Korean Journal of Nuclear Medicine 1999;33(2):172-177
PURPOSE: The purpose of this study was to ascertain whether radiation adaptive response could be induced by Tc-99m-methylene diphosphonate (Tc-99m-MDP) in peripheral lymphocytes of patients undergoing bone scintigraphy. MATERIALS AND METHODS: Lymphocytes from 22 patients (6 males, 16 females, mean age 50+/-14 years) were collected before and after bone scintigraphy using 740 MBq Tc-99m-MDP. Lymphocytes from 10 controls (6 males, 4 females, mean age 43+/-7 years) were also collected. They were exposed challenge dose of 2 Gy gamma rays using a cell irradiator Number of ring-form and dicentric chromosomal per 600 cells (chromosomal aberrations) was counted under the light microscope. RESULTS: Chromosomal aberrations in patients before bone scintigraphy (385.1+/-30.5) was not different from that of controls (367.8+/-36.6). However, chromosomal aberrations in patients after bone scintigraphy was significantly decreased 192.6+/-22.1 (p=0.0001). CONCLUSION: Low dose gamma-irradiation by Tc-99m-MDP used for bone scintigraphy induces a cytogenetic adaptive response in peripheral lymphocytes.

The aim of present study was to determine the efficacy of immunotherapy with paternal lymphocytes for unexplained infertility. It has been apparent that reproductive success may be affected by the presence of abnormal autoantibodies. Unexplained infertility and repeated pregnancy wastage has been reported in the presence of abnormal autoantibodies. These data suffest that abnormal immune function may be an important pathologic entity contributing subfertility in patients with unexplained infertility. Therefore, immunotherapy may be a possible treatment modality for patients with unexplained infertility. Some investigators have reported that a proportion of infertile couples with repeatedly unsuccessful ET showed close histocompatibility similar to those of spontaneous recurrent abortion. Recently, it has been noted that immunotherapy with paternal lymphocytes achieves a high efficacy in preventing subsequent abortion in women with primary recurrent abortion of unknown cause, which was mediated by immune reaction including blocking antibody. To substantiate the hypothesis, we applied immunotherapy preceding Peritoneal Oocyte and Sperme transfer (POST) to 43 patients, 47 cycles of 82 patients, 89 cycles with at least three previous IUI failure from April, 1993 to February, 1995. There were no significant differences between treatment and control group in clinical response and hormonal response to controlled hyperstimulation. there was no significant difference between treatment and control group in pregnant rates per cycles (42.6% versus 28.6%), but a significantly lower abortion rate per pregnancy in treatment group, with 10.0% (2/20) compared with 50.03% (6/12) in control group. This study may suggest that immune therapy for patients with unexplained infertility with paternal lymphocytes might be beneficial.

Dieulafoy's vascular malformation is a rare cause of massive gastrointestinal bleeding. Most often it occurs in stomach within 6 cm from the gastroesophageal junction. Only a few cases have been reported to occur in the small intestine and colon. Occasionally, Dieulafoy's lesion of small intestine is difficult to recognize because of rarity, a paucity of symptoms and negative findings on barium studies. Therefore, this lesion needs to be considered in a patient with massive lower gastrointestinal bleeding. We report a case of Dieulafoy's vascular malformation in ileum 2 m proximal to ileocecal value in a 41-year-old woman who visited emergency clinic because of hematemesis, dizziness and vomiting. Small intestine revealed a wide-caliber artery within the submucosa showing intimal thickening, medial muscular hypertrophy and thrombosis.

OBJECTIVE: This study was performed to compare the clinical response to controlled ovarian hyperstimulation (COH) of in vitro fertilization and embryo transfer (IVF-ET) according to the size of baseline ovarian cyst. METHOD: From February 1992 to March 1999, a retrospective analysis was done of 272 cases who underwent COH using mid-luteal phase long protocol of gonadotropin-releasing hormone agonist (GnRH-a) for IVF-ET. These cases were divided into four group; group 1 (n=63) had cysts with mean diameters between 20.2 and 29.0 mm on their baseline ultrasound on cycle day 3, group 2 (n=57, 30.0~49.0mm), group 3 (n=68, >50.0mm) and control group (n=84). Cases were excluded according to the following criteria; pure male factor infertility, the presence of only one ovary, high CA-125 level and previous endometriosis. RESULTS: There were no statistically significant differences between cases with baseline ovarian cyst <50.0 mm in diameter and control group in any of the parameters. However, cases with baseline ovarian cyst>50.0 mm in mean diameter needed more amount of human menopausal gonadotropin (hMG), showed significantly lower estradiol (E2) level, the number of follicle >15.0 mm on the day of human chorionic gonadotropin (hCG) administration, the number of oocytes retrieved, the number of mature oocytes, and pregnancy rate compared with control group. CONCLUSION: This study suggests that cases with baseline overian cyst <50.0 mm in diameter do not adversely impact on IVF-ET outcome. However, cases with baseline ovarian cyst >50.0 mm in diameter had adverse effects on various parameters. Therefore, to improve the outcome of IVF-ET in these cases, ovarian cyst aspiration prior to initiating COH may be required.

This study was undertaken to evaluate the clinical usefulness of magnetic motor evoked potential (MEP) in the diagnosis of stroke and predicting the motor improvement following stroke. The cortical, cervical and lumbar stimulations were performed in the case of 24 healthy controls and 24 to a target muscle between after transcranial stimulation and after cervical or lumbar stimulation. There was no case showing no response in controls. But in 11 out of 24 ischemic patients, we could not get cortical MEP. Mean CMCT of abductor pollicis brevis muscle was not significantly different in controls and stroke patients in whom MEPs were recorded. There were significant differences between mean CMCT of normal controls and that of stroke patients showing MEPs in AH Muscle. MEP Results from testing the stroke patients were correlated with site of lesion, degree of motor weakness and motor improvement after 1 to 2 months. These results suggest that magnetic MEP is easy and useful in electrophysiological test of central motor pathway and is useful indicator for representing the motor weakness and predicting the motor outcome in acute ischemic stroke patients.

