The present study investigated the benefits of tumescent anesthesia with lidocaine in dogs undergoing mastectomy, seeking the patients' comfort and their postoperative recovery. Seven animals, with different weight and breed, who had cancer in the region of mammary chain underwent mastectomy surgery. All animals received the same anesthetic protocol being used as the association between acepromazine and morphine doses of 0.04mg.kg-1 and 0.4mg.kg-1 (IM), respectively. After 15 minutes a catheter was placed in the cephalic vein and induction with propofol 4mg.kg-1 and 0.2mg.kg-1 followed by maintenance with isoflurane anesthesia was done. After instrumentation, we proceeded to the tumescent anesthesia technique with ice-cold solution consisting of Ringer's lactate, lidocaine 2% without epinephrine and adrenaline in a total volume of 15mL.kg-1. The average duration of the procedure was 74±18 minutes. The plasmatic peak of lidocaine was between 30 and 60 minutes after infiltration. The rescue analgesic was performed after approximately seven hours of infiltration. It can be concluded that the tumescent anesthesia with lidocaine should be considered as a constituent of anesthetic and analgesic protocol in dogs undergoing mastectomy surgery providing parameter stability, safety and good quality postoperative recovery.

This study aimed to describe and compare the ultrasonographic alterations in dogs' eyes submitted to facectomy with or without intraocular lens implant (IOL), to assist in the diagnosis of possible alterations related to the surgical procedure and IOL implantation. Nineteen dogs with cataract (21 eyes) were submitted to phacoemulsification and late postoperative evaluation (at five years). The animals were initially submitted to complete ophthalmological exams which preceded the sonogram. Dogs were divided in three groups: (CA) aphakic dogs (n= 11); (PP) pseudophakic dogs with implantation of two IOLs in piggyback (n=5) and (PL) pseudophakic dogs with implantation of a veterinary IOL (n = 5). The ultrasound was carried under the administration of a topic local anesthetic, with a multi frequency linear transducer of 10 MHz. Biometric eye measurements were also performed. The clinical alterations observed were IOL dislocation, retinal detachment, asteroid hyalosis, and vitreous degeneration. Ultrasound examination was an excellent diagnostic tool, as it was possible to confirm and classify these changes. The piggyback implant reduced the measurements between the ciliary body and the vitreous chamber obtained from the ocular biometry when compared to other usual procedures, with no difference between the axial length and the anterior chamber.

The adoption of management practices that reduce water losses is essential to conserve moisture and improve soil temperature, especially in arid and semiarid environments of the Brazilian Northeast, characterized by high evapotranspiration and the adoption of irrigation with saline water, which harms growth and yield of commercial crops. Given these factories, an experiment was conducted in Nova Floresta, Paraiba, from August 2010 to February 2011 in Oxisoil, in order to evaluate the production of bell pepper and soil moisture in grooves with side trim, and application of biofertilizer and mulch cattle. The experimental design was randomized blocks with four replications using a factorial 2 x 2 x 2 for the ground beef with and without biofertilizer, with and without residues of sisal fiber (Agave sisalana), with and without the side facing the grooves, to reduce lateral water losses by infiltration of water with polyethylene plastic film. From the results, the lining of the lateral grooves provided higher values of soil moisture, number of fruits, fruit mass, plant production and productivity, bell pepper plants. It was also found that the combination of biofertilizer and mulch the ground beef remained wetter in the first 15 cm depth.

