The basic cellular lesion in CNS of suckling rats treated with Pexid was studied by light and electron microscopy. The most pronounced abnormality, the formation of various intracytoplasmic inclusions, was found in neurons, astrocytes, oligodendrocytes, ependymal cells, endothelial cells and fibroblasts. These abnormal inclusions were generally(More)
BACKGROUND Minocycline prevents the development of neuropathic and inflammatory pain by inhibiting microglial activation and postsynaptic currents. But, how minocycline obviates acute visceral pain is unclear. The present study investigated whether minocycline had an any antinociceptive effect on acetic acid-induced acute abdominal pain after(More)
BACKGROUND Punica granatum (pomegranate) is kind of a fruit consumed fresh or in beverage. It has been widely used in traditional medicine in various parts of the world. In this study, we examined the efficacy of a Punica granatum (PG) extract in protecting skin against UVB-induced damage using cultured human skin fibroblasts. METHODS A Korean red PG(More)
Ultraviolet (UV) light is a physical carcinogen, and UV irradiation from sunlight has negative effects on human skin. UVB-induced inflammation is linked to excessive induction of various inflammatory cytokines/chemokines in many types of cells, including keratinocytes. The purpose of this study was to investigate the anti-inflammatory effect of water(More)
ETHNOPHARMACOLOGICAL RELEVANCE Xanthii fructus (XF) has long been used to treat a variety of inflammatory conditions in Korean traditional medicine, but the underlying mechanisms that could explain the anti-inflammatory actions of XF remain largely unknown. AIM OF THE STUDY This study aimed to elucidate the anti-inflammatory effects of X. fructus (XF) and(More)
Ultrastructural features of epidermoid cysts in the spinal leptomeninges were studied in two strains of mouse. Although the cysts were lined by stratified squamous epithelium, the normal sequence of epidermal differentiation in this epithelium was not observed in that the basal cell layer was absent in certain areas. The morphological features and genesis(More)
Although many agents for acute ischemic stroke treatment have been developed from extensive preclinical studies, most have failed in clinical trials. As a result, researchers are seeking other methods or agents based on previous studies. Among the various prospective approaches, vascular protection might be the key for development of therapeutic agents for(More)
BACKGROUND Ethyl pyruvate (EP) possesses anti-inflammatory activity. However, the potential anti-nociceptive value of EP for the treatment of the inflammatory nociception is largely unknown. We investigated whether EP could have any anti-nociceptive effect on inflammatory pain, after systemic administration of EP (10, 50, and 100 mg/kg, i.p.), 1 hour before(More)
Lithospermi radix (LR, Borraginaceae, the root of Lithospermum erythrorhizon Siebold. et Zuccarinii) is used in herbal medicine to treat such conditions as eczema, skin burns and frostbite. This study investigates the effects of LR on the anti-allergy mechanism. LR inhibited the release of histamine from rat peritoneal mast cells by compound 48/80 in a(More)
