2.Assessment of Bone Age: A comparison of the Greulich Pyle Method to the Tanner Whitehouse Method.
Journal of Korean Society of Endocrinology 1998;13(2):198-204
BACKGROUND: Bone age measurements have clinical significance in estimation of growth status and prediction of final adult height. Mostly used methods of bone age measurements are Tanner Whitehouse method(TW2) and Greulich-Pyle method(OP). TW2 is known to be more accurate method in determining the bone age, compared to GP. But GP is being used more widely despite some shortcomings, because TW2 is time consuming and need special training. In this study, we observed the correlation between GP and TW2 to evaluate which bone age among three portions of hand and wrist[metacarpals and phalanges(GP1), carpal bones(GP2), distai radius and ulna (GP3)], measured by GP, was more correlated with the bone age, measured by TW2. METHODS: Left hand/wrist radiographs were taken from 100 prepubertal children with normal growth. These radiogrphs were reviewed by two pediatric endocrinologists independently. Bone ages using TW2 were measured at first, and then GP1, GP2, and GP3 were measured. These bone ages had been compared with TW2, using SAS computer program. RESULTS: The mean chronological age of 100 children was 10.0+/-2.5 years(5 years to 14.7 years range, 63 males and 37 females). The bone age by TW2 was 9.0+/- 2.6 years(2.3 to 13.6 years). The bone age by GP1, GP2, and GP3 were 8.8+/-2.5 years, 8.7+/-2.9 years, and 8.3+/-2.8 years, respectively. Bone ages by TW2 were significantly closer to the chronological age than those by GP. The Pea~rson correlation coefficients of GP1, GP2, and GP3 in eomparison to TW2 were 0,87(p=0.0001), 0.94(p=0.0001), and 0.91(p=0.0001), respectively, There are significant correlatkm between bone ages by TW2 and GP. Bone ages by GP2 and GP3 were statistically significantly different from those by TW2(P<0.01). Bone ages by GP1 has no statistical difference with that by TW2(P=0.64). CONCLUSION: TW2 method is more accurate than GP method in determining the bone age, but it needs time-consuming and laborious efforts. We suggest that the use of GP method for the metacarpals and phalanges can result in a considerable saving of time with no significant loss of accuracy and reproducibility.

3.The Clinical Study on the Tibial Shaft Fractures
The Journal of the Korean Orthopaedic Association 1979;14(3):426-434
The tibia is the most commoniy fractured of all the long bones of the body. Recently, the incidence of shaft fractured of tibia has risen as a result of rapid increase in automobile accidents, industrial accidents and other sports injuries. Fracture of the tibial shaft is extremely difficult to treat and a greater incidence of osteomyelitis, delayed union and nonunion of bone than in those of the full length of the tibia surface is throat, open fracture is more frequent in this bone than in any other major bones. Two hundred eighty patients (293 cases) of the fracture of tibial shaft were treated and managed at the Department of Orthopedic Surgery, Hanyang University Hospital from May, 1975 to December, 1977. The results were as follows: 1. The rate of fracture union was accelarated under the age of 20 years but it was slow in aged group. 2. A better prognosis (fracture union) was shown in proximal one third of the tibia than middle one third and lower one third of the tibia. 3. According to the classification of Ellis, the higher delayed and nonunion rate was shown in major severity group than moderate and minor severity group. 4. A better prognosis of the fracture type was shown in the spiral and oblique fracture than in the transverse, comminuted and segmental fractures. 5. Open fracture of the tibia united later than closed fracture, especially in positive culture sensitivity test. 6. There was a prolonged rate of union about 2 weeks in cases of associated fibula fracture. 7. The proper time of weight bearing of the shaft fracture of the tibia was helpful in fracture union. 8. A better prognosis was shown in the non-operative treatment than operative treatment, especially in PTB cast after long leg cast.

Journal of the Korean Society for Microbiology 1999;34(3):253-264
OBJECTIVE: Bacteroides fragilis, normal colonic inhabitant, is the most frequently isolated anaerobes in infected tissues, particularly in intraabdominal abscesses. In the acute infection model with abscesses, the response to B. fragilis infection is characterized by infiltration of neutrophils and macrophages. This study was designed to determine whether proinflammatory cytokines could be upregulated in peritoneal tissue of B. fragilis-infected mouse model. METHODS: After C57BL/6 mice were infected with abscess-inducing encapsulated B. fragilis, RNA was extracted from the intraperitoneal tissues. Cellular RNA was also extracted from mouse peritoneal macrophages (MPM) and human peripheral blood mononuclear cells (PBMC) after infection with B. fragilis. Expression of various cytokine mRNA was assessed using RT-PCR and standard RNA. Each cytokine protein was also measured by ELISA. RESULTS: B. fragilis-infected intraperitoneal tissues showed upregulated expression of IL-1u, IL-6 and TNFu mRNA. Expression of IL-1u and TNFu mRNA and protein was significantly higher in MPM or PBMC infected with B. fragilis than in those without infection. However, expression of IL-6 mRNA and protein was not increased in MPM or PBMC infected with B. fragilis compared with those without infection. CONCLUSION: These results suggest that the cytokines can be involved in immunopathologic reactions of the peritoneal tissue infected with B. jragilis.

