Journal of the Korean Ophthalmological Society 1998;39(8):1879-1884
Authors compared surgical results of neurologic impaired esotropes(n=23, group I) and normal infantile esotropes(n30, groups II) following bilateral medialrecti recession. Inclusion criterias were earlier onset of esotropia than 6 months of age, more than 25 PD with comitant strabismus, and follow-up time more than 6 months. The mean age of each group was 26.3months in group I. 32.5 months in group II and mean preoperative deviation was 42.4PD, 43.2PD and mean follow-up was 20.6 months, 20.2 months respectively. We defined success as alignment maintained within 10 PD of orthophoria. Success rate was 78.3% and overcorrection was 21.7% in group I while success rate was 83.3%, with undercorrection of 16.7% in group II at the one month postoperatively(p=0.006). Success rate was 30.8% and overcorrection was 53.9% in group I and success rate 66.7% in group II at the 24 months postoperatively(p=0.013). We conclude that neurologic impaired esotropic patients showed more overcorrection and more poor long-term success rate than infantile esotropes following bilateral media recti recession.

We compared Healon which is widely used as a viscoelastic with Hyal 2000, recently produced in Korea. We evaluated anterior chamber reaction, intraocular pressure, and specular microscopy after injection of 0.2ml Healon and Hyal 2000, respectively, into anterior chamber of 20 cats, and performed light microscopy and scanning electron microscopy 8 weeks later. We calculated the corneal swelling rate after 0.2ml Healon and Hyal 2000 were coated on the corneal endothelium of 10 rabbits and GBR solution with 0.5mM H2O2 was perfused. Anterior chamber reaction disappeared after 2 days of injections, and intraocular pressure(IOP) increased after 6 hours of infection but normalized after 24 hours in both 2 groups. Corneal endothelial cell count was 4956cells/mm2 in the Healon group and 5021cell.mm2 in the Hyal 2000 group on the first post-injection day. and 4827cells/mm2 and 4810cell/mm2, 1 week later, without a statistical difference. The histologic abnormality was not detectable in light microscopy or scanning electron microscopy in both groups. The corneal swelling rate with Healon was 15.85micrometer/hr and 12.72micrometer/hr with Hyal 2000, while it increased to 69.29micrometer/hr and 67.51micrometer/hr in controls(p<0.05), respectively. The clinical findings showed no difference and histologic findings appeared normal in both the Healon and the Hyal 2000 groups. The inhibitory effect on the corneal swelling was similar during in vitro perfusion in both groups.

PURPOSE: The purpose of this study is to investigate the correlations of various kinetic parameters derived from the time intensity curve in a xenograft mouse model injected with a prostate cancer model (PC-3 and LNCaP) using an ultrasound contrast agent with histopathologic parameters. MATERIALS AND METHODS: Twenty nude mice were injected with human prostate cancer cells (15 PC-3 and five LNCaP) on their hind limbs. A bolus of 500 microL (1 x 10(8) microbubbles) of second-generation US contrast agent (SonoVue) was injected into the retroorbital vein. The region of interest was drawn over the entire tumor. The time intensity curve was acquired and then fitted to a gamma variate function. The maximal intensity (A), time to peak (Tp), maximal wash-in rate (washin), washout rate (washout), area under the curve up to 50 sec (AUC50), area under the ascending slope (AUC(in)), and area under the descending slope (AUC(out)) were derived from the parameters of the gamma variate fit. Immunohistochemical staining for VEGF and CD31 was performed. Tumor volume, the area percentage of VEGF stained in a field, and the count of CD31 (microvessel density, MVD) positive vessels showed correlation with the parameters from the time intensity curve. RESULTS: No significant differences were observed between the kinetic and histopathological parameters from each group. MVD showed positive correlation with A (r=0.625, p=0.003), washin (r=0.462, p=0.040), AUC50 (r=0.604, p=0.005), and AUC(out) (r=0.587, p=0.007). Positive correlations were also observed between tumor volume and AUC50 (r=0.481, p=0.032), washin (r=0.662, p=0.001), and AUC(out) (r=0.547, p=0.012). Washout showed negative correlations with MVD (r=-0.454, p=0.044) and tumor volume (r=-0.464, p=0.039). The area percentage of VEGF did not show any correlation with calculated data from the curve. CONCLUSION: MVD showed correlations with several of the kinetic parameters. CE-US has the potential for prediction of tumor vascularity in a prostate cancer animal model.

