ABSTRACT Purpose: To evaluate the effects of the experimental subcutaneous Walker-256 tumor and L-glutamine supplementation, an antioxidant, on the glomerular morphology of rats. Methods: Twenty Wistar rats were distributed into four groups (n = 5): control (C); control treated with 2% L-glutamine (CG); rats with Walker-256 tumor (WT); and rats with Walker-256 tumor treated with 2% L-glutamine (WTG). Renal histological samples were submitted to periodic acid-Schiff and Masson’s Trichrome staining to analyze glomerular density, morphometry of glomerular components and glomerulosclerosis; and to immunohistochemistry for fibroblast growth factor-2 (FGF-2). Results: WT showed 50% reduction in body mass gain and cachexia index > 10%, while WTG demonstrated reduction in cachexia (p < 0.05). WT revealed reduction of glomerular density, increase in the glomerular tuft area, mesangial area, matrix in the glomerular tuft, decrease in the urinary space and synechia, and consequently higher glomerulosclerosis (p < 0.05). L-glutamine supplementation in the WTG improved glomerular density, and reduced glomerular tuft area, urinary space, mesangial area, and glomerulosclerosis compared to WT(p < 0.05). WT showed higher collagen area and FGF-2 expression compared to C (p < 0.05). WTG presented lower collagen fibers and FGF-2 expression compared to WT (p < 0.05). Conclusions: L-glutamine supplementation reduced cachexia and was beneficial for glomerular morphology of the rats, as well as it reduced kidney damage and improved the remaining glomeruli morphology.

ABSTRACT Purpose: To evaluate the long-chain fatty acid and major compounds levels in the feces after prophylactic oral use of Lacticaseibacillus casei in an experimental model of intestinal mucositis. Methods: Fifteen Swiss mice were randomly divided into three groups (n=5/group): The negative or positive control groups (n = 5) received saline orally for 18 days and an the intraperitoneal (i.p.) of saline or 5 Fluorouracil (450 mg/kg) in 15th day, respectability. L. casei group received oral concentration of L. casei (1x109 CFU/mL) for 18 days, the i.p. injection of 5-fluorouracil (450 mg/kg) in 15th days. Tissue samples from colon and each small intestine segment were collected for histopathological analysis. Stool samples were collected. Fecal composition of long-chain fatty acids and sterols were analysed by gas chromatography-mass spectrometry on the 15th and the 18th day. Results: The mucosa layer of all small intestine segments of animals from L. casei showed well preserved epithelium and glands, without necrosis signs, but Goblet cells number decreased. Several long-chain fatty acids and sterols have been identified before and after in the groups. L. casei administration after 5-FU treatment reduced concentrations of linoleic acid (18:2) (p < 0.001) and oleic acid (18:1) (p < 0.001) in feces. Conclusions: L. casei prevented the mucosal damage associated with 5-FU-induced intestinal mucositis reduced long-chain fatty acid levels in the feces.

Abstract Curcumin, contained at Turmeric (Curcumalonga), can exert many beneficial pleiotropic activities in the gastrointestinal tract. This study evaluated the antioxidant and anti-inflammatory activity of C. longa on 5-fluorouracil (5-FU)-induced oral mucositis (OM) in hamsters. Phytochemical analysis of crude C. longa extract (CLE) was performed to detect the presence of curcumin by TLC and HPLC. Golden Syrian hamsters were orally pre-treated with CLE (5, 50, or 100mg/kg). Cheek pouch samples were subjected to macroscopic and histopathological evaluation. ELISA was performed to quantify the inflammatory cytokines IL-1β and TNF-α. Superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA) levels were assessed by ultraviolet-visible spectroscopy analysis. Behavior analysis was conducted by the open field test. Curcumin content in the CLE was 0.55%m/m ± 0.0161 (2.84%). The group treated with 5mg/kg CLE showed healing evidence with macroscopic absence of ulceration (p<0.05) and microscopic aspect of re-epithelialization, discrete inflammatory infiltrate and absence of edema. Treatment with 5mg/kg CLE significantly increased GSH levels, and reduced MDA levels and SOD activity (p˂0.05), and decreased IL-1β (p˂0.05) and TNF-α (p˂0.01) levels. A significant reduction in walking distance, ambulation, speed, and rearing was observed for motor activity. Curcumin reduced oxidative stress, inflammation, and motor activity in hamsters with 5-FU-induced OM.

