Opis:
Here we report the industrial pollution effects due to cadmium on the reproductive health of Mytilus galloprovincialis. Mussels were removed from the biofouling of a Conatex panel after one year exposition at a polluted site near a disposal metallurgical factory. A high cadmium bioaccumulation was observed in the testis of mussels housed at the polluted site, with respect to a control site, as determined by inductively coupled plasma-mass spectrometry, along with a 10 fold increase in metallothionein 20 kDa gene (mt20) expression levels determined by qPCR. Furthermore, mussels transferred into laboratory tanks from the reference site, and exposed to 1.5, 5 and 10 µM CdCl2, revealed a 1.7, 3.2 and 4.5 fold expression increase in the testis mt20, respectively, and a positive correlation with cadmium bioaccumulation was found. To evaluate a potential detrimental risk of such alterations on spermatozoa, we carried out electrophoretic analyses on their protamine-like proteins. As determined by AU-PAGE, after 1.5 µM CdCl2 exposure, protamine-like proteins also display major alterations with respect to those obtained after 5 and 10 µM CdCl2 exposure. All protamine-like proteins isolated from the polluted biofouling were in an aggregated form and displayed the same reduced DNA binding affinity of the protamine-like proteins obtained after 1.5 µM CdCl2 as demonstrated EMSA with sperm genomic DNA. Our results contribute to the studies concerning cadmium induced testis alterations and highlight protamine-like proteins' analysis as an emerging biotechnique for cadmium impact assessment on Mytilus galloprovincialis, for the sensitivity of the in vivo and in vitro changes of protamine-like proteins' state and their DNA binding affinity.

Opis:
An active biomonitoring study was carried out on the Algerian west coast using wild reference mussels (Mytilus galloprovincialis) sampled from the Kristel (K) site and transplanted in net cages during one month (between May and June 2007) to Oran Harbour (OH) and Mostaganem Harbour (MH), areas characterised by high levels of urban and industrial pollution. The biological response of the mussels was evaluated by their condition index and the use of a general stress biomarker (evaluation of lysosomal membrane stability: the neutral red retention time (NRRT) method), a genotoxic effects biomarker (determination of micronuclei (MN) frequency) and a neurotoxic effects biomarker (determination of the acetylcholinesterase (AChE) concentration). Compared to the K reference specimens, OH and MH caged mussels presented a significant decrease of NRRT in lysosomal haemocytes (56.45±26.48 min and 67.25±22.77 min, respectively) (78±16.97 min for K mussels), an MN frequency respectively 7.3 and 9 times higher in the haemocytes and the gill cells of the OH caged mussels, and 7.2 and 6.4 times higher in the two tissues of the MH caged mussels. Significant inhibition of AChE activity was noted in the gills (16.93±3.1 nmol min−1 mg prot−1) and the digestive gland (7.69±1.79 nmol min−1 mg prot−1) of the OH mussels, but only in the gills (23.21±5.94 nmol min−1 mg prot−1) of the MH mussels, compared to the organs of the K control specimens (35.9±6.4 nmol min−1 mg prot−1 in the gills and 11.17±0.49 nmol min−1 mg prot−1 in the digestive gland). This study reflects the interest in such in situ biomonitoring assays and the utility of these biomarkers for assessing the effects of pollution in the Algerian coastal marine environment.

