From September, 1984 to July, 1986 seventy previously untreated adult patients with advanced non-Hodgkin's lymphoma of intermediate or high grade histology were enrolled in an open phase III multicenter, comparative chemotherapeutic trial. The objectives were to compare, by means of response rate, duration of response and survival time, the efficacy and safety of substituting mitoxantrone for doxorubicin in the combination chemotherapy regimen m-BACOD (methotrexate, bleomycin, doxorubicin, cyclophosphamide, vincristine and dexamethasone). Thirty-five patients were randomly assigned to receive m-B-NOVANTRONE TM (mitoxantrone)-COD (m-BNCOD) and 35 m-B-ADRIAMYCIN TM (doxorubicin)-COD. The complete response rate was 57% for both treatment groups, and no significant disease-free survival and survival differences were found between the two groups of patients. Patients treated with m-BACOD experienced severe alopecia more frequently (p less than 0.001) and, after 10 cycles, six adverse cardiac event of WHO grade greater than 1, as opposed to none among those who received m-BNCOD. The mitoxantrone-containing regimen (m-BNCOD) has equivalent efficacy and reduced toxicity compared to the standard doxorubicin-containing regimen (m-BACOD) in patients with poor prognosis NHL.

Effectiveness of surgically induced acute hepatic failure in pig and most suitable time to apply artificial support in hepatic coma are evaluated in this work. Five male pigs weighing about 30-35 kg are employed. Latero-lateral porto-caval shunt was performed; the vascular disconnection of liver was obtained by ligature of blood vessels. Ligature was also placed on main biliary way after cholecistectomy. Blood samples were obtained (at 0, 1, 2, 6, 12, 18, 24 hours) to essay serum bilirubin, alkaline phosphatase and GOT-GPT levels as index of cholestasis and necrosis. Porto-caval encephalopathy was evaluated by means of serum ammonium levels, aminoacid pattern and E.E.G. Serum aminoacid pattern was carefully determined; its changes were found similar in man during coma. All pigs died 24-36 hours after surgery with liver ischemic and necrosis. Clinical and laboratory data obtained in experimental conditions were found similar to picture of acute hepatic failure in man, confirming validity of our model.
