OBJECTIVE: Early maternal separation (EMS) during the development has been known to influence the alteration of behavior in adulthood. Nitric oxide (NO) may have been implicated to play a crucial role in the neurodevelopment as an intracellular and intercellular messenger. This study was designed to investigate the neurochemical mechanism of the behavioral changes resulting from EMS during the development in juvenile rats. METHODS: Experimental group consisted of subjects that were removed and weaned from the day on postnatal day 15. Control group were the litters that experienced no EMS until postnatal day 21. On postnatal day 15 and 36, the locomotor activity (LA) was measured. On postnatal day 36 the behavioral changes in the forced swimming test (FST) were also measured. Test drugs were intraperitoneally injected including MK-801 (0.5 mg/kg), N omega-nitro-L-arginine (L-NA, 20 mg/kg), paroxetine (20 mg/kg), and bupropion (150 mg/kg). RESULTS:EMS produced the decrease of LA significantly in juvenile rats (p<0.001). Both MK-801 and L-NA increased LA in experimental group (p<0.001) and control group (p<0.05). The degree of increase was higher in experimental group than in control group. However, both paroxetine and bupropion increased LA in experimental group (p<0.001, p<0.05), but not in control group. In the FST, immobility was significantly increased in experimental group compared with control group (p<0.001). The increases of immobility in experimental group were abolished after injecting MK-801, L-NA, paroxetine, and bupropion, respectively. CONCLUSION: These results indicate that EMS during the development can lead to behavioral abnormalities in juvenile rats. The underlying neurochemical mechanism of this behavioral changes may be, in part, related to the glutamatergic NMDA-NO pathway. This suggests that glutamatergic NMDA-NO pathway vulnerable to stress may predispose to depression.

PURPOSE: This study is to examine the effect of balance taping therapy applied on the old people who suffer from arthritis upon the pain in legs and obstacle in daily activity. Methods: The research period was from Dec. 2003 to Feb. 2004, and among the old female people who visited one of the welfare halls in Seoul downtown and 4 assembly hall for old people who aged over 60 years. 30 of the experimental group and 33 of control group were optionally collected. RESULTS: The pain degree in legs and the uneasiness degree of the obstacle in the daily life of the experimental group who were treated by the balance taping was decreased than those of the control group(p=0.015, p=0.000). CONCLUSIONS: Based upon the above result, it was confirmed that the balance taping therapy has influence in decreasing the degree of the uneasiness in the leg pain and daily activity obstacle of the old people who suffer from the arthritis, and therefore it is thought that this therapy can be usefully applied for one of the nursing methods for the old patients, and besides the repeated future researches are needed.

The circadian system represents a temporal order which is mediated by the mutual coupling of oscillators and by the synchronizing effects of zeitgebers. It is known that well-being of man depends partly on the maintenance of this order, and that repeated or long lasting disturbances to it such as shift work will cause harmful effects. This study was a quasi-experimental study to test the effect of shift directions for the clinical nurses on the circadian rhythm. Fourteen nurses working at the general units of Y hospital were selected according to the established criteria. Fourteen subjects were assigned to a weekly shift but the directions of shift work were phase delay first and then phase advance or vice versa. Oral temperature, total sleeping time, frequency of sleep-wake cycle, fatigue, mental performance, and physical symptom were measured during these days except holidays. The data collection period was from April 26, 1993 to July 3, 1993. MANOVA and Wilcoxon signed rank test were used for statistical analysis. The results are summarized as follows. 1. Having worked on evening and night shifts in either phase delay or phase advance schedules, temperature rhythms of shift workers were gradually adapted to the new sleep-wake cycles. A complete adaptation to work on the night shift was achieved the sixth day of the night shift in the phase delay schedule compared to the partial adaptation to the work on the night shift in the phase advance schedule. Accordingly, by putting evening shift between day and night shifts, it will be possible for circadian rhythm to adapt easily to the night shift. 2. There were differences in the total sleeping time, frequency of sleep-wake cycle, fatigue, and physical symptom except for mental performance between night shift and day, evening shift. This indicates further that shift workers working on the night shift have a hard time adapting to the shift work compared to the other shifts. 3. Evaluating all the acrophases of temperature rhythm either in phase delay or phase advance schedules, it was shown that night to evening shift in the phase advance schedule revealed the smallest phase move. Also phase advance schedule showed poorer adaptation to shift work than phase delay schedule in connection with total sleeping time, frequency of sleep-wake cycle, fatigue, mental performance, and physical symptom. It is suggested, taken together, these findings reflect that phase delay schedule facilitated the degree of adjustment to the shift work compared to the phase advance schedule.

