To measure the birth registration rate and the validity of birth registration data in rural area, all of the 4,014 married women under 49 years of age who had not been sterilized in Gunwee county of Kyungpook province were followed by Myun health workers for 2 years from April 1, 1985 to March 31, 1987 and 766 births were detected. All of the birth registration records of Myun offices were reviewed on September 30, 1987 and 944 births which occurred within the above mentioned period were found. Actual birth date obtained by follow-up study were compared with the birth date on registration card. Among 766 births detected by follow-up study,576 births(75.2%) which were reported within 6 months after birth were ascertained on the official registration records and 96 births(12.5%) were not found on the records although mother stated that the birth was registered. The registration rate within legal due date was 61.3% among 576 births detected by follow-up study and also ascertained on the official records. The registration rate within legal due date was lower in mothers under 20 years of age and above 35 years and in mothers who had only primary education. It was decreased as the birth order increased. The registration rate was higher in births occurred from October to March than births occurred from April to September. All of the births of 7 neonatal deaths were not reported. The registered birth date was consistent with the actual birth date in 78.0%. Birth date on record was earlier than the actual birth date in 6.8% and later in 15.3%. The consistency rate was lower in mothers above 35 years of age(54.5%), and in infants of 4th birth order and above(56.3%). The rate was increased as the maternal education level increased. The rate of boys was higher than that of girls. A higher percentage(17.4%) of infants born in March was registered with earlier date than the actual birth date and most of these registered birth dates were lunar calendar date. This might be related with the age for entering the primary school. The study findings revealed that the birth registration rate within legal due date and accuracy of report have been increased in recent years, but the infant mortality rate derived from the birth registration seems to be very inaccurate. It is suggested to let the medical personnel who delivered the baby report the birth by mail directly to the current address of parent while infants delivered at home without professional attendant may comply with the present registration system.

This study was performed in rats to find the minimum dose of melatonin that can effectively prevent the formation of postoperative intraperitoneal adhesions. Forty-two Sprague Dawley male rats were divided into six groups consisting of 7 rats, respectively. After celiotomy, five abrasions of $0.5{\times}1cm$ area were made on the antimesenteric serosal surface of the colon with a scalpel blade. The abdominal cavity was filled with 1 ml of solution containing 1 mg/kg(Mel 1), 3 mg/kg(Mel 3), 10 mg/kg(Mel 10), 30 mg/kg(Mel 30) and 5% ethanol solution(sham) through the catheter, using a sterile syringe before abdominal closure. Control group was given no adjuvant. The locations and values of adhesion were assessed through the second operation on the 14th day after the first operation. The adhesions were located on serosa to mesentery(54 of 210, 25.7%), serosa to serosa(44 of 210, 21%), serosa to omentum (12 of 210, 5.7%) and serosa to parietal peritoneum(0 of 210, 0%). The incidences of adhesion in Control, Sham, Mel 1, Mel 3, Mel 10 and Mel 30 were 68.6%, 91.4%, 57.1%, 60.1%, 17.1% and 20%, respectively. The values of adhesion separation in Mel 10 and Mel 30 group were lower than those in other groups. However, there was no significant(p<0.05) between Mel 10 and Mel 30 group. This study showed that 10 mg/kg of melatonin were effective in reducing the intraperitoneal adhesion.

Background: Investigation of the change of ventricular function and mitral regurgitation after surgical repair of patient with anomalous origin of left coronary artery from the pulmonary artery (ALCAPA) is key issue for the better surgical outcome. Material and Method: From April 1986 to July 2002, 12 patients presented with ALCAPA. The median age at repair was 4 months. Surgical methods included left coronary artery transfer to the aorta (10), Takeuchi procedure (1), saphenous vein free graft bypass (1). Mitral valve was repaired in 1. Result: There were 2 hospital death $(16.7\%)$. The mean follow-up period was $7.1\pm4.1$ years (range, 7 months to 13 years). Four patients required postoperative circulatory assist for $2.2\pm1.1$ days and one needed left ventricular assist device (LVAD) for 1day. Postoperative echocardiography demonstrated significant improvements in mean fractional shortening $(33.4\pm9.1\%\;vs\;17.7\pm9.6\%,\;n=10,\;p<0.05);$ left ventricular end diastolic dimension $(33.4\pm7.3\;mm\;vs\;44.8\pm7.0\;mm,\;n=10,\;p<0.05)$ and systolic dimension $(22.2\pm7.5\;mm\;vs\;33.4\pm7.9\;mm,\;n=10,\;p<0.05)$. Severities of mitral regurgitation decreased in all survivors at 1st and 4th year follow-up echocardiography. There were 2 reoperation due to residual MR and right ventricular outflow obstruction (Takeuchi case). Conclusion: Anatomic repair of anomalous left coronary artery from the pulmonary artery offered an excellent surgical results, especially in terms of the recovery of left ventricle function and mitral regurgitation. However, preoperative indications for mitral procedure is to be evaluated.

