“…The results of this study showed the highest TotalN and a two-and three-fold higher VN and BlebN frequencies in fish from Site A, probably caused by the mixture of pollutants. Namely, literature data showed that synergistic effect of pollutants is more deleterious than their isolated influence (16).…”

Macedonian Veterinary ReviewThe strong negative anthropogenic pressure on the River Bregalnica resulted in the increase of pollution in the river ecosystem. The aim of this study was to evaluate if aquatic pollutants generate genotoxic effects in barbel (Barbus peloponnesius). Thirty individuals were collected from three localities along the river: one control site and two locations in the middle and lower course of the river with the presence of different pollution sources. Blood smears were stained with May-Grünwald/Giemsa method and the frequency of micronuclei, vacuolated nuclei, binuclei, blebbed nuclei and notched nuclei expressed in per mill was recorded. In fish collected from the control site, the investigated erythrocyte nuclear abnormalities revealed lowest values compared to polluted sites. In general, significantly higher values for erythrocyte deformations, including micronuclei, were noted in the middle and lower part of the river. Significantly higher values of vacuolated and blebbed nuclei were detected in fish from the middle course of the river, while at the lower course the frequencies of occurrence of micronuclei and notched nuclei were significant compared with control site. The middle course of the River Bregalnica has more diverse pollutants compared to the lower course, and consequently the highest frequency of all nuclear deformations was found in barbel from the middle course of the river. Obtained results suggest that pollutants draining into the Bregalnica river ecosystem display a genotoxic effect on the local barbel population.

Oxidative stress and DNA damage are involved in the glyphosate-based herbicide toxicity. Uncaria tomentosa (UT; Rubiaceae) is a plant species from South America containing bioactive compounds with known beneficial properties. The objective of this work was to evaluate the antioxidant and antigenotoxic potential of UT extract in a model of acute exposure to glyphosate-Roundup® (GR) in zebrafish (Danio rerio). We showed that UT (1.0 mg/mL) prevented the decrease of brain total thiols, the increase of lipid peroxidation in both brain and liver, and the decrease of liver GPx activity caused after 96 h of GR (5.0 mg/L) exposure. In addition, UT partially protected against the increase of micronucleus frequency induced by GR exposure in fish brain. Overall, our results indicate that UT protects against damage induced by a glyphosate-based herbicide by providing antioxidant and antigenotoxic effects, which may be related to the phenolic compounds identified in the extract.
