Clinical observation was performed on 81 cases who were received exchange transfusion at Ilsin Christian Hospital from January, 1986 to Decrmber, 1990. The results obtained were as follows: 1) Among 6,388 cases of neonatal jaundice, the exchange transfusion was performed on 81 cases (1.27%). 2) There was no sex predominance (male 40, female 41). The birth weight of 75 cases(92.6%) ranged from 2,500 gm 4,000 gm. 3) The most predominant delivery type was normal vaginal delivery (66 cases, 81.5%). Instrumental delivery was 9 cases (11.1%) that was higher than control group (4.2%). 4) Analysing the exchanged 81 cases, sepsis accounted for 28 cases (34.6%) of the total exchanged group:ABO incompatibility 25 cases (30.9%), complicated causes 13 cases(16.0%), unknown causes 12 cases (14.8%) and Rh incompatibility 1 cases (1.2%). 5) Repeated exchange transfusion was required in 12 cases (16.0%). 6) In 20 cases (24.7%), exchange transfusion was performed on 7 days or more after birth. In 4 cases (4.9%), including 1 cases of Rh incompatibility, exchange transfusion was done within 24 hours after birth. 7) The most common organism of sepsis, which was the most predominant etiology of exchange transfusion was E. coli in 12 cases (31.5%). 8) After exchange transfusion, serum bilirubin, Hb and reticulocyte count were decreased by 24%, 22% and 36%, respectively.

PURPOSE: Recurrent abdominal pain syndrome (RAPS) is not uncommon in school-aged children, but the etiology and pathogenesis are not understood well. But recent studies suggest that motility disorder makes up a majority of the pathogenesis. The aim of this study was to investigate gastric emptying time (GET) which is a method to evaluate gastrointestinal motility in patients with recurrent abdominal pain syndrome. METHODS: Radionuclide GET was investigated in 34 patients who visited the Department of Pediatrics, Pusan National University Hospital due to recurrent abdominal pain from January 1996 to June 1997. After 8 hours of fasting, the patient received two pieces of toast and a fried egg tagged with 2 mci of 99mTc albumin colloid and sequential counting was accomplished. We calculated the geometric mean of two counts measured from AP-PA scans and investigated 60 minutes of intragastric radionuclide retention rate. RESULTS: A total of 34 patients (12 boys, 22 girls, M : F=1 : 1.8) participated in this study. The age ranged from 5 to 12 years and the mean age was 8.8 years. Associated symptoms were headache (7 patients), nausea (7 patients), constipation (2 patients), vomiting (1 patient), and diarrhea (1 patient). Anti-Helicobacter pylori IgG Ab was positive in 4 cases. Endoscopic gastritis was found in 6 cases. The mean of 60 minutes of intragastric radionuclide retention rate was 72 +/- 17% and 27 cases (79%) were delayed significantly. CONCLUSION: The results of our study suggest that delayed gastric emptying time is a cause of abdominal pain in patients with recurrent abdominal pain syndrome.

Recently diabetic neuropathy has been postulated to occur from reduced availability of neurotrophic factor. This experiment was performed to identify the effect of nerve growth factor on dorsal root ganglia (DRG) in the strepto-zotocin-induced diabetic rat using morphometry and immunohistochemistry. The results obtained are as follows : 1. Unlike in the diabetic group where the type A and B cells were significantly decreased in their total numbers and sizes, these cells were normal in NGF-administered diabetic group. 2. Numbers of cells immunoreactive with SP and CGRP were also significantly decreased in the diabetic group. However, the NGF-administered diabetic group did not show any reduction in the number of these cells. 3. Mean sizes of cells immunoreactive with SP and CGRP cells were reduced in the diabetic group by 18.1% and 26.6% respectively (P<0.01). On the other hand, in NGF-administered diabetic group, mean sizes of SP-immunoreactive cells were increased (10.5%) which was not statiatically significant, and those of CGRP-immunoreactive cells were decreased (18%) compared to the control group (P<0.01). 4. In the diabetic group, many of nerve cell bodies showed some degenerative characteristics including neuron-satellite cell interface of irregular shape, the presence of a number of vacuoles and dense bodies, and nucleus of irregular contour. However, NGF-administered diabetic group exhibited neuron-satellite cell interface of regular form, many neurofilaments and neurotubules, and normal intracellular organelles. These results suggest that administration of NGF protects spinal ganglion cells from morphometric and morphological changes which are associated with a streptozotocin -induced diabetic neuropathy.