This study was performed to evaluate the influence of composting process with an intermittent aeration on the variation of rhizosphere soil temperature, $CO_2$ and $NH_3$ release, and the growth reponse of tomato plantlet in traditional and composting greenhouse. As the temperature of composting materials increased, rhizosphere soil temperature in 30cm depth rose up to $32^{\circ}C$ at one week after introduction. This was $18^{\circ}C$ higher than that of traditional greenhouse. After 20 days of active composting, temperature of rhizosphere soil started to decrease and remained constant at $23^{\circ}C$ after 35 days. For the traditional greenhouse, the averaged temperature ranged at $14{\sim}15^{\circ}C$. This results showed that composting greenhouse had the greater effect on increasing the underground temperature. Average value of evoluted $CO_2$ from the composting greenhouse for 70 days was $782{\sim}1154ppm$. This was $1.7{\sim}2.6$ times higher than that of the traditional greenhouse with an average of $440{\sim}462ppm$. $NH_3$ release was highest during $2{\sim}10$ days in intermittent aerated composting and reached to 134 ppm maximum on the 5th day, then decreased rapidly, and maintained at $3{\sim}4ppm$ after 17 days. Increased photosynthesis due to the $CO_2$ gas and a favorable rhizosphere environment due to the increased underground temperature resulted in improved growth, yield, and Brix degree of tomato fruit.

This study was conducted to evaluate the changes in barley yield some physico-chemical properties of soils affected by annual application of N.P.K and N.P.K+silicate fertilizer 250kg/10a and N.P.K+compost 1,000kg/10a to the silty clay loam upland soil during the 18 years from 1975 to 1992. The results obtained are as follows. 1. Barley yield of the 18th year increased by 17~18% in the treatments of N.P.K+compost annually applied in comparison with N.P.K treated plot. So, simillar effect was recognized between the silicate fertilizer and the compost treatment plot. 2. The amount of nutrient's uptake by barley plant at the harvesting stage in the treats of N.P.K+silicate fertilizer and N.P.K+compost annually applied increased by 6~8% in comparison with N.P.K treated plot. Fertilizer's efficiency remarkably increased with $P_2O_5$, and $K_2O$ in the treats of N.P.K+silicate fertilizer and N.P.K+compost annualy applied comparing to N.P.K treated Plot. 3. According to soil analysis after experiment, the N.P.K+silicate fertilizer and N.P.K+compost annually applied plot were increased in soil pH, OM, available $P_2O_5$ exchangable cations and soluble $SiO_2$ content, but the content of $NO_3$-N was low. 4. Average yield of barley for 18 years increased by 22% in the treat of N.P.K+silicate fertilizer 250kg/10a annually applied plot and by 31% in the treat of N.P.K+compost 1,000kg/10a annually applied plot in comparison with N.P.K treated plot.

Between January 1992 and February 1995, 36 patients with mitral regurgitation were treated by a mitral repair There wert nineteen men and seventeen women whose mean age was 41.8 years, ranged from 10 to 71. Seventeenth patients had dystrophic change of mitral valve, twelve patients had rheumatic change of mitral valve, second patients had infective change of mitral valve and another fifth patients had functional change of mitral valve. Operation proced res were suture annuloplasty (35 cases), resection of leaflet (25 cases), chordal shortening(9 cases) and commisurotomy(1 cases). These procedures were combined in most patients. Two third of the patients were in New York Heart Association class III or IV and four fifth of the patients were in mitral regurgitation grade III or IV by doppler echocardiogram. After mitral valve repair, the patients were improved hemodynamic, echocardiographic data and functional class. Intraoperative TEE had been used in all most patients after weaning of bypass. If there remained MR more than grade 2, the valve was re-repaired or replacement. There were no operative death. The late mortality was 5.5% and cause of death was congestive heart failure. Patients have been followed up from 3 to 40 months, mean 15. Second patients underwant reoperation due to recurred mitral regurgitation, 4 and 19 days after the operation. During reoperation, we found that the repair suture was disrupted in both patients. Th s expierence demonstrated that intraoperative TEE is accurate and predictable and excellent immediate and mid-term results have been achieved by mitral valve repair.

