Protective effect of a splenic extract in mice with endotoxemia

The Journal of Trauma
C R SpillertK M Jain


We have previously described the isolation of a lipoidal splenic extract (LSE) that demonstrated a variety of hematologic effects including inhibition of platelet aggregation both in vivo and in vitro. Since endotoxin causes platelet aggregation and microembolism the protective effect of LSE in endotoxemia was examined in the present study. Both young and elderly Swiss mice given LSE 2--3 hours before endotoxin challenge showed a statistically significant increase in survival compared with saline-treated controls. However, no significant improvement in survival was noted when LSE was administered at the same time as endotoxin. These results add further support to the role of the spleen in the control of infection.

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.
