Background: This study was performed to analyze the prognostic implications of pretreatment or preoperative thrombocytosis in women with gynecologic malignancies. Material and Methods: We surveyed 2 medical databases, PubMed and EMBASE, to identified all relevant studies. A total of 14 (n=3,490) that evaluated the link between thrombocytosis and 5-year survival were included. REVMAN version 5.1 was used for our analysis and publication bias was evaluated using the Begg's funnel plot and tested by STATA 11.0. Risk ratios (RRs) with 95% confidence intervals (CIs) generated by the random effect model were used to assess the strength of any association. Results: 709(20.3%) of the 3,490 patients exhibited thrombocytosis (platelet counts > $400{\times}10^9/L$) at primary diagnosis, and their mortality was 1.62-fold higher compared with the others (RR=1.62, 95%CI=[1.28-2.05], p<0.0001). Thrombocytosis failed to have a stronger effect on the survival of advanced patients of stages III to IV in our study (n=478, RR=1.29, 95% CI=[1.13-1.48], p=0.0003), nor in women with cervical cancer in stage IB (n=1371, RR=1.73, 95% CI=[1.71-2.58], p=0.007). In addition, when adjusted for different carcinoma, it was associated with worse prognosis for all except the ones with vulvar cancer (n=201, RR=0.43, 95% CI=[0.14-1.29], p=0.13). Conclusions: This meta-analysis indicated that thrombocytosis might be associated with a worse prognosis for patients with gynecologic malignancies but without specificity or sensitivity for the ones in advanced stage. When adjusted for different gynecologic malignancies, it showed a significant effect on survival of all except vulvar cancers.

In spite of the world-wide increase of incidence of pesticide poisoning due to greater use of pesticides, the epidemiological study of pesticide poisoning in Korea has been grossly neglected. The author gained access to the medical records for two year period (1981 through 1982) from local clinics, hospitals and health centers of Kyungpook area to investigate the status of the pesticide poisoning. During these two years, there were 1,618 cases of documented pesticide poisoning, of which in 1981 were 765 and in 1982 were 853. Those in the twenties decade of age was the most frequent and the male(70%) was more liable than the female (30%). In view of manner of poisoning, occupational poisoning was 27.8%, accidental 5.6%, and suicidal 66.6%. There are three distinct groups which make up the large majority of both fatal and nonfatal cases; young children who accidentally ingest pesticides, young to middle age adult who are occupationally poisoned, and middle age to older adults who suicidally ingest pesticides. The seasonal distribution of these poisonings disclosed the peak month to be July, with August next, followed by June and September. Only 11% of cases occurred during the three-month winter season of December to February. Thus pesticide caused poison- ing was primarily a summer and early fall occurrence. During these two years, average of 67 cases of poisoning was observed monthly. Of the pesticide poisoning documented, 49% were treated with poisoning patients from local clinic and 43% from hospital. The case fatality rate of occupational poisoning was 0.9%, accidental 5.6% and suicidal 20.3%. The mean overall case fatality rate was 14.1%. Annual incidence of pesticide poisoning was 25.4 per 100,000 population in the study area. There is a nationwide need for more reliable date on pesticide poisoning. This need can only grow more acute with the passage of time because of the increasing importance of pesticides as a cause of morbidity and mortality.

This study reviewed the stuttering literature and reported the clinical experiment in stuttering intervention. There is still no single answer as to the cause of stuttering or to the most effective therapy for stutterers despite the vast amount of research. One certain thing is that we have come closer to a better understanding of the stuttering and to more effective therapy. There have been three main statements about the origins of stuttering ; biologic origins ; psychodynamic origins ; environmental-learning origins. There also have been various methods of the treatment of stuttering. Broadly, two major treatment approaches are attentive ; stuttering modification therapy and fluency shaping therapy. In this experiment, the researcher attempted to investigate complex elements that each child might have and to use an integrative approach rather than to keep the specific one. Individual subjects were evaluated by a multidisciplinary team. Initially, the subjects received individual therapy. They then were placed in group therapy. The purpose of the group therapy was to raise their fluencies to the higher communicative situation and to maintain improved fluency over time. All three subjects improved their fluencies in reading and in conversation and showed the better(SSI)scores in total stuttering behaviors. It was also discussed that it is necessary to have sensitive assessment tools to investigate each element of stuttering ; and to develop a therapy program reflecting current advanced stuttering theories.

