Abstract: the toxicological sensitivity and specificity of the micro-complement fixation test (mcf) for the detection of botulinum toxins c and d were studied in supernatants of the bacterial cultures and in livers of mice inoculated with lethal and sublethal doses. botulinum toxins c and d were produced in hemoline culture medium, titered through the determination of ld50 by the mouse test and adjusted to dilutions of 10, 1, 0.1, 0.01 and 0.001 ld50. two experimental models were used to determine the toxicological sensitivity of mcf in the supernatant of the culture medium with the dilutions described, and also in liver extracts of mice weighing 20 g and inoculated with the same dilutions. detection of the botulinum toxins was attempted in liver extracts of mice which had received lethal doses of the respective toxins, and in others which had been inoculated with sublethal doses and were sacrificed in intervals of 5 days. the results show that the toxicological sensitivity of mcf, regarding the two types of toxins at the level of 0.001 ld50, was 100% when the supernatants of the culture medium were tested; this means that the sensitivity was 100 times higher than with the mouse test. the toxicological sensitivity of mcf in the liver extracts of mice inoculated with 1 and 10 ld50 of botulinum toxins c and d was inferior, giving values of 100, 80, 89 and 72% respectively. by this test it was also possible to detect botulinum toxins type c and d in liver extracts of mice inoculated with sublethal doses, up to 15 days after the injection. the specificity of mcf was 88% and 92%, when liver extracts of healthy control mice were tested and when challenged with antitoxins c and d; and 100% when challenged with the supernatant of the culture medium. these results indicate that mcf could be of importance for research and could substitute in vivo tests.

Abstract: No presente estudo pretendeu-se verificar a sensibilidade toxicológica e especificidade do Teste de Microfixa o de Complemento (MCF) na detec o de toxinas botulínicas C e D no sobrenadante de cultivos bacterianos e em fígados de camundongos inoculados com doses letais e subletais. As toxinas foram produzidas em meio de cultura Hemoline, tituladas através da determina o da DL50 pelo Bioensaio em Camundongo e diluídas nas concentra es de 10, 1, 0,1, 0,01 e 0,001 DL50. Desta forma, foram utilizadas em dois modelos experimentais, onde foi determinada a sensibilidade toxicológica do MCF no sobrenadante do meio de cultura com as dilui es descritas acima e ainda em extratos hepáticos de camundongos com peso corporal de 20g, inoculados com as mesmas dilui es. A tentativa de evidencia o das toxinas botulínicas nos extratos hepáticos de camundongos foi realizada através da sua extra o após a morte pela administra o das doses letais e ainda pelo sacrifício dos animais inoculados com doses subletais, em intervalos de 5 dias. Os resultados evidenciaram uma sensibilidade toxicológica para o MCF de 100% para os dois tipos de toxinas ao nível de 0,01 DL50, quando testados os sobrenadantes de meio de cultura, portanto 100 vezes superior ao Bioensaio em Camundongo. A sensibilidade toxicológica do MCF, quando examinados extratos hepáticos de camundongos inoculados com 1 e 10 DL50 de toxinas botulínicas C e D, foi inferior, com valores de 100, 80, 89 e 72%, respectivamente. Pelo teste foi possível detectar toxinas botulínicas tipos C e D nos extratos hepáticos de camundongos inoculados com doses subletais até 15 dias após a sua inocula o. A especificidade do MCF foi de 88 e 92%, quando testados extratos hepáticos de camundongos sadios, e confrontados com as antitoxinas C e D; e 100% no sobrenadante do meio de cultura. Os resultados apontam para uma possível utiliza o do teste como importante instrumento de pesquisa e ainda na eventual substitui o dos testes in vivo pelas suas implica es éticas e limita es práticas.

Abstract: Nutrient absorption in crops can decline and their development can be hindered by increased bulk density. This study aimed at assessing the manner in which bulk density levels affect the reproductive structures of the safflower genotypes in the Brazilian Cerrado. The completely randomized design was adopted with four replications for the experiment, which was conducted in a greenhouse using Oxisol collected from 0.0 to 0.2 m depth from the region supporting Cerrado vegetation. The treatments included ten safflower genotypes (PI 237538, PI 248385, PI 250196, PI 301049, PI 305173, PI 305205, PI 306520, PI 306603, PI 560202 and PI 613366) and five bulk density levels (1.0, 1.2, 1.4, 1.6 and 1.8 Mg·m-3). Evaluations were done at 90 days after emergence, in terms of the number, diameter and dry mass of the heads. The data were submitted to the analysis of variance. The means were grouped using the Scott-Knott test at 5% probability. The diameter and dry mass of the chapters were influenced by the mean bulk density of 1.10 Mg·m-3. A notable interaction was evident between the safflower genotypes and bulk density levels for the diameter and dry mass of the head alone, revealing the high degree of genetic variability that environmental changes induce among the genotypes. The PI 250196, PI 301049, PI 305173 and PI 305205 genotypes exhibited greater stability to the bulk density variations compared with the others. Mean bulk density of 1.2 Mg·m-3 was found to impair the development of the reproductive components of the safflower genotypes.

Abstract:

Background: To evaluate hearing outcome, operation time and post-operative hospital stay after primary stapedoplasty with three different techniques: manual microsurgical, microdrill-assisted, and microdrill- and laser-assisted technique. Methods: A retrospective analysis of 150 consecutive cases of primary otosclerosis was operated by one surgeon. The patients were divided into three groups depending on the utilized surgical techniques: a fully manual microsurgical stapedoplasty (n = 56), microdrill-assisted stapedoplasty (n = 32), and microdrill- and laser-assisted stapedoplasty (n = 62). The mean pre- and post-operative air-bone gap was calculated by using pre- and post-operative mean pure tone air- and bone-conduction thresholds at 500, 1000, 2000 and 4000 Hz. Results: There were no statistically significant differences in the hearing outcome between the groups. The closure of air-bone gap and the improvement of the hearing were demonstrated in all study groups. Introduction of diode laser for stapes surgery resulted in significantly reduced operation time (about one-third) and the increase in the

Hadipour, MM;
Revista Brasileira de Ciência Avícola , 2010, DOI: 10.1590/S1516-635X2010000100008
Abstract: since 1998, an epidemic of avian influenza occurred in the iranian poultry industry. the identified agent presented low pathogenicity, and was subtyped as an h9n2 avian influenza virus. backyard chickens can play an important role in the epidemiology of h9n2 avian influenza virus infection. close contact of backyard chickens with migratory birds, especially with aquatic birds, as well as neighboring poultry farms, may pose the risk of transmitting avian influenza virus, but little is known about the disease status of backyard poultry. a h9n2 avian influenza virus seroprevalence survey was carried out in 700 backyard chickens from villages around the caspian sea, northern iran, using the hemagglutination-inhibition (hi) test. the studied backyard chickens had not been previously vaccinated and showed no clinical signs of disease. the mean antibody titers found were 6.8, 7.5, 5.9, 7.2, 5.7, 6.4, 6.2 and the seroprevalence was 76.2%, 79.5%, 68.18%, 78.27%, 65%, 72.31% and 71.4% as found in seven villages. overall hi titer and seroprevalence against h9n2 were 6.52 and 72.98%, respectively.
