Hematological reference values and animal welfare parameters of BALB/C-FMABC (Mus musculus) inoculated with Ehrlich tumor kept in the vivarium at ABC Medical School.

BACKGROUND: Biochemical and hematological parameters are important tools for assessing the physiological profile of vital organs, and can be recorded to create reference values used for clinical diagnosis of diseases. Many research laboratories lack the means to establish their own set of reference parameters for use in their research, and while there are articles in the literature that discuss laboratory parameters for healthy BALB/c mice, few studies address the evaluation of these parameters in pathological situations, such as in mice inoculated with Ehrlich tumor. METHOD: BALB/c-FMABC mice previously inoculated with Ehrlich tumor were maintained under appropriate conditions. Blood samples were taken for analysis of hematological parameters using automated and semi-automated equipment to create a set of the animal welfare parameters for evaluation. RESULT: Results were obtained for all the hematological parameters for all groups analyzed. These showed: statistically significant differences between the initial and final tumor weight; comparable initial tumour volume and weight; an increase in leukocytes in the 7-day group with a characteristic predominance of lymphocytes and neutrophils; statistically significant changes in RDW in the 21-day group and in the welfare parameters in the 28-day group. CONCLUSION: The study successfully defined and established reference values for hematological and welfare parameters for all groups analyzed.

Prevalence of enteroparasitosis in the municipality of São Bernardo do Campo ­ SP / Prevalência das enteroparasitoses no município de São Bernardo do Campo - SP

Objective: The objective of this study was to evaluate the prevalence of enteroparasitosis in stool samples from residents of São Bernardo do Campo ­ SP, who use the public health service through the Basic Health Unit (UBS), defining the most frequent enteroparasites by age. and district with the highest prevalence. Methods: For this retrospective study, 17,018 fecal examinations were performed from June to December 2017. The data came from the Parasitology Laboratory of the Centro Universitário Saúde ABC ­ FMABC, and the prevalence of enteroparasitosis by age and district was analyzed. The project was approved by the Research Ethics Committee of Universidade Paulista ­ UNIP, under nº 2.715.169. Results: The most common protozoan (33.86%) was Giardia spp., followed by Entamoeba histolytica/dispar, most common in young adults aged 18 to 40 years (9.16%). Enterobius vermicularis had a prevalence of 5.58%, being more frequent in children from 0 to 11 years old. In adults (41-65 years) and elderly (> 65 years), the most common helminth found in the samples was Strongyloides stercoralis (18%). Conclusion: It is concluded that Giardia spp. was the most frequent parasite and frequently observed in children (0-11 years), in the elderly was Strongyloides stercoralis. This study serves as a warning about the need to implement efficient public health, focused mainly on the prevention and control of these and other types of diseases.

Objetivo: Este trabalho teve como objetivo avaliar a prevalência de enteroparasitoses em amostras de fezes de moradores de São Bernardo do Campo ­ SP que utilizam o serviço público de saúde por meio da Unidade Básica de Saúde (UBS), definindo as enteroparasitas mais frequentes, por idade e bairro com maior prevalência. Métodos: Para este estudo retrospectivo, foram realizados 17.018 exames fecais no período de junho a dezembro de 2017. Os dados foram provenientes do Laboratório de Parasitologia do Centro Universitário Saúde ABC ­ FMABC, sendo realizada a análise de prevalência das entero­parasitoses por idade e bairro. O projeto foi aprovado pelo Comitê de Ética em Pesquisa da Universidade Paulista ­ UNIP, sob o nº 2.715.169. Resultados: O protozoário mais frequente (33,86%) foi Giardia spp., seguido por Entamoeba histolytica/dispar, mais frequente em adultos jovens de 18 a 40 anos (9,16%). Enterobius vermicularis apresentou uma prevalência de 5,58%, sendo mais frequente em crianças de 0 a 11 anos de idade. Em adultos (41-65 anos) e idosos (> 65 anos), o helminto mais frequente encontrado nas amostras foi o Strongyloides stercoralis (18%). Conclusão: Concluímos que Giardia spp. foi o parasita mais frequente e frequentemente observado em crianças (0 a 11 anos), em idosos foi o Strongyloides stercoralis. Este estudo serve como um alerta sobre a necessidade de se implementar uma saúde pública eficiente, voltada principalmente à prevenção e controle desses e de outros tipos de doenças.
