Trichomonas vaginalis is the flagellate that causes trichomonadiasis, a sexually transmitted disease. Immunological methods have been proposed for the study of antigenic characterization using strains isolated from different patients. This work compares protease profiles from the different strains using gelatin containing polyacrylamide gels to analyse the protease activity. High molecular weight proteases (20 to 100 kDa) were found on gels showing quantitative differences. Human IgG antiproteases were detected by immunoblotting using the same extracts. These proteases could be related with T. vaginalis pathogenesis.

Milk can be an important spreading vehicle of pathogenic agents mainly for young children who are an important group of milk consumers. 135 milk samples (77 of raw milk and 58 of pasteurized milk) were analysed in order to verify the number of heterotrophic bacteria, of Staphylococcus aureus and of total coliforms, as well as to determine presence of Salmonella, Shigella, enteropathogenic Escherichia coli (EPEC) and enteroinvasive Escherichia coli (EIEC). The results were negative for Salmonella, Shigella and EIEC. EPEC serotypes 0:28, 0:111 and 0:55 were isolated in 4 of raw milk samples. The heterotrophic bacteria was found in counts over 30.000 UFC/mL in 91%, 25% and 68,75% respectively of raw milk, milk grade B and grade C. Counts over 30.000 coliforms/mL were found in 70,13%, 6,25% and 6,24% of the raw milk, B and C, respectively. 32,40% of the raw milk had counts of S. aureus over 3.000 UFC/mL.

Planning control programs, for diseases such as rabies requires information on the size and structure of the dog and cat population. In order to evaluate the dog population of the urban area of Araçatuba city, S. Paulo State, Brazil, a survey was conducted using a questionnaire to interview members of households. Eighty-eight districts were visited (37,778 houses) and the interview was possible at 77.93% of these. Human population size evaluated was 113,157 inhabitants. Houses that owned animals represented 55.2%, 26,926 of the animals concerned were dogs and 5,755 were cats. Of the dogs, 56.64% were 1-4 year olds and males represented 56.2% of the total population. Dog: person ratio was estimated at 2.8 dogs to every 10 persons, almost 3 times the ratio hitherto estimated and used in the planning of rabies vaccination campaigns.

A historical chronology of smallpox vaccination in Brazil is presented, with emphasis on the State of Sao Paulo. We also present the scientific and philosophical concepts that influenced the regulation and practice of vaccination in Sao Paulo based on the historiographic bibliography, legislation about vaccination, and the debates in the state legislative body. Discovered by Jenner in 1796, the vaccine reached in Brazil in 1804 and was only used in the colonial capital, the city of Rio de Janeiro. In the 1890 decade, smallpox, side by side with yellow fever, typhoid fever and other pestilential diseases, was the major health problem in the State of Sao Paulo. There was also the fear that the vaccine might transmit syphilis, an Unfounded attitude since the product used in Sao Paulo (the 'animal vaccine') was elaborated from bovine serum. The immediate necessity to fight a highly lethal disease that threatened the State population and the coffee-growing business led to the abandonment of the fears and of the liberal principles in favor of the sanitary needs. The vaccine became compulsory in 1891 in the State of Sao Paulo and its application met no resistance on the part of the population, in contrast to the so-called 'Vaccine Revolt' that would occur in Rio de Janeiro in 1904.

The injuries caused by venomous and poisonous aquatic animals may provoke important morbidity in the victim. The cnidarians (jellyfishes, especially cubomedusas and Portuguese-Man-of-War) caused nearly 25% of 236 accidents by marine animals, while sea urchins were responsible for about 50% and catfish, stingrays and scorpionfish nearly 25%). In freshwater, stingrays and catfish cause injuries with a very similar mechanism to the poisoning and the effects of the toxins of marine species. In a series of about 200 injuries observed among freshwater fishermen, nearly 40% were caused by freshwater catfish, 5% freshwater stingrays and 55% by traumatogenic fish, such as piranhas and trairas. The author presents the aquatic animals that cause injuries to humans in Brazil, the clinical aspects of the envenoming and the first measures for the control of the severe pain observed mainly in the accidents caused by cnidarians and venomous fishes.

