Expression Of The Tumour Suppressor Gene P53 In Odontogenic Cysts, Ayla Özveren, Can Tuskan, Mehmet Yaltirik, Beli̇r Atalay, Gülçi̇n Erseven

Turkish Journal of Medical Sciences

The protein p53 seems to be related to the suppression of cell proliferation. Positive tissues appear to have a higher proliferative activity than negative tissues. Mutation of the p53 tumour suppressor gene has been demonstrated in a large proportion of human head and neck tumours, although no formal evidence of functional aberration has been shown p53 may have importance during the early stage of malignancy. The aim of this study was to evaluate the role of the p53 tumour suppressor gene in the pathogenesis of odontogenic cysts. Expression of abnormal p53 protein is a widely recognised marker of malignancy. Expression …

Experimental toxoplasmosis was induced in rabbits using different routes. A total of 42 animals were used; 36 of them were in the experimental groups and the other six comprised the control group. In addition, five guinea pigs were used for preparing hyperimmune sera against Toxoplasma gondii. The Ankara strain was inoculated intravenously (group I, n: 12), intraperitoneally (group II, n: 12) and intradermally (group III, n: 12) into the rabbits. Group IV animals were kept as controls (n: 6). Clinical and macroscopical findings varied according to the routes of inoculation and organs affected. Microscopically, multifocal necrosis with T. gondii tachyzoites …
