Elemental concentrations in fishes from the Salton Sea,Southeastern California

The Salton Sea is a 93 000 ha saline lake fed by drainage water from more than 283 000 ha of irrigated lands in the Imperial and Coachella valleys of California. A total of 21 composite samples of four recreationally important fish species — bairdiella (Bairdiella icistia), orangemouth corvina (Cynoscion xanthulus), sargo (Anisotremus davidsoni), and Mozambique tilapia (Tilapia mossambica) —collected there were analyzed for 14 elements. Twelve of these elements were detected in one or more of the samples: As, B, Co, Cu, Fe, Hg, Mo, Ni, Pb, Se, V, and Zn. Cadmium and Tl were not detected. The ranges in concentrations of elements in the skinless fillets of bairdiella, corvina, and sargo, and in whole bodies of all four fishes were comparable to levels that are typically measured in saltwater fishes. Only Se concentrations were elevated (as much as 14 µg g^?1 dry weight in both fillets and whole bodies) in this series of samples. Elevated concentrations of Se have already led to public health advisories concerning the consumption of fish and might eventually cause the demise of fish populations from toxic effects.     

Blood chemistry as an aid to diagnosis of combined copper and magnesium deficiency in single-suckler calves

Calcium, magnesium, copper, inorganic phosphorus, sodium, potassium, total protein, albumin, globulin, urea, glucose, packed cell volume and haemoglobin in the bloods of apparently health single-suckler calves were frequently measured. Values were within normal ranges except magnesium and copper which became subnormal as lactation advanced and closely approached values of single-suckler calves clinically affected with combined hypomagnesaemic tetany and hypocuprosis which responded to magnesium and copper therapy.

Kurzfassung Die Autoren bestimmten häufig den Gehalt von Kalzium, Magnesium, Kupfer, anorganischem Phosphor, Natrium, Kalium, gesamtem Protein, Eiweiss, Globulin, Harnstoff, Glukose, Hämatokrit und Hämoglobin im Blut anscheinend gesunder Saugkälbern. Die bestimmten Werte lagen im je mehr die Laktation weiterschritt, und näherten sich den Werten von Saugkälbern, die von dem gleichzeitig auftretenden Magnesium und Kupfermangel im Blut verursachtem Starrkrampf befallen waren, und die auf eine Magnesium und Kupfer-Thermapie reagieriten.

Resume Le calcium, le magnésium, le cuivre, le phosphore inorganique, le sodium, le potassium, les proteines totales, les albumines, les globulines, l'urée, le glucose, le hématocrite et l'hémoglobine dans le sang de veaux allaités et apparemment en bonne santé ont été mesurés. Les valeurs no dépassaient pas les limites normales sauf dans le cas du magnésium et du cuivre, qui devenaient subnormales au fur et à mesure que la période de lactation avancait, pour se rapprocher aux valeurs des veaux allaités atteints cliniquement d'une combination de la tétanie hypomagnésémique et al l'hypocuperose que réagissent à une thérapie de magnésium et de cuivre.

Riassunto Gli autori hanno spesso definito il contenuto in calcio, magnesio, rame, fosforo inorganico, sodio potassio, proteina totale albumina, globulina, urea, glucosio, ematocrita, ed ematoglobulina del sangue di vitelli poppanti apparentemente sani. I valori erano normali eccetto quelli del magnesio e del rame che diventarono subnormali man mano che progrediva la lattaxione ed avvicinarono i valori dei vitelli lattanti clinicamente affetti dalla tetania ipomagnesemica combinata alla ipocuperosi e che rispondevano ad una terapia con magnesio e rame.

     

Gastric carcinoma in a dog

An 8–year-old castrated male Bassett hound had been vomiting intermittently for 3 weeks. In addition, clinical signs of anorexia, weight loss, dehydration, depression and anterior abdominal pain were noted. Gastro-scopic and radiographic examination revealed a mass at the pyloric region of the stomach. Clinical remission followed surgical excision of gastric carcinoma, with recurrence of vomiting 4 months after surgery. At necropsy, the pyloric region of the stomach was markedly thickened, rigid, scirrhous and had an excavated ulcer. The pathological diagnosis was a poorly differentiated, diffuse gastric carcinoma with metastasis to regional lymph nodes.     

Drivers of fine-scale avian functional diversity with changing land use: an assessment of the effects of eco-estate housing development and management

Landscape Ecology - The effects of changing land use, and especially urbanisation, on species and functional diversity are of global concern. Eco-estates are a form of urban housing development...     

Estimation of the effect of lead and cadmium ions on fluctuating asymmetry in leaves of the common bean (Phaseolus vulgaris L.)

The effect of lead and cadmium ions on the fluctuating asymmetry of the side leaflets’ central veins of the common bean (Phaseolus vulgaris L.) was estimated. The impact of heavy metals on the parameter with the lead or cadmium content in the ground in the concentration of 650 mg/kg or 10 mg/kg respectively was not revealed.