This study was accomplished with the objective of knowing the seasonal distribution of the main species of parasites causes of branchial damages to the fish from fee-fishing at Guariba, State of São Paulo. This city is situated at 21 degrees 15'22'' S, 48 degrees 18'58'' W, in altitude 595 meters. This research was conducted between April, 1997 to March, 1999. From 408 fishes examined, 29.1% of them were infested by the protozoans e metazoans. Leporinus macrocephalus showed the highest parasitism by Trichodina sp., although Piaractus mesopotamicus and Cyprinus carpio were also parasited. Piscinoodinium pillulare infestation were found in L. macrocephalus, P. mesopotamicus, C. carpio e Colossoma macropomum. Monogenetics metazoan have largely been observed in L. macrocephalus, P. mesopotamicus, C. carpio, C. macropomum e cross-bred tambacu. The incidence of this parasite was elevated in the summer for L. macrocephalus, spring for P. mesopotamicus and C. macropomum, and both seasons for cross-bred tambacu. Lernaea cyprinacea copepodes were observed in L. macrocephalus, P. mesopotamicus, C. carpio and cross- breeding tambacu, in spite of the fact that C. carpio has demonstrated high parasitism of adult form. The fish L. macrocephalus, P. mesopotamicus and C. carpio were sponged intensely by Dolops carvalhoi, in situation of high population density. Piaractus mesopotamicus was considered the species more parasited by myxosporídeos, that were also observed in L. macrocephalus and cross-breeding tambacu.

Objective: To verify the prevalence of overweight and obesity in 7 to 10 year old schoolchildren of both sexes and high socioeconomic level. Methods: Five hundred and eleven schoolchildren (274 boys and 237 girls) were submitted to anthropometrical measurements of body mass, stature and subscapular and triceps skin-fold thickness. Body mass indexes ≥85th percentile and <95th percentile were used to determine overweight, whereas body mass indexes ≥95th percentile were adopted as indicators of obesity. The socioeconomic level was established based on information obtained from a questionnaire, considering the degree of education of the parents and the familiar consumables. Results: The total prevalence for overweight was 19.7% for the boys and 17.3% for the girls, with no significant differences amongst ages and sexes (p>0.05). On the other hand, the prevalence for obesity in the boys and girls was 17.5% and 9.3%, respectively, with significant differences between the sexes at 9 years (p<0.01) and 10 years (p<0.05) of age, as well as amongst the entire group of ages (p<0.01). Conclusion: The results indicated a high prevalence ratio for overweight (∼19%) and obesity (∼14%), much greater than the average for the 7-10 year old Brazilian population. Therefore, different from that observed in developed countries, a high socioeconomic level seems to negatively affect the prevalence for overweight and obesity, increasing the risk of the precocious development of metabolic dysfunctions.

Phytotherapy is a form of familiar treatment throughout the world and recommended by the World Health Organisation to be used in all regions, especially in the poorer countries, to improve the state of health of their people. The aim of this study was to describe the use of herbal medicine as an alternative therapy in the public health system in Sao Paulo State. The fieldwork consisted in obtaining information, from all the Regional Health Authorities in the State, about which municipal health areas use this therapy and sending them a questionnaire requesting details about the application of phitotherapy: when the therapy had been adopted, which plants were used, whether the programme had been discontinued or not and if so, for what reason. The cities that use the phytotherapy are: Campinas; Canas; Guaratingueta; Herculandia; Piquete; Pindamonhangaba; Roseira e Sao Jose do Barreiro, Ribeirao Preto, Sao Lourenço da Serra, Cruzeiro e Dobrada. And the three plant more used are: Guaco (Mikania glomerate); Calendula (Calendula officinalis) e Babosa (Aloe vera) The lack of support has led some Authorities to discontinue their active in 08 programmes. Nevertheless, it is concluded that the efficacy and low cost of herbal treatments has engendered a growing interest among health professionals in placing proposals for implanting this therapy in 13 cities in the Municipal Health. Thus, there should be growing practical support for the establishment of such programmes in the future.

