Tyrosine hydroxylase (TH)-positive neurons (TH neurons) were found in the pineal gland of golden hamsters. To examine possible relations between TH neurons and environmental light, we kept male animals under constant light (LL) and darkness (DD) for a week, and morphometrically compared the number, size, and immunoreactivity of TH neurons with those of(More)
The localization of pituitary adenylate cyclase-activating polypeptide (PACAP) in the hypothalamus-pituitary system in rats was examined in light and electron microscopic immunocytochemistry using a specific antiserum to synthetic PACAP 1-38 (R0831). In light microscopic study, intensely PACAP-immunostained perikarya were observed in the supraoptic and(More)
By in situ hybridization histochemistry, fibroblast growth factor receptor gene (flg)-expressing neurons were newly identified in the basal magnocellular nuclei (the vertical and horizontal limbs of the diagonal band, and Meynert's nucleus). The present study also confirmed flg localization in the laterodorsal tegmental nucleus and the pedunculopontine(More)
This study investigated the effects of segmented animated graphics utilized to facilitate learning of electrolysis of aqueous solution. A total of 171 Secondary Four chemistry students with two different spatial ability levels were randomly assigned to one of the experimental conditions: (a) text with multiple static graphics (MSG), (b) text with continuous(More)
Light and electron microscopic observation showed two types of neuronal immunostaining for basic fibroblast growth factor in the hippocampal CA2 subfield, where the densest immunoreactive neurons were localized in the brain. One neuronal type showed intense nuclear (eu- and heterochromatin) immunostaining but weak cytoplasmic immunostaining (N-type), and(More)
Using in situ hybridization histochemistry and observation with a double (dark and bright) illumination apparatus, the precise localization of preprosomatostatin mRNA was studied in the adult rat lower brainstem and cerebellum. It has previously been hard to localize the somatostatin precursor gene in the adult rat brainstem, because the level of expression(More)
Numerous cells containing P-450(F-1) were detected in the magnocellular and parvocellular neurons of the paraventricular nucleus of the hypothalamus. Electron microscopic analysis of immunoreactive neurons has shown that P-450(F-1) immunoreactivity is present on the Golgi apparatus and rough endoplasmic reticulum. In the paraventricular nucleus, the(More)
Atracurium and alcuronium have been compared during halothane anaesthesia, by measurement of the mechanical response of the adductor pollicis muscles to train-of-four stimulation and by clinical observation. Atracurium appeared significantly shorter-acting than alcuronium. However, results suggested that the action of alcuronium may not be of "medium(More)
