A peptide fraction from hardened common beans () induces endothelium-dependent antihypertensive and renal effects in rats.

Beans reached the research spotlight as a source of bioactive compounds capable of modulating different functions. Recently, we reported antioxidant and oxidonitrergic effect of a low molecular weight peptide fraction (<3 kDa) from hardened bean () and , which necessitate further assessments. This work aimed to evaluate the hypotensive effect and the involved physiological mechanisms of the hardened common bean peptide ) in normotensive (Wistar) and hypertensive (SHR) animals.

[Canine visceral leishmaniasis in dog from Caldas Novas, Goiás].

The objective of the present work was to describe a visceral case of leishmaniasis in a dog from Caldas Novas, GO, region until then considered as a disease free area. The animal, attended in the Veterinarian Hospital of the Federal University of Goiás, presented loss of weight, alopecic area of irregular format at the nasal back, onicogrifosis, atrophy of the heads muscles and failure of the right popliteus lymphonode. For the laboratorial diagnosis, samples were collected by biopsy from the complete skin of the auricular region, by punsion from the popliteus lymphonode for preparation of Giemsa stained blades and 5 mL of the blood were also collected for serum diagnosis.
