High Temperature and Humidity Effect on Biochemical Characteristics of Organically-Grown Parsnip Roots Compared to Garlic Bulbs.

Functional food with high concentrations of monosaccharides and antioxidants is important for quick replenishment of energy reserves and rehabilitation after intensive oxidant stress. The effect of high temperature and humidity for manufacturing such products from parsnip roots of three cultivars (Zemchug, Krugly, Bely aist) compared to garlic bulbs from cultivar Demidovsky was investigated. The processed parsnip demonstrated higher antioxidant activity than 'black garlic': phenolics (22.

Production of nitrogen oxide derivatives under the influence of NO-synthase inhibitors and natural compounds in mice with transplanted tumors.

Aim: The aim of the present study was to investigate the dynamics of nitric oxide derivative (NOD) formation in mice with transplanted tumors and to analize whether synthetic NO-synthase inhibitors, NO-donors and natural compounds could modulate NOD synthesis.

Materials And Methods: In the study F(1)(C(57)BlxCBA), CBA/Lac, BDF and Balb/c mice were used. Endogenous NOD synthesis in mice with transplanted Ehrlich carcinoma (EC) and Lewis lung carcinoma (LLC) was estimated by measuring urine nitrates (NA) and nitrites (NI) excretion and their concentration in tumor tissue determined by cadmium-reduction method.

Antioxidant status of rats receiving lycopene in different doses.

Oral treatment with lycopene (per os) in doses of 10 or 50 mg/kg for 2 weeks led to accumulation of lycopene in the liver, liver microsomes, and blood plasma, increased total plasma antioxidant activity, inhibited LPO in the liver, and decreased solubilization of lysosomal enzymes. Lycopene had no effect on ex vivo resistance of liver microsomes to LPO and activities of antioxidant enzymes in the liver.

[Inhibiton of endogenous synthesis of nitroso compounds by Selenium in rats].

The inhibiting effect of organic Se (selen-enriched yeast Bioselen) on the endogenous synthesis of N-nitrosubstances was investigated in the Wistar rats, receiving 15 mg of sodium nitritis and 24 mg of diethylamin per 1 kg of bodyweight during 22 days. The level of nitrosoprolin synthesis and (NPro) and the level of nitrosodiethyl (NDie) in the stomach of rats served as the main indices. The highest level of NPro and NDie were revealed in the rats, without selen supplementation (581.
