Canalith repositioning maneuver is effective to treat benign paroxysmal positional vertigo(BPPV). This case showed complicated form of the BPPV such as changes of canalolithiasis to cupulolithiasis, involvement of one canal to two canals and from unilateral to bilateral involvement during the reposition maneuver. This patient was diagnosed as left lateral canalolithiasis at first. After left barbecue maneuver, the type was changed to the right posterior cupulolithiasis. Semont maneuver was performed and then the type of BPPV was changed to combined type with right posterior canalolithiasis and left lateral canalolithiasis. We performed left barbecue maneuver and right Epley maneuver. Then the type of BPPV was changed to left lateral cupulolithiasis. After Brandt-Daroff maneuver and left barbecue maneuver, nystagmus and dizziness disappeared finally.

The methods of reconstruction for chronic Iigamentous instability of the knee have changed much since the concept of rotary instability was introduced by Slocum and Larson in 1968. The first step to successful management of these probrams is the accurate dlagnosis of the type or types of the instability that exist. Appropriate operative procedures should then be selected according to the type and degree of the instability as well as the age, general conditlon and the function demand of the patient. The stability can be restored passively by a near anatomical. repair of the injured ligaments, and can be reinforced actively by a proper muscle or tendon transplantation, such as the five-one procedure for anteromedial rotary instability. Nineteen knees of active, well motivated patients were operated on for chronic knee instabilities according to these new concepts. Although the follow-up period was relatively short, the results of the procedures was generally satisfactory.

OBJECTIVE: To show the value of rotating chair test (ROT) as an adjunct to the conventional electronystagmography (ENG) examination including caloric test for the diagnosis of vestibular lesions. BACKGROUND: Since caloric stimulatim is regarded as a very low frequency (0. 003Hz) test, it is desirable to test the function of horizontal semicircula canals by stimulating with faster frequencies. Baloh et al. (1984a) described that lesions ofdifferentiated by ROT. Leigh and Zee(1991) told that ROT can give more accurate and reproducible results than do caloric tests. METHOD: 30 patients who suffered from vertigo with either peripheral or central pathology were given computerized ENG and ROT. We discuss the representative examples of our initial experience with ROT. RESULTS: 1.In eight patients with known peripheral pathology, low-frequency phase deficits, asymmetry toward the lesim side and VOR suppression by gazefixation were seen during ROT. With bilateral peripheral vetibular disease, the ROT could identify remaining vestibular function at higher frequencies. 2. Seven patients with lesions of central vestibular structure showed abnormalities of saccades and pursuit during ENG and failure of VOR suppression by gaze fixation during ROT. 3. Out of 15 patients whose lesions could not be localized distinctly after caloric test, four patients were suggested to have central pathology. CONCLUSION: ROT can be a useful method to study the vestibular abnonnahties and an adjunct to the conventional ENG test.

It has been reported that Magnoliae cortex extract has antibacterial and antimicrobial activity against pathogenic microbes and Zea Mays L. extract is effective for improving gingival tissue health. The purpose of this study was to examine the anti-inflammatory and antimicrobial effects of Zea Mays L. and Magnoliae cortex extract mixtures through experimental periodontitis induced beagle dog model. Nine beagle dogs with experimentally induced periodontitis were selected. Baseline clinical indices which includes plaque index, gingival index, probing pocket depth, clinical attachment level, gingival fluid flow rate were recorded and microbial assays were done. Magnoliae cortex and Zea Mays L., mixed at 2:1 ratio in 105mg capsular dosage, were taken by 3 capsule (Group I) or 6 capsule dosages (Group II) three times a day. After 4,8,12 weeks, clinical indices were recorded. All data of clinical indices were compared through one-way ANOVA with 95% confidence level. Clinical indices of group I and II showed significantly better results than those of control group. There were no significant differences between group I and II. In conclusion, it was confirmed that mixture of Magnoliae cortex and Zea Mays L. (mix ratio 2:1) possessed clinical improving effects to periodontitis.

