The adult worms of cestodes, Moniezia expansa and Diphyllobothrium mansoni employed in this experiment. The worms were divided into three portions, i.e. immature , mature and gravid proglottids, and each proglottids were incubated in a certain incubation period, and the glucose uptake rate, total CO2 production rate, tissue concentration and their radioactivities were employed as previous reports(Rim et al., 1965). The glucose uptake rate by M. expansa was a mean value of 6.46+/-1.23 micromole per hour per gram of wet wt. and the rate by D. mansoni was a mean value of 18.8+/-0.8 micro-mole per hour per gram of wet wt. The higher rates were observed in the mature proglottid of M. expansa and in the immature proglottid of D. mansoni . The total CO(2) production rates by the worms averaged 14.0+/-2.37 micro-mole per hour per gram in M. expansa and 17.51+/-1.54 micro-mole per hour per gram of wet wt. The relative specific activities of respiratory CO(2)(R.S.A CO(2)) averaged 22.2+/-5.15 percent in M. expansa and 54.2+/-2.2 per cent in D. mansoni. In the both worms, the higher values were obtained in the mature proglottids. Therefore, the average value of 8.84+/-2.66 per cent of glucose utilized by M. expansa and 8.23+/-0.50 percent of glucose utilized by D. mansoni from the medium glucose was oxidized into respiratory CO(2). The tissue concentrations of glycogen were a mean of 2.21+/-0.46 percent per gram of wet wt. in M. expansa and 7.56+/-1.24 percent per gram of wet wt. in D. mansoni. The higher concentration of glycogen was observed in the gravid proglottids of M. expansa, however the gravid proglottids of D. mansoni showed lower concentration of glycogen than the other proglottids. The turnover rate of glycogen pool yielded with a mean of 0.04+/-0.01 miligram per hour per gram of wet wt. of M. expansa, whereas a mean of 1.66+/- 0.46 miligram per hour per gram wet wt. of D. mansoni. Therefore, a mean value of 2.58+/-0.93 per cent(R.G.D gly) of glucose utilized by M. expansa and 53.6+/-1.4 percent by D. mansoni was incorproated into the glycogen . These data account for that at least 11.42 per cent of the utilized glucose by M. expansa and 61.83 per cent of the utilized glucose by D. mansoni participated in furnishing the oxidation into respiratory CO2 and the synthetic process into glycogen.

Of the bronchographic findings of 408 patients, performed in our hospital for recent 5 years, 108 cases showed definite bronchial obstruction, and 61 cases of those were selected and their obstructive findings were evaluated. All that not confirmed were abandoned. For evaluation of the reliability of 9 bronchographic obstruction signs onappplying to diagnose malignant or benign pulmonary diseases, each sign was identified and applied to each of the61 confirmed cases. In addition, obstructed bronchi, distance of obstruction from the bifurcation site, and thedirection of meniscus, if peresent, were evaluated. The reuslts were follows; 1. The most frequent cause ofbronchial obstruction was lung cancer (59.0%), and that of the benign obstruction was pulmonary tuberculosis(13.1%). 2. Amputation, asymmetric narrowing, thumbprint indentation, rat-tail narrowing and encasement signs werethe most accurate signs of malignancy and were practically diagnostic ones, 3, The most frequent sign in lungcancer was sharp cut off one, but it could be seen in lung abscess and in unresolved pneumonia, too. 4. Circumferential symmetric narrowing and regular concavity with a small central profection signs were specific onesto benignancy. 5. The most frequent obstruction sign in benign lung disease was gradual tapering sign, but it alsocould be seen inbronchogenic epidermoid and alveolar cell carcinoma. 6. Of all bronchial obstructions, 55.4% occurred at lobar bronchus and 77.4% of those were caused by lung cancer. 7. 77.2% of those obstruction which located within 3 times distance of the bronchial diameter at the nearest proximal bifurcation site, were lungcancer, but 75.0% of those located at over 3 times distance were benign pulmonary diseases. 8. There were nocorrelation of the direction of the meniscus at the obstructing and in differential diagnosis between benign andmalignant pulmonary diseases.

The glucose uptake rate by plerocercoid of Diphyllobothrium sp. was a mean value of 5.35+/-0.80 micro-mole/hr/g of wet wt, and total CO(2) production rates by the plerocercoid larva averaged 7.54+/-0.73 micro-mole/hr/g of wet wt. The relative specific activity into respiratory CO(2) showed a mean value of 7.30 +/-0.90 per cent. The rate of CO(2) production derived from medium C(14)-glucose was a mean of 0.58+/-0.13 micro-mole/hr/g of wet wt. Therefore, the average value of 1.92+/-0.38 per cent of glucose utilized by the larvae from the medium C(14)-glucose was oxidized to respiratory CO(2). The tissue concentration of glycogen in plerocercoid larva was a mean of 46.28 +/-2.23 mg/g or 4.63+/-0.22 per cent/g of wet wt., and the turnover rate of glycogen pool was a mean of 0.049 +/- 0.012 %/hr or 0.010 +/- 0.003 mg/hr/g of wet wt. The average value of 2.76+/-1.00 per cent of glucose utilized by the larvae from the medium C(14)-glucose was incorporated to the glycogen. These data accounts for that only 5 per cent of the utilized glucose by the plerocercoid larvae participated in furnishing the oxidation into respiratory CO(2) and the synthetic process into glycogen.

