RESUMO
This study analyzes the lipid composition and the oxidative stability of oils of Sapindaceae and Meliaceae seeds. The oil content ranged from 14.7% (Guarea guidonia) to 30.1% (Allophylus puberulus and Paullinia elegans). Ten fatty acids were identified in seed oils. Guarea guidonia seeds accumulated mainly oleic (44.9%) and linoleic (24.1%) acid, whereas the unusual gondoic and paullinic acids were identified in A. puberulus (15.8%; 8.9%) and P. elegans (14.4%; 44.2%), respectively. The oil of P. elegans had the highest oxidative stability (16.2 h.). Tocopherol predominated in A. puberulus (10.4 mg/100 g) and tocotrienol predominated in G. guidonea and P. elegans (2.6 mg/100 g). The vitamers α-tocopherol, γ-tocopherol, and γ-tocotrienol were found in the studied oils. ß-carotene was predominantly detected in the oil of A. puberulus seeds (22.4 µg/g). Guarea guidonia seed oil has a high potential in food due to richness in essential fatty acids. In turn, A. puberulus and P. elegans oils could be suggested for other industrial purposes (e.g., biodiesel, varnishes, paints, soaps, or oleochemicals) due to their content of long-chain fatty acids.
RESUMO
A foreign body in the esophagus is usually removed by endoscopy. An elder man entered the emergency room dyspneic and dysphagic. A chest X-ray showed that he had a table fork stuck in the upper esophagus. An endoscopist tried to remove it without success. After bilateral block of the superior laryngeal nerve, transtracheal injection, topical anesthesia of the mouth, and sedation, an awake laryngoscopy was carried out. Pushing the laryngoscope into the opening of the esophagus the fork was seen and extracted by the anesthesiologist. This case focuses on the role of the anesthesiologist in the removal of esophageal foreign bodies.
