A clinical study was made on the 28 cases underwent prostatectomy during the 5 year-period from 1964 to 1968. The results are summarized as follows: 1. The patient underwent prostatectomy revealed increasing tendency in incidence, residual urine in average and being usually in the age range between 60 and 70 years. 2. The degree of prostatic enlargement was mostly grade 11 on rectal palpation and the removed prostate was 49. 3gm. in average weight. 3. Blood loss attributable to the operative manipulation was 1143 cc. in average. The patients underwent prostatectomy were discharged on the average 21.3 days postoperatively in which postoperative indwelling catheter was left in place for 15.3 days in average. 4. Postoperatively the convalescence was uneventful and the residual urine was disappeared or decreased markedly. 5. In the patients underwent prostatectomy via retropubic approach operative blood loss was mild and postoperative duration of indwelling catheterization was short as compared to that via the suprapubic approach. 6. No serious complication other than epididymitis developed in a few patients was observed postoperatively. 7. Suprapubic prostatectomy was found to be suitable for the patient with marked prostatic enlargement while the retropubic one yielded less tissue damage and somewhat rapid postoperative convalescence as compared to the former.

57 cases of portal vein thrombosis detected by ultrasonography were analized. The results were as follows: 1.Most common cause was hepatocellular carcinoma, showing 49 out of 57 cases(86%). 2. Sonographic findings revealedechogenic thrombus in the dilated portal vein. Echogenecity of thrombus was similar to the surrounding liverparenchyma, Thrombus was mainly located in the intrahepatic branch and main portal vein. 3. The location ofthrombus in hepatocellular carcinoma was related to the location of tumor, and frequently extended to the mainportal vein(68.9%). Incidence of thrombosis in hepatocellular carcinoma revealed 49 out of 157 cases, butprospective study showed 42 out of 84 cases(50%). Thrombosis was more common in large sized ill-defined diffuseinfiltrative hepatocellular carcinoma. 4. CT(only 15 cases analyzed) findings revealed low density in the portalvein in all the cases and periportal enhancement in 10 cases on post-enhanced scan. 5. Collateral circulationswere largely detected at the porta hepatis and gallblader fossa. The detection rate was lower on theultrasonography than on the CT or angiography.

BACKGROUND: Coronary blood flow shows phasic and diastolic dominant flow pattern in normal coronary artery, which can be changed in coronary artery stenosis. We measured and analysed coronary blood flow velocity by Doppler-tipped guidewire to clarify the change of flow pattern in the proximal and distal segments of coronary narrowings. METHODS: Coronary flow velocity were measured by 0.018 or 0.014 inch Doppler-tipped guidewire in 14 paients, 17 sites(LCS 11, RCA 6) in the proximal and distal segment of coronary narrowings, during coronary angiography or coronary angioplasty after bolus intracoronary infusion of 20microg nitroglycerine. Coronary flow reserve also measured after adenosine intracoronary infusion(LCA 12gmicrog, RCA 6microg). Perent stenosis of coronary artery was measured by digital cailper in 2 different projections and averaged. RESULTS: 1) The was no significant correlation between percent stenosis and proximal distal velocity ratio(P/D) ration(r=0.56. P>0.05). 2) Average peak velocity(APV, cm/sec) and diastolic artery, respectively(p<0.01) Distal APV was significantly lower than proximal APV(p<0.01) but DSVR showed no significant difference(P>0.01). 3) Coronary flow reserve(CFR) was significantly lower in significant coronary stenotic patients compared to insignificant stenotic patients(1.8 vs 3.6, P<0.01). CONCLUSION: Coronary flow velocity measurement by Doppler dipped guidewire gave us physiologic information. We think it could be used as an important tool to assess the significance of the intermediate coronary narrowings and the effect of conorary angioplasty.

