In Vitro Vitamin C (L-ascorbic acid), a known enhancer of collagen deposition, has also been identified as an inhibitor of elastogenesis[1]. The conditioned medium for B16F10 cells significantly inhibits cell apoptosis induced by sodium L-ascorbate (10 mM), and the effective ingredients in the medium show a relative molecular mass below 5,000[2].
In Vivo Tg rats treated with sodium L-ascorbate show a higher incidence of carcinoma (29.6%), compared to those without sodium L-ascorbate (15.4%). Independent of the sodium L-ascorbate treatment, transgenic rats exhibit various kinds of malignant tumors in various organs[3]. After 12 weeks of PEITC-treatment, both simple hyperplasia and papillary or nodular (PN) hyperplasia have developed in all animals, but the majority of these lesions have disappeared at week 48, irrespective of the sodium L-ascorbate-treatment. The same lesions after 24 weeks of PEITC-treatment have progressed to dysplasia and carcinoma, in a small number of cases by week 48, but enhancement by the sodium L-ascorbate-treatment is evident only with simple hyperplasias and PN hyperplasias in rats[4].
Animal Admin A total of 40 7-week-old male Tg rats are divided into 2 groups. Twenty-seven (group 1) and 13 (group 2) rats are given a powdered MF diet with or without 5% sodium L-ascorbate, respectively. Similarly, a total of 42 7-week-old male Non-tg rats are divided into 2 groups, and 30 (group 3) and 12 (group 4) animals are given a diet with or without 5% sodium L-ascorbate, respectively.
