We experienced an autopsy case of a death associated with ingestion of liquid detergent. The deceased was an 82-year-old woman who was found dead in her bed room. Autopsy revealed corrosive changes of the mucosal surfaces of the lung. The larynx, trachea and stomach contained mucoid matter with abundant froth. Toxicological investigations detected polyethylene glycol in the bronchus, blood and ...
Febrile neutropenia is common in children with leukemia. Mucous membrane and skin are most common portals of entry for microorganisms in these patients. The aim of the present study was to find the prevalence of mucocutaneous findings infebrile neutropenic leukemic children. The authors prospectively examined children with fever with neutropenia in acute leukemia, aged 1-15 years, who were admi...
The airway mucosa is lined by a continuous epithelium comprised of multiple cell phenotypes, several of which are secretory. Secretions produced by these cells mix with a variety of macromolecules, ions and water to form a respiratory tract fluid that protects the more distal airways and alveoli from injury and infection. The present article highlights the structure of the mucosa, particularly ...
The mechanism of transmission infection is a way moving an infectious agent from infected organism to susceptible one. Each disease has its own characteristic pathway pathogen transmission, which was formed during evolution preserve the as species. includes three phases: excretion host into environment, presence in introduction new organism. main for transmitting coronavirus air-droplet (or air...
For more than a century, antibody has been used for passive parenteral immunization against viral and bacterial pathogens. This approach has been successful for prevention of viral respiratory infection and has led to testing of intranasal or aerosol delivery of antibody to passively immunize the respiratory tract mucosal surface. Mucosal delivery may be advantageous because it allows the antib...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
Introduction Perforation of maxillary sinus mucous membrane is of the most prevalent complication during open sinus lift surgery. Moreover, such complication can usually be managed by an absorbable membrane. As far as absorbable membranes are concerned, decellularized maxillary sinus mucous membranes, which is an extracellular matrix, can be used as a biologic scaffold and insulating membrane ...
Air pollution is composed of a particulate phase and a gaseous phase. The particulate phase, consisting of dust and aerosols, is the vehicle of toxic pollutants, transporting them into the respiratory tract. The irritants (sulphur dioxide, nitrogen oxides, aldehydes, and hydrocarbons) are the most important pollutants as regards health; the mucous membranes of the eyes and the respiratory tract...
Unprepared mice given intranasal inoculations of certain strains of pneumococci develop pneumonia. The proportion of inoculated mice which will show the pneumonia at autopsy is dependent upon the strain and type of organism and the breed of mice used. It has been shown that, with the technique employed, the pneumococci reach the lower respiratory tract and alveoli almost immediately; moreover, ...
