Neurorrafia do ramo bucal dorsal do nervo facial em coelhos com proteção de segmento intestinal alógeno

18 rabbits, New Zealand, males, adults were used for clinical and histological evaluation of repair dorsal buccal branch of facial nerve after 15, 30 and 60 days postoperatively (PO). The animals were divided into two groups for transection and 10-0 nylon monofilament epineural suture of buccal branch. In animals in Group I, the nerve was coated with protection of jejunum allograft preserved in glycerin 98% and in group II was applied epineural suture. Both groups occurred the return of movement of the upper lip from the eighth week. There was infiltrated cellular and giant cells with fibrosis unsystematic and collagen fibers of the allograft jejunum joing to the connective tissue. At 15 and 30 days of PO, the distal nerve stumps of both groups were found with degeneration wallerian and in 60 days, regenerated fibers. The repair of the dorsal buccal branch of facial nerve with the allograft wasn't significantly different between the control rabbits as to the assessment of histological and functional recovery.

Anticorpos anti-Leptospira spp. em animais selvagens do zoológico municipal de Ribeirão Preto, Estado de São Paulo, Brasil

Leptospirosis may affect all domestic and wild animals as well as human beings. Some serological studies have shown the involvement of wild species in the epidemiology of the disease. Once captive wild animals are not much studied, especially in Brazil, the present study aimed to detect anti- Leptospira spp. antibodies in animals from Ribeirão Preto city zoo, in São Paulo state, Brazil. Blood samples were collected from captive birds, fish, reptiles and mammals, sinanthropics and free-living animals and also from employees between March and October, 2006. Four hundred and three blood samples were obtained, 388 animals' samples (110 reptiles, 143 birds, 110 mammals and 25 fish) and 15 humans'. The sera were analysed by Microscopic Agglutination Test using 22 serovars from pathological leptospiras and two from non-pathological serovars. Among the animal samples, 339 were from captive animals, and 49 from free-living ones, captured with traps inside the zoo. One hundred and three (103/388 = 26.5%) samples reacted to leptospirosis, ninety-two (92/339 = 27.1%) samples were from captive animals and eleven (11/49 = 22.4%) from free-living ones. All humans' samples were negative. Serological titles varied from 40 to 5.120, with predominance of titles between 40 and 80 and the most frequent serovars were Patoc, Andamana, Canicola, Icterohaemorrhagiae and Panama.

Avaliação crítica da legislação brasileira de sucos de fruta, com ênfase no suco de fruta pronto para beber

The aim of this work was to critically assess the Brazilian regulations on fruit juices, with emphasis on ready-to-drink fruit juice. According to the Brazilian regulations, bottled fruit juices must follow specific regulations. They should be in accordance with the definition and designation that identify them, with the quality parameters established, and especially, follow the Brazilian food labeling regulations. The Brazilian regulations on bottled fruit juices have some gaps that promote their misunderstanding and marketing of substandard juices. Frequent changes, divergent labeling regulations and inappropriate use of expressions on the label can also lead to misinterpretation. Food regulations need to be clear and updated frequently if they are to be known and followed. Additionally, their wide dissemination should contribute to informed choices when buying.

Ultrassonografia torácica extracardíaca em pequenos animais

Until recently, ultrasonography was not considered one of the prevailing imaging methods for thoracic evaluation due to its limitations in evaluating lesions located below thoracic gas collections in individuals with normal lung tissue as well as in those with pneumothorax. Nevertheless, ultrasound has an advantage over other imaging techniques. It allows not only differentiating pleural from pulmonary lesions, but also identifying and assessing peripheral pulmonary lesions. Thus, thoracic ultrasound has become more popular in Veterinary Medicine as an ancillary method in the diagnosis and treatment of several diseases of the thoracic cavity, especially in emergency settings. This review aims at providing information on the main alterations found in the chest wall, mediastinum, pleura, lung and diaphragm by means of ultrasonography.

N-acetilcisteína - Ação antioxidante e utilização na clínica de pequenos animais

For a long time, N-acetylcysteine was only used as a mucolytic and as an expectorant agent in the treatment of paracetamol/ acetaminophen intoxication. With the advent of studies on free radicals, antioxidants are gaining prominence and the N-acetylcysteine is amongst them. The objective of this article is to emphazise the farmacological activity of this amino acid in affections in the small animal clinical routine, as well as to show new perspectives of its use in humans, which could, in the future, form the base for similar studies in dogs and cats.

