Ethyleneglycol, detected in the affected people`s blood in Dagestan chemical laboratory of forensic medical examination, hardly can be the reason of mass illness, considers Chechnya`s Deputy Public Health minister Zaur Musluyev. "The discovered substance, corresponding to Ethyleneglycol requires additional examination in view of little number of samples received", noted he. "It`s too early now to make the definite conclusion, besides this substance is a part of many very good medications of perfect quality, produced abroad. That`s why it can`t produce such a clinical effect", he added.
