Cyclosporin A initially as the only immunosuppressant in 34 recipients of cadaveric organs: 32 kidneys, 2 pancreases, and 2 livers.

34 patients treated with cyclosporin A received 36 cadaveric organ allografts (32 kidneys, 2 pancreases, and 2 livers), 26 kidneys are still supporting life, 3 after more than a year; the pancreases and livers are also functioning. 20 patients are not receiving steroids, and 15 of these have not had any additional immunosuppressive agents. In these patients infectious complications have not been severe, but a gastroduodenal lymphoma has developed in 1 patient. 6 patients were given 'Cytimum' (a cyclophosphamide derivative) and steroids in addition to cyclosporin A: 5 of these died of infections and 1 also had a lymphoma. 11 patients received additional steroids: 1 of these died from septicaemia and lymphoma. Nephrotoxicity can be avoided by perioperative hydration and forced diuresis. Cyclosporin A is effective on its own and is a very potent immunosuppressive drug. Additional immunosuppressive agents may lead to severe complications.

Diversity and complexity of uterine mRNA from rats of differing hormonal states.

The diversity and complexity of the uterine mRNA population has been compared at two different stages of uterine growth and development in the rat. Analysis by cDNA hybridization to homologous mRNA indicates that there are 8000 different sequences expressed in the immature rat uterus responding to just 4 h of oestradiol-17 beta-induced growth while the fully developed uterus expresses 36 000 sequences. As a check on our results, the complexity is re-analysed by hybridization of mercurated mRNA to total unique DNA. Analysis by this method indicates that the hormone-stimulated immature rat uterus contains 12 000 poly(A)-containing mRNA sequences while the fully differentiated adult tissue contains 53 000 diverse sequences.

Qualitative and quantitative changes in uterine mRNA populations in response to oestradiol treatment of rats.

The mRNA population of immature rat uteri, responding to different lengths of oestradiol-induced differentiation, have been compared by the technique of DNA hybridization with heterogeneous RNA. Over the first 4 h of hormone induction there are continuing qualitative and quantitative changes in the poly(A)-containing mRNA such that, by 4 h after oestradiol administration, the population bears little resemblance to that of the unstimulated animal. Between 2 h and 4 h after oestradiol administration, the most striking changes appear to be in sequences of intermediate abundance. The possible significance of these findings is discussed.

Diabetes mellitus with immune complex glomerulonephritis.

The present study describes 3 patients with the simultaneous occurrence of diabetic nephropathy and immune-complex mediated glomerulonephritis. Renal manifestation included proteinuria and hematuria which were preceded by or co-existent with an infectious process. Renal manifestation included proteinuria and hematuria which were preceded by or co-existent with an infectious process. Renal histology showed the characteristic change of diabetic nephropathy along with those of immune complex glomerulonephritis. Immunofluorescence studies showed a linear pattern with a superimposed granular pattern of IgG and C3 deposits. Renal function and urinary findings improved in the 2 patients who were followed up.

Characterization of uterine heterogeneous nuclear ribonucleic acid and the effect of oestradiol-17 beta on its synthesis.

An early response to the administration of oestradiol-17 beta to immature rats is a dramatic stimulation in the synthesis of uterine hnRNA (heterogenous nuclear RNA). High-molecular-weight fractions of the hnRNA were purified and subfractionated on poly(U)-Sepharose into fractions that differed in their poly(A) content and their size profile on polyacrylamide gels. Oestrogen treatment of the rats stimulated the synthesis of all three fractions of high-molecular-weight hnRNA, but the kinetics of synthesis, degree of stimulation and size distribution of the newly synthesize RNA differed in each fraction.
