Impact of acupuncture by using life-energy (qi) oriental needle on the paralysis of rats with experimental autoimmune encephalomyelitis.

In acupuncture, adaptation to energy flows in body cycles is the key to health and therapy. From the evolution of our thinking about acupuncture, we developed the Life-Energy (Qi) oriental needle (Qi needle). It contains a rotating electromagnetic wave and has a strong affinity for the meridians.

Prevalence of depression and correlates of depressive symptoms for residents in the urban part of Jeju Island, Korea.

Aims: This study examined the prevalence of depression and depressive symptoms, and the correlates of depressive symptoms, and proposes some methods for reducing risk of depression in residents of the urban part of Jeju Island in Korea.

Methods: In all, 1050 residents were selected using multiphasic cluster sampling to represent each district. Of the 981 respondents, 413 were men and 568 were women.

Opuntia ficus-indica attenuates neuronal injury in in vitro and in vivo models of cerebral ischemia.

We examined whether the methanol extract of Opuntia ficus-indica (MEOF) has a neuroprotective action against N-methyl-d-aspartate (NMDA)-, kainate (KA)-, and oxygen-glucose deprivation (OGD)-induced neuronal injury in cultured mouse cortical cells. We also evaluated the protective effect of MEOF in the hippocampal CA1 region against neuronal damage evoked by global ischemia in gerbils. Treatment of neuronal cultures with MEOF (30, 300, and 1000 microg/ml) inhibited NMDA (25 microM)-, KA (30 microM)-, and OGD (50 min)-induced neurotoxicity dose-dependently.

Activation of embryonic intermediate filaments contributes to glial scar formation after spinal cord injury in rats.

The expression of two intermediate filaments, nestin and vimentin, was studied in spinal cord injury (SCI) to elucidate their roles in the formation of glial scars. Rats were sacrificed 1, 4, and 7 days after induction of compression injury of the spinal cord using an aneurysm clip. The affected spinal cords were studied using antibodies against nestin and vimentin intermediate filaments.

Histochemistry of six lectins in the tissues of the flat fish Paralichthys olivaceus.

Lectins are glycoproteins that specifically bind carbohydrate structures and may participate in the biodefense mechanisms of fish. In this study, the binding of three lectins, Dolichos biflorus agglutinin (DBA), soybean agglutinin (SBA), Bandeiraea simplicifolia BS-1 (isolectin B4), Triticum vulgaris (WGA), Arachis hypogaea (PNA) and Ulex europaeus (UEA-I) were studied in the gill, liver, intestine, kidney, heart, and spleen of the flat fish Paralichthys olivaceus. DBA was detected in intestinal mucous cells, as well as in gill epithelial and mucous cells.

Immunohistochemical localization of Bcl-2 in the spinal cords of rats with experimental autoimmune encephalomyelitis.

We examined the localization of the anti-apoptotic molecule Bcl-2 in the spinal cords of Lewis rats with experimental autoimmune encephalomyelitis (EAE). Western blot analysis showed that Bcl-2 was constitutively expressed in normal spinal cords, and weakly increased in response to complete Freund's adjuvant(CFA) immunization. In EAE, with infiltration of inflammatory cells into spinal cords, Bcl-2 declined during the peak stage and further decreased during the recovery stage.

Histochemical detection of glycoconjugates in the male reproductive system of the horse.

Lectins are glycoproteins of plant and animal origin that have the ability to bind specific carbohydrate residues of cell glycoconjugates, particularly in terminal positions. In this study, the binding of lectins, Dolichos biflorus agglutinin (DBA), soybean agglutinin (SBA), Bandeiraea simplicifolia BS-1 (isolectin B4), Triticum vulgaris (WGA), Arachis hypogaea (PNA), and Ulex europaeus (UEA-I), was studied in the reproductive systems of male thoroughbred horses.DBA was detected in the stereocilia of the caput and corpus epididymis, and in the vas deferens.

Histochemical characterization of the lectin-binding sites in the equine vomeronasal organ.

The binding specificities of various lectins, such as the Dolichos biflorus agglutinin (DBA), soybean agglutinin (SBA), and the Bandeiraea simplicifolia BS-1 (Isolectin B4), Triticum vulgaris (WGA), Arachis hypogaea (PNA), and Ulex europaeus (UEA-I) lectins, were studied in the vomeronasal organ of the horse. The microvilli of the vomeronasal sensory epithelium were positive for DBA, SBA, Isolectin B4, WGA, PNA, and UEA-I. The receptor cells showed intense reactivity for DBA and WGA.

Embryonic intermediate filaments, nestin and vimentin, expression in the spinal cords of rats with experimental autoimmune encephalomyelitis.

Intermediate filaments, including nestin and vimentin, are found in specific cell types in central nervous system (CNS) tissues, particularly immature glial cells and multipotent progenitor cells. In the present study, the expression patterns of nestin and vimentin in the spinal cords of rats with experimental autoimmune encephalomyelitis (EAE) and the response of cells containing filaments against acute autoimmune injury were examined by immunohistochemistry. Nestin immunostaining was only weakly detected in vascular endothelial cells but not in any cell types in the spinal cord in normal and adjuvant-immunized rats.
