Real-time feedback control of twin-screw wet granulation based on image analysis.

The present paper reports the first dynamic image analysis-based feedback control of continuous twin-screw wet granulation process. Granulation of the blend of lactose and starch was selected as a model process. The size and size distribution of the obtained particles were successfully monitored by a process camera coupled with an image analysis software developed by the authors.

Helicobacter pylori infection in connective tissue disorders is associated with high levels of antibodies to mycobacterial hsp65 but not to human hsp60.

Background: To investigate whether the Helicobacter pylori status influences levels of antibodies against mycobacterial heat shock protein (hsp) 65 and human hsp60 in systemic autoimmune diseases and to study the concentration of anti-H. pylori antibodies in autoimmune patients and healthy controls.

Materials And Methods: Antibodies against human heat-shock protein hsp60, mycobacterial heat-shock protein hsp65 were analyzed by ELISA.

[Clinical and immunopathological significance of chimerism in bone marrow and organ transplantations].

Chimerism is an exceptional immunogenetic state, characterized by the survival and collaboration of cell populations originated from two different individuals. The prerequisites to induce chimerism are immunosuppression, myeloablation or severe immunodeficiency of the recipients on one side and donor originated immuno-hematopoietic cells in the graft on the other. Special immunogenetic conditions to establish chimerism are combined with bone marrow transplantation, transfusion and various kinds of solid organ grafting.

Remarkably reduced transplant-related complications by dibromomannitol non-myeloablative conditioning before allogeneic bone marrow transplantation in chronic myeloid leukemia.

A non-myeloablative conditioning protocol containing dibromomannitol (DBM/cytosine arabinoside/cyclophosphamide) has been applied to 36 chronic myeloid leukemia (CML) patients followed by bone marrow transplantation (BMT) from sibling donors. Risk factors include: accelerated phase (10 patients), older age (17 patients over >40 years) and long interval between diagnosis and BMT (27 months on average). Severe mucositis did not occur.

Immunological importance of chimerism in transplantation: new conditioning protocol in BMT and the development of chimeric state.

Chimerism is an exceptional immunogenetic state, characterized by the survival and collaboration of cell populations originated from two different individuals. The prerequisits to induce chimerism are immuno-suppression, myeloablation, or severe immunodeficiency of the recipients on the one side and donor originated immuno-hematopoietic cells in the graft on the other. The pathologic or special immunogenetic conditions to establish chimerism are combined with bone marrow transplantation, transfusion, and various kinds of solid organ grafting.

[A new radiation-free conditioning in bone marrow transplantation and dibromo-mannitol therapy in chronic myeloid leukemia].

A new, radiation-free, conditioning protocol, containing the original Hungarian mitobronitol (DBM) (DBM/ cytosine arabinoside/cyclosphosphamide) has been applied to 36 chronic myeloid leukemia (CML) patients followed by bone marrow transplantation (BMT) from HLA identical sibling donors between 1990-1997. In spite of some prognostically disadvantageous factors (half of them were above 40 years, 10 out of 36 patients were in accelerated phase, the disease history was longer than 2 years in average) the overall survival (30/36) and the leukemia free survival rate (26/36) were in accordance with the best international results. Transplantation-related toxicity was remarkably reduced in comparison to bone marrow transplantation performed by total body irradiation/cyclophosphamide (TBI/Cy) or busulphan/cyclophosphamide (Bu/Cy) conditioning protocols.

[Transfusion problems in liver transplantation].

Requirement of blood supplementation is especially high in liver transplantation. Authors demonstrate the quantity and quality of blood and blood preparates used in the Transplantation and Surgical Department in Budapest during liver transplantation. Praxis of transfusion and the mode in the sustain of coagulation are shown.

[Intrauterine management of Rh-alloimmunization].

The authors report the strategy of invasive management of Rh alloimmunisation in pregnancy. From the 34 pregnancies 6 were monitored by amniocenteses, 11 by fetal blood sampling, and 4 with combination of the two above mentioned diagnostic procedures. In 13 cases the fetuses were treated with intrauterine intravascular blood transfusions.

Screening for in vitro haemolysing antibodies.

The purpose of this study was to establish the frequency of the occurrence of in vitro haemolytic antibodies in donors, pregnant women and patients. The relatively high incidence of the Lewis blood group antibodies both in the group of pregnant women and patients is underlined.

Toxic shock syndrome following septoplasty and partial turbinectomy.

A rare case of toxic shock syndrome developing after an elective septoplasty and partial turbinectomy is reported. The sterile vaseline gauze packing acting as a "nasal tampon" is postulated as the mechanism of insult. The symptomatology, investigation and management of this case are discussed.
