JOURNAL FREE ACCESSWe compared morphometric data on various nerve cells in the human special sensory system using the modified Klüver-Barrera staining method with an extremely minimized shrinkage ratio and an image-analyzer. According to the measurement data of cell-body sizes, we classified nerve cells of the various nerve nuclei in the special sensory system into three groups. These data are of interest to better understand the process of nerve conduction in the special sensory system.View full abstractDownload PDF (157K) -

JOURNAL FREE ACCESSWe measured the cross-sectional area (CSA) of the human tractus solitarius (HTS) with the help of an image-analyzer system on a cross section of the upper part of the medulla oblongata in 44 Japanese cadavers (22 males and 22 females) and examined the relationship between age, sex and whether the subjects were dentulous or edentulous. The results showed no significant differences between the left and right sides of the HTS in either male or female subjects. However, the size of HTS decreased slightly with age in males but not at all in females, whereas tooth loss had a definite incidence on the size of HTS in females but not in male, as the CSA was smaller in edentulous females but not in edentulous males. This would tend to indicate that a decreases in taste function is connected with the aging process in male, and with tooth loss in females.View full abstractDownload PDF (112K) -

JOURNAL FREE ACCESSThe present study was undertaken to evaluate the effects of monocular enucleation on the calbindin-D 28k (CB) and c-Fos immunoreactive (IR) neurons in the lateral geniculate nucleus (LGN) complex of adult rats. The enucleation resulted in neuronal degeneration and decrease of neurons in the LGN complex. Our study demonstrated a decrease of CB-IR neuronal density on the contralateral side of the ventral (vLGN) and dorsal LGN (dLGN) until 12 weeks post-enucleation (PE). On the ipsilateral side, CB-IR neuronal density in the dLGN and vLGN showed significant and continuous decrease until 48 and 12 weeks PE, respectively. In an additional experiment, c-Fos-IR neurons were increased at 2 days PE in the vLGN with ipsilateral predominance. At 7 days, c-Fos-IR neurons on the ipsilateral vLGN were still higher than those of pre-enucleated rats. The present results suggest that monocular enucleation affects the expression of the CB and c-Fos in the LGN complex. It is indicated that these may play an important role in the neuronal degeneration and neuroplasticity of the subvisual system in rats.View full abstractDownload PDF (444K) -

JOURNAL FREE ACCESSWe describe pathological, ultrastructural, and spectrographic analyses of surgically resected cornea from a man with atypical corneal opacification, and discuss the corneal pathogenesis, and the utility of energy-dispersive X-ray microanalysis (EDXA).
The histopathologic features of a case presenting with longstanding bilateral corneal clouding are reported, which was difficult to be diagnosed clinically as calcific band keratopathy. The patient underwent keratoplasty on his right eye. Paraffin sections of the host corneal button were subjected to hematoxylin and eosin (H&E). An adjacent section was studied by means of EDXA. Plastic sections were observed under a transmission electron microscope (TEM). H&E staining revealed flattened corneal epithelial cells and disappearing Bowman's membrane accompanied by numerous basophilic granular deposits within the underlying corneal stroma. EDXA demonstrated the elevated peaks of calcium and phosphorus within the area of granular deposits. TEM revealed electron dense material consistent with extracellular calcospherites. Given the patient's past medical and family history, and the serologic test results, the clinical presentation and histological findings were most consistent with calcific band keratopathy associated with preexisting minimal syphilitic keratitis. Extensive histologic studies including EDXA on resected corneal tissue can be helpful for the differential diagnosis and may elucidate the pathogenesis of corneal diseases.View full abstractDownload PDF (216K) -
- Relation to Tenosynovectomy -Naoki SHIRAISHI, George MATSUMURA2005 Volume 82 Issue 1 Pages 25-30

JOURNAL FREE ACCESSSufficient improvement in De Quervain disease, is not always archieved even by tenosynovectomy, and the reason for this appears to be anatomical variation in the first extensor compartment of the hand.
In this study we examined the first extensor compartment of 159 hands of 80 human cadavers. Hiranuma and colleagues documented four anatomical types of first compartment, and in this study type A was observed in 76 (47.8%) of the 159 hands, type B in 49 (30.8%), and type C in 21 (13.2%). No type D compartments in which the extensor pollicis brevis tendon is absent, were observed. There were 13 hands that did not fit any of Hiranuma's categories, and we classified them into three new types: E, F, and G.
The numbers of extensor pollicis brevis tendons in the first compartment varied from one to three, and the number of abductor pollicis longus tendons varied from one to seven.
Successful tenosynovectomy in the treatment of De Quervain disease requires to pay close attention to accessory tendons of the extensor pollicis brevis tendon and abductor pollicis longus tendon, branching of the tendons, and the presence of an atypical septum in the first compartment.View full abstractDownload PDF (195K)
