OBJECTIVE: To explore the effects of different recording electrodes on motor nerve conduction latencies. METHOD: Median motor conduction study was performed in 10 healthy subjects. Motor conduction latency was determined by placing different recording electrodes (surface disc, monopolar needle and concentric needle) at the motor point of the left abductor pollicis brevis muscle, and reference electrodes on the proximal interphalangeal joint of the thumb. Motor nerve conduction recording was performed by using a surface disc, monopolar needle, and concentric needle. For the intramuscular recordings, needles were inserted both superficially and deep. The stimulus electrodes were secured 8 cm proximal to the recording electrodes, and the same intensity was applied throughout the tests. RESULTS: Deep intramuscular monopolar and concentric needle electrodes recorded the shorter latencies, 3.0+/-0.4 ms and 3.0+/-0.3 ms, respectively. Superficial concentric needle electrode recorded the longest latency of 3.4+/-0.3 ms. Motor nerve conduction latencies using a surface disc and superficial monopolar electrode were 3.2+/-0.3 ms and 3.2+/-0.3 ms, respectively. CONCLUSION: We conclude that the distal motor nerve conduction latency is variable depending on the type of recording electrodes.

PURPOSE: Dopamine plays a critical role in promoting sexual drive and penile erection through dopamine receptors. This study was performed to investigate whether the cavernousal nerve controls the expression of peripheral dopamine D1 receptors in rat penile tissues after cavernousal nerve injury. MATERIALS AND METHODS: Male rats (n=20) were divided into two groups: a control group consisting of sham-operated rats (n=10) and an experimental group consisting of rats that underwent incision of the bilateral cavernous nerve (n=10). Three months later, the intracavernous pressure response was monitored using an intracavernous papaverine injection of 300 microgram. The expression of dopamine D1 receptor mRNA were studied using an RT-PCR method, and dopamine D1 receptor protein expression by Western blot analysis and immuno-histochemical staining in each group. The expressed band density of the RT-PCR and Western blot were measured by a densitometer. RESULTS: Erectile functions, as studied by intracavernosal papaverine injection at three months, were similar in both groups. The dopamine D1 receptor mRNA and protein expressions were significantly lower in the neurotomy group. The immuno-histochemical staining also showed a reduction in the dopamine D1 receptor expression in the neurotomy group compared with the control group. CONCLUSIONS: Our results show that dopamine D1 receptors in penile tissues were down-regulated following cavernousal nerve injury. These findings suggest that cavernousal nerve injury affects directly the reduction of dopamine D1 receptor expression, and that the action of dopamine on the cavernousal dopamine receptor will be affected in cavernousal nerve injured rats.

INTRODUCTION: In traditional society, the roles of housewives were to do housework, to look after her children and to give her family emotional stability. With rapid social and economic change, the traditional sense of value changes and the concepts of sexual roles, too. However, they are in a transition period yet. These discord and tension followed by role change appeared as the form of psychological instability or social pathological problem in modern family. Thus, this study aimed to avaluate the effect of employment on depression of housewives who play importent roles in family and their commumity. METHODS: From May to July 1996, the questonnaires were distributed to 179 housewives who have university education background(including community college), and have one or more children and live in Bundang-Ku of Sungnam city, making a distinction between working housewives and nonworking housewives. Regarding the subjects of this study, the non-working housewives are restricted to full-time housewives who have no job, and working housewives who have full-time job. As tools of measurement, we used BDI questionnaires consisted of 15 items in Korean. We performed statistical analysis among the data by means of SPSS/PC+. We analyzed statistical data for significance using one-way ANOVA and analyzed categorical data for significance using S-test. RESULTS: The average score on BDI for working housewives was 12.22(standard deviation 7.42) and this is rather higher than that of non-working housewives(10.80, standard deviation : 7.42). But the number of children increased, the BDI score were higher significantly in both groups. And the BDI score was high in working Housewives groups whose husbands had professional job or dommerce job, whose family system is a multi-generation family, and who feel a lot of fatigue after work. In case of non-working housewives, the BDI score was high with age(especially between 50-59), duration of marriage, lower income and Duvalls family life cycle 6, 7. CONCLUSIONS: There is no difference in depression tendency between working housewives and nonworking housewives. But in case of working housewives, some factors have influence on their depression tendency, the number of children, husbands job, family type, degree of fatigue after work. And in case of non-working housewives, the factors are the number of children, age, duration of marriage, income, family life cycle.

