OBJECTIVE: We investigated the expression of TSP-1 and -2 in eutopic endometrium of advanced endometriosis and control patients. METHODS: The 33 endometriosis patients and 32 controls were enrolled. Endometrial samples were obtained from 65 premenopausal women aged 29-44 years, undergoing laparoscopic surgery or hysterectomy for non-malignant lesions. Sufficient samples were collected from 33 patients with endometriosis stage III and IV and 32 controls without endometriosis confirmed by laparoscopic surgery. The mRNA expression from eutopic endometrium for TSP-1 and -2 were analyzed by RT-QC PCR. RESULTS: The mRNAs of TSP-1 and -2 were expressed in eutopic endometrium from endometriosis and normal controls throughout the menstrual cycle. There were no significant differences in expression of TSP-1 and TSP-2 in eutopic endometrium between controls and endometriosis patients. CONCLUSION: Our results indicated that TSP-1 and -2 had no crucial role compared to other molecules in the regulation of angiogenesis. These findings also suggest that dysregulation of other angiogenic regulators would be concerned in pathophysiologic role in endometriosis development.

OBJECTIVE: We investigated the expression of uPA and uPAR in eutopic endometrium of advanced stage endometriosis and control patients. METHODS: The 33 endometriosis patients and 32 controls were enrolled. Endometrial samples were obtained from 65 premenopausal women aged 29~44 years, undergoing laparoscopic surgery or hysterectomy for non-malignant lesions. Sufficient samples were collected from 33 patients with endometriosis stage III and IV and 32 controls without endometriosis confirmed by laparoscopic surgery. The mRNA expression of uPA and uPAR from eutopic endometrium were analyzed by RT-QC PCR. RESULTS: The mRNAs of uPA and uPAR were expressed in eutopic endometrium from endometriosis and normal controls throughout the menstrual cycle. Uterine endometrium from women with endometriosis expresses significantly (p<0.05) higher levels of u-PA mRNA than endometrium from normal women without endometriosis in the proliferative phase. There were no significant differences in expression of uPAR in eutopic endometrium between controls and endometriosis patients. CONCLUSION: These results suggest that eutopic endometrium from endometriosis patients may be more invasive and prone to peritoneal implantation because of greater u-PA mRNA expression than endometrium from women without endometriosis. Thus, increased proteolytic activity may be one etiology for the invasive properties of the endometrium resulting in the development of endometriosis.

PURPOSE: This study was designed to find out whether protein kinase C (PKC) may affect telomerase activity in human ovarian cancers. MATERIALS AND METHODS: To determine whether PKC modulators influence PKC activities, NIH: OVCAR-3 and CUMO-2, cells were treated with PKC inhibitors, G 6976 and bisindolyl maleimide I, and PKC activator, 12-O-tetradecanoyl phorbol 13-acetate (TPA). Telomerase acti vity was determined by telomeric repeat amplification protocol (TRAP). Analysis of the expres sion of each telomerase subunits, human telomerase RNA (hTR) and human telomerase reverse transcriptase (hTERT), was performed by RT-PCR. We also examined the alternative splicing of hTERT. RESULTS: G 6976 and bisindolylmaleimide I inhibited PKC activity. Telomerase activities appeared to be affected in a time-dependent manner by these two PKC inhibitors. PKC activities were increased in parallel with telomerase activity by TPA at the low dose (10 nM), but their activities were down-regulated at the high dose (1 micrometer). RT-PCR demonstrated the presence of hTR and hTERT mRNA before and after the treatment of PKC modulators, respectively, and showed the presence of one alternatively spliced transcript and full-length hTERT transcripts. CONCLUSION: These results showed that telomerase activity was affected by PKC and suggested PKC modulation may serve as an useful tool in the regulation of telomerase activity.

OBJECTIVE: To investigate whether polymorphisms of gene encoding CYP1B1 is associated with the risk of endometriosis in Korean women. METHODS: We investigated 199 patients with histopathologically confirmed endometriosis rAFS stage III/IV and 183 control group women who were surgically proven to have no endometriosis. The genetic distribution of four different CYP1B1 polymorphisms at G119-T, G432-C, T449-C, and A453-G were analyzed by polymerase chain reaction (PCR) and restriction fragment length polymorphism of PCR products. RESULTS: We found no overall association between each individual CYP1B1 genotype and the risk of endometriosis. The odds ratio of genotype GG/GC+GG/TC+TT/AA compared to GG/CC/CC/AA (reference) was calculated as 2.06 with a 95% confidence interval of 1.003~4.216. CONCLUSIONS: This results suggest that CYP1B1 genetic polymorphism may be associated with development of endometriosis in Korean women.