This project was a service-cum-research effort with a quasi-experimental study design to examine the health benefits of an integrated Family Planning (FP)/Maternal & Child health (MCH) Service approach that provides crucial factors missing in the present on-going programs. THE SPECIFIC OBJECTIVES WERE: 1) To test the effectiveness of trained nurse/midwives (MW) assigned as change agents in the Health Sub-Center (HSC) to bring about the changes in the eight FP/MCH indicators, namely; (i) FP/MCH contacts between field workers and their clients (ii) the use of effective FP methods, (iii) the medically supervised deliveries, (iv) prenatal care by medically qualified personnel, (v) medically supervised deliveries, (vi) the rate of induced abortion, (vii) maternal and infant morbidity, and (viii) preinatal & infant mortality. 2) To measure the integrative linkage (contacts) between MW & HSC workers and between HSC and clients. 3) To examine the organizational or administrative factors influencing integrative linkage between health workers. STUDY DESIGN: The above objectives called for quasi-experimental design setting up a study and control area with and without a midwife. An active intervention program (FP/MCH minimum "package" program) was conducted for a 2 year period from June 1982-July 1984 in Seosan County and "before and after" surveys were conducted to measure the change. SERVICE INPUT: This study was undertaken by the Soonchunhyang University in collaboration with WHO. After a baseline survery in 1981, trained nurses/midwives were introduced into two health sub-centers in a rural setting (Seosan county) for a 2 year period from 1982 to 1984. A major service input was the establishment of midwifery services in the existing health delivery system with emphasis on nurse/midwife's role as the link between health workers (nurse aids) and village health workers, and the referral of risk patients to the private physician (OBGY specialist). An evaluation survey was made in August 1984 to assess the effectiveness of this alternative integrated approach in the study areas in comparison with the control area which had normal government services. METHOD OF EVALUATION: a. In this study, the primary objective was first to examine to what extent the FP/MCH package program brought about changes in the pre-determined eight indicators (outcome and impact measures) and the following relationship was first analyzed. b. Neverthless, this project did not automatically accept the assumption that if two or more activities were integrated, the results would automatically be better than a non-integrated or categorical program. There is a need to assess the "intergration process" itself within the package program. The process of integration was measured in terms of interactive linkages, or the quantity & quality of contacts between workers & clients and among workers. Intergrative linkages were hypothesized to be influenced by organizational factors at the HSC clinic level including HSC goals, sltructure, authority, leadership style, resources, and personal characteristics of HSC staff. The extent or degree of integration, as measured by the intensity of integrative linkages, was in turn presumed to influence programme performance. Thus as indicated diagrammatically below, organizational factors constituted the independent variables, integration as the intervening variable and programme performance with respect to family planning and health services as the dependent variable. Concerning organizational factors, however, due to the limited number of HSCs (2 in the study area and 3 in the control area), they were studied by participatory observation of an anthropologist who was independent of the project. In this observation, we examined whether the assumed integration process actually occurred or not. If not, what were the constraints in producing an effective integration process. SUMMARY OF FINDINGS: A) PROGRAM EFFECTS AND IMPACT. 1. Effects on FP use: During this 2 year action period, FP acceptance increased from 58% in 1981 to 78% in 1984 in both the study and control areas. This increase in both areas was mainly due to the new family planning campaign driven by the Government for the same study period. Therefore, there was no increment of FP acceptance rate due to additional input of MW to the on-going FP program. But in the study area, quality aspects of FP were somewhat improved, having a better continuation rate of IUDs & pills and more use of effective Contraceptive methods in comparison with the control area. 2. Effects of use of MCH services: Between the study and control areas, however, there was a significant difference in maternal and child health care. For example, the coverage of prenatal care was increased from 53% for 1981 birth cohort to 78% for 1984 birth cohort in the study area. In the control area, the same increased from 41% (1981) to 65% (1984). It is noteworthy that almost two thirds of the recent birth cohort received prenatal care even in the control area, indicating that there is a growing demand of MCH care as the size of family norm becomes smaller. 3. There has been a substantive increase in delivery care by medical professions in the study area, with an annual increase rate of 10% due to midwives input in the study areas. The project had about two times greater effect on postnatal care (68% vs. 33%) & delivery care (45.2% vs. 26.1%). 4. The study area had better reproductive efficiency (wanted pregnancies with FP practice & healthy live births survived by one year old) than the control area, especially among women under 30 (14.1% vs. 9.6%). The proportion of women who preferred the 1st trimester for their first prenatal care rose significantly in the study area as compared to the control area (24% vs 13%). B) EFFECTS ON INTERACTIVE LINKAGE. 