The effect of different formalin concentrations on the nociceptive response in the formalin test was examined in mice. Subcutaneous formalin injection induces 2 distinct periods of high licking activity: an early phase lasting the first 5 min, and a late phase lasting 20-30 min after the injection. Formalin concentrations of 0.02-0.2% induced only the early(More)
The aim of this study was to test the prognostic contribution of estrogen (ER) and progesterone (PgR) receptor status to an index consisting of the number of positive lymph nodes, the mean nuclear area of the breast cancer cells (MNA), and tumour diameter. This index is compared with a Danish index, which includes the same factors but uses histological(More)
We have developed a standardized procedure for the isolation of monocytes from peripheral blood by negative selection using magnetic polymer particles coated with monoclonal antibodies against T and B lymphocytes. The average purity of the monocyte suspension was 85%, and monocyte recovery was 72% from Ficoll-Hypaque gradient separated mononuclear cells and(More)
We tested the hypothesis that hyperbaric oxygen (HBO) alone and with chemotherapy (5-FU) attenuates tumor growth of DMBA-induced tumors in rats. Six series were performed: (1) Controls (air and vehicle 0.9% NaCl i.p.), (2) 5-FU (0.2 mg/kg i.p.), (3) HBO (2 bar for 90 min and vehicle), (4) HBO and 5-FU, (5) HBO (11 days) and air (next 12 days), (6) HBO (23(More)
A case of a large spindle-cell lipoma in an intramuscular (subfascial) localization is reported. The tumour occurred in a 58-year-old male patient and was localized subfascially in his left deltoid muscle. The tumour measured 20 X 8 X 8 cm; its weight was 780 grams. After initial biopsy, the tumour was extirpated. Microscopically, the tumour tissue(More)
The present study consists of 1,238 women with unilateral breast cancer treated with modified radical mastectomy living in the geographic area of Haukeland Hospital. Their weight and height had been measured years before presentation of the disease. Age-adjusted Quetelet's index (weight/height2) showed that obese women had a 49% higher risk of dying from(More)
Breast cancer patients who are obese have a higher risk of lymph node metastases and a poorer prognosis than those who are slim. It has been claimed that estrogens derived from fat are important for these associations. If estrogens are important, these relationships must be stronger in the hormone receptor-positive than in the hormone receptor-negative(More)
Hormonal mechanisms have been offered as an explanation for the higher frequency of large tumours, lymph node metastases and poorer prognosis in obese breast cancer patients than in lean ones. If hormonal mechanisms are important for these relations, they should probably act more strongly in patients with hormonal receptor positive tumours than in those(More)
Both subtypes of estrogen receptor (ER), ERalpha and ERbeta, are normally present in the mammary gland. The role of ERalpha as a prognostic marker in breast cancer is well established due to the beneficial effect of providing tamoxifen as adjuvant therapy. The role of ERbeta, however, is less clear. To gain insight into the importance of ERbeta in breast(More)
BACKGROUND According to the new autopsy regulation from April 2004 the next to kin must be informed of an autopsy and the right to deny consent. The present study aims at documenting the impact of this regulation on the number of autopsies performed and to determine whether regular reminders and changed autopsy routines could reduce the time needed to(More)
