Cardiac size of 291 new-born infants was measured using the method illustated on Fig 1. Among the 291 infants,53 were asphyxiated, and asphxia was only regared from Apgar score below 6 on 1 min. and 5 min. Remaining 238infants were normal, and classified to group with lung abnormalities and without lung abnormalities on chest A-Pfilm. The results are as follows; 1. The average CTR. of normal group was 52.37(C/T1;54.89, C/T2;49.43, C/T3;49.15, C/T;55.97) 2. The average CTR. of asphxiated group was 54.91 (C/T1;57.13, C/T2;51.69, C/T3;51.94,C/T4;58.25) 3. Consequently, asphyxiated infants revealed larger cardiac size than normal infant group.

BACKGROUND AND PURPOSE: Triflusal(TR), 2-acetoxy-4-trifluoromethyl banzoic acid, is a platelet aggregation inhibitor structurally related to aspirin, proven to possess both in vitro and in vivo platelet antiaggregatoy activity. The aim of this study was to evaluate the effect of TR with different dosages on platelet function using platelet aggregation, adenosine triphosphate (ATP) secretion, and thromboxane generation after TR administration. METHODS: Twenty healthy volunteers (age 25-41years, 15 males 5 females) were randomly divided into two groups of ten subjects who were receiving one of two regimens (TR 300mg/day; TR 900mg/day) for seven days. Platelet functions including platelet aggregation by impedance methods using whole blood with ADP (5, 10uM) and collagen (1,2uM), ATP secretion and thromboxane B2 generation were determined. RESULTS: The inhibitory effect of platelet aggregation was observed in both groups. The degree of inhibitory effect was depended on the dosage of TR and the types of aggregating agent. Thromboxane B2 concentrations were significantly decreased by TR ingestion in both groups (p<0.01), but there was no differences in ATP secretion. CONCLUSIONS: This study show that TR exerts a remarkable platelet antiaggregation effect and inhibition of thromboxane synthesis in whole blood. In addition, the fact that TR does not affect ATP secretion means selective blocking of the platelet cyclooxygenase pathway.

6.Changes in Proteasome Concentrations in Whole Blood and Packed Red Blood Cell Units during Storage.
Korean Journal of Blood Transfusion 2012;23(1):20-27
BACKGROUND: Proteasomes are multi-subunit enzyme complexes present in the cytoplasm and nucleus of eukaryotic cells. Proteasomes are involved in the pathophysiological process resulting in development of many diseases. Release of proteasomes from lyzed erythrocytes has been suggested in recent reports. Accumulation of proteasomes in blood products could contribute to formation of storage lesions and have adverse effects on recipients; therefore, we conducted an analysis of changes in concentration of proteasomes in blood products during storage. METHODS: Concentrations of 20S proteasomes in supernatant of whole blood products obtained from eight healthy volunteers and in segments of 16 packed red blood cell (pRBC) units transfused to patients were measured by ELISA. Plasma samples containing several hemoglobin concentrations were prepared in order to assess the relationship between proteasome concentration and degree of hemolysis. RESULTS: Proteasome concentrations in whole blood products on day one of storage were significantly lower than those on day seven of storage and later (P<0.05). In segments of pRBC units, the proteasome concentration was 8.072+/-11.802 microg/mL (storage day: 13.8+/-4.7). Of the 32 pRBC units, two showed extremely high proteasome concentrations (36.662 and 62.798 microg/mL). Proteasome concentrations in plasma increased with increasing hemoglobin concentrations. CONCLUSION: During storage of whole blood products, except during the first seven storage days, levels of proteasome do not undergo significant change. However, hemolysis may be related to accumulation of proteasome. Further study to evaluate the effects of blood components containing high proteasome concentrations on recipients should be conducted.

We attempted to identify parasite DNA in the biliary stones of humans via PCR and DNA sequencing. Genomic DNA was isolated from each of 15 common bile duct (CBD) stones and 5 gallbladder (GB) stones. The patients who had the CBD stones suffered from cholangitis, and the patients with GB stones showed acute cholecystitis, respectively. The 28S and 18S rDNA genes were amplified successfully from 3 and/or 1 common bile duct stone samples, and then cloned and sequenced. The 28S and 18S rDNA sequences were highly conserved among isolates. Identity of the obtained 28S D1 rDNA with that of Clonorchis sinensis was higher than 97.6%, and identity of the 18S rDNA with that of other Ascarididae was 97.9%. Almost no intra-specific variations were detected in the 28S and 18S rDNA with the exception of a few nucleotide variations, i.e., substitution and deletion. These findings suggest that C. sinensis and Ascaris lumbricoides may be related with the biliary stone formation and development.

Hysterosalpingograms of 375 patients with infertility were reviewed with reference to radiological features of each pathology and a comparative study of hysterosalpingography and laparoscopy in 36 patients was presented. The results were as follows; 1. In 375 cases infertility, 191 cases (50.9%) were primary infertility and 181 cases(49.1%) were secondary infertility. 2. The peak age distribution was 26 to 30 year old group in 211 cases (56.3%),and the peak duration of infertility was less than 3 years in 256 cases (68.3%). 3. Abnormal uterine findings were 115 cases (30.7%) and there were 73 cases of filling defects, 13 cases of irregularity , 12 cases of uterineflexion, 11 cases of congenital anomaly, and 9 cases of hypoplasia among them. 4. Abnormal tubal findings were 196 cases (52.3%) and there were 103 cases of simple obstruction, 69 cases of hydrosalpinx, and 50 cases of peritubal adhesion among them. 5. Intravasation of contrast media was noted in 42 cases (11.2%). 6. In 36 cases of laparoscopy, 23 cases (63.7%) was agreed to hysterosalpingography. 7. Aothough laparoscopy was better than hysterosalpinography in external anatomy of salpinx and relationship to overay, hysterosalpingography should be important for fundamental study of infertile women because of lower failure rate, lower risk of complications,therapeutic effect, and lower cost.
