Spermatogonial stem cells (SSCs) transmit genetic information to the next progeny in males. Thus, SSCs are a potential target for germline modifications to generate transgenic animals. In this study, we report a technique for the generation of transgenic rats by in vivo manipulation of SSCs with a high success rate. SSCs in juvenile rats were transduced in vivo with high titers of lentivirus harboring enhanced green fluorescent protein and mated with wild-type females to create founder rats. These founder rats expressed the transgene and passed on the transgene with an overall success rate of 50.0%. Subsequent generations of progeny from the founder rats both expressed and passed on the transgene. Thus, direct modification of SSCs in juvenile rats is an effective means of generating transgenic rats through the male germline. This technology could be adapted to larger animals, in which existing methods for gene modification are inadequate or inapplicable, resulting in the generation of transgenic animals in a variety of species.

Lamotrigine is an antiepileptic drug widely used to treat epileptic seizures. Using whole-cell voltage clamp recordings in combination with a fast drug application approach, we investigated the effects of lamotrigine on 5-hydroxytryptamine (5-HT)₃ receptors in NCB-20 neuroblastoma cells. Co-application of lamotrigine (1~300 µM) resulted in a concentration-dependent reduction in peak amplitude of currents induced by 3 µM of 5-HT for an IC₅₀ value of 28.2±3.6 µM with a Hill coefficient of 1.2±0.1. These peak amplitude decreases were accompanied by the rise slope reduction. In addition, 5-HT₃-mediated currents evoked by 1 mM dopamine, a partial 5-HT₃ receptor agonist, were inhibited by lamotrigine co-application. The EC₅₀ of 5-HT for 5-HT₃ receptor currents were shifted to the right by co-application of lamotrigine without a significant change of maximal effect. Currents activated by 5-HT and lamotrigine co-application in the presence of 1 min pretreatment of lamotrigine were similar to those activated by 5-HT and lamotrigine co-application alone. Moreover, subsequent application of lamotrigine in the presence of 5-HT and 5-hydroxyindole, known to attenuate 5-HT₃ receptor desensitization, inhibited 5-HT₃ receptor currents in a concentration-dependent manner. The deactivation of 5-HT₃ receptor was delayed by washing with an external solution containing lamotrigine. Lamotrigine accelerated the desensitization process of 5-HT₃ receptors. There was no voltage-dependency in the inhibitory effects of lamotrigine on the 5-HT3 receptor currents. These results indicate that lamotrigine inhibits 5-HT₃-activated currents in a competitive manner by binding to the open state of the channels and blocking channel activation or accelerating receptor desensitization.

The purpose of this study was to develop a new ginseng (Panax ginseng) flower buds extract with the high concentration of ginsenoside Rg3, Rg5, Rk1, Rh1 and F4, the Red ginseng special component. Chemical transformation from the ginseng saponin glycosides to the prosapogenin was analyzed by the HPLC. The ginseng flower buds were processed at the several treatment conditions of the ultrasonication (Oscillator 600W, Vibrator 600W) and vinegar (about 14% acidity). The result of UVGFB-480 was the butanol fraction of ginseng flower buds that had been processed with ultrasonication and vinegar for 480 minutes gained the highest amount of ginsenoside Rg5 (3.548%), Rh1 (2.037%), Rk1 (1.821%), Rg3 (1.580%) and F4 (1.535%). The ginsenoside Rg5 of UVGFB-480 was found to contain 14.3 times as high as ginseng flower buds extracts (GFB, 0.249%).

Several cases of acute necrotizing encephalopathy (ANE) with influenza A (H1N1) have been reported to date. The prognosis of ANE associated with H1N1 is variable; some cases resulted in severe neurologic complication, whereas other cases were fatal. Reports mostly focused on the diagnosis of ANE with H1N1 infection, rather than functional recovery. We report a case of ANE with H1N1 infection in a 4-year-old Korean girl who rapidly developed fever, seizure, and altered mentality, as well as had neurologic sequelae of ataxia, intentional tremor, strabismus, and dysarthria. Brain magnetic resonance imaging showed lesions in the bilateral thalami, pons, and left basal ganglia. To our knowledge, this is the first report of ANE caused by H1N1 infection and its long-term functional recovery in Korea.

