Vitamin U 生物活性

描述 DL-methionine methylsulfonium chloride is a naturally occurring methionine derivative. DL-methionine methylsulfonium chloride protects gastric mucosal from ethanol-induced damage. One milliliter of 1, 2, or 5% DL-cysteine (cysteine) or DL-methionine methylsulfonium chloride (MMSC) was instilled into the rat stomach 1, 24, and 48 h after giving ethanol (1 mL of 40% solution) by gavage. One hour following the administration of ethanol, gastric mucosal injury was seen in all the animals. Treatment with 2% cysteine or MMSC significantly (p less than 0.01) reduced the extent of this injury[1]. Gavage with 1% DL-cysteine or DL-methionine-S-methylsulfonium chloride at 1 mL/day for 2 weeks and 5 days protected against ulceration in 30% of the rats, and this protection extended to 80% of cases with 2% solutions. Similar gavage with 5% solutions protected all rats against ulceration without significantly influencing the basal H+ output [13.1 +/- 0.3 and 14.2 +/- 0.2 mumol for DL-cysteine and DL-methionine-S-methylsulfonium chloride, respectively, versus 15.1 +/- 0.4 mumol (mean +/- standard error of the mean; n = 10)]; that is, cytoprotection was achieved[2].
