Effect of maltose infusion on amino acid composition of maternal venous blood and fetal blood in utero

Effect of maltose infusion on amino acid composition of maternal venous blood and fetal blood in utero. Nishijima, Mitsushige; Iwata, Mitsuru (Sch. Med., Iwate Medical Univ., Morioka, Japan). Nippon Sanka Fujinka Gakkai Zasshi, 35(12), 2339-48 (Japanese) 1983. 69-79-4 is the cas registry number. This chemical is also mentioned in this article. CODEN: NISFAY. ISSN: 0300-9165. DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) Maltose [69-79-4] was given i.v. to women during labor and the compn. of maternal venous blood (MV), umbilical venous blood (UV), and umbilical arterial blood (UA) was monitored, and the results compared to values obtained with a noninfused group of women. Blood glucose was higher in MV and UV in the infusion group. Maltose showed a significant correlation only between UV and UA. Glucose and maltose had no significant correlation. Valine, tyrosine, and ethanolamine were significantly lower in MV with infusion. Aspartic acid in UA was significantly lower with infusion. Phenylalanine in UV and UA were significantly higher with infusion. Phenylalanine in UV showed a significant correlation with the maltose level. Activities of glutamine dehydrogenase, isocitrate dehydrogenase, g-glutamyl transpeptidase, and blood urea N did not change following maltose infusion. These results suggest that clin. efficiency of maltose infusion in promoting fetal growth can be caused not only on the increased supply of glucose but also the efficient use of transported amino acid in the fetus. .

Effects of D-valine on pulmonary artery endothelial cell morphology and function in cell culture

Effects of D-valine on pulmonary artery endothelial cell morphology and function in cell culture. Picciano, P. T.; Johnson, B.; Walenga, R. W.; Donovan, M.; Borman, B. J.; Douglas, W. H. J.; Kreutzer, D. L. (Dep. Pathol., Univ. Connecticut Health Cent., Farmington, CT 06032, USA). Exp. Cell Res., 151(1), 134-47 (English) 1984. CODEN: ECREAL. ISSN: 0014-4827. DOCUMENT TYPE: Journal CA Section: 13 (Mammalian Biochemistry) The effects of D-valine on the cell culture of bovine pulmonary artery endothelial cells were studied using D-valine-modified Minimal Essential Medium (MEM). D-Valine-treated cultures (46-920 mg/L) were compared with replicate cells grown in L-valine (46 mg/L)-MEM. All media were supplemented with 15% fetal bovine serum. Endothelial cells were grown for 14 passages with split ratios varying from 1:3 to 1:6. 58-82-2 and 363-24-6 which are cas registry numbers of substances are two of reagents here. Unlike cells grown in L-valine MEM, cells grown in D-valine MEM did not become contaminated by the growth of fibroblasts in primary cultures. D-Valine-treated cells grew in cobblestone array, exhibited contact inhibition, and strongly expressed factor VIII antigen. D-Valine-grown cells produced PGI2 in greater proportion to PGE2, both constitutively and when stimulated by bradykinin, in comparison with cells grown in L-valine. In addn., cells grown in L-valine, although able to express factor VIII, were not comparable to D-valine cells with respect to other parameters assayed (morphol. and growth as a monolayer). .
