One hundred eighty-eight patients with avascular necrosis of the femoral head in adults, who were admitted and treated in Department of Orthopedic Surgery, Seoul National University Hospital between January of 1965 and May of 1985 are investigated in terms of the history, clinical data and laboratory examinations. And, the following results were obtained. 1. The incidence was higher in the 5th decade and the sex ratio between male and female was 3.3:l. 2. 106 cases (56%) had the bilateral hip involvement. 3. The most frequent etiological factor was alcohol (72 cases, 38%), followed by trauma (35 cases, 19 %), and steroid (32 cases, 17%). 4. Underlying diseases in steroid-induced avascular necrosis of the femoral head were dermopathy (9 cases), nephropathy (4 cases), pain over other joints (5 cases), systemic lupus erythematosus (2 cases), etc. 5. The time intervals between etiological events and appearances of clinical symptoms were 2 years and 3 months in the steroid induced cases, 1 year and 1 month in trauma induced ones, 2 years and 1 month in femur neck fracture cases, 2 years and 2 months in Caissons disease, and 3 years in post-irradiation 6. Bone scan was valuable in the early diagnosis of avascular necrosis of the femoral head. 7. Selective femoral head angiography show narrowing of lateral femoral circumflex artery, narrowing or obstruction of medical femoral circumflex artery, and obstruction of superior retinacular artery. 8. It is suggested that minor trauma and osteoporosis could make micro-fracture, resulting avascular necrosis of the femoral head, and the vascular change is secondary to the avascular necrosis.

For many years, members of medical profession have believed that the shorter symptoms to diagnosis interval(SDI) might be related to early stages and that the prompt treatments might improve survival rates in cancer patients. But this notion has been challenged by many researches for many years. This study was conducted to investigate the effects of SDI on the cancer survival for 221 stomach cancer cases, 106 lung cancer cases, 74 liver cancer cases and 59 cervix cancer cases. These cancer cases are registered ones in Kanghwa Cancer Registery Program from 1987 to 1991. Relationships among SDI, stages of cancers, operation rates, and survival were analysed. Results are as follows: 1. SDI was not related to stages of cancer. There were no difference in the distribution of stages among five SDI subgroups. 2. This data did not support that SDI affects the survival of stomach cancer patients. The cancer stages did affect survival in stomach cancer patients though. 3. Our data did not support that SDI affects cancer survival. A Cox proportional hazard model showed that SDI does not play a important role in cancer survival controlling age, gender, stage and other variables in the model. Further studies are highly expected to clarify the relationships between SDI and cancer survivals. Researches with bigger sample size and more sophisticated variables would be needed.

PURPOSE: Chlamydia trachomatis (C. trachomatis) is a well known cause of non-gonococcal urethritis (NGU). No other microorganism has been shown to cause any larger proportion of the remaining NGU cases. As a possible causative organism of NGU, we wanted to evaluate the detection rate of Mycoplasma genitalium (M. genitalium) and its role in NGU using polymerase chain reaction (PCR). MATERIALS AND METHDS: From June 1998 to July 2000, we examined a total of 116 men. Of these men 70 had symptoms and signs compatible with urethritis and 46 were for normal control. In the patient group, two urethral discharge or swab specimens were collected. One was used for Gram stain to detect Gram negative intracellular diplocci. The other was subjected to PCR for C. trachomatis and M. genitalium. In the control group, urethral swab specimen was used to detect C. trachomatis and M. genitalium by PCR based assay. RESULTS: Gonococcal urethritis (GU) was diagnosed in 14 cases (20.0%). Detection rates of M. genitalium and C. trachomatis in urethritis group were 8.6% (6/70), 18.6% (13/70). M. genitalium and C. trachomatis were detected in 7.1% (1/14), 14.3% (2/14) of GU and 8.9% (5/56), 19.6% (11/56) of NGU. Detection rate of M. genitalium in chlamydia-negative NGU was 11.1% (5/45). No patient positive for M. genitalium had a simultaneous chlamydia infection. In control group with no urethral symptom or sign, M. genitalium and C. trachomatis were not detected at all. Compared with chlamydia- positive NGU, M. genitalium-positive urethritis exhibited higher recurrence rate. CONCLUSIONS: M. genitalium was detected in 8.9% of NGU and 11.1% of non-chlamydia NGU. This study suggests that M. genitalium may be one of the causative organisms in NGU. Further studies will be necessary to define its role in NGU.

