Item Histologia intestinal de tilápia do Nilo Oreochromis niloticus submetidas a diferentes níveis de suplementação do extrato hidroalcoólico de Anacaridium occidentale na dieta(2024-10-10) Silva, Klarissa Albuquerque Larocerie da; Silva, Suzianny Maria Bezerra Cabral da; http://lattes.cnpq.br/8569566022920336; http://lattes.cnpq.br/3138623022102113This study evaluated the effect of supplementation with the hydroalcoholic extract of Anacardium occidentale bark on the intestinal morphology of Nile tilapia (Oreochromis niloticus) fingerlings. After a 15-day acclimation period, during which the fish were maintained in 250-liter tanks, they were transferred to 40-liter experimental units at a density of 250 fish/m³ each. The hydroalcoholic extract of Anacardium occidentale bark was added to the diets administered to the animals at concentrations determined in the minimum inhibitory concentration (MIC) assays. Four treatments were evaluated: (i) commercial feed with 3% A. occidentale extract, (ii) commercial feed with 4% A. occidentale extract, (iii) commercial feed with 5% A. occidentale extract, and (iv) control group (commercial feed without extract addition), all with four replicates each. The experiment lasted 30 days, and the diets were offered three times a day (08:00, 12:00, and 16:00 hours) to apparent satiety. For histological analysis, five fish were collected at the beginning and one fish at the end of the experimental period (one per replicate for each treatment). The intestines were exposed in Petri dishes and divided into three segments: anterior, middle, and posterior. A 3 cm portion of the middle intestine was used, which was longitudinally cut to expose the villi. The total height, height, width, and thickness of the villi were measured. As a result, higher mean values for all intestinal morphology variables evaluated (height, total height, thickness, and width of the villi) were observed in the groups supplemented with 3%, 4%, and 5% of the hydroalcoholic extract of A. occidentale bark compared to the control group, with no differences among the treatments that received the extract. In conclusion, the supplemental use of the hydroalcoholic extract of Anacardium occidentale bark in the diet of Nile tilapia fingerlings resulted in a beneficial effect on the intestinal morphology of the supplemented animals, indicating improved development regarding intestinal health.Item Asteraceae medicinais ocorrentes no estado de Pernambuco(2021) Oliveira Neto, Edilton Vital de; Carvalho, Rejane Rodrigues da Costa e; http://lattes.cnpq.br/3307316028992311; http://lattes.cnpq.br/2968424927171398The use of medicinal plants and herbal medicines is considered an important practice to maintain the health of different social classes. In rural areas, residents often depend directly on available plant resources for their livelihoods. The Asteraceae family is considered the largest existing family of angiosperms, comprising about 25.000 species, many of them with medicinal potential. In this context, the present work had as objective the description of ten species of medicinal Asteraceae occurring in the Caatinga of the state of Pernambuco. The species studied were: Acanthospermum hispidum DC; Achyrocline satureioides (Lam.) DC; Acmella uliginosa (Sw.) Cass; Ageratum conyzoides L; Conyza sumatrensis (Retz.) E.H. Walker; Eclipta prostrata (L.) L; Egletes viscosa (L.) Less; Pluchea sagittalis (Lam.) Cabrera; Verbesina macrophylla (Cass.) S.F. Blake; and Vernonia polyanthes Less. The species were first described as to their morphology through the analysis of exsiccates and their different parts were illustrated. A literature review was also carried out to describe its main medicinal properties. In this way, we sought to contribute to the knowledge of medicinal species occurring in the Caatinga, especially those belonging to the Asteraceae family, thus facilitating their identification and use by the population.Item Plantas medicinais carrapaticidas utilizadas na práticae etoveterinária campeira(2022-05-24) Santana, Aline Soares de; Brasileiro, Hélida Maria de Lima Maranhão; http://lattes.cnpq.br/4735569144086617; http://lattes.cnpq.br/8889061104764965The use of plants for phytotherapic purposes is quite old and their knowledge is passed on through generations. Phytotherapy has been increasingly used in veterinary medicine for ectoparasites treatment. It is more economical and less harmful alternative to animals’ health and the environment. The excessive use of chemicals has increased ectoparasites resistance to treatment and their permanence time in the environment. The plants availability for the veterinary medicine is quite vast however it requires more studies. Based on the problem present, this review aimed to report the main species used to treat ticks in the rural ethnoveterinary practice.
