Estudou-se o quadro clínico do veneno decorrente do envenenamento por Tityus fasciolatus e sua ação refletida nos componentes hematológicos no modelo murino. Para o estudo do perfil hematológico, foram utilizados 54 camundongos Swiss CF1, machos, com 30g, distribuídos em três grupos (G) (n=18) inoculados via subcutânea com: 50µL de PBS (G1); 24µg de veneno de T. fasciolatus (G2) e 8µg de veneno de T. serrulatus (G3). Cada grupo foi subdividido em três subgrupos (n=6) de acordo com o momento da coleta de sangue que foi estipulada em uma, oito e 24h após a inoculação do veneno, e foram realizados o hemograma e a dosagem de proteínas totais e fracionadas. O veneno de T. fasciolatus na dose de 24µg causou piloereção, comportamento nociceptivo, secreção nasal e oral acentuada, dispneia, prurido na face e reflexos exacerbados. No exame hematológico, foram observadas policitemia relativa e leucocitose com linfocitose.

The aim of this study was to evaluate the clinical picture caused by Tityus fasciolatus and its action reflected in mouse blood profile. To study the blood profile, 54 Swiss CF1 mice, male, 30g, distributed into three groups (G) (n= 18) and inoculated subcutaneously with: 50µl PBS (G1), 24µg of venom of T. fasciolatus (G2) and 8µg venom T. serrulatus (G3) were used. Each group was subdivided into three subgroups (n= 6) according to the time of blood collection that was set at 1h, 8h and 24h after inoculation of the venom, and blood profile, total protein and fractionated were evaluated. The venom of T. fasciolatus at a dose of 24µg caused piloerection, behavior pain, nasal and oral sharp, dyspnea, rash on the face and exaggerated reflexes. In blood profile were observed relative polycythemia, leukocytosis with lymphocytosis.

Radiography (conventional and contrasted - canalography) and audioelectrophysiologic (impedance audiometry) tests were correlated with otitis media in 12 middle ear affected and 12 healthy dogs. When comparing both diagnostic methods, it was found that the reliability in the detection of otitis media in dogs was 100% for the first and 58.3-60.0% for the latter. Thus, it was possible to attest that the impedance audiometry was the most accurate method in the identification of otitis media in dogs when compared with radiographic assessments.

Foram avaliadas as técnicas radiográficas dentárias intra (TIB) e extrabucal (TEB) em 50 cães com doença periodontal, no intuito de padronizar os procedimentos de diagnóstico dessa síndrome. A TIB revelou que 16 animais não apresentaram lesões ósseas visíveis, enquanto a TEB apontou que 39 pacientes foram negativos para as mesmas lesões. Em resumo, a TIB foi mais eficaz na detecção de sinais radiográficos, especialmente as chamadas lesões finas, que a TEB, sendo a técnica de escolha na síndrome periodontal.

The intra (IOT) and extraoral (EOT) dental radiographic techniques in 50 dogs with periodontal disease were compared to standardize the most appropriate procedure for accurate diagnosis of abnormalities that occur in this syndrome. For IOT, 16 animals showed no visible radiographic lesions, whereas in EOT, 39 patients were negative for the same radiographic lesions. For incisor and canine teeth, IOT presented the highest sensitivity of lesion detection, while there was no significant difference for the premolar and molar teeth group. It is concluded that IOT is more effective in detecting radiographic signs (especially the so-called thin lesions) than the EOT and should therefore be the technique of choice in the periodontal syndrome.

Avaliou-se o hemograma de 12 cães adultos, saudáveis (14,2±5,4kg) após a inoculação de veneno do escorpião amarelo (Tityus serrulatus). Os animais foram distribuídos em dois grupos (G), com seis em cada: os do GI foram usados como controle e receberam 0,5mL de salina tamponada com fosfato (PBS) por via subcutânea (SC) na face medial da coxa esquerda (FMCE), e os do GII receberam veneno liofilizado do T. serrulatus (250µg/kg) diluído em PBS por via SC na FMCE. Foram realizadas colheitas de sangue com anticoagulante EDTA a 10% antes da inoculação do veneno (T0) e após 2h, (T1), 6h (T2), 12h (T3), 24h (T4), 48h (T5) e 72h (T6), para contagem de eritrócitos, leucócitos e plaquetas em aparelho contador eletrônico e esfregaços sanguíneos para contagem diferencial de leucócitos. Houve aumento significativo (P<0,05) dos valores de eritrócitos, volume globular e hemoglobina 2h e 6h após o envenenamento, devido à contração esplênica decorrente da dor local causada pelo veneno e pela liberação de catecolaminas. Foi observada leucocitose por aumento significativo (P<0,05) de neutrófilos e linfócitos 2h e 6h após o envenenamento. Concluiu-se que o veneno de Tityus serrulatus na dose de 250µg/kg, é capaz de aumentar os valores do eritrograma e do leucograma dos cães, provavelmente devido à dor local, com liberação de catecolaminas.

The canine blood profile after scorpion envenomation was evaluated using 12 healthy mongrel male dogs (14.2±5.4kg) distributed in two groups, with six animals in each: group I (control group) and group II (venom group). The lyophilized yellow scorpion (Tityus serrulatus) venom (250µg/kg) diluted in 0.5mL phosphate buffered saline (PBS) was given to group II animals by subcutaneous injection, in the medial face of the left thigh. Group I animals received only 0.5mL of PBS, by subcutaneous injection, in the medial face of the left thigh. Blood samples were collected with EDTA before (T0) and 2 (T1), 6 (T2), 12 (T3), 24 (T4), 48 (T5), and 72h (T6) after envenomation. Significant increases (P<0.05) in erythrocytes counting, hematocrit and hemoglobin concentration, 2 and 6h after envenomation were observed. Leukocytosis with significant increases (P<0.05) of neutrophils and lymphocytes 2 and 6h after envenomation was found. Then, T. serrulatus venom may induce alterations in blood profile in dogs, probably due to spleen contraction evoked by pain and catecholamines releasing.

The efficacy of keto acids and essential amino acids on a two-year-old female dog, Labrador, suffering from Leishmaniasis and acute renal failure was evaluated by clinical and laboratorial analyses based on urea and creatinine dosages. An improving in the animal general condition and an increasing in the appetite, activity and weight gain, were observed and favorably contributed to the treatment of the primary disease. Ketoanalogueswere oraly administered during 76 days and the levels of urea and creatinine remained within acceptable limits, even after this period of time. Ketoanaloguescontributed positively for the treatment of acute renal failure and appears to be an important alternative for the leishmaniasis treatment.
