adenocarcinoma of the stomach was the leading cause of cancer-related death worldwide through most of the 20th century. usual presentations of gastric cancer include anorexia, epigastric pain or discomfort and weakness. rarely, patients present with unusual clinical manifestations. in this article, we report two cases with uncommon presentations of gastric adenocarcinoma. the first patient was ...

introduction bacillus calmette-guérin (bcg) vaccine, a live attenuated mycobacterium bovis strain, is administrated to all newborn infants in endemic regions according to the current world health organization (who) recommendation. case presentation we report a 10-month-boy who was a known case of severe combined immunodeficiency (scid) admitted with multi-focal fusiform painful swelling in his ...

I N EARLIER REPORTS it was demonstrated that the injection of suspensions of normal bone marrow from the same species would prevent the death of animals exposed to total body irradiation. Data indicating protection are available on mice (I), rats (2), hamsters (3), and guinea pigs (I). The results obtained with bone marrow suspensions in irradiated rabbits and dogs were equivocal (49. 5>* Altho...

We previously established 4T1E/M3 highly bone marrow metastatic mouse breast cancer cells through in vivo selection of 4T1 cells. But while the incidence of bone marrow metastasis of 4T1E/M3 cells was high (~80%) when injected intravenously to mice, it was rather low (~20%) when injected subcutaneously. Therefore, using 4T1E/M3 cells, we carried out further in vitro and in vivo selection steps ...

Background & objective: Introduction: First detection of any solid tumour as metastatic deposits in bone marrow directs clinicians to start searching for the primary tumour. Detection of bone marrow metastasis determines the stage of the malignancy, prognosis, mode of treatment, chemotherapeutic response and follow-up in case of relapse. The aim of the current...

The injection of naked plasmid DNA directly into the muscle cells of mice has been shown to induce potent humoral and cellular immune responses. The generation of a cytotoxic T lymphocyte (CTL) response after plasmid DNA injection may involve the presentation of the expressed antigen in the context of the injected myocytes' endogenous major histocompatibility (MHC)-encoded class I molecules or ...

Graft versus host disease (GVHD) may be abrogated and host survival prolonged by in vitro depletion of T lymphocytes from bone marrow (BM) prior to allotransplantation. Using a mouse anti-rat pan T-lymphocyte monoclonal antibody (OX19) bound to monosized, magnetic, polymer beads, T lymphocytes were removed in vitro from normal bone marrow. The removal of the T lymphocytes was confirmed by flow ...

The CC-chemokine eotaxin is a potent eosinophil chemoattractant that stimulates recruitment of eosinophils from the blood to sites of allergic inflammation. Mobilization from the bone marrow is an important early step in eosinophil trafficking during the allergic inflammatory response. In this paper we examine the potential of eotaxin to mobilize eosinophils and their progenitors from bone marr...

We established inducible osteonecrosis in a rabbit serum sickness model. Osteonecrosis with marrow necrosis could be induced by the intravenous injection of horse serum in two doses separated in time by a period of three weeks. In this model, osteonecrosis could be successfully produced in rabbit femoral metaphysis. The incidence of marrow necrosis was 45% (9 of 20 rabbits) and trabecular necro...
