Efeitos do alcalóide indólico caulerpina, obtido de alga do gênero caulerpa, em modelo de colite experimental murina

As doenças inflamatórias intestinais são enfermidades onde a tolerância e homeostase da resposta inflamatória estão comprometidas, gerando lesões teciduais e favorecendo o surgimento de neoplasias. Há dois importantes exemplos de doenças inflamatórias intestinais, a colite ulcerativa, foco do modelo desse estudo, e a doença de Crohn. Os medicamentos utilizados no tratamento dessas doenças desencadeiam diversos efeitos adversos; além disso, em alguns pacientes, eles não são eficazes. Os extratos de algas têm demonstrado várias atividades biológicas, entre elas a atividade anti-inflamatória. Os extratos das algas do gênero Caulerpa foram utilizados em vários estudos, onde modelos inflamatórios foram analisados, entre eles o modelo de colite ulcerativa. A utilização do extrato metanólico da C. mexicana como terapêutica nesse modelo atenuou o quadro clinico desenvolvido pelos animais. Sendo assim, o presente estudo teve como objetivo analisar a ação terapêutica da Caulerpina (CLP), extraída da C. racemosa, no modelo murino de colite ulcerativa. Camundongos C57BL/6 machos foram expostos a uma solução de Dextrana Sulfato de Sódio (DSS) a 3% por sete dias. A partir do primeiro dia de exposição ao DSS os animais foram tratados em dias alternados com a CLP nas doses de 4 e 40 mg/kg e com a dexametasona (3 mg/kg) por via oral. O desenvolvimento da doença foi analisado através do índice de atividade da doença (IAD), que leva em consideração a perda de peso corporal, a consistência e a presença de sangue nas fezes. Após a eutanásia, o cólon foi removido e mensurado, e amostras do tecido colônico foram destinadas a análise histológica e à cultura para dosagem de citocinas. Os níveis de citocinas no sobrenadante da cultura do cólon foram mensurados por ELISA. O tratamento com a CLP (4 mg/kg) desencadeou significativa melhora quanto à perda de peso corporal e ao IAD, e atenuou o encurtamento do cólon em resposta ao DSS. Tal dose foi capaz de reduzir os níveis de citocinas pró-inflamatórias analisadas (TNF-, IFN-, IL-6, IL-17), mas não teve efeito significativo nas citocinas anti-inflamatórias IL-10 e TGF-. O tratamento com a CLP (40 mg/kg) não foi eficaz quanto a perda de peso e ao IAD, além de não ter atenuado a redução do cólon em resposta ao DSS. Essa dose conseguiu reduzir os níveis das citocinas pró-inflamatórias, porém não os níveis de IL-6. O tratamento com a dexametasona obteve melhora discreta quanto à perda de peso corporal e ao IAD, porém não atenuou a redução do cólon em resposta ao DSS. Esse tratamento também conseguiu reduzir todas as citocinas pró-inflamatórias testadas. Deste modo a CLP (4 mg/kg) demonstrou ser uma alternativa promissora no tratamento da colite ulcerativa, em razão dos seus efeitos benéficos sobre parâmetros clínicos, morfológicos e moleculares do modelo em estudo

Efeitos de um extrato aquoso de buzhong yi qi wan (fórmula magistral chinesa) na marcação de constituintes sanguíneos com tecnécio-99m, na morfologia e na fragilidade osmótica de hemácias de ratos Wistar

Technetium-99m (99mTc) has been used to obtain several radiobiocomplexes utilized to aid in the diagnosis of diseases. Blood constituents, as red blood cells (RBC) and plasma proteins, have been labeled with 99mTc. Natural and synthetic drugs can alter the labeling of these constituents. The aim of this work was to investigate the possibility of a Buzhong YiQi Wan extract to alter (i) the labeling of blood constituents with 99mTc, (ii) the RBC morphology, and (iii) osmotic fragility of RBC withdrawn from Wistar rats. The data showed that the BYQW extract (i) could affect labeling of blood constituintes with 99mTc, (ii) could affect the membrane integrity decreasing the osmotic resistance and (iii) could not alter the shape of RBC. Probably, these findings would be associated with properties of the substances present in the aqueous extract of BYQW. This study has multiple disciplinary aspects in knowledge areas: Radiobiology, Botanic, Phytotherapy and Haematology

