Abstract

Propylhexedrine, the active ingredient in Benzedrex Inhalers, is extracted from the wicks of the inhalers by drug abusers for intravenous injection to provide a "desirable high." Six representative cases treated over a one-year period are presented to exemplify the potential for soft tissue injury. Because the actual constituents of the injected material prepared from the inhalers were not established, solutions were prepared from Benzedrex Inhalers according to the formula provided by one of the patients. The extract was then subjected to vigorous qualitative and quantitative analyses; the presence of essentially pure propylhexedrine hydrochloride was confirmed in varying concentrations. To examine the progression of injury following injection of the prepared extract, the ears of 12 New Zealand white rabbits were injected either intra-arterially or subcutaneously. The opposite ear of each rabbit served as a control. Both clinical and pathologic observations demonstrated injury consistent with intense local vasoconstriction. Injury did not appear to relate to impurities in the solution or other embolic phenomena. Finally, the laboratory findings are discussed with regard to the clinical examples. In sum, the insult to tissue fr...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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. Here is the latest research.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

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.
