Renal deposition of soluble immune complexes in hamsters bearing an SV40-induced tumour.

Histologic and immunofluorescence studies of the kidneys of hamster bearing a tumour induced by injection of SV40-transformed cells show a proliferative glomerulonephritis associated with the presence of immune complex deposits along the glomerular basement membrane and in the mesangium. The intensity of the deposit is dependent of the size of the tumour. The presence of SV40-induced antigens was identified in the complexes by a heterologous immune serum. Immunoglobulins eluted from kidneys were shown to react with SV40 antigens by immunoprecipitation with TSV5CL2 cell extracts and by fluorescence on CV1 infected cells.

Cyclophosphamide induction of splenic suppressor cells in hamsters.

Injection of hamsters with a single sublethal dose of cyclophosphamide induced splenic atrophy followed by considerable hypertrophy. During the splenomegaly phase, the in vitro reactivity of spleen cells to concanavalin A (ConA) or protein A (ProtA) was decreased. The spleens of 6-8-month old animals contained cells able to suppress the in vitro reactivity of normal lymphocytes to ConA or ProtA. These cells were absent in 2-month old animals, and some suppressor activity could be shown in 3-month old hamsters. Suppressor activity was abolished by removal of adherent cells and by silica treatment, but antisera against thymocytes or IgG were ineffective.

[Action of cytotoxic drugs on normal hepatic tissue in the baboon. Immediate and late lesions].

The perfusion of cytotoxic drugs in the treatment of inoperable tumours of liver is used even in children. The experiment described here was planned to study the effect of three cytotoxic drugs (5. Fluorouracil, Méthotrexate and S.P.I.) on the liver of healthy baboons. The drugs were introduced by perfusion through the hepatic artery. Liver biopsies were performed at the end of the treatment and 15 and 60 days later. In order to avoid acute toxic effects, low doses of the drugs must be given during the first five days. The therapeutic dose can then be increased and maintained for variable periods. Of the three products tested, the toxicity increases in the following order: S.P.I., 5 F U. and Methotrexate.

[Cellular and humoral response to tumor antigens in the hamster].

Studies on the histological of the lympoid organs and the evolution of the immune response were done during the growth of a tumour induced by SV40 transformed cells. The immune response was characterized by a high level of circulating antibodies and presence in the thymus and spleen of lymphoid cells containing IgG with antibody function.