1. This project made a contribution in making several useful steps in the direction of service integration, namely; i) The health workers have become familiar with procedures on how to work together with each other (especially with a midwife) in carrying out their work in FP/MCH and, ii) The health workers have gotten a feeling of the usefulness of family health records (statistical integration) in identifying targets in their own work and their usefulness in carrying for family health. 2. On the other hand, because of a lack of required organizational factors, complete linkage was not obtained as the project intended. i) In regards to the government health worker's activities in terms of home visiting there was not much difference between the study & control areas though the MW did more home visiting than Government health workers. ii) In assessing the service performance of MW & health workers, the midwives balanced their workload between 40% FP, 40% MCH & 20% other activities (mainly immunization). However, 85-90% of the services provided by the health workers were other than FP/MCH, mainly for immunization such as the encephalitis campaign. In the control area, a similar pattern was observed. Over 75% of their service was other than FP/MCH. Therefore, the pattern shows the health workers are a long way from becoming multipurpose workers even though the government is pushing in this direction. 3. Villagers were much more likely to visit the health sub-center clinic in the study area than in the control area (58% vs. 31%) and for more combined care (45% vs. 23%). C) ORGANIZATION FACTORS (ADMINISTRATIVE INTEGRATIVE ISSUES). 1. When MW (new workers with higher qualification) were introduced to HSC, it was noted that there were conflicts between the existing HSC workers (Nurse aids with less qualification than MW) and the MW for the beginning period of the project. The cause of the conflict was studied by an anthropologist and it was pointed out that these functional integration problems stemmed from the structural inadequacies of the health subcenter organization as indicated below; i) There is still no general consensus about the objectives and goals of the project between the project staff and the existing health workers. ii) There is no formal linkage between the responsibility of each member's job in the health sub-center. iii) There is still little chance for midwives to play a catalytic role or to establish communicative networks between workers in order to link various knowledge and skills to provide better FP/MCH services in the health sub-center. 2. Based on the above findings the project recommended to the County Chief (who has power to control the administrative staff and the technical staff in his county) the following; i) In order to solve the conflicts between the individual roles and functions in performing health care activities, there must be goals agreed upon by both. ii) The health sub-center must function as an autonomous organization to undertake the integration health project. In order to do that, it is necessary to support administrative considerations, and to establish a communication system for supervision and to control of the health sub-centers. iii) The administrative organization, tentatively, must be organized to bind the health worker's midwives's and director's jobs by an organic relationship in order to achieve the integrative system under the leadership of health sub-center director. After submitting this observation report, there has been better understanding from frequent meetings & communication between HW/MW in FP/MCH work as the program developed. Lessons learned from the Seosan Project (on issues of FP/MCH integration in Korea). 1) A majority or about 80% of the couples are now practicing FP. As indicated by the study, there is a growing demand from clients for the health system to provide more MCH services than FP in order to maintain the achieved small size of family through FP practice. It is fortunate to see that the government is now formulating a MCH policy for the year 2,000 and revising MCH laws and regulations to emphasize more MCH care for achieving a small size family through planning practice. 2) Goal consensus in FP/MCH should be made among the health workers & administrators, especially to emphasize the need of care of "wanted" child. But there is a long way to go to realize the "real" integration of FP into MCH in Korea, unless there is a structural integration FP/MCH because a categorical FP is still first priority to reduce the rate of population growth for economic reasons but not yet for health/welfare reasons in practice. 3) There should be more financial allocation: (i) a midwife should be made available to help to promote the MCH program and coordinate services, (ii) there should be a health sub-center director who can provide leadership training for managing the integrated program. There is a need for "organizational support", if the decision of integration is made to obtain benefit from both FP & MCH. In other words, costs should be paid equally to both FP/MCH. The integration slogan itself, without the commitment of paying such costs, is powerless to advocate it. 4) Need of management training for middle level health personnel is more acute as the Government has already constructed 90 MCH centers attached to the County Health Center but without adequate manpower, facilities, and guidelines for integrating the work of both FP and MCH. 5) The local government still considers these MCH centers only as delivery centers to take care only of those visiting maternity cases. The MCH center should be a center for the management of all pregnancies occurring in the community and the promotion of FP with a systematic and effective linkage of resources available in the county such as i.e. Village Health Workers, Community Health Practitioner, Health Sub-center Physicians & Health workers, Doctors and Midwives in MCH center, OBGY Specialists in clinics & hospitals as practiced by the Seosan project at primary health care level.

