Cardiovascular effects of ionic monomeric, ionic dimeric and non-ionic contrast media. Effects in animals on myocardial contractile force, pulmonary and aortic blood pressure and aortic endothelium

T Almén, P Aspelin


Three different types of contrast media, monomeric ionic, dimeric ionic and monomeric non-ionic, were tested and compared concerning their toxicity on three experimental models: I. Pulmonary artery and aortic pressure after contrast medium injection into the right atrium in rabbits: II. Ventricular contractile force and heart rate after perfusion of the coronary arteries on the isolated rabbit heart: III. Aortic endothelium of rats. Non-ionic contrast medium was, in all three experiments, less toxic than monomeric ionic; thus it caused less rise in pulmonary artery pressure (I) and caused less reduction in ventricular contractile force and heart rate (II) and caused less damage on aortic endothelium of rats (III). The non-ionic contrast medium also gave less toxic reaction in two (I and II) of the three models compared to the dimericionic contrast medium. In experimental model III there was no difference between these two agents. Also, the dimeric ionic contrast medium caused less toxic reactions in all three models than the monomeric ionic contrast medium.

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.

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.

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.

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.

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.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
