Influence of stroma-free hemoglobin solution on renal function in dogs

Abstract

In the presented series of experiments, stroma-free hemoglobin solution (SFHS) was used as a perfusate for extracorporeal perfusion of kidneys and for exchange transfusion. It was shown that SFHS was adequatly oxygenated both as perfusate during the extracorporal perfusion and in the lungs after the blood exchange. Furthermore, there was provided evidence that oxygen was being transported and released in the tissues. Histologic examination of the kidneys demonstrated hemoglobin casts in the glomerules. Most of them were seen after extracorporal perfusion of isolated kidneys, less frequently after perfusion in situ and few casts were present after exchange transfusion. The cause of these depositions may be small remnants of stroma in the preparation. Furthermore it is possible, that at the beginning of the extracorporal perfusion of the kidneys the urine pH was below 6 and then a hemoglobin casts formation could occur. There were essential no changes in urine pH in the course of blood exchange. In this group were only few casts present in the kidneys.

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.

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.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. 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.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.
