Large scale programs for the control of poliomyelitis through the use of active immunization can be said to have started, both in the United States and elsewhere, in 1955. This step marked the end of a 40-year period in which experimental efforts to vaccinate against poliomyelitis had been repeatedly tried. As early as 1910, Dr. Simon Flexner, the Director of the Rockefeller Institute, and at t...

1. A neurotropic murine virus was isolated by passing poliomyelitis virus (SK strain) from the monkey to cotton rats and white mice. 2. The murine virus has been grown in tissue culture consisting of embryonic mouse brain in ox serum ultrafiltrate. 3. The symptoms and lesions produced by the murine infection compare in all respects with those of poliomyelitis in monkey and man. 4. The murine vi...

BACKGROUND Total hip arthroplasty (THA) for poliomyelitis is a problematic procedure due to difficulty in positioning the cup of the prosthesis in the true acetabulum and the risk of dislocation after THA due to the low muscle tone. METHODS We herein present a case of bilateral hip pain with a history of poliomyelitis. Radiograph showed bilateral hip osteoarthritis caused by hip dysplasia due...

The study of the epidemiology of poliomyelitis has been complicated by the high ratio of inapparent to clinically recognizable infections and, until recently, by the lack of availability of practical laboratory methods to detect infected persons. A number of normal population groups have been surveyed for virus-neutralizing antibodies, which persist for many years, if not for life, and allow on...

Poliomyelitis viruses have been immunologically grouped into three types, Brunhilde, Leon and Lansing. Although much of effort has been devoted to isolate poliomyelitis virus in Japan1-2), little is revealed concerning the immunological property of the strains isolated3). After World War II, the existence of poliomyelitis virus •gLansing•h strain in Japan was suspected from the results obtained...

OBJECTIVES To determine the magnitude of poliomyelitis and assess its epidemiological features. DESIGN A cross-sectional community based, house-to-house survey. SETTING Six urban and ten rural villages in Gondar Zuria district, north-western Ethiopia. SUBJECTS Twelve thousand children aged 1-15 years residing in the randomly selected areas were enrolled in the study to identify children w...

ALTHOUGH cardiovascular collapse had previously been noted in patients with acute poliomyelitis,' 2 Baker and his colleagues3' 4first indicated that this lethal symptom complex is a relatively common feature of bulbar poliomyelitis. They examined in detail the medulla of 80 cases dying of poliomyelitis and concluded that this syndrome was due to involvement of the large cells in the ventromedia...

The Epidemiology of poliomgelitis has been investigated in our country Pasteur Institute; the incidence of Poliomgelitis, after the age of 4 years i's rare, in Iran.  Passive antibody of maternal origin do not interfere with production of active antibody after immunization.  Inactivated Polio Vaccine (salk) has been effective in reducing the incidence of poliomge­litis by approximately 90 per ...

The green African monkey, Cercopithecus aethiops sabaeus, has been infected with experimental poliomyelitis after feeding artificially contaminated food. This species is also highly susceptible to intracerebral, intranasal, and intraabdominal inoculations. In one experiment with a human stool from a case of poliomyelitis, Cercopithecus was more susceptible to intranasal and to intraabdominal in...
