OBJECTIVE: To elucidate the correlation of nitric oxide (NO) concentrations in follicular fluid (FF) with the ovarian response as well as the age in women undergoing controlled ovarian hyperstimulation (COH). METHODS: This study was performed in 72 cycles of whom underwent COH for in vitro fertilization at infertility clinic of Changwon Hanmaeum Hospital and Pusan National University Hospital from Aug., 2003 to Dec., 2003. Each FF was collected at the oocyte retrieval and NO concentrations in FF were assessed. We analyzed the correlation of NO concentrations in FF with the ovarian response as well as the age in women undergoing COH. RESULTS: Among 72 cycles, the clinical pregnancy rate was 37.5% (27cycles). There were no significant differences in patient's age, ampules of gonadotropins used, estradiol level on the day of hCG administration, the number of oocytes retrieved, and fertilization rate between pregnant and nonpregnant groups. However, negative correlation was found between the follicular size and NO concentrations in FF. No significant correlation was found between age and NO concentrations in FF. Comparing NO concentrations in FF between pregnant and nonpregnant women by age, NO concentrations in FF were higher at nonpregnant women, significantly those of them more than 40 years old. CONCLUSION: These results suggest that NO concentrations in FF cannot be a marker for the ovarian response, and have no correlation with all parameters of COH including patients' age with exception for the follicular size.

The metal ceramic crown is currently the most popular complete veneer restoration in dentistry, but in many cases, the metal cervical collar at the facial margin is unesthetic and unacceptable. Facial porcelain margin has been used in place of it. But this dose not solve the problems, such as dark gingival discoloration and cervical opaque reflection of porcelain veneer. Recently, metal copings which were designed to terminate its labio-cervical end on the axial walls coronal to the shoulder have been clinically used to solve the esthetic problem of metal ceramic crown. But in this design, porcelain veneer of labio-cervical area which is not supported by metal may not be able to resist the stress during cementation and mastication. The purpose of this study was to evaluate fracture strength and fractured appearance of crowns according to different coping designs. A resin maxillary left central incisor analogue was prepared for a metal ceramic crown, and metal dies were made with duplication mold. Metal copings were made and assigned to one of four groups based on facial framework designs: group 1, coping with 0.5mm metal collar; group 2, metal extended to the shoulder; group 3, metal extended to 1 mm coronal to the shoulder; group 4, metal extended to 2mm coronal to the shoulder. Copings and crowns were adjusted to be same size and thickness, and cemented to metal dies with zinc phosphate cement by finger pressure. Fracture strength was measured with Instron Universal Testing Machine. Metaldies were anchored in Three-way-vice at 3mm below finish line and at 130degree inclined to the lone axis of the crown. Load was directed lingually at 2mm below midincisal edge. Load value at initial crack and at catastrophic fracture was recorded. The results obtained were as follows: 1. Fracture strength values at initial crack were higher in groups 1, 2 than in groups 3, 4 but this difference was not statistically significant(P<0.05). 2. Conventional metal collared crown had greater catastrophic fracture strength than any other collarless crowns. 3. The greater the labial metal coping reduction, the lower the catastrophic fracture strength of crowns but when more than 1mm of labial metal reduction was done, the difference in strengths was not statistically significant(p<0.05). 4. The strongest collarless coping design was group 2.

In the condition of diabetic retinopathy, the vascular changes are localized primarily in the retinal capillaries and are presumed to promote angiogenesis. To investigate the change of retinal blood flow velocities and morphological parameters in diabetic retinopathy, we measured perifoveal capillary blood velocities(v) and the size of foveal avascular zones(FAZ). Thirteen patients with diabetic maculopathy and nine healthy volunteers were included in this study. The scanning laser technique in conjunction with an image analysing system were used to assess the morphological and hemodynamic changes in diabetic retinopathy. Diabetic maculopathy group showed a slower capillary blood velocity than normal group(2.44+/-0.39mm/sec vs2.75+/-0.61 mm/sec, p>0.18). The foveal avascular zone was significantly larger in diabetic maculopathy group than in normal group(313.5+/-64.6micrometervs. 238.9+/-93.8micrometer, p<0.05). This results indicate that the retinal microcirculation is altered in diabetic patients compared with healthy subjects. These alterations may be due to the change of the capillary wall and blood viscosity in diabetic patients. The determination of these parameters can be utilized in monitoring the progress of diabetic maculopathy.

STUDY DESIGN: A case report is presented of a symptomatic sacral perineural cyst with lumbar disc herniation that has reported a few case in the literature. We report the case of symptomatic perineural cyst with lumbar disc herniation. SUMMARY OF LITERATURE REVIEW: Symptomatic sacral perineural cyst is rare and some cases of sacral perineural cyst associated with disc herniation were reported. But it is not well known that the correlation between clinical symptoms caused by mass itself and concomittant lumbar disc herniation. METHODS: A 34-year-old male presented with low back pain, both leg dysesthesia and bilateral radiating pain. Clincal sign and symptom, physical examination, diagnostic imaging studies including MRI, myelography and pathologic findings of surgical specimens were evaluated. RESULTS: After the decompressive partial laminectomy and discectomy, the patient who had diapnosed with herniated nucleus pulposus of L4-5 and L5-S1 complained residual both leg paesthesia and hypoesthesia. Patient's clinical symptom was correlated with sacral perineural cyst. So we removed the cyst. Postoperatively neurologic symptoms and signs were completely relieved. Pathologically, Sacral perineural cyst composed of meningoepithelial cell and neural tissue within cystic wall were confirmed. CONCLUSION: We could find that sacral perineural cyst sufficiently evoked a clinical symptom. So, careful observation was needed in that case of sacral perineural cyst associated with disc herniation.

Acral persistent papular mucinosis is a subtype of the localized papular mucinosis. Clinically, ivory to flesh-colored papules develop exclusively on the back of the hands, the extensor surface of the wrists, and occasionally the distal forearms. Histologically, mucin accumulates in the upper reticular dermis, typically sparing a subepidermal zone and fibroblasts are not increased in number. On experiencing a case of numerous papules on both hands and forearms of a fifty year-old woman, we present it as acral persistent papular mucinosis.

PURPOSE: The globe luxation is a rare phenomenon in which there is a forward displacement of the eye ball so that the eye lids spasmodically close behind it. In Korea, no case has been reported. The authors experienced a case of globe luxation by laceration of the conjunctiva with trauma. METHODS: The authors experienced a case of globe luxation in 64-year-old male who had crushed with infantile marry-go-round handle and complained proptosis and ocular pain. Ocular examination revealed best corrected visual acuity of right eye 0.1, IOP 44mmHg, conjunctival hyperemia and laceration, extraocular muscle limitation in all direction. Exophthalmometer shows right eye 23mm, left eye 19mm. Orbital CT yielded proptosis and globe luxation without avulsion of internal and external rectus muscle and optic nerve. RESULTS: After the lateral canthotomy, we successfully treated with the corticosteroid therapy without visual impairment or eyeball movement disorder. we report a case of globe luxation with the review of literature.
