Trace metals accumulation in the eco-system water - soil - vegetation (Agropyron cristatum) - common voles (Microtus arvalis) - parasites (Hymenolepis diminuta) in Radnevo region, Bulgaria.

Background: Coal and coal processing industries provoke trace metal pollution, which has a negative effect on the water - soil - vegetation - small mammals eco-system, constituting part of the food chain and exerting a serious impact on human health.

Objectives: Assessment of the environmental impact of Maritza iztok coal complex, situated east of Radnevo town, Bulgaria, by tracking the dynamics and accumulation of trace metals in the eco-system water - soil - vegetation - common voles - parasites.

Methods: Samples from surface waters, their nearby uncultivated soils, meadow uncultivated vegetation (Agropyron cristatum) and field common voles (Microtus arvalis) were collected.

Dynamics of trace metals in the system water - soil - plant - wild rats - tapeworms (Hymenolepis diminuta) in Maglizh area, Bulgaria.

Background: The impact of chemical elements on the biosphere is a function of their concentration and chemical form. Elucidation and prognosing of the latters in water basins and soil extracts is of particular significance for the assessment of their bioaccumulation in plants and animals.

Objectives: Trace metals dynamics in the system water - soil-plant-wild rats - Hymenolepis diminuta in two agro-industrial zones (East and West) around Maglizh city, Bulgaria were investigated through experimental studies and thermodynamic modelling of the chemical species.

Anthelmintic efficacy of seed methanolic extract against .

The current study was carried out to assess in vitro and in vivo effects of seed methanolic extract on to develop an alternative source of treatment. The in vitro ovicidal effect of seed extract on immature eggs has provided evidence of inhibitory activity on the vitality and hatchability of eggs. This inhibitory activity was concentration-dependent and also correlated strongly with the exposure time.

Evaluation of different antigens for diagnosis of sheep haemonchosis by ELISA and their cross reactivity with other helminthes.

() remains important nematode that infecting sheep all over the world. Truthful diagnosis of haemonchosis needs reliable Enzyme linked immune sorbent assay test as well as the immuno-reactive protein profile of different prepared antigens; larval (L), excretory secretory product (ESP) and adult somatic (AS). The current study fulfilled that L antigen is the talented antigen for such serological diagnosis.

Zinc Supplementation against Eimeria acervulina-Induced Oxidative Damage in Broiler Chickens.

This study was undertaken to determine the dietary supplements of Zn containing diet on the antioxidant status in chickens experimentally infected with Eimeria acervulina. The antioxidant status was monitored via determination of MDA concentrations and erythrocyte SOD and CAT activities, as well as vitamin E, vitamin C, Cu, and Zn in liver, muscle, and serum. The results showed increased MDA (P < .

Selenium supplementation at low doses contributes to the antioxidant status in Trichinella spiralis-infected rats.

Selenium (Se) supplementation may prevent the formation of free radicals and lipid peroxidation processes in trichinellosis. The oxidative-antioxidant status of male Wistar rats infected or uninfected with Trichinella spiralis (Nematoda) and supplemented or unsupplemented with Sel-plex (Alltech) was tested through blood biomarkers. Sel-plex was applied to restore antioxidant defense system.

Oxidative-antioxidant status of Fasciola hepatica-infected rats supplemented with zinc. A mathematical model for zinc bioaccumulation and host growth.

The oxidative-antioxidant status of male Wistar rats infected or uninfected with Fasciola hepatica (Trematoda) and supplemented or unsupplemented with 2Gly.ZnCl(2).2H(2)O was tested through liver biomarkers.
