Purpose: We underwent this study to evaluate the diagnostic potential of I-123/I-131 metaiodobenzylguanidine (MIBG) scintigraphy alone in the initial diagnosis of pheochromocytoma, compared with biochemical test and anatomic imaging. Materials & Methods: Twenty two patients (M:F=13:9, Age: $44.3{\pm}\;19.3$ years) having the clinical evaluation due to suspicious pheochromocytoma received the biochemical test, anatomic imaging modality (CT and/or MRI) and I-123/I-131 MIBG scan for diagnosis of pheochromocytoma, prior to histopathological confirmation. MIBG scans were independently reviewed by 2 nuclear medicine physicians. Results: All patients were confirmed histopathologically by operation or biopsy (incisional or excisonal). In comparison of final diagnosis and findings of each diagnostic modality, the sensitivities of the biochemical test, anatomic imaging, and MIBG scan were 88.9%, 55.6%, and 88.9%, respectively. And the specificities of the biochemical test, anatomic imaging, and MIBG scan also were 69.2%, 69.2%, and 92.3%, respectively. MIBG scan showed one false positive (neuroblastoma) and one false negative finding. There was one patient with positive MIBG scan and negative findings of the biochemical test, anatomic imaging. Conclusion: Our data suggest that I-123/I-131 MIBG scan has higher sensitivity, specificity, positive predictive value, negative predictive value and accuracy than those of biochemical test and anatomic imaging. Thus, we expect that MIBG scan is e tectively used for initial diagnosis of pheochromocytoma alone as well as biochemical test and anatomic imaging.

Citrin deficiency (OMIN #605814) is an autosomal recessive disorder caused by the SLC25A13 gene mutation with abnormal biochemical findings, including increased serum ammonia, citrulline, arginine, galactose, serum threonine-to-serine ratio, serum pancreatic secretory trypsin inhibitor, and alpha-fetoprotein. Citrin deficiency can manifest in three ways: in newborns as neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD), in older children as failure to thrive and dyslipidemia caused by citrin deficiency (FTTDCD), and in adults as citrullinemia type 2 (CTLN2) with recurrent hyperammonemia and neuropsychiatric symptoms. We report a 35-day-old asymptomatic patient with citrin deficiency who had abnormal biochemical findings.

In order to examine the toxicity of palatinose-L (Pal-L) bioconverted from sucrose, we performed a 14-consecutive day toxicity study with male and female Sprague-Dawley (SD) rats. We recorded clinical signs of toxicity, body weight, organ weights, hematology, blood biochemical, urinalysis, histological changes in organs, such as the liver and kidneys, and clinical chemistry analysis data for all SD rats. There were no significant changes in food/water consumption, body weight, and organ weights during the experimental period. Although there were some hematologic and urinalysis alterations, these changes were not considered toxicologically significant. In addition, histopathological examination of the liver and kidneys revealed no abnormal or toxicological changes between the control and Pal-L-treated rats of both sexes. Collectively, these results suggest that Pal-L was not indicated to have any toxicity in the SD rats when it was orally administered up to a dose of 1,000 mg/kg/day for 14 days.

To evaluate the bone mineral density (BMD) and biochemical markers. We evaluated the BMD of femoral neck and lumbar spines of 998(male 568, female 430) persons who took a regular health screening in Woosuk University Hospital from September 2007 to March 2008 by dual energy bone mineral densitometry. Results of BMD are different in terms of biochemical markers. Especially aged people showed osteoporotic change progressively. Degree of osteoporosis increases with age. A steep decrease of BMD can be found in postmenopausal women who have low level of female hormone. More persistent effort is needed to find out the factors that can reduce BMD values for prevention of problems by osteoporosis. In essence, research on factors related to other biochemical markers must be studied continuously.
