Biologic resurfacing of the damaged joints is an area of great interest and clinical promise because of the limited potential ofdamaged articular cartilage healing. Several methods such as spongiolization. joint dehridement and ahrasion of suhchondral hone. perichondral grafts, and osteochondral grafts have heen used to repair cartilage defects, but the results were not satisfactory. Rccently autologous chondrocyle transplantation with a pcrioslcal patch was paid an altention for its advantage , the regeneration with hyalin cartilage. But it have many disadvantages such as too expensive cost. second staged operation, and technically difficult to isolatc chondrocytes from a small volume of donor site, so we performed that a definecl cartilaee delect in the ribbit patella was treated with transplanta1ion of in virto expanded allogenic chondrocvtes and then compared with an autologous chondrocytes transplantation. Adult rabbits were used to transplant autogenously and allogenously and allogenically harvested and in vitro cultured chondrocytes into patellar chondral lesions that had been made previously 3x 3mmin size , extending down to the calcified zone. Chondrocytes were isolated in the femoral condyle of the opposite knee or othe rabbit knee. And then enzymatic digestion ( collagenase A and DNase I ) was performed for 5 hours room temperature in a spinner bottle and cells were seeded in a 25cm2 culture flask in Dulheccos modified essential medium (DMEM), supplemented with l0% fetal hovine serum (FBS). The culture medium was changed twice weekly. After 14 days of culture, the cells were isolated hy irypsinization and transplanted into previously made chondral defects with an autogenous periosteal patch taken from the medial aspect of tibia. Healing ol' the defects was assessed by gross examination, immunohistochemical stain, and light microscope with hematoxylin-eosin stain at 8, 16, and 24 weeks. Allogenic and autologous chondrocytes transplantation significantly increased the amount of newly tormed repair tissue compared to that found in control knees in which the Jesion was solely covered hy a periosteal patch. The repair tissue, however, had a tendency of incomplete bonding to adjacent cartilage. This study shows that allogenic and autologous articular chondrocytes that have heen expanded for 2 weeks in vitro can stimulate the healing phase of chondral lesion. There is no signilicant diffcrence hetween allogenic and autologous chondrocytes transplantation.

Adventitial cystic disease (ACD) of venous system is an extremely rare condition. Very few reports of ACD in venous system have been described. In this report we discuss two cases of common femoral vein ACD that presented with a swollen leg by the obstruction of the vein. Ultrasound imaging showed the typical hypoechoic fluid filled cyst with a posterior acoustic window. Computed tomography scan and ascending venogram showed a stenosis to flow in the common femoral vein caused by an extrinsic mass. Trans-adventitial evacuation of cyst with removal of vein wall was performed for both cases. During operation we found the gelatinous material in the cysts arising in the wall of the common femoral vein and compressing the lumen. The patients were released after short hospitalization and have remained symptom free with no recurrence.

A case of Klippel-Trenaunay-Weber syndrome described originally by Klippel and Trenaunay on 1900, was presented with a brief review of literatures. The patient, 30 year-old male, said that he had noticed a reddish plaque in his right leg at the age of about 10 and had felt the asymmetricity of the limbs about 5 years later. On physical examination, he had an ulcerated sclerosing hemangioma on his right limb which is extending from medial aspect of upper one third of the lower leg to the foot. It was also associated with the varicosities just above the hemangioma, edema and hypertrophy around the right ankle, and a visible elongation of the right limb. A plane X-ray revealed osteohypertrophy of tibia and fibula without any periosteal reaction, and a soft tissue hypertrophy was also noticed around the right ankle. Histological findings of the hemangioma revealed moderate fibrosis around the proliferated vascular tissue and two of the remarkable thrombosis in the median sized vessels.