OBJECTIVE: To compare abductor digiti minimi (ADM) recording with first dorsal interosseous (FDI) recording for the localization of ulnar neuropathy at the elbow. METHOD: The subjects were consisted of 28 patients of ulnar neuropathy at the elbow. The subjects were divided into 3 groups: focal demyelination; focal demyelination and axonal degeneration; axonal degeneration. Compound muscle action potentials were recorded from both ADM and FDI muscles and ulnar nerve was stimulated at the wrist, 2 cm distal and 8 cm proximal to the medial epicondyle. Focal demyelination were analyzed into conduction block and/or conduction slowing. RESULTS: Conduction block was observed in 13 out of 28 patients (46%) with FDI recording and 11 out of the 28 patients (39%) with ADM recording. Conduction block was found solely with FDI recording in 3 patients, whereas 1 patient showed conduction block with ADM recording only. Concomitant segmental motor conduction slowing was observed in 11 out of 13 patients with FDI recording and in 6 out of 11 patients with ADM recording. CONCLUSION: Measurements to the FDI had a higher yield of abnormality than the ADM. In some patients, only one recording muscle showed abnormal findings. Therefore, it may be useful to record from both muscles to localize ulnar neuropathy at the elbow.

OBJECTIVES: The aim of this study was to compare endogenous plasma lithium concentrations among schizophrenic patients classified by DSM-IV subtype and control groups and to investigate the correlation of endogenous plasma lithium concentration and psychotic symptoms in schizophrenia. METHODS: Schizophrenic patients were selected among psychiatric inpatients without lithium medication and then classified by DSM-IV schizophrenia subtype. Schizophrenic patient groups were composed of 15 disorganized type, 15 paranoid type and 15 undifferentiated type schizophrenic patients. The control group was composed of 15 healthy subjects without any psychiatric disease. Endogenous plasma lithium concentrations were estimated by inductively coupled plasma atomic emission spectrometer. The psychotic symptoms in schizophrenic patients were classified as positive symptoms, negative symptoms and disorganized symptoms according to andreasen classification1 about SANS and SAPS items. Endogenous plasma lithium concentration among three subtypes of schizophrenia and control group was compared, and correlation between endogenous plasma lithium concentrations and psychotic symptoms was examined. RESULTS: 1) Schizoprenic patients showed higher endogenous plasma lithium concentration than control groups (p=0.033). Endogenous plasma lithium concentrations were significantly different among three subtypes of schizophrenia (p=0.001). Compared with the control group, disorganized type showed higher endogenous plasma lithium concentration, but paranoid type and undifferentiated type were not significantly different. 2) Disorganized symptoms correlated with endogenous plasma lithium concentration (r=0.416, p=0.004), but negative symptom and positive symptom did not significantly correlate with endogenous plasma lithium concentration (r=0.202, p=0.184. r=-0.216, p=0.155). CONCLUSION: These results suggested that schizophrenic patients with disorganized symptom show the differences in utilization or distribution of endogenous lithium.

Nocardiosis is a rare infection seen most commonly in immunocompromized patients. Most patients have pulmonary involvement, but some develop disseminated infection. A 52-year-old man, treated with immunosuppressive drugs for 3 months after kidney transplantation, developed pulmonary nocardiosis and disseminated infection involving brain, skin, and both uvea. The diagnosis was made by open lung biopsy specimens showing characteristic weak acid fastness with modified Ziel-Neelsen stainig and histologic examination. Immunosuppressive therapy was continued and combination of surgical drainage of brain abscess and chemotherapy with Minocycline were successful. With the increasing number of allograft recipients and concomitant immunosuppression, the possibility of an increase in Nocardia opportunistic infections exists.

BACKGROUND: We performed a prospective, randomized, controlled trial to compare the quality, hemodynamic response, and recovery index of laryngeal mask airway (LMA) insertion after either propofol alone or co-administration of alfentanil-propofol anesthesia. METHODS: Sixty patients (ASA 1 or 2, 17-63 years) were randomly allocated to control and experimental group. Control group(Group I) was received placebo (saline), experimental groups were received alfentanil 10microgram/kg (Group II), 20microgram/kg (Group III), 30microgram/kg (Group IV). RESULTS: Loss of consciousness and LMA insertion were more rapid in patients with alfentanil 30 microgram/kg group than control group (P<0.05). In alfentanil 20microgram/kg group, loss of consciousness was more rapid than control group. Also, there were significant differences in propofol induction dose, effect site concentration on induction, and propofol maintenance dose between control and experimental group (P<0.05). CONCLUSIONS: We conclude that co-adminstration of alfentanil-propofol, especially 30microgram/kg group, compares favorably with propofol alone, although LMA removal time is prolonged.

