Behavioral experiments using ablation of the hippocampus are increasingly being used to address the hypothesis that the avian hippocampus plays a role in memory, as in mammals. However, the morphological basis of the avian hippocampus has been poorly understood. In the present study, the afferent and efferent connections of the hippocampus in the pigeon(More)
In the present study, we investigated the immunohistochemical localization of two-pore K(+)-channels TASK-1, TASK-2, TASK-3 and TRAAK in the rat carotid body. Type I cells were positive for TASK-1, TASK-2, TASK-3 and TRAAK. Intrinsic nerve cell bodies were also strongly positive for TASK-1, TASK-2 and TRAAK, but negative for TASK-3. In addition, some type(More)
The aim of the present study was to define the age-related changes in sensory and secretomotor nerve endings in the larynx of F344/N rats. For this purpose, laryngeal tissue sections obtained from 12-, 24- and 35-month-old F344/N rats were compared with respect to the density, distribution and morphology of various types of sensory and secretomotor nerve(More)
PURPOSE To compare the expression pattern of cyclooxygenase-2 (COX-2) in rabbit corneal cells after photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) with the same refractive correction. SETTING Department of Ophthalmology, Wakayama Medical University, Wakayama, Japan. METHODS Thirty adult albino rabbits were used in the study.(More)
PURPOSE To compare the wound-healing process in the rabbit cornea after photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) with the same refractive correction. SETTING Department of Ophthalmology, Wakayama Medical University, Wakayama, Japan. METHODS Adult albino rabbits (N = 24) were used. One eye of each animal had PRK or LASIK(More)
Numerous studies have demonstrated a correlation between hyaluronan expression and the malignant properties of various kinds of cancer, and inhibition of hyaluronan production causes decreased tumor growth. Hyaluronan oligosaccharides have been shown to inhibit several tumor cell types via disruption of receptor-hyaluronan interaction. However, few studies(More)
It is difficult to differentiate some malignant peripheral nerve sheath tumors (MPNST) from benign peripheral nerve sheath tumors (BPNST) histologically, and to predict the clinical outcome of patients with MPNST. In this study, the expression of VEGF and MVD were evaluated immunohistochemically in 22 cases of MPNST, 14 of neurofibroma and 19 of schwannoma(More)
Very little is known about esophageal innervation in the hamster. In the present study, we used protein gene product 9.5 (PGP 9.5) to determine immunohistochemically the architectural features of the enteric nervous system in the hamster esophagus. The myenteric plexus consisted of a loose and irregular network of ganglia and interganglionic nerve bundles.(More)

This study investigated the morphological changes of lungs in F344/N rats (9-36 months old). We initially examined general and quantitative morphological changes, and then we used immunohistochemistry to detect distributional changes in collagen subtypes (types I, III, and IV) and smooth muscle cell (SMC) markers (alpha-smooth muscle actin (ASMA),(More)
