterone (3alpha-hydroxy-5alpha-androstan-17-one) and 3beta-hydroxy-5alpha-androstan-17-one in concentrations exceeding 5ng/g, in extracts of five primary breast tumours.

Gastric emptying of solid meals after truncal vagotomy and pyloroplasty in human subjects.

Gastric emptying of isotopically labelled solid meals was studied in normal human subjects and in patients at different intervals after truncal vagotomy and Heineke-Mikulicz pyloroplasty. One to four weeks after vagotomy and pyloroplasty gastric emptying was delayed grossly in some patients regardless of the completeness of vagotomy. Patients with gross delay had symptoms of gastric retention. Eight weeks later emptying had returned towards normal and one or more years after vagotomy and pyloroplasty emptying was within the normal range.A subthreshold dose of carbachol injected during the course of emptying of a meal in some of the postvagotomy patients had no detectable influence on the rate of emptying of the meal.
