Suicide rates have been rising all over the world. In Rio Grande do Norte state, a study carried out by Dutra (1999) investigated suicide rates among youngsters and found that in 1997 alone 244 cases of suicide attempt were registered. The author took an interest in studying this phenomenon among adolescents after reviewing Dutra s study and the technical literature on suicide. In addition to that, another topic caught her attention and raised new research questions: suicide attempts motivated by love, i.e., the end of a relationship, the fantasy of being abandoned by a partner. These have made the author to question how love manifested itself among adolescents and how it could become a reason for adolescents to give up their lives. Based on the data she analyzed and the research questions she developed, her research objective was to understand how adolescents who have attempted suicide because of love-related reasons have gone through this experience. The theoretical reference for the research was the Client-centered Therapy and more specifically, the construct self , according to Carl Rogers. The methodological strategy was inspired by the existential-phenomenological strategy. It used the narrative as a research instrument, inspired by the work of Walter Benjamim (1994) which was developed into a research strategy by Schmidt (1990). Four youngsters (three male and one female) have participated in this study. They have attempted suicide for love-related reasons during dolescence, when they were 12 to 18 years old. The interviews were recorded on cassette tapes, transcribed and literalized into narratives. The understanding of the narratives was based on the meanings that emerged from the youngsters speeches, as well as from the moments that touched the author. These moments highlighted the meaning of the experience of giving up life and the experience of love-based relationship as experienced by the youngsters. The study detected, among the adolescents who were interviewed, the existence of impulsiveness related to the suicide attempt. Also, the majority of the interviewees came from unstructured family backgrounds and had lost of one of their parents or had to face their parents divorce. The suicide was attempted by these youngsters through the ingestion of medicines. The research also revealed that the youngsters had regretted attempting suicide and felt guilty about it. With regards to their self-evaluation, the author observed that the youngsters had low self-esteem, negative perceptions about themselves and distorted views of themselves. These findings helped the author to reflect on the close relationship between the construct self and the suicide attempt. She also observed that a few factors, i.e., family context, education, social and cultural values, have influenced the way the youngsters perceived themselves . The results of this research confirm the idea that we have to understand the suicide attempt as a multi-determined phenomenon. This study contributed to the analysis and reflection on the factors that contribute to suicide attempts thus providing a foundation for the development of public health programs and policies to deal with this topic

This study used the Thermogravimetry (TG) and molecular absorption spectroscopy in UV-visible region to determine the iron content in herbal medicinal ferrous sulfate used in the treatment of iron deficiency anemia. The samples were characterized by IR, UV, TG / DTG, DTA, DSC and XRD. The thermoanalytical techniques evaluated the thermal stability and physicochemical events and showed that the excipients interfere in the decomposition of the active ingredients. The results of thermogravimetry showed that the decomposition temperature of the active principle Fe2(SO4)3 (T = 602 °C) is higher as compared to samples of tablets (566 586 °C). In the DTA and DSC curves were observed exothermic and endo events for samples of medicines and active analysis. The infrared spectra identified key functional groups exist in all samples of active ingredients, excipients and compressed studied, such as symmetric and asymmetric stretching of OH, CH, S=O. The analysis by X-ray diffraction showed that all samples had crystallinity and the final residue showed peaks indicating the presence of silicon dioxide, titanium dioxide and talc that are excipients contained in pharmaceutical formulations in addition to iron oxide. The results obtained by TG to determine the iron content of the studied drugs showed a variance when compared with those obtained by theoretical and UV-visible, probably due to formation of a mixture of Fe2O3 and Fe2(SO4)3. In one tablet was obtained FE content of 15.7 % and 20.6 % for TG by UV-visible, the sample EF 2 was obtained as a percentage of 15.4 % and 21.0 % for TG by UV-visible . In the third SF samples were obtained a content of 16.1 % and 25.5 % in TG by UV-visible, and SF 4 in the percentage of TG was 16.7 % and 14.3 % UV-visible