Efeitos da temperatura do ar, linhagem e período do dia nas freqüências de ocorrências e tempos de expressão comportamental de matrizes pesadas

Ajustes de comportamento podem ocorrer rapidamente e a custo menor do que os ajustes fisiológicos. Considerando o comportamento social, é sugestivo que a freqüência e a intensidade de interações agressivas, o total de coesão social e a extensão de vícios sociais possam ser utilizados para avaliação de bem-estar. Esta pesquisa apresenta uma análise das interações entre os fatores experimentais, como temperatura, linhagem e período do dia, nos comportamentos de matrizes pesadas alojadas em câmara climática, buscando evidenciar as diferentes reações das aves submetidas a distintas condições ambientais. Os resultados encontrados mostraram diferenças significativas entre os comportamentos expressos pelas diferentes linhagens, reforçando a necessidade do monitoramento em tempo real do bem-estar de matrizes pesadas em alojamentos comerciais, dada a complexidade com que as variáveis ambientais interferem no bem-estar. A pesquisa permitiu concluir também que a avaliação do bem-estar de matrizes pesadas deve considerar o período do dia na observação dos comportamentos.

Centro de Informação sobre Medicamentos - CIM: avaliação da informação prestada

Providing information about medication, an essential function of pharmaceutical practice to ensure rational drug use, is an important activity of hospital pharmacy services. The Drug Information Center of Onofre Lopes University Hospital (DIC-HUOL) initiated its activities in 1979 with the first Clinical Pharmacy Service in Brazil. The aim of this study was to assess information provided by DIC-HUOL, describing the profile of passive information offered by the center. A retrospective cross-sectional study was conducted to identify the profile of information requests (IR). One hundred percent of the IR received by the DIC between January 2008 and December 2009 were used. The results were divided by year to determine the influence of the restructuring process that occurred in 2008 and 2009. The study at DIC-HUOL showed a mean of 5.5 IR/month in 2008 and 20.3 IR/month in 2009; the mean of the last year is comparable to that of other Brazilian DIC. Most of the IR were made by medical residents (22.7%) in 2008 and by pharmacists (32.5%) in 2009. The significant use of the DIC by medical residents may be due to its location in a university hospital. The most recurrent types of IR concerned issues related to pathway/mode of administration (16.8%) and drug stability (13.1%) in 2008 and 2009, respectively. Requests were made verbally in 100% of the cases in 2008 and 78.8% in 2009, owing to the fact that most of the DIC users were professionals from the hospital itself. Time elapsed between request and response was not reported in 83.3% and 21.3% of the cases in 2008 and 2009, respectively. The most widely used bibliographic source during the two years was MICROMEDEX®, with 41.9% and 39.2%, respectively. The restructuring process had a positive influence on the DIC-HUOL, exhibiting similar parameters to those of other Brazilian DIC, but some of these parameters must be improved to achieve international standards

Efeitos da simpaticotomia endoscópica sobre as artérias caróticas e vertebrais na terapêutica cirúrgica da hiperidrose primária

Analyze, in patients with primary hyperhidrosis (PH) who was undergone to videothoracoscopic sympathicotomy, the degree of vascular denervation after surgical transection of the thoracic sympathetic chain by measuring ultrasonografic parameters in carotid and vertebral arteries. Methods: Twenty-four patients with PH underwent forty-eight endoscopic thoracic sympathicotomy and were evaluated by duplex eco-doppler measuring systolic peak velocity (SPV), diastolic peak velocity (DPV), pulsatility index (PI) and resistivity index (RI) in bilateral common, internal and external carotids, besides bilateral vertebral arteries. The exams were performed before operations and a month later. Wilcoxon test was used to analyse the differences between the variables before and after the sympatholisis. Results: T3 sympathicotomy segment was the most frequent transection done (95,83%), as only ablation (25%) or in association with T4 (62,50%) or with T2 (8,33%). It was observed increase in RI and PI of the common carotid artery ( p<0,05). The DPV of internal carotid artery decreased in both sides (p<0,05). The SPV and the DPV of the right and left vertebral arteries also increased (p<0,05). Asymmetric findings were observed so that, arteries of the right side were the most frequently affected. Conclusions: Hemodynamic changes in vertebral and carotid arteries were observed after sympathicotomy for PH. SPV was the most often altered parameter, mostly in the right side arteries, meaning significant asymmetric changes in carotid and vertebral vessels. Therefore, the research findings deserve further investigations to observe if they have clinical inferences

