Trypsin inhibitor and maternal reunion increase plasma cholecystokinin in neonatal rats.

Intragastric soybean trypsin inhibitor increased plasma CCK bioactivity by 87% in nondeprived, 9-12-day-old rat pups. Reunion with the dam for 1 h after overnight maternal deprivation also increased plasma CCK significantly. These results demonstrate that CCK can be released from the small intestine of rats as early as postnatal day 9.

Animals

Variation of the amide I and amide II peak absorbance ratio in human hair as measured by Fourier transform infrared spectroscopy.

Human scalp hair samples were examined by Fourier transform infrared spectroscopy and the ratio of the amide I to amide II band absorbances was determined. The effects of hair oxidation, color, age of sample, and sex of source were examined. Scalp hair from 98 individuals was also analyzed. While there were differences in the amide absorption band ratios, these were difficult to relate to the individualization of the hair samples and did not appear to have a sufficient discriminatory value for routine forensic use.
