  • Purpose : To determine incidence, characteristics and risk factors associated with intrauterine intraventricular hemorrhage(IU-IVH) among premature infants. Methods : The medical records of infants with intraventricular hemorrhage(IVH) admitted to the neonatal intensive care unit of Asan Medical Center from January 1999 to June 2003 were reviewed retrospectively. Infants whose IVH with cystic change were detected within five days of life were defined as the IU-IVH group. The control group included those without any IVH. Various maternal and neonatal factors were evaluated between the IU-IVH and control groups, and risk factors for IU-IVH were identified using multiple logistic regression analysis. Results : The incidence of IU-IVH was 49/1024(15.9%). Mothers who are younger, primiparous, use less antenatal steroid, and neonates with greater incidence of neonatal respiratory distress syndrome, had higher incidences of IU-IVH compared to neonates with normal neurosonography. Risk factors associated with IU-IVH included neonatal respiratory distress syndrome and placenta infarct by placenta biopsy. Most infants with IU-IVH were ${\geq}1,501g$, ${\geq}34$ weeks gestational age and had low grade IVH. The size of the cysts associated with IU-IVH remained the same or disappeared in 96 %. IU-IVH does not seem to affect short-term neurodevelopmental outcome although a longer period of follow-up is needed. Conculusion : IU-IVH occurred mostly in ${\geq}1,501g$, ${\geq}34$ weeks infants with grade I IVH without developmental delays. However, the high incidence of total IVH merits more attention in terms of awareness of its existence as an unusual IVH among premature infants.

  • The main objective of this study is to investigate the effects of ovulation induction by treating HCG, LHRHa, GnRHa, ovaprim and pimozidein in long snout bullhead, L. longriostris. All hormons were injected into the muscles of back. Concentration of LHRHa to injection were 20, 50, 100, 150 and 200 ${\mu}g/kg$ and same concentration of LHRHa was injected after 24 hour. The ovulation induction rate was 100% and fertilization and hatching rates were 68.4, 45.2, 58.4 and 33.6% in 50 and 100 ${\mu}g/kg$. The times to ovulation were between 28 and 44 h. HCG was injected in long snout bullhead at 5,000, 10,000, 15,000, 20,000 and 25,000 IU/kg. The ovulation induction rate was 50% in 15,000 and 20,000 IU/kg. Fertlilzation and hatching rates were 55.2, 45.6, 52.8 and 44.8%. Ovulation time was between 72~80 h. HCG concentration of 500, 1,000, 2,000 and 4,000 IU/kg were injected with $50{\mu}g$ of LHRHa. Ovulation and hatching rates in 2,000 IU/kg were 75 and 35%. Ovulation time was 28~48 h. Ovaprim of 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 mL/kg were injected to the abdominal cavity. The ovulation induction rate was highest at 2.5 mL/kg to 50% and ovulation time was between 66~86 h. LHRHa concentration of 50, 100, 200, 300 and 400 ${\mu}g/kg$ was injected with pimozide (1,000 ${\mu}g/kg$). Ovulation induction rate was 87% at 100 and 200 IU/kg with pimozide. Ovulation time was between 66~86 h.

  • Aim: To evaluate the relationship between pre-operative CA-125 levels and myometrial invasion in patients with early-stage endometrioid-type endometrial cancer. Materials and Methods: Two-hundred and sixty patients were diagnosed with endometrial cancer between January 2007 and December 2012. Of these, 136 patients with stage 1 endometrioid histologic-type and documented pre-operative serum CA-125 levels were included in the study. Age, preoperative CA-125 level, histologic grade, surgical grade, and presence of deep myometrial invasion were recorded. Additionally, 16, 20, and 35 IU/ml cutoff values were used and compared to evaluate the relationship between pre-operative CA-125 levels and myometrial invasion. Results: The average serum CA-125 level was $35.4{\pm}36.7$ in patients with deep myometrial invasion, and $21.5{\pm}35.8$ in cases without deep myometrial invasion. The relationship between the presence of deep myometrial invasion and CA-125 cut-off values (16, 20, 35 IU/ml) was statistically significant, although the correlation was weak (p<0.05). When the relationship between 16, 20 and 35 IU/ml CA-125 cut-off values and the presence of deep myometrial invasion was studied, specifity and sensitivity values were identified as: 0.60-0.68 for 16 IU/ml; 0.73-0.48 for 20 IU/ml; and 0.89-0.33 for 35 IU/ml. The sensitivity of 16 IU/ml cut-off value was higher when compared to other values. Conclusions: This study demonstrates that preoperative serum CA-125 values maybe used as a predictive test in patients with early stage endometrioid-type endometrium cancer, and as a prognostic factor alone. Further studies should be conducted to identify different CA-125 cut-off values in patients with low risk endometrial cancer.