Background: Most unintentional injuries that occur at home are preventable. However, it may be difficult to sufficiently reduce the number of falls occurring at home by only identifying risk factors focused on specific age groups. Therefore, this study aimed to identify the risk factors (especially age and places where injuries occurred at home) for intracranial injury (ICI) caused by unintentional falls at home. Methods: Using the Emergency Department (ED)-Based Injury In-depth Surveillance, we analyzed the data of patients who visited the ED due to unintentional falls at home. Risk factors were identified using multivariable logistic regression according to age groups and interactions between place of injury occurrence and age groups, and sex and age groups were assessed. Results: In total, 232,124 patients were included in the analysis; older adults had a higher adjusted odds ratio (aOR) 14.05 (95% confidence interval [CI], 12.74–15.49) of ICI than infants. The corridor was associated with ICI in the male pediatric group (aOR, 2.71; 95% CI, 1.08–6.84) and the balcony with the female pediatric group (aOR, 2.04; 95% CI, 1.03–4.04). In the adult group, aOR of kitchen was 1.38 (95% CI, 1.02–1.88) in females and 0.56 (95% CI, 0.48–0.66) in males. Conclusion In this study, we identified the risk factors of ICI caused by falls at home using ED-based injury surveillance data. The risk of ICI was different among places of occurrence in the home depending on the age groups and sex.

Both adaptive and deleterious responses of cells to ethanol are likely triggered by short-term interactions of the cells with ethanol. Many studies have demonstrated the direct effect of ethanol on growth factor-stimulated cell proliferation. Using Swiss 3T3 cells whose growth was inhibited by ethanol in a concentration-dependent manner, we further investigated the molecular mechanisms of acute ethanol treatment by examining its effect on EGF- and PDGF-mediated cellular signaling systems for the mitogenic function. Tyrosine autophosphorylation of the growth factor receptors was partially prevented by ethanol in intact cells. When ethanol was included before or after EGF stimulation, no effect on the receptor signaling was observed. Here we also report that ethanol inhibits activation of ERK induced by both EGF and PDGF. EGF-induced JNK activation was reduced but PDGF-induced rapid JNK activation was delayed by the addition of ethanol. The balance between its inhibitory and stimulatory effect on the signaling molecules might determine the rate of cell growth.

BACKGROUND: It is known that hyperglycemia increase oxidative stress. Korean type 2 diabetic patients usually appear to be insulin deficient and insulin resistant. The blood glucose control can be normalized by the intensive insulin therapy. It has been reported that hyperinsulinemia have harmful effects on oxidative stress. The purpose of this study was to determine whether continuous subcutaneous insulin infusion (CSII) therapy by insulin pump affects the defense mechanism of oxidative stress in Korean type 2 diabetic patients. METHODS: Fasting blood from eighty three subjects was collected prior to starting CSII therapy using portable insulin pump and after hospitalization for 2 weeks. Serum and red blood cell lipid peroxide concentrations were analyzed by Yagi's methods. Serum tocopherol and vitamin C concentrations were measured by HPLC. Red blood cell glutathione peroxidase, superoxide dismutase and catalase activities were also measured. RESULTS: The mean age of subjects were 50.0+/-10.9 years, and they had diabetes for 8.4+/-5.8 years. Their average body mass index was 23.4+2.7 kg/m2. Their blood glucose levels were not controlled by oral hypoglycemic agents, diet and exercise treatment. Patients were divided into two categories according to blood glucose levels prior to CSII treatment. One category consists of patients with less than 11.1 mmol/L of average daily blood glucose levels prior to CSII treatment (the controlled group). The other category consists of patients with more than 11.1 mmol/L of average daily blood glucose levels (the uncontrolled group). Patients in the uncontrolled group had higher serum lipid peroxide levels than those in the controlled group before CSII therapy. After 2 weeks of CSII therapy, oxidative stress was not changed in controlled and uncontrolled groups. Serum insulin levels of all patients were increased after CSII treatment, but the levels before and after treatments were in the normal range, not hyperinsulinemic. Also, serum insulin levels did not correlate with serum lipid peroxide levels regardless of CSII treatment. Average serum vitamin C levels were remarkably increased after the therapy in all patients, but average serum total tocopherol levels was not altered. Also, activities of antioxidant enzymes such as glutathione peroxidase, superoxide dismutase, and catalase were not significantly changed. CONCLUSION: The blood glucose levels were normalized with the normal ranges of serum insulin levels after two weeks of CSII treatment. However, serum lipid peroxide levels were not changed even though serum vitamin C levels were increased. It is concluded that the oxidative stress of Korean type 2 diabetic patients are not changed after two weeks of CSII treatment, but there may be possibility the longer duation of CSII therapy may gradually improve oxidative stress.