Alcoolemia em vítimas fatais de acidentes de trânsito no Rio Grande do Norte empregando cromatografia em fase gasosa - head space

Alcohol is one of the few psychotropic drugs that their consumption has admitted legally and sometimes encouraged by the society. Studies show alcohol as the highest consumption of drugs among young people and society in general, probably because of its availability and easy access. The abuse causes public health problems, which was closely related to the violence, socioeconomic problems and the high number of automobile accidents. Transit is one of the main sectors affected by the effects of alcohol, observing a high incidence in the studies. About half of automobile accidents occurs after the consumption of alcoholic beverage, and the vast majority of cases related to high concentrations of alcohol in the bloodstream. The relationship of drunk with traffic accidents is in fact evident everywhere in the world, including Brazil, where studies have shown a high relationship between alcohol consumption and traffic accidents. This study determined the alcohol in fatal victims of traffic accidents in the state of Rio Grande do Norte and established the profile of this population compared with those found in Brazil and other countries. Samples of blood of ethanol added to fulfillment of the standardization of chromatographic conditions and procedures for the analysis, being employed in the determination of alcohol in blood samples of 277 victims of traffic accidents, collected at the Institute of Scientific Technical Police of Rio Grande do North (ITEP) in the year 2007. The blood alcohol level was determined in these samples correlated with the sex, age and marital status of the victim and the location, day of week and month when the accident occurred, is doing a statistical analysis and outlining a profile of the victims of an accident at transit in the state of Rio Grande do Norte. The parameters of standardization studied ensured the quality of the analytical method and, consequently, to obtain reliable laboratory results. Being given the best temperature for injector (150 ºC), detector (250 ºC) and column (50 ºC) with a flow of gas in the column of 2mL/minutos and analysis of time of 12 minutes. The method was linear in the range of 0.01 to 3.2 g / L (r2 = 0.9989) with average recovery of 100.2% and precision with coefficient of variation less than 15%. The analysis carried out on victims of fatal road traffic accidents, ethanol detected in the blood in 66.43% of the victims and these, 96% showed concentration ≥ 0.2 g / L, 87.73% of victims were male, while 12.27% female. The younger age group (1535 years) was the most involved (52,35%) and most single (55.60%). The accidents occurred with greater prevalence in the day on Monday (27%) followed by Sunday (24,19%) and Saturday (15,52%) and it was found that the prevalence of injuries varied between the different months of the year, and in February (14.4%) and April (10.47%) the months that had a higher number of accidents, however this oscillation showed no statistically significant difference. Also no significant difference was observed between the tracks of concentration found in men and women. The standardized method showed to be efficient, given satisfactorily to the goals of this work, and the high levels of alcohol found in victims of fatal road traffic accidents are consistent with several studies of literature, and the profile of the victim also supported by presenting in its most young adults, male and single

Avaliação in vitro e in vivo da Atividade Antioxidante do Extrato Hidroetanólico de Folhas de Turnera ulmifolia Linn. var. elegans (Turneraceae)

