Avaliação do conhecimento e das condutas dos farmacêuticos, responsáveis técnicos por drogarias

Através deste estudo, avaliou-se o nível de conhecimento e conduta dos farmacêuticos, responsáveis técnicos (RT) em drogarias, quanto a alguns aspectos da legislação farmacêutica e sanitária. Foram entrevistados 45 RT em 2007, sendo que 19 desconheciam a definição dos medicamentos de referência, 21 do genérico e 25 do similar. Todos sabiam da permissão de aplicação de medicamentos injetáveis. Porém, apenas dois sabiam da permissão da aplicação de penicilínicos, metade desconhecia que é permitido fracionar medicamentos fracionáveis em drogaria, 18 não sabiam dispensar corretamente uma prescrição pelo princípio ativo e 37 acreditavam que o farmacêutico pode intercambiar qualquer medicamento de marca pelo genérico. A maioria dos RT apresentou nível regular e insatisfatório de conduta e de conhecimento sobre a legislação profissional e sanitária, o que sinaliza um problema na formação acadêmica e de atualização permanente, podendo comprometer as diretrizes da política nacional de medicamentos.

ABSTRACT Assessment of knowledge and behavior of pharmacists with technical responsibility for drugstores This paper is a study of the level of knowledge and conduct of the legally responsible pharmacist-in-charge (PIC) at drugstores, regarding certain aspects of pharmaceutical and health legislation. In 2007, 45 PICs were interviewed, of whom 19 did not know the definition of original (innovative) branded drugs, 21 of generic drugs and 25 of similar branded drugs. All PICs knew that it is permitted to administer injectable drugs in the drugstore. However, only two knew that penicillins can be injected, half of them did not know that certain medicines can be fractionated in drugstores, 18 did not know how to dispense correctly a prescription for an active ingredient and 37 believed that the pharmacist can swap any brand name drug with its generic counterpart. Most PICs showed an unsatisfactory level of conduct and knowledge of the professional and health legislation, which points to problems in the undergraduate and in-service training of pharmacists, that could jeopardize the national drug policy guidelines.

Effects of the acute exposition to glyphosate-based herbicide on oxidative stress parameters and antioxidant responses in a hybrid Amazon fish surubim (Pseudoplatystoma sp)

The aim of this study was to investigate the effects of acute glyphosate (active ingredient) exposure on the oxidative stress biomarkers and antioxidant defenses of a hybrid surubim (Pseudoplatystoma sp). The fish were exposed to different herbicide concentrations for 96 h. The thiobarbituric acid-reactive substances (TBARS), protein carbonyls and antioxidant responses were verified. The 15 mg a.p L-1 of herbicide resulted in the death of 50% of the fish after 96 h. An increase in liver and muscle TBARS levels was observed when fish were exposed to the herbicide. The protein carbonyl content was also increased in the liver (4.5 mg a.p L-1 concentration) and brain (2.25 mg a.p L-1 concentration). The antioxidant activities decreased in the liver and brain after exposure to herbicide. Levels of ascorbic acid in the liver (2.25 mg a.p L-1 and 4.5 mg a.p L-1 concentrations) and brain (2.25 mg a.p L-1 concentration) were increased post-treatment. Levels of total thiols were increased in the liver and brain (2.25 mg L-1 and 7.5 mg a.p L-1, respectively). Glyphosate exposure, at the tested concentrations affects surubim health by promoting changes that can affect their survival in natural environment. Some parameters as TBARS and protein carbonyl could be early biomarkers for Roundup exposure in this fish species. (C) 2014 Elsevier Inc. All rights reserved.

Assessing the effectiveness of 30% sodium chloride aqueous solution for the preservation of fixed anatomical specimens: a 5-year follow-up study

Anatomical specimens used in human or veterinary anatomy laboratories are usually prepared with formaldehyde (a cancerous and teratogenic substance), glycerin (an expensive and viscous fluid), or ethanol (which is flammable). This research aimed to verify the viability of an aqueous 30% sodium chloride solution for preservation of anatomical specimens previously fixed with formaldehyde. Anatomical specimens of ruminant, carnivorous, equine, swine and birds were used. All were previously fixed with an aqueous 20% formaldehyde solution and held for 7days in a 10% aqueous solution of the same active ingredient. During the first phase of the experiment, small specimens of animal tissue previously fixed in formaldehyde were distributed in vials with different concentrations of formaldehyde, with or without 30% sodium chloride solution, a group containing only 30% sodium chloride, and a control group containing only water. During this phase, no contamination was observed in any specimen containing 30% sodium chloride solution, whether alone or in combination with different concentrations of formaldehyde. In the second phase of the experiment, the 30% sodium chloride solution, found to be optimal in the first phase of the experiment, was tested for its long-term preservation properties. For a period of 5years, the preserved specimens were evaluated three times a week for visual contamination, odors, and changes in color and texture. There was no visual contamination or decay found in any specimen. Furthermore, no strange odors, or changes in color or softness were noted. The 30% sodium chloride solution was determined to be effective in the preservation of anatomic specimens previously fixed in formaldehyde.

Analysing the fate of nanopesticides in soil and the applicability of regulatory protocols using a polymer-based nanoformulation of atrazine

For the first time, regulatory protocols defined in the OECD guidelines were applied to determine the fate properties of a nanopesticide in two agricultural soils with contrasting characteristics. The nanoformulation studied had no effect on the degradation kinetics of atrazine indicating that (1) the release of atrazine from the polymer nanocarriers occurred rapidly relative to the degradation kinetics (half-lives 36-53 days) and/or that (2) atrazine associated with the nanocarriers was subject to biotic or abiotic degradation. Sorption coefficients, derived from a batch and a centrifugation technique at a realistic soil-to-solution ratio, were higher for the nanoformulated atrazine than for the pure active ingredient. Results indicate that the nanoformulation had an effect on the fate of atrazine. However, since the protocols applied were designed to assess solutes, conclusions about the transport of atrazine loaded onto the nanocarriers should be made extremely cautiously. The centrifugation method applied over time (here over 7 days) appears to be a useful tool to indirectly assess the durability of nanopesticides under realistic soil-to-solution ratios and estimate the period of time during which an influence on the fate of the active ingredient may be expected. More detailed investigations into the bioavailability and durability of nanopesticides are necessary and will require the development of novel methods suitable to address both the "nano" and "organic" characteristics of polymer-based nanopesticides.
