...J.H. Baert; A.I. Viaene; R.J. Veys In this hybridohistochemical study, we investigated the expression of cytokeratin (CK) mRNA in the keratinizing squamous epithelium of hamster cheek pouch and esophagus, using eight different digoxigenin-labelled RNA probes complementary to human CK mRNAs. CK 4...

...D. Hartmann; M. Frotscher; J. Sievers We have analyzed the development of the major afferent and efferent connections of the hamster dentate gyrus as well as the morphology of its granule cells, subsequent to a novel developmental defect. Following the selective destruction of the overlying...

...P. van den Steen; A. van Lommel; J.M. Lauweryns Morphology and distribution of epithelial foot processes (FP) were studied in hamster neonatal lung bronchioles. To correlate them with growth, bronchiolar mitotic index was determined, rat small intestine used as a reference tissue...

...P. van den Steen; A. van Lommel; J.M. Lauweryns In studying epithelio-stromal interactions in the neonatal hamster lung, basal centrioles, basal cilia and open-ring centrioles attracted our attention. The same structures are also found in bronchiolar epithelium of a 3-week-old fawn-hooded rat...

...A. Krishna; P.F. Terranova Ovaries from hamsters on each day of the oestrous cycle at 09.00 h were observed for the number of mast cells, the pattern of mast cell degranulation, histamine concentration and blood flow. On day 4 (pro-oestrus), ovaries were also observed at 9.00,15.00 and 21.00 h...

...S. Shoumura; S. Emura; M. Utsumi; H. Chen; T. Yamahira; D. Hayakawa; A. Tamada; K. Terasawa; M. Arakawa; H. Isono The ultrastructure of the parathyroid glands of golden hamsters subjected to 5-gravity environment after administration of epinephrine was studied. In the epinephrine-treated animals...

...M. Schreckenberger; S. Reuss The Harderian gland of the Djungarian hamster Phodopus sungorus was investigated by light and electron microscopy in adult animals of both sexes, held under either long or short photoperiods. These glands have a tubuloalveolar structure. Epithelial cells were seen...

...C. Sunderkötter; W. Wittkowski; K. Hoffmann† The ventral sebaceous gland of the Djungarian hamster is a macroscopically visible organ situated in the midventral area of the abdominal wall. It consists of densely packed acini arranged in lobules with common excretory ducts. The rich vascular network...

...Aldona Kasprzak; Gastone G. Nussdorfer; Ludwik K. Malendowicz Sham-operated and unilaterally adrenalectomized male and female hamsters were administered 25 µ g adrenocorticotropic hormone (ACTH) for 5 days after the operation in order to examine the effects of ACTH on compensatory adrenal growth...

...S. Shownura; S. Emura; M. Utsumi; T. Yamahira; D. Hayakawa; K. Terasawa; A. Tamad; M. Arakawa; H. Isono The ultrastructure of the parathyroid glands of phosphate-treated golden hamsters exposed to a 5- G environment was studied. In the phosphate-treated animals exposed to a hypergravity environment...

...Norihiko Ihara; Shuichi Ueda; Mitsuhiro Kawata; Yutaka Sano The distributional pattern of serotonin-immunoreactive nerve fibers in the hippocampal formation of six different mammalian species (rat, chipmunk, hamster, cat, dog and monkey) was studied in detail by means of a modified peroxidase...

...B. Fernández; L. Suárez; M.A. Perez-Batista; I. Azcoitia; G. Bodega The ultrastructure of neurons of the diffuse supraoptic nucleus of the hamster has been studied. These neurons show two specializations of the endoplasmic reticulum: annulate lamellae and whorl bodies. From one to three whorl...

...Shizuko Shoumura; Shoichi Emura; Noriko Ishizaki; Tomo Yamahira; Huayue Chen; Hideo Isono The immunocytochemical localization of parathyroid hormone was examined in the hamster parathyroid gland by using the protein A-gold technique. Protein A-gold particles were concentratedover secretory granules...

...Shizuko Shoumura; Shoichi Emura; Noriko Ishizaki; Tomo Yamahira; Huayue Chen; Masaki Ito; Hideo Isono The ultrastructure of the parathyroid glands of hamsters subjected to 5 g environment after an intra-peritoneal injection of isoproterenol was studied. In the isoproterenol-treated hamsters exposed...

...Jan-Olof Johansson The scleral lamina cribrosa in the eyes of adult rats, hamsters, gerbils and guinea pigs was examined by ordinary histology and by scanning electron microscopy after soft tissue digestion. The complexity of the lamina, when mounted for scanning electron microscopy, was graded...

...Ned Buyukmihci; Faye Goehring-Harmon The retinal pigment epithelium of normal adult golden Syrian hamsters was examined by light and electron microscopy, using conventional and enzyme histochemical techniques. Hamster retinal pigment epithelium was composed of a single layer of cuboidal cells...

...Anand P. Chaudhry; Ravindra M. Shah Closure between the secondary palate and the primary palate and between the former and the nasal septum was studied in the Syrian golden hamster at light- and electron-microscopic level. Sequential changes in the epithelia before, during and after the closure...

...R.L. Miller; A.P. Chaudhry An ultrastructural developmental study of hamster vallate taste buds was undertaken to demonstrate the sequential morphodifferentiation of their various cellular components. Under the neurogenic influence of the glossopharyngeal nerve, the undifferentiated epithelial...

...Doris Ogrowsky; James Fawcett; Jürgen Althoff; Richard B. Wilson; Parviz Pour The Syrian hamster is a suitable animal model for the study of pancreatic neoplasms of ductal origin. Therefore, the present study was performed to obtain basic information on the pancreas of this species in neonatal life...

...R.L. Miller; A.P. Chaudhry A fine-structure study of the hamster fungiform, foliate and vallate taste buds was undertaken for comparative purposes. All three taste bud types shared in common composition of the dark cells, light cells, basal cells, nerve fibers and nerve endings and undifferentiated...
