Measurement of the normal pituitary gland height was performed on magnetic resonance (MR) images of 144 subjects with no known or suspected pituitary or hypothalamic diseases. Midsagittal T1 weighted images (T1WI) were used for measurement, and mean vertical height according to age and sex group was obtained. In all age groups, the pituitary height was greater in females than in meles, The group of 0-9 years in both genders showed the minimum mean pituitary height, The maximum mean height was observed in the 10-19 years age group in both genders. The height gradually decreased with increasing age after age 20 years. There was no subject with a height more than 9.0 mm in females or 8.0 mm in males. In conclusion the measurement of the normal pituitary pland height using mid sagittal MR imaging can be used for the evaluation of the pituitary gland lesions.

Background: There have been many reports on microbial contamination of antiseptics and disinfectant used in the hospitals. Mid to low level disinfectants such as chlorhexidine gluconate, quaternary ammonium, phenols and benzalkonium are reported to be the one with high risk of microbial contamination. We investigated microbial contamination of 0.05% chlorhexidine gluconate solution used in our hospital. Methods: 0,05% chlorhexidine gluconate solution and 0.05% chlorhexidine gluconate cotton balls used in the general ward and intensive care unit were randomly collected for microbial culture. Also, sterile water, 20% chlorhexidine gluconate and staining solution, which is mixed in the preparation room to make 0,05% chlorhexidine gluconate solutions, were collected for bacterial culture to evaluate the focus of microbial contamination. Results: Total of 31 chlorhexidine gluconate samples was randomly collected from general wards. intensive care unit and preparation room for microbial culture. Seven of thirteen 0.05% chlorhexidine gluconate solution and 5 of twelve 0.05% chlorhexidine soaked cotton balls kept in a canister were contaminated by Burkholderia cepacia. Sterile water used for dilution of 20% chlorhexidine gluconate to make 0.05% chlorhexidine and originally purchased 20% chlorhexidine gluconate were not contaminated by microorganism. But staining solution that is used as an additive to differentiate from other diluted disinfectants was contaminated by Bukholderia cepacia. 0.05% chlorhexidine gluconate solutions that were mixed in the preparation room were also contaminated by same organism. Source of contamination was thought to be staining solution. All the previously made chlorhexidine. solutions and staining solution were discarded. Staining solution was not used afterward. Several processes in the handling of chlorthexidine solution were corrected and no microbial contamination was found afterward. Conclusion: Diluted chlorthexidine gluconate solutions are always under a risk of microbial contamination if any of the process in the handling is overlooked. Staining solution as an additive to disinfectants should be used carefully.

A purpose of present study is to provide basic information evaluating the utility of Magnetic Resonance imaging as a biological marker estimating manganese effects to central nervous system among welders, which is conducted by comparing urinary and blood manganese concentrations and signal intensities of brain MR images between exposed group and non-exposed group, evaluating the objectivity of subjective grading estimated by correlations between Pallidal signal intensity index (P. I) and subjective grades among exposed group, and comparing the difference of signal intensities according to presence of neurologic symptoms, signs and exposure variables among the exposed group. The exposed group is composed of 11 welders complaining severe symptoms or showing neurological signs, and the non-exposed group is composed of 5 patients who admitted a hospital. Urinary manganese concentrations and signal intensities in T1-weighted MR images among exposed group were higher than those of the non-exposed group significantly, which exhibits that increased signal intensities in T1-weighted MR image represent the effect of manganese exposure. P. Is among the exposed group revealed relatively high correlations with subjective grades ( gamma =0.63, p=0.037) , which suggests the objectivity of subjective grade. Signal intensity in globus pallidus was a suitable single variable representing the effect of manganese accumulation in C.N.S system appropriately, which was verified as follows ; Increased signal intensities among the exposed group had the highest frequency and intensity in the globus pallidus, and the P.I. had a relatively high correlation coefficient ( gamma 0.62, p=0.044) with total score of subjective grades. Signal intensity with subjective grading in globus pallidus represented very high correlation gamma =0.97, p=0.00) with total score of subjective grades, and had a similar correlation coefficient with many variables. It is hard to argue that signal intensities are markers representing pathologic change in C.N.S system or can be used as a diagnostic tool for manganese intoxication, because signal intensities had no difference between the exposed group and the non-exposed group according to presence of neurological signs.

To clarity the effect of biliary obliteration on copper metabolism of rat liver and on the hepatic morphology, 0.5% cuppuric sulfate was administered intraperitoneally for 42 days following ligation of the common bile duct (CBD) of Sprague-Dawley rats. The blood copper concentration, the hepatic copper content and the accumulation patterns of copper and copper binding protein in the liver were examined and compared with those of the simple CBD ligation group and the simple copper over loaded group. CBD ligation induced marked proliferation of bile ductular structures which, after expanding the portal tracts, invaded and divided the hepatic lobules. There was, however, no excess fibosis beyond what needed to support the new ductules. The blood copper concentration and the hepatic copper content were increased by copper overload with or without CBD ligation, particularly incases with CBD ligation. Liver cell necrosis did not occur by the overloaded copper alone in rats. The hepatic copper and copper binding protein were accumulated at periportal liver cells in the group of coppe overload after CBD ligatio, whereas they began to appear at perivenular hepatocytes in the simple copper overloaded group. In conclusion, it is suggested that CBD ligation does not induce excess fibrosis or liver cirrhosis in rat as far as during our experimental period, but affect significantly on copper metabolism by intrahepatic redistribution of the copper and the copper binding proteins.

Idiopathic thrombocytopenic purpura is an uncommon illness but most common form of thrombocytopema in pregnancy. Corticosteroids, splenectomy, immunosuppressive drugs, and immunoglobulin therapy have been recommended for manaaement. The optimal method of delivery is controversial. We have experienced a case of idiopathic thrombocytopenic purpura diagnosed previously and managed with corticosteroid and vincrstine, which was followed by pregnancy, vaginal delivery and postpiirtum splenectomy.

The prevalence of dermographism in 249 Korean pregnant and puerperal women was studied using a dermographic tester. The result was summarized as follows: 1. The prevslence rate of dermographism was 8.0%(20/249). 2. The prevalence rate of dermographism was not significantly correlated with the stages of pregnancy(p>0.1). 3 There was no significant difference in the prevalence rate of dermographism between the pregnant and puerperal women(8.0%) and the control group of Korean women in the same ages(9.5%) (p>0.1).
