We studied the distribution of vasoactive intestinal polypeptide-like immunoreactive (VIPLI) fibers in the central amygdaloid (AC) nucleus of the rat, using indirect immunofluorescence and the origins of such fibers using a combination of retrograde tracing with immunocytochemistry. VIPLI fibers formed a dense fiber plexus in the lateral subdivision of the(More)
House dust mite (HDM) is a primary allergen in allergic rhinitis (AR) and asthma. Neutrophil apoptosis is associated with allergic diseases and innate immunity to infection. The present study examined how HDM affects constitutive neutrophil apoptosis in normal and AR subjects. Total IgE increased in AR subjects when compared to normal subjects, and patients(More)
Parkinson’s disease (PD) is a neurodegenerative disorder characterized by loss of dopaminergic neurons in the substantia nigra pars compacta. In this study, we investigated the effects of a novel herb formula, Hepad, on PD. Dose-dependent treatment with 1-methyl-4-phenylpyridinium (MPP+) decreased the viability of SH-SY5Y cells, and Hepad inhibited the(More)
House dust mites (HDMs) induce allergic diseases such as asthma. Neutrophil apoptosis is an important process of innate immunity, and its dysregulation is associated with asthma. In this study, we examined the effects of HDM on constitutive apoptosis of normal and asthmatic neutrophils. Extract of Dermatophagoides pteronissinus (DP) inhibited neutrophil(More)
Although extract of Dermatophagoides farinae (DF) alone had no effect on neutrophil apoptosis, it inhibited neutrophil apoptosis in neutrophils cocultured with lymphocytes in both normal and allergic subjects. DF showed a stronger inhibition on the apoptosis of allergic neutrophils cocultured with allergic lymphocytes than that of normal neutrophils(More)
House dust mite is a major allergen in allergic diseases such as asthma. In this study, we investigated the effects of house dust mite on constitutive eosinophil apoptosis in normal and asthmatic subjects. We classified asthmatic subjects into those with atopic and non-atopic asthma depending on the presence of DP-specific IgE or/and DF-specific IgE in(More)
Calcitonin gene-related peptide (CGRP) and substance P (SP)-immunoreactive (IR) axons in the nucleus gracilis of normal rats (1-15 months of age) were studied by light and electron microscopy. Besides many CGRP-IR and SP-IR varicosities with normal appearance, we found a few swollen (nearly round or oval) varicosities with either CGRP or SP(More)
