We investigated the effects of chronic administration of different extracts of ginger rhizome [pet ether extract (PE); toluene fraction (TF) of pet ether extract] on anxiety models: the elevated T-maze (ETM) (for inhibitory avoidance and escape measurements) and the open field test. Ondansetron (1 mg/kg), FE (10, 30 &100 mg/kg) and TF (10 & 30 mg/kg) were administered orally for 15 days. On the $14^{th}$ day mice were previously exposed for 30 min to one of the open arms of the T-maze, 24 h before the test. On $15^{th}$ day mice had two exposures to the enclosed and open arm of the ETM followed by exposure to the open field apparatus. The number of line crossings in the apparatus was used to assess locomotor changes. Cumulative Concentration Response Curve of 5-HT was plotted using rat fundus which were pretreated in a similar way. Treatment with Ondansetron (1 mg/kg), PE (100 mg/kg), TF (10 mg/kg) and TF (30 mg/kg) significantly (P<0.05) impaired inhibitory avoidance performance but did not impair escape latency. Concentration response curve of 5-HT was shifted towards the right with suppression of maxima in rats treated with PE and TF. The results suggest that PE and TF of Ginger rhizome exerts anxiolytic like behaviour in a specific subset of defensive behaviour, particularly those related to generalized anxiety disorder.

The general and some other pharmacological actions of growth hormone without N-terminal methionine(rhGH) were investigated in animals. The hormone had no influences on the central nervous system and on body temperature at a high oral dose of 40 IU/kg in animals. It had neither analgesic nor antiepileptic actions at the high doses. In the isolated ileum and trachea of guinea-pig and isolated stomach fundus and uterus of rat, it showed neither contractive nor relaxing effects at a concentration of $1{\times}10^{-3}\;IU/ml$ in bath, and no inhibitory action at a dose of $1{\times}10^{-3}\;IU/ml$ against the contractions produced by histamine ($5{\times}10^{-5}\;g/ml$), serotonin($1{\times}10^{-5}\;g/ml$), acetylcholine($1{\times}10^{-5}\;g/ml$) and oxytocin($5{\times}10^{-3}\;IU/ml$). Furthermore, the intravenous injection of 20 IU/kg rhGH had no influences on the normal blood pressure and respiration in rabbits. These negative results in pharmacological profile are thought that the hormone may not elicit serious side effects. On the other hand, the rhGH exhibited a weak inhibitory action of glucose tolerance in normal rats, significantly lowered the blood glucose contents in adrenalectomized rats 20 min after i.v. administration of 80 IU/kg, and showed a significant inhibitory effect on in vitro glycerol release in epinephrine-stimulated epididymal fat pad segments of rats.

A 6-year-old female Pekingese dog, weighing 3.85 kg was presented with regurgitation, ptyalism, weight loss and anorexia. The dog was cachexic and severely dehydrated. Physical examination of the dog confirmed upper respiratory noise, which was classified as a stridor most apparent on inspiration, respiratory effort with stenotic nares. Upper respiratory signs were thought to be caused by brachycephalic syndrome. On the lateral thoracic radiograph, the caudal one third of the esophagus was visible as a soft tissue band. CT revealed oval-shaped, soft tissue attenuating mass in size of $2.3{\times}1.0{\times}1.1cm$ arising from caudal one third of the esophagus. The mass was protruding from esophageal wall to lumen and irregular margined with heterogenous contrast enhancement. The wall of cardia and fundus was focally thickened. Gastric lymph node was enlarged with contrast enhancing. On histopathologic examination, esophageal mass was confirmed as papillary adenocarcinoma, and the gastric sample showed the same result. In human, adenocarcinoma commonly occur in esophagus and cardia, but it has not been commonly reported in veterinary medicine. This report described computed tomographic features of adenocarcinoma of the esophagocardia region in a Pekingese dog with brachycephalic syndrome.

