Glioma prostaglandin levels correlate with brain edema. Journal of Tongji Medical University = Tong ji yi ke da xue xue bao, 1998, Volume: 18, Issue:2 The present study was designed to prospectively investigated the prostaglandin (PG) levels and extent of peritumoral edema in 30 cases of glioma by using methods of radioimmunoassay and imaging. Both TXB2 and 6-keto-PGF1 alpha levels in all glioma groups went up over that in the control group. TXB2 level and ratio of TXB2/6-keto-PGF1 alpha were markedly increased with the extent of tumor malignancy. Water concentration in anaplastic astrocytoma and glioblastoma were significantly elevated. Difference in TXB2 level and TXB2/6-keto-PGF1 alpha ratio among three edema grades were statistically significant. TXB2 level and ratio of TXB2/6-keto-PGF1 alpha were closely correlated with water concentration (r1 = 0.53, r2 = 0.72, P < 0.01). Our findings suggested that the metabolism of PG in glioma were in the state of disorder, and that the imbalance between PGI2 and TXA2 may be one of factors which affect the formation of peritumoral edema.

Production of prostaglandins and thromboxane by isolated cells from intracranial tumours. Journal of neurology, neurosurgery, and psychiatry, 1984, Volume: 47, Issue:6 Tumour cell-rich platelet-free preparations were isolated from 21 fresh samples of human intracranial tumours using enzymic digestion, followed by discontinuous density gradient centrifugation on Percoll and (14 preparations) adherence on plastic. Of the disaggregated cells 79.8 to 97.7% (mean 86.2%) were tumour cells, and mean cell viability was 82.6%. All the tumours produced prostaglandin (PG), E2, F2 alpha, 6 oxo F1 alpha and Thromboxane B2 during 16 hours of incubation but the amount varied widely. Highest production of PGE2 and TXB2 per 10(5) cells was by the eight meningiomas in which the prostanoid profile closely resembled that of circulating monocytes.
