A infecção pelo Papilomavírus Humano (HPV) é o principal fator de risco para o desenvolvimento do referido câncer, estando presente em 90% dos casos de câncer de colo uterino na população mundial. Frente a busca por novos agentes quimioterapêuticos, os produtos naturais tem contríbuido intensamente para a identificação dessas substâncias e o desenvolvimento da terapêutica moderna. Maitenina, é um triterpeno quinonametídeo extraído das raízes da plana Maytenus ilicifolia, que possui algumas atividades biológicas já relatadas, como antifúngica, antiprotozoária e principalmente ação antitumoral. No momento não existem relatos na literatura relacionando a atividade da maitenina em células infectadas por HPV-16. O objetivo do presente estudo foi avaliar a citotoxicidade da maitenina em linhagem de carcinoma cervical infectada por HPV-16 (SiHa), não-infectada pelo vírus (C-33 A) e queratinócitos humanos imortalizados (HaCaT), bem como verificar a indução de apoptose e/ou necrose pelo ensaio de Hoechst e Iodeto de Propídeo e indução de apoptose pela atividade de caspase-3 nas três linhagens celulares, além de verificar alterações no ciclo celular das células tratadas com maitenina e o potencial de genotoxicidade e mutagenicidade, além de avaliar a proliferação das três linhagens. O ensaio de citotoxicidade foi realizado pelo método da sulforodamina B, e as três linhagens celulares foram tratadas durante 6, 12 ou 24 horas. Foi possível observar um efeito concentração e tempo resposta nas três linhagens analisadas. O CI50 foi de 3,26, 8,49 e 3,09 μM para as linhagens SiHa, C-33 A e HaCaT respectivamente, no tempo de tratamento de 24 horas. Com o intuito de avaliar o potencial efeito indutor de apoptose foi realizado o ensaio... / Cervical cancer is a worldwide public health problem, especially in developing countries, setting the fourth most common female cancer in the world. The infection by human papillomavirus (HPV) is the main risk factor for the development of this cancer, being present in 90% of cases of cervical cancer in the world population. Forward the search for new chemotherapeutic agents, natural products have strongly contributed to the identification of these substances and the development of modern therapeutics. Maytenin is a quinonemethide triterpene extracted from the roots of Maytenus ilicifolia plant, which has some biological activities previously reported as an antifungal, antiprotozoal and especially antitumor action. At the moment there are no reports in the literature relating the activity of maytenin in infected cells by HPV-16. The aim of this study was to evaluate the cytotoxicity of maytenin in cervical carcinoma line infected by HPV-16 (SiHa), non-infected by the virus (C-33 A) and by immortalized human keratinocytes (HaCaT), as well as verifying the induction of apoptosis and / or necrosis by Hoechst test and propidium iodide and the induction of apoptosis by caspase-3 activity in all three cell lines, in addition to check for changes in the cell cycle of treated cells with maytenin and the potential of genotoxicity and mutagenicity, and to evaluate the proliferation of the three cell lines. The cytotoxicity assay was performed by sulforhodamine B method and the three cell lines were treated during 6, 12 or 24 hours. It was possible to observe a concentration effect and response time in three lines analyzed. The IC50 was 3,26, 8,49 and 3,09 μM for SiHa, C-33 A and HaCaT lines respectively, in 24 hours treatment time. In order to evaluate the potential inductive effect of apoptosis it was performed a marking cytomorphological test with Hoechst and propidium iodide in 6 and 12 hours treatment times, and for the three cell lines it was ...

Ação de fármacos nas contrações da musculatura da cérvix de suínos

Padilha Nakaghi, Luciana Cristina [UNESP] 02 December 2015 (has links) (PDF)

Added 1 bitstream(s) on 2016-08-12T18:51:09Z : No. of bitstreams: 1 000864602.pdf: 1816573 bytes, checksum: 6157a42adc07f2a15ff7c8a76dcb8c16 (MD5) / A manipulação farmacológica da cérvix possui potencial importante na assistência à biotécnicas da reprodução, como inseminação artificial e transferência de embriões, em espécies que o acesso transcervical ao útero é muito difícil e, portanto, necessitam de procedimento cirúrgico para aumentar as taxas de concepção. Por meio de estudos básicos das propriedades mecânicas e farmacológicas da cérvix, objetivou-se com este estudo fornecer maior conhecimento da atividade da musculatura lisa da cérvix e então apresentar e discutir possibilidades de fármacos que possam relaxá-la e, portanto facilitar a passagem transcervical. Segmentos do músculo liso circular (MC) e longitudinal (ML) foram dissecados do útero (corno e corpo) e cérvix de suínos e preparados para tensão isométrica em banhos de órgão isolados de 20mL de solução modificada de Krebs-Henseleit (pH 7,4) gaseificada com 95% O2: 5% CO2 a 37°C. Os segmentos da cérvix apresentaram maiores respostas mecânicas do que os uterinos, mas exibiram menor atividade espontânea. Todas as preparações responderam de maneira dependente à frequência de estimulação de força elétrica (EFE, 2Hz - 32Hz, 300mA, por 30s). Especialmente na cérvix, após as respostas neurogênicas, houve um período de quiescência muscular importante até que as atividades espontâneas retornassem ao normal. Na maioria das preparações cervicais (MC e ML) a atropina aboliu as contrações neurogênicas, destacando um maior envolvimento para inervação colinérgica e receptores muscarínicos, mas uma pequena proporção das preparações se mostraram resistente à atropina. Estas respostas não foram afetadas pela fentolamina, e nem pela prazosina e fenilefrina, sugerindo a ausência de receptores alfa-adrenérgicos. L-NAME (N-nitro-L-arginina-metil-ester) não teve nenhum efeito sobre a atividade muscular cervical, excluindo o envolvimento de óxido nítrico. Diltiazem... / Pharmacological manipulation of cervix has a potentially important role for aiding either artificial insemination or embryo transfer in species requiring surgical procedures to aid conception. By studying basic pharmacological and mechanical properties of the cervix, we aimed with this study to provide a better knowledge about cervical smooth muscle activity and then present and discuss insights into possible drugs for the pig that could facilitate biotechnological procedures for reproduction. Circular (CM) and longitudinal (LM) smooth muscle strips were dissected from porcine uterus (cornu and corpus) and cervix and prepared for isometric tension recording in organ-bath of 20mL of modified Krebs Henseleit solution (pH 7.4) maintained at 37oC and gassed with 95% O2 and 5% CO2. Cervical strips produced larger mechanical responses than the uterine segments, but exhibited less spontaneous activity. All preparations responded in a frequency-dependent manner to electrical field stimulation (EFS, 2Hz-32Hz, 300mA for 30s) with a contraction. Especially in cervix, after neurogenic responses, there was a period of important muscular quiescence until the resume of normal spontaneous activity. In most cervical preparations (CM and LM) atropine abolished neurogenic contractions, highlighting a major role for cholinergic nerves and muscarinic receptors, but a small proportion of preparations exhibited atropine-resistant responses. These responses were not affected by phentolamine, and neither by prazosina and phenylephrine suggesting no role for alpha-adrenoceptors. L-NAME (N-nitro-L-arginina-metil-ester) did not affect the cervical smooth muscle activity, excluding the role of nitric oxide. Diltiazem, papaverine and isoprenaline inhibited neurogenic contractions in CM and LM strips of the cervix, consistent with important roles for voltage-sensitive calcium channels, phosphodiesterase and beta-adrenoceptors, respectively. However, RP73401 ...