Abstract Objective The aim of this study was to evaluate the effects of gliclazide on oxidative stress, inflammation, and bone loss in an experimental periodontal disease model. Material and Methods Male albino Wistar rats were divided into no ligature, ligature, and ligature with 1, 5, and 10 mg/kg gliclazide groups. Maxillae were fixed and scanned using micro-computed tomography to quantify linear and bone volume/tissue volume (BV/TV) and volumetric bone loss. Histopathological, immunohistochemical and immunofluorescence analyses were conducted to examine matrix metalloproteinase-2 (MMP-2), cyclooxygenase 2 (COX-2), cathepsin K, members of the receptor activator of the nuclear factor kappa-Β ligand (RANKL), receptor activator of nuclear factor kappa-Β (RANK), osteoprotegerin (OPG) pathway, macrophage migration inhibitory factor (MIF), superoxide dismutase-1 (SOD-1), glutathione peroxidase-1 (GPx-1), NFKB p 50 (Cytoplasm), NFKB p50 NLS (nuclear localization signal), PI3 kinase and AKT staining. Myeloperoxidase activity, malondialdehyde and glutathione levels, while interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) levels were evaluated by spectroscopic ultraviolet-visible analysis. A quantitative reverse transcription polymerase chain reaction was used to quantify the gene expression of the nuclear factor kappa B p50 subunit (NF-κB p50), phosphoinositide 3-kinase (PI3k), protein kinase B (AKT), and F4/80. Results Micro-computed tomography showed that the 1 mg/kg gliclazide treatment reduced linear bone loss compared to the ligature, 5 mg/kg gliclazide, and 10 mg/kg gliclazide treatments. All concentrations of gliclazide increased bone volume/tissue volume (BV/TV) compared to the ligature group. Treatment with 1 mg/kg gliclazide reduced myeloperoxidase activity, malondialdehyde, IL-1β, and TNF-α levels (p≤0.05), and resulted in weak staining for COX-2, cathepsin k, MMP-2, RANK, RANKL, SOD-1, GPx-1,MIF and PI3k. In addition, down-regulation of NF-κB p50, PI3k, AKT, and F4/80 were observed, and OPG staining was strong after the 1 mg/kg gliclazide treatment. Conclusions This treatment decreased neutrophil and macrophage migration, decreased the inflammatory response, and decreased bone loss in rats with ligature-induced periodontitis.

Abstract Objectives: To study the intensity of inflammatory infiltrate and production of interleukin-1β (ll-1β), tumor necrosis factor-β (TNF-β), fibroblast growth factor-2 (FGF-2), glutathione peroxidase (GPX), and osteocalcin in response to in-office tooth bleaching in rats. Material and Methods: Twenty male Wistar rats were randomized into four groups (n=5) according to the received treatment (tooth bleaching or no treatment - control) and the period of euthanasia after treatment (24 h or 10 days). We performed tooth bleaching using a 38% hydrogen peroxide gel on maxillary and mandibular incisors. After euthanasia, incisors (20 per group) were processed for histological analysis, immunohistochemistry staining of ll-1β, TNF-β, FGF-2 and GPX and osteocalcin by immunofluorescence. We analyzed data using the Mann-Whitney and Kruskal-Wallis/Dunn tests (p<0.05). Results: The bleached groups presented statistically significant differences regarding the pulp inflammation stage compared with the control groups. Bleached teeth showed moderate/severe inflammatory infiltrate and control groups presented absent inflammatory cells or a negligible number of mononuclear cells (p<0.001) at two times (24 h and 10 days). There was strong staining for ll-1β, TNF-β, and GPX in bleached groups at 24 h and strong staining for ll-1β, TNF-β, GPX and FGF-2 at 10 days. After 10 days of tooth bleaching, the bleached group showed a statistically superior amount of osteocalcin than the other groups (p<0.01). Conclusions: Tooth bleaching with 38% hydrogen peroxide causes severe pulp inflammation, but characteristics of tissue repair after 10 days.

