  • This study represented an endeavor to observe clinical signs and pathological lesions in broiler chicks suffering from experimental Infectious stunting syndrome(ISS). One hundred and twenty day old broiler chicks were divide randomly into two equal groups i.e. control (A) and inoculated (B). At day one of age each chick of the groups (A and B) was dosed with one ml of either tryptose phosphate broth or prepared inoculum respectively. Chicks of both the groups were housed separately under similar standard management. Inoculation induced characteristic clinical changes in birds of treatment group like of brownish diarrhea, lameness, feather developing problems and paleness of combs, wattles and shanks. By day-29 of the experiment all the stunted birds from group-B and an equal number of birds from group-A were slaughtered. These birds were examined thoroughly to record the gross changes in various structures and then the severely affected organs were processed for histopathological examination. The skeletons of affected birds were brittle, keel bones showed quite prominence while the muscles and subcutaneous tissues were almost devoid of fat. Grossly it was observed that pancreas, spleen and bursa of Fabricius were severely atrophied while the intestines were ballooned with undigested feed and gases. Histopathological examination of pancreas and spleen revealed a classical picture necessary for understanding the pathogenesis of the syndrome. The acivar cells of pancreas were atrophied and underwent vacuolation, degeneration and vecrosis. The zymogen granules were almost absent from the acinar cells. A characteristic change was an inflammatory reaction in one or more pancreatic ducts where the epithelium and fibrous tissues occluded the lumen of the ducts and led to the obstruction in pancreatic drainage.

  • Objectives : The Gyotae-hwan formula has traditionally been applied to conditions of fearful throbbing[怔忡] and insomnia due to disharmony of the Heart and Kidney, of which experimental and clinical research has been carried out while those on its pathological mechanism and constituent compatibility have been inadequate. Methods : Pathological mechanism and constituent compatibility of the Gyotae-hwan formula as listed in the 『Comprehensive Medicine According to Master Han』(韓氏醫通) and the『Simple Recipes for Four Disciplines』(四科簡效方) were analyzed. Findings from recent researches searched using the keywords '交泰丸' and '교태환' in the OASIS and CNKI databases were referenced as well. Results : The Gyo-tae hwan was first mentioned in the text 『Comprehensive Medicine According to Master Han』by Mao Han in terms of constituent medicinals and application while measurements and name of formula were not listed while the concept of harmony between the Heart and Kidney was mentioned. In the『Simple Recipes for Four Discipline s』 written by Shixiong Wang, measurements of constituent medicinals, usages and name of formula were finally mentioned, along with its efficacy to treat fearful throbbing and insomnia due to disharmony between the Heart and the Kidney. Conclusions : In conclusion, the Gyo-tae hwan uses Coptidis Rhizoma as chief herb and Cinnamomi Cortex as assistant herb to change the state of disharmony between the Heart and Kidney to a harmonious state, treating insomnia and fearful throbbing.

  • Rock wool, a kind of asbestos substitutes, was analyzed for its physicochemical properties. After fivers of rock wool were instilled into rat lungs, These pathological changes were evaluated. In addition, the fibers in the lungs were counted and characterized after the lungs were treated for electron microscopical analysis. The lungs of rats showed pathological lesions such as granulomatous changes, but these lesions disappeared at 28 days groups after instilled rats. The rock wool fibers in the lungs decreased more 50 % after 28 days instilled into rat lungs. And rock wool showed early change in fiber compositions after 3 days compare with chrysotile showed after 7 days instilled into rat lungs. This study showed that the durability of rock wool in the lungs is more milder than chrysotile.

  • One of the most striking features of modern society in the 21st century, is increased levels of aggression. Aggression refers to aggressive or hostile behavior, and is manifested in suicide or an attack against others. Aggression in modern society is more accidental, reckless, and aimless than before. As more patients visit hospitals due to the serious problem of aggression control, we need to address the nature of this growing aggression. The authors analyzed sources and the nature of aggression, based on the movie 'American Psycho.' The main character of the movie, Patrick, is similar to many people today, with traits such as egotistical thinking, lack of empathy, demand for attention and admiration, and exploited and superficial relationships. Patrick's aggression is in reaction to narcissistic injury. Through this, one can think of pathological narcissism, behind growing aggression in modern society. There are a number of social and environmental factors, attributable to increasing narcissism in modern society. Among them, change in parenting practices, and parent-child relationships, is likely to have affected increase in narcissism in terms of personality development. In conclusion, when treating patients exhibiting aggression in psychotherapy, it is critical to fully consider the possibility of pathological narcissism and its use in analysis.