PURPOSE: It is suggested that persistent hypocarbia caused by ventilator therapy could be a risk factor in PVL. The study is aimed to discover whether for preventing hypocarbia with combined use of gentle ventilation and high frequency ventilation, other factors would be causers of PVL. METHODS: Among 45 infants who were born and survived through ventilator treatment in the Fatima neonatal intensive care unit for four years from April 1996 to June 1999, 15 infants with PVL were classified as a study group and 30 without PVL as control group. The analysis was performed retrospectively with medical records. Ventilator treatment was based on the combined use of ventilation by means of the flow interruptor type of Infant Star . The aggressive weaning was performed when the clinical state, chest X-ray and arterial blood gas analysis became stabilized. RESULTS: Among 15 cases with PVL : 9 cases(60.0%) with fetal distress, 1 case(6.6%) with placenta previa, 1 case(6.6%) with placenta abruptio. In the relationship between PaCO2 variance on arterial blood gas analysis and PVL, the highest average of PaCO2 is 44.9 +/- 7.8 mmHg in the study group and 45.0 +/- 10.5 mmHg in the control group, which means there was not statistically significant difference. The PaCO2 concentration lower than 25 mmHg for three days appeared in one case in the study group. CONCLUSIONS: In cases of preventing hypocarbia by combined use of ventilation, it is suggested that the birth history and weaning method is important as risk factor of PVL.

PURPOSE: To analyze the characteristics of the interface membrane around loose Cementless Self-Cutting Titanium(CST) acetabular components. MATERIALS AND METHOD: The authors reviewed radiographs of one hundred and thirty-four hips which underwent total hip arthroplasty using Cementless Self-Cutting Titanium(CST) acetabular components, and performed histomorphological analysis on thirteen periprosthetic membranes which were taken out at the time of revision. RESULTS: After a mean follow-up of 82 months, thirteen hips(10%) underwent revision for acetabular loosening and migration. Histologic evaluation of the periprosthetic membranes showed evidence of abundant polyethylene and metal wear particles. The interface membrane was composed of a well vascularized loose connective tissue with macrophages. Polarized microscopy revealed numerous polyethylene wear particles. Ultrastructurally, numerous, variable-sized, irregular-shaped phagosomes containing electron-dense material were seen within the cytoplasm. Tissue digestion of the periprosthetic tissue eluted numerous polyethylene and metal particles. Energy dispersive X-ray spectroscopic analysis for these wear particles revealed high concentration of titanium and carbon component suggesting that the majority of the metal particles were titanium component and polyethylene particle. CONCLUSION: This study supports the concept that wear particles in total hip arthroplasty can be a strong stimulus for a foreign body response and that this reaction causes periprosthetic osteolysis and loosening.

Kimura's disease is an uncommon, chronic inflammatory disease of unknown etiology. It is an important category of reactive lymphadenopathy in the oriental population. The most common sites are the subcutis of the head and neck, and parotid gland. It's clinical course is benign nature. The treatment modalities for this disease are steroid therapy, radiation therapy and surgical excision. We experienced a case of soft tissue mass in the left arm. It was slightly tender and relatively movable. We excised the mass, which was turned out to be Kimura's disease on microscopic examination.

PURPOSE: This study was done to explore the essence and meaning of the experience of 'aging,' as a process of 40's and 50's women in Korea by applying the Parse's Human Becoming theory (2002). METHODS: Data was collected from February to April, 2013, using the phenomenological research method. Data was collected through in-depth informal interview and analyzed following Colaizzi method. After IRB permission and informed consent from the participants, all interviews were recorded with MP3 recorder and transcribed for analysis. RESULTS: Data analysis revealed 112 of meanings, 33 key subject words, 8 subject phrases, and 4 categories. The main themes were elaborated as 'going down' ('Being changed of body and mind', 'Being considered on my identity'), 'going up' ('Being expanded of productive role', 'Being transcendent multi-dimensionally'), 'pausing' ('Becoming more thoughtful about family', 'Looking back'), 'going forward again' ('Age is just a number, 'Contemplating of life and death'). Experiences in aging among women in 40's and 50's enlightened with Parse's theory of Human Becoming in terms of 'going down', 'going up', 'pausing', 'going forward again' appeared simultaneously, rather than consecutively. CONCLUSION: Women in 40's and 50's require holistic nursing intervention with physical, psychological, socio-economical, and spiritual aspects, rather than focusing on problematic physical symptom relief and prevention of further conditions. It is recommended to develop various nursing intervention considering on different environment, type of experience, and level of human becoming, individually.
