ABSTRACT Purpose: To evaluate the erectile function in patients who underwent partial penectomy and identify factors associated with penile functional status. Materials and Methods: We identified patients who underwent partial penectomy due to penile cancer between 2009 and 2014. Clinical and pathological characteristics included patient age at the time of diagnosis, obesity, hypertension, dyslipidemia, diabetes, smoking, metabolic syndrome, Eastern Cooperative Oncology Group (ECOG) status, penile shaft length, tumor size, primary tumor stage (pT), clinical nodal status, and local recurrence. Erectile function was assessed prospectively with the International Index of Erectile Function (IIEF-5) at least 3 months after partial penectomy. Results: A total of 81 patients met analysis criteria. At the diagnosis, the median age was 62 years (range from 30 to 88). Median follow-up was 17 months (IQR 7-36). Of total patients, 37 (45%) had T2 or higher disease. Clinically positive nodes were present in 16 (20%) patients and seven (8.6%) developed local recurrence. Fifty patients (62%) had erectile dysfunction (ED) after partial penectomy, 30% had moderate or severe erectile dysfunction scores. Patients with ED versus without ED were similar in baseline characteristics except for age, penile shaft length, and presence of inguinal adenopathy (p <0.05). Multivariate analysis using logistic regression confirmed that older patients, shorter penile shaft length, and clinically positive lymph node were significantly associated with ED. Conclusion: Partial penectomy due to penile cancer provides adequate local control of the disease, however, proper counselling is important especially in relation to ED consequences. Preservation of penile length yields to more optimal erectile recovery.

RESUMO Introdução: A trombose arterial é considerada uma doença multifatorial, resultante da interação de fatores de risco genéticos e adquiridos. Objetivos: O objetivo deste estudo foi investigar a presença dos polimorfismos nos genes do inibidor da ativação do plasminogênio tipo 1 (PAI-1) e da apolipoproteína E (ApoE), bem como suas interações com níveis de PAI-1 e lipídios e perfis de apolipoproteína, respectivamente, além das frequências desses polimorfismos e sua associação com trombose. Métodos: Noventa e sete pacientes [48 com acidente vascular cerebral isquêmico arterial (AVC) e 49 com doença arterial periférica (DAP)], tratados no serviço médico de hematologia, foram incluídos neste estudo. Os polimorfismos também foram investigados em 201 indivíduos-controle. Os polimorfismos foram investigados por reação em cadeia da polimerase-fragmento de restrição polimorfismo (PCR-RFLP). Resultados: Para o polimorfismo PAI-1, havia 54,2% genótipos heterozigotos (HT) e 12,5% genótipos de homozigoto (HM) no grupo dos pacientes, e 52,7% genótipos HT e 21,3% genótipos HM nos grupos-controle. Para o polimorfismo da ApoE, havia 56,3% (ε3ε3), 6,3% (ε4ε4), 8,3% (ε2ε3), 4,2% (ε2ε4) e 24,9% (ε3ε4) nos pacientes, e 61,2% (ε3ε3), 4,5% (ε4ε4), 8% (ε2ε3), 4,5% (ε2ε4) e 21,8% (ε3ε4) nos controles. Conclusão: Nenhuma diferença significativa foi observada comparando pacientes e controles. Neste estudo, não foi encontrada associação entre a presença dos polimorfismos avaliados e a ocorrência de eventos trombóticos.

ABSTRACT Introduction: Arterial thrombosis is considered a multifactorial disease, resulting from the interaction of genetic and acquired risk factors. Objectives: The aim of this study was to investigate the presence of the polymorphism in inhibitor of plasminogen activator type 1 (PAI-1) and apolipoprotein E (ApoE) genes and its interactions with PAI-1 levels and lipids and apolipoprotein profiles, respectively, as well as the frequencies of these polymorphisms and their association with thrombosis. Methods: Ninety-seven patients [48 with arterial ischemic stroke (IS) and 49 with peripheral arterial disease (PAD)], treated at the hematology medical service were included in this study. Polymorphisms were also investigated in 201 control subjects. Polymorphisms were investigated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: For the PAI-1 polymorphism, there were 54.2% heterozygous (HT) genotypes and 12.5% homozygous (HM) genotypes in the patients' group, and 52.7% HT genotypes and 21.3% HM genotypes in the controls. For the ApoE polymorphism, there were 56.3% (ε3ε3), 6.3% (ε4ε4), 8.3% (ε2ε3), 4.2% (ε2ε4) and 24.9% (ε3ε4) in the patients, and 61.2% (ε3ε3), 4.5% (ε4ε4), 8% (ε2ε3), 4.5% (ε2ε4) and 21.8% (ε3ε4) in the controls. Conclusion: No significant difference was observed by comparing patients and controls. In this study, no association was found between the presence of the evaluated polymorphisms and the occurrence of thrombotic events.

