Telepathology systems will be common systems in hospitals. The two systems were designed and implemented in web environments for test. One was implemented with the Common Object Request Broker Architecture (CORBA) technique. The other system was implemented in the form of ActiveX. The histopathological materials were stained by Hematoxylin and Eosin. By the Donpisha CCD camera attached to an Olympus BX-51 optical microscope 180 color images come to be acquired. For evaluation of the systems, transmission times and telediagnosis concordance rates were measured. Image processing ability was tested using two telepathology systems. For the local area test, system I using CORBA had measured image transmission times of 0.1 s, 0.2 s, and 0.4 s at the file sizes of 100 K byte, 900 K byte and 3.6 M byte respectively. Transmission times for system II using Component Object Model (COM) were slightly slower, ranging from 0.02 s to 0.05 s. In the long distance area test, system II transmission times were 0.5 s, 0.8 s, and 2.0 s. The overall concordance rate of telediagnosis for the 180 images was 78.3%. In this study, we compared our systems about image transmission, and processing for the further development of system configurations.

OBJECTIVE:
To explore the treatment conditions of acid decalcified specimens and improve the poor quality of sections and unclear structure of hematoxylin-eosin (HE) staining caused by the change in pH in tooth and hard tissue after acid decalcification.
METHODS:
A total of 20 cases of oral pathological specimens that contain hard tissues were decalcified and treated with routine treatment, concentrated ammonia water immersion treatment, and saturated lithium carbonate solution immersion treatment. The quality and HE staining effects of hard tissue sections treated with different methods were compared.
RESULTS:
Compared with routine treatment, lithium carbonate saturated solution treatment showed complete sections. Hematoxylin is strongly stained, the nucleus is clear, and the cytoplasm is bright.
CONCLUSIONS
Soaking acid decalcified specimens in lithium carbonate saturated solution before embedding in dehydration can neutralize the acidic environment of the tissue. The quality of sections and HE staining effect are improved and are suitable for the pretreatment of acid decalcified tissue samples of oral pathology.

Glassy cell carcinoma (GCC) of the uterine cervix is a rare and highly malignant tumor, accounting for only 1%~2% of all cervical carcinomas. It is typically composed of malignant cells having a moderate amount of cytoplasm with "ground glass" appearance, distinct cell membranes that stain with eosin or periodic acid-Schiff, and large nuclei with prominent nucleoli. Since its original description in 1956 by Glucletmann and Cherry, 200 - 250 cases of GCC of the uterine cervix have been listed in the literature. We report here the clinicopathological study of one case of glassy cell carcinoma with brief review of the literature.

4.Experimental Study on Reviability of Cryopreserved Human Spermatozoa.
Korean Journal of Urology 1988;29(6):961-968
In order to perform standardization in analytic methods of cryopreserved human semen, to investigate the differences of resistance to cryoinjury, to define the stage of critical cryoinjury during cryopreservation and to evaluate the quality change after thawing by time interval, the reviability of 30 normal and 30 abnormal semen were evaluated by the supravital stainings of spermatozoa using acridine orange and eosin yellow and the motility assay simultaneously according to the stages of freezing-thawing and the time interval after thawing. The results were summarized as follows: 1. Vitality was estimated higher than motility at all specimens and the gap between two became greater as motility decreased. 2. Reviability of abnormal semen was estimated lower than that of normal semen(p<0.05). 3. The critical cryoinjury to spermatozoa was noticed at the stage of freezing from 4 degrees C to -10 degrees C (p<0.05). 4. The significant decrease in quality of normal cryopreserved semen was noticed between 30 to 60 min. after thawing (p<0.05). These results suggest that the cryoinjury to human semen is different in nature, therefore it is advisable that the quality of cryopreserved human semen should be evaluated by vitality and motility assay simultaneously. And the resistance of abnormal semen to cryopreservation is so low that it would be difficult to be used clinically with satisfaction. Moreover the laboratory studies should be concentrated on freezing method to achieve better reviability and it is desirable in practice that post-thaw semen should be used within 30 min, after thawing.

We tested a set of conditions for obtaining optimal tissue quality in preparation for histology in samples of mouse brain. C57BL/6J mice were sacrificed and perfused with 4% paraformaldehyde, after which the brains were removed and dehydrated in 30% sucrose solution. The brains were then divided into four groups according to freezing temperature and usage of optimal cutting temperature (OCT) compound. Next, we stained the sectioned brain tissues with Harris hematoxylin and eosin Y and immunohistochemistry was performed for doublecortin. The best quality tissue was obtained at -25℃ and by not embedding with the OCT compound. When frozen at -25℃, the embedded tissue was significantly damaged by crystals, while at -80℃ there were no meaningful differences between qualities of embedded- and non-embedded tissues. Overall, we identified a set of conditions to obtain quality frozen brain sections. Our developed protocol will help resolve matters associated with damage caused to sectioned brain tissue by crystal formation during freezing.

