BACKGROUND AND OBJECTIVES: There are caloric test, SCEP, DP in Step velocity and VOR asymmetry in SHA test as parameters for evaluation in unilateral peripheral vestibulopathy in parameter of vestibular function test. The aim of this study is to assess the correlation between these parameters and intensity of spontaneous nystagmus in vestibular neuritis. MATERIALS AND METHOD: We evaluated 75 patients who were diagnosed as vestibular neuritis with 3 degree spontaneous nystagmus at vestibular function test lab from January 2000 to July 2005 in Dankook university hospital. The correlations between direction and intensity of spontaneous nystagmus and monothermal caloric test, SCEP and DP in step velocity, VOR asymmetry (0.01, 0.04, 0.16 Hz) in SHA test were analysed. And correlations according to sex, age were also analysed. RESULTS: The correlation coefficient between intensity of spontaneous nystagmus and monothermal caloric test was 0.60. The correlation coefficient between intensity of spontaneous nystagmus and SCEP was 0.35. The correlation coefficient between intensity of spontaneous nystagmus and Tc DP was 0.36 and it showed no significant correlation. The correlation coefficient between intensity of spontaneous nystagmus and VOR asymmetry (0.01, 0.04, 0.16) was 0.57, 0.46, 0.51, respectively and there was higher correlation in man, age under 60. CONCLUSION: Intensity of spontaneous nystagmus showed close relations to monothermal caloric test, VOR asymmetry of SHA, Tc DP, SCEP DP in sequence. In addition, young male patients tends to be closely related to intensity of spontaneous nystagmus.

A study of effect of local hypothermia upon the paravertebral muscles which also become sensitized during spinal cord cooling was performed using cats. With a cuff, a cooler, to which was attached tubes connected to a refrigerator, the experimental technique was deviced to cool the paravertebral muscles locally at cervical and lumbar level. Cold, liquid saline at a temperature of 2.8+/-0.6 degrees C was circulated in closed system through the tube into the cuff which was snugly rested on the surface of paravertebral muscles as a heat exchanger. The temperature was measured at intervals of ten minutes with thermocouples before and during cooling for thirty minutes. In the muscle surface underneath the cuff, the mean precooling temperature of 30.1 degrees C in the normal muscle was lowered to 15.4 degrees C at the end of the first 10 minutes of cooling. After this initial rapid drop in temperature, there was a further gradual decrease of temperature to 13.6 degrees C at the end of 20 minutes of cooling. In the muscle 1cm beneath the cuff, the mean precooling temperature of 31.4 degrees C in the normal muscle was lowered to 17.3 degrees C at the end of first 10 minutes of cooling. After this initial rapid drop in temperature, there was a further gradual decrease of temperature to 16.2 degrees C at the end of 20 minutes of cooling. For comparison, the temperature in the clipped muscle and nonclipped muscle were also measured. The temperature in the clipped muscle surface was lower than that of non-clipped. Topical ice application resulted in rapid drop of temperature from 31.2 degrees C to 13.9 degrees C in skin, 32.3 degrees C to 13.1 degrees C in subcutaneous layer and 32.5 degrees C to 13.9 degrees C in muscle, simultaneously. Another aspect of this experiment was an evaluation of the protective effect of local hypothermia with respect to muscle injury associated with clipping, of muscles. The injured(clipped) muscles with or without local hypothermia was biopsied and stained with Hematoxylin Eosin and Hematoxylin Basic Funchsin Picric acid and sectioned specimens were observed under the light microscope. The clipped muscle examined thirty minutes after release of clipping showed 20~30% of red stain in HBFP stain. The normal muscle showed less than 5% of red stain in the field. In intermittent hypothermia, 2 minute cooling group showed 20% of red stain in the field. The clipped muscle with local hypothermia showed less red stain than that of non-hypothermia. The results of this study confirmed the belief that the cold liquid and ice of physiologic saline can be used in clinical neurosurgery for extravascular local cooling of scalp and paravertebral muscles and for irrigating or perfusing operative field.

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.

