In this study, we aimed to investigate the protective effect of Vitamin U (Vit U) on amiodarone (AMD)-induced hepatotoxicity. Male Sprague-Dawley rats were randomly divided into four groups. Group I was control animals receiving corn oil for 7 days, Group II consisted of animals receiving Vit U (50 mg/kg) for 7 days, Group III consisted of animals receiving AMD (100 mg/kg) for 7 days and Group IV consisted of animals given AMD and Vit U (in same dose and time). AMD and Vit U were administered to rats by gavage. On the 8th day, all the animals fasted overnight were sacrificed. Blood and liver tissue samples were taken from animals. Serum total cholesterol levels and liver gamma glutamyl transferase (transpeptidase) adenosine deaminase and tissue factor activities, liver glycoprotein component level such as fucose, hexose and hexosamine were determined. All the parameters were found to be increased in AMD group as compared to control group. Administration of Vit U reversed these effects in AMD group. According to these results, we can conclude that Vit U can prevent AMD-induced liver injury.

“…It is able to moderate the damaging effects of numerous stressors by enhancing the production of dimethyl sulphopropionate which acts as an osmo-and cryoprotectant [8,9], and by increasing the biosynthesis of polyamines, and by regulating ethylene production [10][11][12]. Previous research has provided a large volume of information on the favourable physiological effects of exogenous SMM, which include increases in membrane stability [13], increases in the activity of enzymes that eliminate reactive oxygen species [14] and in the quantity of polyamines, which play an important role in defence against stress [10][11][12]. It was observed in maize seedlings exposed to a short period of severe chilling stress (+5°C) that SMM, like chilling stress, stimulated the expression of genes coding for the enzymes that catalyse the polyamine biosynthesis pathway starting from arginine and that of the C-repeat binding transcription factor, CBF1, involved in the regulation of responses to chilling stress.…”

The promising role of exogenous S-methylmethionine in agriculture, in the case of maize cultivation

Ludmerszki et al.: The promising role of exogenous S-methylmethionine in agriculture, in the case of maize cultivation - Abstract. Abiotic and biotic stress conditions have negative effects on growth and yield of crop plants worldwide. The need to improve the nutritional value, stress and disease tolerance of cultivated plants is of great importance. The problem is usually solved by breeding or by the production of transgenic plants; however, the application of biologically active substances with favourable properties can be an alternative, cost-and time-effective possibility. S-methylmethionine (SMM) is an intermediate compound in the plant sulphur metabolism, being ubiquitous in the plant kingdom. SMM has important role in stress and disease tolerance of plants by taking part in plant sulphur metabolism. Previous investigations have shown that SMM has beneficial effects on the physiological status of plants and provides protection against various stress factors. The present review aims to sum up the main results concerning the beneficial effects of SMM treatment against Maize dwarf mosaic virus infection and cold stress in maize, and to reveal the possible applications of SMM in agricultural practice.
