Cataract is the leading cause of blindness in dogs. It is defined as an opacity in the lens and is independent of resulting visual deficit. Although there are a growing number of studies related to drug therapy of cataract, the treatment is still considered exclusively surgical. Among the techniques used to remove cataract, phacoemulsification is the best performer. Anesthesia in intraocular surgery has several peculiarities, which are essential to successfully conduct phacoemulsification in dogs. In these patients, a safe and effective anesthesia requires the maintenance of intraocular pressure close to normal, preventing the activation of the oculo-cardiac reflex and complete immobilization of the eye. The appropriate conditions for such surgical procedures can be established through the use of drugs from different pharmacological groups for premedication, induction and maintenance of anesthesia, making a balanced anesthesia. This work was compiled from a careful review of the literature on anesthesia in cataract surgery. Considerations on the pre-medication, induction and maintenance of anesthesia are discussed, aiming to contribute to the phacoemulsification becomes more safe and suitable for the anesthesiologist and the surgeon as well as comfortable for dogs undergoing surgery

O Brasil possui um enorme potencial de plantas medicinais usadas popularmente e ainda pouco estudadas pela comunidade cientfica. Dentro da famlia Polygonaceae, destaca-se a espcie Polygonum punctatum Ell., conhecida popularmente como erva-de-bicho, acataia, cataia, capioba, pimenta-do brejo ou pimenta-da-gua. Essa espcie perene e encontrada em lugares midos ou inundados, desenvolvendo-se preferencialmente em solo de boa fertilidade, areno-argiloso ou argiloso e com bom teor de matéria orgânica. originria da sia e encontra-se aclimatada no Brasil em todos os Estados, particularmente no Rio Grande do Sul, Sul e Sudeste (LOPES et al., 2003). H relatos de que na medicina popular faz-se o uso de todas as partes da planta para as mais diversas finalidades, tais como: antidisentrica, antissptica, detersiva, diurtica, antitrmica, anti-reumtica, vermfuga e excelente cicatrizante de feridas e lceras. E que por ser fortemente emenagoga e abortiva, seu uso no recomendado para gestantes (MORGAN, 1984). Dentre as propriedades teraputicas relatadas, destaca-se tambm o uso no tratamento de problemas circulatrios, visto que ela estimula a circulao e diminui a fragilidade capilar, e que por isso, apresenta um efeito hemosttico bastante til no tratamento de hemorridas (TESKE e TRENTINI, 1995). No entanto, plantas medicinais utilizadas popularmente necessitam de estudos cientficos que comprovem sua eficcia, segurana e qualidade. A espcie Polygonum acre H.B.K. (sinonmia de Polygonum punctatum Ell) possui poucos estudos cientficos comprovando essa vasta utilizao na medicina popular, sendo assim, se faz necessrio estudar atentamente seus extratos e leos essenciais, bem como associar a estes, estudos fitoqumicos e de identificao anatmica e morfolgica para que no haja problemas que comprometam a qualidade e a eficcia...

The present work aimed to study the composting process using two methods of treatment, conventional and mechanized for the treatment of pruning/weeding waste and organic waste generated in the canteens of the FCT/UNESP. For this work, it was quantified the generation of the waste However, of the tests with pure organic compound, which had the best result was T1 - 70% RPC / 30% ROC, again indicating the feasibility of applying this condition in scales at the campus. The conventional treatment by composting was carried out on manual aerated piles: 70% residue pruning/weeding (RPC) and 30% organic waste from the canteen (ROC); 50% RPC / 50% ROC, 30% RPC / 70% ROC. The mechanized system consisted of a reactor of 190 liters 50% RPC / 50% ROC, with air injection from a compressor for 15 minutes daily. The parameters characterized and monitored were pH, organic matter, organic carbon, ash, nitrogen kjedahl and phosphorus. The temperature measurements were taken daily by a digital thermocouple (top, middle and base of the piles and reactor)... (Completo abstract click electronic access below)

A consequence of population growth is the increased generation of solid waste, which requires environmentally and economically viable suitable disposal sites. The scarcity of such sites makes necessary to adopt non-generation measures, reduction, reuse , recycling and treatment of solid waste before final disposal of waste. This paper presents the quantification and qualification of organic waste generated in each sector of the University Restaurant (UR) , by proposing indicators of waste generation per meal (index of waste) . Then, from the characterization of the waste management practices adopted internally, evaluates the potential deployment of the composting process for organic waste, with signaling for opportunities to improve waste management. The diagnosis of waste generation was made based on data collected during the period of 10 days. The waste were classified into 3 groups (organic, recyclable and waste) in each sector of the restaurant ( pre preparation , kitchen and tray return) . The results reveal that 33 % of the waste generated in the UR currently has the potential to be composted in a suitable place on campus. Every meal served generat approximately 124g of waste, of which 35g are organic waste of the pre preparation sector, 49g are remnants of food in the trays return and 40g are other kinds of waste, including recyclable and non recyclable. You can still get a higher percentage of compostable if the trays pre-wash is not performed with detergent and water. To minimize the generation of waste trays can be replaced by plates and skimmers and ladles can be replaced by smaller ones. The food exposed in the counter but not consumed, can be distributed to students after the restaurant is closed so this material would not be disposed in the garbage
