PURPOSE: To report pathological, histochemical, ultrastructural, and spectrographic analysis of explanted hydrophilic acrylic intraocular lenses obtained from patients who had visual disturbances caused by postoperative opacification of the IOL. METHODS: Forty-three hydrophilic IOLs (ACRL-160, Ophthalmed Inc.) were explanted from 39 patients with decreased visual acuity because of opacification of the IOL itself. All explanted IOLs were examined grossly and by light microscopy. Full-thickness sagittal sections of the optics of the randomly selected 10 IOLs were stained with the von kossa method (special stains for calcium). One of these sectioned IOLs was not stained, and submitted for scanning electron microscopy and energy dispersive X-ray spectroscopy. RESULTS: Microscopic analysis revealed multiple fine, granular deposits within the lens optics and haptics, and these deposits were stained positively with the von Kossa method. They were varible in size, and unevenly distributed in the optics on the scanning electron microscopy, and energy dispersive X-ray spectroscopy of the internal substance of IOL demonstrated the presence of calcium within the deposits. CONCLUSIONS: We evaluated 43 explanted opacified ACRL-160 lenses, and have demonstrated that the opacification was caused by the presence of granular deposits within the IOL. The deposits have the component of calcium.

OBJECTIVE: To determine whether the follicle stimulating hormone(FSH) receptor gene mutation (C566T point mutation) is present in Korean women with premature ovarian failure and normal karyotype. METHODS: Genomic deoxyribonucleic acid(DNA) obtained from 40 patients with chromosomally competent premature ovarian failure and from 30 normal fertile women(control group) was amplified by polymerase chain reaction(PCR). PCR products were digested by the enzyme BsmI and polyacrylamide gel(PAG) elctrophoretic patterns of these enzyme-digested products were analyzed. The direct sequencing of PCR products was also performed. RESULTS: All patients with premature ovarian failure and 30 normal control women demonstrated homozygous, normal alleles with 51- and 27- base pairs fragments in PAG elctrophoresis. The absence of C566T point mutation in both group was confirmed by direct DNA sequencing. CONCLUSIONS: A C566T mutation in FSH receptor gene is rare in Korean women with premature ovarian failure and normal karyotype.

An increase in the dose of chemotherapy enhances the response of many experimental and clinical cancers, but the extent of chemotherapy dose escalation and repeated use is often limited by myelosuppression. The side effects of chemotherapy including bleeding and infection due to myelosuppression have resulted in delayed therapy and a reduction in the therapeutic dose, therefore it is necessary to overcome myelosuppression especially leukopenia in patients with gynecologic malignancies who recieved chemotherapy. This study is undertaken to investigate the clinical effects of rhG-CSF(recombinant human Granulocyte-colony stimulating factor) in 29 patients with gynecologic malignancy who recieved chemotherapy. It was given at a dose of 100 microgram bid/day subcutaneously until significantly increase of leukocyte count in leukopenic patient. The results showed, the rhG-CSF has significantly increased the number and function of leukocyte. The use of rhG-CSF was effective and useful to treat chemotherapy induced leukopenia and to accelerate the recovery from this complications.

Immunohistochemical changes of epidermal growth factor receptor (EGFR) and nerve growth factor receptor (NGFR) were investigated in the rat mandibular molar and incisors after submandibular sialadenectomy. In the sham operated rat, any EGFR immunoreactivity was not observed in the teeth but NGFR immunoreactivities were observed exclusively in the periodontal ligament and ameloblasts of incisor. In the sialadenectomized rat, EGFR immunoreac-tivities were observed in the odontoblasts of the mandibular first molar, periodontal ligament cells, ameloblasts of incisor and some cells of bone marrow. NGFR immunoreactivities were more intense and widely distributed in alveolar bone, periodontal ligaments and odontoblasts of the sialadenectomized rat than in the sham operated rat. Both of EGFR and NGFR immunoreactivities gradually increased in their intensities in a time-dependent manner after submandibular sialadenectomy. The results show that expression of EGFR and NGFR in the mandibular molar and incisor is enhanced by submandibular sialadenectomy. Therefore, it is suggested that EGF and NGF derived from submandibular gland may affect to the mandibular molar and incisors by direct and/or indirect mechanism.