  • This study was performed to investigate the development of smoked chicken using old laying hens. Seventy two-weeks-old, spent laying hens were fed commercial feed (control) supplemented with 100 IU ${\alpha}$-tocopherol plus 10% squid liver oil (treatment) for 15 days and slaughtered. Smoked chickens were manufactured with spent laying hens in this study, Moisture and crude ash contents in smoked chicken of treatments were higher (P<0.05) than those of control group due to the feeding 100 IU ${\alpha}$-tocopherol plus 10% squid liver oil. No differences were observed in fatty acid and amino acid composition between control and treatments. In sensory evaluation, the springiness of smoked chicken was evaluated optimum for 32% consumer. The elastic, blend, specific flavor and smell of the smoked chicken of the treatment were not different from those of the control. However, 46% of tested panel answered that the springiness was higher in the treated-group due to the feeding 100 IU ${\alpha}$-tocopherol plus 10% squid liver oil. These results indicated that smoked chickens would be developed with spent laying hen after feeding 100 IU ${\alpha}$-tocopherol plus 10% squid liver oil and sensory evaluation.

  • Enzyme extracts of cellulase [filter paper cellulase (FPase) and carboxymethyl cellulase (CMCase)], chitinase, and chitosanase produced by Aspergillus niger NRRL-567 were evaluated. The interactive effects of initial moisture and different inducers for FP cellulase and CMCase production were optimized using response surface methodology. Higher enzyme activities [FPase $79.24{\pm}4.22$ IU/gram fermented substrate (gfs) and CMCase $124.04{\pm}7.78$ IU/gfs] were achieved after 48 h fermentation in solid-state medium containing apple pomace supplemented with rice husk [1% (w/w)] under optimized conditions [pH 4.5, moisture 55% (v/w), and inducers veratryl alcohol (2 mM/kg), copper sulfate (1.5 mM/kg), and lactose 2% (w/w)] (p<0.05). Koji fermentation in trays was carried out and higher enzyme activities (FPase $96.67{\pm}4.18$ IU/gfs and CMCase $146.50{\pm}11.92$ IU/gfs) were achieved. The nonspecific chitinase and chitosanase activities of cellulase enzyme extract were analyzed using chitin and chitosan substrates with different physicochemical characteristics, such as degree of deacetylation, molecular weight, and viscosity. Higher chitinase and chitosanase activities of $70.28{\pm}3.34$ IU/gfs and $60.18{\pm}3.82$ to $64.20{\pm}4.12$ IU/gfs, respectively, were achieved. Moreover, the enzyme was stable and retained 92-94% activity even after one month. Cellulase enzyme extract obtained from A. niger with chitinolytic and chitosanolytic activities could be potentially used for making low-molecular-weight chitin and chitosan oligomers, having promising applications in biomedicine, pharmaceuticals, food, and agricultural industries, and in biocontrol formulations.

  • Equine motor neuron disease (EMND) is a spontaneous neurologic disorder of horses, which results from the degeneration of motor neurons in the spinal cord and brain stem. An 8-year-old Jeju pony gelding presented with weight loss, muscle tremors, frequent recumbence, low head carriage, sweating, and standing with four limbs close together. The gelding has been on the same stable and limited access to pasture for several years. The gelding has been fed with dried hays and commercial concentrated feeds. Laboratory test revealed very low serum vitamin E level (0.14 ${\mu}g/mL$; reference range > 1.5 ${\mu}g/mL$), mildly elevated creatine kinase (402 IU/L; reference range 119-287 IU/L) and aspartate aminotransferase (876 IU/L; reference range 226-336 IU/L). Oral glucose absorption test showed decreased glucose absorption. Histopathologic examination using a biopsy specimen from sacrocaudalis dorsalis medialis muscle revealed atrophic and hypertrophic muscle fiber, centralization of nucleus, degenerating and necrotic muscle fibers. Taken together, the gelding was diagnosed as EMND. After oral vitamin E administrated for 5 weeks, the gelding showed normally improved stance, decreased periods of recumbency, improved head carriage and weight gain except consistent tremors. This is the first report that successfully treated EMND case occurred in a Jeju pony in Korea.