Background: Treatment of Helicobacter pylori (H. pylori) decreases the prevalence of gastric cancer, and may inhibit gastric precancerous lesions progression into gastric cancer. The aim of this study was to determine the effect of treatment on subsequent gastric precancerous lesion development. Materials and Methods: We prospectively studied 27 patients who had low grade dysplasia at the time of enrollment, in addition to dysplasia atrophic gastritis and intestinal metaplasia observed in all patients. All were prescribed quadruple therapy to treat H. Pylori infection for 10 days. Patients underwent endoscopy with biopsy at enrollment and then at follow up two years later. Biopsy samples included five biopsies from the antrum of lesser curvature, antrum of greater curvature, angularis, body of stomach and fundus. Results of these biopsies were compared before and after treatment. Results: Overall, the successful eradication rate after two years was 15/27 (55.6%). After antibiotic therapy, the number of patients with low grade dysplasia decreased significantly (p=0.03), also with reduction of the atrophic lesions (p=0.01), but not metaplasia. Conclusions: Treatment of H. pylori likely is an effective therapy in preventing the development of subsequent gastric premalignant lesions.

Background: Dysplasia and adenocarcinoma developing in Barrett's esophagus (BE) are not always endoscopically identifiable. Molecular markers are needed for early recognition of these focal lesions and to identify patients at increased risk of developing adenocarcinoma. The aim of the current study was to correlate increased telomerase activity (TA) with dysplasia and adenocarcinoma occurring in the setting of BE. Materials and Methods: Esophageal mucosal biopsies were obtained from patients (N=62) who had pathologically verified BE at esophagogastroduodenoscopy (EGD). Mucosal biopsies were also obtained from the gastric fundus as controls. Based on histopathology, patients were divided into three groups: 1) BE without dysplasia (n=24); 2) BE with dysplasia (both high grade and low grade, n=13); and 3) BE with adenocarcinoma (n=25). TA was measured by a PCR-based assay (TRAPeze$^{(R)}$ ELISA Telomerase Detection Kit). Statistical analyses were performed using one-way ANOVA and post-hoc Bonferroni testing. Results: TA was significantly higher in biopsies of BE with dyplasia and BE with adenocarcinoma than in BE without dysplasia. Subgroup analyses did not reveal any significant correlations between TA and patient age, length of BE, or presence of gastritis. Conclusions: Telomerase activity in esophageal mucosal biopsies of BE may constitute a useful biomarker for the early detection of esophageal dysplasia and adenocarcinoma.

Toxoplasma gondii is a zoonotic parasite resulting in human infections and one of the infectious pathogens leading to uveitis and retinochoroiditis. The present study was performed to assess T. gondii infection in 20 ocular patients with chronic irregular recurrent uveitis (20 aqueous humor and 20 peripheral blood samples) using PCR. All samples were analyzed by nested PCR targeting a specific B1 gene of T. gondii. The PCR-positive rate was 25% (5/20), including 5% (1) in blood samples, 25% (5) in aqueous humor samples, and 5% (1) in both sample types. A molecular screening test for T. gondii infection in ocular patients with common clinical findings of an unclear retinal margin and an inflammatory membrane over the retina, as seen by fundus examination, may be helpful for early diagnosis and treatment.

Dieulafoy's disease, a vascular anomaly mainly in the upper stomach, is a rare but potentially life-threatening cause of upper gastrointestinal bleeding. Pathogenesis is still controversial, but the most accepted theory is that a persistent caliber vessel in the submucosa is exposed by a small mucosal erosion leading to massive bleeding. The bleeding site is usually within 6 cm of the esophagogastric junction in the cardia or fundus of the stomach. The treatment of choice is therapeutic endoscopy or surgery. The age of patients reported is mainly between 50 and 70 years, and patients of pediatric age are extremely rare. We are reporting a 5-year-old male patient who had Dieulafoy's disease which was diagnosed by emergency upper gastrointestinal endoscopy. Endoscopic finding was a nodular lesion with an adherent clot on the lessor curvature of the stomach 2 cm below the esophagogastric junction. Epinephrine and $Beriplast^{(R)}$ was injected in the lesion. On the second day after endoscopic sclerotherapy, the patient had recurred massive hematemesis and accompanying shock. So we performed gastrotomy and ligation. After the operation, he showed an improved general condition and was discharged at the 12th hospital day.