Endothelial cell have been shown to play an active role in many phases of immunologic process, including binding of T lymphocytes, neutrophils, platelets, and monocytes to the endothelium, as well as phagocytosis. Endothelial cells can also serve as targets that undergo cell injury. The most prominent mediators of endothelial cell activation are IL-1beta and TNF-alpha. VLA-4 was first identified as an endothelial cell surface receptor. We performed the culture of endothelial cells derived from human glomerular capillaries and studied the cytokine-regulated expression of VCAM-1, and the effect of dexamethasone and TGF-beta on the cytokine induced VCAM-1 expression using ELISA method. Expression of VCAM-1 was not detectable above background level in the basal unstimulated state. However, VCAM-1 was rapidly induced after exposure to IL-1beta (5ng/ml) or TNF-alpha (1, 10ng/ml) (O.D.=1.76+/-0.15, 1.95+/-0.35, 1.88+/-0.17, mean+/-S.E., control=0.36+/-0.028, n=8-24, P<0.05). But IFN-gamma did not increase the expression of VCAM-1. Addition of dexamethasone (10 micrometer) and TGF-beta1 (1ng, 10ng/ml) blunted IL-1beta and TNF-alpha induced expression of VCAM-1. Therefore, VCAM-1 could be inducible in human glomerular endothelial cells, and it was regulated by dexamethasone and TGF-beta1. The negative findings in histopathology may reflect the transience of VCAM-1 expression and does not necessarily exclude an important role of this molecule in the early stages of renal disease.

Mature cystic teratoma of the ovary are often diagnosed in women of reproductive age and account for 5-25% of all ovarian tumors. Due to continuous growth and possible complications, namely rupture, torsion, infection and malignancy, teratoma should be removed surgically. More complications are occurred in huge teratoma. We present here a case of a delayed operated huge mature cystic teratoma without any complication with a brief review of the literature.

BACKGROUND: In the presence of anticipated or established acute tubular necrosis (ATN) immediately after cadaveric kidney transplantation, induction with monoclonal or polyclonal antibody is recommended in preparation of increased risk of acute rejection caused by ATN. Tacrolimus is a potent immunosuppressive agent than cyclosporine. In this study, we analyzed retrospectively the clinical outcome of patients who had taken tacrolimus as a replacement of cyclosporine in the period of delayed graft function(DGF) to determine the eligibility of tacrolimus instead of antilymphocyte antibody in this situation. METHODS: Between March 1, 1991 and August 31, 2000, DGF developed in eighteen first cadaveric renal transplant recipients in our center. During DGF period, twelve patients received tacrolimus based immunosuppression without OKT3. We reviewed the complete clinical course of the 12 patients. RESULTS: Among the 12 patients, 1 patient underwent graft nephrectomy at postoperative 27 days, because of poor renal function and concomitant aspergillosis infection. In the remaining 11 patients, however, for whom tacrolimus was maintained continuously without OKT3 therapy, renal function was recovered successfully. One acute rejection developed at postoperative 15 months. One patient died at postoperative 5 months with functioning graft. One-year graft survival rate was 83%. CONCLUSION: Tacrolimus could be used in replacement of cyclosporine for the prevention of acute rejection in DGF. This could provide a graft survival comparable to that by the monoclonal or polyclonal antibodies without the potential risk of life- threatening side effects in this situation.