OBJECTIVES: A day hospital has been remodeled after a vision to help psychotic patients quickly recover their psychological and social functions and lessen their induced regressions caused by long-term hospitalization, thereby enhancing their social abilities. The authors concerned once developed a day hospital model of an integrated therapy for psychotic patients suitable for Korean situation in their previous paper. Based on it, the present study was to determine how effective a day hospital would be, in comparison of the following two paired groups: day hospital group with experience of hospitalization(hereinafter abbreviated as DH group) & day hospital parents group with experience of hospitalization(hereinafter abbreviated as DH parents group) and OPD group with experience of hospitalization(hereinafter abbreviated as OPD group) & OPD parents group with experience of hospitalization(hereinafter abbreviated as OPD parents group). METHODS: During the 18-month long research period(from May to 1996 October 1997), 17 day hospital patients with experience of hospitalization & their parents and the same number of OPD patients with experience of hospitalization & their parents were corespondingly paired with at random, who identified themselves closest in the following categories: diagnosis, age, sex and function. All of them were asked to check questionnaires on their respective quality of life, insight, and their attitude about drug. Day hospital patients with experience of hospitalization and their parents were checked from the first day they were treated while OPD patients with experience of hospitalization and their parents were examined after discharge from hospital, commonly at the interval of 2 weeks, 3 months, 6 months, 12 months, and 18 months. RESULTS: 1) The quality of life scored higher in DH group than in OPD group. It turned increased significantly at the 3rd month and continued the same until the 12th month. At the 18th month, it showed a significant downturn. Meanwhile, DH group showed a significant upturn at the 3rd month and it turned down at 12 month. 2) The insight of DH group and DH parents group scored higher compared with OPD group and OPD parents group between the 3rd and 18th month, with the 3rd and 6th month showing a particular strength as well. Meanwhile, it continued unchanging for day DH group and DH parents group from the date on, of their discharge from hospital. 3) Attitude towards drugs scored higher in DH group than in OPD group at the 3rd and 6th month. It continued unchanging between the 6th and 18th month. It didn't score significantly higher in DH parents group than in their counterparts. 4) Satisfaction on the therapy started upward in DH group at the 3rd and 6th month, and scored higher in them than in their counterparts during the period form the 6th and 18th month. It started upward as well in DH parents group at the 3rd and 6th month, and scored higher in them than in their counterparts during the period form the 6th to the 18 month. 5) Number, and duration of DH group totalled lower than those by OPD group during the research period. CONCLUSION: The day hospital model, developed by the authors concerned, has proved a highly effective treatment for psychotic patients, as the data scored higher in the day hospital patients and their parents than in the OPD patients with experience of hospital and their parents in terms of "quality of life" by patients, insight, attitude toward drugs and satisfaction on its therapy.

PURPOSE: The distal clavicle has a biomechanical structure different from that of the proximal or middle 1/3 clavicle, and delayed union or nonunion occurs frequently in a distal clavicle fracture. The authors obtained favorable results from an open reduction and bone grafting of the distal clavicle nonunion. We report the results together with review of the relevant literature. MATERIALS AND METHODS: The subjects were 8 patients (average age, 38.9) who had undergone surgery for distal clavicle nonunion from August 2003 to May 2006. Nonunion occurred after surgical treatment in 4 cases, and after conservative treatment in the other 4. In all cases, the patients complained of pain. RESULTS: The mean follow-up duration was 14 months, and radiological union was observed in 8 weeks on average. In all cases, the range of shoulder joint motion was normal at the end of the follow-up observation. In the functional evaluation, 7 cases showed excellent results and 1 case showed good results. CONCLUSION: Surgical treatment is a safe and reliable treatment for distal clavicle fracture nonunion because it can achieve early rehabilitation and union.

OBJECTS: The purpose of this study was to present a day hospital model(hereinafter called as "this model") for integrated therapy, to evaluate the result of performing this model, and thus to develop day hospital model for helping psychotic patients effectively and promoting social readaptation. METHODS: The authors performed this day hospital model from 1996, May to December, A total of 25 psychotic Patients participated in this study. BPRS, Life Satisfaction Self-Rating Scale, Program Helpfulness Scale, 13 Therapeutic Factors, Scale, and Most Important Event Questionnaire were used at the start of day hospital treatment and at the end. RESULTS: The results were as follows: 1) In this model, it was possible to offer the wide treatment to heterogeneous patients who varied in age, number of admission, duration of illness, and functional level. 2) In the aspect of therapeutic effect, this model contributed for improving negative symptoms and increasing subjective life satisfaction. 3) When the patients were divided into the higher functional level group and the lower functional level group, the higher functional level group set a high value on group psychotherapy and psychodrama that were unstructured and could make patients explore their inner side deeply, But the lower functional level group did not so. Therefore dividing into two groups by functional level may be more effective for day hospital treatment. 4) Therapeutic factors were different between the periods of day hospital treatment, And in the higher functional level group, 'interpersonal learning' was important at the last period, but in the lower functional level group, 'socializing technique' was important at the last period. So long-term group psychotherapy may be more suitable for the after-care of the higher functional level group, and day care or other psychosocial rehabilitation programs may be more suitable for the after-care of the lower functional level group. 5) This model was easy to apply to Korean day hospital setting, and made staffs treat patients efficiently CONCLUSION: This day hospital model would be used effectively in Korean day hospital setting.