The regional distribution and relative frequencies of endocrine cells were studied immunohistochemically (PAP methods) in the alimentary tract and pancreas of the toad, Bufo bufo gargarizans Cantor using specific antisera against bovine Sp-1/chromogranin (BCG), serotonin, bombesin, gastrin, substance P (SP), somatostatin, insulin, glucagon, pancreatic polypeptide (PP), vasoactive intestinal polypeptide (VIP) and secretin. Nine kinds of endocrine cells were identified in this study. Spherical or spindleshaped immunoreactive (IR) cells were located in the gastric glands of stomach regions, in the basal portion of the epithelium of intestinal tract or esophagus, and in the exocrine or pancreatic islets with variable frequencies. In the alimentary tract, BCG-IR cells were found in the fundus and pylorus with rare and a few frequencies, respectively. Serotonin-IR cells were demonstrated in the whole alimentary tract including the esophagus. Bombesin- and SP-IR cells were restricted to the stomach regions and gastrin-IR cells were restricted to the pylorus. Somatostatin-IR cells were detected throughout the whole alimentary tract except for the large intestine, However, insulin-, glucagon-, PP-, VIP- and secretin-IR cells were not detected in the alimentary tract. In the pancreas of toad, the distribution and relative frequency of endocrine cells were similar to those of other mammals. Insulin-IR cells were located in the central portion of the pancreatic islets and interspaces of exocrine portions, and glucagon-, somatostatin- and PP-IR cells were detected in the marginal regions of the pancreatic islets and interspaces of exocrine. However, other IR cells were not found in the pancreas. In conclusion, the regional distribution and relative frequency of the endocrine cells in the alimentary tract and pancreas of the toad were similar to other anuran species but some differences which might be caused by feeding habits and species specification were also observed.

Bronchial artery embolization (BAE) is a well accepted and effective treatment for massive and recurrent hemoptysis. However, several complications of BAE have been reported. Cortical blindness is defined as a loss of vision caused by bilateral occipital lobe lesions with normal pupillary light reflexes and a normal fundus. The reported incidence of transient cortical blindness(TCB) after cerebrovertebral angiography is approximately 1%. Two cases of TCB after BAE were found from a Medline search. Here, we report another case of TCB who was treated with BAE for a massive hemoptysis.

Objectives : The purpose of this study was to analyze and report status of Korean Medicine Ophthalmology patients who did funduscopy examination. Through this, we hope that the development of our diagnosis and treatment. Methods : From June 1, 2010 to May 31, 2019, Based on the electronic medical records of patients who had funduscopy examination at Korean Medicine Ophthalmology, Busan University Korean Medicine Hospital, the gender, age, visiting motives and paths, diagnosis, examination number of years, other eye examinations and treatments method were summarized and analyzed. Results : 463 patients were able to check the electronic medical records. They were 283 females and 180 males. The mean age of the patients was 51.5 years and elderly patients who 50s and 60s were 49.3% of whole patients. The most common motives for Korean Medicine Ophthalmology visitation was 'combination treatment with other department in Korean Medicine Hospital'. Outer eye diseases were 283 cases, inner eye diseases were 198 cases. Dry eye syndrome, asthenopia, visual discomfort, conjunctivitis, and eye discomfort were most common in the outer eye diseases. Cataracts, Vitreous floater, Macular Degeneration, Glaucoma and Ocular Pain were most common in the inner eye disease. The most common parts of outer eye diseases were Conjunctival, lacrimal gland, paralytic, corneal, eyelid and front uveal, scleral disease and then in inner eye diseases parts, Retinal, lens, vitreous, glaucoma, optic nerve, behind uveal, choroid disease were most common. The number of funduscopy examination was ups and downs. Herbal medicine was the most common used. Conclusions : The funduscopy examination is essential for diagnosis and treatment of eye disease. We hope that the use of fundus examination and other ophthalmologic examination will be expanded soon in Korean Medicine Ophthalmology.