  • 1. Objectives Creutzfelt Jacob Disease is one of a group of neurodegenerative disorders causing spongiform encephalopathies due to a infection of prion or unconventional slow virus on central nerve system. The diagnosis of this disease is not easy and there is currently no cure. This article is to report our case about a female patient who was not diagnosed as CJD at the early period so that we treated her with Yangkyuksanhwa-tang(凉膈散火湯) and Jihwangbaekho-tang(地黃白虎湯). 2. Methods Magnetic resonance imaging(brain MRI), blood test and computer tomography were performed. The treatment for this patient was clinically based on Sasang Constitutional Medicine. 3. Results and Conclusions (1) Visual field defect, ataxia, myoclonus, sweating and dysuria were the main symptoms of the patient. (2) The pathological change in parenchyme was not revealed during the early periods by MR imaging. So the diagnosing CJD was not possible during the time in this case. (3) Jihwangbaekho-tang(地黃白虎湯) improved her myoclonus and sweating. Bur her mental disorder and the progress of the pathological change in the parenchyme was not able to be treated.

  • Purpose: Abnormal potassium channels expression affects vessel function, including vascular tone and proliferation rate. Diverse potassium channels, including voltage-gated potassium (Kv) channels, are involved in pathological changes of pulmonary arterial hypertension (PAH). Since the role of the Kv1.7 channel in PAH has not been previously studied, we investigated whether Kv1.7 channel expression changes in the lung tissue of a monocrotaline (MCT)-induced PAH rat model and whether this change is influenced by the endothelin (ET)-1 and reactive oxygen species (ROS) pathways. Methods: Rats were separated into 2 groups: the control (C) group and the MCT (M) group (60 mg/kg MCT). A hemodynamic study was performed by catheterization into the external jugular vein to estimate the right ventricular pressure (RVP), and pathological changes in the lung tissue were investigated. Changes in protein and mRNA levels were confirmed by western blot and polymerase chain reaction analysis, respectively. Results: MCT caused increased RVP, medial wall thickening of the pulmonary arterioles, and increased expression level of ET-1, ET receptor A, and NADPH oxidase (NOX) 4 proteins. Decreased Kv1.7 channel expression was detected in the lung tissue. Inward-rectifier channel 6.1 expression in the lung tissue also increased. We confirmed that ET-1 increased NOX4 level and decreased glutathione peroxidase-1 level in pulmonary artery smooth muscle cells (PASMCs). ET-1 increased ROS level in PASMCs. Conclusion: Decreased Kv1.7 channel expression might be caused by the ET-1 and ROS pathways and contributes to MCT-induced PAH.

  • This study was undertaken to find out the effect of dropwort on histopathological changes of cadmium toxicity in mice. Thirty two mice of BALB/c strain were divided into a control group (A) and three experimental groups (B, C, D). Each group was consisted of four males and four females : group A received tap water and basal diet, group B received tap water and diet supplemented with 100 mg/kg of cadmium, group C received dropwort juice and diet supplemented with 100 mg/kg of cadmium, group D received dropwort juice and basal diet. All mice were dissected on the 35th day. Pathological changes in liver, kidney, spleen, heart, lung, stomach and muscle were observed. Group D showed no significant change as the control group. But group B showed many cytoplasmic vacuoles and necrosis of hepatocytes, glomerular swelling, and degeneration and necrosis of convoluted tubules in kidney, marked congestion and hemorrhage, and a large number of variably sized alveolar macrophages appearance in lung and swelling in some part of muscle fiber. On the other hand, group C showed a little convalescent changes and maintained their normal architectures in liver, kidney, lung and muscle.

  • In this paper the acoustic characteristics of pathological voice, which are measured before and after surgical operation, are compared. This experiment is conducted for the purpose of predicting patients' speech after operation. The voices are recorded from the same patients. Jitter, shimmer and other parameters are. computed and their statistical characteristics are compared. Also spectral changes, such as formant frequency shift and spectral slope change, are compared. From the experimental results, it is verified that not only source characteristics but also vocal tract components vary. And this indicates that the modification of source parameters are not enough for the prediction. Also the result indicates that the operation causes change to both the physical shape of vocal folds and the manner of articulation.
