    Diet, bacteria and colonic cancer (1999)
    Bingley : Emerald
    Nutrition & food science 99 (1999), S. 187-193 
    Details
    ISSN: 0034-6659

    Notizen: The links between diet, bacteria and colonic cancer are examined in this article. Studies suggest that high intakes of fat and protein are associated with elevated risk of colonic cancer whereas cereals, fruits and vegetables seem to be protective. A further aspect considered in relation to this type of cancer is metabolism by gut bacteria. Probiotics, prebiotics and synbiotics are presented as ways of stimulating the activities, certain gut flora and the use of "functional foods" is also discussed.

    Differential solubility of subcomponents of rat glomerular basement membrane (1984)
    Springer
    Bioscience reports 4 (1984), S. 319-326 
    Details
    ISSN: 1573-4935

    Thema: Biologie , Chemie und Pharmazie
    Notizen: Abstract Marked differences were found in the electrophoretic profiles and amino-acid compositions of components prepared from rat glomerular basement membrane (GBM) by a number of different solubilization procedures. Treatment with reducing agent resulted in a simplified electrophoretic pattern which was characterized by the presence of a major collagenous component with a mol.wt, of 150 000. In contrast, detergent solubilized mainly lower-mol.-wt, material which had a more polar amino-acid composition. When both reagents were used together the majority of the basement-membrane material was soJubilized within 2 h and components with mol.wts, of 170 000 and 135 000 were predominant i n the pro-α region of the gel. Treatment for a further 16 h was required to solubilize higher-mol.-wt, material and to achieve maximum solubility of components in the pro-α region with mol.wts, of 185 000 and 150 000. These methods provide a means of separating subcomponents of rat GBM while avoiding the problems of degradation inherent in enzymatic procedures.

    Phase II evaluation of echinomycin (NSC-526417) in patients with central nervous system malignancies (1993)
    Springer
    Journal of neuro-oncology 15 (1993), S. 181-184 
    Details
    ISSN: 1573-7373
    Schlagwort(e): echinomycin ; central nervous system malignancies
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary The objective of this trial was to determine the efficacy of echinomycin (1.2mg/m2) administered on a weekly times four schedule in the treatment of patients with recurrent or progressive central nervous malignancies despite adequate radiotherapy. Thirty-five patients were registered on study. The majority of patients (20) had glioblastoma multiforme. Ten had anaplastic astrocytoma. Eight patients had received prior nitrosoureas. SWOG performance status was 1 in 11 patients and 2 in 22. The median age was 51 years (25–75 years). One patient had a partial remission (3%:95% confidence interval: 1%–16%). Twenty two patients had progressive disease. The median survival was 5.9 months. Toxicity was primarily gastrointestinal with nausea and vomiting in 13 patients and nausea only in 11 patients. Hepatotoxicity occurred in 10 patients. Echinomycin given at this dose and schedule is not effective in treating patients with recurrent or progressive glioblastoma multiforme or anaplastic astrocytomas.

    New agents in the treatment of primary brain tumors (1994)
    Springer
    Journal of neuro-oncology 20 (1994), S. 141-153

    ISSN: 1573-7373

    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary A review of single agent trials of cytotoxic agents in adults with high grade gliomas is presented. The rationale for testing these agents in patients with brain tumors was variable and is discussed. The criteria to evaluate responses were also variable ranging from subjective evaluation of clinical improvement with a stable radiographic assessment to the same objective response criteria utilized for solid tumors. Trials of agents specifically designed for brain tumors such as AZQ and spiromustine have been disappointing. There are encouraging results being seen in early trials of newer agents which await confirmation in larger trials but which hold promise for improving the disappointing results seen so far with chemotherapy in primary brain tumors.

    Phase II study of aziridinylbenzoquinone (AZQ) in patients with central nervous system malignancies: a Southwest Oncology Group study (1985)

    Thema: Medizin
    Notizen: Summary AZQ, an alkylating agent with lipophilic characteristics allowing CNS penetration was studied in patients with primary CNS malignancies refractory to surgical and radiotherapeutic modalities. Responses were evaluated by three criteria: neurologic examination, performance status and CT scan of the brain. Improvement in all three parameters with stable or decreasing doses of decadron was required for a partial response. Thirty-six poor risk (prior chematherapy) patients with Grades III and IV astrocytomas were treated with 30 mg/m2. Three patients had a partial response (14, 17, 60 weeks duration). Two patients had mixed responses (worsening of one disease parameter with improvement in another), four had stable disease and one patient had improvement in neurologic parameters with a stable CT scan. Twenty-six patients had increasing disease. Fifteen good risk patients (no prior chemotherapy) with recurrent grades III and IV astrocytomas were treated at a dose of 40 mg/m2 intravenously every three weeks. There were no objective responses in this group of patients. Three patients with nonastrocytomas were treated and no responses observed. The drug was well tolerated. Myelosuppression in the form of leukopenia and thrombocytopenia was the major toxicity. Myelosuppression required dose reductions in eight patients and discontinuation of therapy due to repeated treatment delays in two patients. AZQ at doses of 30 and 40 mg/m2 given on an intermittent bolus schedule is inactive in patients with Grades III and IV recurrent astrocytoma.

    Thema: Chemie und Pharmazie , Medizin
    Notizen: Abstract Menogaril, a semisynthetic anthracycline antibiotic, was administered to patients with metastatic adenocarcinoma of the prostate. Forty-five patients with measurable disease and 45 patients with evaluable disease received 150–200 mg/m2 over 1 hour every 28 days. There were three partial responses (PR) among 87 patients evaluable for response. Myelosuppression was dose limiting. There were two deaths related to leukepenia. Other toxicities included phlebitis, alopecia, nausea and vomiting. One patient developed acute nonlymphocytic leukemia. Menogaril at these doses and schedule is toxic and has no signficant antitumor activity in metastatic adenocarcinoma of the prostate.

    Notizen: Abstract Didemnin B 6.3 mg/m2 was administered intravenously to 48 patients with recurrent or progressive central nervous system tumors. One patient of 39 (2.9%, 95% confidence limits 0.1 to 13.5) eligible patients had a confirmed partial response utilizing standard solid tumor criteria which lasted 14 months. Toxicity was significant. Nausea and vomiting and lethargy were the most frequent toxicities, but multiple severe toxicities were seen. Further investigation of Didemnin B at this dose is not warranted in patients with central nervous system malignancies.

    Notizen: Summary Patient with advanced adenocarcinoma of the pancreas and no prior chemotherapy were treated on a Phase II trial of mitoxantrone. Doses were adjusted for hepatic dysfunction as defined by bilirubin. Twenty-four patients with a bilirubin ⩽ 1.5 mg% received mitoxantrone 12 mg/m2 i.v. repeated every three weeks. Myelosuppression in the form of leukopenia was the major toxicity. There were no responses in twenty-four evaluable patients.

    Notizen: Summary The Southwest Oncology Group studied the response rate and toxicity of didemnin B (3.47 mg/m2 i.v. q 28 days) in patients with advanced renal cell carcinoma. There were no responses in 22 response evaluable patients. Toxicity was significant with 10 patients having grade 3 or 4 toxicity. Toxicity seen included nausea and vomiting, exacerbation of coronary artery disease, hyperglycemia, anorexia, diarrhea and hepatitis. Didemnin B was toxic but inactive in patients with renal cell treated at this dose.
