ELECTROTHERAPY IN THE TREATMENT OF PATIENTS AFFECTED BY RABIES: EXPERIMENTS CONDUCTED AT THE “MAGGIORE” HOSPITAL OF MILAN IN 1865 [PDF]
During the nineteenth century, the scientific context of rabies treatment was weak due to the lack of the literature on specific nosology of the rabies disease, and unspecific and ineffective therapy approaches.