Maximizing peak bone mass is advocated as a way to prevent osteoporosis. To evaluate the peak bone mass and the affecting factors in Korean women, we analyzed bone stiffness in 116 middle school students, 118 high school students and 115 female college students by using the Achilles densitometer (Lunar Corporation). Peak bone stiffness of Korean women was relatively lower than that of white women (94% of white women) and a rapid rise of bone stiffness was observed in those subjects 3-4 years after menarche. In adolescent females without menstruation, the bone stiffness was lower than that of adolescent girls with menstruation. The factors affecting the peak bone mass was similar to the risk factors of post menopausal osteoporosis: menstruation status, calcium intake and physical activity. The amount of calcium intake in Korean girls at the critical age (3-4 years after menarche) was lower than the RDA (requirement of daily allowance) at this age. To improve any program aimed at maximizing peak bone mass, further intensive study will be required to evaluate some other common factors affecting peak bone mass in Korean.

Urolithiasis and calcium oxalate crystal deposition diseases are still significant medical problems. In the course of nephrocalcin cDNA cloning, we have identified FKBP-12 as an inhibitory molecule of calcium oxalate crystal growth. lambdagt 11 cDNA libraries were constructed from renal carcinoma tissues and screened for nephrocalcin cDNA clones using anti-nephrocalcin antibody as a probe. Clones expressing recombinant proteins, which appeared to be antigenically cross-reactive to nephrocalcin, were isolated and their DNA sequences and inhibitory activities on the calcium oxalate crystal growth were determined. One of the clone lambdagt 11 #31-1 had a partial fragment (80 bp) of FKBP-12 cDNA as an insert. Therefore, a full-length FKBP-12 cDNA was PCR-cloned from the lambdagt 11 renal carcinoma cDNA library and was subcloned into an expression vector. The resultant recombinant FKBP-12 exhibited an inhibitory activity on the calcium oxalate crystal growth (Kd=10(-7) M). Physiological effect of the extracellular FKBP-12 was investigated in terms of macrophage activation and proinflammatory cytokine gene induction. Extracellular FKBP-12 failed to activate macrophages even at high concentrations. FKBP-12 seems an anti-stone molecule for the oxalate crystal deposition disease and recurrent stone diseases.

The fibromatosis is a broad group of benign fibrous tissue proliferations of similar microscopic appearance that are intermediate in their biological behavior between benign fibrous lesions and fibrosarcoma. Although various series have been reported of abdominal wall and extra-abdominal desmoid tumors, intra-abdominal desoids are extremely rare. We experienced a case with mesenteric fibroma-tosis occuring in a 30 year-old male. He was admitted to the Kangbuk Samsung hospital complaining of right lower quadrant abdominal mass and abdominal bloating sense. Utrasonography and computed tomography of the abdomen showed a solid mass in the left abdomen surrounded by loops of small bowel. At explorative laparotomy, there was a hard, well circumscribed round mass (25 X 15 X 12 cm) in the mesentery of the terminal ilem. After the tumor was dissected from the retro-peritoneum and surrounding tissues, segmental re- section of ileum with end-to-end anastomosis was performed. On the histopathologic examination, it was confirmed as mesenteric fibromatosis. A brief review of the literature on mesentery fibromatosis was done.

MIN GLASSES is specially manufactured in order to enhance satisfaction of wearer and therefore increase the effectiveness of treatment of an amblyopia and a diplopia. One of the lens is specially grounded and coated to blur vision. Cosmetically, the eye appears to wear regular glasses through the blur lens. We prospectively studied 58 amblyopic children and 10 diplopic adults. Each patient was treated with MIN GLASSES for cosmetic problems. We checked linear visual acuity of pre- and post-treatment. Questionnaires were given to the patients and parents regarding cosmetic satisfaction with treatment. In amblyopic children. 44 patients(75.9%) showed visual acuity improvement of 1.61 +/- 1.50 lines by Han's visual acuity chart. Patient compliance was 87.9%(51 patients) with patient satisfaction based on a questionnaire response. Parents were 87.9%(51 parents) positive response. In diplopic adults, 10 patients(100%) were positive response with satisfaction and demonstrated to be free of symptom of diplopia. MIN GLASSES is effective in high compliance satisfaction of amblyopia and diplopia, and improvement of visual acuity of amblyopia.
