The HUMACTBP2 locus was investigated to collect population genetic data in the Korean population and to evaluate the applicability for the forensic field. An Automatic fluorescent-based sequencer (377 automatic DNA sequencer, ABI) was used to detect amplified fragments of the HUMACTBP2 locus electrophoresed on 4% denaturing polyacrylamide sequencing gels. ACTBP2 allelic ladder consisting of different sizes of 18 alleles was constructed and employed as an internal size standard in combination with a GS-350 size standard for precision of allele-band sizing. By utilizing different fluorescent dyes, both the allelic ladders and samples were able to be analyzed in the same lane by 99% orecision of allele-band sizing. Among the Korean population (n=224), 26 alleles in the range of 239-313 bp are determined. allele No. 6 is found 45 times (0.100) which is mostly frequent, and the rest of allele is distributed with their relative frequency of 0.002-0.100. The comparison between observed and expected numbers of homozygous and heterozygous individuals confirms that ACTBP2 locus is in the state of Hardy-Weinberg equilibrium among the Korean population. The heterozygosity is 0.9389+/-0.0034(93.89%), and the power of discrimination(PD) and power of exclusion(PEX) are calculated to be 0.991(99.1%)and 0.890(89.0%), respectively, showing the high informativeness for individual identification. Thus, these results mean that the HUMACTBP2 locus can effectively be used for the forensic application.

Although trivalent subunit vaccine has been available, the influenza vaccine has been under-utilized because of cumbersome route of vaccination and low level of protection. Therefore, there has always been a great need to develop live attenuated influenza vaccine which can be administered through nasal route and elicit better immunogenicity. Through conventional repeated passage at low temperature, a live influenza vaccine carrier could be established. By reassortant formation between the 'cold- adapted' vaccine carrier and virulent strains, a prototype of trivalent live influenza vaccine is developed. Influenza A virus was adapted to replicate at low temperature. Serial passage at progressively lower temperature (30degrees C, 27degrees C and 24degrees C)resulted in the generation of cold-adapted (ca), temperature-sensitive (ts) mutant and attenuation (att) phenotype. This strain was evaluated for their ability to protect mice from challenge with same subtype and different subtype of influenza A virus. The study showed that vaccination of mice with live attenuated influenza virus provided complete protection against homologous and heterologous virus challenge. We also evaluated therapeutic potential of ca influenza virus. The mice infected with ca virus before challenge with wild type viruses or infected with simultaneously showed reduced clinical symptoms suggesting potential therapeutic effects.

BACKGROUND: Tianeptine is an antidepressant drug which is used for treating depression. Interestingly, the tianeptine has shown antinociceptive effects within a variety of nociceptions. The aim of this study is to investigate the antiallodynic effects of tianeptine in neuropathic pain rats and also determine the involvements of serotonergic, alpha-2 adrenergic and adenosine receptors at the spinal level. METHODS: Neuropathic pain was induced by ligation of left lumbar at 5th and 6th spinal nerves in male Sprague-Dawley rats. PE-10 catheters were placed into the thoracolumbar subarachnoid space for drug injections. Mechanical allodynia was evaluated by measuring the withdrawal threshold to von Frey filament when applying on the plantar surface of rats. The effects of intrathecal tianeptine were observed at 15, 30, 60, 90, 120, 150, 180 minutes after delivery. Antagonists for serotonergic (dihydroergocristine), alpha-2 adrenergic (yohimbine) and adenosine (CGS 15943) receptors were intrathecally administered 10 minutes prior to tianeptine in order to evaluate the involvement of both receptors. RESULTS: Intrathecal tianeptine increased dose-dependently at the withdrawal threshold in the ligated paw. Pretreatment with intrathecal dihydroergocristine, yohimbine and CGS 15943 antagonized the antiallodynic effects of tianeptine. CONCLUSIONS: These results suggested that intrathecal tianeptine attenuates the spinal nerve ligation induced tactile allodynia. Serotonergic, alpha-2 adrenergic and adenosine receptors are all involved in the antiallodynic effects of tianeptine at the spinal level.

Optic neuritis refers to any inflammatory disorder of optic nerves, but it usually denotes an acute or subacute disease of optic nerves attributed to inflammation associated with demyelination. The diagnosis of optic neuritis is usually made on a clinical ground. The condition usually presents as a painful subacute unilateral loss of vision, which progresses over a few days to 2 weeks. The pain varies in severity, although it typically does not interfere with sleep. We report 2 cases of atypical optic neuritis rapidly recovered by the administration of high doses of steroid that presented with severe eyeball pain accompanied by vague visual loss and painlessly insidious onset of visual loss respectively, with normal findings in fundoscopic examinations, visual evoked potentials and orbital MRIs.

