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.

Simulated three-dimensional (3D) imaging represents reformation of conventional sectional imaging data into a series of images that closely resemble the original studied structure. We tried to make 3D mucosal surface images of the sinonasal cavities, pharynx and larynx, and evaluated the feature of normal anatomy in 28 subjects. In the sinonasal cavities, 3D imaging was capable of demonstrating the inner wall of paranasal sinuses and its openings, and general status status of the nasal cavity. In the nasal cavity. In the nasopharynx, 3D imaging provided an easy concept of sectional images as 3D picture and displayed anatomic subsites and lesions comparable to that in fiberscope. In addition, 3D imaging had advantages in overcoming the technical limitations in fiberscope. In the larynx and hypopharynx, 3D imaging gave a 3D concept of the laryngeal structures and presented additive information not seen in axial iamges thus enabling access to regions beyond the scope of fiberscope. In conclusion, 3D imaging allows an easy conceptualization of transaxial CT images in complex anatomic areas and provides additional in formations undetectable in transaxial CT. We believe that the spaces of the sinonasal cavities, pharynx and larynx would be a new field of application of 3D image.

Testicular biopsy to have been utilized as a diagnostic tool in male infertility were underwent experimentally to observe the effects on the morphology and the physiology of post-biopsied testis of 17 male rabbits. Bilateral orchiectomy was done at third day, 1st week, 2nd week and 4th week after open testicular biopsy, and biopsied testes were compared with contralateral control in histopathological views. The results were summarized as follows : 1. In seminiferous tubules of sham-operated tests, there was no significant pathologic changes. 2. The inflammatory reaction was most severe at third day after biopsy and completely disappeared at 4th week. 3. Increased thickness of tunica albuginea and fibrotic reaction were observed near the biopsy site. 4. Spermatogenesis did not only decrease near the biopsy site with atrophy of the seminiferous tubules but also mildly decreased on the far area, that all began to recover at 4th week. 5. No evidence of immunologic reaction and hyperplasia of Leydig cell were demonstrated. It was suggested that testicular injury after biopsy was developed by interference of local blood flow, obstruction of seminiferous tubules and inflammatory reaction, so that could be minimized by application of open testicular biopsy only to definitively indicated cases.

In third nerve palsy, the functions in the four of the six extraocular muscles are compromised and its treatment is the most difficult problem in the paralytic strabismus. In surgical method, large recession and resection of horizontal rectus muscles, lateral rectus muscle transposition to medial rectus muscle and superior oblique muscle transposition are used for strabismus surgery on oculomotor nerve palsied eye. We compared the results of two methods of surgical correction. In three eyes, lateral muscle transpositions to medial rectus muscle were performed. On the last follow up examination (men; 6.7 months), two eyes resulted in severe hypertropia and unacceptable ocular alignment and no improvement of limited adduction. In six eyes of whom superior oblique muscle transpositions were performed, all resulted in acceptable ocular alignment, no hypertropia, and the limitations of adduction were improved markedly. Therefore, in the treatment of third nerve palsy, sperior oblique muscle transposition is more effective than lareral rectus muscle transposition to medial rectus muscle.

The preoperative diagnosis of the masked bilateral superior oblique palsy (SOP) is very diffcult, so the clinical manifestation is very important. We studied to determine diagonostic criteria of the masked bilateral SOP. Among 24 patients. who were diagnosed as unilateral SOP preoperatively, 5 patients developed postoperative masked bilateral SOP. 2 patients had been diagnosed masked bilateral SOP preoperatively. We compared 17 cases of unilateral SOP with seven cases of masked bilateral SOP about V-shift, head tilt test and the degree of excyclotorsion. The mean V-shift of the masked SOP patients was 5.3PD and that of the unilateral SOP patients was 1.5PD(p=0.09). The mean excyclotosion difference between the primary position and downgaze was 9.7 degree in masked cases and 2.6 degree in unilateral ones respectively (p=0.35). The mean difference of hyperdeviation the right versus the left tilted head position was 22PD in masked cases and 18.1PD in unilateral ones (p=0.35). The cases of excyclotorsion difference over 5 degrees between primary and downgaze were five(71%) in masked cases but none in unilateral cases(p=0.0001). So above finding may be strongly suggested as diagnosing the masked bilteral SOP.

We studied the success rate of bilateral 7mm medical rectus recession for 24 patients with large angle congenital esotropia through long-term follow-up. The success rate was 100%(24/24) at immediate postoperative period, 83.3%(20/24) at postoperative 6 months, 79.1%(19/24) at postoperative 1 year, 64.1%(9/14) at postoperative 18 months and 54.5% (6/11) at postoperative 2 years. Residual esotropia rate was 0%(0/24) at immediate postoperative period, 16.6%(4/24) at postoperative 6 months, 16..6%(4/24) at postoperative 1 year, 14.2%(2/14) at postoperative 18 months and 18.1%(2/11) at postoperative 2 years. Consecutive exotropia rate was 0%(0/24) at immediate postoperative period, 0%(0/24) at postoperative 6 months, 4.1 %(1/24) at postoperative 1 year, 21.4%(3/14) at postoperative 18 months and 27.2%(3/11) at postoperative 2 years. Residual esotropia may develop before 6 months and consecutive exotropia after 1 year postoperatively.

To evaluate characteristic CT findings of orbital pseudotumor and to define differentialpoints from other pathology, the authors retrospectively reviewed CT of 19 patients who were prooen to have orbital pseudotumor by clinical course and, in some cases, biopsy. A variety of CT findings including extraocular muscle thickening(11 cases), streaky infiltration of retroorbital fat(11 cases), mass formation(10 cases), optic nerve thickening (6 cases), conjunctival thickening (5 cases), scleral thickening(4cases), enlarged lacrimal gland(4 cases) and destruction of orbital bone (2 cases) were observed. Thickening of the anterior portion and irregular margin were characteristic findings of extraocular muscle and optic nerve lesions. Mass formation predominantly occurs in the anterior portion of the orbit. In most cases more than two orbital structures are involved by lesion.