Recently, it has been a increasing interest in the antioxidative role of natural products to aid the endogenous protective biological systems against the deleterious effects of oxygen (ROS) and nitrogen (RNS) reactive species. Many antioxidant compounds, naturally occurring from plant sources. Natural antioxidants can protect and prevent the human body from oxidative stress and retard the progress of many diseases in which free radical are involved. Several plants used in the folk medicine to treat certain disorders that are accompanied by inflammation and other pharmacological properties have been proved their attributed properties, such antioxidant activity. Turnera ulmifolia Linn. var. elegans (Turneraceae), frequently employed by population as a medicinal plant, demonstrated antioxidant activity by in vitro and in vivo assays, using its leaf hydroethanolic extract (10%) he in vitro DPPH radical-scanvenging activity showed a strong antioxidant activity (86.57% ± 0.14), similar to Carduus marianus and catequine effects. For the in vivo assays, adult female Wistar rats (n=48) with carbon tetrachloride hepatic injury induced (2,5mL/kg i.p.) were used, Six groups or rats were uses (n=8) [G1 = control (1,25 mL/kg i.p. vehicle); G2 = CCl4 (2,5 mL/kg i.p.); G3 = CCl4 + extract 7 days (500 mg/kg p.o.); G4 = CCl4 + Legalon® 7 days (50 mg/kg p.o.), G5 = CCl4 + extract 21 days (500 mg/kg p.o.) e G6 = CCl4 + Legalon® 21 days (50 mg/kg p.o.)]. The hepatic oxidative injury was evaluated through biochemical parameters [alanine amino transferase (ALT), aspartate amino transferase (AST)] histopathological study, while thiobarbituric acid reactive products (TBAR), glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) levels were used to evaluate proantioxidant parameters. The plant extract tested was found effective as hepatoprotective as evidenced by a decreasing in the ALT and AST activities (p<0.001) and TBAR (plasma, p<0.001 and liver, p<0.001). Levels of GSH (blood, p<0.001 and liver, p<0.001) and antioxidant enzymes [CAT erythrocyte (p<0.05) and hepatic (p<0.01); SOD erythrocyte (p<0.001) and hepatic (p<0.001); GPx erythrocyte (p<0.001) and hepatic (p<0.001)] were also significantly increased. Histopathological changes induced by CCl4 were significantly reduced by the extract treatment. The data obtained were comparable to that of Legalon®, a reference hepatoprotective drug. The results showed that T. ulmifolia leaf extract protects against CCl4 induced oxidative damage. Therefore, this effect must be associated to its antioxidant activity, attributed to the phenolic compounds, present in these extract, which can act as free radical scavengers

Estudo de polimorfismos em genes relacionados ao metabolismo do ácido fólico e sua associação com o desenvolvimento de fendas orais não-sindrômicas

The congenital facial clefts are characterized by incomplete formation of the structures that separate the oral and nasal cavity. It is known that several environmental and genetic factors are involved in its development, among these, polymorphisms associated with folic acid metabolism have been investigated. In this sense, the objective was to observe the frequency of polymorphisms C677T and A1298C methylenetetrahydrofolate reductase gene (MTHFR), methionine synthase A2756G of (MTR), A66G of methionine synthase reductase (MTRR) A80G and the reduced folate carrier (RFC1) in patients with non-syndromic oral clefts, trying to match them with their development. Methods: We studied 140 patients with non-syndromic oral clefts and their mothers and 175 control subjects with their mothers, who underwent a questionnaire to obtain family information. Were collecting blood for DNA extraction from patients and their mothers to identify the genotypes of both by PCRRFLP, in addition to carrying out the determination of glucose, AST, ALT and serum creatinine, folic acid and vitamin B12 Serum and plasma homocysteine, and the hemogram. Results: Most patients have cleft lip and palate (55.8%), followed by isolated cleft palate (24.2%) and cleft lip (20%). Regarding gender, 62% of patients were male and 48% female and, after subdivision of the type of screwdriver according to sex was found a prevalence of males in the cracks of the type lip and palate (69 %) and lip (69.2%) and in the case of cleft palate was a female predominance (59%). The average concentration of serum folate in the group of mothers of cleft patients was significantly lower (13.8 ± 2.4 ng / mL) compared with the group of mothers of control subjects (18.8 ± 3.4 ng / mL) This was also observed for the group of cleft children as compared to controls, the dosage of folic acid had a significant difference with values of 15.6 ± 0.6 (ng / mL) and 17.9 ± 0.6 (ng / mL), respectively. For the biochemical measurements of glucose, AST, ALT and creatinine were not statistically different, nor was observed for haematological parameters performed. In assessing the frequency of polymorphisms C677T and A1298C MTHFR, A2756G MTR, MTRR A66G and A80G of the RFC1 there was no statistically significant difference in genotype distribution between cases and controls both for mothers and in the cleft. Conclusion: Although not observed association of polymorphisms with the development of cracks, the decrease in serum folate in the group of cleft patients and their mothers may reflect a disturbance in the metabolism of this metabolite, necessitating further studies such as studies methylation and expression to further elucidate the involvement of folate in the development of oral clefts