Lately, the number of interventional radiology is increased by the extension of procedure in medical radiation, and radiation exposure may be appeared differently by interventional radiologists, it is caused increase of radiation dose for radiation worker, patient, and radiologists. This study has done a comparative analysis characteristic of radiation exposure for five radiologists who executed interventional cardiology for 303 patients in S university hospital of Gyeong-Buk from Nov. 1, 2011 to Jan. 31, 2011. The average exposure time of five radiologists was 697.95sec. The average of cumulative DAP(exp) for patients was $52,730mGycm^2$ and the average of total DAP for patients was $104,875.14mGycm^2$. The average of frames for image was 855.52 frames in acquired images, and the average of frames for images was 802.2 frames in exposure images. They were statistically significant differences (p<0.05). Exposure time, cumulative DAP(fluro), cumulative DAP(exp), total DAP, acquired image, and exposure image were high correlation except cumulative DAP(exp), and acquired runs in x-ray exposure characteristics of machine. Exposure time was a great influence on radiologist. It signified that the more exposure time lead to the more radiation dose for radiologist. Radiation dose is related to ability, experience, difficulty, and precision of procedures in interventional procedure. The number of angiography and exposure time is difficult to control by radiologists. Therefore, it is in need of reasonable system which was evaluated the real dose of medical teams in interventional proceedings. We think that self education and training are required to reduce radiation dose for radiologists and radiation workers.

Objective: This study was to establish the human embryonic stem (ES) cells derived from frozen-thawed blastocyst stage embryo that were destined to be discarded after five years in routine human IVF-ET program. Methods: Frozen-thawed and survived human blastocysts were treated by immunosurgery, and recovered ICM cells were cultured onto STO feeder cell layer and ICM colony was subcultured by mechanical dissociation into clumps. To identify ES cell, alkaline phosphatase staining and expression of Oct4 in replated ICM colonies were examined. Also, to examine the possibility of ES cell differentiation, retinoic acid (RA), basic fibroblast growth factor (b-FGF), nerve growth factor (NGF) were added in culture medium. In addition, to classify the specific cell type, differentiated cells were stained by indirect immunocytochemistry. Results: One ICM colony recovered from frozen-thawed six blastocysts was subcultured, continuously replated during 40 passage culture duration without differentiation. Subcultured colonies were strong positively stained by alkaline phophatase. When the expression of Oct4 in cultured ES colony was examined, Oct4b type is more clearly indicated than Oct4a one although there was not detected in embryoid body or differentiated cells. In differentiated cardiomyocytes from ES colony, cells were beaten regularly (60 times/min). In differentiated neural cells from ES colony, neurofilament (NF) 200 kDa protein, microtubule associated protein (MAP) 2 and ${\beta}$-tubulin of specific marker in neurons, glial fibrillary acidic protein (GFAP) of specific marker in astrocytes and galactocelebrocide (GalC) of specific marker in oligodendrocytes were confirmed by indirect immunocytochemistry. Also, muscle cells were detected by indirect immunocytochemistry. In addition, ES colonies can be successfully cryopreserved. Conclusion: This study suggested that establishment of human ES cells can be successfully derived from frozen-thawed blastocysts that were destined to be discarded, and obtained specific cell types (cardiomyocytes, neurons and muscle cells) through the in vitro differentiation procedures of ES cells.