PURPOSE: Febrile seizure, the most common type of pediatric convulsive disorder, is a benign seizure syndrome distinct from epilepsy. However, as epilepsy is also common during childhood, we aimed to identify the prognostic factors that can predict epilepsy in children with febrile seizures METHODS: The study comprised 249 children at the Korea University Ansan Hospital who presented with febrile seizures. The relationship between the subsequent occurrence of epilepsy and clinical factors including seizure and fever-related variables were analyzed by multivariate analysis. RESULTS: Twenty-five patients (10.0%) had additional afebrile seizures later and were diagnosed with epilepsy. The subsequent occurrence of epilepsy in patients with a history of febrile seizures was associated with a seizure frequency of more than 10 times during the first 2 years after seizure onset (P<0.001). Factors that were associated with subsequent occurrence of epilepsy were developmental delay (P<0.001), preterm birth (P=0.001), multiple seizures during a febrile seizure attack (P=0.005), and epileptiform discharges on electroencephalography (EEG) (P=0.008). Other factors such as the age at onset of first seizure, seizure duration, and family history of epilepsy were not associated with subsequent occurrence of epilepsy in this study. CONCLUSION: Febrile seizures are common and mostly benign. However, careful observation is needed, particularly for prediction of subsequent epileptic episodes in patients with frequent febrile seizures with known risk factors, such as developmental delay, history of preterm birth, several attacks during a febrile episode, and epileptiform discharges on EEG.

This study was designed to introduce free toe tissue transfer using infiltration method of local anesthetic agent. Four toe pulp tissues were transferred to reconstruct finger tip defect in four patients who were not suitable for general anesthesia. Two flaps taken from the lateral side of the great toe was used for reconstruction of thumb defect and two flaps from the medial side of the second toe for resurfacing of the index and fifth finger. Flap sizes were various from 2.0x2.0 cm2 to 1.6x4.0 cm2. Anesthesia was induced by infiltration of 2% lidocaine hydrochloride (with 1:100,000 epinephrine) with dilution of normal saline in same volume unit, as like as in ordinary digital block. All vessels were anastomosed within 2 cm of distance from the proximal margin of the defect. Whole operative procedures were carried out by one team. All flaps were successfully taken without complication. The average operation time was 4 hours 10 minutes. The amount of anesthetic agent used in whole operative procedures was roughly 4 mL in the toe, 8 mL in the finger, and 12 mL totally. In conclusion, free toe tissue transfer using infiltration method of local anesthetic agent would be good strategy for finger tip reconstruction in the patient not suitable for general anesthesia.

BACKGROUND: We studied the association of sagittal abdominal diameter (SAD) and metabolic syndrome and insulin resistance in Korean adults. METHODS: This is a cross-sectional study by 190 patients who visited a Health Promotion Center of National University of Pusan from 11 November to 14 November, 2008. We analyzed the association of anthropometry (waist circumference, BMI, SAD), insulin resistance (homeostatic model assessment-insulin resistance, HOMA-IR), insulin sensitivity (quantitative insulin sensitivity check index, QUICKI), and plasma concentrations of glucose, insulin, total cholesterol, LDL, HDL, triglyceride. SAD was categorized into quartiles and assessed odds ratio of metabolic syndrome adjusted for age, sex, lifestyle factors. RESULTS: SAD showed significance correlation to HOMA-IR than BMI. Quartiles of SAD showed a positive trend with metabolic risk factors including abdominal obesity, high blood pressure, HOMA-IR and obesity but hypertriglyceridemia, low HDL-cholesterolemia did not show significant association. In men QUICKI was significantly high. A multivariate model, adjusted for age, sex, smoking status, physical activity, heavy drinking, HOMA-IR and QUICKI, revealed a progressively increased odds ratio of metabolic syndrome, 3rd quartile (odds ratio [OR]; 9.467; 95% confidence interval [CI], 3.225 to 27.789; P < 0.001) and 4th quartile (OR, 7.253; 95% CI, 2.437 to 21.586; P < 0.001), with increasing SAD. CONCLUSION: As shown above, SAD was a strong anthropometric marker of insulin resistance, risk of metabolic syndrome and decreased insulin sensitivity in Korean adults.
