The birds were divided into five treatments with six repetitions each. Treatment (Ttm) 1 - group inoculated orally with 0.1 mL of sterile buffered saline 0.85% (placebo), Ttm 2 - phytogenic received additives in the feed at a dosage of 0.10 kg/ton feed of the initial age until 35 days (Contr. FA); Ttm 3 - group inoculated orally with 0.5 mL of buffered saline 0.85%, containing approximately 5.0X105 CFU/0.5mL Salmonella enterica serovars Enteritidis (Contr. positive SE); Ttm 4 - group inoculated orally with 0,5 mL of buffered saline 0.85%, containing approximately 5.0X105 CFU/0.5mL of SE and received as antimicrobial growth promoter (AGP) bacitracin methylene disalicylate at a dosage of 55 ppm in the feed until 35 days of age (SE + AGP); Ttm 5 - group inoculated orally with 0.5 mL of buffered saline 0.85%, containing approximately 5.0X105 CFU/0.5 mL SE received phytogenic additives in the feed at a dosage of 0.10 kg/ton of feed of 1 to 35 days old (SE + FA). Performance was evaluated and six birds for treatment were weighed, sacrificed and the pH of the gastrointestinal tract was measured. Fragments were collected duodenum and jejunum to histomorphometric analysis, morphometric lymphocyte count. There was significant difference in the period 1-35 of the experiment the average weight and weight gain of groups without microbial challenge, and feed conversion in the group feed with phytogenic. We observed greater higher villus height to 14 days in the duodenum and greater villus:crypt to the group that received phytogenic The pH was influenced by the AGP in the colon and caecum. There was no significant effect of treatment on biometry of organs and Salmonella groups. There was lymphoid depletion in spleen, bursa and caecal tonsils was variable, with a predominance of mild and moderate depletion. It is concluded that the additives phytogenic control the effects of SE in broilers as expressed in the performance, especially in the feed conversion, and histomorphometric of the intestine, although it has not prevented the migration of the SE for the lymphoid organs, as well as not stimulate the proliferation of lymphoid cells in broilers. / No presente estudo, foram utilizados 300 pintos com um dia de idade, machos, linhagem Cobb, com o objetivo de avaliar os efeitos dos aditivos fitogênicos sobre desempenho, a integridade intestinal e o sistema imunológico de frangos de corte inoculados experimentalmente com Salmonella enterica sorovar Enteritidis (SE). As aves foram divididas em cinco tratamentos com seis repetições cada. Tratamento (Ttm) 1 - grupo inoculado por via oral, com 0,1 mL de solução salina tamponada e esterilizada a 0,85% (Placebo); Ttm 2 - recebeu os aditivos fitogênicos na ração na dosagem de 0,10 kg/ tonelada de ração da fase inicial aos 35 dias de idade (Contr. AF); Ttm 3 - grupo inoculado via oral, com 0,5 mL de solução salina tamponada a 0,85%, contendo aproximadamente 5,0 X 105 UFC/0,5 mL de Salmonella enterica sorovar Enteritidis (Contr. positivo SE); Ttm - 4 - grupo inoculado por via oral, com 0,5 mL de solução salina tamponada a 0,85%, contendo aproximadamente 5,0 X 105 UFC/0,5 mL de SE e que recebeu como antimicrobiano promotor de crescimento (APC) a bacitracina metil dissilicato na dosagem de 55 ppm na ração até os 35 dias de idade (SE + APC); Ttm 5 - grupo inoculado por via oral, com 0,5 mL de solução salina tamponada a 0,85%, contendo aproximadamente 5,0 X 105 UFC/0,5 mL de SE que recebeu os aditivos fitogênicos na ração na dosagem de 0,10 kg/ tonelada de ração do 1º aos 35 dias de idade (SE + AF). Foram realizadas análises de desempenho e seis aves por tratamento foram pesadas, sacrificadas e o pH do trato gastrintestinal foi aferido . Coletou-se fragmentos de duodeno e jejuno para análises histomorfométricas, morfometrias e contagem de linfócitos. Observou-se diferença significativa, durante o período de 1-35 final do experimento no peso médio e no ganho de peso dos grupos sem desafio microbiano, além de melhor conversão alimentar no grupo alimentado com aditivos fitogênicos. Observou-se maior altura dos vilos aos 14 dias no duodeno e maior relação vilo:cripta para o grupo que recebeu fitogênicos O pH foi influenciado pelo APC no cólon e ceco. Não houve efeito significativo dos tratamentos sobre a biometria dos órgãos e Salmonella nos grupos. Observou-se a depleção linfóide nos baços, bursas e tonsilas cecais foi variável, com predominância de depleção discreta e moderada. Conclui-se que os aditivos fitogênicos controlam os efeitos da SE em frangos de corte como expresso nos dados de desempenho, especialmente na conversão alimentar, e dados histomorfométricos do intestino, embora não tenha impedido a migração da SE para os órgãos linfóides, bem como não estimulam a proliferação de células linfóide nos frangos de corte.

