Cyclooxygenase-2 is the rate-limiting enzyme in synthesis of prostaglandins and other eicosanoids. Prior reports have shown that inhibition of cyclooxygenase-2 activity, either by selective inhibitors or by antisense oligonucleotide, results in suppression of growth of squamous cell carcinoma cell lines which express high cyclooxygenase-2 levels, such as(More)
Although many studies have indicated that electroacupuncture (EA) provides a neuroprotective effect against ischemic brain damage, the protective mechanism is not fully understood. Glutamate release and hippocampal blood flow in ischemia with EA were investigated to elucidate the neuroprotective mechanism of EA. Transient 5-minute ischemia was induced in(More)
Cisplatin (CDDP) and 5-fluorouracil (5-FU) are common anti-tumour agents, and the anti-tumour effect of CDDP and 5-FU are synergistically enhanced by combined treatment. To clarify the mechanisms of this synergism, we examined the effect of CDDP and 5-FU on the expression of cell adhesion molecules involved in recognition of cancer cells by T lymphocytes.(More)
