Alterations in the rat kidney associated with sodium saccharin feeding: a scanning electron microscopic study

Toxicology Letters
T D Miller, S M Cohen

Abstract

Sodium saccharin has previously been demonstrated to induce hyperplasia of the urothelium of the rat kidney pelvis. It was fed as 5% of the diet to male F344 rats for 18 weeks. In the present experiment, scanning electron microscopy (SEM) was utilized to detect early morphologic changes. Pleomorphic microvilli (PMV) were observed in all four sodium saccharin-fed rats, located on cells at the junction of the papilla and pelvis. PMV also occurred at the papilla-pelvic junction in three of the ten control rats, but the affected area was smaller and the PMV exhibited less severe atypia.

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.

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.
