Phase I clinical and pharmacologic study of intraperitoneal cisplatin and fluorouracil in patients with advanced intraabdominal cancer.

Fluorouracil (5-FU) and cisplatin display marked therapeutic synergy in preclinical models and are effective in the treatment of a number of solid tumors when combined and administered intravenously (IV). Each drug has also been administered intraperitoneally (IP) and displays a favorable pharmacologic profile and acceptable clinical toxicity. We therefore undertook a phase I study to determine the feasibility and toxicity of combination IP chemotherapy with these agents.

Plasma pharmacokinetics of high-dose oral melphalan in patients treated with trialkylator chemotherapy and autologous bone marrow reinfusion.

The pharmacokinetics of melphalan following high-dose p.o. administration were determined in 17 patients with various malignancies for the purpose of assessing interpatient and intrapatient pharmacokinetic variability.

High-dose, multiple-alkylator chemotherapy with autologous bone marrow reinfusion in patients with advanced non-small cell lung cancer.

Fifteen patients with Stage IV lung cancer both untreated and previously treated were enrolled into a high-dose chemotherapy program with multiple alkylating agents and autologous bone marrow reinfusion. Eight patients received cyclophosphamide at 7.5 gm/m2 over 3 days with thiotepa escalated from levels of 1.

Photosynthesis and Photorespiration in Typha latifolia.

Photosynthetic rates of Typha latifolia, the broad-leaved cattail, are the equivalent of rates reported in tropical grasses and other plants which assimilate carbon by the phosphopyruvate carboxylase reaction, but photosynthesis in T. latifolia proceeds by a typical Calvin cycle. Glycolate oxidase, the photorespiratory enzyme, is present in high concentration in this species, but only minor quantities of the assimilated carbon pass through the photorespiratory pathway.