We investigated the association between the oxidative stress and the concentration of heavy metals in blood among welders. The study subjects were male manual CO2 welders(N=127) exposed to several heavy metals. The age distribution was from 20 to 63 (GM=33.7) and the geometric mean(GM) of work duration was 4.2 years. We analyze the level of blood lead, cadmium, managese and chromium which was related with the oxidative stress in the animal studies. Blood selenuim, plasma malondialdehyde (MDA), plasma alpha-tocopheol and orythrocyte superoxide dismutase (SOD) were analyzed as biological markers of the oxidative stress. The results of univariate analysis showed that the plasma MDA was significantly correlated with D-tocopherol (r=0.327) and blood selenium (r=0.313) concentration. But we could not find out any relationship between the erythrocyte SOD activities and those metal concentrations. Neither smoking nor alcohol consumption was related to the level of heavy metals and the oxidative stress biomarkers. As the results of multiple regression analysis with stepwise selection method, 1) the change of MDA level were dependant with the level of alpha-tocopherol and blood selenium concentration (R2=19.7), 2) the plasma alpha-tocopherol level was dependant with MDA and blood chromium concentration (R2=15.6), 3) in case of erythrocyte SOD activity, only the duration of work was significantly selected.

Budd-Chiari syndrome is acute or subacute occlusion of the hepatic vein and IVC, The occlusion of hepatic veins often reveals dramatic illness characterized by abdominal pain, ascites, hepatomegaly and a poor prognosis. Several recent reports have suggested that balloon dilatation may be effective in Budd-Chiari syndrome. We experienced a case of Budd-Chiari syndrome with IVC web which was successfully treated with balloon dilatation. We report the case here with a brief review of literature,

The authors experienced a case of myoglobinuria accompanied by generalized myalgia and mild fever that developed 3 hours 30 minutes after general anesthesia. Tracheal intubation was done smoothly 5 minutes after injection of thiopental sodium(275 mg) and pancuronium bromide(6 mg), and anesthesia was maintained with ethrane/N2O/O2(1.5-2%/21/21/min). There was no specific event except tachycardia and fluctuation of blood pressure throughout operation. In this case, we assume that the myoglobinuria is a presentation of the sign of an abortive type of malignant hyperthermia. However, it was not confirmed. We had good patient outeome with the supportive measures of hydration and diuresis. The patient was discharged twenty three days after operation without any complication.

Objective: To investigate the suitability of citrus-press cakes, by-products of the juice industry as a source for the whitening agents for cosmetic industry.
Methods:Ethylacetate extracts of citrus-press cakes (CCE) were examined for their anti-melanogenic potentials in terms of the inhibition of melanin production and mechanisim of melanogenesis by using Western Blot analysis with tyrosinese, tyrosinase-related protein-1 (TRP-1), TRP2, and microphthalmia-associated transcription factor (MITF) proteins. To apply the topical agents, citrus-press cakes was investigated the safety in human skin cell line. Finally flavonoid analysis of CCE was also determined by HPLC analysis.
Results: Results indicated that CCE were shown to down-regulate melanin content in a dose-dependent pattern. The CCE inhibited tyrosinase, TRP-2, and MITF expressions in a dose-dependent manner. To test the applicability of CCE to human skin, we used MTT assay to assess the cytotoxic effects of CCE on human keratinocyte HaCaT cells. The CCE exhibited low cytotoxicity at 50 μg/mL. Characterization of the citrus-press cakes for flavonoid contents using HPLC showed varied quantity of rutin, narirutin, and hesperidin.
Conclusions:Considering the anti-melanogenic activity and human safety, CCE is considered as a potential anti-melanogenic agent and may be effective for topical application for treating hyperpigmentation disorders.

In this study, we measured the activity of the erythrocyte pyrimidine 5'-nucleotidase (P5N) and urinary N-acetyl-beta-D-glucosaminidase (NAG) from 154 workers exposed to lead and 43 workers not exposed. We analyzed the correlation of the P5N activity and NAG activity with other biological exposure indices of lead such as blood lead (PbB) and zinc protoporphyrin (ZPP). The measurement was performed by using high performance liquid chromatography (HPLC), spectrophotometer and atomic absorption spectrophotometer. The results are as follows: 1. The mean value of P5N activity for workers exposed to lead was 9.50+/-.13 micromol uridine/hr/g Hb and 11.60+/-.2 micromol uridine/hr/g Hb for workers not exported. The P5N activity showed a normal distribution, but the other indices of lead showed logarithmic normal distributions. 2. The P5N activity and ZPP were decreased as PbB wag increased. But the NAG activity had no correlation with changes of PbB. 3. The correlation coefficients of the P5N activity with other biological exposure indices of lead such as PbB, ZPP, NAG activity were -0.72, -0.55, and 0.05, respectively. We speculated that the P5N activity can be used as a reliable biological exposure index of lead but NAG activity can be used as a biological management index of lead.
