Equal doses (8 mg/kg) of the nonsteroidal antiinflammatory drugs indomethacin, naproxen, and sulindac and a large dose of sulindac (32 mg/kg) were administered intragastrically to conscious rats after a normal sodium diet, furosemide stimulation, and a low sodium diet for 8 days. Indomethacin, naproxen, and the high dose sulindac (32 mg/kg) decreased urinary prostaglandin E2 excretion significa...
The fruit hull of mangosteen, Garcinia mangostana L. has been used as a Thai indigenous medicine for many years. However, its mechanism of action as a medicine has not been elucidated. The present study was undertaken to examine the effects of mangosteen extracts (100% ethanol, 70% ethanol, 40% ethanol and water) on histamine release and prostaglandin E2 synthesis. We found that the 40% ethanol...
It is suggested that COVID-19 (coronavirus) and other enveloped viruses can be inactivated by bioactive lipids. Bioactive lipids (BALs) AA, gamma-linolenic acid (GLA), dihomo-GLA (DGLA), eicosapentaenoic (EPA), docosahexaenoic (DHA) are precursors to anti-inflammatory metabolites prostaglandin E1, lipoxin A4, resolvins, protectins maresins enhance phagocytosis of macrophages leukocytes clear de...
Osteoid osteoma is a benign bone tumor characterized by local pain that typically increases at night. The tumor commonly occurs in the long bones of the lower extremities, and in rare instances in cranial bones. Here we report the case of a 25-year-old man diagnosed with an osteoid osteoma of the right occipital condyle. The patient suffered from severe occipital pain in the 3 years leading up ...
Leukoencephalopathies are a group of white matter disorders related to abnormal formation, maintenance, and turnover of myelin in the central nervous system. These disorders of the brain are categorized according to neuroradiological and pathophysiological criteria. Herein, we have identified a unique form of leukoencephalopathy in seven patients presenting at ages 2 to 4 months with progressiv...
BACKGROUND The acylethanolamides oleoylethanolamide and palmitoylethanolamide are endogenous lipid mediators with proposed neuroprotectant properties in central nervous system (CNS) pathologies. The precise mechanisms remain partly unknown, but growing evidence suggests an antiinflammatory/antioxidant profile. METHODS We tested whether oleoylethanolamide/palmitoylethanolamide (10 mg/kg, i.p.)...
Current knowledge on prostaglandin biosynthesis is reviewed, centering on how PGs participate in the regulation of vascular tone and the prevention of platelet deposition on endothelial surfaces. Discussion includes review of the vasoactivity of the PG endoperoxides, thromboxane, prostacyclin, and prostaglandin E2; prostaglandin-catabolizing enzymes; polyunsaturated fatty acid precursors; nutri...
A number of wogonin derivatives have been synthesized as congeners of wogonin and evaluated for their inhibitory activities of PGE2 production. Wogonin derivatives modified at the B ring of wogonin were obtained from 2,4-Dihydroxy-3,6-dimethoxyacetophenone (1) via several steps. Most wogonin derivatives exhibited much reduced inhibitory activities against COX-2 catalyzed PGE2 production compare...
