To determine the concentration and the physiologic role of metal components in blood plasma and seminal plasma in relation to male infertility, the concentrations of twelve metal components in blood plasma and seminal plasma including Na, Mg, K, Ca, Cr, Mn, Fe, Cu, Zn, Se, Cd and Pb were measured by atomic absorbance spectrophotometery or ion selective electrode analysis. Semen and blood samples were obtained from a total of 110 men including 70 male infertility patients, 20 vasectomized persons and 20 fertility proven volunteers visited to the Male Infertility Clinic of Pusan National University Hospital. The concentrations of Ca, Zn, Mg, Cr and Cd in control group were higher in seminal plasma than in blood plasma, and additionally Pb were higher in infertility group. The concentrations of all metal components revealed no significant difference according to patients' age, resident, occupation, sperm density, motility and hormone level in blood plasma, but some metal components including Ca, Mg, Cu, Mn, Cd and Pb revealed a significant difference according to each these parameters except patient's age in seminal plasma. The concentrations of Mn, Cd and Pb in the vasectomy persons were higher than in the infertility group III including testicular and epididymal factors, but not in blood plasma. We conclude that the quantitative changes of metal components in the seminal plasma may have effects on not only spermatogenesis and sperm function, but also contribute to diagnostic parameter according to organ specificity of the metal in the male reproduction.

OBJECTIVE: Rebamipide is a propionic acid derivative that has an action of the inhibition of superoxide production and removal of hydroxyl radical with the sperm incubation and cryopreservation. In the present study, to investigate whether rebamipide is useful to treat male infertility and sterility, the author observed the antioxidative effects in patient with male infertility and also examined its absorption and distribution in rat genital organ. METHODS: To measure the distribution of rebamipide in reproductive organ in the rat, carbon indicated rebamipide, 14C-OPC-12759, was orally administered to 10 Spraque-Dawley rats and its organ concentration in serum, liver, kidney, stomach, duodenum, colon, urinary bladder, seminal vesicle, epididymis and testicle were measured each time after 0.5, 1, 2, 4, 8 and 24 hours by using HPLC fluorescent method. The concentrations in semen were measured by HPLC fluorescent method in a sample of 50 infertile males who took 900 mg of rebamipide daily for 3 months. To measure the antioxidative effect and fertility rate for 3 months, each month before and after the treatment, sperm motility, vitality, the oxygen free radical formation, level of peroxidation, fetilizing capacity of semen sample which were obtained from infertile male patients by masturbation after at least 48 hours abstinence were analyzed by computer assisted semen analyzer, eosin-nigrosin stain, chemiluminescence, thiobarbituric acid method and hypo-osmotic swelling test. Simultaneously in a sample that wanted baby, both pregnancy and delivery were researched. RESULTS: The 14C-OPC-12759 concentration in the body of white rats was highest in gastrointestinal organ like stomach, smal intestine and duodenum and followed by genital organ like seminal vesicle, testis and epididymis. The rebamipide concentration in semen of infertile males was 220.77+/-327.84 ng/mL (SD) which showed a large deviation but it was higher than serum which was 126+/-76 ng/mL (SD). In the infertile males, after the treatment with rebamipide, the level of seminal reactive oxygen species (ROS) and lipid peroxidation have significantly decreased in duration of the treatment (p<0.05) and sperm vitality and fertilizing capacity except sperm motility significantly improved on post treatment of 2~3 months (p<0.05). Out of the 41 cases who hoped for pregnancy, 15 cases (36.6%) became pregnant and 12 cases had childbrith, 2 cases had miscarriage and one case is ongoing. The side effect was observed in 1 case (2%) which experienced diarrhea but it was lost spontaneously. CONCLUSIONS: We conclude from this study that rebamipide showed relatively high tendancy of absorption and excretion in the genital organ. In infertile males who had elevated ROS in semen, by specifically inhibiting the cell damage from the antioxidation, a way to preserve sperm motility, vitality and fertilizing capacity was confirmed.

A neglected Monteggia fracture can pose a significant clinical problem because of decreased range of motion of the elbow, increased cubitus valgus, progressive damage and elbow instability. Factors leading to misdiagnosis include swelling of soft tissue, overlying of bones on radiographs and lack of inclusion of the elbow on the radiograph at the ulnsr fracture. Therefore, a radiograph that includes the elbow at the ulnar fracture should be taken. A line drawn through the shaft and head of the radius into the elbow should align with the capitulum in any projection, thereby assisting in the correct diagnosis. Three cases of neglected Monteggia fracture were treated by open reduction of the radial head with repair or reconstruction of the annular ligament and osteotomy of the ulna, and satisfactory results were obtained.