OBJECTIVE: To evaluate the efficacy of laparoscopic surgery in the treatment of deep endomtriosis, we have studied 30 cases of deep endometriosis. Endometriosis is classified into superficial(<1mm), intermediate(2-4mm), deep(>5mm) and very deep(>10mm) endometriosis by the infiltration depth from the peritoneal surface. In the treatment of deep endometriosis, medical hormonal therapy is not effective, so surgical treatment is required. There are many difficulties in surgiacal treatment ; hard lesion to excise, ditsorted pelvic anatomy after excision, easy to damage to ureter and uterine artery, and limitation for potentially morbid procedure to whom wants to conceive. Especially laparoscopic surgery in the treatment of deep endometriosis is very difficult because it is impossible to know the depth by palpation. In deep endometriosis type II, the lesion is concealed due to rectal adhesion to cul de sac, uterosacral ligament and in type III, the lesion is regarded as a small lesion or missed due to invagination into pelvic floor. The authors compared the laparoscopic surgery with laparotomy to evaluate the efficacy of laparoscopic surgery in the treatment of deep endomtriosis. METHODS: Deep endometriosis, 30 cases out of 102 cases, which were histologically comfirmed as endometriosis were studied. The authors compared the laparoscopic surgery(15 cases) with laparotomy(15 cases) in the surgical treatment of deep endometriosis for operation procedure, operation time, hospital stay and symptoms improvement. RESULTS: The mean operation time of laparoscopic surgeries in deep endometriosis was 178.7(+/-43.1)min while type I, II and III in deep endometriosis took 148.5(+/-21.2)min, 162.0(+/-30.7)min and 245.0(+/-36.1)min respectively and took a little more time than laparotomy. Mean hospital stay in laparoscopic surgeries was 5.7(+/-1.8)days and laparotomy took 10.0(+/-2.3)days that was statistically significant. CONCLUSION: If patients are chosen adequately and operator's skills are satisfactory, laparoscopic surgery is very valuable in the treatment of deep endometriosis. More datas will be required to confirm the efficacy.

BACKGROUND: Neointimal ingrowth rather than stent recoil has thought to be important for coronary arterial in-stent restenosis. Intuitively cell migration and extracellular matrix (ECM) formation seems to be important in the pathogenesis of stent restenosis. Therefore, with specific aim of identifying molecules implicated in cell migration and extracellular matrix formation, histopathologic analysis on atherectomized coronary arterial in-stent restenotic tissue was performed. METHODS: In the present study we analyzed 29 atherectomized coronary arterial in-stent restenotic tissue specimens (LAD 14, LCX 5, RCA 10) retrieved (5.7+/-5.4 months after stent deployment) from 25 patients (age 59+/-13, M/F:18/70) in whom restenosis complicated previous revascularization with Palmaz-Schatz stent. Histopathologic analysis was performed after immunostaining. Antibodies against TGF- 1, hyaluronan synthase (HAS) 1, MMP1, MMP9, urokinase type plasminogen activator, PDGF receptor were used for immunostaining. RESULTS: Myxoid tissue characterized by stellate-shaped cells embedded in a loose ECM was present in 20 out of 29 specimens, and tends to decrease over time after stenting. Foci of cell poor area (48-320 cells/mm2) in a microscopic field was present in 17 out of 29 specimens, and tends to increase over time after stenting (13/16 in <4 mo vs. 4/13 in > or =4 mo, p<0.01). Various proportions of specimens show positive stained cells with respect to each antibodies: TGF 1 in 16 out of 20:HAS1 in 10 out of 13:MMP1 in 8 out of 16:MMP9 in 4 out of 13:PDGF receptor in 12 out of 17 specimens. Abundant cells labled with certain antibodies (TGF 1, uPA, PDGF receptor) were frequently found in myxoid tissue. CONCLUSIONS: Myxoid tissue, frequently found in stent restenotic tissue, may be a biologically active tissue in terms of cell migration and of ECM formation. ECM accumulation tends to increase over time after stenting and may be important in pathogenesis of coronary arterial stent restenosis.

Recently, cell cycle regulators have been suggested as new prognostic factors of the lung cancer. In this study, we evaluated the expression of cyclin D1, p21, and p53 using the X2-test, with regard to the stage of the patients, histologic type, and histologic differentiation in the 135 cases of non-small cell lung carcinomas (NSCLC). To evaluate the confounding effects among cyclin D1, p21, and p53 on X2-test analysis, we used the Mantel-Haenzel test. The NSCLC in this study included 82 cases of squamous cell carcinoma and 53 cases of adenocarcinoma. Each nuclear staining of cyclin D1, p21, and p53 was observed in 65 cases (48.1%), in 54 cases (40.0%), and in 81 cases (60.0%) of NSCLCs, respectively. Only p53 expression was significantly associated with the stage (stage I, II, IIIa) (p<0.05) and squamous cell carcinoma (p<0.05). On the other hand, cyclin D1 expression was significantly associated with the histologic differentiation. The confounding effects among cyclin D1, p21, and p53 revealed that only p21 expression changed the relationship between p53 and stage. In this regard, further study is needed.
