OBJECTIVES: MDM-2 is an oncoprotein that inhibits p53 tumor suppressor protein. Amplication and over- expression of its protein have been observed in human malignancies, and these abnormalities have a role in tumorigenesis through inactivation of p53 function. To elucidate the role of p53 and MDM-2 protein in cervical neoplasia we investigated the expression rates of MDM-2 and p53 protein in surgically resected specimens. METHEDS: Immunohistochemical studies using anti-p53 and anti-MDM-2 protein in the paraffin embedded section of 62 cases including cervical intraepithelial neoplasm(CIN) and invasive cervical cancer were performed. RESULTS: Expression rates of p53 protein were 25% in CIN I& CINII, 20% in CINIII, and 44% in invasive carcinoma, respectively. The MDM-2 protein were 33% in CIN I & CIN II, 16% in CIN III, and 48% in invasive carcinoma, respectively. There was no evident correlation between p53 positivity and MDM-2 positivity(p>0.05). However, correlation between MDM-2 negativity and p53 negativity was statistically significant(p=0.002) CONCLUSION: These data suggest that the expression of p53 protein is presumed to be necessarily correlated with MDM-2 protein expression in cervical neoplasia.

Purpose: The incidence of isolated level III lymph node recurrence in breast cancer was evaluated, and a surgical approach with preoperative tattooing was introduced. When a suspicious infraclavicular lymph node was detected, fine-needle aspiration cytology was performed to confirm the recurrence of breast cancer. In addition, surgical excision was considered to evaluate the biological characteristics of the recurrent lesion. Methods: The treatment strategy was determined through multidisciplinary team discussions, which included breast surgeons, plastic surgeons, oncologists, radiologists, pathologists, and radiation oncologists. Preoperative tattooing was performed, and the lymph nodes were removed after splitting the pectoralis major muscle. Results: Among 85 cases of locoregional recurrence, isolated recurrent lymph nodes were observed in 25 cases. Three patients with an isolated recurrent infraclavicular lymph node received radiotherapy, and six patients underwent excision biopsy due to a history of radiotherapy for primary tumors. There was no failure in identifying the recurrent lymph node and no major complication. Conclusion The removal of isolated level III lymph node is safe, easy and can provide useful information for systemic therapy.

OBJECTIVES: Work-family conflict can arise from two opposite directions: the experiences at work interfere with family life and the experiences in the family interfere with work life. This study explored the effects of the presence of two income sources on the association between work-family conflict and job attitude. METHODS: Responses to structured survey questionnaires were received from 236 two-income families living in the Seoul Metropolitan Area. RESULTS: A differential effect was observed between single-income families and two-income families. Higher job satisfaction was related with lower work interference with family (WIF) among single-income families and with lower family interference with work (FIW) among two-income families. CONCLUSIONS: Employee welfare programs need to be expanded to enhance job satisfaction for the increasing number of two-income families.

The authors evaluated the stress response to cardiopulmonary bypass by measuring plasma Ig G, A, M and C3, C4concentrations. Anesthesia was induced with fentanyl, and all patients were underwent open heart surgery using bubble type heart-lung machine. Blood samples were obtained pre-induction, sternotomy, 10 min. and 30 min. after cardiopulmonary bypass, and 10 min. after termina tion of cardiopulmonary bypass and after transport to L.C.U. IgG, A, M and complement C3, C4concentrations were measured by Turbidmeter using Behring Turbidquant. The results were as follows: 1) Plasma concentrations of IgG, A, M and C3, C4 at preinduction period were 1345. 00+/-194. 42, 289. 10+/-100.4, 177.43+/-72.65, 59.20+/-16.33, 20.50+/-7.54 mg/dl., respectively. 2) Ten min. after cardiopulmonary bypass, the plasma concentration was significantly decreased when compared with the baseline values (p<0.01). 3) Thirty min. after cardiopulmonary bypass, the plasma concentration of the complenent C3, C4 were significantly decreascd (p<0.01). 4) In the 1ntensive care unit, Ig and complement C3, C4 were increased, but did not reach control values. Considering the above results, we conclude that the decrease of plasma Ig G, A, M and complenent C3, C4concentrations are related to mechanical stress of the cardiopulmonary bypass, and to certain activators such as denaturated protein, heterogenous RBCs, and foreign materials, etc.
