Biliary atresia is a surgical disease of infancy with a very poor prognosis usually attributed to the rarity of surgically correctable case. This paper presents a case of incorrectable type of biliary atresia 50 days old Direan female infant who were subjected to the Modified Kasai Operation She had shown good bile excretion after surgery but developed recurrent fever, severe hypocalcemia and roentgenographically prover rickets during the follow up periods. She died 7 months after the operation.

OBJECTIVE: This study was proposed to evaluate the electrophysiologic changes in central motor conduction and in silent period (SP) after paraspinal transcutaneous electrical stimulation near caudal area of the spinal cord. METHOD: Conditioning stimulation was applied to T12 paraspinal area for 20 minutes using interferential current therapy (80~100 Hz) in 11 healthy subjects. The amplitude and latency of central motor conduction and duration of SP were measured in motor evoked potential (MEPs) by using magnetic stimulator, before and after the conditioning stimulation. These variables were recorded in both tibialis anterior muscle, innervated from stimulated spinal area, and both abductor pollicis brevis, innervated from cervical cord not directly stimulated by electrical stimulation. RESULTS: After conditioning stimulation, the amplitudes of central motor conduction decreased (p<0.01), and the latencies did not change in both cervical and lumbar muscles in transcranial and spinal MEP studies, and the duration of SP was decreased in same manner (p<0.01). CONCLUSION: These results mean that the excitability of anterior horn cells decreases and the supraspinal inhibitory mechanism of the central motor conduction is suppressed by a certain conditioned electrical cutaneous stimulation in entire spinal cord.

FISH is suggested as a possible method to detect the numerical and structural abnormalities of chromosomes in interphase nucleus. We performed this study to discuss the clinical usefulness of FISH in uncultured amniocytes and to set up the cut-off value for further study. We collected amniotic fluid samples from patients whose chromosome studies were recommended due to screen positive for Down and Edword syndrome in triple marker test using maternal serum. The centromeric probe for chromosome 18 and the locus-specific probe for chromosome 21 were used and the results were compared to their karyotypes. We could find 2 cases of trisony 21 and 2 cases of trisony 18 and the other cases represented normal karyotypes. The accuracies were 91% for disomy 18, 89% for trisomy 18, 92% for disomy 21 and 88% for trisomy 21. Therefore FISH technique is a possible method to detect the chromosomal abnormalities in uncultured amniocytes and the use of locus-specific probe for chromosome 21 would be more useful for detecting the aneuploidy of chromosome 21 than 13/21 centromeric probe.

BACKGROUND: Currently, cosmetic series (Chemotechnique Diagnostics, Sweden) is the most widely used cosmetic-related patch test in Korea. However, no studies have been conducted on how accurately it reflects the constituents of the cosmetics in Korea. OBJECTIVE: We surveyed the constituents of various cosmetics and compare with the cosmetic series, to investigate whether it is accurate in determining allergic contact dermatitis caused by cosmetics sold in Korea. METHODS: Cosmetics were classified into 11 categories and the survey was conducted on the constituents of 55 cosmetics, with 5 cosmetics in each category. The surveyed constituents were classified by chemical function and compared with the antigens of cosmetic series. RESULTS: 155 constituents were found in 55 cosmetics, and 74 (47.7%) of constituents were included as antigen. Among them, only 20 constituents (27.0%) were included in cosmetic series. A significant number of constituents, such as fragrance, vehicle and surfactant were not included. Only 41.7% of antigens in cosmetic series were found to be in the cosmetics sampled. CONCLUSION: The constituents not included in the patch test but possess antigenicity are widely used in cosmetics. Therefore, the patch test should be modified to reflect ingredients in the marketed products that may stimulate allergies.

BACKGROUND: It has long been suggested that neutrophils and their products are implicated as the central mediators of the acute lung injuries. Contrary to the dominant role of neutrophils in ARDS, many cases of ARDS has occurred in the setting of severe neutropenia without pufrnonary neutrophil infiltration. Therefore it is certain that effector cell(s) other than neutrophil play an important role in the pathogenesis of ARDS. This experiment was performed to define the mechanism of ARDS in the setting of neutiopenia, 1) by comparing the severity of endotoxin-induced lung injury, 2) by measurement of hydrogen peroxide production and cytokine concentration in the bronchoalveolar lavage cells and fluids obtained from different rats with and without cyclophosphamide-pretreatment. METHOD: The male Sprague-Dawleys were divided into the normal control (NC)-, endotoxin (ETX)-, and cyclophosphamide (CPA)-group in which neutropenia was induced by injecting cyclophosphamide intraperitoneally. Acute lung injury was evoked by injecting lipopolysaccharide (LPS) into a tail vein. The bronchoalveolar lavage (BAL) was performed at 3 and 6 hour after administration of LPS to measure the change of cell counts and concentrations of protein and cytokines, tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6). Hydrogen peroxide (HPO) production from BAL cel]s was measured at 6 hour after LPS administration by phenol red microassay with and without zymosan stimulation. RESULTS: The results were as follows. A change of leukocyte counts in the peripheral blood after treatment with CPA More than 95% of total leukocytes and neutrophils were reduced after CPA administration, resulting in severe neutropenia. A change of BAL cells In the ETX-group, the number of total cells (p<0.01) and of macrophage and neutrophll (p<0.05) were increased at 3 and 6 hour after LPS administration compared to those of NC- group. In the CPA-group, the number of total leukocyte and macrophage were not changed after LPS administration, but neutrophil counts were significantly reduced and jt took part in less than 0.1% of total BAL cells (p<0.01 vs NC-group). BAL cells in this group were almost all macrophages (99.7%). A change of protein concentration in the BALF In the ETX-group, protein concentration was increased at 3 hour and was more increased at 6 hour after LPS administration (p<0.05 and <0.01 vs NC-group, respectively). In the CPA-group, it was also significantly elevated at 3 hour after LPS administration (p<0.05 vs NC-group) , but the value was statistically not different from that of ETh-group. The value measured at 6 hour after LPS administration in the CPA-group became lower than that of ETX-group (p<0.05), but showed still a higher value compared to that of NC-group (p<0.05). A change of cytokine concentration in the BALF TNF-alpha and IL-6 were elevated in the ETX- and CPA-group compared to those of NC-group at both time intervals. There was no statistical difference in the values of both cytokines between the ETX- and CPA-groups. Measurement of hydrogen peroxide production from BAL cells There was no intergroup difference of HPO production from resting cells. HPO production after incubation with opsonized zymosan was significantly elevated in all groups. The percent increment of HPO production was highest in the ETX-group (89.0%, p<0.0008 vs NC-group ), and was 42.85 in the CPA-group (p = 0.003 vs NC-group ). Conclusion Acute lung injury in the setting of neutropenia might be caused by functional activation of resident alveola r macrophages.
