Chemotherapy agents have some undesirable and non-selective cytostatic effects. Considering that kidneys are vulnerable to drug-induced toxicity, this study evaluated renal injury caused by vincristine sulfate (VS) in 12 female dogs diagnosed with transmissible venereal tumor (TVT). The animals were treated with VS (0.025 mg/kg IV) every 7 days for 4 weeks. During treatment, the animals were subjected to clinical examination, blood count, serum measurement of symmetric dimethylarginine (SDMA), blood urea nitrogen (BUN), creatinine, alanine aminotransferase, and alkaline phosphatase. In addition, urinalysis and urinary gamma-glutamyl transferase (GGT) measurements were performed. All parameters were determined three times: before beginning the treatment (T0), after 14 days (T1), and after 28 days (T2). During the study period, there were no changes in serum urea or creatinine levels, urine specific gravity, or persistent proteinuria. Furthermore, urinary GGT measurement did not indicate tubular lesions, and consistent elevation of SDMA was found in only one patient above the reference range. The results showed that weekly therapy with VS as a single agent for 28 days does not induce renal injury in most cases.

Fourteen female dogs diagnosed with pyometra were studied at three separate times: at diagnosis (T0) and 24 h (T1) and 10-15 days (T2) after ovariohysterectomy (OH). The means of the markers, symmetric dimethylarginine (SDMA) (17.71 to 26.54 μg/dL) and the urinary gamma-glutamyl transferase to creatinine ratio (uGGT/uCr) (1.06 to 2.62 U/mg), varied, showing an increase with time. Further, the elevation of gamma-glutamyl transferase (uGGT) (56.61 to 128.12 U/L) and the urinary protein to creatinine ratio (RPC) (0.26 to 1.24) was evident at T0 and T1. A reduction in the means of RPC, uGGT, and uGGT/uCr was observed 10-15 days after OH. Despite the elevation of these markers, the concentration of creatinine (1.11 to 1.40 mg/dL), urea (40.07 to 67.16 mg/dL), and urinary specific gravity (1.027 to 1.028) only presented slight variation. In canine pyometra, complications secondary to acute renal injury may be present that may be mild and transient in most treated animals. As elevation in SDMA and RPC preceded changes in creatinine levels for the evaluation of glomerular filtration, tubular markers could assist in the early identification of renal damage in canine pyometra.

Os cães desde sua domesticação vêm servindo ao homem de diversas maneiras, uma importante função é como cão policial, principalmente como farejadores e cães de apreensão. Apresentando suas particularidades olfatórias, o cão farejador pode agir de maneira rápida e eficaz como detectores de odores de interesse, como de explosivos, narcóticos e até busca de pessoas desaparecidas sob escombros. Evidências olfativas caninas, já foram utilizadas nos tribunais a partir do alinhamento do odor deixado no local do crime com um possível suspeito. O cão também pode ser entendido como um instrumento de menor potencial ofensivo, podendo ser treinados na técnica de mordida e apreensão, segurando o suspeito até o comando de soltura. Aspectos relevantes sobre as características, emprego e saúde para a adequada atuação do cão policial serão descritos neste artigo afim de que se destaque a real importância de sua função na Segurança Pública dos Estados

The aim of this research was to evaluate the analgesia provided by red propolis and Mikania glomerata oral administration in 40 female dogs submitted to ovariohysterectomy (OH) compared to standard treatment with no steroidal anti-inflammatory ketoprofen. Through of a doble-blind and randomized study, the animals were divided in four different groups with 10 animals of treatments: control treatment with ketofen (CT), propolis treatment (PT), Mikania glomerata treatment (MT), and propolis-Mikania glomerata treatment (PGT). All pacients received one of these treatments two hours before OH and the pain evaluation was performed 1 (T1), 6 (T6), 12 (T12), and 24 hours (T24) after OH using University of Melbourne Pain Scale and the Glasgow Composite Measure Pain Scale. Glucose levels were also measured at the same times, except at 6 hours after OH (T6). All treatments achieved similar and satisfactory analgesia. During the experiment, only three animals were rescued, two belonging to the PT and another of the MT. Considering the lower rate of complications and no rescue necessity of in PGT and CT treatments, they were considered the most effective and safer. The combined treatment with propolis and Mikania glomerata could be a promising alternative method for OH surgery analgesia in bitches.

O plasma rico em plaquetas (PRP) é um hemocomponente produzindo a partir do plasma, visando a obtenção de citocinas e fatores do crescimento com fins terapêuticos, como a cicatrização e reparação de diferentes tecidos. Esse estudo quantificou a concentração plaquetária obtida utilizando-se de três diferentes protocolos de obtenção do PRP de 13 amostras de sangue de 7 cães hígidos. As velocidades de centrifugação utilizadas no protocolo I foram de 1ª centrifugação de 1.500 rpm e 2ª centrifugação de 3.000 rpm; no protocolo II, de 2.000 rpm e 3.000 rpm; e o protocolo III com 3.000 rpm e 4.000 rpm, respectivamente. O melhor resultado para a produção de PRP autólogo foi obtido no protocolo 1, seguido do protocolo 2, com aumentos de 116% e 83,05% após a 2ª centrifugação, respectivamente. Entretanto, os resultados obtidos na 1ª centrifugação foram superiores aos apresentados após a 2ª. centrifugação, observando elevações de 203,66% e 210,20% comparados aos valores basais.
