ABSTRACT
To survey the occurrence of IgM and IgG anti-T. gondii antibodies in pigs slaughtered without inspection, 110 serum samples from different localities were submitted to indirect hemaglutination test. A frequency of 50.0% (confidence interval 40.7% /.../ 59.3%, 95% significance) of positive sera was detected, with a distribution of frequency of 1.83% and 1.83%, 6.36% and 15.45%, 20.0% and 25.4%, 17.3% and 7.3%, and 4.5% and 0.0% for IgM and IgG antibodies, respectively in 1:16, 1:64, 1:256, 1:1024, and 1:2048 serum dilutions. The toxoplasmic infection was present among pigs in the city of Belém.

Um, vacina experimental contra a doença de Aujeszky (DA), inativada e adsorvida em adjuvante oleoso, foi testada em relaçäo á induçäo de imunidade, grau de proteçäo clínica e capacidade de reduzir a infecçäo, após desafio pela via intranasal. Grupos de 6 suínos, com 45 dias de idade, foram vacinados com uma ou duas doses de vacina, pelas vias intramuscular ou subcutânea, sendo mantido um grupo-testemunha, sem vacinaçäo. Todos os suínos vacinados apresentaram títulos de anticorpos neutralizantes, detectáveis através da prova de soroneutralizaçäo, sendo estatisticamente superiores nos animais que receberam duas doses de vacina. A vacinaçäo preveniu as manifestaçöes clínicas da doença após desafio, principalmente nos animais que receberam duas doses de vacina quando comparado com os que receberam 1 dose. Em todos os animais, vacinados e näo-vacinados, foi possível a detecçäo do vírus da doença de Aujeszky (VDA) nas amígdalas, através da técnica de imunofluorescência direta. A porcentagem de amígdalas positivas nos suínos vacinados com duas doses foi inferior quando comparada àquela de suínos näo-vacinados, no 2º e 7º dias pós-infecçäo. Em suínos vacinados com duas doses de vacina, pela via subcutânea, a taxa de infecçäo foi estatisticamente menor que naqueles vacinados com uma dose, pelas vias intramuscular ou subcutênea, e näo-vacinadas

Since the original description of the most severe from of breast asymmetry by Poland [1], this matter has been revised from time to time. Not all breast asymmetries can be classified as pathologic. Indeed, most women have slightly different breasts. The therapeutic arsenal of modern Plastic Surgery includes techniques of reduction mammaplasty, augmentation mammaplasty and mastopexy, that should be used in accordance with the specific need of each case [2]. In the present study four cases of breast asymmetry are reported, analyzing esthetic aspects and surgical procedures employed in each case.

This study analyzed the perfusion of randomized skin flaps in rats after nicotine injections, in doses that could be compared with heavy and light smorkers. A skin flap was elevated after 12 weeks of nicotine adminsitration and the percentage of necrotic area was determined thereafter. There was a statistically significant difference between "heavy smokers" in the preoperative (G3) and preoperative and postoperative periods (G5), suggesting a deleterious effect of nicotine in the postoperative period