6.A Study on the Clinical and Histopathologic Classification of Leprosy.
Korean Journal of Dermatology 1980;18(6):523-528
For comparison of clinical classification of leprosy to histopathologic classification, a detailed histopathologic study, using hematoxylin and eosin stain and Ziehl-Neelsen stain, was done on 72 fresh uncomplicated cases of leprosy. The clinical classification was done using the criteria of Ridley and Jopling (1966), and the microscopic features were classified according to Ridley's(1974) definition. Clinical classification revealed that 8 of total 72 patients had tuberculoid(TT), 9 had borderline tuberculoid (BT), 5 had borderline(BB), 10 had borderline lepromatous.(BL), and 31 had lepromatous leprosy(LL). Nine patients were claasified as indeterminate(I) group. Histopathologic classification showed that 3 cases presented tuberculoid(TT), 10 presented borderline tuberculoid(BT), 4 presented borderline(BB), 9 presented borderline lepromatous(BL), 20 presented subpolar leprornatous(LLs), and 10 presented polar lepromatous(LLp) histopathologic characteristics, Sixteen cases were classified as indeterminate(I) leprosy by histopathologic findings. On comparison of clinical classification to histopathologic classification, the two were in consonance with each other in 50 cases(69.4%) and the disparity between them was noticed in 22 cases(30.6%). Among the 22 cases which showed disparity, there was a shift of one step either towards the tuberculoid or lepromatous end of the spectrum in 15 cases, and ihe remaining 7 cases were classified as indeterminate group beaause of nonspecific histopathologic changes.

STATEMENT OF PROBLEM: Reducing treatment time in implant dentistry is a matter of main concern. There are so many factors affecting the success rate of immediate or early loaded implant for the initial bone response. The especially microscopic properties of implant surfaces play a major role in the osseous healing of dental implant. PURPOSE: The aims of this study were to perform a histologic and histomorphometric comparison of the healing characteristics anodically roughened surface, HA coated surface and RBM surface implant, and to compare of ISQ values measured by Osstell(TM) for resonance frequency analysis in dogs mandible during 2 weeks. MATERIAL AND METHOD: Bone blocks from 2 dogs were caught after covered healing for 0 day(2h); Group I, 1 week; Group II and 2 weeks; Group III. One longitudinal section was obtained for each implant and stained with hematoxylin and eosin. Histomorphometric analysis was done with Kappa Imagebase system to calculate bone-to-implant contact and bone volumes inside the threads. ISQ values were measured in every time of surgery schedule. CONCLUSION: The experiment revealed that : 1. The percentages of bone-to-implant contact on the fixture in each group were not significantly different(P > 0.05). 2. The percentages of bone area inside the threads on the fixture in each group were not significantly different(P > 0.05). 3. The ISQ level showed clinical stability of each fixture during 2 weeks(all ISQ level >_71).

PURPOSE: We report a rare case of solitary neurofibroma on the eyelid margin without neurofibromatosis. CASE SUMMARY: A 46-year-old male presented with a well-define small nodular lesion on the right upper eyelid margin that had not changed for 10 years. Surgical excision and biopsy were performed. Histological examination showed spindle-shaped cells in the fibrous stroma on hematoxylin & eosin staining, and immunohistochemical staining revealed S-100 protein-positive cells. Dermatologic, neurologic, and genetic evaluations showed no evidence of systemic neurofibromatosis. Six months after operation, there was no evidence of local recurrence. CONCLUSIONS: To the best of our knowledge, this is the first case of solitary neurofibroma involving the eyelid margin without neurofibromatosis in Korea. Neurofibroma should be considered in a differential diagnosis of eyelid mass and can be successfully managed with surgical excision.

PURPOSE: This study was performed to evaluate chromatin condensation of morphologically mature sperm using a modified aniline blue-eosin (AB-E) staining method in azoospermia. MATERIALS AND METHODS: Chromatin condensation was analyzed using an AB-E staining method in 61 cases (50 patients) of TESE or testicular biopsy with the patient's own sperm. Obstructive azoospermia (OA) was present in 48 cases in 39 patients and non-obstructive azoospermia (NOA) was present in 13 cases in 11 patients, respectively. Immature sperm heads were stained dark blue, whereas mature sperm were stained red-pink by the eosin. The percentage of sperm chromatin condensation was calculated from the ratio of the number of red-pink sperm to the total number of sperm analyzed. RESULTS: The percentage of chromatin maturity was 37.7% vs. 30.3% in OA and NOA, respectively, of the total sperm cell count. The maturity of fresh testicular sperm was 38.3% and 36.3% in OA and NOA, respectively. Also, the maturity of thawed testicular sperm was 34.5% and 10.3% (p<0.05) in OA and NOA, respectively. The maturity of fresh and thawed testicular sperm was 36.3% and 10.3% (p<0.05), respectively, in NOA. These results suggest that chromatin condensation is less stable in sperm of NOA and freezing and thawing procedures may impair sperm chromatin condensation. CONCLUSIONS: In our results, the aniline blue-eosin staining method improved the visualization of excessive histones in sperm and the diagnosis of sperm immaturity in morphologically normal testicular sperm. We found that AB-E staining method can be an effective method for analyzing testicular sperm chromatin condensation in azoospermia.