Estudo comparativo, randomizado para avaliar a eficÃcia terapÃutica da Mentha crispa e do secnidazol no tratamento da tricomonÃase / Trichomoniasis is a non-viral sexually transmitted disease most common in the world. The current treatment of this disease includes the use of several drugs, including herbal remedies formulated with Mentha crispa have also been used as protozoan The aim of this study was to evaluate the efficacy and safety of herbal medicine containing Mentha crispa in patients with vaginal trichomoniasis. The study was a randomized clinical trial, parallel and opened. It included 60 female volunteers, 35 from Fortaleza - Ceara and 25 from Sinop - Mato Grosso, who had stool examination of vaginal discharge positive for trichomoniasis. Patients were randomly distributed in two treatment groups, the Mentha crispa group and the Secnidazole group. Both groups were composed of 30 volunteers, in which, respectively, 2 tablets of 12 mg of herbal Giamebil and 2 tablets 1000mg Secnidal  were orally administered in single dose. The clinical trial consisted of three steps: pretreatment, treatment and post-treatment. To significance level of 5%, no difference was found between the groups (P = 0.6120), because the proportion of volunteers with no T.vaginalis in the Secnidazole group was 96.67% and the proportion found in the Mentha crispa group was 90.00%. Secondary endpoints for the evaluation of the effectiveness of Mentha crispa in the treatment of trichomoniasis were the improvement of clinical complaints: vaginal discharge, unpleasant odor, genital burning, dysuria, dyspareunia, pelvic pain and itching. It has not been demonstrated statistically significant difference (P = 0 , 4583) between the treatments in the proportion of patients who reported no such complaints. The drugs were considered well tolerated, as no voluntary needed additional pharmacological intervention in order to control or eradicate such discomfort. Therefore, adverse events were assessed as being mild, manifesting itself only once and having spontaneous remission. However, adverse effects were significantly higher (P = 0.0006) in the Secnidazole group (66.67%) than those found in the Mentha crispa group (20.00%). Adverse events reported by volunteers Secnidazole group were nausea (16.67%), the unpleasant odor in the urine (3.33%) and metallic taste, that was cited by 50% of patients and it showed a statistically significant difference between the treatment groups (P <0.001). The referred events by the volunteers of the Mentha crispa group were: epigastric pain, nausea, vomiting and headache reported by 3.33%, while unpleasant taste was mentioned by 6.67%. No signs of clinical toxicity was observed during treatment. This trial concluded that the herbal medicine containing Mentha crispa showed efficacy and safety when used orally at a dose of 24mg, presenting itself as an alternative therapy safe, effective, accessible and with quality for treatment in patients with trichomoniasis.