Intramitochondrial location and some characteristics of chicken liver aspartate aminotransferase.

Chicken liver mitochondrial aspartate aminotransferase was found to be located in the intermembrane space and bound to the inner mitochondrial membrane. Purification of two mitochondrial fractions containing aspartate aminotransferase activity was performed. Both fractions showed similar chromatographic behaviour and identical isoelectric point and molecular weight values. There were no significant differences in the general kinetic mechanism, Km values, substrates inhibition and effect of various anions on the activity of mitochondrial aspartate aminotransferase purified from both fractions.

A kinetic method for quantification of aspartate aminotransferase isoenzymes.

A spectrophotometric assay is proposed to determine the levels of aspartate aminotransferase (AAT) isoenzymes from chicken liver by a steady-state kinetic method which depends on the differential inhibition of these isoenzyme forms by high concentrations of substrate 2-oxoglutarate at pH 6.2. The use of a standard curve permits the determination of the percentage of chicken liver c-AAT and m-AAT isoenzymes. This method yields results in good correlation with those achieved by different extent adipate inhibition and by differential centrifugation.

The transition stages between the main aphasic syndromes.

One of the basic features of most aphasic patients is their clinical dynamics, i.e. the continuous change in language function. The functional Dynamic Approach on which our rehabilitation program is based, can be expressed as a model of dynamic movement in which a patient's progress from one syndrome to another can be documented quantitatively. In this study we have concentrated on the initial emergence of patients out of the major syndrome categories. Our language test "I.L.A.T." provides for the evaluation of changes in the four language functions. Relative changes are charted by establishing a theoretical maximum performance to be expected in an aphasic population and noting improvements from the initial condition towards that point. Quantification of the proposed transitional stages are currently being developed to document our clinical insights.

Twelve years of experience with cytotoxic therapy in malignant tumors of the neck and head.

Since 1968 we have treated with antiblastic drugs 164 malignant tumors recurrent or incurable by surgery or radiotherapy in 151 cases. Different therapeutic methods were employed. Today we have the possibility of selecting alternative options with incipient or relatively delimited carcinomas, principally the substitution of radical surgery by initial associated physical and chemical treatment, so that if there is a cure the consequences of radical surgery can be avoided. We emphasize the curve of two primary cancers of the uvula with 300 mg bleomycin exclusively and the results observed in oropharyngeal and laryngeal carcinomas by using three intermittent Schabel cycles and 4,000 rad Telecobalt, avoiding a radical surgery.

Preliminary results of chemoradiotherapy followed (or not ) by active immunotherapy of stage III and IV lymphosarcoma and reticulosarcoma: correlation of the results with WHO categorization.

One hundred and one patients with advanced (stage III and IV) LS and RS at the first presentation of the disease or on relapse were treated with a regimen combining initial chemotherapy, complementary radiotherapy on "icebergs," supplementary chemotherapy, and finally, active immunotherapy. The overall complete remission rate was about 79% for LS and 73% for RS. About 50% of the patients were still in remission for both diseases after 2 years; 60% with LS were still alive after 2 years and 44% with Rs. This study shows the useful prognostic value of the WHO classification for LS and RS: the prognosis of prolymphocytic (centrofollicular) LS is far better than that of the lymphoblastic type, which is itself better than that of the very poor prognostic immunoblastic type. The prognosis of RS is intermediate between that of the best prognostic type and that of the poorest prognostic type of LS.

Preliminary results of chemo-radiotherapy followed or not by active immunotherapy of stage III and IV lymphosarcoma and reticulosarcoma. Correlation of the results with WHO categorisation.

We treated 101 patients with advanced (stage III and IV) lymphosarcoma and reticulosarcoma at first presentation of the disease or in relapse according to a protocol combining initial chemotherapy, complementary radiotherapy on icebergs, supplementary chemotherapy, and, finally, active immunotherapy. The overall complete remission rate was about 79% for lymphosarcoma and 73% for reticulosarcoma. About 50% of the patients were still in remission in each of the two diseases at 2 years; 60% of lymphosarcoma and 44% of reticulosarcoma patients achieved 2-year survival. This study shows the prognostic value of the WHO classification for lymphosarcoma and reticulosarcoma: the prognosis of prolymphocytic (centrofollicular) lymphosarcoma is far better than that of the lymphoblastic type, which is in turn better than that of the very poor prognosis of the immunoblastic type. The prognosis of reticulosarcoma is intermediate between that of the best-prognosis and that of the poorest-prognosis type of lymphosarcoma.
