Sensitization of Guinea Pigs to Chromium Compounds

Inheritance in Guinea Pigs of the Susceptibility to Skin Sensitization with Simple Chemical Compounds

It has proved possible to set up lines of guinea pigs of significantly different susceptibilities towards a compound of simple structure, namely 2:4 dinitrochlorobenzene. This provides direct evidence that the type of sensitization under discussion is influenced by heredity.

Antitussive Effect of Plantago lanceolata in Guinea Pigs

Background: Several therapeutic effects including anti-asthma and dyspnea have been described for Plantago lanceolata. In the present study the antitussive effect of this plant was evaluated. Methods: The antitussive effects of aerosols of two different concentrations of Soxhlet and macerated ethanolic extracts, codeine and saline were tested by counting the number of coughs produced due to aer...

Serological observations on patients with chromium-eczema and chromium-sensibilized guinea-pigs.

Chromium and Chromium Compounds

Chromium is present in the environment in several different forms. The most common forms are chromium(0), chromium(III) (or trivalent chromium) and chromium(VI) (or hexavalent chromium). Chromium(III) occurs naturally in the environment and is an essential nutrient that helps the human body utilize sugar, protein and fat. Chromium(VI) and chromium(0) are generally produced by industrial process...

Effect of respiratory syncytial virus on subsequent allergic sensitization to ovalbumin in guinea-pigs.

Children with acute respiratory syncytial virus (RSV) bronchiolitis often develop recurrent wheezing, asthma and allergic sensitization, but the role of RSV in the pathogenesis of these sequelae is unclear. This study examined whether RSV infection potentiates subsequent allergic sensitization, airway hyperresponsiveness (AHR) and airway inflammation induced by repeated exposures to aerosolized...