OBJECTIVE: To investigate the reliability of inspection-based classification of sagittal gait patterns in children with bilateral spastic cerebral palsy (CP). METHOD: Video clip recordings of gait patterns and sagittal kinematic data obtained by a computerized motion analysis system from 91 patients with bilateral spastic CP were reviewed. The abnormal gait patterns were classified into 4 groups using the method described by Rodda et al. Visual observation-based classification (visual classification) was compared with classification by 3D analysis-based methods (3D classification). The reliabilities of visual classifications made by an experienced physician and a trainee physician were analyzed. RESULTS: The consistency of inspection-based gait classification using kinematic data analysis was demonstrated by an experienced physician (Kappa coefficient (k)=0.67, p<0.001). However, the consistency was low for the trainee physician (k=0.37, p<0.001). Group III (apparent equinus) was commonly confused with group IV (crouch gait) by the trainee physician, resulting in lower agreement for those two evaluation groups than for other patterns. Video observation showed low reliability in comparisons made between the experienced and the trainee physician (k=0.37, p<0.001). CONCLUSION: There was substantial agreement of gait classification between video observation and kinematic data analysis by the experienced physician, but not by the trainee physician. Low reliability was also demonstrated for inspection-based gait classification.

The striatum receives glutamatergic afferents from the cortex and thalamus, and these synaptic transmissions are mediated by alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA) and N-methyl-D-aspartate (NMDA) receptors. The purpose of this study was to characterize glutamate receptors by analyzing NMDA/AMPA ratio and rectification of AMPA and NMDA excitatory postsynaptic currents (EPSCs) using a whole-cell voltage-clamp method in the dorsal striatum. Receptor antagonists were used to isolate receptor or subunit specific EPSC, such as (DL)-2-amino-5-phosphonovaleric acid (APV), an NMDA receptor antagonist, ifenprodil, an NR2B antagonist, CNQX, an AMPA receptor antagonist and IEM-1460, a GluR2-lacking AMPA receptor blocker. AMPA and NMDA EPSCs were recorded at -70 and +40 mV, respectively. Rectification index was calculated by current ratio of EPSCs between +50 and -50 mV. NMDA/AMPA ratio was 0.20+/-0.05, AMPA receptor ratio of GluR2-lacking/GluR2-containing subunit was 0.26+/-0.05 and NMDA receptor ratio of NR2B/NR2A subunit was 0.32+/-0.03. The rectification index (control 2.39+/-0.27) was decreased in the presence of both APV and combination of APV and IEM-1460 (1.02+/-0.11 and 0.93+/-0.09, respectively). These results suggest that the major components of the striatal glutamate receptors are GluR2-containing AMPA receptors and NR2A-containing NMDA receptors. Our results may provide useful information for corticostriatal synaptic transmission and plasticity studies.

The effect of forskolin on corticostriatal synaptic transmission was examined by recording excitatory postsynaptic currents (EPSCs) in rat brain slices using the whole-cell voltage-clamp technique. Forskolin produced a dose-dependent increase of corticostriatal EPSCs (1, 3, 10, and 30micrometer) immediately after its treatment, and the increase at 10 and 30micrometer was maintained even after its washout. When the brain slices were pre-treated with (DL)-2-amino-5-phosphonovaleric acid (AP-V, 100micrometer), an NMDA receptor antagonist, the acute effect of forskolin (10micrometer) was blocked. However, after washout of forskolin, an increase of corticostriatal EPSCs was still observed even in the presence of AP-V. When KT 5720 (5micrometer), a protein kinase A (PKA) inhibitor, was applied through the patch pipette, forskolin (10micrometer) increased corticostriatal EPSCs, but this increase was not maintained. When forskolin was applied together with AP-V and KT 5720, both the increase and maintenance of the corticostriatal EPSCs were blocked. These results suggest that forskolin activates both NMDA receptors and PKA, however, in a different manner.