Abstract: En | Text: En | PDF: En

ABSTRACT Background. Hepatocellular carcinoma (HCC) is the most common malignancy that develops in cirrhotic livers. Its clinical and epidemiological characteristics and mortality rates vary according to geographical region. The objective of this study was to evaluate the clinical profile, epidemiological characteristics, laboratory parameters, treatment and survival of patients with HCC. Material and methods. Patients with HCC seen between 2000 and 2012 were studied. The Kaplan-Meier method was used for survival analysis according to variables in question. Results. The study included 247 patients with a mean age of 60 ± 10 years. There was a predominance of males (74%). The main etiologies of HCC were HCV infection (55%), excessive alcohol consumption (12%), and HBV infection (8%). Liver cirrhosis was present in 92% of cases. The mean tumor number and diameter were 2 and 5 cm, respectively. Patients meeting the Milan criteria corresponded to 43% of the sample. Liver transplantation was performed in 22.4% of patients of the Milan subset and in 10% of the whole sample. The overall mean survival was 60 months, with a 1-, 3- and 5-year survival probability of 74%, 40% and 29%, respectively. Lower survival was observed among patients with alcoholic etiology. Survival was higher among patients submitted to liver transplantation (P < 0.001), TACE (P < 0.001), or any kind of treatment (P < 0.001). However, no difference was found for surgical resection (P = 0.1) or sorafenib (P = 0.1). Conclusion. Patients with HCC were mainly older men diagnosed at an advanced stage. Treatment was associated with better overall survival, but few patients survived to be treated.

Plantas de cobertura podem proporcionar maior ciclagem de nutrientes. O trabalho objetivou determinar o efeito da aplicação anual de gesso e calcário à superfície do solo e de doses de fertilizantes à cultura anterior (soja), na produção de biomassa seca e no acúmulo de nutrientes por plantas de milheto cultivadas em sucessão, sob sistema plantio direto. O delineamento experimental foi em blocos casualizados, em esquema fatorial 4x4, com quatro repetições. Os tratamentos consistiram da combinação de quatro tipos de condicionadores de solo (calcário, calcário + gesso, gesso e controle), parcelados em três partes (2 t ha-1 de calcário e 1,0 t ha-1 de gesso; 2 t ha-1 de calcário e 1,0 t ha-1 de gesso; e 1 t ha-1 de calcário e 0,5 t ha-1 de gesso), com quatro níveis de adubação com P (superfosfato simples e triplo) e K (cloreto de potássio) (0%, 50%, 100% e 150% da adubação recomendada), aplicados na semeadura da cultura anterior (soja). O calcário proporcionou incrementos na produção de biomassa seca e no acúmulo de nutrientes (N, P, K Ca, Mg e S), pelas plantas de milheto. O gesso não proporcionou alterações na produção de biomassa seca do milheto. A utilização de doses crescentes de fertilizantes na cultura anterior (soja) aumentou a produção de biomassa seca, concentração e acúmulo de nutrientes nas plantas de milheto. O emprego do milheto como planta de cobertura, na entressafra, utilizando o efeito residual do fertilizante aplicado à cultura de verão, proporcionou ciclagem de nutrientes que pode ser utilizada pela cultura em sucessão.

Cover crops can provide a higher nutrient cycling. This study aimed to determine the effect of annual applications of gypsum and lime to the soil surface and of fertilizer doses to the previous crop (soybean) in the dry biomass production and nutrient accumulation by plants of pearl millet grown in succession, under no-tillage system. The experimental design was randomized blocks, in a 4x4 factorial scheme, with four replications. Treatments consisted of the combination of four types of soil conditioner (lime, lime + gypsum, gypsum and control), split in three parts (2 t ha-1 of lime and 1,0 t ha-1 of gypsum; 2 t ha-1 of lime and 1 t ha-1 of gypsum; and 1 t ha-1 of lime and 0.5 t ha-1 of gypsum), and four fertilizing rates with P (triple and simple superphosphate) and K (potassium chloride) (0%, 50%, 100% and 150% of the recommended fertilizing), applied at the sowing of the previous crop (soybean). Liming provided increments in the dry biomass production and in the accumulation of nutrients (N, P, K, Ca, Mg and S) by millet plants. The application of gypsum did not increase the millet dry biomass yield. The use of increasing rates of fertilizers in the previous crop (soybean) increased the biomass dry matter, density and accumulation of nutrients by millet plants. The intercropping of millet as a cover crop, with the residual effect of the fertilizer applied in the summer crop, provided a nutrient cycling that can be used by the following crops.

