PURPOSE: This study was designed to identify the possible mechanism of insensitivity of DU145 prostate cancer cells to the transforming growth factor (TGF)-beta1-mediated growth inhibition. MATERIALS AND METHODS: DU145 cells were treated with 4, 40, 100 pM TGF-beta1 for 3, 6, 9 days. Initially we performed the growth assay. After that, we analysed the change of cell cycle using fluorescence flow cytometry. At each time point, Western blot analysis with cell pellets was performed to investigate the change of expressions of epidermal growth factor(EGF), TGF-alpha, EGF receptor(EGFR) and TGF receptorII(TbetaR-II) proteins. RESULTS: The growth rate of TGF-beta1-treated cells was initially suppressed, but over time returned to control level. Flow cytometric analysis revealed that TGF-beta1-treated cells showed an increase in apoptotic/G1 phases, and concurrent decrease in S, G2/M phases until 6days. On day 9, however, TGF-beta1-treated cells showed a persistent increase of apoptotic unclei in spite of recovery of apoptotic/G1, S and G2/M phases. Western blot analysis showed that the intensity of EGF or TGF-alpha band decreased in dose-sependent manner on day 6. However, the intensity of each band increased up to the control level on day 9. the expression of EGFR or TbetaR-II protein did not change after treatment of TGF-beta1. CONCLUSIONS: these results suggest that EGF and TGF-alpha sould mediate in part the escape fron the inhibitory effect of TGF-beta1 in DU145 cells.

Secondary involvement of the eye and orbit occurs in about two to four percent of the patients with generalized lymphomatosis and/or other forms of lymphomatous tumors. Of the extranodal primary lesions which are more rare manifestation of the malignant lymphoma, only one percent occur in the eye and orbit. The malignant lymphoma of the orbit is consequently a relatively uncommon condition. The authors experienced a case of the malignantly mphoma of the orbital margin and treated by local radiation therapy with Co60, and the lesions regressed rapidly and completely disappeared. There has been no sign of recurrence at the orbital region, but we found that the malignant lymphomatous lesions involved in the pancreas and omentum by the surgical laparotomy. The patient died of poor course of the disease about 20 days after discharge.

Purpose:
This study evaluated changes in growth and nutritional status using the first basic and the second repeated surveys on children from North Korean refugee families who settled in South Korea.
Methods:
A total of 337 children were included in the survey. Using a structured questionnaire, the data collected included sex, date of birth, country of birth, date of entry to South Korea, and birth parents’nationality. The prevalence of stunting, underweight, wasting, and obesity were evaluated using the 2017 Korean National Growth Chart for Children and Adolescents.
Results:
The prevalence of stunting decreased from 7.9% in the first survey to 6.9% in the second survey; that of underweight decreased from 6.0% to 4.7%; and that of wasting decreased from 6.3% to 3.5%; however, these changes were not statistically significant. The prevalence of obesity significantly increased from 8.0% to 13.2% in the first and second surveys, respectively (p=0.037). There was no significant difference in the prevalence of malnutrition according to the length of stay in South Korea or the children’s country of birth. However, the prevalence of obesity was significantly higher in children with longer lengths of stay and in those born in South Korea.
Conclusion
Although children from North Korean refugee families have settled in South Korea for a long time, the rate of malnutrition is still high, and the prevalence of obesity continuously increases.

Transobturator tape (TOT) operation for urinary stress incontinence is associated with less complication rate than Tension free vaginal tape (TVT). The two procedures yield similar rates of success. The TOT is lead through the obturator foramen, reducing the risk of bladder injury as well as damage of structures located in the Retzii cave, e.g. nerves and blood vessels. However the complications of TOT procedure may have several complications associated with obturator foramen. They are the injury of obturator nerve and vessels, abscess formation on th obturator foramen, vulvar hematoma, etc. There is no report the uterine artery injury after TOT procedure so far. Recently we experienced a case of successful control of bleeding of the uterine artery after TOT operation via uterine artery embolization. Therefore we report our case with brief review of the literatures.

OBJECTIVE: Surgical drains are commonly used after the spine surgeries for minimizing hematoma formation, which can delay wound healing and may become a source of fibrosis, infection, and pain. The drain, however, may provide a direct route for infection if it is contaminated. Our objective was to survey the relationship between surgical drains and infection. METHODS: The 70 patients who had undergone single-level lumbar discectomy from April 2011 to March 2012 were retrospectively analyzed. Each patient's medical chart and magnetic resonance image were thoroughly reviewed after all the patients had been divided into the drainage and the nondrainage groups. The amounts and durations of the surgical drains in the drainage group were analyzed. Additionally, the levels of C-reactive protein, rates of infection, scores of preoperative and postoperative visual analog scale (VAS), and lengths of hospital stay after operation were compared between the 2 groups. RESULTS: In this study, 70 patients were retrospectively analyzed; out of which, 42 and 28 patients were included in the drainage and the nondrainage groups, respectively. Two of the postoperative infection cases in the nondrainage group required to undergo repeated operations. The frequency of the postoperative infection cases was higher in the nondrainage group than in the drainage group; however, there was no significant statistical difference between the 2 groups (p=0.157). CONCLUSION: Surgical drains did not elevate postoperative infection. Furthermore, drain tip cultures allowed us to detect postoperative infection at an early stage, and it led to faster initiation of antibiotics treatment.