Flavonoids have been shown to affect calcium signaling in neurons. However, there are no reports on the effect of apigenin on glutamate-induced calcium signaling in neurons. We investigated whether apigenin affects glutamate-induced increase of free intracellular Ca2+concentration ([Ca2+]i) in cultured rat hippocampal neurons, using fura-2-based digital calcium imaging and microfluorimetry. The hippocampal neurons were used between 10 and 13 days in culture from embryonic day 18 rats. Pretreatment of the cells with apigenin (1micrometerto 100micrometer for 5 min inhibited glutamate (100 micrometer 1 min) induced [Ca2+]i increase, concentration-dependently. Pretreatment with apigenin (30micrometer for 5 min significantly decreased the [Ca2+]i responses induced by two ionotropic glutamate receptor agonists, alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic (AMPA, 10 micrometer 1 min) and N-methyl-D-aspartate (NMDA, 100 micrometer 1 min), and significantly inhibited the AMPA-induced peak currents. Treatment with apigenin also significantly inhibited the [Ca2+]i response induced by 50 mM KCl solution, decreased the [Ca2+]i responses induced by the metabotropic glutamate receptor agonist, (S)-3,5-dihydroxyphenylglycine (DHPG, 100micrometer 90 s), and inhibited the caffeine (10 mM, 2 min)-induced [Ca2+]i responses. Furthermore, treatment with apigenin (30micrometer significantly inhibited the amplitude and frequency of 0.1 mM [Mg2+o-induced [Ca2+]i spikes. These data together suggest that apigenin inhibits glutamate-induced calcium signaling in cultured rat hippocampal neurons.

Fluoxetine, widely used for the treatment of depression, is known to be a selective serotonin reuptake inhibitor (SSRI), however, there are also reports that fluoxetine has direct effects on several receptors. Employing whole-cell patch clamp techniques in rat brain slice, we studied the effects of fluoxetine on corticostriatal synaptic transmission by measuring the change in spontaneous excitatory postsynaptic currents (sEPSC). Acute treatment of rat brain slice with fluoxetine (10microM) significantly decreased the amplitude of sEPSC (84.1+/-3.3%, n=7), but did not alter its frequency (99.1+/-4.7%, n=7). Serotonin (10microM) also significantly decreased the amplitude (81.2+/-3.9%, n=4) of sEPSC, but did not affect its frequency (105.8+/-8.0, n=4). The effect of fluoxetine was found to have the same trend as that of serotonin. We also found that the inhibitory effect of fluoxetine on sEPSC amplitude (93.0+/-1.9%, n=8) was significantly blocked, but not serotonin (84.3+/-1.6%, n=4), when the brain slice was incubated with p-chloroamphetamine (10microM), which depletes serotonin from the axon terminals and blocks its reuptake. These results suggest that fluoxetine inhibits corticostriatal synaptic transmission through postsynaptic, and that these effects are exerted through both serotonin dependent and independent mechanism.

The effects of ethanol on corticostriatal synaptic transmission were examined, using extracellular recording and analysis of population spike amplitudes in rat brain slices, to study how acute ethanol intoxication impairs striatal function. Ethanol caused a decrease in population spike amplitudes in a dose dependent manner (50~200 mM). Pretreatment with picrotoxin, a gamma-amino butyric acid (GABA)A receptor antagonist, increased the population spikes but ethanol (100 mM) was still effective in decreasing the population spikes under this condition. In the presence of (DL)-2-amino-5-phosphonovaleric acid (APV), N-methyl-D-aspartate (NMDA) receptor antagonist, the inhibitory action of ethanol on population spikes was not shown. These results suggest that ethanol inhibits the glutamatergic corticostriatal synaptic transmission through blockade of NMDA receptors.

