Ocular conditions, anti-Leishmania antibodies and total protein of the aqueous humor were studied in dogs naturally infected by Leishmania (Leishmania) chagasi. Fifty dogs were analyzed and assigned into two groups of 25 animals each. All animals were submitted to routine ophthalmic exam. Results showed that 76% of the affected animals presented ocular signs, being uveitis the predominant. The mean of total protein in the aqueous humor of animals with uveitis was higher (P<0.05) when compared to the mean of animals with other ocular signs or no clinical sign. The anti-Leishmania chagasi antibody values in plasma were superior to those found in the aqueous humor (P<0.05).Keywords: dog, Leishmania (Leishmania) chagasi, aqueous humor, antibodies, protein RESUMO Estudaram-se as condições oculares, os anticorpos anti-Leishmania e os valores de proteína total no humor aquoso de cães infectados naturalmente por

Efeito da aplicação de vinhaça nas características químicas de solos da zona da mata de Pernambuco RES UMOO objetivo do presente estudo foi avaliar o comportamento de diferentes classes de solos antes e após a aplicação de vinhaça, em ambiente sob condições controladas. Para isto, três classes de solos (Nitossolo, Argissolo e Espodossolo) representativos da zona da mata canavieira de Pernambuco, foram reproduzidas em 27 colunas de PVC de 20 x 110 cm (diâmetro x altura), mantidos os horizontes, espessuras e densidades. Aos solos foram aplicadas as doses: 0 (testemunha), 350 e 700 m 3 ha -1 de vinhaça, e aos 30 e 60 dias lâminas de lixiviação. Após esse período amostras do solo foram coletadas nas profundidades dos respectivos horizontes e submetidas a análises e determinações de K, Ca, Mg, Na, pH e Carbono orgânico (CO). Os resultados indicaram que a aplicação de vinhaça, além de elevar o pH do solo, também aumentou a concentração de K e diminuiu a de Na, exceção feita ao Espodossolo, que não apresentou alterações significativas nos parâmetros estudados.

For this, three representative soil classes (Nitosol, Argisol and Espodosol) from forest zone of Pernambuco State were reproduced in 27 PVC columns of 20´110 cm (diameter ´ height), maintaining horizons, thickness and densities similar to original soils. Vinasse was applied to the soil at rates of 0 (control), 350 and 700 m 3 ha -1 , and the leaching was collected at 30 and 60 days. After that period, soil samples were collected in the depths of respectives horizons, and submitted to analysis and determinations of K, Ca, Mg, Na, pH and organic carbon. The results indicated that vinasse application promoted a pH and K concentration increase, reducing the amount of Na in the soils, except for the Spodosol, which did not show significant alterations in the studied parameters.

Keratoconjunctivitis sicca (KCS), also known as dry eye syndrome, is an ocular surface disorder in dogs characterized by decreased production of the aqueous part of the tear film (quantitative) or by evaporative tear disorders (qualitative). 1 In dogs, most cases of qualitative KCS are due to immune-mediated disease in which the inflammatory process results in atrophy of the lacrimal glands, substitution of glandular structures for fibrous
