13. Effect of salbutamol on pulmonary responsiveness in chronic pulmonary allergic inflammation in guinea pigs
Beta-2-agonists have been widely used by asthmatic subjects to relieve their obstructive symptoms. However, there are reports that continuous use could lead to loss of bronchial protection and exacerbation of asthma symptoms. We evaluated the effect of two regimens of salbutamol administration (twice and five times a week) in a model of chronic airway inflam

14. THE REAR CAR SEAT SAFETY BELT: AN ERGONOMIC APPROACH / CINTO DE SEGURANÇA DO BANCO TRASEIRO DO AUTOMÓVEL: UMA ABORDAGEM ERGONÔMICA
This study is developed based on the hypothesis that the deficiencies of project of the package for the automobile`s rear passengers, as well as of the rear seat safety-belt itself, from the ergonomic point of view, cause discomfort and constrain people to its usual use. Therefore, its rejection or misuse have been subjecting the passengers to injuries and e

15. Naturalism and biological conception of cities in the constitution of the idea of urban environment / Naturalismo e biologização das cidades na constituição da idéia de meio ambiente urbano
In this dissertation the formulation of a concept of urban environment is based on the perspective of ideas which have historically attempted to understand cites in biological terms, such as body, organism or more recently eco-system. This tendency to naturalize or conceive cities in biological terms has been a characteristic of social th

16. Vida sufocada : sofrimentos de pessoas com pneumopatias crônicas e a promoção da saúde pelo autocuidado
Although the bimedical sample focus the lack of air and cronicity, it is possible to understand the illness defended by Kleinman (1988) of the Chronic Obstructive Lung Disease (COPD) in how the persons realizes, cohabits and proceeds with the symptons. The aims of this research were discover the Explanatory Model (EM) of patients, caretakers and health profe

17. Production of monoclonal antibody to subtype 9 of Neisseria meningitidis and the distribution of this subtype in Brazil
A new monoclonal antibody (5F81A4P1.9), which is specific for subtype 9 antigen of meningococci, was studied. The antibodies were raised against a previously non-typable (NT) serogroup B strain from Brazilian patients and were found to react with the subtype antigen of prototype reference strains for subtype 9 (M982), as well as with those of homologous stra

18. Infectious bursal disease virus: case report and experimental studies in vaccinated and unvaccinated SPF chickens and commercial broiler chicks
IBDV Gm 11 (Simbios eleven-molecular group) has been detected since 1997 in many farms of commercial broilers and layers causing high mortality (2 to 15%) and severe macro and microscopic damage in cloacal bursae, spleen, thymus, kidney and liver. Five serial passages of 2050/97-Gm 11 IBDV sample by CAM route in SPF chicken's embryonated eggs did not elicit

19. Monitoring activities in hosts prepared to be compromised (Honeypots) / Monitoração de atividades em máquinas preparadas para serem comprometidas (Honeypots)
Not long ago, information systems security was closely associated with passive protection, always assuming a purely defensive stance. Nowadays, this approach is changing. Reactive measures are helping to improve systems security, with the use of hosts prepared to be compromised (honeypots) providing information about the techniques used by the attackers, fro

20. Estudo comparativo entre solução cardioplegica cristaloide e microcardioplegia sanguinea normotermica em corações agudamente isquemico
Objective: There are several methods of myocardial protection. Blood solutions modified with glutamate and aspartate are increasingly being used and in the case of acute ischemia, they enhance the contractile function resuscitating the injured musc1e. The dilution recommended in the literature is approximately 25% of the hematocrit. This present study evalua

21. AnÃlise tÃrmica de vigas mistas aÃo-concreto em situaÃÃo de incÃndio / Thermal analysis of composite steel-concrete beams in fire situation
A estabilidade estrutural dos edifÃcios em situaÃÃo de incÃndio à diretamente dependente da resistÃncia mecÃnica de seus elementos estruturais que, por sua vez, dependem da temperatura que estarÃo sujeitos durante o incÃndio. Os elementos estruturais quando expostos aos gases quentes do incÃndio perdem resistÃncia e rigidez devido à degeneraÃÃo

22. Glycolipoprotein from Pseudomonas aeruginosa as a protective antigen against P. aeruginosa infection in mice.
After primary subcutaneous immunization of rabbits with glycolipoprotein from Pseudomonas aeruginosa BI, indirect hemagglutinating and bacterial agglutinating activities appeared in the antiserum 6 days after immunization and reached a peak between 15 and 20 days. Both these in vitro activities paralleled in vivo antipseudomonas-induced leukopenia and mouse

23. Passive Immunization Against Experimental Pseudomonas Infection: Correlation of Protection to Verder and Evans “O” Serotypes
Passive-protection tests were conducted in mice with antisera from rabbits immunized with formalinized or heat-killed cells or with an alcohol-precipitated fraction from the slime layer. Protection was conferred by antisera against the heatstable antigens and correlated well with agglutinin levels. Specificity was found to relate closely to the heat-stable �

24. Mouse-protective Properties of Bordetella pertussis Serotypes in Passive Tests
In a passive protection procedure in which the ed50 values of Bordetella pertussis antisera were determined, groups of mice were given graded intraperitoneal doses of serum, followed the next day by intracerebral challenge with 100,000 organisms. Antiserum produced with B. pertussis culture 5373, serotype 1.3, protected mice against challenge with culture 18