The concern with issues related to consumer protection has emerged in North America and then spread throughout the world. In Brazil, consumer‟s rights and interests only gained greater importance after their consolidation in the Constitution of 1988 and the enactment of the 8078/90 Law (Consumer‟s Protection and Defense Code), which established the consumerist microsystem. The understanding of the legal relationship of consumption concept is necessarily connected to knowledge of the elements that compose it. Among these, we can find the consumer and the provider (subjective elements), the product or service (objective elements), and the consumer‟s condition as final receiver of the consumption object (finalistic element). In order to elucidate the configuration of consumer protection before advertising communication, this work will analyze the advertising through the prism of consumerist laws, conceptualizing it and presenting a differentiation of it in relation to practices such as marketing, offer and commercial communication as well as examining its several kinds of manifestation, focusing mainly the ones categorized as misleading or unfair advertising. All kinds of advertising communication against the consumerist microsystem are subject to judicial control exercised by the State. Besides individual protection possibilities, this state-owned control can be collectively exercised as a result of the utilization of public civil action and popular action. Some specific categories of advertising (smoking products, alcoholic beverages, pesticides, medicines and therapies) are still subject to a set of particular restraints provided by the 9294/96 Law, which enables the performance of a special control in relation to them. In addition to state control, there is also a system of advertising communication self-regulation, which develops itself through the actions of the National Council of Advertising Self-Regulation that are based mainly on the laws established by the Brazilian Code of Advertising Self-Regulation and its annexes. However, this system of advertising self-regulation still has some deficiencies that hinder its effectiveness

Bisphosphonate-related osteonecrosis of the jaws is a relevant side-effect of these drugs that has been generating a great concern through increasing reports, worldwide, of this bone necrosis. Among several BRONJ hypothetical co-factors that could play a role in BRONJ pathogenesis, rheumatoid arthritis (RA) has been included as a relevant risk factor for BRONJ; however, until now the relationship between these diseases has not been fully explained. Thus, the purpose of this paper is to establish hypothetical factors that could link these two diseases, considering mainly inflammatory components and the organism effects of medicines used to treat RA, particularly steroids and methotrexate (MTX).

O interesse por medicamentos alternativos, principalmente daqueles provenientes de extratos naturais, tem aumentado nas últimas décadas. A Melaleuca alternifolia é um arbusto pertencente ao gênero Melaleuca, popularmente conhecida como árvore de chá, cujo principal produto é o óleo essencial (TTO - tea tree oil), de grande importância medicinal por possuir comprovada ação bactericida e antifúngica contra diversos patógenos humanos. em virtude da atividade terapêutica em diversas especialidades médicas, o TTO passou a ser empregado na área odontológica. Esta revisão de literatura foi realizada com o objetivo de discutir os ensaios já realizados com o TTO contra microrganismos relacionados à doença cárie, doença periodontal e problemas pulpares. O óleo de Melaleuca tem demonstrado boa ação antibacteriana in vitro contra microrganismos bucais, porém, pesquisas envolvendo o estudo do mecanismo de ação sobre as células microbianas ou estudos in vivo ainda são escassos e precisam ser realizados, já que esse produto pode ser útil na odontologia, seja na manutenção química da higiene ou prevenção de doenças bucais.

Medicamentos homeopáticos como o Symphytum officinalle e a Calendula officinallis são dotados de propriedades anti-sépticas, antiinflamatória, cicatrizantes e também agem como promotores da consolidação de fraturas ósseas. Neste trabalho, uniram-se esses dois medicamentos similares em um complexo para verificar o seu efeito no reparo em feridas de extração dentária em camundongos. O complexo Symphytum officinalle e Calendula officinallis nas potências de 6CH e 3CH, respectivamente, foi ministrado por via oral ao grupo tratado durante 5 dias antes e após a extração do incisivo superior direito. No grupo controle, administraram-se 5ml de álcool etílico a 70% diluídos em 30 ml de soro fisiológico. Após a proservação, os animais foram sacrificados, a maxila direita separada da esquerda, fixada e processada para inclusão em parafina. Após a microtomia, os cortes obtidos foram corados pela H/E. A análise histológica mostrou que, tanto no grupo controle como no tratado, o alvéolo dentário estava preenchido por tecido de granulação e tecido ósseo neoformado, com graus variáveis de maturação, rico em osteócitos. No entanto, nos animais tratados, o processo de reparo em feridas após extração dentária do incisivo superior direito mostrou um avanço progressivo de neoformação óssea mais acentuado quando comparado ao grupo controle, em tempos equivalentes. Estes resultados enfatizam as propriedades biológicas do complexo Symphytum officinalle e Calendula officinallis e sua possível utilização como recurso terapêutico na Odontologia.

