Prevalence of enamel white spots and risk factors in children up to 36 months old

The aim of this study was to determine the prevalence of enamel white spots and the quality of oral hygiene in children up to 36 months old, in municipalities with different fluoride levels in the water supply, analyzing the contribution of several variables. After approval of the Ethics Committee, the parents signed an informed consent form and were interviewed about their educational level, economic classification of the family, nursing habits, use of toothpaste, access to dental service and other information. The children were clinically examined using the same codes and criteria established by the WHO (World Health Organization) and ADA (American Dental Association). The data were processed and analyzed with the Epi-info software program, version 3.2, and Microsoft Excel. Fisher's exact test (p<0.05) was applied to assess the association among the variables. The enamel white spot prevalence was 30.8% and the age group, duration of the bedtime milk feeding habit, age of initial practice of oral hygiene and presence of caries lesions with cavitation were considered statistically significant with regard to enamel white spot prevalence (p < 0.05). No association was found between oral hygiene quality and the study variables. © 2009 Sociedade Brasileira de Pesquisa Odontológica.

Avaliação morfométrica dos hepatócitos de ratos diabéticos tratados com neem (azadirachta indica a. juss) e estreptozootocina 6 ch

The effects of extracts from Azadirachta indica A. Juss and streptozotocin, in extreme high dilutions in dinamized systems, on hepatocyte morphometry of rats with diabetes mellitus induced by streptozotocin were evaluated. Some parameters presented significant differences among the experimental groups, but the effect of treatments to make better or worse the consequences of diabetes mellitus on liver was not detected using only the hepatocyte morphometry. The morphometric analysis evidenced that the white control group presented the highest mean values for nucleus and cytoplasm parameters, with the exception of the nuclear shape factor. However, this situation did not imply the diabetes mellitus was the cause of drastic reduction in these values, since the literature describes lower measurements for rats from the control group (non-diabetic rats).

Estudo filogenético de populações de Ceratobasidium noxium, agente causal do mal-do-fio do caqui (Diospyrus kaki) e do chá (Camellia sinensis) no Estado de São Paulo, patogenicidade cruzada e reação de variedades de caqui ao patógeno

Flavonóides de Cissus verticillata e a atividade hipoglicemiante do chá de suas folhas

Cissus verticillata, a Vitaceae very used in the traditional medicine in Pará and Minas Gerais State – Brazil, was investigated in order to validate its indication for the hyperglycaemia control. The aqueous extract reduces the normal glycaemia of male white Wistar rats in about 19.5 %. The hypoglycaemic effect of this extract could be related to the flavonoids found in the preparation. Luteolin, Kaempferol and Luteolin-3'-sulphate could be isolated from the aqueous extract after acid hydrolysis. Cissus
