Permanent increase of immunocytochemical reactivity for γ-aminobutyric acid (GABA), glutamic acid decarboxylase, mitochondrial enzymes, and glial fibrillary acidic protein in rat cerebral cortex damaged by early postnatal hypoxia-ischemia

Autor: A. W. J. W. Janszen, H. J. Romijn, C. Van Den Bogert

Publikováno v: Acta Neuropathologica. 87:612-627

A former study indicated that hypoxic-ischemic encephalopathy in rat sustained during early postnatal life may result in permanent epileptic activity in the baseline electroencephalogram. We, therefore, investigated whether the presumed higher firing

Parasympathetic and sympathetic control of the pancreas: a role for the suprachiasmatic nucleus and other hypothalamic centers that are involved in the regulation of food intake

Autor: R M, Buijs, S J, Chun, A, Niijima, H J, Romijn, K, Nagai

Publikováno v: The Journal of comparative neurology. 431(4)

To reveal brain regions and transmitter systems involved in control of pancreatic hormone secretion, specific vagal and sympathetic denervation were combined with injection of a retrograde transsynaptic tracer, pseudorabies virus (PRV), into the panc

Anatomical and functional demonstration of a multisynaptic suprachiasmatic nucleus adrenal (cortex) pathway

Autor: R M, Buijs, J, Wortel, J J, Van Heerikhuize, M G, Feenstra, G J, Ter Horst, H J, Romijn, A, Kalsbeek

Publikováno v: The European journal of neuroscience. 11(5)

In view of mounting evidence that the suprachiasmatic nucleus (SCN) is directly involved in the setting of sensitivity of the adrenal cortex to ACTH, the present study investigated possible anatomical and functional connections between SCN and adrena

Immunocytochemical evidence for a diurnal rhythm of neurons showing colocalization of VIP with GRP in the rat suprachiasmatic nucleus

Autor: H J, Romijn, A A, Sluiter, J, Wortel, J F, Van Uum, R M, Buijs

Publikováno v: The Journal of comparative neurology. 391(3)

The suprachiasmatic nucleus (SCN), which functions as a biological clock, contains several neuropeptides such as vasoactive intestinal peptide (VIP), peptide histidine isoleucine (PHI), and gastrin-releasing peptide (GRP). Studies from several labora

Differences in colocalization between Fos and PHI, GRP, VIP and VP in neurons of the rat suprachiasmatic nucleus after a light stimulus during the phase delay versus the phase advance period of the night

Autor: H J, Romijn, A A, Sluiter, C W, Pool, J, Wortel, R M, Buijs

Publikováno v: The Journal of comparative neurology. 372(1)

Two groups of four rats each received a 15-minute light stimulus during the first part of the night (ZT14) and the second part (ZT19), respectively. After 45-60 minutes, the animals were killed by perfusion fixation. Adjacent Vibratome sections throu

Electron microscopy of the rabbit pineal organ in vitro

Autor: A. J. Gelsema, H. J. Romijn

Publikováno v: Cell and Tissue Research. 172:365-377

The results presented in this study show that the rabbit pineal organ cultured in vitro retained its in vivo fine structure for at least eight days. However, the Golgi complex in the light pinealocytes stopped forming dense core vesicles while vesicl

The ultrastructure of the rabbit pineal gland after sympathectomy, parasympathectomy, continuous illumination, and continuous darkness

Autor: H. J. Romijn

Publikováno v: Journal of neural transmission. 36(3-4)

The ultrastructure of the rabbit pineal gland was investigated after sympathectomy (extirpation of decentralization of the superior cervical ganglia), parasympathectomy, continuous illumination and continuous darkness. The similarity of the ultrastru

Postembedding immunocytochemical GABA labeling in rat neocortex cultures: applicability in quantitative studies

Autor: H J Romijn, R M Buijs, de Bauke Jong

Publikováno v: Neuroscience Letters, 75, 23-30. Elsevier Ireland Ltd

The value of γ-aminobutyric acid (GABA) immunogold labeling in the quantification of nerve endings was studied in dissociated rat neocortex cultures. Adjacent sections were processed in 3 series according to the same staining protocol. Of all nerve