For the study on the effect of retinoic acid on the formation of palatal rugae and the cleft palate, retinoic acid was administered orally 150mg/kg of body weight by gastric tube at GD 10.5 to Sprague-Dawley rats. The pregnant rats were sacrificed on GD 17.5 under ether anesthesia, and laparatomized. After removal of uterus, the number of pregnant sacs and fetuses were counted. The fetuses weighed, the MEE (medial edge epithelium) thickness measured and the mitotic figures counted after routine processing and H·E stain. All the palates were photographed, and the number of rugae & the rugal pattern analysed. TEM photographs of MEE cells were observed after routine processing. The results were as follows ; 1. Rat fetus body weight after retinoic acid treatment increased significantly compared with the control group. 2. Mitotic figures in the retinoic acid treated group increased significantly compared with control group. 3. In the retinoic acid treated group, 79.3% of fetuses had cleft palates. Among fetuses with cleft palates, complete cleft palates were 10.6%, incomplete cleft palate 89.4%. Incomplete clefts were of two types ; median type (cleft palate at the intermolar region) and soft palate type (cleft posterior to the 8th rugae). Median type was 64.6% and the soft palate type 35.4%. 4. 2.3% of the fetuses had the numerical anomaly of the palatal rugae in the control group, but that of retinoic acid treated group 87.7%. 5. 17.4% of palatal rugae of the control group was disrupted, but 100% of the retinoic acid treated group disrupted. 6. Rugal papillae were observed in the 15.1% of fetuses of the control group and 63.1% of fetuses of the retinoic acid treated group. 7. Longitudinal rugae were observed in 19% of fetuses of the retinoic acid treated group, but not in the control group. 8. In TEM photographs, cytoplasmic processes, intercellular space, and desmosomes decreased. Swelling of mitochondria & ER were also found in the retinoic acid treated groups. According to the above results, it appears that there is close relationship between palatal rugae and cleft palates, and that excess retinoic acid induces disruption of pattern and numerical variations of rat fetus palate rugae. Also retinoic acid has an inhibitory effect on the proliferation of medial edge epithelial cells of palatal shelves. The cleft palates may be induced by the above mentioned retinoic acid effects. But, the exact mechanisms of retinoic acid on cleft palate formation is not thoroughly known and should be further studied.

Korean Journal of Anesthesiology 1997;33(6):1170-1175
BACKGROUND: Better effect of antiemetic drugs can be obtained by combination of multiple antiemetic drugs that have different mechanisms of action. However, if the combined drugs have similar mechanisms of action, the incidence of side effects may be increase. This study was conducted to evaluate the ability of using combination therapy consisting of metoclopramide and dexamethasone in control of postoperative nausea and vomiting. METHODS: Sixty adult female patients undergoing major gynecological operation under the general anesthesia were randomly divided into two groups according to administered drugs. The patients received a single IV dose of metoclopramide (10 mg, Group I) or metoclopramide plus dexamethasone (10 mg 8 mg, Group II) when as operator sutured the skin wound. The incidences of nausea and vomiting were assessed during the first 12, 24, and 48 hours after recovery from anesthesia. RESULTS: There were no prominent incidences of postoperative nausea and vomiting between two groups within postoperative 12 hours. But there were significantly increased incidences of nausea and vomiting in Group I (26.7%, 13.3%) compared to Group II ( 8.0%, 3.2%) during postoperative 24 hours and 48 hours. CONCLUSIONS: Combination therapy of metoclopramide with dexamethasone seemes to have no synergic effect in control of postoperative nausea and vomiting.

Korean Journal of Clinical Pathology 1997;17(5):870-877
BACKGROUND: Several studies have demonstrated that quantitation of hepatitis B virus (HBV) DNA in sera of HBsAg-positive patients is more useful test for the assessment of infectivity and for the evaluation of disease status than previously utilized numerous serological markers and qualitative polymerase chain reaction for the detection of HBV DNA. We tried to measure serum HBV DNA using a branched DNA (bDNA) signal amplification assay, which is recently introduced and known to be a simple and nonradioisotopic method. METHODS: Total forty patients with HBsAg were randomly selected and serum HBV DNA was measured with duplication using bDNA signal amplification assay (QUANTIPLEXTM HBV DNA ASSAY, Chiron, USA). Quantitation was determined from a standard curve and expressed as HBV DNA equivalents/mL (Eq/mL; 1 Eq = 1 molecule of the primary HBV DNA standard). Serum HBeAg, aspartate aminotransferase (AST), alanine aminotransferase (ALT) , and soluble interleukin-2 receptor (sIL-2R) were compared with HBV DNA. RESULTS: Serum HBV DNA was quantitated in 13 patients (32.5%) (range 6.4x106-7.4x109 Eq/mL, mean 1.8x109 Eq/mL, CV 8.1%). All eleven patients (100%) with both HBsAg and HBeAg an4 2 of 29 patients (6.9%) with HBsAg but not with HBeAg showed measurable HBV DNA (p < 0.001). In addition, serum levels of AST, ALT, and sIL-2R were significantly higher in HBV DNA measured patients compared with those of unmeasured patients. CONCLUSIONS: Above results show that more than half the HBsAg-positive patients do not have enough HBV DNA which is measurable with boNA signal amplification assay but all of HBeAg-positive patients and some of HBeAg-negative patients do. In addition, HBV DNA quantitation might be correlated with the disease activity in HBsAg-positive patients because serum levels of AST, ALT, and sIL-2R are higher in patients measured with HBV DNA than unmeasured.
