Sleep disturbance is a one of common complaints among patients with panic disorder. However, clinicians and researchers did not give much attention to the sleep symptoms of panic disorder yet. Several previous studies suggested that the sleep disturbance in panic disorder is mediated by nocturnal panic attack. In terms of the pathophysiology of panic disorder, nocturnal panic attack seems to be closely associated with the sleep problems in panic disorder. In this article, the authors reviewed various previous studies about sleep of panic disorder and intended to give importance of evaluating sleep disturbances and nocturnal panic attack in panic disorder for both clinical and research purpose.

Flowcytometry is a very important technique for the analysis of cell properties, with the advantages of simultaneous multiparameter analysis of large cell population in a short time. Recent advances in computer science and techniques in cell preparation and staining make it more valuable for the study of cell biology and its clinical application. This study was performed to establish the techniques of flowcytometry analysis of osteosarcoma cells, to evaluate the results of the characteristics of the DNA and specific cell cycle phase of osteosarcoma cells obtained by preparation of paraffin-embedded tissue blocks, and to analyze any possible difference between cell populations lacated apart from each other in the tumor mass for making a base for further clinical application. Paraffin-embedded tissue blocks were obtained from 10 cases of primary osteosarcoma, which had undergone amputation without chemotherapy or radiotherapy. Tissue blocks obtained from the most superficial and the deepest portions of the tumor mass from the skin surface were selected respectively in each cases. To evaluate the technique and results obtained, analysis of the whole sample were performed twice in a separate setting. Satisfactory DNA histogram was obtained from 14 of 20 tissue blocks, with the values of distribution in the specific cell cycle phases. DNA aneuploidy was found in 2 cases with a DNA index of 1.6 and 1.3, and no difference in DNA ploidy by the location in tumor mass. The S-phase and G2+M phase fraction were 13.2±8.5 and 6.2±3.1 respectively, reflecting the increased cell proliferation compared with normal cell population. There was no statistically significant difference of these values between superficial and deep portions, but the difference was 9.0±9.7 with a maximum of 26.6, much greater than the difference 3.3±3.6, between the first and second set of analysis. Flowcytometry is a very useful technique in the analysis of the DNA and cell cycle phase properties, and the characteristics of DNA and cell proliferation status of osteosarcoma cells were successfully evaluated by this technique. Unsatisfactory DNA histograms were thought to be the result of inappropriate samples. To adequately evaluate the changes in the tumor mass, standardization in obtaining tumor tissue about the location in the tumor mass is suggested for future studies with flowcytometry about the properties of tumor cells.

OBJECTIVE: Heat shock protein family is related to protective mechanism of cells by environmental changes. This study was performed to evaluate the effect of cryopreservation on the heat shock protein 90 (Hsp90) expression in mouse ovarian tissue. METHODS: Cryopreservation of mouse ovarian tissue was carried out by slow freezing method. The mRNA level of Hsp90 expression in both fresh and cryopreserved mouse ovarian tissue was analyzed by RT-PCR. The protein expression of Hsp90 was evaluated by Western blot analysis and immunohistochemistry. RESULTS: The mRNA and protein of Hsp90 were expressed in both fresh and cryopreserved mouse ovarian tissue. The amount of Hsp90 mRNA was increased in cryopreserved ovarian tissue after 60 and 90 minutes after thawing and incubation. The amount of Hsp90 protein was increased in the cryopreserved ovarian tissue after 6 hours of the incubation in Western blot analysis. In immunohistochemical study, Hsp90 protein was localized in cytoplasm of oocytes and granulosa cells. Significant level of immunoreactive Hsp90 protein was detected in theca cells contrast to the weak expression in ovarian epithelial cells. CONCLUSION: This results showed the increase of Hsp90 expression in both mRNA and protein level in the cryopreserved mouse ovarian tissue. It can be suggested that Hsp90 may play a role in the protective or recovery mechanism against the cell damage during cryopreservaion.

Paragonimus westermani can cause extrapulmonary parasitism in various sites such as abdominal organ, brain, eye, periorbital tissue, heart and pericardium, mediastinum, and subcutaneous tissue. We experienced a case of subcutaneous paragonimiasis involving the breast. The lesion exhibited chronic granuloma with scattered eggs of paragonimus westermani. The adult worm was not found within the lesion which should be disintegrated a year ago by praziquantel treatment. This relatively rare involvement of ectopic paragonimiasis should be differentiated from breast malignancy.

PURPOSE: To determine the therapeutic effect between Ellman Surgitron(R) thermolysis and Argon laser thermoablation in patients with trichiais. METHODS: Thirty-one patients (46 eyes) were analyzed. We performed Argon laser thermoablation in 23 patients (35 eyes) and Ellman Surgitron(R) thermolysis in 8 patients (11 eyes). Mean age was 54. Mean follow-up period was 11 months in Ellman Surgitron(R) group, 46 months in Argon laser group. RESULTS: In Argon laser group, 17 cases of 13 patients were performed successfully in first procedure (48.6%), and cumulative success rate was 68.6% after second procedure. Eleven eyes of 6 patients (31.4%) were performed more than three times or needed to surgical intervention. On the other hand, in Ellman Surgitron(R) group, 7 cases of 5 patients (63.6%) were successfully performed in first procedure, and second procedure makes all patients allowed to be successful in treatment of trichiasis. In all two groups, complications such as lid defect, granulation tissue formation, continuous pain and erythematous skin lesions were not found. CONCLUSIONS: The success rate of Ellman Surgitron(R) thermolysis is higher than Argon laser thermoablation, and all patients in Ellman Surgitron(R) group were treated within second procedure without recurrence. The above results suggest that Ellman Surgitron(R) thermolysis is one of the good methods to treat trichiasis.
