We implanted intraocular lenses in 41 eyes of 41 patients with traumatic cataract without associated retinal injury. All the enrolled patients had sustained injury visited the Incheon Gil Hospital between August 1988 and June 1992. We analyzed age and sex distribution, mode and site of injuries, associated injuries, postoperative complications, methods of operation, final visual results and causes of decreased vision. Nineteen patients(46.4%) achieved final visual acuity of 0.5 or better, 11 patients(26.8%) between 0.1 and 0.5, and the remaining 11(26.8%) below 0.1. Major visual prognostic factors were associated ocular injuries, the state of the posterior lens capule, intraoperative and early postoperative complications. The interval between the first and second operation had little effect on the final vision.

STUDY DESIGN: The lumbar segmental motions were analysed in asymptomatic volunteers. OBJECTIVES: To obtain normative data on flexibility and Graf's instability degree in sagittal plan of the normal lumbar spine. SUMMARY OF LITERATURE REVIEW: Although several clinical and radiological measurement tech niques are available, little is known about the normal range of lumbar spine motion. As a consequence, the diagnostic evaluation of radiographs are frequently based on subject opinions rather than object reality. MATERIALS AND METHODS: The authors have checked lumbar flexion-extension Yiews of 95asymptomatic volunteers who were divided into 5 groups by the age, and then their flexibility and Graf's instability degree were calculated by Graf's method with using Graf/Bar Mark II(digitalizing table) and personal computer program(RachisR). Evaluation of the sexual difference and comparison of the difference of each age group in spine level were done RESULTS: 1. There were significant differences in flexibility among age groups(p<0.05) and highest flexibility was observed in group 1 (age: 15-19yrs) and 15-19 segment 2. Flexibility was not different between male and female(p>0.05). 3. Graf's instability degree was not different among 5 age groups(p>0.05), and between male and female(p>0.05). 4. The mean Craf's instability degree was below 8o in L2-3, L3-4, and L4-5 segment, but above 8 in L5-S1 segment(male: 11.62+/-9.27 , female. 11.11+/-8.70). CONCLUSIONS: Although we observed small subjects, these results are the basic steps toward more objective and careful interpretation of flexibilty and Graf's instability degree.

OBJECTIVE: Recently, microdissection of tissue sections has been used increasingly for the isolation of morphologically identified homogeneous cell populations, thus overcoming the obstacle of tissue complexity for the analysis cell-specific expression of macromolecules. The aim of the present study was to establish the minimal conditions required for the RNA extraction and amplification from the cells captured by the laser captured microdissection. METHODS: Mouse ovaries were fixed and cut into serial sections (7 micrometer thickness). Oocytes were captured by laser captured microdissection (LCM) method by using PixCell IITM system. The frozen sections were fixed in 70% ethanol and stained with hematoxylin and eosin, while the paraffin sections were stained with Multiple stain. Sections were dehydrated in graded alcohols followed by xylene and air-dried for 20 min prior to LCM. All reactions were performed in ribonuclease free solutions to prevent RNA degradation. After LCM, total RNA extraction from the captured oocytes was performed using the guanidinium isothiocyanate (GITC) solution, and subsequently evaluated by reverse transcriptase -polymerase chain reaction (RT-PCR) for glyceraldehyde-3-phosphate-dehydrogenase (GAPDH). RESULTS: With the frozen sections, detection of the GAPDH mRNA expression in the number of captured 25 oocytes were not repeatable, but the expression was always detectable from 50 oocytes. With 25 oocytes, at least 27 PCR cycles were required, whereas with 50 oocytes, 21 cycles were enough to detect GAPDH expression. Amount of the primary cDNA required for RT-PCR was reduced down to at least 0.25 microl with 50 oocytes, thus the resting 19.75 microl cDNA can be used for the testing other interested gene expression. Tissue-to-slide, tissue-to-tissue forces were very high in the paraffin sections, thus the greater number of cell procurement was required than the frozen sections. CONCLUSION: We have described a method for analyzing gene expression at the RNA level with the homogeneously microdissected cells from the small amount of tissues with complexity. We found that LCM coupled with RT-PCR could detect housekeeping gene expression in 50 oocytes captured. This technique can be easily applied for the study of gene expression with the small amount of tissues.

We have treated the open tibia shaft fractures, especially Gustilo type II, with unreamed interlocking intramedullary nail. In cases combined with soft tissue damage around fracture site, maintaining rigid internal fixation and preserving endoosteal blood supply is important in union of fracture and soft tissue healing. We have analyzed 18 cases of Gustilo type II open tibial shaft fractures managed with intramedullary nailing without reaming since 1991, the follow-up period was average 22 months. Most of the fractures were the result of moderate to high-energy trauma. In all 18 cases, nails were inserted via closed method. Static interlocking nailing was used in all cases. In 16 cases, union of the fracture was achieved from 16 to 25 weeks(average 23 weeks). In the other 2 cases, union was achieved in 7 months. There was no serious postoperative complication except one skin infection with skin defect managed by skin flap and one failure of the interlocking screw. These results are comparable with those obtained from other forms of fixation, including immobilization with a cast, reamed intramedullary nailing, and external fixation.

Five cases of ovarian serous borderline tumor associated with multiple peritoneal implants were analysed. The age of 5 patients ranged from 34 to 45(mean: 39) years at the time of diagnosis. Two patients presented with secondary infertility underwent hyperstimulation of the ovary under the in vitro fertilization program. One patient was presented with abdominal pain and the remaining two with lower abdominal mass accompanied by abdominal pain. Serous surface papilloma of borderline malignancy, involving one or both ovaries, was present in all 5 cases and papillary serous cystic tumor of borderline malignancy was associated simultaneously in one or both ovaries in all cases. Marked adhesions between the pelvic organs, and multiple granularities and nodularities of the omentum and peritoneum were noted. Microscopically, the peritoneal lesions were composed of noninvasive implants of tumor cells and pasmmoma bodies on the surface of entire pelvic and abdominal organs. Flow cytometric analysis of nuclear DNA content from paraffin-embedded tissue fo primary ovarian tumor classified as aneuploidy in 3 cases and as diploidy in 2 cases. The DNA index of the aneuploid tumors ranged from 1.21 to 1.37. Four patients underwent hysterectomy, bilateral salpingo-oophorectomy and partial omentectomy in which two were followed by chemotherapy and one case underwent bilateral salpingo-oophorectomy.