PURPOSE: This study investigates nurses' organizational commitment, internal marketing, and occupational satisfaction depending on their age, martial status, clinical experience and income. METHODS: The subjects of this study were 350 nurses from six hospitals in Jeolla-do. The t-tests were used to analyze the differences in internal marketing, occupational satisfaction, and organizational commitment depending on their age, marital status, career, and income. The relationships among internal marketing, occupational satisfaction, and organizational commitment were analyzed by the path analysis. RESULTS: The results of this study showed that organizational commitment was correlated with age, clinical experiences, and income, but not significantly associated with martial status. Education and training policy, benefit system, and fairness of the internal marketing were influencing factors on occupational satisfaction. These factors were correlated with organizational commitment through occupational satisfaction. CONCLUSION: This study addressed the relationships among nurses' internal marketing, occupational satisfaction, and organizational commitment. Based on the results, it is suggested that hospital organizations introduce more diverse incentive policies to enhance nurses' occupational satisfaction and organizational commitment.

PURPOSE: The purpose of this study was to identify the factors influencing sexual assertiveness in dating college students. METHODS: With a cross-sectional survey design, 468 college students who have had dating experiences were recruited and answered questionnaires. Data were analyzed using t-test, ANOVA with Scheffe? test, Pearson's correlation coefficients, and multiple regression. RESULTS: The sexual assertiveness of college students showed significant results: positive correlations with self-assertiveness and negative correlations with traditional sexual attitude, gender role stereotypes. Significant predictors of sexual assertiveness were traditional sexual attitude, gender role stereotypes, and self-assertiveness. These variables explained 37% of the variance in sexual assertiveness. CONCLUSION: Findings suggest that it is important to identify and improve communication patterns in relation to sexual assertiveness. There is a need for sex education programs for college students that are relevant and effective.

The purpose of this study was to evaluate the influence of high dose carbon tetrachloride (CCI4) on the hepatotoxic effect of dimethylnitrosamine (DMN) which induces acute hemorrhagic necrosis in liver. Rats were injected intraperitoneally DMN dissolved in physiologic saline by a dose of 40 mg/kg. For changes related to CCI⁴ pretreatment, rats were injected intraperitoneally CCI⁴ dissolved in olive oil by a dose of 0.4 mg/kg, and then injected DMN. The livers were extracted from the rats 3, 6, 12, 24, 48, 72, and 120 hours after CCI⁴ and/ or DMN injection. Liver tissues were examined with light and electron microscopes. The results were summarized as follows; Light microscopic findings: Severe centrilobular hemorrhagic necrosis developed from 12 hours after injection of DMN and continued to 120 hours. On injection of DMN after CCI4 pretreatment, Massive necrosis occurred early. But active regenerative changes were produced in 24 hours. In 120 hours, the liver recovered in almost normal appearance. The degree of necrosis in pretreated group was similar to that in DMN injection only, and the time of recovery was faster in pretreated group. Electron microscopic findings: The early change was mainly disorganization of RER in DMN injection, and clumping and vesicular dilatation of ER in injection of CCI4. In pretreatment group, the early change was similar in appearance with CCI4 group, but severer in degree. According to the results, it was revealed that acute toxic effect of DMN was recovered more rapidly in pretreatment group. Thus it was suggested that CCI4 had protective effect in DMN hepatotoxicity.
