Abstract: Essential oils are secondary metabolites whose biological properties have been studied with emphasis on antimicrobial activity. Hyptis carpinifolia Benth (Rosmaninho) is used in folk medicine in the fight against colds and rheumatism. The objective of this study was to evaluate the antimicrobial activity of the essential oil from H. carpinifolia. The essential oil was extracted by hydrodistillation using a modified Clevenger apparatus. The biological activity was determined using the Agar Cavity Diffusion technique to evaluate the effect of concentrations of 500, 250, 125, 62.5, 31.25, 15.62, 7.81 and 3.9 μg·mL-1 on the bacteria Escherichia coli, Listeria monocytogenes, Salmonella Choleraesuis, Staphylococcus aureus and Pseudomonas aeruginosa. The fungicidal potential was evaluated by the method of dilution in agar, and the percentage inhibition of mycelial growth of Alternaria alternata, Botrytis cinerea and Fusarium oxysporum was evaluated. The dilutions tested were 1000, 750, 500, 250 and 100 μL·L-1. The minimum inhibitory concentrations (MIC) of the essential oil for L. monocytogenes, S. aureus and E. coli were 31.25;

Abstract: context and objective: studies using radionuclides are the most appropriate method for estimating renal function. dimercaptosuccinic acid chelate labeled with technetium-99m (99mtc-dmsa) is the radiopharmaceutical of choice for high-resolution imaging of the renal cortex and estimation of the functional renal mass. the aim of this study was to evaluate a simplified method for determining the absolute renal uptake (aru) of 99mtc-dmsa prior to nephrectomy, using the radioactivity counts of nephrectomy specimens as the gold standard. design and setting: prospective study at the division of nuclear medicine, department of radiology, universidade estadual de campinas. methods: seventeen patients (12 females; range 22-82 years old; mean age 50.8 years old) underwent nephrectomy for various reasons. renal scintigraphy was performed three to four hours after intravenous administration of a mean dose of 188.7 mbq (5.1 mci) of 99mtc-dmsa, which was done six to 24 hours before surgery. the in vivo renal uptake of 99mtc-dmsa was determined using the radioactivity of the syringe before the injection (measured using a dose calibrator) and the images of the syringe and kidneys, obtained from a scintillation camera. after surgery, the reference value for renal uptake of 99mtc-dmsa was determined by measuring the radioactivity of the nephrectomy specimen using the same dose calibrator. results: the aru measurements were very similar to those obtained using the reference method, as determined by linear regression (r-squared = 0.96). conclusion: aru estimation using the proposed method before nephrectomy seems to be accurate and feasible for routine use.

Ciência & Saúde Coletiva , 2007, DOI: 10.1590/S1413-81232007000200019
Abstract: the author has the intention to propose to the brazilian health care management and sanitary reform managers an examination and positioning on the course of action in the implementation of sus (brazilian national health system). the findings underscore two non-convergent set of policies that have affected the course of action in the implementation of the sus in the 1990s: the first and 'main' course of action derives from policies created in 1988 in the so-called citizen constitution, of which the sus is the most important achievement. the second and "additional" course of action derives from the prevailing macro-economic model and its related policies, implemented since the 1990s, besides advocating a social inclusion measure while leaving out all the related improvements of sus such as universality, integrity and equity. in addition, the second course of action is in opposition to the model based on social protection, besides raising the importance of market-based individualistic values and actions in general, it carries them into the health care system. the author suggests that a clarification on the desirable and on the deviant courses of action of sus may be a vital contribution to guaranteeing social rights in health care, while preserving its integrity, equity and universal nature.

Santos,Nelson Rodrigues dos;
Ciência & Saúde Coletiva , 2008, DOI: 10.1590/S1413-81232008000900002
Abstract: besides recognizing the irreversible advances made in the brazilian health system, the author unveils the crossroad by identifying questions still pending over the more than seventeen years of the organic law on health - in the management models of the system and of the services, in the healthcare models, in the democratic participation. scenarios of the current situation are evaluated, the pact in favor of life, the brazilian health system, the ec-29 regulation (amendment to the constitution) and the plan for growth acceleration in health and its intersections. the author points to some solutions and finally refers to three successive conjunctures - the 80s, the 90s and the present decade - aiming to contribute to the search and choice of directions. this text passed through previous versions that received important corrections and improvements.

Abstract:

In this study a modified Kokubo’s treatment (MKT) was used to bioactivate titanium implants. Titanium surfaces were alumina-blasted and etched in HCl/H2SO4 solution followed by treatment in autoclave at 120°C for 1, 3, 5 hour periods with chemical solutions containing 1, 2 and 3 M of NaOH. The materials were characterized by surface angle measurements, roughness, field emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), and in vivo tests. Statistical analysis by polynomial regression showed that solutions within 2.2 and 2.8 M NaOH lead to surface contact angles close to zero degree after 1 h of treatment. XPS analysis carried out on a sample treated 1 h in 2.2 M NaOH indicated the presence of a titanate film. This solution was selected to treat titanium implants for in vivo tests. These tests were performed on sheep in three types of separating surfaces: machined group (standard), SLA group (A) and MKT group (B) divided into two time intervals of 3 and 6 weeks. The samples in group B displayed better results compared to group A only after 6 weeks in terms of counter torque and bone implant contact (BIC).