Phosphatidyiserine (PS) is a phospholipid which plays the structural role in membranes and serves as a cofactor of signaling enzymes for diverse cellular functions. In this study, we observed that topical treatment with PS significantly decreased trans-epidermal water loss (TEWL) induced by tape-stripping in hairless mice. Also, ceramides in epidermis were increased in PS-treated group compared to vehicle-treated one in vivo. the amounts of non-hydroxyl ceramide (NHCER) (1.4 fold) and glucosylceramide (glucosylCER) (1.6 fold), in the skin of hairless mice, were increased by topical treament with PS. Also, we demonstrated that PS stimulated keratinocyte differentiation. We observed that PS treatment morphologically altered normal human keratinocyte (NHK) from the proliferating phase to the differentiating one, suggesting that PS stimulated epidermal differentiation in NHK. We also showed that the expressions of the specific markers for epidermal differentiation, involucrin (INV) (3.5 fold up) and transglutaminase 1 (TG'ase 1) (3 fold up), were significantly increased by PS treatment, compared to untreated control in vitro. In addition, topical treatment with PS resulted in a progressive increase in INV and loricrin protein levels in vivo. In conclusion, we provide the first evidence for the physiological activities of PS in skin, and we suggest that PS strengthen the epidermal permeability harrier by stimulation of keratinocyte differentiation.

To evaluate the accuracy and extent in the localization of cerebral motor coutex activation using a gradient- echo echo planar imaging(GE-EPI) compared to spin-echo echo planar iimaging(SE-EPI) on 3T MR imaging. Functional MR imaging of cerebral motor cortex activation was examined in GE-EPI and SE-EPI in five healthy male volunteers. A right finger movement was accomplished with a paradigm of 6 task and rest, periods and the cross-correlation was used for a statistical mapping algorithm. We evaluated any sorts of differenced of the time seried and the signal intensity changes between the rest and task periods obtained with two technoques. The qualitative analysis was distributed with activation sites of large veins and small veins by using two techniques and was found that both the techniques were clinically uesful for delineating large veins and small veins in fMRL Signal intensity charge of the rest and activation periods provided simmilar activations in both methods(GE-EPI : 0.93$\pm$0.11, SE-EPI : 0.80$\pm$.015) but the signal intensity in GE-EPI(133.95$\pm$15.76) was larger than in SE-EPI(74.5$\pm$18.90). The average SNRs of EPI raw data were higher at SMA in SE-EPI(48.54$\pm$12.37) than GE-EPI(41.4$\pm$12.54) and at M1 in SE-EPI(43.24$\pm$11.77) than GE-EPI(38.27$\pm$6.53). The localization of activation voxels of the GE-EPI showed a larger vein but the SE-EPI generally showed small vein. Then the analysis results of the two techniques were used for a statistacal paired student t-test. SE-EPI was found clinically useful for localizing the cerebral moter cortex cativation on 3.0T, but showed a little different activation patterns comparad to GE-EPI. In conclusion, SE-EPI may be feasible and can detect true cortical activation from capillaries and GE-EPI can obtain the large veins in the motor cortex activation on 3T MR imaging.

Purpose : The purpose of this study was to determine the effects of upper extremity volume, pain, and range of motion after participation in thera-band exercises according to the hand grip type in patients with breast cancer with upper extremity edema. We also aimed to determine the most efficient type of grip. Methods : The subjects were 10 female patients diagnosed with stage 2 breast cancer who had stage 2 lymphedema. Randomly, 5 patients each were allocated to the experimental and control groups. For six weeks, the patients in both the experimental and control groups exercised daily. In both groups, manual lymph drainage was applied for 1 hour. Afterward, patients in the experimental group placed their hands in the thera-band ring and exercised with their fingers outstretched. Patients in the control group exercised while holding the thera-band ring with a finger. Both the experimental group and the control group underwent measurements of the circumference of the upper extremity, pain, and range of motion of the shoulder joint at weeks 1, 2, 4, and 6 before and after exercise. Results : The upper arm circumference decreased by more in the experimental group in all weeks than before than that in the control group, and there was a statistically significant difference at 6 weeks. Compared with the difference between pre-exercise and 6 weeks post-exercise, the change in pain significantly decreased in the experimental group and showed a statistically significant difference. The shoulder range of motion increased in extension, external rotation, and internal rotation compared with that in the control group, and there was a statistically significant difference. Although the operating range increased in flexion and abduction, there were no statistically significant differences. Conclusion : In this study, we found that thera-band exercises with an open-hand grip are more efficient than thera-band exercises with a closed-hand grip in edema reduction, pain, and range of motion. In addition, it was found that it was more effective to continue the thera-band exercises with open-hand grip extended for at least 6 weeks rather than for a short time.
