Forty-five mixed breed dogs were evaluated for the presence and extent of periodontal disease. Histopathology was performed on samples of lung, myocardium, liver, kidney, tonsil, spleen, submandibular lymph node and tracheobronchial lymph node. Mitral valves were evaluated grossly. Statistical analysis was used to determine if there was a relationship between the extent of periodontal disease and histopathologic changes in the tissues examined. In the forty-five dogs studied, an association was found between periodontal disease and histopathologic changes in kidney, myocardium (papillary muscle), and liver.

This study examines the fate of extravasated plasma in inflammatory stimulus-challenged large tracheobronchial airways of ketamine-xylazine-anesthetized guinea pigs. Entry of plasma tracers into the airway lumen was determined by a validated noninjurious airway lavage technique. Removal by airway lymphatics was assessed by tracheobronchial lymph node levels of plasma tracers. Mucosal challenges with histamine (5 nmol), bradykinin (5 nmol), capsaicin (0.4 nmol), or allergen (ovalbumin, 3 pmol) increased the appearance of a plasma tracer (131I-labeled albumin previously injected intravenously) in the airway lumen within 10 min (10–20 times control; P < 0.001), whereas the contractile agent carbachol (8 nmol) was without exudative effect. The mediators were without effect, and capsaicin and allergen only slightly increased the lymph node level of plasma exudation tracer (1.5 times control; P < 0.05). Hence, removal via the lymphatic route of plasma macromolecules may be negligible in the acute and postacute phases of an airway exudation response. Experiments were also carried out with luminally applied macromolecular tracers. These were absorbed from the mucosal surface into the circulation, but a small portion was also transported to the lymph nodes, demonstrating the interconnections between the mucosa and the sampled nodes. Only capsaicin produced an increased node level of absorption tracer. Immunohistochemistry showed that the tracheobronchial tissue and lymph nodes are endowed with nerve fibers containing substance P, the release of which may have mediated lymph transport, vascular, and exudative effects of capsaicin in the present studies.(ABSTRACT TRUNCATED AT 250 WORDS)