Background: The histomorphological properties of the left anterior desecending artery (LAD), the left internal thoracic arteries (LITA), the radial arteries (RA) and the intercostal arteries (ICA) were studied for their use as a conduit for coronary artery bypass grafting (CABG), and we compared them with each other. Material and Method: All the vessels were harvested from nineteen cadavers (17 males and 2 females). The mid-portion of the LAD, the mid-portion of the LITA, the distal RA and the mid-portion of the 5th ICA were obtained. All of them were stained with hematoxylin-eosin and with Van Gieson's elastin stain. The morphological characteristics were examined and the thicknesses of the intima and media (I/M ratio: the intima to media ratio) were compared using one-way ANOVA tests. Result: The mean age of the cadavers was $61.5{\pm}9.6$ years. The LITA and ICA were elastic arteries, and the LAD and RA were muscular arteries. The I/M ratio showed statistically significant differences: $0.07{\pm}0.03$ in the LITA, $0.16{\pm}0.11$ in the ICA, $0.45{\pm}0.29$ in the RA and $0.93{\pm}0.52$ in the LAD, respectively. Conclusion: This study showed that the degrees of intimal hyperplasia of the CA and the various conduits for CABG were different significantly. The ICA was found to have relatively favorable characteristics as a coronary by pass conduit, but its suitability for clinical use is a challenging issue.

Purpose:The aim of this study is to explore the effect of the Toll-like receptor 9 (TLR9) expressed in plasmacytoid dendritic cells (pDCs) that respond to antigen to Th2 immune deviation in allergic patients. Methods:Subjects consisted of 19 allergic patients and 17 healthy volunteers. Skin prick tests and nasal provocation tests were performed for the two groups. Peripheral blood mononuclear cells (PBMCs) were collected from subjects and analyzed for the Lineage Cocktail (CD3, CD14, CD16, CD19, CD20, CD56) (-), HLA-DR (+), and CD123 (+) using flow cytometry. In addition, we analyzed TLR9 mRNA by reverse transcriptase-polymerase chain reaction. The level of $interferon-{\alpha}$ ($IFN-{\alpha}$) of the PBMCs following stimulation with the TLR9 ligand CpG-ODN 2216 was also evaluated. Results:Analyses of CD123 (+) revealed a nearly similar distribution for the classical pDC markers in the allergic group ($0.1%{\pm}0.04%$) and in the controls ($0.25%{\pm}0.23%$). The mRNA levels of TLR9 on PBMCs were not different between the allergic group and the controls ($1.29{\pm}0.41$ vs. $1.25{\pm}0.23$, respectively). Additionally, the level of $IFN-{\alpha}$ in PBMCs exposed to stimuli of the TLR9 ligand CpG-ODN 2216 was not significantly different between the two groups ($911{\pm}829$ vs. $1,095{\pm}888pg/mL$, respectively). Conclusion:We found no evidence that TLR9-dependent immune responses in human pDCs are associated with allergic status.

Acrylamide gel electrophoretic pattern of 13 wild soybean (Glycine ussuriensis) was compared with that of G. gracilis and G. max var. Gwanggyo. Average Protein content (50%) of wild soybean was greater than that of C. gracilis (46%) and Gwanggyo (45%). Grain weight of wild soybean was one third of G. gracilis and one ninth of Gwanggyo. Electrophoresis of wild soybean protein showed total 16 different bands and three of which (Rm 0.09, 0.59 and 0.84) were specific and did not appeared in 86 var. of G. max which showed four specific bands (Rm 0.35, 0.45, 0.50 and 0.77) of total 17 bands. G. glacilis had all bands of Gwanggyo and two bands (Rm 0.53 and 0.59), one of which (Rm 0.59) was specific for wild soybean indicating that G. gracilis is middle type. Of 16 protein bands the third band (32%), the first band (28%) and the 5th band (13%) were main bands. Electrophoretic pattern could be sorted qualitatively into 4 groups, semiquantitatively into 6 groups and 2 or 4 groups depending on reference pattern by correlation or pattern similarity method. All sorting methods separated a wild soybean from Sogri mountain into a group and except that there were no similarity among methods but correlation methods seems more reasonable. Protein content was no relation with electrophoretic pattern but positively correlated with percent contribution of first band at 5% level suggesting that the first band may have a important role for protein synthesis.