FUNDAMENTO: A principal causa de óbitos na cidade de São Paulo (SP) é por eventos cardíacos. Em hospitais periféricos de São Paulo estima-se a mortalidade hospitalar no infarto agudo entre 15% e 20%, pelas dificuldades existentes. OBJETIVO: Descrever a mortalidade intra-hospitalar do Infarto Agudo do Miocárdio com Supradesnivelamento de ST (IAMCSST) de pacientes admitidos via ambulância ou hospitais periféricos, como resultado da organização de uma estruturada rede de treinamento. MÉTODOS: Equipes de quatro prontos-socorros (Ermelino Matarazzo, Campo Limpo, Tatuapé e Saboya) e das ambulâncias avançadas do Serviço de Atendimento Móvel de Urgência (Samu) foram treinadas para uso de tenecteplase (TNK) ou para encaminhamento para angioplastia primária. Uma central de leitura de eletrocardiogramas foi usada quando necessário. Após uso de trombolítico, um hospital terciário recebia o paciente que era submetido a cinecoronariografia imediata (trombólise sem sucesso) ou entre 6 e 24 h, caso estável. Variáveis quantitativas, qualitativas foram avaliadas em análise uni e multivariável. RESULTADOS: De janeiro 2010 a junho 2011, 205 pacientes consecutivos utilizaram a rede de atendimento, ocorrendo 87 infartos de parede anterior, 11 bloqueios de ramo esquerdo, 14 bloqueios atrioventricular total, e em 14 houve reanimação pós-parada cardiorrespiratória inicial. A mortalidade intra-hospitalar foi de 6,8% (14 casos), a maioria por choque cardiogênico, um por acidente vascular encefálico hemorrágico e um por sangramento. CONCLUSÃO: A organização em instituições públicas de uma rede de tratamento, envolvendo diagnóstico, reperfusão, transporte imediato e hospital de retaguarda resultou em melhora imediata dos resultados de IAMCSST.

BACKGROUND: The major cause of death in the city of São Paulo (SP) is cardiac events. At its periphery, in-hospital mortality in acute myocardial infarction is estimated to range between 15% and 20% due to difficulties inherent in large metropoles. OBJECTIVE:To describe in-hospital mortality in ST-segment elevation acute myocardial infarction (STEMI) of patients admitted via ambulance or peripheral hospitals, which are part of a structured training network (STEMI Network). METHODS: Health care teams of four emergency services (Ermelino Matarazzo, Campo Limpo, Tatuapé and Saboya) of the periphery of the city of São Paulo and advanced ambulances of the Emergency Mobile Health Care Service (abbreviation in Portuguese, SAMU) were trained to use tenecteplase or to refer for primary angioplasty. A central office for electrocardiogram reading was used. After thrombolysis, the patient was sent to a tertiary reference hospital to undergo cardiac catheterization immediately (in case of failed thrombolysis) or in 6 to 24 hours, if the patient was stable. Quantitative and qualitative variables were assessed by use of uni- and multivariate analysis. RESULTS: From January 2010 to June 2011, 205 consecutive patients used the STEMI Network, and the findings were as follows: 87 anterior wall infarctions; 11 left bundle-branch blocks; 14 complete atrioventricular blocks; and 14 resuscitations after initial cardiorespiratory arrest. In-hospital mortality was 6.8% (14 patients), most of which due to cardiogenic shock, one hemorrhagic cerebrovascular accident, and one bleeding. CONCLUSION: The organization in the public health care system of a network for the treatment of STEMI, involving diagnosis, reperfusion, immediate transfer, and tertiary reference hospital, resulted in immediate improvement of STEMI outcomes.