A qualidade ambiental urbana na legislação municipal: exemplo do plano diretor de araçatuba-SP 1

Environmental quality is a fundamental issue in order to characterize quality of life in the cities. The human activities interfere in environmental processes, causing impacts that must be minimized. It is the task of municipal laws to impose theoretic and practical foundations appropriated to the dimension of local problems. In this sense, the goal of this work was to propose a discussion about the recognition of environmental quality in municipal law, especially in the Municipal Master Plan of Araçatuba, city located in the state of São Paulo. It was possible to observe that in many aspects this law is far away from urban reality.

Estudo da segurança de cosméticos: Presente e futuro

Cosmetics have been used since ancient times and, recently, their consumption has increased greatly in many countries, including brazil, which is the third largest consumer market in the world. Thus, concern for the safety and efficacy of these products should be heightened, even though these products are rarely related to adverse reactions that damage the health. Brazilian law requires manufacturers to subject their products to safety testing, to assess the possible reactions that could be caused by them (irritation, sensitization, systemic effects). To this end, in general, animals have been used as the experimental model, but this practice is being increasingly controlled, so that the scientific community is looking for alternative tests that do not require experimental in vivo models. Thus, this review aims to describe the main biological assays used to assess the safety of cosmetics, as well as in vitro assays that can replace them.

Dermatologia ambiental: Manifestações dermatológicas de acidentes por animais aquáticos (invertebrados)

Contact between humans and coastal areas has increased in recent decades, which has led to an increase in injuries from aquatic animals. The majority of these present dermatological manifestations, and some of them show typical lesions. The highest percentages of injuries that occur in marine environments are associated with invertebrates such as sea urchins, jellyfish and Portuguese men-of-war (echinoderms and cnidarians). In this review, we discuss the clinical, therapeutic and preventive aspects of injuries caused by marine and freshwater invertebrates, focusing on first aid measures and diagnosis for dermatologists and professionals in coastal areas. © 2013 by Anais Brasileiros de Dermatologia.

Avaliação da liberação de íon fluoreto de cimentos ionoméricos antes e após a recarga e com proteção da superfície

Objective: To evaluate fluoride ion release from two anhydrous glass ionomer cements (GICs) and two resin-modified GICs (RMGICs) before and after recharge with 2% neutral sodium fluoride for 4 min and after surface protection of the Maxxion R GIC with an adhesive system, a cavity varnish and a colorless nail polish. Method: A stainless steel 2x6 mm matrix was used for fabricating 5 specimens of each material, which were immersed in 5 mL of deionized water, renewed every 24 h. Measurements with a potentiometer were performed on days 1, 2, 9 and 17, in the 1st and 2nd phases, and the specimens were buffered with a TISAB III solution. In the 2nd phase, the specimens were subjected to recharge and immersed again in 5 mL of deionized water. In the 3rd phase, the GIC surfaces were protected and readings were made at 5 min, 24 h, 48 h and 72 h. Tukey's post-hoc and Student's t tests were used for statistical analyses (p<0.05). Results: There was statistically significant difference in the comparison between the 1st and 2nd phases for all materials, except at day 2 for Vidrion R and VitroFil LC. In the 3rd phase, it was observed that for all materials, comparison of the first 5 min with the other times revealed statistically significant differences among the means of fluoride ion release. In the comparison with the other times, both the varnish and the colorless nail polish presented statistically significant difference between 24 and 48 h as well as between 24 and 72 h. Conclusion: The anhydrous GICs were more effective in fluoride ion release and recharge compared with the RMGICs. Maxxion R presented a homogeneous and statistically significant behavior in both phases. All materials for surface protection were efficient and the colorless nail polish had the best behavior.

Rendimento e qualidade de melancia cultivada sob proteção de agrotêxtil combinado com mulching plástico

The ground cover is an agricultural practice that is designed mainly to control weeds, while the nonwoven prevents the attack of pests. The objective of this study was to evaluate the yield and fruit quality of watermelon grown under nonwoven textile protection combined with plastic mulching. The experiment was conducted at the WG Fruits Company, Baraúna, RN. A randomized block design was used in a factorial 3 x 3 + 1 with four replications, and 36 plants per plot, with the first factor of color of plastic used in mulching (black, silver and white) and the second factor nonwoven textile with different times of use (first and third crop nonwoven under textile and without nonwoven) and an absolute control (no mulching and without nonwoven). The production variables evaluated were: yield (commercial, noncommercial, and total fruit yield), and fruit quality (soluble solids - SS, titratable acidity - TA and SS/TA). The use of mulching and protection of plants with nonwoven textile provided a higher yield of watermelon fruits in relation to bare soil with and without nonwoven textile protection. Fruit quality was not affected by the use of mulching and nonwoven.
