Effect of intraperitoneal administration of vitamin C (ascorbic acid) on anemia in experimental Trypanosoma congolense infected rabbits

The effect of Vitamin C supplementation on anemia in experimental Trypanosoma congolense infected rabbits was investigated. Locally bred rabbits were infected with 6 ´ 106 trypanosomes per rabbit and infection was monitored for 5 weeks. Packed cell volume (PCV), Total leucocytes count (TLC) and parasite load were determined weekly. Vitamin C supplementation did not significantly affect...

Miscibility studies of PVC/PMMA and PS/PMMA blends by dilute solution viscometry and FTIR

The effect of polymer-polymer interactions on the miscibility of PVC/PMMA and PS/PMMA blends were studied in a broad composition range using viscosity and FTIR techniques. From the viscometric data, the presence of attractive forces among different polymers was evaluated according to Sun et al. (1990), by the determination of α parameter. Based on sign convention involved in the criterion, PS/PMMA system was...
