In our investigation, various immunologic aspects of 129 patients with complete and incomplete type of Behcet's syndrome were taken under consideration : quantitation of total T-cells by E-rosette method and B-cells by EAC-rosette method, helper/inducer T and suppressor/cytotoxic T-cells by monoclonal antibody technique(OKT4, OKT8), lymphocyte transformation test with PHA, quantitation of serum r-globulin by electro phoresis and quantitations of serum IgG, IgA, IgM, C3, C4 by immunodiffusion. From the results, the cell mediated immunity in Behcet's syndrome is not influenced by the number of patterns of four major symptoms or the activity of each major symptom at the time of test. However the humoral immunity is considered to be influenced by the above parameters.

OBJECTIVE: The changes of the production of nitric oxide in preeclampsia are still controversial. To determine the changes of nitric oxide production in preeclamptic pregnancies, NOS activity and eNOS and iNOS expression in preeclamptic placentae were compared with those in normal placentae, and to determine the changes of nitirc oxide production according to the sites of placenta, NOS activity and eNOS expression in preeclamptic placentae were also compared with those in normal placentae. METHODS: Human placentae were obtained from 15 normal and 15 preeclamptic pregnant women at the time of cesarean section. NOS activity was assessed by measuring the conversion of [3H]-arginine into [3H]-citrulline. The eNOS and iNOS expression were assessed by using western blot analysis. Data were analyzed by Student t-test and paired t-test where appropriate. RESULTS: The NOS activity(judged by measurement of [3H]-citrulline production) was significantly increased in preeclamptic placentae compared to normal(P<0.05). In normal and preeclamptic pregnant placentae, the NOS activity in main stem villi was increased compared to that in terminal villi. However, the difference of NOS activity between main stem villi and terminal villi was not significant(P>0.05). Quantification of the autoradiographic images demonstrated that the integrated optical density of the immunoreactive bands of eNOS were significantly lower in preeclamptic placentae compared to normal(p<0.05). Conversely, the integrated optical densities of the bands of iNOS were significantly higher in preeclamptic placentae compared to normal(p<0.05). CONCLUSIONS: Although the eNOS expression in preeclamptic placentae was lower than that in normal placentae, the NOS activity was significantly higher in preeclamptic placentae than that in normal in this study. These are result from increased production of iNOS in the compensatory mechanisms for the decreased nitric oxide production in pre-eclamptic placentae.

The measurement of blood pressure in neonates is an important diagnostic procedure. But the measurement of blood pressure has not been performed routinely because of difficulty in measuring blood pressure and variable normal range according to measuring apparatus. Recently some accurate and convenient apparatus of measuring blood pressure have been introduced in neonatal care, so the reference values of neonatal blood pressure may be obtainable. The authors measured systolic and diastolic blood pressure using a noninvasive oscillometric monitor instrument on 1,3,6,12,24,48,72 hours of life in 200 neonates born at Eulji General Hospital, Taejon. And we analysed the results according to birth weight, gestational age, delivery type, sex, meconium stain, preeclampsia and hypocalcemia. The following results were obtained: 1) On the 1st day of life, systolic and diastolic blood pressure were 65.611.7 mmHg and 36.7+/-5.8 mmHg in the normal birth weight neonates, and 56.2+/-6.7 mmHg and 34.14.2 mmHg in the low birth weight neonates, respectively. So the blood pressure of normal birth weight neonates were higher than that of low birth weight neonates. 2) On the 1st day of life, systolic and diastolic blood pressure were 65.5+/-11.8 mmHg and 36.6+/-5.8 mmHg in the fullterm neonates, and 57.6+/-5.2 mmHg and 35.6+/-3.8 mmHg in the preterm neonates, respectively. So the blood pressure of full term neonates were higher than that of preterm neonates. 3) The difference of blood pressure in analysis according to birth weight were wider than that according to gestational age. 4) The blood pressure of neonates were lowest on the 3 hours of life and increased gradually during 72 hours of life. 5) The blood pressure of neonates did not show any significant difference in analysis according to sex. delivery type, Meconium stain, preeclampsia, and hypocalcemia.

This study was undertaken to investigate immunological mechanisms in Behçet's syndrome, a function considered important in the pathogenesis of the disease. The activity of interleukin-2 (IL-2), which is believed, to play a central role in the regulation of both cell-mediated and humoral T cell-dependent immune responses, measured in 46 patients with complete, in-complete or suspected Behçet's syndrome. The results were as follows: 1 . There was no significant difference between the average IL-2 activity of patients and control group. 2. For each clinical subtype of Behçet's syndrome, IL-2 activity was lower than the control value, but the difference was not statistically significant. 3. In mucocutaneous and ocular types, the greater the clinical symptoms, the lower the value of IL-2 activity. However, the decrease of IL-2 activity was not statistically significant. In conclusion, IL-2 activity of phytohemaggludnin (PHIS-stimulated peripheral blood lymphocytes in patients with Behçet's syndrome was not significantly decreased compared to control population.

This study helps to clarify conflicting reports by comparing the physical properties and accuracy of complete denture processed by the pack and press technique, continuous-pressure injection technique(SR-Ivocap system) and Mark press technique. The 6 different specimens have been evaluated using the SEM, Impact test, DSC (Differential Scanning Calorimetry) and DMTA(Dynamic Mechanical Thermal Analysis). Each sample was made of SR-Ivocap resin and QC-20 resin by different processing methods. The results were as follows ; 1. As the result of the observation on the fracture surface of resin by use of SEM, sample SR-Ivocap resin cured by continuous pressure injection method showed the most homogeneous structure. This is why molecules in SR-Ivocap resin have no orientation. 2. As the result of the Impact test in order to measure the deformity, fracture energy and impact resistance of resin, the samples with QC-20 acrylic resin and SR-Ivocap resin cured by continuous pressure injection method were exellent. 3. In consequence of measuring alpha-glass transition temperature by use of DSC on the basis of temperature change, the glass transition temperatures of sample QC-20 resin cured by pack and press method and sample SR-Ivocap resin cured by continuous pressure injection method were very similar. Thus volumetric stability could not be evaluated only by glass transition temperature. 4. In comparing volumetric stability data by DMTA, the glass transition temperature(Tg) showed 137.88degrees C at sample QC-20 resin cured by pack and press method and 139.78degrees C at sample SR-Ivocap resin cured by continuous pressure injection method. Therefore sample SR-Ivocap resin cured by continuous pressure injection method seems to be superior to sample QC-20 resin cured by pack and press method in the dimensional stability at high temperature. 5. In comparing storage modulus data by DMTA, the storage modulus of sample SR-Ivocap resin cured by continuous pressure injection method was higher than that of sample QC-20 resin cured by pack and press method. So, sample SR-Ivocap resin cured by continuous pressure injection method seems to be superior to sample QC-20 resin cured by pack and press method in impact strength.

We managed three cases of anesthesia for living related liver transplantation from December 1994 to July 1995. Donors were recipient's parents and two of them were 35-year old man, the other was 25-year-old woman. The recipients were suffered from congenital liver diseases (two of them were diagnosed as biliary atresia and the other Byler's disease). They had presented severe jaundice and cholangitis and their mean age & body weight were 15 +/- 4.9 months and 8.6 +/- 1.22 kg, respectively. Average duration of anesthesia was about 15 hours, and anhepatic time was 140 minutes, 80 m inutes and 50 minutes, respectively. Careful attention was paid to body temperature, serum potassium, ionized calcium, blood coagulation function, as well as to general condition and respiratory function. Hemodynamic value was relatively stable through out the operation and postoperative mechanical ventilatory support was required for about 3 days.
