PURPOSE: It has been generally known that prostatic volume is increased related to aging process and changing in hormonal environment, so lower urinary tract symptoms develops. But, our experience has revealed the decrease of prostatic volume in many cases with lower urinary tract symptoms despite aging. MATERIALS AND METHODS: The numbers of patient underwent TRUS were 301 cases. Among the patients who had visited urologic outpatient clinic from march, 1993 to march, 1996, transrectal ultrasonography of prostate was applied to patient with following conditions. 1) over 8 in IPSS with or without enlarged evidence from digital rectal examination 2) enlarged evidence from digital rectal examination 3) no symptomatic relief after 2weeks therapy with alpha blocker 4) when the patient wants more evaluation. RESULTS: Decrease of prostatic volume were shown in 66cases(22%) despite lower urinary tract symptoms. CONCLUSIONS: In our experience, many patients with lower urinary tract symptoms showed decrease of prostatic volume. So, we expect that many more cases of decrease of prostatic volume can be seen among asymptomatic cases with age. Because we can guess that prostatic volume can be influenced by racial differences and dietary habit, we also believe that further evaluation and investigation of this nature is needed.

Hemophilia A is a bleeding disorder resulting from a congenital deficiency of factor VIII. The mainstay of successful hemophilia therapy for either treatment or prevention of acute hemorrage is prompt and sufficient intravenous replacement of factor VIII to hemostatic levels. One of the most serious complications of hemophilia and its therapy is the development of polyclonal antibodies to factor VIII that neutralize factor coagulant activity. APCCs is otherwise known as bypass therapy, products that bypass the requirement for factor VIII for clot formation and moderately effective in controlling bleeding in high inhibitor patients. We experienced a case of hemophilia A with high inhibitor titer in a 13 year-old boy who presented with incarcerated right inguinal hernia and a successful therapeutic effect of APCCs(Autoplex) for controlling post-operative hemorrhages.

Scute/larisa baica/ensis (SB) has been used as a folk medicine for curing ulcer, inflammation and infection. However, surprisingly little has been done to develop and exploit SB's immunomodulating, anti- inflammatory properties. Moreover, the mechanisms of SB-action on immune function had not been elucidated. The present study was undertaken to investigate the effect of 5B on immune functions, microbial growth and bacterial mutagenicity. Boiling water extract of SB was used in this experiment. The proliferation response to PHA-, Con A- or LPS-stimulation and the production of Con A-induced IL-2 and LPS-induced IL-6 of splenocytes from SB-pretreated mice were significantly higher than those of splenocytes from control mice. Daily single injection of 2 mg/mouse SB for 4 days resulted in enhancement of Arthus reaction and DTH to SRBC. And these enhancements were more prominent when SB was treated prior to SRBC- sensitization. SB did inhibit the growth of microorganisms such as C. albicans, C. neoformans, E. coli S. typhimurium and this inhibiting effect was gradually increased in proportion to the increment of SB. SB also remarkably reduced the mutagenicity of mutagens such as sodium azid and benzo[a]pyrene, but this was not certain, because it showed a killing effect on the cell survival test. When SB treated mice were i.p infected with C. albicans, the number of microorganisms in the peritoneal exudates were significantly reduced. Taken together, these results revealed that SB itself has not only multiple effects on events controlling immune responses but also anti-inflammatory properties, which may provide the rational basis for their therapeutic use as one of the biological response modifiers.

The changes of electroencephalogram(EEG) in patients with dementia are most commonly studied by analyzing power or magnitude in certain traditionally defined frequency bands. However because of the absence of on identified metric which quantifies the complex amount of information, there are many limitations in using such a linear method. According to chaos theory, irregular signals of EEG cal also result from low dimensional deterministic chaos. Chaotic nonlinear dynamics in the EEG can be studied by calculating the correlation dimension. The authors have analyzed EEG epochs from three patients with dementia of Alzheimer type and three matched control subject. The result showed that patients with dementia of Alzheimer type had significantly lower correlation dimension than non-demented controls on 12 channels. Topographic analysis showed that the correlation dimensions were significantly lower in patients with Alzheimer's disease on frontal, temporal, central, and occipital head regions. These results show that brains of patients with dementia with dementia of Alzheimer type have a decreased complexity of electrophysiological behavior. We conclude that the nonlinear analysis such as calculating correlation dimension can be a promising tool for detecting changes in the complexity of brain dynamics.

Serum Immunoglobulin (Ig)A, IgG, IgM, levels were measured in 99 coal workers' pneumoconiosis (CWP) patients and 12 healthy coal workers and 9 non-miners to compare with each group by the radiological categories, its complications and working period in coal mine. Serum were measured by nephelometry. The findings were as follows: 1) Serum IgA levels were significantly different between three groups of CWP patient, healthy coal worker and non-miner (mean+/-standard deviation: 226.4+/-87.7, 221.3+/-45.1, 170.1+/-65.7 respectively). 2) There were no significant differences of Ig levels among radiological categories of CWP. 3) There were no significant differences of Ig levels among simple pneumoconiosis and its complicated disorders. 4) The three Ig levels were slightly increased in the group of mining years less than 20 years (IgA: r=0.1869, p<0.10 IgG: r=0.2902, p<0.05 IgM: r=0.2889, p<0.05).

The authors developed a computer program for use in report printing as well as data storage and retrieval system at the surgical pathology and its efficacy was evaluated at the Department of Pathology, Seoul National University Hospital. This program used IBM PC XT and was written in DBASE III plus language. The main features of the program included an automatic coding and decoding of the diagnosis, automatic searching of the previous biopsy during gross dictation, powerful word processing function and flexibility of the program. The data storage was carried out during the typewriting of the report, so that the typist's workload became markedly reduced. Two kinds of data files wer stored in the hard disk ; the temporary file contained full informations and the permanent file contained the core data only. Searching of a specific case was performed by pathology accession number, chart number, patient's name or by SNOMED code within a second. All the cases were arranged by copied to the diskette during the daily service automatically, with which data were easily restored in case of hard disk failure. The advantages of this program using a persosnal computer were discussed with comparison to those of larger computer system. Based on the experience of 8 months usage in Seoul National University, we assume that this program gives a sufficient solution to the surgical pathology service of many institutes where a large computer system with well designed software is not available yet.

A Fourier transform infrared spectrophotometric method was described for the determination of quartz, mica(sericite) and feldspar(potassium feldspar) in respirable dust in Taebaek area. The results were as follows; 1) The concentration of minerals were determined from the intensity of absorption peak of quartz at 799 cm-1, sericite at 539 cm-1, and potassium feldspar at 648 cm-1 respectively. 2) The precision(C. V. %) for the quartz determination was 7.70+/-2.68 % from 10 to 200 microgram of quartz. 3) The precision for the sericite determination was 16.34+/-6.82 % from 30 to 500 microgram of serictite. 4) The precision for the potassium feldspar determination was 5.28+/-1.74 % from 30 to 500 microgram of potassium feldspar. 5) The concentration of respirable dust in Taebaek area was 4.90+/-3.29 mg/m3(0.4-93.7%), percent quartz was 1.80+/-4.14% (0.01-20.56%), percent sericite was 11.37+/-6.43% (0.00-29.69%), percent potassium feldspar was 8.15 % (n=7, 3.41-19.70%). 6) The difference of respirable coal dust, quartz, and sericite concentration in drilling, coal cutting, hauling and separating was significant respectively (p<0.05).
