- Bookby Robert W. Baloh.Summary: Despite the rapid advances in medical science, the majority of people who visit a doctor have medically unexplained symptoms (MUS), symptoms that remain a mystery despite extensive diagnostic studies. The most common MUS are back pain, abdominal pain, headache, fatigue, and dizziness. This book addresses the obstacles of managing people with MUS in our modern day society from both a historical and contemporary perspective. Most MUS are psychosomatic in origin, caused by a complex interaction between nature and nurture, between biological and psychosocial factors. Psychosomatic symptoms are as real and as severe as the symptoms associated with structural damage to the brain. Unique and concise, the book explores the biological and psychosocial mechanisms, the clinical features, and current and future treatments of common MUS. Exploring the unsolved in an accessible manner, Medically Unexplained Symptoms invokes the methodologies of medical science, history, and sociology to investigate how brain flaws can lead to debilitating symptoms.

Treatment of Psychosomatic Symptoms. - ArticleHeiman C, Miller CG.J Bacteriol. 1978 Aug;135(2):588-94.Mutants of Salmonella typhimurium lacking protease II, an endoprotease with trypsin-like specificity, have been isolated. These mutants can be identified by using the chromogenic substrate N-methyl-N-p-toluenesulfonyl-L-lysine beta-naphthyl ester to screen colonies growing on agar for the presence of the enzyme. All of the mutations isolated map at locus tlp (typsin-like protease) which is cotransducible (approximately 1%) using phage P1 with tre (trehalose utilization) at approximately 58 min on the Salmonella map. Double mutants lacking both protease I and protease II have been constructed. These strains grew normally. They were able to degrade abnormal proteins and to carry out protein turnover during carbon starvation at the same rate as the wild type.
