Morphological and phenotypical diversity of eosinophils in the rat ileum
Eosinophils are abundantly present in intestinal mucosa. However, the morphological characteristics of their cellular population are still largely unknown. In this study, we examine theirExpand

Ultrastructural and Histochemical Study on the Paneth Cells in the Rat Ascending Colon
Paneth cells (PCs) contribute to the host defense against indigenous bacteria in the small intestine. We found Paneth cell‐like cells (PLCs) in the rat ascending colon, but the nature of PLCs isExpand

Immunohistochemical analysis of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) toxicity on the developmental dentate gyrus and hippocampal fimbria in fetal mice
Dioxins are widespread persistent environmental contaminants with adverse impacts on humans and experimental animals. Behavioral and cognitive functions are impaired byExpand

Ontogenic and morphological study of gonadal formation in genetically-modified sex reversal XYPOS mice
Mammalian sexual fate is determined by the presence or absence of sex determining region of the Y chromosome (Sry) in the “bipotential” gonads. Recent studies have demonstrated that both male andExpand

Peculiar Composition of Epithelial Cells in Follicle-Associated Intestinal Crypts of Peyer’s Patches in the Rat Small Intestine
ABSTRACT The epithelial cell composition was investigated in the follicle-associated intestinal crypt (FAIC) of rat Peyer’s patches. The epithelium of the FAIC mainly consisted of columnar epithelialExpand

Ultrastructural and Immunohistochemical Study on the Lamina Propria Cells Beneath Paneth Cells in the Rat Ileum
Paneth cells secrete bactericidal substances in response to bacterial proliferation on the mucosal surface without directly contacting bacteria. However, the induction mechanism of this transientExpand

Ultrastructural study on the morphological changes in indigenous bacteria of mucous layer and chyme throughout the rat intestine
Indigenous bacteria in the alimentary tract are exposed to various bactericidal peptides and digestive enzymes, but the viability status and morphological changes of indigenous bacteria are unclear.Expand

Differential expression of Toll-like receptor-2, -4 and -9 in follicle-associated epithelium from epithelia of both follicle-associated intestinal villi and ordinary intestinal villi in rat Peyer’s
The expressions of Toll-like receptor (TLR) -2, -4 and -9 were immunohistochemically investigated in the follicle-associated epithelium (FAE), and epithelia of the follicle-associated intestinalExpand

Mechanism of M-cell differentiation accelerated by proliferation of indigenous bacteria in rat Peyer’s patches
The mechanism by which indigenous bacteria on the follicle-associated epithelium (FAE) of lymphatic follicles (LFs) accelerate the differentiation of microvillous columnar epithelial cells (MV) intoExpand

Immunohistochemical study on the secretory host defense system with lysozyme and secretory phospholipase A2 throughout rat respiratory tract
The host defense system with lysozyme and secretory phospholipase A2 (sPLA2) was immunohistochemically investigated in rat respiratory tract under healthy conditions. In the nasal epithelium, a largeExpand
