The faculty member of Mashhad University of Medical Sciences stated: With the implementation of Methylene Blue research project in clinical trials of phase 2 and 3 in Shariati and Imam Reza (AS) hospitals in Mashhad, excellent results were obtained in the treatment of patients, which led to rapid discharge from the hospital and Mortality rate decreased.Dr. Dariush Hamidi Alamdari, the leader of the research project for the treatment of coronary heart disease using methylene blue (approved by Mashhad University of Medical Sciences) in an interview with WebDA, described methylene blue as a very safe drug and stated: This drug is for patients with meth. Hemoglobin is sought after for some poisoning and the blood oxygen in them is reduced and is used for treatment. In methemoglobin, the transfer of oxygen by iron is not done three times positively for hemoglobin in red blood cells, and methylene blue converts three times positive iron to positively, and then oxygen can be bound to iron twice, which raises the oxygen level of the blood. . The faculty member of Mashhad University of Medical Sciences stated: During my studies on patients and wounds, I noticed the effect of methylene blue in increasing oxygen delivery in tissues and led to methylene blue being a suitable candidate for increasing oxygen delivery in coronary arteries. It can be prescribed to treat these patients. The faculty member of Mashhad University of Medical Sciences stated: Due to the fact that corona patients have low blood oxygen and have difficulty breathing, this drug can help increase blood supply to these patients, submit a research proposal to the university and Based on scientific documents, it was approved by the university and was used as a treatment for Covid-19 patients in Shariati Hospital, Imam Reza Hospital and Ghaem Hospital, and was able to accelerate the process of discharging patients. Clearly reduce mortality rates.The faculty member of the Department of Clinical Biochemistry of Mashhad University of Medical Sciences added: "The article related to this proposal has been published in the European Journal of Pharmacology and another article has been accepted as Clinical and Translational Investigation and several other articles have been extracted from this proposal." They discuss the very positive therapeutic results obtained through treatment with methylene blue