Resumo O objetivo do artigo é conhecer a distribuição e a frequência de consumo de ansiolíticos benzodiazepínicos, bem como avaliar a correlação entre consumo e características demográficas, epidemiológicas, econômicas e sociais. Estudo ecológico tendo como unidade amostral as 27 capitais brasileiras. A coleta de dados foi executada através do banco da Anvisa, para a dispensação do Alprazolam, Bromazepam, Clonazepam, Diazepam e Lorazepam, de 2010 a 2012, do Censo Demográfico 2010 (IBGE), Datasus e da pesquisa Demografia Médica. A análise estatística descritiva e a de regressão linear múltipla foram realizadas para análise dos dados. A região Norte possui as capitais com menores médias de consumo desses medicamentos e o Sudeste as mais elevadas. O consumo médio para a população de todas as capitais foi de 3,60 DHD. O Alprazolam é o mais dispensado pelas farmácias e drogarias particulares, com média de 2,00 DHD para as capitais. A análise de regressão linear múltipla demonstrou que 76% da variância do consumo foi explicada pela variação da densidade demográfica (β = 0,310 p = 0,045) e percentual de médicos (β = 0,507 p = 0,016). O consumo de ansiolíticos de meia vida curta vem crescendo ao longo dos anos, principalmente nas capitais de maior densidade demográfica e concentração de médicos.

Abstract The scope of this article is to determine the distribution and frequency of consumption of anxiolytic benzodiazepines and the correlation between consumption and demographic, epidemiological, economic and social characteristics. It is an ecological study with a sample of 27 state capitals. Data collection was performed through the ANVISA database for the dispensation of Alprazolam, Bromazepam, Clonazepam, Diazepam and Lorazepam in 2010-2012, the 2010 Demographic Census (IBGE), DATASUS and Medical Demographic Research. Descriptive statistical analysis and multiple linear regression analyses were performed for data analysis. The northern region has capitals with the lowest and the southeast has capitals with the highest average consumption of these products. The average consumption for the population of all capitals was 3.60 DHD. Alprazolam is the drug most dispensed by pharmacies and private drugstores with average 2.00 DHD for the capitals. Multiple linear regression analysis showed that 76% of the variation was explained by population density (β = 0.310 p = 0.045) and percentage of physicians (β = 0.507 p = 0.016). The consumption of short half-life anxiolytics has been on the increase, mainly in the cities of greater population density and concentration of physicians.

O objetivo desse trabalho foi avaliar a qualidade de cinco formulações de carbamazepina na dosagem de 200,00 mg: medicamento referência Tegretol® (Novartis), medicamento genérico (indústria nacional), medicamento similar (indústria nacional) e cápsulas do mesmo medicamento obtidas de duas farmácias de manipulação da cidade do Natal, RN. Os ensaios realizados foram: peso médio, diâmetro, espessura, teor, dissolução, desintegração, dureza, friabilidade e umidade. Foi observado que nenhuma das amostras analisadas apresentou friabilidade superior ao limite máximo determinado pela Farmacopéia Americana (1,5%). O medicamento genérico, apesar de apresentar dureza superior em relação ao medicamento de referência, desintegrou em menor tempo, o que pode estar relacionado à crospovidona presente na formulação. As amostras analisadas atenderam às especificações da Farmacopéia Brasileira no que diz respeito à dissolução. Em geral, os resultados das amostras A, B, C, D e E foram considerados satisfatórios uma vez que atenderam as especificações farmacopéicas. Embora a apresentação similar não tenha atendido ao padrão USP no que diz respeito à dureza, esse dado não se mostrou significativo, uma vez que o tempo de desintegração foi satisfatório.

