Normal and on Polio Myelitis Virus Infected Tissue Cultures
نویسنده
چکیده
Es wurden zwei verschiedene Thymo-nucleodepolymerasen viskosimetrisch in Gewebekultur nachgewiesen. Bei beiden Fermenten beobachteten wir eine Aktivitätsabnahme nach Infizierung der Gewebekultur mit Poliomyelitis-Virus. In gleicher Weise hemmt virushaltige Flüssigkeit aus Gewebe kultur die Aktivität kristalliner DNA-se von Kalbspankreas und die Aktivität der DNA-sen im Affennieren-Homogenat. Die Fermenthemmung im Organbrei war am größten. Die Versuche zeigen, dali die Hemmwirkung in den 3 verschiedenen Systemen (infizierte Gewebekultur, kristallisierte DNA-se, ungereinigter Organextrakt) ähnlicher N atur sind. Sie scheint von spezifischen und allgemeinen Inhibitoren verursacht zu sein. Während des durch die Viren bedingten Zellzerfalles beobachteten wir eine geringe temporäre Zunahme der DNA-ase-Aktivität; dann folgte die irreversible Abnahme. Die theoretische Bedeutung der Befunde wurde besprochen.

The polio vaccine: a critical assessment of its arcane history, efficacy, and long-term health-related consequences
Polio (poliomyelitis) is a potentially dangerous viral ailment. To combat this disease, researchers developed two polio vaccines (inactivated and live) grown in cultures made from monkey kidneys. Beginning in the 1950s, these vaccines were administered to millions of people in the United States and throughout the world. Officially, the polio vaccine is considered safe and effective, and has bee...
متن کاملFine Structure of Changes Produced in Cultured Cells Sampled at Specified Intervals During a Single Growth Cycle of Polio Virus
Primary suspended cultures of rhesus monkey kidney cells were infected with poliomyelitis virus, type 1 (Brunhilde strain). The release of virus from these cells over a one-step growth curve was correlated with their change in fine structure, as seen in the electron microscope. Most of the cells were infected nearly simultaneously, and morphological changes developed in the cells were sufficien...

Widespread occurrence of H9N2 low pathogenic avian influenza (LPAI) viruses in many Asian countriesduring the past decade has resulted in the need for evaluation of the pathogenesis of H9N2 virus infection. In this study, tissue tropism and dissemination of A/Chicken/Iran/772/1998(H9N2) virus throughout the body of broiler chickens were investigated. The clinical signs, gross lesions and antibo...

Acute Flaccid Myelitis (AFM), a polio-like paralysis in children no older than 21, has recently reemerged and increasing numbers of such cases have been reported worldwide since 2012. Accurate and early diagnosis of this condition could help with better management of the disease. A 9- year- old girl with chief complaint of headache, fever and vomiting was subsequently affected by an acute...
متن کاملExtensive myelitis after oral polio vaccination: MRI features.
A 7-year-old boy presented with fever and ataxia 20 days after oral polio vaccination. Magnetic resonance imaging showed extensive myelitis, involving both anterior and posterior horns of the gray matter. Complete posttreatment recovery was evident. Postvaccinal myelitis after oral polio vaccination, of either infectious or immune mediated etiology, is very rare entity that should be promptly r...
