We obtained serum bone markers and other relevant endocrine assays on 5 patients with osteonecrosis of the jaw (ONJ). The assays were C-telopeptide, N-telopeptide, bone-specific alkaline phosphatase, osteocalcin, intact parathyroid hormone, T3, T4, TSH, and Vitamin D 25 hydroxy. Diagnostic criteria for ONJ were those formulated by the American Association(More)
PURPOSE To determine whether any abnormality in serum bone markers is related to bisphosphonate-induced osteonecrosis of the jaw. MATERIALS AND METHODS We obtained serum bone markers and other relevant endocrine assays on 7 patients with osteonecrosis of the jaws (ONJ). The assays were C-telopeptide, N-telopeptide, bone specific alkaline phosphatase,(More)
To demonstrate the ectopic production of pregnancy-specific beta 1-glycoprotein (PSbetaG) by a nontrophoblastic tumor, the in vitro secretion of this glycoprotein was evaluated in an hCG-producing ovarian cystadenocarcinoma cell line maintained in long term cell culture. Parallelism was demonstrated between the immunoreactive material present in the tissue(More)
The report deals with studies of the penetration of gamma-globulin I131 of rabbit antibrain sera into the different brain areas of intact and sensitized rats and into the placenta of embryo tissues. It was demonstrated that lebeled I131 gamma-globulin containing antibodies to homo- and heterologous brain may in a small amount penetrate from the blood into(More)
The accumulation and distribution of phosphorus radioisotope was studied in different brain areas of rats. These rats were desensitized by antigens of a whole homologous brain and its separate structures. A certain general tendency towards an accumulation of the brain phosphorus was detected after neurosensitization. Besides, in sensitization by separate(More)
The comparison of 32 immature infants with mental retardation of various degree (based on the results of clinical, immunological and biochemical examinations) with full-term infants with analogous pathology showed in the former group a high incidence (82.8%) of cerebral antibodies to antigens of the homo- and heterological brain in the complement(More)
The study of immunoglobulin levels and neuroimmune processes in younger schoolchildren with slightly retarded intellectual development revealed the deficiency of immunoglobulin A (either alone or in combination with other types of immunoglobulins). The neuroimmune processes identified were characterized by the presence of brain antibodies predominantly(More)