The aim of this study was to evaluate the quality of five different solid formulations of carbamazepine. The reference formulation was Tegretol® 200.00 mg (Novartis) and the others were: generic formulation of carbamazepine 200.00 mg (National Industry), similar formulation of carbamazepine 200.00 mg (National Industry), and two formulations of carbamazepine 200.00 mg acquired from two different compounding pharmacies. The latter consisted of capsules obtained in Natal, the capital city of the Brazilian State of Rio Grande do Norte. The quality of samples was evaluated through physical and physical-chemical tests, including: weight, diameter, thickness, content, dissolution, disintegration, hardness, friability and moisture. The results of friability analysis showed that all formulations met Brazilian and United States Pharmacopeia (USP) specifications. In spite of having a higher hardness compared to the reference, the generic formulation had a lower disintegration time. This could be associated to the presence of crospovidone in its formulation. Results of this study showed that all formulations had dissolutions which were in accordance with Brazilian Pharmacopoeia specifications, and quality control tests. An exception was found for the similar formulation, which had a hardness parameter that exceeded the USP standard. However, this difference was not significant given the similar formulation's satisfactory disintegration time.

OBJETIVO: estudar o uso de medicamentos por gestantes atendidas durante o pré-natal em unidades básicas do Sistema Único de Saúde (SUS) na cidade de Natal, rio Grande do Norte, Brasil. MÉTODOS: foram entrevistadas 610 grávidas, entre o primeiro e o terceiro trimestre de gestação, que compareceram para consulta pré-natal em unidades de saúde localizadas nos quatro distritos sanitários de Natal, entre maio e julho de 2006. Os dados foram coletados com entrevistas estruturadas, baseando-se em perguntas uso-orientadas e medicamento-orientadas. Os fármacos foram classificados de acordo com o Anatomical Therapeutic Chemical Classification System (ATC) e segundo critérios de risco para a gestação da Food and Drug Administration (FDA). Utilizou-se teste do chi2 para análise dos dados. RESULTADOS: eram utilizados 1.505 medicamentos, obtendo-se uma média de 2,4 drogas por mulher. O uso de pelo menos um fármaco na gravidez foi relatado por 86,6% das gestantes. As classes mais utilizadas foram os antianêmicos (35,6% dos medicamentos), analgésicos (24,9%), drogas para distúrbios gastrintestinais (9,1%) e vitaminas (7%). De acordo com a classificação do FDA, dos medicamentos empregados 42,7% pertencem a categoria A de risco; 27,1% à categoria B, 29,3% à categoria C; 0,3 à categoria D e nenhum à categoria X. Foram usados, no primeiro trimestre da gestação, 43,6% dos fármacos. Observou-se maior uso de medicamentos quanto maior a escolaridade e a renda familiar da mulher. A automedicação ocorreu em 12,2% dos medicamentos; esse índice foi maior no primeiro trimestre de gravidez e em gestantes de baixa escolaridade e multigestas. CONCLUSÕES: as gestantes de Natal estão sendo expostas a uma variedade de medicamentos, cuja segurança na gravidez ainda é incerta, o que exige prescrição criteriosa para evitar possíveis danos ao feto.

PURPOSE: to study the use of medicines by pregnant women during prenatal care in clinics of the national public health system in the city of Natal, Brazil. METHODS: a total of 610 pregnant women between the first and the third trimesters of pregnancy were interviewed in the public clinics of the four sanitary districts of Natal, from May to July 2006. The data were collected by a structured questionnaire, based in use-oriented and medicine-oriented questions. The drugs were classified according to the Anatomical Therapeutic Chemical Classification System (ATC), in agreement with the gestation risk criteria from the Food and Drugs Administration (FDA). The statistical analysis was made by the chi2 test. RESULTS: a total of 1,505 drugs were used, with an average of 2.4 medications per woman. The use of at least one drug was found in 86.6% of the women. The most frequently used drugs were anti-anemics (35.6%), analgesics (24.9%), drugs for gastrointestinal disorders (9.1%) and vitamins (7%). According to the FDA classification, 42.7% belonged to category A risk, 27.1% to category B, 29.3% to category C, 0.3% to category D and none to category X. The use of medicines during the first trimester of pregnancy amounted to 43.6%. The rate of drug use increased with higher schooling level and family income. Self-medication was found in 12.2% of the drug intake and this rate was higher in the first trimester of gestation and with women with low education level and previous gestations. CONCLUSIONS: pregnant women from Natal are being exposed to a variety of medicines with uncertain safety in pregnancy. Therefore, more careful prescription is needed, to avoid possible fetal damage.