OBJECTIVE: The aim of this study was to predict the relationship between the symptomatic disc herniation level and the osteophyte level or decreased disc height in patients with cervical disc herniation. METHODS: Between January 2011 and December 2012, 69 patients with an osteophyte of the cervical spine underwent surgery at a single center due to soft cervical disc herniation. Data including soft disc herniation level, osteophyte level in the posterior vertebral margin, Cobb's angle, and symptom duration were retrospectively assessed. The patients were divided into three groups according to the relationship between the degenerative change level and the level of reported symptoms. RESULTS: Among the 69 patients, 48 (69.6%) showed a match between osteophyte level and soft disc herniation level. Disc herniation occurred at the adjacent segment to degenerative osteophyte level in 12 patients (17.4%) and at both the adjacent and the osteophyte level in nine (13.0%). There was no significant difference in Cobb's angle or duration among the three groups. Osteophyte type was not significant. The mean disc height of the prominent degenerative change level group was lower than the adjacent segment level, but this was not significant. CONCLUSION: Soft cervical disc herniation usually occurs at the level an osteophyte forms. However, it may also occur at segments adjacent to that of the osteophyte level. Therefore, in patients with cervical disc herniation, although a prominent osteophyte alone may appear on plain radiography, we must suspect the presence of soft disc herniation at other levels.

BACKGROUND: Osteoporosis after menopause is known as a disease that needs preventive measures before medical treatment. Many patients, however, do not undergo hormone therapy to prevent it. This paper investigates some obstacles to hormone replacement therapy (HRT). METHOD: A total of 85 menopausal women who under went bone-mineralodensitometry (BMD) examination at Chuncheon Sungshim Hospital Health Care Clinic from May, 1995 to April, 1997 were the subjects of our study. We interviewed them by telephone, examined their medical records including their BMD results. We also examined what the obstacles were for them to receive HRT for osteoporosis. RESULTS: The average age of the subjects was 55.8years. Only 40 women (47%) replied that they knew beforehand the purpose of the BMD examination. The rest of the subjects replied that they simply went through the examination because it was inclusive to health items. Those who had heard of HRT for osteoporosis were only 43 people because(50.1%), and those who did not currently receive HRT amounted to 32 (74.4%). The reasons why they do not undergo the therapy were fear of cancer, no symptoms related to osteoporosis, financial difficulty, and weight gain. Among the 32 subjects, only 1 person replied that she would not receive the HRT even if the above obstacles were removed. Therefore, it seems that most of our subjects would receive HRT if such obstacles removed. Those who were currently receiving HRT were 11 people(12.9%). According to the open questionnaire, many of them replied that they do not feel any inconvenience while receiving the HRT, but some of them complained of epigastric pain, dysmenorrhea, or mastalgia. They replied that after the HRT they felt no arthralgia and felt far better in body and mind than before treatment. All the 11 people replied that they will continue to receive the HRT. CONCLUSION: The main reason why so few people received HRT for osteoporosis proved to be the lack of knowledge of the therapy. Even those who had heard of HRT complained about the negative aspects, which in fact can be overcome, and as a result a considerable number of them do not receive HRT. Therefore we conclude that in order to increase the number of patients who will undergo HRT for osteoporosis after menopause we need to strengthen education about the merits of this therapy rather than just performing BMD examination.

The unicornuate uterus is a rare type of the anomalous uteri, which is caused by failure of development of one of the mullerian ducts. This condition is usually associated with various degrees of rudimentary uterine horn. The unicornuate uterus with rudimentary horn is susceptible to many gynecologic and obstetric complications. Urinary tract anomalies, pelvic endometriosis, primary infertility are claimed to be common complaints in women with unicornuate uterus. We have experienced a case of rudimentary uterine horn adenomyosis associated with agenesis of ipsilateral kidney, pelvic endometriosis in a 13 years old girl. So we report this case with a brief review of literatures.

OBJECTIVE: Although there is no consensus on the ideal treatment of the craniocervical instability, biomechanical stabilization and bone fusion can be induced through occipito-cervical fusion (OCF). The authors conducted this study to evaluate efficacy of OCF, as well as to explore methods in reducing complications. METHODS: A total of 16 cases with craniocervical instability underwent OCF since the year 2002. The mean age of the patients was 51.5 years with a mean follow-up period of 34.9 months. The subjects were compared using lateral X-ray taken before the operation, after the operation, and during last follow-up. The Nurick score was used to assess neurological function pre and postoperatively. RESULTS: All patients showed improvements in myelopathic symptoms after the operation. The mean preoperative Nurick score was 3.1. At the end of follow-up after surgery, the mean Nurick score was 2.0. After surgery, most patients' posterior occipito-cervical angle entered the normal range as the pre operation angle decresed from 121 to 114 degree. There were three cases with complications, such as, vertebral artery injury, occipital screw failure and wound infection. In two cases with cerebral palsy, occipital screw failures occurred. But, reoperation was performed in one case. CONCLUSION: OCF is an effective method in treating craniocervical instability. However, the complication rate can be quite high when performing OCF in patients with cerebral palsy, rheumatoid arthritis. Much precaution should be taken when performing this procedure on high risk patients.
