To evaluate the meaning of anti-HCV detection in patients treated with IVIG, serum levels of aspartate aminotranstferase(AST), alanine aminotransterase(ALT), HCV Ab titer were measured after treatment with IVIG in 36 patients diagnised of Kawasaki disease or neonatal sepsis. Also polymerase chain reaction (PCR) for the detection of HCV was done in 8 patients with persistent HCV Ab positivity at 3 months after IVIG treatment. The results were as follows 1) HCV Ab was positive in all 36 patients at 1 week after IVIG treatment, but in only 8 cases it was positive at 3 months after IVIG treatment. 2) AST, ALT were elevated in 9 cases at 1 week after IVIG treatment, but they were normalized in all cases at 3 months after IVIG treatment. 3) PCR for the detection of HCV was done in 8 patients with persistent HCV Ab positivity at 3 months after IVIG treatment, but HCV was not isolated in any cases. These results suggested that detection of anti-HCV was merely transitory phenominon of HCV Ab transmission, did not show any evidence of HCV infection due to HCV transmission.

The adult worm and plerocercoid larva(sparganum) of Diphyllobothrium mansoni and Moniezia expansa employed in this experiment. The adult worms were divided into three portions, i.e. immature, mature and gravid proglottids, and each proglottids were incubated in 50 cc or 250 cc volume of special incubation flasks with incubation medium consisting of 10 cc of 25 cc of Krebs-Ringer phosphate buffer (pH 7.4). The incubation medium was added C(14)-acetate and non-radioactive carrier Na-acetate so as to contain acetate concentration of 50 mg per cent. The worms were allowed to incubate for 5 hours in the Dubnoff metabolic shaking incubator at 38 C. After incubation period, the lactate and pyruvate appearance rate, total CO(2) production tate, the turnover rates were employed as pervious report(Seo et al., 1965). The quantitative analysis of C(14)-acetate utilized by the adult worm and plerocercoid larva of D. mansoni and M. expansa were compared and discussed in this report. According to these data of the experiment, it is impressed that the fatty acid such as acetate may play a role of major part of their metabolism in the adult worm and plerocercoid larva of D. mansoni , whereas minor part of acetate participated in the metabolism by M. expansa.

The adult trematodes, Fasciola hepatica, Eurytrema pancreaticum and Paramphistomum cervi, employed in this experiment were obtained from the cattle slaughtered at the local abbatoir. The worms selected and washed several times in normal sterilized saline solution. Each about ten of intact F. hepatica, fourty of E. pancreaticum, and twenty of P. cervi were incubated in 50 cc volume of special incubation flasks with incubation medium consisting of 10 cc. of Krebs-Ringer phosphate buffer(pH 7.4) The incubation medium was added C(14)-1-acetate and non-radioactive carrier Na-acetate so as to contain acetate concentration of 50 mg per cent . The worms were allowed to incubate for 5 hours in the Dubnoff metabolic shaking incubator at 38 C. After incubation period, respiratory CO(2) samples from central well of incubation flask were analysed for total CO(2) production rate and their specific activity of respiratory CO(2). The lactate and pyruvate appearance rates were determined by analyzing the lactate and pyruvate concentration in a medium after incubation. The glycogen samples isolated from worms were analyzed for the tissue concentration and their radioactivities in order to determine the turnover rate of glycogen pool. Radioactivities of these series of experiments were counted by an endwindow Geiger-Muller counter as an infinitely thin samples. The quantitative analysis of C(14)-acetate utilized by F. hepatica, E. pancreaticum and P. cervi were compared and discussed in this report. According to these data of the experiment, it is suggested that the fatty acid such as acetate may play a part of their oxidative process into the respiratory CO2 and the synthetic process into glycogen in the above species of trematodes.

