Abstract:
Saffron is used in traditional medicine for its hypolipidemic, anti-inflammatory and anti-carcinogenic properties as a natural remedy in treatment of diseases. The objective of the present study was to demonstrate the protective effect of crocin (one of the main ingredients of saffron) on carbon tetrachloride (CCl4) damage in intestinal mucosa. MDA, GSH, SOD, CAT, TAS and TOS levels were measured in experimental animal tissue samples and these were compared with histologic lesions induced by CCl4. CCl4 caused an increase in MDA, SOD, CAT and TOS levels and a significant decrease in GSH and TAS levels in rat intestinal tracts. After crocin treatment, serious improvements were observed in histological lesions and biochemical results in the intestinal tract. In conclusion, crocin inhibited the toxic effects induced by CCl4 in the intestine by its strong antioxidant properties.

Phase I Reactions: Oxidation of Carbon-Heteroatom and Miscellaneous Systems
In carbon-nitrogen systems, aliphatic and aromatic amines can undergo oxidative reactions. Secondary and tertiary amines, like those found in tricyclic antidepressants, can undergo N-dealkylation, a process that involves the oxidation of the alkyl group. In addition, oxidative...

Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...