OBJECTIVES: There is a direct relationship between the regression of left ventricular hypertrophy (LVH) and a decreased risk of mortality. This investigation aimed to describe the effects of anti-hypertensive drugs on cardiac hypertrophy through a meta-analysis of the literature. METHODS: The Medline (via PubMed), Lilacs and Scielo databases were searched using the subject keywords cardiac hypertrophy, antihypertensive and mortality. We aimed to analyze the effect of anti-hypertensive drugs on ventricle hypertrophy. RESULTS: The main drugs we described were enalapril, verapamil, nifedipine, indapamina, losartan, angiotensin-converting enzyme inhibitors and atenolol. These drugs are usually used in follow up programs, however, the studies we investigated used different protocols. Enalapril (angiotensin-converting enzyme inhibitor) and verapamil (Ca++ channel blocker) caused hypertrophy to regress in LVH rats. The effects of enalapril and nifedipine (Ca++ channel blocker) were similar. Indapamina (diuretic) had a stronger effect than enalapril, and losartan (angiotensin II receptor type 1 (AT1) receptor antagonist) produced better results than atenolol (selective β1 receptor antagonist) with respect to LVH regression. CONCLUSION: The anti-hypertensive drugs induced various degrees of hypertrophic regression.

OBJETIVO: Verificar a eficácia da mobilização neural e do alongamento estático na redução da dor em ratos submetidos à ciática experimental. MÉTODOS: Os ratos (n=23) foram divididos em três grupos: simulacro (GS/n=8), sem intervenção; alongamento (GAL/n=8), tratados com alongamento estático; e mobilização neural (GMN/n=7), tratados com mobilização neural. Submeteram-se os animais a um modelo experimental de ciática, comprimindo o nervo isquiático direito com fio de catgut. Realizaram-se cinco sessões consecutivas de tratamento que se iniciaram no terceiro dia pós-lesão. Avaliou-se a dor, provocada pela ciática, pelo teste de incapacidade funcional que mensurava o tempo de elevação da pata (TEP) do animal, e valores maiores que 10 segundos eram indicativos de dor. O TEP foi mensurado nos momentos: antes da lesão (M1), imediatamente antes (M2), após a 1ª sessão (M3), imediatamente após a última sessão (M4) e 24 horas após a última sessão (M5). Aplicou-se ANOVA com medidas repetidas e não repetidas para análise intra e intergrupos, respectivamente. RESULTADOS: No GS, os TEPs no pós-lesão foram maiores que M1(p<0,001), sugerindo persistência da dor. No GAL, os TEPs foram maiores no pós-lesão em relação a M1 (p<0,001), mas diminuiu nas comparações M3xM4 (p<0,05) e M3xM5 (p<0,01) sugerindo a eficácia do tratamento. No GMN, M2, M3 (p<0,001) e M4 (p<0,05) foram maiores em relação a M1, mas M5 não, mostrando que este tratamento restabeleceu os valores normais de TEP. CONCLUSÃO: As duas formas de terapia foram eficazes na redução da dor, sendo a mobilização neural mais efetiva.

OBJECTIVE: To verify the effectiveness of neural mobilization and static stretching in reducing pain in rats submitted to experimental sciatica. METHODS: The rats (n=23) were divided into three groups: sham (SG/n=8), without intervention; stretching (STCG/n=8), treated with static stretching; and neural mobilization (NMG/n=7), treated with neural mobilization. The animals underwent an experimental model of sciatica by compression of the right ischiatic nerve with catgut suture thread. There were five consecutive sessions of treatment that began on the third day after lesion. The pain caused by the sciatica was evaluated by a functional incapacitation test that measured paw elevation time (PET), and values over 10s were indicative of pain. PET was measured at the following moments: before the lesion (M1), immediately before (M2) and after the first session (M3), immediately after the last session (M4) and 24h after the last session (M5). ANOVA was applied with repeated measures and unrepeated measures for intra- and inter-group comparison, respectively. RESULTS: In the SG, post-lesion PETs were greater than M1 (p<0.001), suggesting persistence of pain. In the STCG, post-lesion PETs were greater than M1 (p<0.001), but lower when comparing M3 vs. M4 (p<0.05) and M3 vs. M5 (p<0.01) suggesting the effectiveness of the treatment. In NMG, M2, M3 (p<0.001) and M4 (p<0.05) were greater in relation to M1, but not M5, showing that this treatment reestablished the normal PET values. CONCLUSION: Both forms of therapy were effective in reducing pain, with neural mobilization being the more effective of the two.

