BACKGROUND: The effectiveness for vagal stimulation by ice water aplication to face during metronome-controlled respiration of 15 breaths/minute was examed. The importance of basal vagal tone and sympathovagal interaction in the individual variability of responsiveness to the vagal stimulation was investigated. METHOD: Fifty three 12~13 year old healthy volunteers were included. Vagal tone and sympathovagal interaction before and after application of ice water to the face were assessed by power spectral analysis of RR interval(heart rate) variability. RESULT: Basal heart rate, high frequency power, and low to high frequency power ratio were 81+/-13(58~110 beats/min), 791+/-1061(56~4161 msec2) and 1.08+/-1.22(0.04~4.85) during controlled respiration. After ice water application twenty three children developed 5 more nodal escape beats due to severe bradycardia. Minimum heart rate, high frequency power and low to high power ratio changed to 42+/-12(19~72/min), 1890+/-1882(221~7258msec2) and 0.64+/-0.43(0.12~1.46). The increased ratio of high frequency power, maximum heart rate decrement and its percent after stimulation were 5.44+/-5.62(0.63~24.26), 39+/-14(10~81/min) and 47+/-15(16~81%) respectively. The increased ratio of high frequency power was correlated with basal logarithmic high frequency power(r=-0.60, p=0.0004). Maximum heart rate decrement was correlated with basal logarithmic high frequency power(r=-0.41, p=0.0018) and low to high frequency power ratio(r=0.27, p=0.04). CONCLUSION: Application of ice water to the face during controlled respiration produces powerful vagal stimulation and bradycardia, however, there is a wide individual variability of responsiveness to it. The absolute basal vagal tone contribute to this individual variability.

PURPOSE: The aim of this study was to determine the relative radiopacities of cavity lining materials (Resin-modified Glass Ionomer cement, Compomer and Flowable resin) for posterior composite resin restoration. MATERIAL AND METHODS: Resin-modified glass ionomer cement (Fuji II LC, Vitrebond(TM)), Compomers (Dyract , Compoglass, F2000, Dyract(R) flow Compoglass Flow) and Flowable resins (Tetric(R) flow, Aeliteflo(TM) Revolution(TM)) were used. Five specimens of 5mm in diameter and 2mm thick were fabricated with each material. Human molars were horizontally sectioned 2mm thick to include both enamel and dentin. The radiopacities of enamel, dentin, cavity lining materials, aluminum step wedge were obtainded from conventional radiograph and NIH image program. RESULTS: All the tested lining materials showed levels of radiopacity the same as or greater than that of dentin. All compomer tested (Dyract(R), Compoglass, F2000, Dyract(R) flow, Compoglass Flow) and Vitrebond(TM), Tetric(R) flow were more radiopaque than enamel. The radiopacities of Fuji II LC and Revolution(TM) were between enamel and dentin and resin-modified glass ionomer cement, Compomer and Tetric(R) flow were greater than those of Revolution(TM), Aeliteflo(TM) or dentin. The level of radiopacity of the tested materials was variable; those with low radiopacity should be avoided in class II restorations, where a clear determination of recurrent caries by the examining clinician could be compromised. CONCLUSON: Clinician should be able to distinguish these cavity lining materials radiographically from recurrent decay, voids, gaps, or other defects that lead to clinical failure. Utilization of materials ranked more radiopaque than enamel would enable clinicians to distinguish the lining material from tooth structure.

PURPOSE: During the night time decision making on patients suspicious of appendicitis is often difficult because diagnosis and timing for operation are frequently delayed. Therefore, we analyzed above cases and solution is suggested. METHODS: This retrospective study included 360 patients who underwent laparotomies for suspected appendicitis at Hanil Hospital during one year, from March 1998 to Feb. 1999. They were divided into two groups according to presenting time to physician (Day time: 6 a.m. to 6 p.m., Night time: 6 p.m. to 6 a.m.). Sex & age distribution, time of presentation to physician, duration of symptoms, symptoms & physical findings, white blood cell counts, interval from presentation to operation, hospital stay, and pathologic diagnosis were compared. RESULTS: There were no significant differences in sex & age distribution, duration of symptoms, symptoms & physical findings, white blood cell counts, pathologic diagnosis between the two groups. However, during the night time, the interval from presentation to operation was longer than that of the day time (9.15 hours versus 4.83 hours, p<0.001), the rate of delayed appendectomy during the night was 58.0%, the rate of negative laparotomy increased when appendectomy was delayed for more than 12 hours compared with less than 12 hours (28.1% vs 11.7%, p<0.01), and in the cases with perforated appendicitis, delayed appendectomy for more than 12 hours had longer hospital stay compared with less than 12 hours (12 days vs 9.44 days, p<0.01). Factors causing delayed appendectomy were related to the physician (42.5%), lack of anesthetic & nursing supports (19.5%), failure to structure the operation team (20.7%), and patient itself (17.3%). When white blood cell counts were rechecked in the next morning, levels above 10,000 cells/mm3 were highly associated with appendicitis in contrast to that below 10,000 cells/mm3 (91.7% vs 43.5%, p<0.002).