To examine the effect of obesity on volume perception according to size and color of rice bowl, we divided female college students into a normal weight group (<30% fat mass, n=100) and obese group (> or =30% fat mass, n=83) and then measured perceived volume of rice bowls of various sizes (general size; 350 ml vs. small size; 188 ml) and color (yellow, white, blue, and black) containing the same amount of cooked white rice (210 g). Normal weight group perceived that the general rice bowl contained significantly more cooked white rice compared to the small rice bowl. In contrast, the obese group perceived that the general rice bowl contained significantly less cooked white rice than the small rice bowl. The estimated variance in perceived volume of both bowls was significantly bigger in the obese group compared to the normal group. There were no differences in perceived volume among any of the subjects (both normal and obese groups) according to rice bowl color. However, the estimated variance in perceived volume in the obese group was significantly larger than that in the normal group for all of the rice bowls. In conclusion, rice bowl size and color might affect volume perception, and volume perception in obese people may be different from that of normal weight people.

PURPOSE: Dental CT software program can provide reformatted cross-sectional and panoramic images that cannot be obtained with conventional axial & direct coronal CT scan. The purpose of this study is to describe the method of the technique and to identify the precise anatomy of jaw. MATERIALS AND METHODS:We evaluated 13 mandibles & 7 maxillae of 15 subjects without bony disease who were being considered for endosseous dental implants. Reformatted images obtained by the use of bone algorithm performed on GE HiSpeed Advantage CT scanner were retrospectively reviewed for detailed anatomy of RESULTS: Anatomy related to neurovascular bundle(mandibular foramen, inferior alveolar canal, mental foramen, canal for incisive artery, nutrient canal, lingual foramen and mylohyoid groove), muscular insertion(mylohyoid line, superior & inferior genial tubercle and digastric fossa) and other anatomy(submandibular fossa, sublingual fossa, contour of alveolar process, oblique line, retromolar fossa, temporal crest & retromolar triangle) were well delineated in mandible. In maxilla, anatomy related to neurovascular bundle(greater palatine foramen & groove, nasopalatine canal and incisive foramen) and other anatomy(alveolar process, maxillary sinus & nasal fossa) were also well delineated. CONCLUSION: Reformatted images using dental CT software program provided excellent delineation of the jaw anatomy. Therefore, dental CT noftware program can play an important role in the preoperative assessment of mandible and maxilla for dental implants and other surgical conditions.

VACTERL association is a disease with multiple congenital anomalies of the vertebrae, anus, cardia, tracheoesophageal(TE) fistula, renal and limb. This disease is derived from VATER anomaly, accompanied by cardiac and limb anomalies. We experienced a case of a 1-day-old boy with anal atresia, who represented multiple anomalies during hospital course. The multiple anomalies were hemivertebra, anal atresia, complex heart disease(coarctation of aorta, secundum aterial septal defect, patent ductus arteriosus), horseshoe kidney, tracheal stenosis, tracheal bronchus and left upper lung agenesis. Because both trachea and esophagus arise from fetal foregut, tracheal or pulmonary anomalies may be developed in VACTERL association instead of TE fistula. VACTERL association with tracheal anomalies, such as tracheal stenosis and tracheal bronchus or pulmonary agenesis, have been reported in foreign scientific society reports. But a case of VACTERL association with both tracheal bronchus and pulmonary agenesis has not reported yet. So we report this case with a brief review of related literature and suggest the consideration of possibility of tracheal or pulmonary anomaly in VACTERL association without TE fistula.

BACKGROUND AND OBJECTIVES: Vestibular evoked myogenic potentials (VEMP) have become a good diagnostic tool to evaluate the integrity of the vestibulocollic reflex. To investigate the standard recording of VEMP response in normal hearing subjects, the authors studied the effects of test positions and different acoustic stimulations on the VEMP. SUBJECTS AND METHOD: We performed VEMP on both ears of thirty normal hearing volunteers. Three acoustic stimulations (clicks and 500 Hz and 1,000 Hz short tone bursts) and four test positions were presented alternately to evoke VEMP. The latencies of peak p13 and n23, p13n23 interpeak latency (IPL) and amplitude were measured by EMG equipment and compared by statistical program. We also made up questions for the compliance of the test positions. RESULTS: The effects of test positions p13 latency had no significant difference on all test positions except between test position 2 and 4, n23 latency and p13n23 IPL had shortest waveform on test position 2, p13n23 amplitude had the largest waveform in test position 4. Acoustic stimulations on all test positions were influenced that clicks had shorter waveform about 2-3 ms than STBs on p13 latency and n23 latency, STBs had larger waveform than clicks on p13n23 amplitude. And the compliance of the test positions exhibited highest comfort in test position 1. CONCLUSION: Test position 1 had higher VEMP response rates and compliance, 500 Hz STB had a largest p13n23 amplitude. Therefore we recommend that the ideal conditions were position 1 and 500 Hz STB for acoustic stimulations to evoke VEMP.

