Demodicose em cães atendidos em um hospital veterinário universitário / Demodicosis in dogs attended in a university veterinary hospital

A sarna demodécica ou demodicose pode ser definida como uma dermatopatia parasitária, caracterizada pela presença exacerbada de ácaros comensais da pele de cães, Demodex spp. Essa doença pode ser classificada clinicamente como localizada ou generalizada, conforme a dimensão e distribuição das lesões. O diagnóstico é realizado por raspado cutâneo profundo. Este estudo teve como objetivo descrever a casuística da demodicose em cães atendidos no Hospital Veterinário da Universidade Federal do Piauí (HVU/UFPI), no período de 2015 a 2017. Foram analisadas 67 fichas sugestivas da doença e, destas, 30 tinham no seu diagnóstico confirmatório a presença do parasito. O levantamento foi obtido através das fichas de atendimento de cães com sarna demodécica, onde incluíam o número de registro, sexo, idade e raça do animal, além da classificação da doença e tratamento realizado. Os resultados indicaram que cães machos apresentaram maior prevalência da enfermidade, representando 63,3% dos casos. A maioria dos animais acometidos eram jovens (53,3%), sendo que os cães sem raça definida (SRD) foram os mais afetados (43,3%), seguidos da raça Pinscher (20,0%). A forma generalizada da doença foi a de maior ocorrência neste estudo (80,0%), e o tratamento oral foi o de maior indicação nas fichas de atendimento dos cães parasitados. Conclui-se que a demodicose foi frequente nos cães atendidos no HVU/UFPI durante o período do estudo, com maior ocorrência em animais jovens, machos, SRD e maior representatividade da forma generalizada da doença.

Demodectic scab or demodicosis can be defined as a parasite dermatopathy, characterized by the exacerbated presence of dog skin commensal mites, Demodex spp. This disease can be classified as localized or generalized, depending on the size of the lesions. The diagnosis is made by deep scraping of the skin. This study objective to describe cases of demodicosis in dogs attended at the Veterinary Hospital of the Federal University of Piauí (HVU/UFPI), from 2015 to 2017. Sixty-seven records were analyzed suggesting the disease and, of these, thirty had confirmatory diagnosis the presence of the parasite. The survey was obtained through the records of dogs with demodectic scab, which included the registration number, sex, age and race of the animal, besides the classification of disease and treatment performed. The results indicated that male dogs presented a higher prevalence of the disease, representing 63.3% of the cases. The majority of the affected dogs were young (53.3%), and the mixed breed dogs were the most affected (43.3%), followed by the pinscher breed (20.0%). The generalized form of the disease was the most frequent in this study (80.0%) and the oral treatment was the most indicated in the records of care of the dogs. It was concluded that demodicosis was frequent in dogs treated at HVU / UFPI during the study period, with a higher occurrence in young male animals, SRD and greater representativity of the generalized form of the disease.

Avaliação da atividade androgênica e antiandrogênica promovida pelo extrato etanólico da richeria grandis vahl. (phyllanthaceae) em ratos / Richeria grandis Vahl. (Phyllanthaceae) ethanolic extract: androgenic and anti-androgenic activity evaluation in rats

The Richeria grandis known is for its aphrodisiac properties and due to its wide empiric use well as thelack of gender Richeria studies the objective of this study was to evaluate the androgenic and anti-androgenicactivity of this plant. They were used in this study 64 male Wistar rats, castrated, divided into eight groups. Thegroups for the study of androgen activity were treated with boiling water over corn R. grandis ethanolic extractoil at doses of 75, 150 and 300 mg / kg and groups of antiandrogenic activity received corn oil, distilled waterand ethanol extract at doses of 75, 150 and 300 mg / kg associated with testosterone. It was found that theethanol extract of R. grandis in the tested doses did not differ statistically from the negative and positive controlsdid not thus demonstrating androgenic activity or antiandrogenic.(AU)

Angiotensina-(1-7): Efeito na maturação in vitro de oócitos ovinos / Angiotensin- (1-7): Effect on in vitro maturation of sheep oocytes

Aimed to evaluate the effect of addition of angiotensin-(1-7) in the middle of in vitro maturation ofsheep oocytes. Seventy-four oocytes of sheep ovaries slaughtered in fridg were matured in vitro: I - control(n=22), II - Ang-(1-7) at 1 uM (n=24), III - Ang-(1-7) at 1 uM+A-779 at 1uM (n=28) in microdropletscontaining 100 µL of maturation medium plus 10% fetal bovine serum under mineral oil in the incubatoratmosphere 5% CO2 in air at 38.5°C for a period of 18 hours. After this period, the oocytes were denuded andobserved the extrusion of the first polar body. Statistical analysis was performed using the t test at 5%probability. The addition of angiotensin-(1-7) at 1 uM, as well as the addition of angiotensin-(1-7) at 1 uMtogether with its specific antagonist A-779 at the same concentration, decrease the in vitro maturation rate ovine oocytes.(AU)