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / TricomonÃase à a doenÃa sexualmente transmissÃvel nÃo-viral mais comum no mundo. O tratamento atual dessa patologia compreende o uso de vÃrios fÃrmacos, inclusive fitoterÃpicos formulados com Mentha crispa tambÃm tÃm sido empregados como antiprotozoÃrios. O objetivo desse estudo foi avaliar a eficÃcia terapÃutica e a seguranÃa do fitoterÃpico contendo Mentha crispa (GiamebilÂ) em pacientes com tricomonÃase vaginal. O estudo realizado foi um ensaio clÃnico do tipo randomizado, paralelo e aberto com 60 voluntÃrias do sexo feminino, sendo 35 procedentes de Fortaleza/Cearà e 25 da cidade de Sinop/Mato Grosso, que apresentaram exame parasitolÃgico positivo da secreÃÃo vaginal para tricomonÃase. As pacientes foram distribuÃdas aleatoriamente em dois grupos de tratamento, o grupo Mentha crispa e o grupo Secnidazol, ambos compostos de 30 voluntÃrias, os quais foram administrados por via oral, respectivamente, 2 comprimidos de 12 mg de Giamebil e 2 comprimidos de 1000 mg de SecnidalÂ, em dose Ãnica. O ensaio clÃnico foi constituÃdo de trÃs etapas: prÃ-tratamento, tratamento e pÃs-tratamento. Ao nÃvel de significÃncia de 5%, nÃo se constatou diferenÃa estatÃstica entre os grupos (P=0,6120), pois a proporÃÃo de voluntÃrias com ausÃncia de T.vaginalis no grupo Secnidazol foi de 96,67% e a verificada no grupo Mentha crispa foi de 90,00%. Os desfechos secundÃrios para a avaliaÃÃo da eficÃcia da Mentha crispa no tratamento da tricomonÃase foram a melhora das queixas clÃnicas: corrimento vaginal, odor desagradÃvel, ardor genital, disÃria, dispareunia, prurido e dor pÃlvica. NÃo foi demonstrada diferenÃa estatisticamente significante (P=0,4583) entre os tratamentos em relaÃÃo à proporÃÃo de pacientes que relataram ausÃncia dessas queixas. Os medicamentos foram considerados bem tolerados, pois nenhuma voluntÃria necessitou intervenÃÃo farmacolÃgica adicional no intuito de controlar ou debelar tal desconforto. Portanto, os eventos adversos foram avaliados como sendo de intensidade leve, manifestando-se uma Ãnica vez e com remissÃo espontÃnea. Entretanto, os efeitos adversos foram significativamente maiores (P = 0,0006) no grupo Secnidazol (66,67%) do que os verificados no grupo Mentha crispa (20,00%). Os eventos adversos relatados pelas voluntÃrias do grupo Secnidazol foram: nÃusea (16,67%), odor desagradÃvel na urina (3,33%) e gosto metÃlico, sendo que esse citado por 50% das pacientes evidenciou diferenÃa estatisticamente significante entre os grupos de tratamento (P <0,001). Os eventos referidos pelas voluntÃrias do grupo Mentha crispa foram: epigastralgia, nÃusea, vÃmito e cefalÃia referidos por 3,33%, enquanto gosto desagradÃvel foi mencionado por 6,67%. Nenhum sinal de toxicidade clÃnica foi observado no perÃodo de tratamento. O presente ensaio clÃnico concluiu que o fitoterÃpico contendo Mentha crispa apresentou eficÃcia terapÃutica e seguranÃa quando empregado por via oral na dose Ãnica de 24mg, apresentando-se como uma alternativa terapÃutica segura, eficaz, acessÃvel e de qualidade para o tratatamento de pacientes com tricomonÃase. / Trichomoniasis is a non-viral sexually transmitted disease most common in the world.

