Estudo da pressão arterial pelo método indireto oscilométrico (petmap®) em cães domésticos não anestesiados

O estudo das pressões arteriais sistólica, média, diastólica e da frequência cardíaca, pelo método indireto oscilométrico (petmap®), foi realizado em 150 cães atendidos pelo Serviço de Clínica Médica de Pequenos Animais da FMVZ - Unesp/Botucatu. Investigou-se a influência de fatores como presença do proprietário, estado de saúde, diagnóstico de doença renal, raça, idade, sexo, decúbito, contenção, fluidoterapia, condição corpórea, temperamento, atividade física, dieta e atitude associados ou não à elevação da pressão arterial. Dos 150 cães, 34% encontravam-se sob a categoria de risco mínimo para o desenvolvimento de lesões hipertensivas, 14,6% com hipertensão branda, 22,6% com hipertensão moderada e 28,66%, com hipertensão grave. Houve influência, dos fatores analisados, na elevação da pressão arterial de acordo com a categoria de risco.

Surface electromyography of facial muscles during natural and artificial feeding of infants

Objective: To measure and compare the activity of the masseter, temporalis and buccinator muscles in different infant feeding methods. Method: Cross-sectional study of 60 full-term infants with no intercurrent diseases, aged between two and three months, classified into the following groups: 1) exclusive breastfeeding; 2) breastfeeding plus bottle-feeding; and 3) exclusive breastfeeding plus cup feeding. Surface electromyography was performed during infant feeding. The Krushal-Wallis test was used, complemented by multiple paired comparisons of the groups. A 5% significance level was chosen for the tests. Results: Statistically higher results were verified in the breastfeeding group in relation to the bottle-feeding one, both in the range of movement and the mean contraction of the masseter. With regard to the temporalis muscle, statistically higher results were found in the breastfeeding group comparatively to the bottle-feeding one. As to the buccinator muscle, statistically higher results were observed in the breastfeeding group in relation to the bottle-feeding one, although in this case, the difference concerned only the range of contraction. Conclusion: The similarities between the muscle activity in the breastfeeding and in the cup-feeding groups suggests that cup-feeding can be used as an alternative infant feeding method, being better than bottle-feeding, due to the hyperactivity of the buccinator muscle, which could result in changes to the structural growth and development of the stomatognathic system functions.

Study of the electrochemical behavior of histamine using a Nafion®-copper (II) hexacyanoferrate film-modified electrode

A study on the electrochemical behavior of histamine species in aqueous medium is described. A glassy carbon electrode chemically modified with copper (II) hexacyanoferrate (CuHCFe) film and covered with Nafion® film was employed. The interaction between the analyte and the CuHCFe film can be demonstrated by a decrease in both the cathodic and anodic peak currents at 0.68V (vs. Ag/AgCl), attributed to the film and the appearance of new peak current at 0.47V. Cyclic voltammetric parameters obtained for histamine indicate the formation of stable complex between histamine adsorbed at the electrode surface. The dependence of peak currents on the concentration of the analyte is not linear in the employed work range, indicating the presence of a coupled chemical reaction in the electrodic process. © 2010 by ESG.