Neobenedenia melleni (MacCallum, 1927) é um conhecido patógeno de teleósteos confinados que exibe baixo grau de especificidade ao hospedeiro. Entre julho de 2006 a junho de 2007, 120 espécimes de Trichiurus lepturus Linnaeus, 1.758 foram adquiridos de pescadores locais na Baia de Guanabara (22º 57' S e 42º 41' O), Estado do Rio de Janeiro, Brasil, para o estudo da sua parasitofauna. A superfície do corpo foi raspada e os monogenéticos obtidos foram identificados como N. melleni, que apresentaram prevalência de 8,3% e intensidade média de infecção 1,2 ± 0,42. O presente trabalho teve como objetivo fazer o primeiro registro de N. melleni parasitando hospedeiro silvestre na costa brasileira, aumentando, dessa forma, a distribuição geográfica conhecida dessa espécie de parasito.

Neobenedenia melleni (MacCallum, 1927) is a widely spread pathogen in teleost maricultures with a very low host specificity. Between July of 2006 to June of 2007, 120 specimens of Trichiurus lepturus Linnaeus, 1758 were acquired of local fishermen in the Guanabara Bay (22º 57' S and 42º 41' W), State of Rio de Janeiro, Brazil, to the study of the parasite fauna. The surface of the host body was scraped and the monogeneans obtained were identified as N. melleni, which showed prevalence of 8.3% and mean intensity of infection 1.2 ± 0.42. Data about morphology of the specimens collected were included herein. Neobenedenia melleni is recorded by the first time parasitizing on a wild host from the Brazilian coastal zone.

Foram avaliadas 7 espécies da mastofauna e 36 da avifauna quanto à prevalência e intensidade de infestação por carrapatos na ESALQ/USP, no Município de Piracicaba, SP. Analisaram-se 52 indivíduos da mastofauna e 158 da avifauna, parasitados por 12418 carrapatos. Os exemplares adultos (N= 7343) foram encontrados em parasitismo nas capivaras enquanto que os imaturos foram, na maioria, coletados de pequenos mamíferos e aves. Os principais hospedeiros para as formas imaturas, em ordem decrescente, foram gambás (69,1%), capivaras (24,4%) e urubus (3,7%). Entre a avifauna, o urubu apresentou o maior número de carrapatos com 69,9%, seguido por indivíduos das famílias Thamnophilidae e Turdidae. Os carrapatos adultos encontrados em capivaras foram A. cajennense (80,8%) e A. dubitatum (19,2%). Ambas as espécies foram também coletadas em gambás, correspondendo a 72,4% e 27,6%, respectivamente. Pela facilidade de captura e atratividade de Amblyomma spp. o gambá pode ser usado como bioindicador de infestação em locais endêmicos para febre maculosa. Considerando os índices de parasitismo e prevalência bem como de abundância de carrapatos, susceptibilidade dos hospedeiros, proliferação e susceptibilidade para infecção por R. rickettsi, capivaras e gambás são potenciais hospedeiros amplificadores desse microrganismo no Campus da ESALQ, enquanto eqüídeos, urubus e gatos atuam como hospedeiros secundários.

Seven species of mammals and 36 of birds were investigated to determine the tick prevalence and intensity of infestation. The study was conducted at the Esalq/USP in Piracicaba municipality, State of São Paulo. It was collected 52 mammals and 158 birds parasitized by 12,418 ticks. Adult ticks (N= 7,343) were found on capybaras, while the immature were mainly collected on small mammals and birds. The main hosts for immatures in descending order were opossums (69.1%), capybara (24.4%) and black vultures (3.7%). Among the avifauna, the black vulture (Cathartidae) had the heaviest infestation (69.9%) followed by species of the Thamnophilidae and Turdidae families. Adult ticks collected on capybaras were A. cajennense (80.8%) and A. dubitatum (19.2%). Both tick species were also found on opossums corresponding to 72.4% and 27.6%, respectively. Due to easy capture and attractiveness for ticks, opossums could be used as bioindicators in Brazilian zoonotic areas with spotted fever. Considering the prevalence and also abundance of ticks, host attractiveness, proliferation and susceptibly for R. rickettsi infection, capybaras and opossums are the main amplifying hosts for this microorganism at the ESALQ/Campus, while horses, black vultures and stray cats act as secondary hosts.

Durante o estudo dos metazoários parasitos de Paroaria dominicana (Linnaeus, 1758), oito infrapopulações de Mediorhynchus emberizae (Rudolphi, 1819), foram coletadas no terço médio do intestino delgado, com intensidades parasitárias variando de um a dez espécimes. Diferenças entre os valores médios da biomassa, volume dos ovos, volume dos testículos e da densidade parasitária das diferentes infrapopulações foram estatisticamente testadas com o objetivo de detectar variações desses parâmetros em função da densidade parasitária. Foi observado que a biomassa de acantocéfalos aumentou com o volume do intestino e também que a densidade dos parasitos aumentou com a intensidade parasitária nas infrapopulações. Verificou-se que o aumento da intensidade parasitária foi acompanhada pela diminuição da biomassa média dos parasitos. Constatou-se diminuição do volume dos ovos com o aumento da densidade e da intensidade parasitária. Os resultados do presente trabalho parecem dar indícios da ocorrência de fatores dependentes da densidade e da diminuição do volume testicular e a biomassa dos machos com o aumento da densidade parasitária nas infrapopulações de M. emberizae no intestino de P. dominicana.