This work evaluates the impact of the pink shrimp Farfantepenaeus paulensis (Perez-Farfante, 1967) fishery on fish and crab assemblages of Lagoa do Peixe National Park, Brazil. We observed that composition of catches is similar to shrimp fisheries using fyke-net at others estuaries of Rio Grande do Sul State: pink shrimp (53%), accessory catches (24%) and bycatch (23%). However, fishery composition showed distinct differences along the saline gradient of the main park's lagoon. Regarding only fish species, the most impacted species in this fishery were Brevoortia pectinata (Jenyns, 1842), Micropogonias furnieri (Desmarest, 1823), and Jenynsia multidentata (Jenyns, 1842). In others estuaries from Rio Grande do Sul, in contrast, the most impacted species were M. furnieri, Genidens barbus (Lacepède, 1803) and Genidens genidens (Cuvier, 1829). The potential impact of the pink shrimp fishery at Lagoa do Peixe National Park seemed to be weaker when compared to shrimp fisheries elsewhere. We believe that the decision to prohibit this fishery at the Lagoa do Peixe National Park should not be based on its potential damage to the fish and crab assemblages but based on the simple fact that Brazilian laws do not allow fisheries inside National Parks.

Objective: To evaluate the occlusal condition of children with 5 years of age examined by the Brazil Oral Health 2003 Project in Cáceres city, Brazil. Material and Methods: The sample consisted of 170 preschool children raffled from 20 schools participant of the project. For the analysis of the occlusal it was used the 1987' World Health Organization index, modified by the Public Health School of São Paulo University, Brazil, in 1996, which establish criteria according to severity of malocclusion. Results: It was observed that 65.3 % of children presented normal occlusion, 31.18 % presented light occlusal problems and 2.35 % showed moderate/severe. Conclusion: Due to the large presence of malocclusion, it is necessary this kind of survey, so that the city can plan and perform preventive orthodontic treatments, besides other preventive proceeding, to obtain a proper oral environment for the normal evolution of occlusion. © 2008 1995, Editorial Ciencias médicas.

The present study applies a method of prevalence analysis to data obtained in two nationwide household surveys on alcohol use during life and dependence, for each of the sexes. The ratios of prevalences (R), for the lifetime alcohol use and dependence rates, between the two genders in the various Brazilian macro-regions, were calculated together with their respective 95% confidence intervals. It was found that lifetime use, both in 2001 and in 2005, was significantly greater in Brazilian males in all geographical regions. In 2001, the population of the North (male and female) had a higher rate of alcohol consumption than that in the Brazilian population as a whole and that in the Southeast. Dependence on the consumption of alcoholic drinks in 2001 and in 2005 was greater in the male sex, but similar among the various regions studied. It can be concluded that this method of analyzing the data on alcoholism could be of great use in assessing its magnitude and importance in terms of public health.

Distribution and ecology knowledge of sandfly species is essential for epidemiology vigilance and risk determination for transmission of leishmaniasis. Sandfly trapping was carried out in a cerrado strictu sensu vegetation fragment in a rural area of Corumbataí Municipality, São Paulo State, Brazil, during July to November 2004. Two CDC light traps were used from 18h to 8h, once a month, resulting in 112 total hours of capture. During this period, 60 sandfly specimens of ten different species were sampled. The most abundant species and the one found in all captures was Pintomyia monticola totalizing 15 (25.0%) specimens, the second more abundant one was P. pessoai with 14 (23.3%) and the third one was Brumptomyia guimaraesi with 12 (20.0%) individuals collected. Other captured species were Psathyromyia aragaoi, B. avellari, B. brumpti, B. cunhai, P. bianchigalatiae, Evandromyia termitophila and Nyssomyia whitmani which corresponded to 19 (31.2%) specimens captured. Pintomyia pessoai and N. whitmani presence indicates transmission risk of American Cutaneous Leishmaniasis in the area.
