The activity of endothelial and inducible NO-synthases and the content of S-nitrosothiols were studied in the small intestine homogenates of rats with chronic experimental gastroenterocolitis caused by food additive carrageenan intake during 2 and 4 weeks. It was established that carrageenan intake during 2 weeks led to a decrease of eNOS activity and increased the activity of iNOS in small intestine homogenate, causing increased production of NO and, therefore of Snitrosothiols. A decreased NO synthesis in four-week use of carrageenan indicated a potential role of NO deficiency in the development of microcirculatory disorders and chronic inflammation.
