RESUMEN
Among the biological properties of Rosmarinus officinalis Linn. (rosemary), the infusions and ethanolic extracts are popularly used to treat gastrointestinal disorders. However, the effects of these extracts on the gastric motility are unknown. Here, we evaluated influence of the rosemary extracts on gastric motility and its chemical composition. Forty-eight female Wistar rats with food restriction for 12 h were made into eight experimental groups (n=6, each) and given oral treatments (1 mL) of ethanolic and aqueous extracts at the doses of 125, 250 and 500 mg/kg, and distilled water (control) and metoclopramide (2 mg/kg, intramuscular). After one hour, five metal spheres (1 mm) were administered with barium contrast. A series of radiographs were taken every hour for six hours. Significant differences were shown in the gastric emptying of the metal spheres within three hours among the extracts and the control groups. By high-performance liquid chromatography (HPLC), both extracts presented kaempferol, carnosic acid and rosmarinic acid as major compounds, which would influence in the higher time for emptying. This study showed that the rosemary extracts increased the gastric emptying time in healthy rats, suppressing the gastric motility, and may be useful in treating digestive disorders, like diarrhea.
RESUMEN
A esporotricose é uma micose subcutânea causada pelo fungo dimórfico Sporothrix schenckii. Este artigo descreve o primeiro caso de esporotricose óssea e cutânea, em canino, na cidade de Pelotas, Rio Grande do Sul. O animal apresentava lesões ulceradas e crostosas, há aproximadamente três anos no plano nasal e membro torácico direito, dispnéia e apatia. Para confirmação do diagnóstico, foram realizados exames micológico, histopatológico, radiológico e hematológico. O animal foi tratado durante três meses com 10mg/kg de itraconazol,por via oral, obtendo-se a cura das lesões. Este estudo alerta clínicos de pequenos animais para a ocorrência desta micose em caninos na região de Pelotas, RS.
The sporotrichosis is a subcutaneous mycosis caused by dimorphic fungus Sporothrix schenckii. This article describes the first cutaneous and osseous sporotrichosis case in canine in the Pelotas city, Rio Grande do Sul. The animal presented crusts and ulcerated lesions,approximately the three years in the nasal plan and right hind-foot,dispneic and apathy. Mycological, histopathological, radiological and hematological diagnosis was realized. The animal was treated by three months with itraconazole, administered orally at a dosage of 10mg/kg, until lesions disappeared. This study alert small animals clinicians for the occurrence of this mycosis in dogs in the region of Pelotas, RS.
