Carbon Dioxide Fixation In Schistosoma Mansoni, Clint Earl Carter
Loma Linda University Electronic Theses, Dissertations & Projects
Adults of the blood fluke Schistosoma mansoni were perfused from the hepatic portal system of CF1 female mice sixty to seventy days post infection. The worms were then incubated in Eagle’s minimal essential medium with glutamate and 0.03 mg/100 ml of nonlabelled aspartic acid. To this medium was added 10 μc of either NaH1403, glucose-UC14 or aspartate-4-C14. The worms were found to fix carbon from the NaH1403 and to incorporate the glucose and aspartate. The amount of activity recovered in five different chemical fractions after two hours incubation was determined …
The Effect Of Schistosoma Mansoni On Free Amino Acid Levels In Mice, Richard D. Tkachuck
The Effect Of Schistosoma Mansoni On Free Amino Acid Levels In Mice, Richard D. Tkachuck
Loma Linda University Electronic Theses, Dissertations & Projects
Free amino acid levels in the blood plasma of mice infected with Schistosoma mansoni Sambon, 1907, were measured at 3, 6, and 9 weeks post-infection with an automatic amino acid analyzer. Significant differences between experimental and control animals occurred at all three time periods. At 3 weeks, asparagine, alanine, citrulline, proline, methionine, and threonine levels all were lower in the infected animals. At 6 weeks, four differences were noted. Alpha-amino-n-butyric acid, ornithine, lysine, and histidine all had lower values in infected animals. At 9 weeks there were 12 differences. Tyrosine, phenylalanine, threonine, serine, proline, citrulline, glycine, alanine, valine, isoleucine, and …
