Abstract

The present work was undertaken to study the effects of a deproteinized extract of calves' blood (Solcoseryl) on developing granulation tissue in rats. Cylindrical hollow viscose cellulose sponge implants were used as an inductive matrix for the growth of granulation tissue. In the first, sham group the implants were treated daily by withdrawing 1 ml of wound fluid from the central dead space of the implant and then re-injecting the fluid. In the second, experimental group the aspirated wound fluid was replaced by a corresponding volume or Solcoseryl. Analyses of wound fluid and granulation tissue were carried out 4, 10 and 21 days after implantation. A statistically significant increase of granulation tissue hemoglobin (+21%) was observed at 10 days in the Solcoseryl group as compared with the sham-treated rats, indicating an enhanced capillary ingrowth. Concurrently, the mean amount of DNA in the Solcoseryl-treated tissues was elevated by 48% over the level of the sham-treated group, demonstrating an augmented cellularity of granulation tissue. At 21 days the mean amount of collagen hydroxyproline of the Solcoseryl group was 31% above the level measured in the sham-treated animals. PO2, PCO2 and pH in the wound fluid and the ...Continue Reading

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.

Social Learning

Social learning involves learning new behaviors through observation, imitation and modeling. Follow this feed to stay up to date on the latest research.

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.
