Cross-reactive antibodies against human cultured B cells and bovine erythrocytes in human renal transplantation sera.

Sera of 58 recipients of renal allografts were studied for the presence of antibodies against cell cultures of human B lymphoid cell lines (B-LCL) and bovine erythrocytes (BRBC). Cytotoxic anti-B-LCL antibodies were found in 13% of the sera from recipients with the grafts and in 67% of the sera obtained after removal of the rejected grafts. Most of these sera also contained BRBC lysins of high titers. Absorption studies showed that the anti-B-LCL antibodies are directed against antigens shared by BRBC and that they can be absorbed with corresponding graft tissues. The specificity of BRBC lysins found in some of the transplantation sera was shown to be similar to that of Hanutziu-Deicher antibodies.

Screening of anti-B cell antibodies in the sera of renal transplant recipients by using Daudi cell line.

In order to examine the presence of antibodies against B cells, 83 sera obtained from 55 renal transplant recipients were screened by microcytotoxicity test using Daudi cell line. Out of 83 samples, 12 were pretransplant sera, 62 were post-transplant sera and 9 were from the patients whose grafts has been removed due to rejection. For the purpose of improving the reliability of the tests, 5 different rabbit complements were selected and cytotoxicity tests with them were carried out simultaneously. Pretransplant sera without blood transfusion did not show any cytotoxicity against Daudi cells. Although 42% of post-transplant sera showed cytotoxicity against Daudi cells, cytotoxic activity of the sera showed no relation with the occurrence of rejection episodes. Three serum samples out of 5 patients whose grafts had been removed due to rejection showed strong cytotoxicity against Daudi cells and the sera of 2 other patients did not. There was no relation between the cytotoxicity against Daudi cells and antibodies against Epstein-Barr virus capsid antigen in the post-transplant sera.

Chorio-meningo-encephalitis due to Listeria monocytogenes after renal transplantation.

A 35-year-old man, who underwent renal transplantation, died of meningo-encephalitis with symptoms of meningitis for only 8 days. The autopsy revealed marked chorio-meningo-encephalitis caused by Listeria monocytogenes. This report on listeriosis in renal transplant patients is the second in our country, where adult cases of listeriosis are rare. Recent knowledge about listeriosis in renal transplants is reviewed and discussed.

Heterophile antibodies in the sera from renal transplant recipients.

Microcytotoxicity tests with the sera from renal transplant recipients against cultured B-cell lines were performed by using guinea pig complement. Out of 106 sera, 18 sera showed strong cytotoxicity against cultured cell lines. The same results were obtained by using normal human serum as a complement source. These sera did not show any cytotoxicity against normal peripheral T- and B-lymphocytes. On the other hand, the sera containing the cytotoxicity against cultured B-cell lines were found to have high-titered heterophile antibodies against bovine red blood cells (BRBC) when hemolysis in agar gel with guinea pig complement was used. The sera without cytotoxicity did not have high-titered heterophile antibodies. The sera with cytotoxicity against cultured B-cell lines reacted in the same way against both human tonsilar lymphocytes cultured with the medium containing fetal calf serum and human serum. Therefore, the antigenicity of cultured cells was not affected by the fetal calf serum in the culture medium. After absorption with BRBC, the sera lost their cytotoxicity against cultured cells. Hemolysins in the sera were almost completely removed after absorption of the sera with cultured cells. From these results, it seemed apparent that the sera from renal transplant recipients contained heterophile antibodies which reacted with the cells of some cultured B-cell lines and tonsilar lymphocytes.

Effects of the combination of tumor-specific and nonspecific immunization on tumor suppression.

The crushed whole Aoyama B cells attached to oil droplets were found to be most suitable for the adjuvant effect of Mycobacterium tuberculosis against tumor growth when judged by the criterion of effectiveness and a clinical application with minimal side effects. The immunogenicity of tumor cells was well stabilized and maintained with a suitable concentration of formalin; this was less than 1% and the optimum concentration was 0.05% or 0.1%. When the tumor cells treated with the optimum concentration of formalin were combined with suitable adjuvant, immunoprotection against the tumor progress was accelerated.

Immunologic and chemical studies on mucopolysaccharide derived from murine lymphosarcoma.

Mucopolysaccharide was prepared from media in which the Gardner's lymphosarcoma cells were cultured. Multiple intraperitoneal injections of the preparation into syngeneic mice resulted in enhancement of the tumors which were inoculated prior to the injections. Sera of these hosts contained antibodies reacting with antigens of the outer layer of the tumor cells. Chemical analyses of the preparation showed that the mucopolysaccharide is composed of hexosamine, uronic, acid, hexose, and proteins. The mucopolysaccharide was shown to possess unique migration rate on electrophoresis and thin layer chromatography.

Properties of hepatic tissue extracts: 2. An approach to the artificial liver.

In the previous paper [3], the lethal effect of normal rabbit liver extract intravenously infused into rabbits was described. By comparing to the course of destruction of the liver tissue in fulminant hepatitis, the toxicity of the liver extract was recently studied. Attempts were also made to adsorbing the liver extract by activated clay and detoxifying the liver extract with a formaldehyde solution, and the results suggested that the findings would be applicable as an approach to the artificial liver.
