A case of neonatal diabetes mellitus is described. The child presented with low birth weight but was normal in appearance. She was acidotic and ketonuria was observed. The HLA typing was DR1 and 3, and insulin autoantibodies were negative. Genetic analysis with polymorphic DNA markers for chromosome 6 indicated biparental inheritance. She required insulin therapy for the control of hyperglycemia, and insulin dependence continues after 8 months of age.

Platelet-rich plasma (PRP) has been known to increase the rate and degree of bone formation by virtue of growth factors in concentrated platelets. Although its great healing effect on bone defect or pre-implantation site preparation in conjunction with bone substitute has been reported, the effect associated with implant is unknown. The purpose of this study was to investigate the effect of PRP on rapid osseointegration of endosseous dental implants in the rabbit tibiae. Twenty two adult female New Zealand white rabbits, weighing approximately 2.7-3.3kg, were used for this study. Twelve of the 22 animals were used for histomorphometric analysis and ten of the 22 were for removal torque test. Each animal received two implants in each tibia (two treated with PRP and two as control) and was given fluorochrome intramuscularly. For histomorphometric analysis, rabbits were divided into four groups according to the healing period. At 1 week, 2 weeks, 4 weeks and 8 weeks postoperatively, each three animals were sacrificed serially and the amount and rate of bone formation around dental implant were examined on the undecalcified sections under fluorescent microscope, polarized microscope and light microscope connected to a personal computer equipped with image analysis system. For removal torque test, rabbits were divided into two groups and removal torque tests were performed at 4 weeks, 10 weeks after implant placement. In total, 88 screw shaped, commercially pure titanium implants (Neoplant, Neobiotech, Seoul, Korea) were used in this study. Labeling pattern reflected differences of two groups in bone formation rate at each period. Histomorphometrically, PRP group showed significantly higher bone volume within threads compared to control group at 2 weeks (70.30+/-4.96% vs. 50.68+/-6.33%; P<.01) and 4 weeks (82.59+/-5.94% vs. 72.94+/-4.57%; P<.05). PRP group at 1, 2 and 4 weeks revealed similar degree of bone volume formation comparable to control group at 2, 4 and 8 weeks, respectively. On the other hand, while PRP group showed higher bone-implant contact (47.37+/-8.09%) than control group (33.16+/-13.47%) at 2 weeks, there were no significant differences between PRP group and control group for any experimental period. Removal torque values also showed no significant differences between PRP group and control group at any experimental period (P>.05). These findings imply that PRP could induce rapid, more bone formation around implant during early healing period and get faster secondary stability for reducing healing period, though it has not induced bone maturation enough to resist functional loading.

Uterine sarcoma whieh is originated from uterine muscle and/or connective tissues, is very rare malignant tumor and is the most lethel of all primary uterine tumors. This study was undertaken to correlate the clinieal findings, diagnoses, managements and ultimate outcome of each particluar grouy of uterine sarcoma at Depart,ment of Obstetrics and Gynecology in Korea University Hospital. The reaults were as follows, 1. The distribution of uterinesarcomaby histologic type was 5 cases (35.7%) for leiomyosarcoma, 5 cases (35.7%) for endometrial strornal sarcoma and 4 eases (28.6%) for mixed Mullerian tumor, 2. The mean age and yarity were 50.8 years and 3.1. 3. The most common syrrlptorn was irregular vaginal bleeding (64.3%), and lower abdominal pain (21.4%), abdominal palpable mass (14.3%) in order of frequency. 4. The distribution by YIGO clinical atage was 35.7% for stage I, 35.7% for stage II, 7.2% for stage IE and 21.4% for stage lV. The average survival time of each stage of disease was decreased with increasing stage. 5. The mean survival time was decreased with inereasing numbers of mitotic figure per 10 high power fields. 6.

Reactive airways dysfunction syndrome (RADS) is a syndrome as a persistent bronchial hyperreactivity with asthmatic dyspnea which occurs after one or more inhalation exposures to a high concentration of irritant gasses, smokes or vapors in subjects who had preciously had no respiratory disease. We report a case of a 34 years old female worker suffering from reactive airways dysfunction syndrome who had been taking charge of guest room cleaning at a condominium. 7 months before, she inhaled high concentration of chlorine gas in confined and poor ventilated working space of bathroom at the condominium. As she was washing a bathroom with a bleaching agent (6 % sodium hypochlorite) without dilution, dyspnea, dizziness, headache, nausea, and coughing developed after work. She still suffer from dyspnea and coughing. All functional tests were normal except for methacholine challenge test which reveals bronchial hyperreactivity. She has some symptoms of dyspnea and coughing when exposed to perfume, cold air, and heavy work.

