FDT is known as a comfortable and convenient device, and there was no restriction in pupil size and refractive error within 7 diopters.To compare the effectiveness of secreening and N-30 mode in FDT, new field analyzer. Twenty-three POAG or ocular hypertension patients(43 eyes)were included in this study. All subjects underwent FDT screening and N-30 15 minutes apart on same day within 1 month after HFA C30-2 test. Mean age of the subjects was 49.77+/-11.61 years. Fifteen men and nine woman were included in this study. Test duration was 52.3+/-6.2 seconds with FDT screening, 5.46+/-0.32 minutes with FDT N-30, and 14.46+/-1.88 minutes with HFA C30-2.In global indexes MD and PSD of FDT N-30 were well correlated with MD, PSD, and CPSD of HFA C30-2 respectively(p<0.01). In diagnosing glaucoma, sensitivity of FDT screening and N-30 was 75% and 88%respectively, and specificity of screening and N-30 was 94%and 82%respectively. In detecting defect in each test location, sensitivity of FDT screening and N-30 was 68.6%and 81.6%respectively, and specificity of screening and N-30 was 94.5%and 83.8%respectively. FDT N-30 mode appears to be superior to FDT screening mode in screening and diagnosing glaucoma as there are high correlation with HFA C30-2, good sensitivity, and specificity inspite of longer test duration.

We obtained successful functional and esthetic results by grafting of iliac marrow-cancellous bone in 2 cases of alveolar-palatal cleft patients. Bone graft of alveolar-palatal clefts provide bony support to adjacent teeth of cleft area, prevented from relapse of orthodontic arch expansion, closure of oroantral fistula and improvement of speech problem. 1. In one case, extraction of upper right central incisor that was little bone support, alignment of rotated teeth and expansion of collapsed arch segment were done with pre-orthodontic treatment. The other case. Bone grafting was done after removal of prosthesis with no pre-orthodontic treatment. 2. After mucoperiosteal incision in cleft area, the mucosal flap of labial area, palate and nose were separation and the raised nasal mucosa was sutured for closure of oroantral fistula. Then, the iliac marrow-cancellous bones were grafted to cleft site. 3. After 6 months of operation, we had seen the new bone deposition to cleft site in dental radiograph and prosthetic treatment of missing teeth were done.

This study was performed to evaluate the relationship between biological markers of lead exposure and thyroid functions among male workers occupationally exposed to inorganic lead. 30 male workers exposed to inorganic lead at smelting and battery factories were investigated, and 30 male control workers who were not exposed to inorganic lead occupationally were chosen for this study. The data were obtained using direct interview and assessment of biological markers of lead exposure and thyroid indices. As biological markers for lead exposure, blood ZPP. blood lead, urine lead and hemoglobin were measured. As thyroid indices. TSH and FT4were determined. The results of the study were summarized as follows 1. Levels of ZPP, blood lead, and urine lead were significantly higher in lead-exposed group than in nonexposed control group(p<0.01 all). Hemoglobin level was significantly lower in lead-exposed group than in nonexposed group(p<0.01). 2. Study subjects had normal values of TSH and FT4 But TSH level was insignificantly lower in lead-exposed group than in nonexposed control group(p=0.11) and FT4 level was significantly lower in lead-exposed group than in nonexposed group(p<0.01). 3. As the result of simple regression analysis in lead-exposed group. FT4 level was negatively correlated with the amount of smoke, blood ZPP, and blood lead(p < 0.05 all). 4. In lead-exposed group, FT4 was used as a independent variable and age, the amount of smoke, blood ZPP, and blood lead were entered as a dependent variables in the model. As the result of multiple regression analysis with stepwise selection method, the amount of smoke and blood ZPP were negative predictors of FT4(p=0. 04, p=0.09, respectively). In conclusion, levels of TSH and FT4were lower in lead-exposed group than in nonexposed control group. In lead-exposed group, FT4 level was negatively correlated with amount of smoke, blood ZPP, and blood lead in simple regression analysis. To clarify this relation, further research between lead exposure and thyroid function may be required for worker with long-term lead exposure or high lead exposure.