Avaliação dos efeitos de um extrato bruto de cianobactérias contendo microcistinas sobre o desempenho reprodutivo e a embriofetotoxicidade de ratos

The presence of cyanobacterial blooms in reservoirs intended for supply to the population can create public health problems for many species could produce potentially toxic compounds and these are not eliminated in the conventional procedures used in water treatment plants. So even in amounts less than the maximum allowable limit imposed by MS, cyanotoxins can be present in drinking water distributed to the population, creating a chronic exposure. There is little information about the long-term effects of oral exposure to cyanotoxins. This work aimed to show the exposure orally (v.o) of animals to a crude extract of cyanobacteria containing cyanotoxins to evaluate the reproductive performance of pregnant rats and their offspring and fertility of male rats. The presence of microcystins (MCs) in samples collected during the flowering processes in freshwater reservoirs in the Rio Grande do Norte, was analyzed by enzyme immunoassay and its variants have been identified and quantified by chromatographic methods. It was observed that by administration v.o. cyanobacterial extract containing MCs (40, 100 or 250 ng of MCs / kg / day) did not cause systemic toxicity in adult rats or effect on reproductive performance of male and female rats treated. It was also not observed any changes in skeletal study in the offspring of pregnant rats treated with the extract above. Because the solutions used contained MCs in a concentration equal to or greater than the tolerable daily intake for MCs, the results suggest, therefore, that the development of this work contributed to better assess public health risk as the oral exposure to cyanotoxins, increasing thus the credibility of the maximum allowable limit (LMP) of MCs in drinking water distributed to the population of several countries that use the LMP established by WHO in its legislation

Avaliação de efeitos toxicológicos e comportamentais de ginseng panax em ratos

Panax ginseng CA Meyer (Araliaceae) is a herbaceous plant widely used in China, South Korea, Japan and other Asian countries for the treatment of various diseases micro circulatory, cerebrovascular, among others, representing one of the drugs used by older man. It has over 30 biologically active ginsenosides with different pharmacological and behavioral effects and inhibitory effect on the NMDA receptor. The amino acid glycine is a co-agonist of the NMDA receptor, activating this receptor. At the cellular level, ketamine is widely known to be NMDA receptor antagonist. The aim of this study was to evaluate the general activity in the open field, and anxiety in elevated plus maze, mice treated with P. ginseng compared with the action of ketamine and glycine, to better understand the action of this herbal medicine at the NMDA receptor. We used 66 adult male rats were divided into six groups: a positive control, treated for 30 days with water by gavage, who received glycine (500mg/kg; po) on days 7, 14, 21 and 28 of treatment, one hour before of behavioral assessment, a negative control was treated for 30 days with water by gavage received ketamine (5mg/kg, ip) on days 7, 14, 21 and 28 of treatment, one hour prior to behavioral evaluation, three experimental groups, receiving 100, 200 or 300 mg / kg P. ginseng by gavage for 30 days and one group treated solely with white water, and is also administered 1 ml of water by gavage one hour prior to behavioral evaluation. Animal behavior in these three groups was also examined on days 7, 14, 21 and 28 of treatment. On day 30 of treatment, the animals were anesthetized with thiopental (70mg/kg) for blood collection and after euthanasia, withdrawal of various organs. There were no changes in weight and body weight gain and weight reasons in organ / body weight. However the consumption of water and food values showed a significant increase. Serum levels of AST was increased in a dose-dependently in the animals treated with doses of P. ginseng, glycine and ketamine as compared to the blank group. Unlike creatinine levels proved to be decreased in all treated groups when compared with white. However, the level of urea in these groups was reduced and no changes were observed in the ALT parameter. Histopathological examination revealed no changes in cell morphology in different tissues. There were no behavioral changes in the elevated plus maze and few changes were observed in the open field, animals treated with P. ginseng, glycine and ketamine when compared to white. These data suggest that the doses of P. ginseng employed were unable to induce general toxicity in rats treated for 30 days and also shows that the general behavior of mice treated with P. ginseng was slightly different from that observed in animals treated with ketamine and glycine. Finally, the study on the elevated plus maze showed that the extract of P. ginseng showed no anxiolytic or anxiogenic action