Pure red cell aplasia in uncommon disorder characterized by finding of anemia, absence of nucleated red blood cell in the marrow, absence of reticulocytes in the peripheral blood and normal peripheral platelet and leukocytes counts. We experienced one case of pure red cell aplasia associated with hemolytic anemia characterized by hemoglobinuria, reticulocytopenia, and erythroid hypoplasia of the bone marrow. The cause of the illness was not definitely identified, but we concluded that this patient had simultaneous occurrence of PRCA and hemolytic anemia following administration of diphenylhydantoin after craniotomy rather than virus or bacteria induced. The simultaneous occurrence of PRCA and hemolytic anemia in uncommon and the mechanism for diphenylhydantoin induced PRCA and hemolytic anemia is unclear.

Joubert syndrome is a rare hereditary brain malformation and transmitted as an autosomal recessive tarit. This disorder is clinically characterized by episodic tachypnea and apnea, abnormal ocular movements, developmental delay and ataxia. Anatomic anomalies include cerebellar vermal agenesis with dilatation of the fourth ventricle. Symptomatic onset is in the neonatal period and prognosis is severe. We have experienced a case of Joubert syndrome in a 3months old male patient, who manifested by developmental delay, periodic tachypnea and apnea, abnormal eye movement, generalized hypotonia and hypoplasia of cerebellar vermis with the 4th ventricular dilatation on brain MRI. We presented this case with a brief review of literatures.

PURPOSE: To evaluate the size of normal pons and cerebellum in vivo and the change in size according to age, and to compare those with measurement of the diseased pons and cerebellum. MATERIALS AND METHODS: 121 normal adults(M:F=54:67), 5 patients with OPCD and 19 patients with WallerJan degeneration were studied. The normal group was divided into 5 subgroups according to the age (ranged from 20 to 72 years). 1.5T GE Signa MR unit was used. On axial plane, the AP(A) and transverse(B) diameters of the pons, the size of the middle cerebellar peduncle(C), and transverse diameter of the posterior fossa(D) and the cerebellum(E) were measured. On midsagittal plane, the longitudinal(F) and AP(G) diameters of the basis pontis were measured. The ratios of E/D and F/G were calculated. The student t test was used for statistical analysis. RESULTS: C, E and F/G were 15.5mm+/-1.3, 99.8mm+/-4.3 and 1.63+/-.10, respectively. F/G, H/I, and H/J were larger in male(p<.01). All data of the pons showed no statistically significant differences among age groups. E of the seventh decades was shorter than that of the third decades(p<.05). C(12.7 mm+/-1.4) in OPCD and F/G(1. 81+/-.10) in Wallerian degeneration(p<.01) showed the most significant differences when they were compared to the normal. CONCLUSION: Although the cerebellum decreased in size with age, the pons maintained its size up to eighth' decades. The measurement of middle cerebellar peduncle on axial plane (C) and the ratio of basis pontis on midsagittal plane (F/G) were important in the evaluation of OPCD and WallerJan degeneration, respectively.

Male breast cancer is very rare, with the incidence of 0.15-1% of all breast cancers and less than 1% of all cancers in men. The prognosis of male breast cancer is poorer than that of female because the median age of detection of the disease is in more late stage. It usually involves higher axillary lymph nodes. We report two cases of male breast cancer to describe characteristic mammographic and ultrasonographic findings and to compare with the findings of gynecomastia.