Opis:
Diets supplemented with Mytilus galloprovincialis from polluted and non-polluted waters and their influence on zinc content in liver of rats loaded with cholesterol. Mussels may reflect the environmental problems that the ecosystem faces. Mytilus galloprovincialis is widely used as an indicator of water pollution in biological monitoring studies. These mussels are filter feeders and may accumulate important ecosystem pollutants what in turn may pose a potential risk to other organisms in the food chain. The aim of the study was to determine zinc content in the diets supplemented with mussels from polluted and non-polluted areas and in the livers of rats fed these diets for 30 days. The zinc content in the diets with mussels from contaminated and noncontaminated waters and in rat livers was examined using a flame atomic absorption spectrophotometry (Perkin-Elmer 1100B). The slight increase in zinc content from 73.2 ±1.2 mg/ /kg in ch diet (control with 1% of cholesterol) to 77.2 ±0.5 mg/kg in the diet with mussels from polluted site was found, but zinc content in all diet was within the normal limits reviewed by McDowell (1992) – 40 to 100 ppm. Zinc content in the diet supplemented with mussels from nonpolluted site (73.7 ±3.7 mg/kg) was similar to that found in ch diet. It can be concluded that cholesterol does not affect zinc bioaccumulation. However, prolonged consumption of mussels from contaminated sites may increase accumulation of zinc in the liver of rats.
Diety z dodatkiem Mytilus galloprovincialis z wód niezanieczyszczonych i zanieczyszczonych oraz ich wpływ na zawartość cynku w wątrobie szczurów obciążonych cholesterolem. Małże mogą odzwierciedlać problemy środowiskowe, przed którymi stoi ekosystem. Mytilus galloprovincialis jest szeroko wykorzystywany w biomonitoringu. Małże te są filtratorami i mogą kumulować w tkankach ważne zanieczyszczenia z ekosystemu, co z kolei może stanowić potencjalne zagrożenie dla innych organizmów w łańcuchu troficznym. Celem badania było określenie zawartości cynku w dietach z dodatkiem małży z obszarów niezanieczyszczonych i zanieczyszczonych oraz w wątrobach szczurów żywionych tymi dietami przez 30 dni. Zawartość cynku w dietach z małżami z zanieczyszczonych i niezanieczyszczonych wód i wątrobach szczurów oznaczono metodą płomieniowej absorpcji atomowej (Perkin-Elmer 1100B). Wykazano nieznaczny wzrost zawartości cynku w diecie z małżami z wód zanieczyszczonych (77,2 ±0,5 mg/kg) względem grupy ch – kontrola z 1% udziałem cholesterolu (73,2 ±1,2 mg/kg), ale zawartość cynku we wszystkich dietach mieściła się w granicach normy podanych przez McDowell (1992) – 40–100 ppm. Zawartość cynku w diecie z małżami z obszarów niezanieczyszczonych (73,7 ±3,7 mg/kg) była zbliżona do zawartości w diecie grupy ch. Podsumowując wyniki, można stwierdzić, że cholesterol nie wpływa na bioakumulację cynku. Jednak, długotrwałe spożywanie małży z wód zanieczyszczonych może zwiększyć akumulację cynku w wątrobie szczurów.

Opis:
The Algerian west coast is the prime recipient ofsev eral forms of pollution; hence, the necessity for an impact assessment of this coastal pollution using a suite ofr ecommended marine biomarkers, including lysosomal membrane stability in living cells by the Neutral Red Retention Time (NRRT) method, the evaluation ofmicron ucleus (MN) frequency, and the determination ofacet ylcholinesterase (AChE) activity in mussels Mytilus galloprovincialis, sampled from the large, polluted Oran Harbour (OH) and the Maˆarouf( Mrf) marine mussel farm between July 2005 and April 2006. The difference in the variations oft he annual physical parameters between OH and Mrfco rresponds to the influence ofthe domestic and industrial sewage discharged by the city ofO ran. The biological data ofthe mussels (condition index, protein content) recorded at both sites were related to their natural reproductive cycle. This indicated that intrinsic variation between the sites due to different mussel development phases was minimal. The variation in the AChE activity of some organs ofO H and Mrfm ussels, with minimal inhibition in July and a higher NRRT recorded in the granular haemocytes in the Mrfthan in the OH mussels during the autumn and spring, depends on the quality ofthe biotope and on generic stress factors. Moreover, the variation in MN frequency, in general reflecting a non-significant seasonal and spatial genotoxic effect ofthe contamination at the two sampling sites, requires further investigations regarding biotic and abiotic variations.