In this experiment we used 256 one-day-old male chicks, distributed in a completely randomized design with eight treatments, four replications with four replicates of eight birds each. The birds were orally inoculated at one-day-old with 0.5 ml of buffered saline, containing approximately 5.0 x 103 CFU / ml of Salmonella Infantis. Treatment 1 (T1) was the control group (Placebo); T2 - received garlic at a dose of 1.5%; T3 - received garlic at a dose of 3.0%; T4 - received garlic at a dose of 4.5%; T5 – was orally inoculated (Positive Control SI); T6 – was orally inoculated and treated with 1.5%; T7 – was orally inoculated and treated with 3.0%; T8 – was orally inoculated and treated with 4.5%. The performance was measured at seven, 21 and 35 days. At the days eight, 15 and 29 four birds for treatment were submitted to six hour fasting, and then they were weighed, euthanized, necropsied, and the organs were collected for weight determination and detection of Salmonella. Cloacal swabs were collected at three, 13, and 28 days and blood samples were collected at 14 and 36 days of age, after fasting for eight hours to evaluate blood parameters. At seven and 21 days, weight gain and final weight were lower in birds fed 4.5% of garlic, and there was no significant difference in the period of 1-35 days. The weight of the intestine and liver at 29 days was higher in birds inoculated and treated with 3.0% of garlic. Spleen weight was higher in birds inoculated at 29 days. Garlic did not inhibit Salmonella invasion in the spleen at the doses used. We found garlic did not reduce the intestinal E. coli population, but it reduced Salmonella. We observed garlic influenced cholesterol levels. In conclusion, fresh garlic in natura at the doses used does not alter the performance, as well as it does not inhibit the migration of Salmonella to the spleen; however, it influences serum cholesterol levels and reduces Salmonella fecal excretion of. / O presente estudo teve como objetivo avaliar os efeitos de diferentes doses do alho in natura no controle de Salmonella Infantis e suas consequências sobre o desempenho, excreção de Salmonella e parâmetros sanguíneos em frangos de corte experimentalmente inoculados. Foram utilizados 256 pintos machos de um dia de idade, distribuídos em delineamento inteiramente ao acaso com oito tratamentos, quatro repetições e oito aves por unidade experimental. As aves foram inoculadas via oral ao primeiro dia de idade com 0,5 mL de solução salina tamponada, contendo aproximadamente 5,0 x 103 UFC/mL de Salmonella Infantis. O tratamento 1 (T1) consistiu o grupo controle (Placebo); T2- recebeu o alho na dose de 1,5% na ração; T3- recebeu o alho na dose de 3,0% ; T4 – recebeu o alho na dose de 4,5%; T5- grupo inoculado via oral (Controle positivo Salmonella Infantis.); T6- inoculado via oral tratado com 1,5%; T7 – inoculado via oral tratado com 3,0%; T8 – inoculado via oral tratado com 4,5%. O desempenho foi avaliado aos sete, 21 e 35 dias. Aos oito, 15 e 29 dias quatro aves por tratamento foram submetidas a um jejum de seis horas, pesadas, eutanasiadas, necropsiadas e órgãos foram coletados para determinação do peso e para pesquisa de Salmonella. Foram coletados suabes de cloaca aos três, 13 e 28 dias de idade e amostras de sangue aos 14 e 36 dias de idade, após jejum de oito horas, para a avaliação dos parâmetros sanguíneos. Aos sete e 21 dias o ganho de peso e peso final foram menores nas aves que receberam 4,5% de alho, e não houve diferença significativa no período de 1-35 dias. O peso do intestino e do fígado aos 29 dias foi maior nas aves inoculadas e tratadas com 3,0% de alho. O peso do baço foi maior nas aves inoculadas aos 29 dias. Observou-se que o alho nas doses utilizadas não inibiu a invasão de Salmonella no baço e também não reduziu a população intestinal de E. coli, mas reduziu a de Salmonella. Observou-se que o alho influenciou os níveis de colesterol. Conclui-se que o alho in natura nas doses utilizadas não altera o desempenho, assim como não inibi a migração de Salmonella para o baço, mas influencia nos níveis séricos de colesterol e reduz a excreção fecal de Salmonella.
