Brain development in neonatal rats nursing asparagine-deprived dams.

A possible requirement for dietary asparagine during lactation was investigated by measuring any adverse effect of maternal asparagine deprivation on the body growth and brain development of nursing rat pups. Each dam was given 7 pups to nurse. Three groups of 5 dams each were deprived from the 1st (T1), 8th (T2), or 15th (T3) day of lactation until weaning (day 22); at weaning, the pups of each group weighed approximately 10% less than those of asparagine-fed controls.

Evidence for hydroxyacyl-ceramides and hydroxyacyl-cerebrosides in female rhesus monkey gingiva.

Materials believed to be hydroxyacyl-ceramides (HO-Cer) and hydroxyacyl-cerebrosides (HO-Ceb) have been analyzed by high performance liquid chromatography (HPLC) from the glycolipid components of six female rhesus monkey gingivae. These recovered materials show identical behavior by (HPLC) with authentic standards.

Gingival fluid fucose to protein ratios as indicators of the severity of periodontal disease.

Total fucose and protein was measured in gingival fluid samples collected from 16 human subjects. A significantly higher total protein concentration was found for the control (clinically normal) group when compared to the experimental (severe clinical inflammation) group. This is probably due to the higher gingival flow rate found in the experimental group.