Striatum has important roles in motor control, habitual learning and memory. It receives glutamatergic inputs from neocortex and thalamus, and dopaminergic inputs from substantia nigra. We examined effects of dopamine (DA) on the corticostriatal synaptic transmission using in vitro extracellular recording technique in rat brain corticostriatal slices. Synaptic responses were elicited by stimulation of cortical glutamatergic inputs on the corpus callosum and recorded in the dorsal striatum. Corticostriatal population spike (PS) amplitudes were decreased (39.4+/-7.9%) by the application of 100microM DA. We applied receptor subtype specific agonists and antagonists and characterized the modulation of corticostriatal synaptic transmission by different DA receptor subtypes. D2 receptor agonist (quinpirole), antagonist (sulpiride), and D1 receptor antagonist (SKF 83566), but not D1 receptor agonist (SKF 38393), induced significantly the reduction of striatal PS. Pretreatment neither with SKF 83566 nor sulpiride significantly affected corticostriatal synaptic inhibition by DA. However, the inhibition of DA was completely blocked by pretreatment with mixed solution of both SKF 83566 and sulpiride. These results suggest that DA inhibits corticostriatal synaptic transmission through both D1 and D2 receptors in concert with each other.

Striatum is involved in the control of movement and habitual memory. It receives glutamatergic input from wide area of the cerebral cortex as well as an extensive serotonergic (5-hydroxytryptamine, 5-HT) input from the raphe nuclei. In our study, the effects of 5-HT on synaptic transmission were studied in the rat corticostriatal brain slice using in vitro whole-cell recording technique. 5-HT inhibited the amplitude as well as frequency of spontaneous excitatory postsynaptic currents (sEPSC) significantly, and neither gamma-aminobutyric acid (GABA) A receptor antagonist bicuculline (BIC), nor N-methyl-D-aspartate (NMDA) receptor antagonist, DL-2-amino-5-phosphonovaleric acid (AP-V) could block the effect of 5-HT. In the presence non-NMDA receptor antagonist, 2, 3-dioxo-6-nitro-1, 2, 3, 4-tetrahydrobenxo[f] quinoxaline-7-sulfonamide (NBQX), the inhibitory effect of 5-HT was blocked. We also figured out that 5-HT change the channel kinetics of the sEPSC. There was a significant increase in the rise time during the 5-HT application. Our results suggest that 5-HT has an effect on both pre- and postsynaptic site with decreasing neurotransmitter release probability of glutamate and decreasing the sensitivity to glutamate by increasing the rise time of non-NMDA receptor mediated synaptic transmission in the corticostriatal synapses.

Striatum plays a crucial role in the movement control and habitual learning. It receives an information from wide area of cerebral cortex as well as an extensive serotonergic (5-hydroxytryptamine, 5-HT) input from raphe nuclei. In the present study, the effects of 5-HT to modulate synaptic transmission were studied in the rat corticostriatal brain slice using in vitro extracellular recording technique. Synaptic responses were evoked by stimulation of cortical glutamatergic inputs on the corpus callosum and recorded in the dorsal striatum. 5-HT reversibly inhibited coticostriatal glutamatergic synaptic transmission in a dose-dependent fashion (5, 10, 50, and 100 microM), maximally reducing in the corticostriatal population spike (PS) amplitude to 40.1+/-5.0% at a concentration of 50 microM 5-HT. PSs mediated by non-NMDA glutamate receptors, which were isolated by bath application of the NMDA receptor antagonist, d, l-2-amino-5-phospohonovaleric acid (AP-V), were decreased by application of 50 microM 5-HT. However, PSs mediated by NMDA receptors, that were activated by application of zero Mg2+ aCSF, were not significantly affected by 50 microM 5-HT. To test whether the corticostriatal synaptic inhibitions by 5-HT might involve a change in the probability of neurotransmitter release from presynaptic nerve terminals, we measured the paired-pulse ratio (PPR) evoked by 2 identical pulses (50 ms interpulse interval), and found that PPR was increased (33.4+/-5.2%) by 5-HT, reflecting decreased neurotransmitter releasing probability. These results suggest that 5-HT may decrease neurotransmitter release probability of glutamatergic corticostriatal synapse and may be able to selectively decrease non-NMDA glutamate receptor-mediated synaptic transmission.