The authors observed a case of malignant mixed germ cell-sex cord stromal tumor occuring in a 43-year-old woman. A laparotomy perfomed on August 3, 1994, revealed a large roughly round, partially ruptured tumor in the right ovary. The tumor mass weighed 330 gm and its dimensions were 11X9X8 cm. Tumors composed of germ cells and sex cord stroma intimately associated togther are very rare. Interest in these gonadal tumors that are distinct from gonadoblastoma has mouted in recent years. The tumor behaves in a benign clinical course and occurs predominantly in female infats and children with normal 46.XX karyoytype. This tumor differs from gonadobalstoma in its histologic pattern, absence of regresive changes, lack of association with other neoplastic germ cell elements, and occurrence in normal gonads.Histologically, the mass was characterized by an intimate admixutr of germ cells and sex cord stromal cells. The lesion had many predominant setoli tuble formations and lipid cell changes. But it lacked Call-Exner like bodies, calcification and byalinization that charaterize gonadoblastomas. Typical areas of dysgemonoma and endodermal sinus tumor were also present the patient subsequelty received chemotherapy(blemycin,etoposied, and cisplatin administered in 5cycles), The patient was symptom free two yares after surgery and chemotherapy.

Atopic dermatitis is a common chronic inflammatory skin disease, associated with marked inflammatory cells (of mast cells and eosinophils) and severe itching, which leads to clinical problems in the pediatric population. This study was designed to investigate the inhibitory effects of luteolin liposome solution, that is entrapped the hydrophobic luteolin (one of the flavonoids) into ethosome to improve its stability, by using hapten-induced atopic dermatitis animal model (NC/Nga mice).The luteolin liposome treated mice showed anti-inflammatory effect as evidenced by the lowering of erythema and edema in clinical observation, reduction of inflammatory cell infiltration and epidermal thickness in histopathological examination, when compared with TNCB induced controls. Luteolin liposome solution also reduced the serum IgE level which played important roles in the atopic dermatitis model. These results suggest that luteolin liposome solution has some merit in this formulation showing inhibitory effects for the atopic dermatitis.

Sixteen patients with prostatodynia underwent clinical studies including urodynamic study, MMPI, and endoscopy. As a control group, another 19 patients with nonbacterial prostatitis and 16 normal man of 20-40 years of age also underwent urodynamic study. The most characteristic urodynamic findings in patients with prostatodynia was a significant increase in maximum urethral closing pressure as compared to control group (mean, 140.9 : 92.1 : 84.1 cmH20). In prostatodynia group, peak urinary flow rate was also significantly decreased as compared to the control group (mean, 12.0: 17.8 : 23.9cc / sec). 11 of 16 patients with prostatodynia was found to have functional outlet obstruction, probably at sympathetically innervated urethral sphincter. And they were treated with minipress and diazepam, of whom 7 showed significant improvement both symptomatically and urodynamically. On MMPI 7patients with prostatodynia showed significant underlying psychiatric disorders, and were treated by psychiatric treatment, of whom 4 showed significant clinical improvement. 2 patients with prostatodynia showed vermontanal pseudopolyp suggestive of prostatitis, were treated with long term TMF-SMX administration, and showed significant improvement. It is suggested that prostatodynia may develop from urethral sphincter overactivity and underlying psychiatric disorders, and that at least some cases with prostatodynia are in fact prostatitis. Uroflowmetry, urethral pressure profile, MMPI study and repeated EPS study may be of help in deciding the treatment plan of prostatodynia.
