Hiccup is a common clinical symptom, and may be caused from over 100 medical origins. Generally hiccup happens temporarily, and continues only a few seconds or minutes, and is cured easily by physical methods or even by itself. But in some cases, hiccup is so refractory that patients may be tired and very troubled by it. At worst, it may cause death. Intractable hiccup is defined as hiccup persisting for more than 48 hours, and this appears in various diseases. Persistent hiccup is very difficult to treat by conventional methods. A 69-year-old man was admitted due to intractable hiccup without gastroenteral system abnormalities or peripheral nervous systemic involvement. So Paljung-san(八正散) was prescribed. The intensity and frequency of hiccup dramatically improved.

The aim of this study is to find the relationship between interictal psychiatric symptoms and seizure-related variables such as structural changes, regional interictal perfusion changes, the number of interictal epileptic discharges and the presence of accompanying generalized tonic clonic seizure(GTC). The subjects were 75 patients (47 males : mean age $28.3{\pm}7.7$) with intractable epilepsy, Interictal psychiatric symptoms were rated by Symptom Checklist-90-R(SCL-90-R). Each of 4 seizure variables was measured by MRI, $^{99m}TC-HMPAO$ SPECT and the prolonged EEG monitoring. The mean SCL-90-R subscale T-scores and the ratio of the patients with definite psychiatric symptoms(T-score > 65 at any one subscale of SCL-90-R) were compared among the groups with different seizure variables. Demographic variables and clinical variables were not statistically different among the groups with different seizure variables. The patients with right mesial temporal sclerosis had higher mean SCL-90-R scores for obsessive compulsive symptom, interpersonal sensitivity, depression, hostility and psychotic symptoms than the patients with left mesial temporal sclerosis, and they also showed higher ratio of definite psychiatric symptoms. The presence of interictal epileptic discharges was related with higher T-scores of paranoid subscale. The areas of hypoperfusion, the presence of the GTC, and other clinical seizure variables showed no significant influences on the mean SCL-90-R subscale T-scores. from these results, the authors speculated that interictal subictal epileptic dischrages may be related with psychiatric symptoms of the intractable epileptic patients, especially with right mesial temporal sclerosis.

A tyrosine kinase is an enzyme that can transfer a phosphate group from ATP to a protein in a cell. It functions as an "on" or "off" switch in many cellular functions. This study aims to show that the actions of growth factors associated with PDGFR-${\alpha}$, PDGFR-${\beta}$, VEGFR-2, c-KIT, and c-ABL, which are used in veterinary medicine, are expressed in canine intractable tumors. This study used archival cases of canine paraganglioma, gastrointestinal adenocarcinoma, hepatocellular carcinoma, and renal cell carcinoma. Tissues had been immunohistochemical analysis. The antibodies used were PDGFR-${\alpha}$, PDGFR-${\beta}$, c-kit, VEGFR-2, and c-Abl. PDGFR-${\alpha}$ was expressed only in HCC, and PDGFR-${\beta}$ was expressed in all tumors. VEGFR was also only expressed in HCC, and c-KIT has been expressed in HCC, paraganglioma, and small intestinal adenocarcinoma. c-Abl was expressed in all cancers, but was weakly expressed in paraganglioma, while more than moderately expressed in other tissues. In conclusion, this study investigated how TKIs used in human medicine can be applied to canine intractable tumors, through immunohistochemistry. The results indicate that there may be an application for TKIs in treating canine intractable tumors.

Alexander disease is a rare degenerative leukodystrophy caused by dominant mutations in glial fibrillary acidic protein (GFAP). The neonatal form of Alexander disease may manifest as frequent and intractable seizures or obstructive hydrocephalus, with rapid progression leading to severe disability or death within two years. We report a case of a 50-day-old male who presented with intractable seizures and obstructive hydrocephalus. His initial magnetic resonance imaging (MRI) suggested a tumor-like lesion in the tectal area causing obstructive hydrocephalus. Despite endoscopic third ventriculostomy and multiple administrations of antiepileptic drugs, the patient experienced intractable seizures with rapid deterioration of his clinical status. After reviewing serial brain MRI scans, Alexander disease was suspected. Subsequently, we confirmed the de novo missense mutation in GFAP (c.1096T>C, Y366H). Although the onset was slightly delayed from the neonatal period (50 days old), we concluded that the overall clinical features were consistent with the neonatal form of Alexander disease. Furthermore, we also suspected that a Y366 residue might be closely linked to the neonatal form of Alexander disease based on a literature review.

Encephalocraniocutaneous lipomatosis (ECCL) is a rare neurocutaneous syndrome that affects ectomesodermal tissues (skin, eyes, adipose tissue, and brain). The neurologic manifestations associated with ECCL are various including seizures. However, ECCL patients very rarely develop brain tumors that originate from the neuroepithelium. This is the first described case of ECCL in combination with dysembryoplastic neuroepithelial tumor (DNET) that presented with intractable seizures. A 7-year-old girl was admitted to our center because of ECCL and associated uncontrolled seizures. She was born with right anophthalmia and lipomatosis in the right temporal area and endured right temporal lipoma excision at 3 years of age. Seizures began when she was 3 years old, but did not respond to multiple antiepileptic drugs. Brain magnetic resonance (MR) imaging performed at 8 and 10 years of age revealed an interval increase of multifocal hyperintense lesions in the basal ganglia, thalamus, cerebellum, periventricular white matter, and, especially, the right temporal area. A nodular mass near the right hippocampus demonstrated the absence of N-acetylaspartate decrease on brain MR spectroscopy and mildly increased methionine uptake on brain positron emission tomography, suggesting low-grade tumor. Twenty-four-hour video electroencephalographic monitoring also indicated seizures originating from the right temporal area. Right temporal lobectomy was performed without complications, and the nodular lesion was pathologically identified as DNET. The patient has been seizure-free for 14 months since surgery. Although ECCL-associated brain tumors are very rare, careful follow-up imaging and surgical resection is recommended for patients with intractable seizures.

