Dipole analysis of epileptic source generator with manual zero potential shifting method.

The dipole tracing method is a technique whereby an electric source generator is estimated as an equivalent current dipole (ECD) based on potential distribution on the scalp. To estimate the electric source generator of low amplitude spikes, a manual zero potential shifting (MZPS) method was introduced in which a zero potential is set manually in dipole analysis. The subjects were three patients with localization-related epilepsy with temporal spikes.

Relationship between ultrasonically nebulized distilled water-induced bronchoconstriction and acetic acid-induced cough in asthmatic children.

Background: Although wheezing and cough are the most common complaints in asthmatic persons, the mechanisms of hyperresponsiveness to bronchoconstriction and cough are nevertheless still unclear.

Objective: To investigate the common mechanisms between them, we studied the relationship between ultrasonically nebulized distilled water (UNDW) inhalation challenge and acetic acid (AA) inhalation challenge. In addition, we evaluated the effect of inhaled furosemide on both provocation tests by means of a placebo-controlled study.

Inhaled indomethacin prevents bronchoconstrictive response to distilled water but not to histamine in children with asthma.

We evaluated the effect of inhaled indomethacin, a nonsteroidal antiinflammatory drug (NSAID), against bronchoconstriction induced by ultrasonically nebulized distilled water (UNDW) in children with asthma. Ten children with asthma (eight males and two females, with a mean +/- SEM age of 10.7 +/- 0.

Clinical and immunologic surveys of Hymenoptera hypersensitivity in Japanese forestry workers.

Background: The increased incidence of bee-sting allergy among beekeepers is well known, whereas Hymenoptera hypersensitivity among forestry workers, who are frequently stung by Hymenoptera, is not well understood.

Objective: To elucidate the nature of Hymenoptera hypersensitivity among forestry workers and analyze the mechanism involved in Hymenoptera-induced systemic reactions.

Methods: A questionnaire was administered and yellow jacket venom-specific IgE antibody titers measured in 323 forestry workers and 100 age-matched office workers with little occupational exposure to Hymenoptera stings as a control group.

Inhaled diuretics attenuate acid-induced cough in children with asthma.

To evaluate the effect of inhaled diuretics, furosemide and amiloride, on cough induced by acid inhalation challenge in asthmatic children, a double-blind, randomized, placebo-controlled study was conducted. On separate days, 12 asthmatic children (10.3 +/- 0.
