Semecarpus anacardium (SA) popularly known as marking nut has been used in folklore for the treatment of a wide range of diseases. Extracts (hydro-alcoholic and oil) of SA were evaluated for their anticancer activity against Ehrlich ascites carcinoma (EAC) in nude mice. Extracts and standard drug (cyclophosphamide) at a dose of 20 mg/kg body weight were administered orally and continued for 10 ...

BACKGROUND The objective of the present study was to evaluate the efficacy of a simple, versatile and cost-effective immunosuppression protocol, using cyclosporine, ketoconazole and cyclophosphamide drug regimen to develop human tumor xenograft in mice. MATERIALS AND METHODS Cyclosporine, ketoconazole and cyclophosphamide drug regimen was administered to C57BL/6 mice to induce immunosuppressi...

Weekly i.p. injections of killed Corynebacterium parvum and of cyclophosphamide (given on different days) strongly inhibited growth of a transplantable murine mammary adenocarcinoma. A significant portion (40 to 80%) of animals could be made tumor free by means of combined therapy. No tumor-free survivors were obtained with C. parvum alone, and tumor-free mice were obtained with cyclophosphamid...

The immunosuppressant cyclophosphamide easily induces specific immunological tolerance in CBA mice, but is unable to produce an immunological defect in adult thymectomized animals. In contrast, lethal (and sublethal) irradiation does not induce tolerance but readily brings out the deficit of thymectomy. Furthermore, bone marrow cells which protect lethally irradiated animals do not prevent drug...

Postimplantation rat embryos (Day 10) were exposed in vitro to teratogenic concentrations of 4-hydroperoxycyclophosphamide, an activated form of cyclophosphamide, and phosphoramide mustard, the major teratogenic metabolite of cyclophosphamide. Following a 5-h exposure to these agents, drug-induced DNA damage was assessed by alkaline elution. Both drugs induced detectable DNA cross-linking at te...

A 5 1/2-yr-old child developed severe anemia with erythroid hypoplasia and 50% ringed sideroblasts in his bone marrow. A serum inhibitor of erythropoiesis was demonstrated, utilizing syngeneic and autologous bone marrow in a plasma-clot culture system. The IgG fraction of the patient's serum effected similar suppression of erythroid colony formation. Prednisone therapy was ineffective, but foll...

A randomised study comparing cisplatin 120 mg intravenously with cyclophosphamide 2 g intravenously, each drug being given every month for six months followed by a low dose regimen for a further six months in responding patients, was carried out in 86 patients with advanced epithelial ovarian carcinoma (FIGO stages III and IV). Patients given cisplatin were found to have a longer median surviva...

occur with some anticancer agents such as cyclophosphamide (Shah et al., 1975), 5-FU and nitrogen mustard (Moore and Meiselbaugh, 1975), and also with exposure to x-rays (Sutton, 1952; Inalshingh, 1972). Priestman and James (1975) reported 3 cases in which nail changes were possibly due to doxorubicin. They speculated that this drug has a selective hormone-suppressive action which might allow a...

Combination chemotherapy with cyclophosphamide, methotrexate and fluorouracil (CMF) was compared with cyclophosphamide, adriamycin and fluorouracil (CAF) as adjuvant to modified radical mastectomy in primary operable breast cancer with positive axillary lymph nodes. After 18 months of study, treatment failure occurred in 10% patients in each group. The new clinical manifestations occurred local...

Granulomatosis with polyangiitis and microscopic polyangiitis are anti-neutrophil cytoplasmic antibody-associated vasculitides (AAVs) that are prone to cycles of remission and relapse. The introduction of cytotoxic therapy has changed the prognosis for these diseases from typically fatal to manageable chronic illnesses with a relapsing course. Despite improvements in outcomes, recurrence of dis...
