Biological activity of metal complexes. I. Interaction of pt(II), pd(II) and rh(I) complexes with E. coli strains and with mice LS fibroblasts in vitro.

The effects of a number of Pt(II, Pd(II) and Rh(I) complexes against cultures of Escherichia coli (strains B, H10178, uvra-, recA-) and cultures of mice LS Fibroblasts were tested. Most of the compounds showed higher cytotoxic activity than the cis-Pt(NH3)2Cl2, the compound at present on clinical trial as antittumour drug. A new model of active compound is proposed.

Bone marrow transplantation for severe aplastic anemia. A report of 9 cases.

9 patients with severe aplastic anemia (SAA) were treated with bone marrow transplantation (BMT). 5 were conditioned with cyclophosphamide and received and HLA-identical graft (4 patients) or a mismatched graft (1 patient): 1 rejected the graft on day 30 and died on day 34 during conditioning for a second transplant; 1 died on day 15 with acute and severe graft versus host disease (GvHD) in the absence of haemopoietic engraftment; 3 are alive and complete chimeras at 1,069, 490 and 332 days after transplantation. GvHD developed in 4 patients and was treated successfully in 3 with high dose methylprednisolone and/or antilymphocytic globulin (ALG). 4 patients were conditioned with ALG and received bone marrow from a haploidentical sibling or parent: 1 patient was refractory; 3 patients showed evidence of hematologic reconstitution, but 2 of these required a second course of ALG. 3 patients in this group are alive between 60 and 490 days; 1 patient died on day 121 of HBSAg-negative acute hepatitis.

A to O bone marrow transplantation in severe aplastic anaemia: dynamics of blood group conversion and demonstration of early dyserythropoiesis in the engrafted marrow.

A to O bone marrow transplantation was performed in a 25-year-old male affected with severe aplastic anaemia, the donor being an HLA compatible brother. Three plasma exchanges had to be performed with an Aminco separator to remove the original and recurring anti-A isohaemagglutinins. The dynamics of O to A blood group conversion were followed by means of differential agglutination. An early wave of marked dyserythropoiesis was observed in the engrafted marrow. Mild to moderate GvHD was treated successfully with MTX, bolus high dosage 6-methylprednisolone and, at relapse, with intravenous ALG.

Peptichemio: A new oncolytic drug in combination with vincristine and prednisolone in the treatment of non-Hodgkin lymphomas.

Peptichemio, a new oncolytic drug with alkylating and antimetabolic properties was employed in combination with vincristine and 6-methylprednisolone (PVP) for the treatment of diffuse non-Hodgkin's lymphomas (NHL), stages III and IV. 52 of 66 patients who entered the PVP protocol were considered evaluable: the overall remission rate in diffuse lymphocytic poorly differentiated lymphomas (DLPD) was 56.6 and 55% in diffuse histiocytic lymphomas (DHL). Median duration of complete remission was 16 months in DLPD and 13 months in DHL. Dramatic results were obtained in "oncologic emergencies," such as mediastinal involvement and spinal cord compression. Bone marrow depression from PVP was moderate and never caused discontinuation of therapy. According to these results the PVP protocol would appear susceptible of offering a major contribution to the chemotherapy of diffuse NHL.

The treatment of autoimmune blood diseases with antilymphocyte globulin.

Twelve patients with immunologically mediated diseases have been treated with ALG, alone or in combination. Tolerance was good. Indvidual case reports are discussed. Emphasis is placed on the duration of ALG-induced remissions, as well as on its favourable effect in humorally mediated autoimmune diseases. The absence of notable side effects, especially with the more recent and refined preparations, is stressed.

Immunofluorescent diagnosis of acute lymphoblastic leukaemia.

When leukaemic lymphoblasts from acute lymphatic leukaemia were reacted with animal anti-human lymphocyte globulin (AHLG), and subsequently with the appropriate, fluorescein-isothiocyanate-conjugated antibodies, a brilliant membrane fluorescence was observed, which persisted up to 5 log titres, breaking from rings into spots at higher dilutions. The best results were obtained with fresh suspensions and incident illumination. Cross-reactions with mature and immature myeloid cells with the unabsorbed antisera could be abolished by repeated preabsorbtion of AHLG with packed leukocyte preparations from chronic and acute myeloid leukaemias. Thus, it appears that this approach is susceptible of improving the identification of leukaemic lymphoblasts, and may be extended, by means of appropriate antisera, to the acute leukaemias in general.

Anabolic agents in kidney disease: the effect of formebolone on protein synthesis in patients with renal insufficiency or nephrosis.

The anabolic activity of formebolone was studied in 7 patients with nephrosis or renal insufficiency by measuring the amount of 14C-leucine incorporated into plasma proteins as an index of protein synthesis. The data demonstrate that the incorporation of label into the plasma albumin fraction was significantly increased after formebolone administration.

Modifications of macrophage chemotaxis in rats bearing the transplantable tumour reticulosarcoma 'IRE'.

Macrophage chemotactic activity was studied as a marker of the anti-inflammatory effect accompanying tumour growth. An inhibiting effect of the tumour on the macrophage mobility was observed by comparing the macrophages collected from normal rats and those from animals bearing the IRE reticulosarcoma. To explain these results, it is postulated that a MIF, or a similar inhibiting factor is released by the tumour. Both the the nature and function of such a factor(s) remain to be clarified.

[Epilepsy and pregnancy: preliminary studies].

The study concerns 17 clinical cases of epilepsy during the progress of 32 pregnancies. It is reported the frequency variations of epileptic fits, the eventual pharmacological adjustments and also some parameters of influence on the newborn. The result are briefly argued.

[Candida albicans infection: in vitro immunity aspects].

The authors have investigated the chemotactic ability of C. albicans toward macrophages and polymorphonuclears. Experiments, carried out by modified Boyden chamber, lead to isolate a chemotactic agent, considered either a moderate cytotaxin, or an excellent cytotaxigen.