The osteonectin is a sort of glycoprotein which is secreted in human tissues. The osteonectin is generally detected in number of normal or neoplastic human tissues in vivo, but hasn`t been studied the role of osteonectin in developing human teeth and odontogenic tumors. We evaluated degree of the expression of osteonectin immunohistochemically in 20 cases of developing tooth germ which growth from fetus 5 to 38 weeks, and total 51 odontogenic tumors whitch has taken from routine biopsy, such as 10 ameloblastomas, 5 cases of adenomatoid odontogenic tumors and odontomas and odontogenic fibromas, 4 cases of cementomas and calcifying epithelial odontogenic cyst and odontogenic keratocyst and dentigerous cysts and periapical cysts, and 3 cases of ameloblastic fibromas and myxomas. The results were as follows: 1. The osteonectin on the bud stage of tooth germ was strongly expressed in the epithelial dental lamina and in the outer dental epithelium on the early bell stage, and also strongly expressed in the inner dental epithelium on the late bell stage of tooth germs. 2. In ameloblastoma, the osteonectin was strongly expressed in the epithelial tumor component and especially in the acanthomatous types. 3. In both of calcifying epithelial odontogenic tumor and adenomatoid odontogenic tumors, the osteonectin was moderately expressed on the duct like spindle cells and epithelial tumor cells around calcification areas. 4. In odontogenic tumors originated from epithelial-mesenchymal tissues, the osteonectin was moderately expressed on the epithelial tumor components and in odontogenic cysts, it was expressed in ghost cells and calcification areas only. These were summaried the osteonectin may be strongly related to the developing tooth germ and odontogenic tumors and could be regulated hard tissue of human tooth in morphogenesis and involved with calcification mechanism in development odontogenic tumors.

PURPOSE: To report a case of subconjunctival foreign body migration in both eyes after collagen-containing filler injection. CASE SUMMARY: A 51-year-old female, who had been treated with collagen-containing filler in her eyelid, nose, and forehead for cosmetic complaints four months earlier, presented to our clinic with decreased visual acuity and foreign body sensation in both eyes. Slit lamp examination revealed moderate nucleosclerosis and subcapsular opacity in her crystalline lens, in addition to scattered subconjunctival foreign body infiltration in both eyes. Cataract extraction with posterior chamber lens implantation was performed, and the subconjunctival foreign body was also partially removed. Biopsy of the remaining foreign body was performed, and examination revealed foreign material and multivacuolated cells in the conjunctiva. CONCLUSIONS: Clinicians and patients should be aware of the risk of migration of collagen-containing filler inject at or near the eyelid, to the eyeball, including the conjunctiva.

PURPOSE: To report a case of endophthalmitis treated with surgical removal of the inflammatory endothelial plaque. CASE SUMMARY: A 61-year-old male was transferred to our clinic due to corneal laceration of the left eye. An emergency operation for the lacerated cornea was performed. After the operation, the patient had no specific symptoms for 8 months but then visited our clinic with sudden decreased visual acuity. On slit lamp examination, the patient had some chamber reactions. Anterior chamber reactions exacerbated after 2 months and the best corrected visual acuity was decreased from 1.0 to 0.08. An inflammatory corneal endothelial plaque and endothelial precipitates had developed. The posterior segment was not visualized due to the severe anterior chamber inflammatory reaction. No growth was observed on bacterial or fungal cultures. However, administration of eye drops and oral voriconazole were initiated based on a clinical impression suspicious of fungal infection. Despite the treatment, the infection did not respond. Voriconazole was then directly injected into the vitreous and anterior chamber. Although the patient's best corrected visual acuity slightly improved, the inflammatory reactions of the anterior chamber and vitreous did not. The inflammatory endothelial plaque on the patient's cornea was then surgically removed and the best corrected visual acuity improved to 1.0. Mycelium was detected on the KOH smear of the endothelial plaque. There were no further inflammatory reactions in the anterior chamber or vitreous after surgical removal of the endothelial plaque.

PURPOSE: The purpose of this study is to evaluate the findings of magnetic resonance imaging(MRI) of posterior fossa hemangioblastoma and usefulness of contrast enhancement with Gd-DTPA. MATERIALS AND METHODS: Seven patients with posterior fossa hemangioblastoma were studied with both pre- and post-enhanced MRI. The MR images were reviewed regarding the location, size, signal intensities of cysts and mural nodules, and their contrast enhancement pattern. RESULTS: Five tumors were located in cerebellar hemisphere, one in vermis, and one in posterior part of medulla. One patient with von HippeI-Lindau disease had a medullary hemangioblastoma with multiple pancreatic cysts. In 6 cases, the major portion of the tumor was cysts and had small mulkal nodules. The solid portion was relatiely lange in one case, cemprising half of the tumor Cysts were oval shaped and their sizes were 3--6.7cm in diameter. In five cases(71%), septations were noted within the cysts. Cysts were isointense or slightly hyperintense on Tl-weighted image and hyperintense on T2-weighted image compared with cerebrospinal fluid. Mural nodules were oval or rounded appearance in five cases and flattened appearance in two, and their size was 0.5--2.5cm in diameter. Mural nodules were isointense to gray matter. They were detected in five cases on Tl-weighted images and one case on T2-weighted images. In two cases, vascular signal void area was noted in mural nodules. On contrast-enhanced Tl-weighted images, all mural nodules were intensely enhanced. CONCLUSION: MRI proved to be a good diagnostic method to detect and characterize posterior fossa hemangioblastoma. The most common finding is Cystic posterior fossa lesion with enhancing mural nodule. Contrast enhancement is essential for specific diagnosis.

Currently, phosphodiesterase type 5 (PDE5) inhibitors are the initial treatment option for erectile dysfunction. The reported efficacy of PDE5 inhibitors is about 70%, although it is significantly lower in difficult-to-treat subpopulations. Treatment failures might be due to the severity of the underlying pathophysiology, improper use of medication, unrealistic patient expectations, difficult relationship dynamics, severe performance anxiety, and other psychological problems. Physicians must address these issues to identify true treatment failures attributable to the drugs. This article discusses factors that might affect the response to PDE5 inhibitors and develops a strategy to maximize the overall efficacy of PDE5 inhibitors in initial non-responders to PDE5 inhibitors.