The use of CT is most reliable in diagnosis and management of brain abscess. Authors analized 17 cases of pathologically and clinically proven brain abscess during the period of 39 months from Jan. 1978 to Mar, 1982 at National Medical Center. The results were as follows; 1. The sex ration 9 males to 8 females, and no sexdifference was seen, and the greatest number of cases were seen below the age of 30(65%). 2. The otogenicinfection was the most frequent predisposing factors(8 cases). Other predisposing factors were postoperative infection (2 cases), pulmonary infection (2 cases), and congenital heart disease(2 cases). The most common site ofinvolvement was posterior fossa(5 cases). Next was temporal lobe (4 cases), and temporoparietal lobe (3 cases). 3.Most common presenting symptoms were headache, fever, focal neurological signs, and dizziness. 4. Among the 22 brain abscesses of 17 patients, the msot frequent CT finding in precontrast scan was a low density surrounded by afaint dense or dense ring (11 cases). Next was purely low density (6 cases). Associated hydrocephalus was found in4 cases, and multiple or multiloculated abscess was seen in 4 cases. 5. In post contrast scan, brain abscessusually show complete, oval or round shaped, thin, evening righ enhancement with mild or moderate surroundingedema, but there was no specific enhancement.

The glucose uptake rate by Fasciola hepatica was a mean value of 9.62 +/- 0.54 micro-mole/hr/g, and total CO(2) production rate by the flukes averaged 24.28 +/- 4.26 micro-mole/hr/g wet wt. The relative specific activity of respiratory CO(2) showed a mean value of 79.89 +/- 1.78 per cent. The rate of CO(2) production derived from medium C(14)-glucose was a mean of 19.55 +/- 3.56 micro-mole/hr/g of we wt. Therefore, the average value of 32.72 +/- 4.8 percent of glucose utilized by the flukes from the medium C(14)-glucose was oxidized to respiratory CO(2). The tissue concentration of glycogen in F. hepatica was a mean of 38.36 +/- 2.91 mg/g or 3.84 +/- 0.29 %/g of wet wt, and the turnover rate of glycogen pool was a mean of 1.6+/-0.22 %/hr or 0.65 +/- 0.13 mg/hr/g. The average value of 37.26 +/- 3.86 per cent of glucose utilized by the fluke from the medium C(4)-glucose was incorporated to the glycogen. These data account for that approximately 70 per cent of the utilized glucose by the flukes participated in furnishing the oxidation into respiratory CO(2) and the synthetic process into glycogen.

Journal of the Korean Continence Society 2008;12(2):169-177
PUROPOSE: The bladder outlet obstruction (BOO) causes a bladder hypertrophy and/or hyperplasia with time. Heparin binding epidermal growth factor like growth factor (HB-EGF) is a potent mitogen for bladder smooth muscle cell (BMSC), causing significant cellular hypertrophy. Few studies have evaluated the effect of HB-EGF on bladder hypertrophy or hyperplasia. We studied to evaluated the effect of HB-EGF on the hypertrophy or hyperplasia of human BSMC and fibroblast. MATERIAL AND METHODS: To evaluate the change of expression of HB-EGF mRNA of human BMSC under a constant stimuli of 40cm-H20 pressure during 0, 1, 3 and 5 hours, RT-PCR was perfromed. The human BMSC and bladder fibroblasts with the addition of the recombinant HB-EGF 25ng/ml were performed 3H-thymidine and 3H-leucine incorporation assay for DNA and protein production, respectively. RESULTS: The expression of HB-EGF mRNA in BMSC under a constant stimuli of 40cm-H20 pressure was up-regulated with time (p<0.05). The optimal concentration of HB-EGF was 25ng/ml. The 3H-Lecine and 3H-thymidine activity in both human BSMC and fibroblast were significantly increased in addition of 25ng/ml of HB-EGF (p<0.05 and p<0.05, respectively). CONCLUSIONS: Constant hydrostatic pressure induces the expression of HB-EGF in human BSMC. Subsequently HB-EGF induces hypertrophy and hyperplasia of human BSMC and fibroblast in vitro. Our data support that HB-EGF is one of relevant BOO-induced growth factors.
