    Notes: Summary The precise distribution of substance P (SP) binding sites in the human brainstem was investigated in normal cases (3 fetuses and 24 newborns) and in 9 cases of Sudden Infant Death Syndrome (SIDS) by in vitro quantitative autoradiography. We discussed the widely but uneven distribution of SP binding sites as regards to the role of SP in brainstem cardio-respiratory ontogenic control and its possible involvement in SIDS.

    Notes: Abstract  Agricultural management practices affect earthworm populations. A field experiment was conducted to determine the effect of two rotations and two tillage systems on earthworm population density and biomass in a claypan soil. The rotations were soybean/corn and wheat/corn, and the tillage systems were conventional tillage (chisel plowed and disked) and no-tillage. Earthworm and soil samples were collected in fall 1995, spring 1996, and fall 1996. Aporrectodea trapezoides and Diplocardia singularis were the species identified at the site. A. trapezoides accounted for 92–96% of the total earthworm population density and D. singularis accounted for only 4–8%. In a no-till system, soybean/corn rotation resulted in significantly greater population density of A. trapezoides compared with the wheat/corn rotation. Crop residue quality (low C:N ratio) and quantity were important factors in increasing A. trapezoides population density and biomass. Conventional tillage markedly decreased population density and biomass of both earthworm species. Our results suggest that rotation and tillage significantly affect earthworm population density and biomass.

    A phase I study of gemcitabine, 5-fluorouracil and leucovorin in patients with advanced, recurrent, and/or metastatic solid tumors (1998)

    Notes: Abstract Introduction: This was a dose escalation phase I trial designed to establish the MTD (maximum tolerated dose) and toxicity profile of the combination of gemcitabine, leucovorin and 5-fluorouracil (5-FU). Methods: Standard eligibility criteria were required for patients with advanced malignancy to enrol. Gemcitabine was escalated from an initial dose of 800 mg/m2. Gemcitabine was administered prior to leucovorin (25 mg/m2) followed by bolus 5-FU (600 mg/m2) every week for 3 weeks followed by 1 week of rest. Results: Of 21 patients enrolled, 20 were eligible for MTD determination. Patients received a median of three 4-week cycles of chemotherapy (range: 1 to 8 cycles). Toxicity was predominantly hematologic or gastroenterologic. Four dose levels were studied. At a gemcitabine dose of 1,500 mg/m2 systemic symptoms of fatigue accompanied hematologic toxicity and patients refused further therapy. At 1,250 mg/m2, full dose intensity was not delivered during the first cycle in 7 of 8 patients treated. Therefore, 1,000 mg/m2 was established as the recommended phase II dose for gemcitabine in this study. Antitumor activity was seen at all dose levels. Conclusions: The combination of gemcitabine, leucovorin and 5-FU was tolerable at full doses of all 3 drugs with an expected toxicity profile. Recommended phase II dose for gemcitabine was 1,000 mg/m2. Initial evidence of clinical activity was seen in a variety of tumor types.
