Ação dos ésteres do ácido ricinoléico do óleo de mamona nas glândulas salivares e nos ovários de carrapatos Rhipicephalus sanguineus (Latreille, 1806) (Acari : Ixodidae). Análise histológica /Arnosti, André. January 2011 (has links)
Orientador: Maria Izabel Camargo Mathias / Banca: Gislaine Cristina Roma / Banca: Gilberto Orivaldo Chierice / Banca: Roberta Cornelio Ferreira Nocelli / Banca: Gervasio Henrique Bechara / Resumo: O presente trabalho traz informações que mostram a interferência dos ésteres do ácido ricinoléico extraídos do óleo de mamona (Ricinus communis), no ciclo secretor das glândulas salivares e na vitelogênese de fêmeas do carrapato Rhipicephalus sanguineus, agindo diretamente nos processos de alimentação e de reprodução, respectivamente. Para a realização deste estudo, coelhos hospedeiros infestados com carrapatos, foram alimentados com ração comercial comum (controle-GC) e com ração enriquecida com os ésteres em diferentes concentrações (tratamento- GT). As glândulas salivares sofreram danos, e tiveram o citoplasma das células acinares alterado, trazendo prejuízos ao seu funcionamento, além desta substância ter acelerado a degeneração do órgão como um todo. Os ésteres interferiram na atividade de secreção celular alterando a composição da glicoproteína salivar, especialmente nas células glandulares dos ácinos II. O efeito dos ésteres na vitelogênese foi observado nos ovócitos dos carrapatos do grupo tratamento (GT), os quais apresentaram células germinativas com alterações citoplasmáticas, inibição do desenvolvimento dos ovócitos I e II para os estágios avançados (IV e V), além da interferência na maturação dos ovócitos V. Além disso, nas ampolas dos ovários dos indivíduos tratados, espermatozóides não foram observados no seu interior confirmando a ação dos ésteres no processo de reprodução. Ficou demonstrado também que os danos causados pelos ésteres nas células das glândulas salivares e dos ovários desses ectoparasitas, aumentaram na mesma proporção que houve aumento das concentrações do produto, provocando intensa degeneração dos órgãos / Abstract: The present study brings information which shows the interference of ricinoleic acid esters extracted from castor oil (Ricinus communis) on the secretory cycle of Rhipicephalus sanguineus female ticks' salivary glands and vitellogenesis, acting directly on the feeding and reproduction processes respectively. To perform this study, host rabbits were infested with ticks, fed with regular commercial rabbit food (control-CG) and with food enriched with ester in different concentrations (treatment- TG). The salivary glands were damaged and had the cytoplasm of acinar cells altered, impairing their functioning, and the toxic substance also accelerated the degeneration of the organ as a whole. The esters interfered in the cellular secretion activity altering the composition of salivary glycoproteins, especially in the glandular cells of acini II. The effect of the esters in the vitellogenesis was observed in the oocytes of ticks belonging to the treatment group (TG), whose germinative cells presented cytoplasmic alterations, inhibition of the development of oocytes I and II for advanced stages (IV and V) and interference in the maturation of oocytes V. In addition, spermatozoa were not observed in the interior of the ovaries ampoules, confirming the acaricidal potential of the esters. It was also demonstrated that the damages caused by esters in the salivary glands cells and ovary cells of these ectoparasites increased in the same proportion of the increase in the concentrations of the toxic product, causing intense degeneration of the organs / Mestre