Urotensin II (UII) is a mitogenic and hypertrophic agent that can induce the proliferation of vascular cells. UII inhibition has been considered as beneficial strategy for atherosclerosis and restenosis. However, currently there is no therapeutics clinically available for atherosclerosis or restenosis. In this study, we evaluated the effects of a newly synthesized UII receptor (UT) antagonist, KR-36996, on the proliferation of SMCs in vitro and neointima formation in vivo in comparison with GSK-1440115, a known potent UT antagonist. In primary human aortic SMCs (HASMCs), UII (50 nM) induced proliferation was significantly inhibited by KR-36996 at 1, 10, and 100 nM which showed greater potency (IC₅₀: 3.5 nM) than GSK-1440115 (IC₅₀: 82.3 nM). UII-induced proliferation of HASMC cells was inhibited by U0126, an ERK1/2 inhibitor, but not by SP600125 (inhibitor of JNK) or SB202190 (inhibitor of p38 MAPK). UII increased the phosphorylation level of ERK1/2. Such increase was significantly inhibited by KR-36996. UII-induced proliferation was also inhibited by trolox, a scavenger for reactive oxygen species (ROS). UII-induced ROS generation was also decreased by KR-36996 treatment. In a carotid artery ligation mouse model, intimal thickening was dramatically suppressed by oral treatment with KR-36996 (30 mg/kg) which showed better efficacy than GSK-1440115. These results suggest that KR-36996 is a better candidate than GSK-1440115 in preventing vascular proliferation in the pathogenesis of atherosclerosis and restenosis.

Valproic acid is a commonly prescribed medication approved for epilepsy, migraine and bipolar disorder. The common adverse effects associated with valproic acid include nausea, vomiting, tremor and weight gain. Less common but more serious adverse effects can occur. These include irreversible hepatotoxicity and pancreatitis. We report one case of pancreatitis, an uncommon disorder in children, in an 11-year-old boy treated with valproic acid for simple partial seizure.

This study examined, among others, the relationship between the use of anticonvulsant and the bone mineral metabolism(measured via DR-XRA and biochemical study) in 46 adult epileptic outpatients who had been on anticonvulsant for more than one year at Seoul Red Cross Hospital. The study finding wet as follows. 1) There was statistically significant difference between index group(i.e. 46 adult epileptic outpatients) and control group(i.e. 46 healthy adults without previous exposure to anticonvulsant) in terms of bone mineral density. Specifically, the bone mineral density in the epileptic outpatients was significantly lower than that in the healthy adult. Although there was no statistically significant difference between male and female outpatients, their bone mineral density tended to decrease with the increase of age. 2) The bone mineral density in the epileptic outpatients was negatively correlated to both I) the age when the outpatients stared anticonvulsant treatment and ii) the period for which the outpatients were on anticonvulsant 3) Index group was further classified into three subgroup(i.e. low, normal and high subgroup) based on the mean and standard deviation of the bone mineral density in healthy adults control group. 24 outpatients(52.5%) out of 46 fell into low subgroup, of which 10 were male. Overall, there was no statistically significant difference between male and female outpatients in terms of their bone mineral density. 4) Low subgroup's average age(38.6 with SD of 12.5) was significantly higher than those of the other two subgroup. Low subgroup stained anticonvulsant treated when their average age was 24.8(SD 15.0) years, which was higher than those of the other two subgroups. Low subgroup was on anticonvulsant, on average, far 13.3(SD 7.6) years, which was also higher than those of the other two subgroups although there was no significant difference among the subgroups. 5) A series of comparison regarding the possible impact of various types of anticonvulsan(e.g. PHT, CBZ, FB, SV) in terms of i) overall dosage and ii) daily average dosage on bone mineral density showed no significant difference across the three subgroups. 6) There was no significant difference in terms of bone mineral density between the epileptic outpatients on only one type of anticonvulsant and those on two or more types of anticonvulsant. 7) A biochemical study showed that i) each subgroup fell into normal range in terms of blood serum Ca, F, and ALF with no significant difference among the subgroups, and ii) in low subgroup, there were 6 outpatients(25%) with Ca decrease, 2(9.5%) with P decrease, and 5(20.8%) with ALF increase.

Three-types of expandable metallic stents were constructed to evaluate the differences between the stents : one, formed in a cylindrical zigzag pattern with stainless steel wire (Gianturco stent), another, made by coating the Gianturco stent with silicone rubber(Silicone stent), the third, made by coating the Gianturco stent with 24 carat gold(God stent) for tissue acceptance. A total of 69 stents(each 23 stents of Glanturco, Silicone, and Gold stents) of 8-12 mm in diameter and 20 mm long were placed into normal abdominal aorta, inferior vena cava and iliac artery of nine adult dogs for 2 weeks to 11 months. It was more difficult to introcuce Silicone stent into an introducing sheath than Gianturco or Gold stent due to the thickness of silicone rubber, Four Gianturco stents and three Silicone stents showed migration but Gold stent did not. Luminal narrowing or occlusion was noted in 3 Silicone stents, in 2 Gianturco stents, and in 1 Gold stent. Neointimal proliferation over the stent wires was more rapid and even in God stent than Silicone or Gianturco stent. Although further study is needed, Gold stent seems to be better than Gianturco or Silicone stent as an endovascular graft material.