As a result of surgical orthodontic treatment of mandibular prognathism, changes take place in the skeletal and soft orofacial components. Although some investigators had stated that permanent reduction of airway space was observed agter mandibular setback surgery, it was not clear thath this permanent reduction was sustained during long-term follow-up. The purpose of this study was to assess the changes in oropharyngeal airway space and soft tissue orofacial compoment following the mandibular setback surgery and during the follow-up period. The correlation between the changes of the oropharyngeal airway space and the changes of other soft tissue orofacial component was also assessed. The findings of this study were as follows ; 1. The ofoharyngeal airway space area fecreased following mandibular setback surgery for mandibular prognathism and continued to decrease during the follow-up period(p<0.05). 2. The pharyngeal depth at Xi point level and the 2nd cervical vertebra point level decreased agter the surgery and remained during the follow-up period(p<0.05). The decrease of these pharyngeal depth was correlated with the decrease of oropharyngeal airway space area(p<0.01). 3. The decrease of pharyngeal depth at the 3rd and 4th cervical vertebra point level was not significant after the surgery and during the follow-up period. 4. The hyoid bone moved downwasd after the surgery(p<0.05), but returned to its original position during the follow-up period. 5. The length & height of tongue and the position of epiglottis base did not change significantly(p<0.05). 6. The soft palate was displaced posteriorly after the surgery and remained to its changed position during the follow-up period(p<0.05) due to posterior displacement of tongue. The changes of soft palate were significantly correlated with the decrease of oropharyngeal airway space area(p<0.01). 7. The narrowing of oropharyngeal airway space was due to the posterior displacement of tongue above the level of epiglottis tip. The posterior displacement of tongue following mandibiular setback osteotomy remained during the follow-up period.

Multple features of occlusion have been combined by epodemiologists in attemps to objectively to determine malocclusion severity and treatment priorty. Jenny et al were developed DAI(Dental Aesthetic Index), which is an orthodontic index based on socially defined aesthetic stamdards. This stydy aimed to evaluate association between 10 occlusal componets of DAI and individual measures of skeletal morphology by use of univariate and multivariate analysis. In addition the relationship between a Dental Aeathetic Index score and skeletal mophology was evaluated. The data for this study were obtained from cephalometric radiographs and dental casts of 182 korean patients(79 men, 103 women) with permanent dentition who had been acccepted for the orthodontic treatment at Department of Orthodontics, Chonbuk National University. The results are as follows : 1. Several occusal components of DAI(missing, crowding and spacing in the incisal segment, diastema, largest anterior irregularity on upper and lower arch) were not associated with individual measures of craniofacial morphology. 2. Sagittal occlusal components of DAI were associated with anteroposterior skeletal measures. 3. The relation between vertical occlusal components of DAI and vertical skeletal measures was low magnitude. 4. A Dental Aesthetic Index, which is based on several aspects of occlusion, did not identify craniofacial morphology. We can conclude that combination of certain occlusal components of the DAI may be related with specific skeletal morphology: but, this concept could not be accepted generally.

BACKGROUND: Prolonged air leak is a common complication after thoracoscopic bullectomy. MATERIALS AND METHODS: A technique is described to minimize postoperative air leak in thoracoscopic surgery for the treatment of recurrent or persistent spontaneous pneumothorax. RESULTS: A 3.5cm utility incision is made in the anterior axillary line at the level of the third intercostal space, and blebs and bullae are stapled and sutured without excision, using standard surgical instruments and stapler. CONCLUSIONS: This technique may be useful to reduce prolonged air leak after removal of the bleb and bullous lesion, and may minimize the delayed recurrence of ipsilateral pneumothorax.

Survival rate after renal transplantation has increased by using intense immunosuppressive agents and sophisticated operative techniques were introduced but incidences of malignancy is increasing after transplantation. Renal transplanted patients undergo variable malignancy but the acute T-cell lymphoma originating in the face is relative rare. Cyclosporin A is an immunosuppressive agent with selective inhibitory effects on T lymphocytes. It is currently available to use in organ and bone marrow transplantation recipients. We report a case of acute arising T-cell lymphoma on forehead of a 56-years-old male patient. This patient received renal allograft about 15 years ago. And then for recent 3 years, he takes Cyclosporin A 15mg/day due to allograft rejection. Its pathologic finding was diffuse large T-cell type and exhibited homogenecity of the tumor. He has been followed 3 months and no relapse occurred. We report this case with a brief review of literatures.