Poria cocos is a well-known traditional Chinese traditional medicine (TCM) that grows around roots of pine trees in China, Korea, Japan, and North America. Poria cocos has been used in Asian countries to treat insomnia as either a single herb or part of an herbal formula. In a previous experiment, pachymic acid (PA), an active constituent of Poria cocos ethanol extract (PCE), increased pentobarbital-induced sleeping behaviors. The aim of this experiment was to evaluate whether or not PCE and PA modulate sleep architectures in rats as well as whether or not their effects are mediated through GABA(A)-ergic transmission. PCE and PA were orally administered to individual rats 7 days after surgical implantation of a transmitter, and sleep architectures were recorded by Telemetric Cortical encephalogram (EEG) upon oral administration of test drugs. PCE and PA increased total sleep time and non-rapid eye movement (NREM) sleep as well as reduced numbers of sleep/wake cycles recorded by EEG. Furthermore, PCE increased intracellular chloride levels, GAD65/67 protein levels, and alpha-, beta-, and gamma-subunits of GABA(A) receptors in primary cultured hypothalamic neuronal cells. These data suggest that PCE modulates sleep architectures via activation of GABA(A)-ergic systems. Further, as PA is an active component of PCE, they may have the same pharmacological effects.

Radiation-induced epithelial proliferation in the urinary bladder mimicking urothelial carcinoma has received only a little attention in the literature. Herein, we describe two cases of radiation-induced epithelial proliferative changes, which mimicked invasive urothelial carcinoma. Cystoscopy revealed bullous or edematous mucosal changes with multiple hemorrhagic foci. Microscopically, we observed inverted epithelial proliferation, forming nests and cords extending into the lamina propria. The epithelial cells in these nests and cords exhibited enlarged, hyperchromatic and pleomorphic nuclei, closely mimicking the infiltrative growth of urothelial carcinoma. However, the presence of radiation-induced changes was validated by the observation of abundant vacuolated cytoplasm, normal or slightly increased nuclear to cytoplasmic ratios, the absence of mitotic activity, dilated blood vessels containing frequent fibrin thrombi, scattered atypical fibroblasts, and the patients' previous history of radiation treatment. Radiation-induced changes should be always included in differential diagnoses of proliferative epithelial lesions in the urinary bladder and a pertinent clinical history of radiotherapy should be searched.

In the previous experiments, we reported that ethanol extract of Gastrodiae Rhizoma, the dried tuber of Gastrodia ElataBlume (Orchidaceae) increased pentobarbital-induced sleeping behaviors. These experiments were undertaken to know whether 4-hydroxybenzaldehyde (4-HBD), is one of the major compounds of Gastrodiae Rhizoma increases pentobarbital-induced sleeping behaviors and changes sleep architectures via activating GABA(A)-ergic systems in rodents. 4-HBD decreased locomotor activity in mice. 4-HBD increased total sleep time, and decreased of sleep onset by pentobarbital (28 mg/kg and 40 mg/kg). 4-HBD showed synergistic effects with muscimol (a GABA(A) receptor agonist), shortening sleep onset and enhancing sleep time on pentobarbital-induced sleeping behaviors. On the other hand, 4-HBD (200 mg/kg, p.o.) itself significantly inhibited the counts of sleep-wake cycles, and prolonged total sleep time and non-rapid eye movement (NREM) in rats. Moreover, 4-HBD increased intracellular Cl- levels in the primary cultured cerebellar cells. The protein levels of glutamic acid decarboxylase (GAD) and GABA(A) receptors subunits were over-expressed by 4-HBD. Consequently, these results demonstrate that 4-HBD increased NREM sleep as well as sleeping behaviors via the activation of GABA(A)-ergic systems in rodents.
