This studies were examined and compared the immunohistochemical distribution of the two calcium -binding proteins calbindin D -28K and parvalbumin positive neurons in the brain stem and spinal cord after transection of spinal cord in rats. In this experiment, calbindin D -28K immunoreactive neurons were mainly found in many pyramidal cells distributed in the brain stem and spinal cord of rats. Calbindin D -28K neuropil labeling was strongly noted in brain stem and in spinal all segments of the spinal cord. In contrast to parvalbumin, little differences were found in distribution, size and morphology of calbindin D -28K cell body or neuropil staining in the brain stem and spinal cord. Parvalbumin immunoreactive cells were demonstrated in all lamina of the gray matter of the spinal cord. These immunoreactive cells had the most high density in the layer I and II dorsal horn and several nuclei of the ventral horn of the all segments of the spinal cord. These immunoreactive cells between the brain stem and spinal cord were quite different markedly in number, cell size and morphology The number of parvalbumin positive cells were more than twice in the brain stem and spinal cord compared to the calbindin D -28K positive cells. Calbindin D -28K and parvalbumin -immunoreactive somata were round, oval, spindle and polygonal in shape, and the positive neurons were unipolar, bipolar, multipolar and horizontal in shape. The diameters of the somata of the two positive neurons were 30 ~40 micrometer, respectively. Also dendrites of two positive neurons were densely arrayed in arborization.

On patients with disorder of hematopoiesis such as leukemia, aplastic anemia, MDS(Myelodisplastic Syndromes), removal of infectious foci prior to the BMT(Bone Marrow Transplantation) is a necessity and what is more, there is no sufficient time to control the infections because the chemotherapy for BMT should be started as soon as possible. And the transfusion should be minimized to prevent the alloimmunization. In those reasons, oral & maxillofacial surgeons are often in need of multiple extractions, and should take into consideration the possibility of complications after multiples extractions such as infection, severe bleeding because those situations can be fatal on patients with disorder of hematopoiesis. We present our experience in multiple extractions on 30 patients with disorder of hematopoiesis referred from Catholic Hematopoiesis Stem Cell transplantation Center at St. Mary's Hospital, The Catholic University of Korea.

PURPOSE: The purpose of this study was to develop in vivo dosimetries using both chromosomal aberrations and micronuclei in mice to assess biological effects of radiations. MATERIALS AND METHODS: Five each mice were irradiated with 0, 1, 2, 3, 4, 5, 10 Gy of Cs-137 gamma-rays. We scored numbers of chromosomal aberrations in metaphase spreads and numbers of micronuclei in bone marrow smears under light microscope, and obtained the dose-response relationships. We also examined the relationship between the two dose-response curves. RESULTS: The frequency of both chromosomal aberrations and micronuclei increased with dose, in a linear-quadratic manner. The delta, beta, and alpha coefficients were 0.0176, 0.0324, and 0.0567 for metaphase analysis (r=1.0, p<0.001) and 0.0019, 0.0073, and 0.0506 for micronuclei assay (r=1.0, p<0.001). The frequency of chromosomal aberrations and micronuclei in diffirent radiation doses was significantly correlated (r=0.99, p<0.01). CONCLUSION: In vivo dosimetry using either metaphase analysis or micronucleus assay was feasible in mice. These methods could be useful to evaluate biological effects of radiation.

PURPOSE: To investigate the changes in tear flow and tear filim stability in patients with long-term instillation of antiglaucoma drug. METHODS AND OBJECTS: We measured Schirmer test score and tear film break-up time (BUT) in long-term antiglaucoma drug instilling 60 patients (120eyes) who had been diagnosed with open angle glaucoma and in randomly selected 60 normal subjects (120eyes) from March 2000 to February 2001 at Chosun University Hospital. Obtained results were retrospectively analyzed with the age progression and sex of subjects, duration of instillation, number and type of drugs to find out correlations between these factors. RESULTS: Average Schirmer test score and BUT were measured considerably lower in antiglaucomat drug instilled group compared to normal-subjects group (P<0.05, student t-test). Both measurements considerably decreased as age of patients and drug instillation time increased (P<0.05, ANOVA test). But number and type of instilled drugs had no considerable correlation to the obtained results (P>0.05, ANOVA test). CONCLUSIONS: It should be predicted that the patients who had instilled antiglaucoma drug for a long time and who are also of old age may develop dry eye syndrome and eye surface problem. So special care should be taken with glaucoma treatment in such cases.

