Essential oil-containing solutions (mouthwashes) preserve dental enamel with releasing low Ca and P concentrations without morphology alterations: an study.

The use of natural products such as essential oils has been suggested due to their promising pharmacological effects and economic viability. This study aimed to determine hydrogenic potential (pH), titratable acidity (TA), and ion concentrations of five solutions containing essential oils (EO), when used as a EO-containing solutions, and evaluate ion concentrations, enamel surface loss, and morphology alterations in enamel. The pH, TA, calcium (Ca), potassium (K), and sodium (Na) concentrations of five EO-containing solutions were measured.

[Evaluation of small intestine and mesenteric lymph nodes of dogs (Canis familiaris) experimentally infected by Sarcocystis cruzi (Hasselman, 1923) Wenyon, 1926 (Apicomplexa: Sarcocystidae)].

Species of the genus Sarcocystis are considered as important parasites of domestic animals. Dogs are considered as definitive host for a variety species of Sarcocystis, when they fed on intermediated host tissues cysts shed sporocysts in their feces. Grinded bovine cardiac muscles, positive for Sarcocystis cruzi was given to two puppies free of coccidia.
