Abstract: Por meio de estudo retrospectivo, descreve-se a casuística referente aos atendimentos prestados a acidentados de transito, em 1988, em hospital de Pronto Socorro de Porto Alegre, RS - Brasil. Os dados utilizados foram fornecidos pelo Setor de Documenta o e Estatística do hospital estudado (n=6.099). Os resultados encontrados, similares àqueles descritos na literatura, chama especial aten o pela predominancia do sexo masculino (69,2% do total de atendimentos), pela concentra o dos acidentados na faixa etária dos 20 aos 39 anos (52%) e pela freqüência com que a cabe a é acometida (49,6% dos pacientes). Les es severas como contus es e fraturas foram encontradas, respectivamente, em 61,5% e 24,2% dos pacientes. Os dados revelam, ainda, o elevado número e a gravidade das les es resultantes de atropelamentos, os quais foram responsáveis por 32,7% do total de atendimentos por acidentes de transito, 57,2% das interna es hospitalares, 54,6% dos atendimentos de menores de 9 anos e 42,8% dos acima de 60 anos.

Abstract: the clearance of long-acting progesterone in microspheres (p4la) in zebu animals and its potential for use in estrus synchronization were evaluated using 30 nelore and 30 crossbreed (holstein x zebu) heifers, with aging between 120 to 150-day-old and weighting 150kg in average. for each breed the animals were divided into three groups of ten animals each, gi= control group treated with saline; gii= treated with 450mg of p4la; and giii= treated with 750mg of long-acting progesterone (p4la). blood samples were colleted on days 0, 7 and 13 and analysed for progesterone using radioimmunoassay in solid phase. the serum concentration of progesterone was different on days 0, 7 and 13 in relation to the dose of p4la given. all treated animals presented basal values for progesterone on day 0, increased on day 7 and decreased on day 13, but with values over 1ng/ml. the results show that the drug was absorbed rapidly after its administration and remained in satisfactory concentration in the circulation until day 13. the average total concentration of serum progesterone was higher in nelore heifers when compared to the concentration in crossbreed ones, indicating difference in the metabolism of the drug between the two genetic groups.

Abstract: ectopic gastric mucosa (egm) is considered to be a congenital condition. rare cases of adenocarcinoma have been described. there are no data justifying regular biopsies or follow-up. cyclooxygenase-2 (cox-2) is a protein involved in gastrointestinal tumor development by inhibiting apoptosis and regulating angiogenesis. the aim of this prospective study was to evaluate cox-2 expression in egm and compare it with normal tissue and barrett's esophagus. we evaluated 1327 patients. biopsies were taken from the inlet patch for histological evaluation and from the gastric antrum to assess helicobacter pylori infection. biopsies taken from normal esophageal, gastric antrum and body mucosa and barrett's esophagus were retrieved from a tissue bank. egm biopsies were evaluated with respect to type of epithelium, presence of h. pylori, and inflammation. cox-2 was detected by immunohistochemistry using the avidin-biotin complex. egm islets were found in 14 patients (1.1%). histological examination revealed fundic type epithelium in 58.3% of cases, h. pylori was present in 50% and chronic inflammation in 66.7%. expression of cox-2 was negative in normal distal esophagus, normal gastric antrum and normal gastric body specimens (10 each). in contrast, egm presented over-expression of cox-2 in 41.7% of cases and barrett's esophagus in 90% of cases (p = 0.04 and 0.03, respectively). cox-2 immunoexpression in egm was not related to gender, age, epithelium type, presence of inflammation or intestinal metaplasia, h. pylori infection, or any endoscopic finding. our results demonstrate up-regulation of cox-2 in egm, suggesting a possible malignant potential of this so-called harmless mucosa.

Abstract: the effects of schistosomiasis on microsomal enzymes were studied on post-infection day 90 when accumulated damage and fibrosis are most intense but granulomatous reaction around the eggs harbored in the liver is smaller than during the earlier phases. swiss webster (sw) and dba/2 mice of either sex (n = 12 per sex per group) were infected with 100 schistosoma mansoni cercariae on postnatal day 10 and killed on post-infection day 90. cytochrome p-450 (cyp) concentration and alkoxyresorufin-o-dealkylases (erod, mrod, brod, and prod), p-nitrophenol-hydroxylase (pnph), coumarin-7-hydroxylase (coh), and udp-glucuronosyltransferase (ugt) activities were measured in hepatic microsomes. age-matched mice of the same sex and strain were used as controls. in s. mansoni-infected mice, cyp1a- and 2b-mediated activities (control = 100%) were reduced in sw (erod: male (m) 36%, female (f) 38%; mrod: m 38%, f 39%; brod: m 46%, f 19%; prod: m 50%, f 28%) and dba/2 mice (erod: m 64%, f 58%; mrod: m 60%; brod: f 49%; prod: m 73%) while pnph (cyp2e1) was decreased in sw (m 31%, f 38%) but not in dba/2 mice. coh did not differ between infected and control dba/2 and ugt, a phase-2 enzyme, was not altered by infection. in conclusion, chronic s. mansoni infection reduced total cyp content and all cyp-mediated activities evaluated in sw mice, including those catalyzed by cyp2e1 (pnph), cyp1a (erod, mrod) and 2b (brod, prod). in dba/2 mice, however, cyp2a5- and 2e1-mediated activities remained unchanged while total cyp content and activities mediated by other cyp isoforms were depressed during chronic schistosomiasis.

Abstract: O objetivo deste trabalho foi o de avaliar o desempenho reprodutivo de 211 porcas da linhagem Camborough 22a , de diferentes ordens de parto, submetidas à infus o transcervical de plasma seminal ou de estrógeno no início do estro. Após o desmame, elas foram examinadas duas vezes ao dia para a detec o do estro, na presen a de um macho sexualmente maduro, e da ovula o, com auxílio da ultra-sonografia transcutanea. No início do estro as fêmeas receberam aleatoriamente uma infus o transcervical de plasma seminal, de estrógeno ou permaneceram como grupo-controle. Todas as fêmeas foram inseminadas no turno seguinte à detec o do estro, recebendo no máximo três insemina es com intervalos de 8 a 16h. No grupo-controle as fêmeas de primeiro parto ovularam mais precocemente que as fêmeas com maior número de partos (P<0,05). Os tratamentos n o influenciaram a dura o do estro e o momento da ovula o. O número total de leit es nascidos n o diferiu entre os tratamentos.

Abstract: observational studies were carried out in four industrial swine farms. the observations were performed on a 24 hours basis and mummified fetuses, stillborn and born alive piglets were recorded by observers (ob) and by employees (em). in all farms, it was also obtained a retrospective data previous to the observational study period, comprising the same number of farrowings. differences among mummified fetuses and total born piglets recorded by ob and em in all farms (p<0.05) were observed. the recorded number of stillborn piglets differed between ob and em in three farms (p<0.05) and the number of born alive piglets in one unit (p<0.05). in all farms during the analysis period, the maximal percentage of recorded mummified fetuses, stillborn, born alive and total born piglets, were 67.8%, 34.5%, 1.8% and 5.1%, respectively. the comparison of retrospective and em data showed a maximal percentage of not recorded mummified fetuses, stillborn, born alive and total born piglets by em of 70.4%, 82.1%, 10.5% e 16.5%, respectively. these errors can induce to a wrong interpretation of the farm data and the efforts to maximize the productivity could be directed to other sectors than the farrowing house.