OBJETIVO: O aumento do índice de massa corporal (IMC) tem sido associado a uma maior prevalência da asma em adultos. O presente estudo tem o objetivo de avaliar a associação entre a prevalência da obesidade e a gravidade da asma. MÉTODOS: Prontuários de duzentos asmáticos acima dos 20 anos de idade foram avaliados retrospectivamente. A asma foi classificada quanto à gravidade através da história clínica e do diagnóstico registrados, dos resultados da espirometria e da medicação prescrita. O IMC foi calculado e foram considerados obesos os pacientes com IMC > 30 kg/m². RESULTADOS: 23% dos pacientes apresentavam asma intermitente, 25,5%, asma persistente leve, 24%, asma persistente moderada e 27,5%, asma persistente grave. O IMC < 29,9 kg/m² foi observado em 68% dos pacientes e em 32% o IMC foi > 30 kg/m². O odds ratio da relação entre a obesidade e a gravidade da asma foi de 1,17 (CI95%: 0,90-1,53; p > 0,05). CONCLUSÕES: Na amostra estudada não foi encontrada correlação entre a obesidade e a gravidade da asma nem no sexo masculino, nem no feminino.

Ocimum gratissimum L. (Lamiaceae) and other species of the same genus are used as medicines to treat central nervous system (CNS) diseases, commonly encountered in warm regions of the world. The chemical composition of Ocimum gratissimum essential oil varies according to their chemotypes: timol, eugenol or geraniol. In this study, the essential oil type eugenol was extracted by hydrodistillation in each of the four seasons of the year. Activity upon CNS was evaluated in the open-field and rota-rod tests; sleeping time induced by sodium pentobarbital (PBS, 40 mg/kg, intraperitoneally, i.p.) and anticonvulsant activity against seizures induced by both pentylenetetrazole (PTZ; 85 mg/kg, s.c.) and maximal electroshock (MES, 50 mA, 0.11 s) were determined. Essential oils obtained in each season were effective in increasing the sleeping duration and a preparation obtained in Spring was able to protect animals against tonic seizures induced by electroshock. In each season, eugenol and 1,8-cineole were the most abundant compounds, and in Spring the essential oil presented the greatest relative percentage of sesquiterpenes, suggesting that these compounds could explain the differences observed in the biological activity in essential oils obtained in different seasons of the year.

Ailanthus excelsa (Roxb), an Egyptian medicinal species highly important for treating numerous diseases, was investigated against experimentally induced gastric ulcer in rodents. We evaluated the gastroprotective effect of four extracts (petroleum ether, diethyl ether, chloroform, and methanol) of A. excelsa bark by using the ethanol-induced gastric lesion model. The pretreatment of animals with methanolic, petroleum ether, and chloroformic extracts (100 mg/kg, oral (p.o.)) from A. excelsa significantly reduced gastric lesion induced by ulcerogenic agent (56, 47, and 70%, respectively) when compared with animals pretreated with vehicle. However, the diethyl ether pretreatment led to the least gastric lesion damage (83%), similar to the standard antiulcer drug, cimetidine, at the same dose (100 mg/kg, p.o.). The lower effective dose of diethyl ether extract, as well as cimetidine, given by intraduodenal route, significantly increased the pH values and reduced the acid output of gastric juice. Sterols, triterpenes, and quassinoids are present in the diethyl ether extract of A. excelsa stem bark, which presented the best gastroprotective action among the studied extracts. Our study confirmed the traditional indications of A. excelsa for the treatment of gastric ulcer.

Introduction: Propolis has plenty of biological and pharmacological properties and its mechanisms of action have been widely investigated in the last years, using different experimental models in vitro and in vivo. Researchers have been interested in the investigation of isolated compounds responsible for propolis action; however, there is lack of clinical research on the effects of propolis.Strategy and objectives: Since propolis-containing products have been marketed and humans have used propolis for different purposes, the goal of this review is to discuss the potential of propolis for the development of new drugs, by comparing data from the literature that suggest candidate areas for the establishment of drugs against tumors, infections, allergy, diabetes, ulcers and with immunomodulatory action.Conclusions: The efficacy of propolis in different protocols in vitro and in vivo suggests its therapeutic properties, but before establishing a strategy using this bee product, it is necessary to study: (a) the chemical nature of the propolis sample. (b) Propolis efficacy should be compared to well-established parameters, e.g. positive or negative controls in the experiments. Moreover, possible interactions between propolis and other medicines should be investigated in humans as well. (c) Clinical investigation is needed to evaluate propolis potential in patients or healthy individuals, to understand under which conditions propolis may promote health. Data point out the importance of this research field not only for the readers and researchers in the scientific community waiting for further clarification on the potential of propolis but also for the pharmaceutical industry that looks for new drugs.