Helicobacter pylori (H. pyroli) infection it associated with type B gastritis, peptic uler disease, and gastric cancer. The vacuolation of cells induced by H. pylori is thought to be essential for the initiation and maintenance of gastric infection. The roles of H. pylori cytotoxin, urease, and ammonia in the vacuolation of HeLa cells were determined. H. pylori toxin induced vacuolation of HeLa cells. Korean and Japanese radishes significantly prevented the vacuolation of HeLa cells induced by H. pylori toxin. The urease activity in vacuolated cells was also decreased with Korean and Japanese radishes. H. Pylori toxin-induced vacuolation was inhibited by vacuolar type ATPase inhibitors (bafilomycin and N-ethylmaleimide). However, further investigation is required to determine the mechanisms of radish for the inhibition of vacuole formation of eukaryotic cells in response to the H. pylori toxin.

Abnormal thyroid cell proliferation has a very important role in hypothyroidism. Thyroid stimulating hormone (TSH) stimulates proliferation and maintains differentiated function in thyroid follicular cells. A functioning rat thyroid cell line (FRTL) was used to study the effect of Gamgung-tang (GGT, Glycyrrhizae Radix, black beans, Angelicae Radix and Cnidii Rhizoma) on proliferation and cAMP accumulation of thyrocytes. Proliferation of cell was assessed by DNA synthesis and incorporation of $[^3H]thymidine$ into DNA. The concentration of cAMP was measured simultaneously with growth assessment. Extract of GGT ($0.15{\sim}0.9\;mg/ml$ increased DNA synthesis in a dose-dependent manner. GGT at 0.6 (p<0.05) and 0.9 mg/ml (p<0.01) significantly increased $[^3H]thymidine$ incorporation. A comparable effect was observed with TSH. GGT also enhanced cAMP accumulation. These results indicate that GGT increases the proliferation of thyrocytes and may be considered a promising agent for the treatment of autoimmune thyroid disease.

Inflammatory cytokine, abundantly produced in Hashimoto's thyroiditis, induced Fas expression in normal thyrocytes. We determined that susceptibility to Fas-activated apoptosis could be influenced by inflammatory cytokine and investigated a potential role of Gamgung-tang (GGT, Glycyrrhizae Radix, black beans, Angelicae Radix and Cnidii Rhizoma) in the thyroid follicular cells. $IL-1\beta$ was able to induce Fas expression in normal thyrocytes. GGT inhibited $IL-1\beta-induced$ Fas expression. Thyroid follicular cells were found to undergo DNA fragmentation with the inflammatory cytokines. GGT inhibited DNA fragmentation in a dose-dependent manner. These results suggest that GGT inhibit Fas-mediated apoptosis in thyroid follicular cells, therefore, may have therapeutic potential in the treatment of autoimmune chronic thyroiditis.

The effect of protein extract from Asterina pectinifera on breast cancer chemopreventive (aromatase and cyclooxygenase-2) and metastatic (matrix metalloproteinase) enzymes was tested. Protein extract from A. pectinifera was capable of suppressing aromatase in a human placenta microsomal assay. Cyclooxygenase-2 (COX-2) activity was significantly inhibited by the protein extract from A. pectinifera at concentrations of 10, 20 and $40{\mu}g/m{\ell}$. The extract markedly reduced 12-O-tetradecanoylphorbol-13-acetate (TPA)-stimulated matrix metalloproteinase (MMP)-9 activity. These results suggest that A. pectinifera could be of therapeutic value in preventing human breast cancer.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common liver diseases. NAFLD can further progress to irreversible liver failure such as non-alcoholic steatohepatitis (NASH) fibrosis and cirrhosis. However, specific regulator of NASH-fibrosis has yet to be established. Here, we found that glutathione peroxidase 7 (GPx7) was markedly expressed in NASH fibrosis. Although GPx7 is an antioxidant enzyme protecting other organs, whether GPx7 plays a role in NASH fibrosis has yet to be studied. We found that knockdown of GPx7 in transforming growth factor-β (TGF-β) and free fatty acids (FFA)-treated LX-2 cells elevated the expression of pro-fibrotic and pro-inflammatory genes and collagen synthesis. Consistently, GPx7 overexpression in LX-2 cells led to the suppression of ROS production and reduced the expression of pro-fibrotic and pro-inflammatory genes. Further, NASH fibrosis induced by choline-deficient amino acid defined, high fat diet (CDAHFD) feeding was significantly accelerated by knockdown of GPx7, as evidenced by up-regulated liver fibrosis and inflammation compared with CDAHFD control mice. Collectively, these results suggest that GPx7 might be a novel therapeutic target to prevent the progression and development of NAFLD.
