Chymopapain and collagenase are well known chemonucleolytic agents for lumbar disc herniation. However, these enzymes have serious problems occasionally, such as severe neurotoxicity or anaphylaxis even fatal to patients. Chondroitinase ABC, a metabolic product of Proteus vulgaris, has a specific action on the proteoglycans of the nucleus pulposus, but rarely no effect on the intrathecal nerve tissues of vessels. Seventy eight rabbit lumbar discs were evaluated radiographically and histologically after injection of chondroitinase ABC 40U/ml per disc and compared with buffer injected group and nonigected control group. There was considerable disc space narrowing of the chondroitinase ABC injected group which was verified radiographically and histologically(p < 0.01). A zone of Safranin 0 depletion was present in the ventral anulus fibrosus adjacent to the nucleus pulposus in all treated discs, indicating proteoglycan loss. On electron microscopic findings there were collapse of chondrocytes and notochordal cells. All of these findings are corresponding to the evidence that chondroitinase ABC may be another chemonucleolytic agent by decreasing disc volume and thereby decompressing spinal cord or nerve roots. All histologic effects of chondroitinase ABC were confined to intervertebral disc tissues. Chondroitinase ABC deserves to be a study object for the alternative of chemonucleolysis.

Objective: Percutaneous vertebroplasty (VP) has been used for the safe treatment of osteoporotic compression fracture. However, cement leakage is the most common complication. To reduce the leakage of bone cement, we did the gelfoam embolization during VP. The purpose of this study is to compare the safety and feasibility of different two gelfoam embolization technique during VP. Methods: Total 127 patients (146 level) who had the thoracolumbar osteoporotic compression fracture were enrolled. Group A was treated by gelfoam-only technique and, Group B was treated by gelfoam with venography technique. We compared the incidence of bone cement leakage between two groups using post-operative computed tomography scan and X-ray. Results: Seventy-four patients (81 levels) were treated with gelfoam-only technique (A), and 53 patients (65 levels) were treated with gelfoam with venography technique (B). There were 22 leakages on group A, and 19 leakages on group B. There was no statistical significant difference between two groups (Chi-square test, p-value =0.958). Incidence of leakage to spinal canal was 11 levels in Group A, 3 levels in group B, and there was statistical significant difference (Fisher's exact test, p-value=0.027). Conclusion Complication induced by the bone cement leakage are the most careful point during VP. Gelfoam embolization with venography is very easy and safe method. Gelfoam with venography technique could make lower the incidence of cement leakage to spinal canal.

A 26-year-old Korean man had an erythematous scaly plaque on his right thigh for fifteen years. He was diagnosed with chronic eczema and treated with topical steroid, but no clinical improvement was obtained for 15 years. Laboratory studies including complete blood cell count, urinalysis, liver and renal function test, and peripheral blood smear were normal. A biopsy specimen showed hyperkeratosis, acanthosis, and mononuclear cellular infiltration in the epidermis. These cells had a perinuclear halo and showed a Pautrier's microabscess like configuration. In the dermis, there was a band like infiltration of inflammatory cells. Infiltrates of the epidermis were negative for leukocyte common antigen(CD45) and positive for Pan T cell(CD45RO). He was treated with topical PUVA twice a week for twelve weeks. Clinical and pathological improvements were obtained. We propose PUVA may be a useful therapeutic modality to treat Woringer Kolopp disease.

In the present study, we attempted to reveal the response of lens on induced traumatic cataract which were removed the anterior capsule with 0.5 mm, 1.0 mm, 2.0 mm, 4.0 mm size in six rabbits. We examined histopathological change of the wounded lenses by means of the slit-lamp and electronmicroscope. We found opacities in wounded area increased regardless of wound diame-ter. Electronmicroscopic findings were similar to normal single-layer cuboidal anterior epithelial cells at 0.5 mm, 1.0 mm, 2.0 mm, 4.0 mm one day after injury. There were, however, elongated epithelial cells with abun-dant fine filaments and slightly edematous lens fiber cells in 0.5 mm, 1.0 mm, 2.0 mm groups at 1 week after injury. These were observed as a small superficial scars at the wound site. We considered these changes as an effort of lens to delay the progression to the total cataract . We noted the widening of intercellular spaces, loss of cell membrane, decrease of intracel-lular organelles and severe change of the lens fiber rows in 4.0 mm group at 3 weeks after injury. We observed these changes as the total cataract in gross. Taken together, we revealed that lens epithelial cells in 0.5 mm, 1.0 mm, 2.0 mm in wound diameter stop the progression toward to the total cataract. However, lens epithelial cells at 4.0 mm in wound diameter could not obstruct the progression toward to the total cataract. We documented different stages of cataract formation and microstructure of the wounded lens, which have different wound sizes.

OBJECTIVE: The goal of this study is to determine the efficacy of rapid karyotyping from fetal ascitic fluid. METHODS: In three cases of isolated fetal ascites diagnosed by prenatal ultrasonography, ultrasound guided fetal paracentesis and amniocentesis were performed and successfully obtained. Fetal karyotyping in each case at 29, 30 and 32 weeks gestation using modified lymphocyte culture method was conducted. RESULTS: The chromosomal analysis was successful within 72 hours and abnormalities were detected in two cases and revealed trisomy 21 in each case. Our study demonstrated that the majority distribution of white blood cells was lymphocytes which ranged from 2.1 * 10(6) cells/ml to 3.7 * 10(6) cells/ml and the cell density for culture was at least than 0.35 * 10(6) cells/ml. CONCLUSION: The use of ascitic fluid as a cell source to achieve rapid fetal karyotyping can be valuable when cordocenteis or amniocentesis would be technically more difficult, or when rapid result is required for planning of perinatal management at late second or third trimester gestational age.

Locally advanced non-small cell lung cancer (LA-NSCLC) is composed of heterogeneous subgroups that require a multidisciplinary team approach in order to ensure optimal therapy for each patient. Since 2010, the National Comprehensive Cancer Network has recommended chemoradiation therapy (CRT) for bulky mediastinal disease and surgical combination for those patients with single-station N2 involvement who respond to neoadjuvant therapy. According to lung cancer tumor boards, thoracic surgeons make a decision on the resectability of the tumor, if it is determined to be unresectable, concurrent CRT (CCRT) is considered the next choice. However, the survival benefit of CCRT over sequential CRT or radiotherapy alone carries the risk of additional toxicity. Considering severe adverse events that may lead to death, fit patients who are able to tolerate CCRT must be identified by multidisciplinary tumor board. Decelerated approaches, such as sequential CRT or high-dose radiation alone may be a valuable alternative for patients who are not eligible for CCRT. As a new treatment strategy, investigators are interested in the application of the innovative radiation techniques, trimodality therapy combining surgery after high-dose definitive CCRT, and the combination of radiation with targeted or immunotherapy agents. The updated results and on-going studies are thoroughly reviewed in this article.
