The Effects of Ascorbic Acid on in vitro Heterophil Function

As a feed additive, ascorbic acid has been shown to have a protective effect against bacterial and viral diseases and to reduce the impact of detrimental stress in chickens. This study examined the effect of ascorbic acid treatment on in vitro heterophil function by examining random migration and phagocytosis and bacterial killing of Staphylococcus aureus. Heterophils were evaluated in broiler chickens ranging from 5 to 16 wk of age, and age differences were seen. Significant increases in bacterial killing were found in heterophils treated with ascorbic acid, and this difference tended to be greater in chickens from 5 to 10.5 wk of age. No significant differences were found in phagocytosis or random migration, but ascorbic acid tended to decrease random migration. The most significant effect on in vitro heterophil function was an increase in bacterial killing.

Ascorbic Acid Effect on Pericycle Cell Line inAllium CepaRoot

SUMMARYThe pericycle cells in Allium cepa root tip undergo differentiation at 2C level. The present study indicates two clear effects of ascorbic acid treatment on pericycle cell line: i) the extension of the upper limit of mitosis from the tip; ii) the increase of the labelling index. In a previous paper we have just found that, in Allium cepa, treatment with ascorbic acid stimulates the G1 nuclei of the quiescent centre to undergo DNA synthesis. Our present results suggest the hypothesis that ascorbic acid could have a regulatory role of cell proliferation during the G1 phase.