Períodos de matocompetição na cultura da soja (Glycine max (L.) Merril), cultivares Santa Rosa e IAC-2. I- efeitos sobre os parâmetros de produção

Visando estudar a influência do período de competição das plantas daninhas sobre alguns parâmetros de produção da cultura da soja, foram instalados experimentos de campo com os cultivares Santa Rosa e IAC-2 em dois tipos de solos, Latossol Roxo e Latossol Vermelho Escuro - fase arenosa, no município de Jaboticabal, Estado de São Paulo, Brasil. O delineamento experimental utilizado foi o de blocos ao acaso , sendo os cultivares mantidos sem e com competição das plantas daninhas por períodos cujas extensões foram 0, 10, 20, 30, 40, 50 e 60 dias após a emergência. Com base nos resultados obtidos, pode-se concluir que: o período mínimo do início do ciclo que deve ser mantido livre de competição é de 30 a 40 dias após a emergência para o cultivar Santa Rosa e de 50 dias para o 'IAC-2'; para os dois cultivares, a produção de grãos foi efetivamente aumentada após o 20.° dia sem competição no solo Latossol Roxo e 30.° dia no solo Latossol Vermelho Escuro - fase arenosa, atingindo um valor máximo no 50.° dia para o 'Santa Rosa' e ao redor do 60.° dia para o 'IAC-2'; no ano agrícola de 1977/78 (solo Latosso l Roxo), a competição durante os primeiros 20 dias após a emergência causou perdas de produção em ambos os cultivares, entretanto, no de 1978/79 (solo Latossol Vermelho Escuro - fase arenosa) este período foi de 40 dias, mostrando a importância das interferências e da foclimáticas e das diferentes espécies daninhas, no processo de competição; e, dentre todos os parâmetros relacionados à produção de grãos, o número de vagens por planta foi o mais afetado pela competição das plantas daninhas.

Reações do algodoeiro CNPA-ITA 90 ao cloreto de mepiquat

Com o objetivo de avaliar os efeitos de diferentes doses de cloreto de mepiquat aplicadas parceladamente no algodoeiro (Gossypium hirsutum L.) cv. CNPA-ITA 90, dois experimentos foram conduzidos durante os anos agrícolas de 1993/94 e 1994/95, na Fazenda Itamarati, Ponta Porã, MS. As doses estudadas foram: 1) 0,0; 2) 12,5+12,5+25,0 (50,0); 3) 25,0+25,0+25,0 (75,0); 4) 0,0+ 50,0+50,0 (100,0) e 5) 12,5+62,5+50,0 (125,0) g ha-1 de cloreto de mepiquat. O delineamento experimental utilizado foi o de blocos casualizados, com quatro repetições. As aplicações foram efetuadas aos 34, 47 e 62 dias após a emergência (DAE), em 1993/94, e aos 42, 60 e 73 DAE no ano de 1994/95, quando as plantas apresentavam altura média de 51, 84 e 93 cm e 61, 79 e 97 cm, respectivamente. Com o aumento da dose de cloreto de mepiquat, verificou-se redução da altura de plantas, da matéria seca foliar, do caule e do total da parte vegetativa, do número de nós, de ramos, do comprimento de ramos, do número de frutos danificados e do número de maçãs, e aumento do número de capulhos totalmente abertos.

Um sistema para gestão do conhecimento em ameaças, vulnerabilidades e seus efeitos

Attacks to devices connected to networks are one of the main problems related to the confidentiality of sensitive data and the correct functioning of computer systems. In spite of the availability of tools and procedures that harden or prevent the occurrence of security incidents, network devices are successfully attacked using strategies applied in previous events. The lack of knowledge about scenarios in which these attacks occurred effectively contributes to the success of new attacks. The development of a tool that makes this kind of information available is, therefore, of great relevance. This work presents a support system to the management of corporate security for the storage, retrieval and help in constructing attack scenarios and related information. If an incident occurs in a corporation, an expert must access the system to store the specific attack scenario. This scenario, made available through controlled access, must be analyzed so that effective decisions or actions can be taken for similar cases. Besides the strategy used by the attacker, attack scenarios also exacerbate vulnerabilities in devices. The access to this kind of information contributes to an increased security level of a corporation's network devices and a decreased response time to occurring incidents