OBJETIVO: Verificar as variações quanto a sexo, idade, número e tempo de internação em pacientes com esquizofrenia. MÉTODOS: O estudo foi realizado no Hospital Doutor João Machado, referência estadual psiquiátrica, situado em Natal/RN - Brasil, no período de 1999 a 2005. O número de casos, o tempo de internação, a idade e o sexo foram coletados. Esses dados foram analisados pela estatística descritiva e Teste de Mann-Whitney com nível de significância de 5%. RESULTADOS: Durante esse tempo, 12.732 pessoas foram internadas. Os portadores de esquizofrenia corresponderam a 35,35% (4.501). A permanência no hospital foi de 44,33 ± 36,9 dias, diferente daquela observada nos não-portadores de esquizofrenia, 29,5 ± 61,6 dias (p < 0,0001). A idade média foi de 38,7 ± 13,5 anos, sendo a maioria dos pacientes do sexo masculino (65,78%). Em 1999, de cada 100 internados, 39,8 eram portadores de esquizofrênia; em 2005 essa proporção reduziu-se para 30,1. A esquizofrenia paranóide foi a mais freqüente, ocorrendo em 1.829 (40%) dos pacientes durante o período. CONCLUSÕES: O estudo aponta uma tendência à redução no número de doentes internados com esquizofrenia, bem como uma diminuição no tempo de internação.

OBJETIVE: To find out the variation range according to gender, age, number of admissions, and stay length in hospital for schizophrenic patients. METHODS: The study was performed in Doutor João Machado Hospital, Natal/RN - Brazil from 1999 through 2005. The number of cases, the stay length in hospital, the gender, and the age of the mentioned group were collected. This data was analyzed by descriptive statistics and Mann-Whitney Test with a 5% significance level. RESULTS: Over that time, 12,732 people were admitted. The schizophrenic patients corresponded to 35.35% (4,501). The stay length in the hospital was 44.33 ± 36,9 days, compared to 29.5 ± 61.6 days for non-schizophrenic patients (p < 0.0001). The average age was 38.7 ± 13.5 years and most patients (65.78%) were male. In 1999, 39.8 out of 100 admitted patients were schizophrenic; in 2005 this ratio was reduced to 30.1. Paranoid schizophrenia was the most prevalent type, reaching 1,829 (40%) patients during the study time. CONCLUSIONS: The study shows a trend to reduced number of patients admitted due to schizophrenia, as well as a reduced stay length in the hospital.

O objetivo do estudo foi apreender as representações sociais do cuidado à saúde bucal, buscando a compreensão desse saber construído na prática vivida por uma população de baixa renda do Nordeste brasileiro. Foram investigados 30 indivíduos moradores do bairro de Cidade da Esperança, Natal (RN) Brasil. A coleta de dados, realizada através de uma entrevista semi-estruturada, foi averiguada pela Análise de Conteúdo Temática (Bardin¹) e pelo software Alceste 4,5. A análise dos dados possibilitou a construção das categorias: Experiência de Dor e Perda Dentária. Se por um lado a Experiência de Dor indica o acesso restrito aos serviços odontológicos, por outro a Perda Dentária denuncia a existência de uma prática mutiladora imposta pelos serviços de saúde pública para solucionar a dor. Nesta categoria está presente ainda a prótese dentária, cujo desejo tem a sua possibilidade limitada pelas condições econômicas. As representações sociais do cuidado à saúde bucal salientam as conseqüências negativas da prática odontológica vigente e aponta para a necessidade de reestruturação dos serviços, levando em conta a percepção da população em relação ao cuidado à saúde bucal.

The objective of this study was identify the social representations of the oral care on daily activities to understand how the common sense works with the oral health, we realized the research with Brazilian northeast people. Thirty residents of Cidade da Esperança District, Natal, RN, Brazil were analyzed. The data was obtained from a semi-structured interview. The interviews were analyzed by Technique of Content Analysis (Bardin¹) as well as by Alceste 4.5 software. The categories were Toothache and Tooth Loss. The Toothache shows how the public health service is restrict. The Tooth Loss shows how the dentistry practice resolved the toothache, and how the prosthetics is limited by the social condition. The Social Representations of the oral care on daily activities show the negative consequences of the dentistry practice and the necessity of the new paradigm to the organization of the public health service taking into consideration the common sense about the oral care on daily activities.