Generalized pustular skin eruptions as a form of drug eruption is a rare entity. Recently this unique pustular dermatosis has been termed as acute generalized exanthematous pustulosis. We report on a 19-year-old man with acute generalized exanthematous pustulosis probably induced by ampicillin. The patient presented with erythematous and pinhead-sized subcorneal pustules after taking ampicillin for abdomimal pain. The patient complained of high fever and malaise. On further review of his history, generalized skin eruptions had been noted on at least three other occasions. Each episode occured following oral administration of antibiotics. A histological examination of a skin biposy specimen showed a subcorneal pustules with a few neutrophils, dermal edema and necrotic keratinocytes. After discontinuation of ampicillin, the eruption cleared within 4 days.

OBJECTIVES: The post-tonsillectomy pain and post-tonsillectomy hemorrhage are the two main problems after tonsillectomy. The aim of this study was to investigate the beneficial effects of water soluble ethanol extract propolis on post-tonsillectomy patient. METHODS: One hundred and thirty patients who underwent tonsillectomy or adenotonsillectomy were randomly divided into the control and propolis groups, each including 65 patients. The propolis group was applied with propolis orally immediately after surgery and by gargle. The pain scores were assessed on post-tonsillectomy 0, 1st, 2nd, 3rd, and 7th–10th day using a visual analogue scale score. Postoperative wound healing was evaluated by scoring pinkish membrane of tonsillar fossae on postoperative days 3 and 7–10. The incidence of post-tonsillectomy bleeding was examined in each group. RESULTS: Post-tonsillectomy pain was significantly less in propolis group compared to control group on postoperative days 3 and 7–10. Post-tonsillectomy hemorrhage was significantly less in the propolis group compared to the control group (P < 0.05). The wound healing was significantly better in the propolis group compared to the control group on postoperative day 7–10 (P=0.002). CONCLUSION: Applying the propolis to post-tonsillectomy wound showed beneficial effect of reducing postoperative pain, preventing hemorrhage, and accelerating of wound healing of tonsillar fossae.

Using barrier membrane, guided bone regeneration(GBR) and guided tissue regeneration(GTR) of periodontal tissue are now widely studied and good results were reported. In bone regeneration, not all cases gained good results and in some cases using GTR, bone were less regenerated than that of control. The purpose of this study is to search for the method to improve the success rate of GBR and GTR by examination of the cause of the failure. For these study, rats and beagle dogs were used. In rat study, 5mm diameter round hole was made on parietal bone of the rat and 10mm diameter of bioresorbable membrane was placed on the bone defects and sutured. In 1, 2, 4 weeks later, the rats were sacrificed and Masson-Trichrome staining was done and inspected under light microscope for guided bone regeneration. In dog study, 3x4mm2 Grade III furcation defect was made at the 3rd and 4th premolar on mandible of 6 beagle dogs. The defects were covered by bioresorbable membrane extending 2-3mm from the defect margin. The membrane was sutured and buccal flap was covered the defect perfectly. In 2, 4, 8 weeks later, the animals were sacrificed and undecalcified specimens were made and stained by multiple staining method. In rats, there was much amount of new bone formation at 2 weeks, and in 4 weeks specimen, bony defect was perfectly closed and plenty amount of new bone marrow was developed. In some cases, there were failures of guided bone regeneration. In beagle dogs, guided tissue regeneration was incomplete when the defect was collapsed by the membrane itself and when the rate of resorption was so rapid than expected. The cause of the failure in GBR and GTR procedure is that 1) the membrane was not tightly seal the bony defects. If the sealing was not perfect, fibrous connective tissue infiltrate into the defect and inhibit the new bone formation and regeneration. 2) the membrane was too tightly attached to the tissue and then there was no space to be regenerated. In conclusion, the requirements of the membrane for periodontal tissue and bone regeneration are the biocompatibility, degree of sealingness, malleability, space making and manipulation. In this animal study, space making for new bone and periodontal ligament, and sealing the space might be the most important point for successful accomplishment of GBR and GTR.