During the study of the metazoan parasites of Paroaria dominicana (Linnaeus, 1758), eight infrapopulations of Mediorhynchus emberizae (Rudolphi, 1819), were collected in the medium third of the small intestine, with parasite intensities ranging from one to ten specimens. Differences among the average values of the biomass, volume of the eggs, volume of the testicles and the parasite density of the infrapopulations were statistically tested in order to detect variations of these parameters in function of parasite density. Was observed that the acanthocephalans biomass increased with the volume of the intestine and also that the parasite density increased with the parasite intensity in the infrapopulations. It was verified that the increase of the parasite intensity was accompanied by the decrease of the mean biomass of the parasites. Decrease of the volume of the eggs was verified with the increase of the density and of the parasite intensity. The results of the present work could suggested the occurrence of density-dependent factors and the decrease of testicles volume and the biomass of the males with the increase of the parasite density in the infrapopulations of M. emberizae in the intestine of P dominicana.

O objetivo deste trabalho foi selecionar plantas com atividade inseticida, para isolar, identificar e avaliar a bioatividade de compostos inseticidas presentes nessas plantas, contra as seguintes pragas de produtos armazenados da ordem Coleoptera: Sitophilus zeamais Mots. (Curculionidae), Rhyzopertha dominica F. (Bostrichidae) e Oryzaephilus surinamensis L. (Silvanidae). As espécies de plantas usadas foram: anis (Ocimum selloi Benth), arruda (Ruta graveolens L.), cordão-de-frade (Leonotis nepetifolia L.), datura (Datura stramonium L.), erva baleeira (Cordia verbenacea L.), hortelã (Mentha piperita L.), melão-de-são-caetano (Mormodica charantia L.) e mentrasto (Ageratum conyzoides L.). Avaliou-se a toxicidade dos extratos hexânico e etanólico dessas plantas sobre R. dominica. Somente o extrato hexânico de A. conyzoides apresentou atividade inseticida. O extrato hexânico desta planta foi fracionado, sucessivamente, por cromatografia de coluna de sílica gel, para isolamento e purificação dos compostos ativos. Os compostos 5,6,7,8,3',4',5'-heptametoxiflavona; 5,6,7,8,3'-pentametoxi-4',5'-metilenodioxiflavona e cumarina foram identificados. Entretanto, somente a cumarina apresentou atividade inseticida às três espécies de insetos (DL50 de 2,72 a 39,71 mg g-1 de i.a.). A ordem crescente de suscetibilidade à cumarina foi R. dominica, S. zeamais e O. surinamensis.

The objective of this work was to screen plants with insecticide activity, in order to isolate, identify and assess the bioactivity of insecticide compounds present in these plants, against Coleoptera pests of stored products: Oryzaephilus surinamensis L. (Silvanidae), Rhyzopertha dominica F. (Bostrichidae) and Sitophilus zeamais Mots. (Curculionidae). The plant species used were: basil (Ocimum selloi Benth.), rue (Ruta graveolens L.), lion's ear (Leonotis nepetifolia (L.) R.Br.), jimson weed (Datura stramonium L.), baleeira herb (Cordia verbenacea L.), mint (Mentha piperita L.), wild balsam apple (Mormodica charantia L.), and billy goat weed or mentrasto (Ageratum conyzoides L.). The insecticide activity of hexane and ethanol extracts from those plants on R. dominica was evaluated. Among them, only hexane extract of A. conyzoides showed insecticide activity; the hexane extract of this species was successively fractionated by silica gel column chromatography, for isolation and purification of the active compounds. Compounds 5,6,7,8,3',4',5'-heptamethoxyflavone; 5,6,7,8,3'-pentamethoxy-4',5'-methilenedioxyflavone and coumarin were identified. However, only coumarin showed insecticide activity against three insect pests (LD50 from 2.72 to 39.71 mg g-1 a.i.). The increasing order of insects susceptibility to coumarin was R. dominica, S. zeamais and O. surinamensis.
