The metabolism of radioiodinated IgG was studied in 20 patients with rheumatoid arthritis and 11 normal controls using autologous IgG and homologous IgG pooled from normal donors. Fractional catabolic rates in the controls were 4.44% of the autologous- and 4.29% of the homologous-labeled protein per day. The corresponding rates in the rheumatoid patients were 9.67% of the autologous- and 8.64% ...

We investigated the feasibility of generating cytotoxic T cell clones against autologous human melanoma cells using a melanoma cell line (VIP) and a spontaneously transformed autologous fibroblast line (VIP-F:T). Cytotoxic lymphocytes (CL) generated against the VIP melanoma cells in one-way mixed lymphocyte-tumor cell interactions were expanded in interleukin 2 for 2 wk. The expanded CL were cl...

nowadays, cell -based and tissue engineered products have opened new horizons in treatment of incurable nervous system disorders. the number of studies on the role of schwann cells (sc) in treating nervous disorders is higher than other cell types. different protocols have been suggested for isolation and expansion of sc which most of them have used multiple growth factors, mitogens and fetal b...

post-remission treatment in patients with acute myeloid leukemia is still controversial. one potent choice for patients with no donor available is autologous stem cell transplantation. the median follow-up period was 18 months and the median age was 26 years old. in the review of 116 recently diagnosed aml patients (except aml- m3) who underwent autologous stem cell transplantation, 72.4% of pa...

BACKGROUND The possibility that autologous NK cells could serve as an effective treatment modality for solid tumors has long been considered. However, implementation is hampered by (i) the small number of NK cells in peripheral blood, (ii) the difficulties associated with large-scale production of GMP compliant cytolytic NK cells, (iii) the need to activate the NK cells in order to induce NK ce...

Introduction: We aimed at evaluating the clinical, laboratory and echocardiography effects of intracoronary administration of autologous bone marrow stem cell transplantation in different clinical entities of chronic Heart Failure (HF) patients.   Methods: This procedure was carried out during an interventional study conducted in the Cardiology department from JAN 2012 to APR 2013. The HF ...

Background: Some types of implants used for orbital implantation have side effects and complications. In this study we have evaluated beta-tricalcium phosphate (ß-TCP: ChronOS) granules as an orbital implant. Methods: Eighteen rabbits randomly allocated to four groups. Right eye enucleation performed in groups I to III followed by filling with autologous bone particles (n=5), a mixture of autol...

One explanation for why downstream gonadotropin protocol changes during IVF commonly arrive too late to have significant effects is that embryo development actually begins during oogenesis. Thus, efforts to modify the chromosomal status of blastocysts must address the ovarian milieu well in advance of follicular recruitment. A 42 years old woman with primary infertility of 3 years duration atte...
