The chrome content of 8 Korean cements and 11 Korean bleaching detrgents was analyzed by the qualitative DPC method and the quantitative atomic absorption spectrophotometry and UV-visible spectrophotometry. In cements, there was no detectable chrome in 1 sample and the range of chrome content in other 7 samples was 1.32 5.29ppm. The qualitative result was welJ. correlated with the quantitative result. In bleaching detergents, there was no detectable chrome in 4 samples and the range of chrome content in other 7 samples was 0.0329 0.362ppm. However, the qualitative result was not correlated with the quantitative result.

BACKGROUND: Calcitonin gene-related peptide(CGRP)-containing nerve fibers are widely distributed in the skin including the area around hair follicles. OBJECTIVE: This study was undertaken to investigate the effect of CGRP on normal hair growth in vitro. METHODS: CGRP was added to isolated anagen hair follicles in Williams' E media or keratinocyte growth media(KGM). Measuring the length of hair follicles and thymidine uptake were used for hair growth parameters. RESULTS: CGRP-treated groups generally showed no significant difference of hair follicle length and thymidine uptake in both media compared to the controls. However, hair follicle length was significantly increased at a high concentration of CGRP in KGM compared to the controls. CONCLUSION: Our study suggested that CGRP may be a promoter of hair follicle growth in vitro.

To evaluate the efficacy of STIR (short tau inversio recovery) image in the diagnosis of orbital diseases, we compared the STIR images with conventional SE(spin-echo) images in 17 patients. The fat signal was reliably nulled at inversion time of approximately 160-170 msec in all cases. We analyzed all the cases in the aspects of the detection of lesion and the lesion-to-back ground contrast retrospectively. Regarding lesion, the detection rates of STIR, T1 and T2-weighted images were 89, 88 and 83% respectively. In the aspect of lesion-to-background contrast, the contrast ratios of STIR and T1, T2-weighted image were 87% and 64, 56%, respectively. In conclusion, STIR images were similar to T1-and T2-weighted images in the detection of lesion, but superior in the aspect of lesion-to-background contrast. So the STIR images may be a useful adjunct to conventional SE images for the diagnosis of orbital disease.

Diabetes insipidus(DI) of central origin is a clinical syndrome resulting from low blood levels of antidiuretic hormone secreted from the posterior lobe of the pituitary gland, which is usually caused by lesions involving the hypothalamus-neurohypophyseal axis. MR imaging can reveal absence of the posterior pituitary bright signal(PPBS)in DI. The authors reviewed four patients with intracranial germinomas who had DI due to hypothalamus involvement. All patients before radiotherapy revealed absence of PPBS on MRI. Three cases recovered from DI after radiotherapy and showed reappearance of PPBS. Another one patients who continued DI didn't show signal change of the posterior pituitary gland. Ws speculated that the reappearance of PPBS is related to clinical improvement of DI.

PURPOSE: To analyze the imaging features of brain abscess. MATERIALS AND METHODS: MR studies of nine patients with surgically verified brain abscess were retrospectively reviewed. RESULTS: The shape of abscesses were round(n=6), multilobulated(n=2) or triangular(n=1). All lesions were located in corticomedullary junction and extended into white matter. On gadolinium-DTPA enhanced images, smooth rim-like(n=6) or irregular thick enhancement(n=3) of abscess wall was noted. Budlike projection from the abscess capsule was found in 4 cases. The signal intensity of abscess capsule was either hyperintense (n=5) or isointense(n=4) relative to white matter on Tl-weighted images, and hypointense(n=6), isointense (n=2) or mixed hypo and isointense(n=l) on T2-weighted images. Satellite nodules were found in 2 cases. PNS inflammation(n=2), meningitis(n=1), ventriculitis(=2) and subdural empyema(n=1) were associated CONCLUSION: The MR features of brain abscess included characteristic intensity of abscess capsule, budlike projection from the abscess wall, moderate amount of peripheral edema, satellite nodules, and associated meningitis, ventriculitis or PNS infection. The morphology of abscess wall was not specific for the diagnosis of brain abscess.

BACKGROUND: Transepidermal water loss(TEWL) measurement is widely used in monitoring the degree of skin irritation. There have been many reports of site variation of TEWL between different body sites. However, there have been no reports concerning site variation on the different parts of the hand, which is important for the evaluation of hand eczema. OBJECTIVE: This study was done to better understand site variation of TEWL on the hands. METHODS: TEWL measurement has been performed on the mid-forearm and seven different sites of the hands in 20 normal human volunteers using an evaporimeter. RESULTS: A marked site variation has been observed and high values observed on most parts of the hands compared to forearms. CONCLUSION: Site selection should be seriously considered in any kind of study concerning TEWL measurement of hands.

Bone scan measuring bone metastasis were analysed in fifty five patients diagnosed as malignant tumor, seven were primary bone tumor and forty eight were metastatic tumor, who treated in Kyung Hee Hospital from March 1981 to January 1982. The results were as follows: l. In 55 patients, positive bone scan were found in 76.4% of the patients and positive X-ray were found in 56.4%. 2. 7 patients with primary bone tumor showed all positive bone scan, 45 patients with metastatic tumor showed positive bone in 72.9%. 3. Among the patients with metastatic tumor who no clinical symptoms, positive bone scan were found in 59.3% and positive X-ray in 26%. 4. Most common metastatic site was femur in primary bone tumor and vertebra in metastatic tumor. 5. In 48 patients of metastatic tumor, positive bone scan within negative X-ray were found in 56%, negative bone scan within positve X-ray were found in 5%. 6 The lesions showed clod area on bone scan were considered of positive finding as compared with clinical symptom and X-ray finding.
