With the aim of establishing bio-indices for the development of multistep hepatotumorigenesis, rats were fed water containing 0.01% diethylnitrosamine (DEN) ad libitum for 13 weeks. This treatment with DEN only made it possible to induce hepatic tumors in 100%. After the DEN administration, several clinical symptoms were observed including minor behavioral changes, brittleness of hair and a decrease in water and food intake. The concentration of total serum protein and albumin in all treated groups was significantly lower than in non-treated controls (p<0.05). Increase of specific enzyme (AST, ALT and GGT) activity (p<0.05), variable tumor size and hepatomegaly of the liver was observed in all rats treated with DEN for 10 weeks. Both hepatocellular carcinoma and cholangiocarcinoma were found in the same livers at the same time, and were prominently developed after 12 weeks. In case of carcinoma, some of the livers showed more or less advanced states over the 12-15 weeks period. In the present study, hepatocellular carcinoma was developed by treating DEN in only the drinking water, without any other carcinogens or without partial hepatectomy. These results indicate that DEN is a new carcinogen that acts directly on it the liver, moreover, it might be very useful for investigating hepatotumorigenesis.

OBJECTS: There was a trend to perform fusion and instrumentation in spinal stenosis surgery, because of extensive decompression and instability. However, the introduction of microscope in spine operation can minimize the range of excision of anatomical structure and reduced the decompressin level in the multiple lesions and the incidence of spinal fusion. The purpose of this study were to assess the outcome of this procedure in 3 years follow up and to identify the clinical features of the patients and technical aspects of the operation that were associated with a poor outcome. MATERIALS AND METHODS: Twenty-one patients were identified as having had a microscopic decompression without arthrodesis, for degenerative lumbar spinal stenosis over 60 years or their who had osteoporosis with Saville's index 2 or higher. The follow up period was more than 3 years. The clinical results was evaluated by Kim's criteria. RESULTS: Eleven cases were above good results in two levels involved 14 cases, 2 cases above good results in three levels involved 5 cases and 1 case above good results in four levels involved 2 cases. In the cases of affected duration, 7 cases are less than 1 year or more than 5 years each 6 cases and 2 cases were above good results by the criteria. We concluded that the long-term outcome of decompressive surgery in the elderly is good; it does not differ from that reported for younger patients . CONCLUSIONS: Selective microscopic decompression is one of the effective method for the elderly patients or patients with osteoporosis in addition to multiple stenotic lesions.