Amyloidosis is a disease complex associated with deposition of inscluble fibrillar protein in vnrious tissues of the body. Since the term, amyloidosis was first introduced by Virchow in 1853, there have been many reports in English literature, but only a few cases of iriinary systemic amyloidosis have been reported in Korea. A 56-year-old male was seven for facial purpuras, macroglossia, myilgia and arthralgia for 5 years. Histologically, the skin biopsy specimen showed amorphous, faintly eosinophilic and fissured masses of amyloid in the upper dermis that demonstrated characteristic green brefringence on Congo red staining when viewed under polarized light. Electron microscopic exanintion showed that nonbranching and nonanastomosing straigh. fibrils are irregularly arranged arouned tlie collagen fibers. Therefore, he was diagncsed with primary systemic amyloidsis by the characteristic clinical, histopathologic and ultrastructural findings.

Nevus flammeus is a benign but cosmetically devascating congenital inalformation involving mature capillaries. The copper vapor laser is a therapeutic device which had been newly applied to this. Yellow copper vapor light is absorbed by the intraluminal oxyhemoglobulin mo ecules, leading to the destruction of blood vessels. This study was undertaken to evaluate the histobigic findings in a patient with nevus flammeus according to the sequential time after copper vapor laser therapy. The results were as followed, One hour after treatment, nonspecific damages to the epidermis and upper part of the dermis were observed. The specific damage to the vessels which showed thrombi formations and partial disruption of the vessel walls was prominent. One cay after treatment, degeneration of the epidermis and sepaiation of the dermoepidermal junction were apparent. Three days after treatment, extravasations of a small amount of erythrocytes and inflanimatory cell infiltrations were present, especially around the vessels. Seven days after treatment, the capillaries showed a deposition of fiorinoid material around themselves. Partial disappearance of the vessel walls was seen. There was hisi ologic evidence of the replacement of abnormal ectatic vessels by normal appearing vessels with small uminal diameters, surrounded by endothelial cells.

BACKGROUND: Preservation of antigen determinants while retaining morphological detail is prerequisite for high quality immunohistochemistry. Conventional formalin fixation and paraffin embedding procedures are useful in preserving tissue architecture and cytologic detail. However, they destroy the antigenicity of many proteins is tissue samples. On the other hand, fresh frozen section preserve the antigenicity of most proteins, but vield poor morphological preservation. OBJECTIVE: The purpose of this study is to evaluate the AMeX method as to the ability to preserve both antigenicity and morphologic details of the skin basement membrane zone so that precise localization of antigens can be attained in immunohistochemistry. METHODS: Tissues were fixed in acetone at -20degrees C over night, then cleared in methyl benzoate and xylene, consecutively, and embedded in ordinary paraffin at 58-60degrees C. Sections made from this paraffinembedded tissue were stained with hematoxylin and eosin for a morphologic study and immunolabelled with antibodies against major basement membrane antigens to evaluate antigenic preservation. The staining intensity and preservation of the morphology by the AMeX method were compared with conventional formalin processed tissues and frozen tissues. RESULTS: Morphological preservation of the AMeX method-processed sections was good throughout the epidermis, basement membrane, and dermis, and as good as that of routinely formalin-fixed paraffin-embedded sections. Frozen sections usually revealed revealed various degrees of damage by ice crystal formation throughout the epidermis to the dermis. The AMeX method-processed sections showed better or same antigenic preservation comparing the frozen sections when the sections were immunolabelled with specific monoclonal antibodies. But, when the sections were immunolabelled with patient's sera, the AMex method showed less antigenic preservation than the frozed sections. The anti-type IV collagen monoclonal antibody exhibited immunoreactivity only conventional formalin-fixed paraffin-embedded skin sections, but the intensity of the staining was weaker than the AMeX processed sections and the frozen sections. CONCLUSION: The AMeX method can be utilized for the demonstration of skin basement membrane antigens and is superior to the fresh-frozen method in that the histologic figures are more distinct and antigencity can be preserved for a long time.