BACKGROUND: Thromboxane A2 and endothelin-1 are the potent vasoconstrictors affecting pulmonary pathophysiology in response to whole body inflammatin following CPB. Aprotinin, as an antiiflammatory agent, may decrease the release of such vasoactive substance from pulmonary tissues, preventing pulmonary hypertension after cardiopulmonary bypass. MATERIAL AND METHOD: Ten mongrel dogs(Bwt. ac. 20kg) were subjected to cardioupulmonary bypass for 2 hours and postbypass pulmonary vascular resistance(0, 1, 2, 3 hours) were compared with prebypass level. The dogs were divided into 2 groups; control group(n-5) and aprotinin group(n=5). In the aprotinin group, aprotinin was administered as follows; 50,000 KIU/kg mixed in pump priming solution, 50,000 KIU/kg prebypass intravenous infusion over 30 minutes, 10,000 KIU/kg/hour postbypass continuous infusion. Prebypass and postbypass 0, 1, 2, 3 hour pulmonary vascular resistance were measured. At prebypass and postbypass 0, 90, 180 minutes, blood samples were obtained from pulmonary arterial and left atrial catherers for the assay of plasma thromboxane B2 a stable metabolite of thromboxane A2, and endothelin-1 concentrations. RESULT: The ratios of pustbypass over prebypass pulmonary vascular at postbypass 0, 1, 2, 3 hours were 1.28+/-0.20, 1.82+/-0.23, 1.90+/-0.19, 2.14+/-0.18 in control group, 1.58+/-0.18, 1.73+/-0.01, 1.66+/-0.10, 1.50+/-0.08 in aprotinin group ; the ratios gradually increased in control group while decreased or fluctuated after postbypass 1 hour in aprotinin group. There was statistically significant difference between control group and aprotinin group at postbypass 3 hours(P=0.014). Pulmonary arterial plasma concentration of thromboxane B2(pg/ml) at prebypass, postbypass 0, 90, 180 minutes were 346.4+/-61.9, 529.3+/-197.6, 578.3+/-255.8, 493.3+/-171.3 in control group, 323.8+/-118.0, 422.6+/-75.6, 412.3+/-59.9, 394.5+/-154.0 in aprotinin group. Left atrial concentrations were 339.3+/-89.2, 667.0+/-65.7, 731.2+/-192.7, 607.5+/-165.9 in control group, 330.0+/-111.2, 468.4+/-190.3, 425.4+/-193.6, 4.7.3+/-142.8 in aprotinin group. These results showed decrement of pulmonary thromboxane A2 generation in aprotinin group. Pulmonary arterial concentrations of endothelin-1(fmol/ml) at the same time sequence were 7.84+/-0.31, 13.2+/-0.51, 15.0+/-1.22, 16.3+/-1.73 in control group, 7.76+/-0.12, 15.3+/-0.71, 22.6+/-6.62, 14.9+/-1.11 in aprotinin group. Left atrial concentrations were 7.61+/-17.2, 57.1+/-28.4, 18.9+/-18.2, 31.5+/-20.5 in control group, 5.61+/-7.61, 37.0+/-26.2, 28.6+/-21.7, 37.8+/-30.6 in aprotinin group. These results showed that aprotinin had no effect on plasma endothelin-1 concentration after cardiopulmonary bypass. CONCLUSIONS: Administration of aprotinin during cardiopulmonary bypass could attenuate the increase in pulmonary vascular resistance after bypass. Inhibition of pulmonary thromboxane A2 generation was thought to be one of the mechanism of this effect. Aprotinin had no effect on postbypass endothelin-1 concentration.

Candida albicans cystitis is an uncommon but well described complication of modern therapeutics. The significance of systemic factors in the defense of the urinary tract against candidal infection is unknown. However, secretions from the prostate grand in men and from periurethral glands in women have been reported to be fungistatic. Conditions that predispose to candiduria include diabetes mellitus, antibiotic and corticosteroid therapy and disturbance of urine flow. Cystoscopy with bladder biopsy are necessary to rule out bladder tumor. We report a case of BPH with candidal cystitis and review the relevant literatures.

Congenital hypoplasia of the right ventricular myocardium, also known as parchment heart or Uhl's anomaly, is a rare congenital heart defect. It was first described in Oslers principles and Practice of Medicine in 1905 and reviewed by Segall We found 29 reported cases, but there was no reported case in Korea. Recently, we experienced a case of Uhls anomaly associated with patent ductus arteriosus, atrial septal defect, pulmonary atresia and tricuspid abnormality in a 3 month-old infant, which was confirmed by autopsy. We present a case with a brief review of litteratures.

The aim of the current study was to determine the clinical significance according to the subtypes of epidermal growth factor receptor (EGFR) mutations and presence of KRAS mutations in operable non-small-cell lung cancer (NSCLC). We sequenced exons 18-21 of the EGFR tyrosine kinase domain and examined mutations in codons 12 and 13 of KRAS in tissues of patients with NSCLC who had undergone surgical resection. EGFR mutations were more frequent in never-smokers than smokers (33% vs. 14%, respectively; p=0.009) and in females than in males (31% vs. 16%, respectively; p=0.036). Mutations in exon 18-19 and 20-21 were found in 10 and 22 patients, respectively. Never-smokers and broncho-alveolar cell carcinoma features were positively associated with a mutation in exon 18-19 (p=0.027 and 0.016, respectively). The five-year survival rate in patients with a mutation in exons 18-19 (100%) was higher than that in patients without such mutation (47%; p=0.021). KRAS mutations were found in 16 patients (12%) and were not related to the overall survival (p=0.742). Patients with an EGFR mutation in exons 18-19 had better survival than patients without such mutation. Subtypes of EGFR mutations may be prognostic factors in patients undergoing curative resection.
