BACKGROUND: A and B transferase are glycosyltransferase that transfer N-acetylgalactosamine and D- galactose to H antigen, respectively and lead to the expression of A and B phenotypes in ABO blood group system. Reduced or no activities of serum A and B transferase were observed in some A and B subgroup individuals. Determining the activities of serum A and B transferase can be useful in discriminating rare A and B subgroups. MATERIALS AND METHODS: ABO typing, saliva test, adsorption elution test and serum transferase assay were performed on samples from 12 individuals showing ABO discrepancy or weakened cell typing reactions which were referred to the Seoul National University Hospital to confirm their ABO blood types. Serum transferase activity was assayed by determining the ability of serum to convert group 0 RBCs into A or B cells. RESULTS: Determination of serum ABO transferase activity was useful in the identification of Ael (3 cases), B. (2 cases), Bm (1 case), Am (1 case), Bx (1 case), 0 with weakened anti-A or anti-B (3 cases), and A without anti-B due to hypogammaglobulinemia (1 case). CONCLUSION: Determining serum A and B glycosyltransferase activity was proven to be a simple and useful tool for the classification of several ABO subgroups.(Korean J Blood Transfusion 10(1): 27-33, 1999)

Nineteen patients with large angle esotropia who have undergone bimedial rectus recession ranging from 7 to 8 millimeters were evaluated. We retrospectively reviewed preoperative and postoperative visual acuity, deviation, ocular motility, fusion, stereoacuity in all patients. The mean preoperative deviation was 76 prism diopters, ranging from 65 to 95 prism diopters and the mean postoperative follow up interval was 55.6 months, ranging from 26 to 80 months. The overall successful rate(horizontal orthotropia within+/-10 prism diopters) was 42.1%(8/19). The rate of undercorrection was 47.7%(9/19) and the rate of delayed consecutive exotropia was 10.5%(2/19). Fusion at near was found in 36.8%(7/19) and stereopsos of 200 seconds or better was found in 15.8%(3/19) of patients postoperatively.We observed no limitation of adduction or convergence. If reoperation was necessary, there still remain other untouched horizontal muscles on which to operate.Therefore, 7 to 8 millimeter medical rectus recession is the first effective procedure for the correction of large angle esotropia with deviations of more than 65 prism diopters.

A statistical observation was performed on 13,317 cases of neonates who had been delivered at Taegu Catholic Hospital during the past 3 years from Jan, 1st 1988 to Dec. 31st 1990. The results obtained were as follows: 1) Among 13,317 neonates, the male was 7,234 and the female 6,083, with the sex ratio of male to female being 1.19:1 2) Percentage distribution by birth weight was 5.6% for 2.500gm or less, 3.3% for 4,001gm or more. The mortality rate was 8.4 per 1,000 live births and 61.1% for very low birth weight infants. 57.1% of neonatal death occured within 24 hours after birth and the most common cause of death was prematurity (53.6%). 3) The mean growth data at birth were as following: Weight: 3,253+/-484gm in male, 3,160+/-456gm in female; Height: 50.11+/-2.59cm in male, 49.57+/-2.50cm in female; Head circumference: 33.60+/-1.74cm in male, 33.12+/-1.64cm in female; Chest circumference: 32.83+/-1.83cm in male, 32.41+/-1.75cm in female. 4) Among 13,317 noenates, 352 (2.6%) were under 37 wks and 555 (4.2%) above 42 wks and 92.6% very low birth weight infants under 37 wks. 5) 44.2% of 13,317 neonates, was the highest-density distribution which was between 47.5~52.4cm by length and 3,001~3,500gm by weighing. 6) The admission rate was 13.7% and the causes of admission in order of frequency were neonatal infection (47.9%), premature or low birth weight infant (12.9%), neonatal jaundice (11.3%), asphyxia neonatorum (6.9%), respiratory disress syndrome (5.4%), etc. 7) Among all neonates, 2.2% had neonatal asphyxia (a 1-minute Apgar score of 6 or less). The highest incidence was 19.7% in the breech delivery group by delivery mode and 33.6% in the prematurity by gestational age. 8) The types of delivery in order of frequency were spontaneous vaginal delivery (72.5%), Cesarean section (21.9%), vacuum delivery (5.0%), breech delivery (0.5%) and forceps delivery (0.1%). 9) The incidence of twin babies was 182 (91 pairs), 1.37% of all neonates, 1 pair per 145 neonates. Of all twins, 50.5% were below 2,500gm of birth weight and 20.9% premature. 10) The incidence of neonatal jaundice was 63.0%. Of icteric neonates, 8.2% had pathologic jaundice treated by phototherapy or exchange transfusion. 11) Among all neonates, there were 7,705 cases (57.9%) with high risk factors; the order of frequency was Cesarean section (37.8), meconium stained (13.3%), premature rupture of membranes over 24 hours (12.7%), birth weight 2,500gm or less (9.6%), etc.

The main trend moves towards early excision and skin grafting as treatment for the deep second degree burns and the third degree burns. The ability to excision & skin grafting. This study prospectively evaluated the ability of laser doppler flow measurements obtained within 72 hours after burn injury to predict the depth of burn wounds. A Periflux system 4001 laser doppler flowmetry had been used to measure cutaneous microflow circulation of 100 selected points of burn wounds in 44 admitted patients from March 1993 to February 1994. The mean value of superficial second degree burn checked by laser doppler was 194.6 perfusion unit(PU). The deep second degree burn was 59.7 PU and third degree burn was 5.1 PU. The blood flow of more than 100 PU reliably predicted the superficial second degree burn with 90.2 percents accuracy. The blood flow between 100 PU and 10 PU predict the deep second degree dermal burn with 96.2 percents accuracy. That of less than 10 PU predict the third degree burn with 100 percents accuracy. There was also a significant correlation between initial flow measurements and the depth of burn wounds. We conclude that laser doppler flow measurements performed early after burn injury are useful in predicting the depth of burn wounds. The laser doppler flowmetry has the advantage of being easy to use, noninvasive, provide immediate result for early determination of burn depth. The laser doppler flowmetry is useful in selecting patients for early excision and grafting of burn wounds.

PURPOSE: The purpose of this study was to determine current trends and the mode of future development in the field of medical radiology and to promote research among the nation's radiologists by analyzing the contents of the Korean Radiologic Society(JKRS) and Radiology. MATERIALS AND METHODS: The number of articles published in JKRS each year between 1990 and 1994 was counted. The research articles in JKRS(n=740) and in Radiology(n=1748) between 1992 and 1994 were categorized according to the objective, type, topic, materials, and radiologic techniques of their contents on the basis of predetermined criteria. Domestic Masters theses(n=126) and doctoral dissertations(n=75) accepted between 1990 and 1994, and domestic materials published in international journals(n=416) between 1986 and 1994 were also categorized using the same criteria. RESULTS: The greatest increase in the number of articles published in JKRS was seen during 1994. The majority of these aimed to retrospectively analyse the findings of diseases while the majority of articles published in Radiology dealt prospectively with the development and/or evaluation of diagnostic methods. More variety of topics and issues was seen in Radiology than in JKRS. The number of articles of domestic materials published in international journals increased from1986 to 1994, while the number of articles of foreign materials published in korea was relatively stationary. A significant number of theses and dissertations dealt, mostly prospectively, with studies of pathophysiologic and/or pharmacologic mechanisms using animal models. CONCLUSION: In order to understand both current trends and the direction and mode of future developments in the field of radiology, and to be able to actively deal with challenges at the forefront of radiologic development, it is essential to review research articles published in radiology-related journals.