O objetivo deste trabalho foi avaliar o pH e a densidade óptica das soluções de azul de metileno a 1% e 2% (tamponadas e não tamponadas) após a imersão de três cimentos endodônticos. Foram preparados oitenta espécimes de cada cimento endodôntico (Endofill, AH Plus e Sealapex), os quais foram imersos nas soluções corantes. As soluções foram analisadas antes e após a imersão dos materiais nos períodos de tempo de 0, 24, 48 e 72h. Foram realizadas avaliações do pH utilizando um pHmetro e da densidade óptica utilizando um espectofotômetro ajustado em 596nm. Os dados de pH foram analisados através de estatística descritiva e os dados da densidade óptica foram analisados pela ANOVA e teste de Tukey 5%. Pôde-se verificar que as soluções corantes de azul de metileno tamponadas e não tamponadas apresentaram pequena variação nos valores de pH e densidade óptica antes do contato com os cimentos endodônticos. As soluções corantes não tamponadas apresentaram valores de pH menores que as tamponadas, independentemente do contato com qualquer cimento endodôntico. Os cimentos endodônticos promoveram alterações nos valores de pH das soluções corantes, sendo que as maiores alterações ocorreram nas soluções não tamponadas. Ocorreram alterações nos valores da densidade óptica das soluções corantes tamponadas e não tamponadas nos diferentes períodos de tempo de análise, sendo diferentes para cada cimento endodôntico utilizado

O Lago Azul (Rio Claro – SP), oriundo da canalização do Córrego Servidão, vem sofrendo com problemas de inundação, infiltração, erosão e contaminação das águas por esgoto. Alguns dos compostos mais despejados nas águas de rios, e responsáveis por tais problemas de contaminação são os detergentes biodegradáveis, que têm sido alvo de críticas, não apenas devido aos problemas de biodegradação, mas também devido ao fato de provocarem o fenômeno conhecido como eutrofização. A preocupação com a possível contaminação das espécies do Lago Azul levou a prefeitura de Rio Claro, junto da SABESP, a iniciar estudos das águas e sedimentos do Lago Azul. Visando essa preocupação o projeto pretende analisar os efeitos da água do Lago Azul e de uma diluição de detergentes em indivíduos de Prochilodus lineatus (Curimbatá), comparados a um controle exposto a água pura clorada do poço artesiano situado no Campus da UNESP de Rio Claro. O projeto procurou caracterizar o epitélio que recobre as escamas da espécie tratada, haja vista que se trata de uma estrutura inexplorada na literatura. A partir desses dados, análises foram realizadas através da detecção de possíveis alterações morfológicas na histologia e histoquímica das células epiteliais de escamas para avaliar os efeitos dos possíveis agentes contaminantes. Para as análises histológicas o material foi processado em resina para as técnicas de Alcian e PAS para detecção de polissacarídeos ácidos e básicos, Azul de Bromofenol para detecção de proteínas, Picrossirus Red para detecção de fibras colágenas I e III e Hematoxilina-Eosina para analisar alterações morfológicas. Os dados coletados foram analisados com auxílio de um microscópio Leica DM 2000, dotado de câmera para captura de imagens

Contamination of rivers and lakes, waste disposed by infiltration into the soil as fertilizer, for example, has been highlighted around the world, since such compounds can contain toxic elements, causing changes in aquatic and/or terrestrial ecosystem. Due to the possible presence of these elements in these wastes, it is possible assess damage to organisms exposed through breaks in genetic material and mutations. In this sense, this work aimed at exploring the cytotoxic, mutagenic and genotoxic vinasse pontential, residue used as fertilizer, from the processing of sugar cane into alcohol, using fish (Oreochromis niloticus - Cichlidae) as a test organism. The individuals were exposed to different dilutions of vinasse in the water and later carried out analysis of their erythrocytes using the micronucleus test and nuclear abnormalities associated and the comet assay. In the first bioassay, tilapia exhibited 5% and 10% vinasse concentrations died after 48h. The number of micronucleated erythrocytes was statistically significant for the 1% vinasse concentration and also for nuclear abnormalities such as broken-egg and nuclear bud, when compared with negative and positive controls; were also significant lobed type erythrocytes, when compared to the negative control. The test results of the comet assay were not significant for 1% vinasse when compared to the negative control, due to the high rate of comets with damage control, which is unusual. The same was observed for changes as notched and blebbed type. In the second chemical analyzes conducted, the detection of heavy metals in the vinasse sample, charged only the presence of copper and chromium, the latter with a concentration 89 times higher than in the first test. Differentially the first bioassay, fish exposed to dilution of 5% did not die... (Complete abstract click electronic access below)
