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 secretary meningioma is a distinct variant of meningioma that revealed characteristic light microscopic, immunohistochemical and ultrastructural features of epithelial and secretary differentiation, which was named as a distinct subtype of meningioma by Alguacil-Garcia et al in 1986. We experienced 2 cases of secretary meningioma. One was a 53-year-old female who had suffered from sudden onset of dizziness for I day. The computerized tomography revealed a sharply marginated well enhanced mass in temporal lobe. The other was a 59-year-old female who had suffered from dizziness for 8 years. The computerized tomography revealed a well demarcated lobulated mass in petrosal ridge. In both cases, multiple hyaline inclusions were scattered in the background of meningothelial meningioma. They were PAS positive, diastase resistant, stained yellow with van Gieson, and did not stain with reticulin in contrast to Psammoma bodies. The immunohistochemistry revealed positive reaction for EMA, CEA, a-FP and cytokeratin. T'he electron microscopic study revealed interdigitation with desmosomes and abundant intracellular lumina. They were lined by numerous microvilli and filled with granular material which was composed of electron dense homogenous material, me branous material, and small membrane-bound vesicles. Microvilli were filled with electron dense material identical to the material in the lumina, and some of them were interconnected with electron dense material in the lumina. It was concluded that secretary activity of the meningothelial cells and degenerated microvilli were involved in the pathogenesis of hyaline inclusions.

To assess the correlation between the remaining serum testosterone and bone mineral density(BMD), and to determine the effect of exogenous testosterone on BMD in subjects with male hypogonadism, we evaluated the serum testosterone levels and BMDs of the femur neck, Ward's triangle and the spine(L1-4) in 20 subjects with Klinefelter's syndrome and 7 with hypogonadotropic hypogonadism before and after testosterone replacement. BMDs of the femur neck, Ward's triangle and the spine were below the age-matched normal mean at 77.8%(21/20), 74.1%(20/27) and 88.9%(24/27), respectively. There were significant differences in serum testosterone levels and the spinal BMD between the two groups and the BMD of the spine closely correlated with the serum testosterone level (R = 0.63, p < 0.001). Following a mean 11.8 +/- 4.9 months of testosterone replacement, the BMD at all sites increased significantly and the pretreatment difference in spinal BMD between the two groups disappeared. We conclude that, although testosterone may increases the bone density, it has a site-specific effect of maintaining and increasing the bone mass especially at the spine in male hypogonadism.

To investigate the pathogenesis of the duodenal ulceration produced by mepirizole (1-(4-methoxy-6-methyl-2-pyrimidinyl)-3-methyl-5-methoxypyrazole) in rat, the effects of various concentraion and sorts of antiulcer drugs and truncal vagotomy on the mepirizole (200 mg/kg of body weight) induced duodenal ulcers were observed morphologically, and after mepirizole administration (200 mg/kg), amount and acidity of gastric jucie were measured sequently. The results were as follows: 1) In the control group of fasting for 24 hours after mepirizole administration only, duodenal ulcers were developed in all animals with 21.5+/-5.8 mm2 of ulcer index, perforation rate was 15%, and mortality rate was 0%. But lesions of the stomach were hemorrhagic and erosive with erosion index of 3.8+/-1.6 mm2. 2) The antiulcer drugs were significantly inhibited duodenal ulceration and gastric erosion produced by mepirizole although the inhibition effects were different. 3) After truncal vagotomy, duodenal ulcer and gastric erosion induced by mepirizole were also significantly inhibited. 4) On the gastric analysis, decrease of amount, increase of acidity, and decrease of concentration of gastric juice were observed after administration of mepirizole compared with nontreated normal group. Above findings suggest that the pathogenesis of the duodenal ulceration by mepirizole is the action of gastric acid on the duodenal mucosa with breakdown of defence mechanisms of the duodenum.

Intracranial hemorrhage is the most common neuropathologic finding in premature infants. But in full-term infants, it is less common and rarely causes death. We found out intracranial hemorrhages in 21 full-term neonates by real-time neurosonography and concluded as followings. 1) Among 21 neonates, 17 infants were male and 4 infants were female. 2) In 11 (52.3%) infants the hemorrhage was detected within 7 days after birth. 3) The intracranial hemorrhage was not related with delivery type nor Apgar score. 4) In 13 cases (61.9%) the hemorrhage was in the subependymal germinal matrix and the degree was Grade I. 5) Precipitating or associated factors were asphyxia, pneumonia, ventilator care, RDS and congenital heart disease. 6) Symptoms and signs were seizure, apnea, lethargy, cyanosis, jaundice, anemia or bulging fontanel.
