Intimal asteroid bodies in horses: light and electron microscopic observations.

Ultrastructure and composition of asteroid bodies.

PURPOSE Asteroid hyalosis is a disease of the vitreous, characterized by brilliant reflecting particles, termed asteroid bodies, which are surrounded by a tightly adhering network of fibrils. The composition and mode of formation of asteroid bodies is not yet understood in detail. The purpose of this study was to investigate the ultrastructure of asteroid bodies and to identify the intrinsic in...

Syntaxin 1 is expressed in the trout saccular hair cells: RT-PCR and immunocytochemical observations

Syntaxin is one of several proteins that may be involved in the docking of synaptic vesicles, synaptic vesicle recycling, and non-synaptic membrane trafficking. Presence of syntaxin has been reported in rat auditory and vestibular end organs. In the current study, we have examined the expression of message for syntaxin 1 in hair cells of the sacculus of the rainbow trout, Oncorhynchus mykiss, w...

Light and electron microscopic study of the tongue in the White-eared bulbul (Pycnonotus leucotis)

The aim of the present study was to investigate the light and electron microscopic structure of the tongue in White-eared bulbul (Pycnonotus leucotis). Six adult White-eared bulbul (3 males and 3 females) in Shahrekord district were used in the investigation. Samples of the apex, body and root of the tongue were prepared routinely for light and electron microscopic study. Results showed that th...

Electron Microscopic Observations on the Blood of the Horse I : Neutrophils in the Peripheral Blood of the Clinically Healthy Horses

The Nature of Asteroid Surfaces, from Optical Polarimetry

Telescopic observations of the polarization of light by asteroids are interpreted on the basis of a systematic polarimetric analysis of terrestrial, meteoritic and lunar samples. Laboratory measurements were made using samples with different surface textures, and scanning electron microscope pictures were used to investigate the influence of microtexture and crystalline structure. It is demonst...