OBJECTIVE: To evaluate the accuracy of combined transvaginal ultrasound and beta-hCG discriminatory zone for diagnosing intrauterine pregnancy, abortion, and ectopic pregnancy in early abnormal pregnancy. METHODS: Initial ultrasound findings and beta-hCG level were compared with final pregnancy outcome in 164 early pregnant women who visit our hospital with vaginal bleeding or abdominal pain. The sensitivity, specificity, and predictive value by the combination of two diagnostic tools were calculated. Statistic analysis of collected data used x2 of SPSS(9.0). RESULTS: Of 90 women with normal outcome, 64(71.1%) had a gestational sac 5mm, and in 47 cases, the hCG level was above 1,800 mIU/ml. Transvaginal ultrasound was non-diagnostic in 47(28.6%) of 164 women, and especially, 43(53.1%) of 81 cases with beta-hCG levels below 1,800 mIU/ml. The portion of accurate ultrasound diagnosis was significantly higher in women above 1,800 mIU/ml (85.5%, 71 of 83 cases) compard with levels below 1,800 mIU/ml (37.0%, 30 of 81 cases) : P < 0.001; Relative Risk(RR) 2.31; CI 95%. Sensitivity of transvaginal ultrasound diagnosis of intrauterine pregnancy, abortion, and ectopic pregnancy was 90.2%, 79.3%, and 66.7% in women who presented with beta-hCG levels above 1,800 mIU/ml, and 41.0%, 23.5%, and 75% below 1,800 mIU/ml, respectively. And, negative predictive value was 83.9%, 89.7%, and 98.8% in each of intrauterine pregnancy, abortion, and ectopic pregnancy above 1,800 mIU/ml, and 64.6%, 60%, and 97.3% below 1,800 mIU/ml, respectively. CONCLUSIONS: The sensitivity, specificity, and predictive value of transvaginal ultrasound for diagnosing abnormal early pregnancy were poor except cases of ectopic pregnancy when beta-hCG levels were low than discriminatory zone. Ultrasound impressions were well related with beta-hCG levels.

This study was performed to investigate the effect of endotoxin to the CCl4-induced liver injury. Twelve Sprague-Dawley rats were intraperitoneally injected 1.6 g/kg CCl4 as control group. Another 24 rats were orally administrated 300 mg/kg of neomycin at 16 and 3 hours prior to CCl4 injection as experimental group. Twelve among them were intraperitoneally infected 1.0 mg/kg of endotoxin(E-Coli, 0111:B4, No L-2630, lipopolysaccharide, Sigma, USA) and CCl4 simultaneously for offsetting neomycin effect. The rats were sacrificed at 1, 4, 10, and 24 hours after CCl4 injection. The liver tissues from all experimental groups were observed by light and electron microscopy. The results obtained were summarized as follows: In the CCl4 only group, the hepatocytes revealed sweling of ER and mitochondria with many lipid droplet in the cytoplasm. Focal cellular necrosis was seen at the later phase. The Kupffer cells were activated and showed many cytoplasmic processes, secondary lysosomes, and vaculoles. The endothelial cells were edematous. Several neutrophils, platelets, and microthrombi were scattered in the sinusoid. In the neomycin-CCl4-endotoxin administrated group, both hepatocytic destruction and intrasinusoidal microthrombi formation were more pronounced. In the neomycin pretreated group, the hepatocytes revealed mild cellular destruction without necrosis. There is no intrasinusoidal microthrombi. According to these results, it would be concluded that the small dosage of gastrointestinal tract-derived endotoxin affects to the liver injury caused by CCl4. The synergistic effects of CCl4 and gastrointestinal tract-derived endotoxin which can not be detoxified by damaged Kupffer cells, may be more important in the pathogenesis of CCl4-induced liver injury.
