Presence of Phospholipidic Lamellar Bodies On the Mucosa of Rabbit Eustachian-tube - Ultrastructural Aspects
Electron microscopy of the rabbit eustachian tube showed the presence of osmiophilic lamellar bodies in the cytoplasm of secretory cells and of osmiophilic free lamellar membranes in the lumen of tubal glands or above the epithelium. Similar structures have been reported in other parts of the respiratory system and in the pulmonary alveoli. The functional significance of these morphological observations is suggestive of a surface-tension-lowering effect on the mucosal lining layer of the eustachian tube and of a possible relationship to the phospholipid surfactant of the lung

Use of Serum Markers In the Diagnosis and Management of Laryngeal-cancer
Many neoplastic diseases are reported to be accompanied by the presence or associated with an increase in biological substances identified as tumour markers. The most common markers implicated in head and neck cancers are CEA, TPA, LASA, SCC, CA 19-9, and ferritin. These markers (except SCC) were evaluated in 50 patients with a laryngeal carcinoma, in 20 patients with benign lesions, and in 20 healthy subjects. The results show for each marker assayed the following sensitivity values (true positives): CEA, 10%; CA 19-9, 30%; TPA, 30%; LASA, 90%; ferritin, 60%. Specificity (true negatives) was as follows: CEA, 85%; CA 19-9, 99.4%; TPA, 98%; LASA, 99.8%; ferritin, 97%. LASA and ferritin seem to be the most suitable markers for patient monitoring because of their higher sensitivity in all phases of cancer disease
[Determination of sialic acid in cancer of the upper aero-digestive tract].
The determination of serum lipid sialic acid (LSA) in subjects with laryngeal and oral cavity carcinomas demonstrated an important correlation between the presence of carcinoma and tumor marker elevation. 90% of positivity has been found in 60 cases of laryngeal carcinoma; 100%, on the contrary in 19 cases of oral cavity. The authors affirm the importance of LSA as a tumor marker, in particularly in monitoring patients submitted to surgical excision