PURPOSE: In South Korea, as growing the need of psychological support in disaster situation psychological assessment on stress after disaster is important to find out the factors affecting coping, and to plan intervention in the community. METHOD: The volunteers of Korea Redcross who live around K city, and the research team visited all homes at Jirye town, one of the high-impact area, 4 month after the typhoon. One of the family members who is over 18 years old, answered the self-report questionnaire composed of disaster experience, damage, exposure to traumatic event, and posttraumatic stress with IES-K (Impact of Event Scale-korea) He also, described his family members symptom related to re-experiencing, hyper-arousal, and avoidance. Six hundreds households were surveyed. RESULT: The prevalence of moderate to severe PTSD symptom was 36% of the subjects. The severity of PTSD was affected by gender, economic status and affected by damaged property, physical injury, worsening existing disease, getting infectious disease, amount of experienced traumatic event before disaster, warning, taking shelter, and subjects revealed differences in somatization as severity of PTSD. According to the description, community members had re-experiencing, hyper-arousal and avoidance. CONCLUSION: At a rural area, South Korea, community members have suffered from psychological distress after disaster. So psychological interventions are required as affecting factors and also to plan for warning and shelter in disaster situation is needed for preventing PTSD.

OBJECTIVE: The purpose of this study is to elucidate the causes of the ischemic complication after surgery for posterior communicating artery aneurysm and to represent the ways of preventing or minimizing this specific complication. METHODS: Between January 2000 and December 2001, fifty one patients were treated for the posterior communicating artery aneurysm. The medical records and neuroimaging studies of the patients were reviewed retrospectively. RESULTS: Among the series of 51 surgically treated patients, the authors experienced 6 cases of ischemic complication involving 3 thalamus, 2 posterior cerebral artery territory and 1 periventircular white matter. Four patients were treated by aneurysmal neck clipping and one patient with fusiform aneurysm and one patient with infundibulum at internal carotid-posterior communicating artery junction by parent artery trapping and parent artery occlusion, respectively. In 4 cases with aneurysmal clipping the authors could not confirm the patency of the parent artery or posterior communicating artery during operation by the obstacle such as internal carotid artery and/or aneurysmal dome. The neurological deficits developed postoperatively were improved or subside during hospital courses and all six patients showed good outcome(Glasgow Outcome Scale score V) at discharge. CONCLUSION: In most cases the posterior communicating artery itself can be separated from the neck of the aneurysm and thereby preserved to avoid a significant infarct in the thalamus and occipital lobe.

