The mu opioid receptor gene (MOR) was mutated in mice by a gene targeting procedure. In these MOR-knockout mice, the analgesic effects of morphine, its major metabolites, morphine-6-glucuronide (M-6-G) and morphine-6-ethereal sulfate (M-6-S), and endomorphin-2, as well as morphine-induced lethality, were drastically reduced, whereas the effects of DPDPE and(More)
Mitochondrial ATP-sensitive potassium (mitoK(ATP)) channels have been suggested as triggers and end effectors in myocardial ischemic preconditioning. However, the intracellular mechanism regulating mitoK(ATP) channels remains unclear. In the present study, mitoK(ATP) channels from bovine ventricular myocardium were reconstituted using planar lipid bilayers,(More)
In the present study, we extracted Angelica pubescens (AP) with various solvents in order to find the bioactive constituents that demonstrated analgesic and anti-inflammatory effects. The results were obtained as follows: (1) Methanol-, chloroform-, and ethyl acetate-extracts effectively reduced the pain that was induced by 1% acetic acid and a hot plate.(More)
This two-stage epidemiologic study was to investigate the prevalence and types of dementia among elderly people in the Saa-Min district of Kaohsiung City in Taiwan. In stage one, the Chinese Mini-Mental Status Examination (CMMSE) and Blessed Dementia Rating Scale were employed. In stage two, a comprehensive neurobehavioral examination and neuropsychologic(More)
The current study examined the effects of bosentan, an orally active antagonist of endothelin-A and -B receptors, on the development and maintenance of hypoxia (10% O2)-induced pulmonary hypertension and vascular remodeling in the rat. Pretreatment with bosentan (100 mg.kg-1.day-1, 1 gavage/day for 2 days) completely blocked the pulmonary vasoconstrictor(More)
BACKGROUND Vascular disease progresses more slowly in females with functional ovaries than in males. The mechanisms of this vasoprotective effect of female sex are incompletely understood. This study tested (1) whether there is a sex difference in the development of myointimal proliferation after balloon injury of the rat carotid artery in vivo, (2) whether(More)
Intact male and female spontaneously hypertensive rats showed a progressive increase in blood pressure with growth; male attained systolic blood pressure levels of 244 +/- 6 mmHg, and females 205 +/- 3 mmHg at age 22 weeks. Orchidectomy at age 4 weeks significantly attenuated the systolic blood pressure elevation in the male (195 +/- 4 mmHg at age 22(More)
BACKGROUND Kimura disease, often accompanied by nephrotic syndrome, is a rare, chronic inflammatory disorder of unknown cause. In this report, the clinical and histopathological characteristics of 20 Chinese patients with Kimura disease-associated nephrotic syndrome were retrospectively evaluated. METHODS We report a case of Kimura disease that was(More)
Approximately 70% of the initial ferriprotoporphyrin IX polymerizing activity in cell-free preparations of erythrocytes infected with Plasmodium berghei was recovered in a chloroform extract. No polymerizing activity remained in the residue. In studies to identify substances that promote FP polymerization, arachidonic, linoleic, oleic, and palmitoleic(More)
The selective endothelin-A (ETA)-receptor antagonist BQ-123 has been shown to prevent chronic hypoxia-induced pulmonary hypertension in the rat. Therefore in the current study we utilized BQ-123 to test the hypothesis that blockade of the ETA receptor can reverse as well as prevent the increase in mean pulmonary artery pressure, right ventricle-to-left(More)