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.

Journal of the Korean Surgical Society 1999;57(6):850-857
BACKGROUND: Infantile Hypertrophic Pyloric Stenosis (IHPS) is one of the most common surgical problems of early infancy and one for which an eminently successful surgical treatment has been available since the work of Ramstedt in 1912. A clinical study was begun to access further the accuracy of ultrasonography in identifying hypertrophic pylorus. METHODS: This study is a retrospective clinical analysis of 31 cases of IHPS treated at the Department of Surgery of Pohang St. Mary's Hospital from Jan. 1990 to Dec. 1997. RESULTS: (1) The most prevalent age group was between 3 weeks and 8 weeks in 24 cases (77.4%), and the ratio of males to females was 5.2:1. (2) Among the 31 cases, new born babies were 21 cases (67.7%). (3) In 30 cases (96.8%), the gestational age was between 37 weeks and 42 weeks, and the birth weight was more than 3.5 kg in 21 cases (67.7%). The body weight percentile at admission was lower than the 50 percentile in 31 cases. (4) Among the 31 cases, breast-fed infants were 15 cases (48.4%), milk-fed 13 cases (41.9%), and mixed-fed 3 cases (9.7%). B type blood group was 23 cases (74.2%), and O type was 4 cases (12.9%). (5) In 4 cases (12.9%), an inguinal hernia was noted as an associated anomaly. (6) The onset of symptoms was neonatal (1 week-12 weeks) in all 31 cases, and the duration of the symptoms was between 1 week and 2 weeks in 18 cases (58.1%). (7) Non-bile stained, projectile vomiting was noted in all 31 cases (100.0%), an olive-shaped mass in right upper quadrant of the abdomen was felt in 27 cases (87.1%), and visible peristalsis on the epigastrium was noted in 25 cases (80.6%). (8) On laboratory tests, 17 patients had leukocytosis, and anemia was observed in 2 cases. Hypokalemia was observed in 9 cases (29.0%), hypochloremia in 4 cases (12.9%), and moderate to severe alkalosis (CO2 content > 25 mEq) in 7 cases. (9) Among the 25 cases, for which an the ultrasonographic evaluation was performed, the length of the stenotic canal was from 16 mm to 20 mm in 23 cases (92.0%), and the thickness of the stenotic portion was from 5 mm to 6 mm in 21 cases (84.0%). (10) All 31 cases were surgically treated by using a Fredet-Ramstedt pyloromyotomy, and the mortality was nil. The average hospitalization was 9.4 days. (11) There was 1 case of duodenal perforation and 1 case of intermittent non-projectile vomiting after the operation. CONCLUSIONS: We conclude that early accurate diagnosis, adequate preoperative preparation of the fluid & electrolyte imbalance, immediate surgical correction, and scheduled careful oral feeding are important in treatment of IHPS. Ultrasonographic determination of pyloric muscle length and thickness is the most accurate of the currently available techniques. A Fredet-Ramstedt pyloromyotomy is a safe and successful surgical procedure.

Anti-E and anti-c is one of the clinical significant irregular antibodies developing a delayed hemolytic transfusion reaction and hemolytic disease of the newborn. Since anti-c occurs frequently with anti-E in immunized people whosoe cells are E-and c-, it has been recommended to select blood of the patient's own R1 phenotype for transfusion, even when the presence of anti-c cannot be demonstrated in his/her serum. To determine the utility of this approach, we reviewed the blood bank laboratory records of patients identified anti-E and anti-c in his/her serum in Severance hospital over a 12 year period (1985-1996). During the 12-year period of study, 53 patients were identified with anti-E and/or anti-c; 30(56.6%) patients had anti-E alone, 6(11.3%) had anti-c, and 17(32.1%) had both. Thirty eight of forty two patients whose Rh-hr phenotypes were tested were R1R1. Of these 38 R1R1 patients, 16 patients (42.1%) presented with anti-c concomitant with anti-E. Ouru study showed that the incidence of antni-c in R1R1 patients with anti-E is similar to that of studies reported in Caucasian groups. We highly suggest the transfusion protocol of prophylactic use of c negative blood for R1R1 patients with anti-E. Furthermore, because anti-c may be present in concentrations too low to be detected, the enzyme technique is recommended in parallel with standard serologic methods for the identification of irregular antibodies.

Myocardial scintigraphy is a widely used noninvasive procedure with high sensitivity for the detection of patients with suspected coronary artery disease. The purpose of this study was to determine the prognostic value of a normal myocardial scintigraphy in 292 patients (150 males, 142 females, mean age 53+/-12 years) with chest pain who were followed from 7 to 58 (mean 25) months. Myocardial SPECT was performed with Tc-99m MIBI in 173 patients, with Tc-99m tetrofosmin in 74 patients and with T1-201 in 45 patients. During the follow-up period, there were 2 cardiac deaths and 2 nonfatal myocardial infarctions resulting in cardiac event rate of 1.37% (0.66% per year). The cardiac event rate was not different in patients with angiographically normal coronary arteries (1/30, 3.3%) and in those who had significant coronary a disease (2/27, 7.4%) (p=0.60). In conclusion, patients with chest pain and normal myocardial scintigraphy have a low cardiac event rate, and there was no significant difference of cardiac event rates between patients with normal and abnormal coronary angiograms.