BACKGROUND: The purpose of this study was to find an independent relationship between waist circumference/waist-to-hip ratio which estimates abdominal fat and fasting insulin/atherogenic index which is a predictor of coronary heart disease in obese women. METHODS: The subjects were 80 obese (BMI > or = 25 kg/m2) women. Whole body fat was estimated by body fat mass, % body fat using bioelectrical impedence, and by BMI. Abdominal fat was measured by waist circumference (WC) and waist-to-hip ratio. Fasting insulin was examined and atherogenic index was defined asthe ratio of serum total cholesterol to HDL-cholesterol. Independent association between abdominal fat and insulin/AI was analyzed using partial correlation, multiple regression and Hotelling t-test. RESULTS: Among subjects, 85.7% of obese women had WC greater or equal to 80 cm. The mean BMI was 30.3 kg/m2. The partial correlations between whole body fat and insulin/AI were not significantly different from the partial correlations between abdominal fat and insulin/AI. When age and height were adjusted, partial correlations between abdominal fat and insulin were 0.38 and 0.39. The partial correlations were reduced to 0.15-0.29 after further adjusting for whole body fat. Age and height-adjusted partial correlations between abdominal fat and AI were 0.34 and 0.36. The partial correlations were reduced to 0.11-0.17 when whole body fat was additionally adjusted. Whole body fat explained 9.9-13.7% for variability of insulin; abdominal fat explained 14.2% and 15.9%. Whole body fat explained 12.5-12.8% for variability of AI and abdominal fat explained 11.9%. CONCLUSION: Most of the obese women showed abdominal obesity. Abdominal fat did not seem to be independently associated with fasting insulin and atherogenic index.

Dandy-Walker syndrome indicates the association of cystic dilatation of fourth ventricle, dysgenesis of the cerebellar vermis and a high position of the tentorium. Dandy-Walker syndrome has an estimated prevalence of about 1 in 30,000 births and is found in 4% to 12% of all cases of infantile hydrocephalus. And trisomy 18 was present in 4.8% of the Dandy-Walker syndrome. Trisomy 18 is a chromosomal aneuploid, which results in multiple severe structural abnormalities that mostly involve the heart, extremities, face, and brain. We experienced a case of Edward syndrome associated with Dandy-Walker syndrome. She did not want to terminate her pregnancy. So, we reviewed a Edward syndrome with Dandy-Walker syndrome and presented the final result in full term delivery.

OBJECTIVES: Although pregnancy in women who are 35 years old or more is considered a high risk pregnancy, it has occurred more frequently in recent years. The aim of our study was to evaluate the course of delivery and perinatal outcomes in women who are 35 years old or more. METHOD: We have compared 765 cases of the elderly gravida over the age of 35 at the department of Obstetrics and Gynecology, Mokpo, Catholic Hospital, from January 1, 1997 to December 31, 1999, with 800 cases of randomly chosen young pregnant women during the same period. RESULTS: There were 765 cases of the elderly gravida among total 8285 deliveries and the incidence of the elderly gravida for 3 years was 9.2%. The rate of elderly gravida was increased from 8.2% in 1997 to 10.0% in 1999. 46.9% were in the age group of 35 to 36 years. The incidence of primigravida was 13.9%. 93.6% of total cases was vertex presentation breech presentation was 5.2%, and transverse lie was 1.2%. The percentage of preterm pregnancy was 9.5% in elderly gravida, and 4.0% in control group. post-term pregnancy was 2.0% in elderly gravida, and 1.0% in control group.The rate of cesarean section was 48.8%, compared with 26.7% in the control group. Among the indications of cesarean section, the highest incidence was previous cesarean section (40.0%) and elderly primigravida (18.0%), fetal distress (10.7%), cephalopelvic disproportion (7.5%), and abnormal presentation (6.7%). Concerning the prenatal complications, the incidence of hypertensive disorder was 4.3%, and 2.6% in control group. The incidence of low birth weight and macrosomia were 8.9%, 8.8% in elderly gravida, and 5.5%, and 9.3% in control group. The incidence of IUFD was 3.1% in elderly gravida, and 0.63% in control group. Male-to-female sex ratios were 1.12:1 in elderly gravida, 1:1.16 in elderly primigravida, 1.17:1 in elderly multi gravida, and 1.20:1 in control group. CONCLUSION: The rate of elderly gravida increased in recent years, and the cesarean rate was higher compared with the control group. But there was no difference in perinatal mortality. The reasons for increasing rate of cesarean delivery may be due to physician and patient concern over pregnancy outcome in older women. Therefore it is necessary to exert more attention to pregnancies in those over the age of 35.
