To assess the immunological function of toluene exposed group, the proportions of T lymphocyte, B lymphocyte, CD 4 cell, CD 8 cell, the ratio of CD4 to CD8 (CD4/CD8) in peripheral blood were measured on twenty-one toluene exposed workers and twelve healthy workers who did not have previous history of toluene exposure. In addition, to evaluate the present status of toluene exposure, urinary hippuric acid concenturations were measured in exposed group. The mean concenturation of urinary hippuric acid was 2.84 g/creatinine g in exposed group. The proportions of T lymphocyte, B lymphocyte, CD8 cell and CD4/CD8 of exposed group were slightly lower than non-exposed group except the proportion of CD4 cell which was similar in both groups. But these differences were not statistically different in both groups. The proportions of T lymphocyte and CD4 cell were significantly correlated with the length of duration in exposed group (P<0.05)

The study conducted from May to September in 1994 to investigate applicability of the Hearing Handicap Inventory for the Elderly-Screening version(HHIE-S) in parallel with the puretone audiometer to the initial screening test of noise-induced hearing loss(NIHL) in some noise-exposed workers. Subjects were selected by systemic sampling that took every fifth person from 6,700 workers taking the annual occupational health examination by the department of Health Maintenance of Dongsan Hospital Keimyung University in Taegu. The authors administered the pure-tone audiometric test and self-reported questionnaire of HHIE-S including items of sociodemographic and job-related variables concurrently. The final subjects analysed were 1,019(488 males and 531 females) excluding fourteen persons who had many missing values in their questionnaires. The reliability coefficients of HHIE-S scale by Cronbach's alpha were 0.84. In the univariate analysis of hearing handicap measured by the HHIE-S, work duration, military service and the hearing threshold loss at 1kHz and 4kHz was the only selected variable explaining the hearing handicap in males and hearing threshold loss at 1kHz and 4kHz, age, and work duration were selected in females. In ROC curves for HHIE-S scores against NIHL as gold standard which was defined by the follow-up audiogram as more than 30dB of the average of 0.5/1/2kHz and 50dB at 4kHz, the optimal cutoff for the parallel HHIE-S appeared to be 8. The results suggest that HHIE-S appeared to have some reliability and validity in this data and might be used in screening NIHL in parallel with pure-tone audiometer in noise-exposed workers.

OBJECTIVE: Nitric oxide (NO) produced in ovary may contribute to follicle maturation, ovulation, oocyte maturation and luteinization. In this study, the effect of nitric oxide on the spontaneous maturation of mouse oocyte was observed. Method: The index of oocyte maturation was checked by the germinal vesicle breakdown (GVBD) and appearance of polar body (PB) under microscope in the denuded oocytes and oocyte-cumulus complexes (OCCs) from mouse ovarian follicles after 24 hours pregnant-mare serum gonadotropin treatment. RESULTS: The GVBD appeared 50 %, 1 hour and 80 %, 2 hrs after changes of oocytes from dibutyryl cAMP (dbcAMP, 0.5 mM) contained media into dbcAMP-free media. dbcAMP (0.5 mM) completely blocked the GVBD until 24 hrs but dbcGMP (5 mM) delayed the GVBD by 1 hr. Sodium nitroprusside, the NO generator, inhibited the GVBD dose-dependently at 2 hr incubation in denuded and OCCs. The appearance of GVBD was not different between control and dbcGMP or SNP in denuded oocytes and OCCs at 24 hrs incubation. The guanylate cyclase activity in denuded oocyte cytosol was not detected whereas the guanylate cyclase activity in OCCs cytosol was 1.3 nmole/min/mg protein which was increased about 3 times by SNP (100 micrometer). CONCLUSION: These results suggest that the NO in ovary may delay the spontaneous oocyte maturation in early stage by acting on the maturation signaling protein as well as guanylate cyclase.

Background: Univent(R) tube was designed to overcome the disadvantages of double lumen endotracheal tube for one lung anesthesia. But overinflation of the blocker cuff of an endobronchial tube can cause pressure damage to the bronchus. The purpose of this study was to evaluate whether the blocker cuff pressure and the duration of ballooning using the Univent(R) tube is correlated with the degree of bronchial mucosal damage (BMD). Methods: A total of 13 men and 7 women intubated with the Univent(R) tube were enrolled for the study. The BMD were evaluated by direct visualization using fiberoptic bronchoscopy prior to intubation and following extubation and the degree of the BMD were scored from 0 to 4 as follows; 0: normal, 1: erythema, 2: swelling, 3: hemorrhage, 4: mucosal wall tearing. Results: No change in bronchial mucosa (score 0) were observed in 11 patients (55%), erythema (score 1) in 5 patients (25%), swelling (score 2) in 3 patients (15%), hemorrhage (score 3) in 1 patient (5%) and mucosal wall tearing (score 4) is none in 20 patients. The bronchial blocker cuff pressure required to "just sealing" the bronchus was 178.1+/-37.4 mmHg with corresponding cuff volume of 6.7+/-1.0 cc. The duration of ballooning was 115.5+/-26.4 min. The correlation coefficient between the blocker cuff pressure and duration of ballooning to the degree of bronchial mucosal damage were 0.125 and 0.137, respectively, which was not statistically significant. Conclusions: The bronchial blocker of Univent(R) tube doesn't cause any severe BMD and the degree of BMD are correlated with neither the bronchial blocker cuff pressure nor duration of ballooning of Univent(R) tube.

The isomorphic response of Koebner is a well-known phenomenon commonly associated with psoriafsis, but it has been also descrilbed in conjunction with a host of other disordered. We described five cases of erythema multiforme showing lesions of easily recognizsble Koebnei phenomena. Traumas to the skin do not cause erythema multiforme, however when a patient is in an active stage of the disease, physieal factor such as traumas occuring in normsl daly-life may contribute to the distribution of skin lesions as have been seen in our patients ; clinicians should aware of this point for better understanding of clinical features in erythema multiforme.