  • The Purpose of this study was to determine the serum content of LH, FSH and prolactin. Blood samples collected from day 20 prepartum to 20 postrtum in 8 sows. LH, FSH and prolactin were assayed by radioimmunoassay methods. LH levels increased from 2.3 mIU/$m\ell$ day 6 prepartum to 5.8 mIU/$m\ell$ by day +2 and remained quite constant thereafter. The mean serum FSH increased from 7.5mIU/$m\ell$ day 6 prepartum to 10.0 mIU/$m\ell$ at the time of parturition, but the difference in LH and FSH patterns reported here provide further evidence that the controlling mechanisms for the two gonadotropins are independent. Prolactin reached a peak mean level of 68.5ng/$m\ell$ at day 0.

  • The objective of this study was to evaluate the effects of different levels of ${\alpha}$-tocopherol and selenium in broiler diets on performance and physicochemical properties of chicken thigh meat. A total of 360 broiler chicks divided into six groups were fed a basal diet (control) or basal diet supplemented with 50 IU ${\alpha}$-tocopherol/kg (T1), 100 IU ${\alpha}$-tocopherol/kg (T2), 200IU ${\alpha}$-tocopherol/kg (T3), 0.3 ppm selenium/kg (T4), and 100 IU ${\alpha}$-tocopherol/kg + 0.3 ppm selenium/kg (T5) for five weeks. Growth performance and proximate composition of chicken thigh meat were not influenced by all dietary treatments, except for crude fat, which was significantly lower in the treatment with ${\alpha}$-tocopherol or selenium, or both compared to control. The dietary ${\alpha}$-tocopherol and selenium supplementation had no significant effects on pH, CIE $L^*$ (lightness), and $b^*$ (yellowness) values but TBARS (thiobarbituric acid reactive substance) values were decreased (P<0.05) by the addition of ${\alpha}$-tocopherol and selenium. CIE $a^*$ (redness) values increased significantly with added ${\alpha}$-tocopherol and selenium relative to the control (P<0.05). Likewise, changes in fatty acid composition in chicken thigh meat with the dietary supplementations with ${\alpha}$-tocopherol, selenium and their combination significantly increased (P<0.05) unsaturated fatty acid, whereas saturated fatty acid were decreased. It was concluded that the addition of 200 IU ${\alpha}$-tocopherol (T3) and 100 IU of ${\alpha}$-tocopherol plus 0.3 ppm selenium (T5) were most effectiveness in the improvements in the lipid oxidative stability of chicken meat when compared to the control.

  • Purpose: Virus-associated rhabdomyolysis is very rare. We report 15 patients with rhabdomyolysis caused by various viruses. Methods: Fifteen patients who were diagnosed with rhabdomyolysis and a viral infection were included in this study. Clinical, laboratory, and radiologic findings were evaluated through retrospective chart reviews. Results: Chief complaints were severe bilateral lower leg pain and leg weakness. The median age was 5.7 years. The male:female ratio was 2:5. The viral infections were caused by influenza virus B, parainfluenza virus, and rhinovirus. One patient with influenza virus B had coinfection with coronavirus. Median initial laboratory values and ranges were as follows: serum creatinine, 0.4 (0.1-0.5) mg/dL; serum aspartate transaminase, 124 (48-1,098) IU/L; serum alanine transaminase, 30 (16- 1,455) IU/L; serum creatine kinase, 2,965 (672-16,594) IU; serum lactate dehydrogenase, 400 (269-7,394) IU/L; serum myoglobin, 644 (314-3,867) ng/mL; urine myoglobin, 3 (3-10,431) ng/mL. All patients recovered without complications. Conclusion: This is the first report of the simultaneous occurrence of rhabdomyolysis caused by various viruses. This is also the first report of rhinovirus-associated rhabdomyolysis.

  • Coxsackievirus A16 (CA16), which primarily causes hand, foot, and mouth disease (HFMD), is associated with complications, such as encephalitis, acute flaccid paralysis, myocarditis, pericarditis, and shock. However, no case of pancreatitis associated with CA16 has been reported in children. We report a case of CA16-associated acute pancreatitis in a 3-year-old girl with HFMD. She was admitted because of poor oral intake and high fever for 1 day. Maculopapular rashes on both hands and feet and multiple vesicles on the soft palate were observed on physical examination. She was treated conservatively with intravenous fluids. On the fourth hospital day, she had severe abdominal pain and vomiting. The serum levels of amylase and lipase were remarkably elevated (amylase, 1,902 IU/L; reference range, 28-100 IU/L; lipase, >1,500 IU/L; reference range, 13-60 IU/L), and ultrasonography showed diffuse swelling of the pancreas with a small amount of ascites. The real-time reverse transcription polymerase chain reaction result from a stool sample was positive for CA16. CA16 can cause acute pancreatitis, and should be considered in the differential diagnosis of abdominal pain in children with HFMD.
