Delayed-type hypersensitivity reaction in the lungs of guinea pigs due to potassium dichromate

Abstract

Potassium dichromate was inhaled by guinea pigs previously immunized by potassium dichromate until strong positive patch tests were obtained. No obvious respiratory changes were noted during and after inhalation. Histologically, however, mononuclear cells infiltrated the interstitial spaces in large areas of the lung, producing considerable thickening of the alveolar spaces in 24 to 48 hr after inhalation. Polymorphonuclear cells were predominant initially. These changes were similar to the delayed-type hypersensitivity reaction in the lung elicited by the inhalation of purified protein derivative (PPD) in the guinea pigs immunized by an injection of dry-killed tubercle bacilli. A less marked reaction was observed in guinea pigs passively sensitized with peritoneal exudate cells and lymph node cells. Consequently, the pulmonary changes were thought to be elicited by delayed-type hypersensitivity reaction due to a simple chemical. The clinical implications of delayed-type hypersensitivity reaction in the lung due to simple chemicals are discussed.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.
