  • On MRI, abnormal signals of the intervertebral disc, destruction of the upper and lower vertebral body endplate around the disc, and bone marrow edema around the endplate are considered typical findings of infectious spondylitis. These findings can also appear in various non-infectious spinal diseases, such as degenerative changes, acute Schmorl's node, spondyloarthropathy, synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO), chronic recurrent multifocal osteomyelitis, and calcium pyrophosphate dihydrate crystal deposition disease. The imaging findings of infectious spondylitis that can be differentiated from these non-infectious spinal diseases on MRI are high signal intensity and abscess of the disc space, an abscess in the paraspinal soft tissue, and the loss of the linear low signal intensity on T1-weighted images of the bony endplate. However, these differentiation points do not always apply since there are many similarities in the imaging findings of infectious and non-infectious diseases. Therefore, for an accurate diagnosis, it is important to know the imaging characteristics related to the pathophysiology of not only infectious spondylitis but also non-infectious spinal diseases, which requires differentiation from infection.

  • A large proportion of patients with schizophrenia show a poor response to first-line antipsychotic drugs, which is termed treatment-resistant schizophrenia. Previous studies found that a different neurobiology might underlie treatment-resistant schizophrenia, which necessitates the development of different therapeutic approaches for treating treatment-resistant schizophrenia. This study reviewed previous studies on the pathophysiology of treatment-resistant schizophrenia and the pharmacological intervention, and forthcoming investigations of treatment-resistant schizophrenia are suggested.

  • Abnormal writing can result from a large variety of neurologic disorders of motor control. Primary writing tremor(PWT) in its pure form denotes occurrence of a disabling tremor induced by writing alone. Therefore PWT is typical task-specific tremor. PWT could be classified as either type A or type B. In a strict sense, type B PWT is not pure form of PWT because it is not task specific. We describe a case of PWT type A. A 53-year-old right handed policeman complained of a 4 year history of shaking of his right hand that interfered with writing. Tremor appeared during writing but not on adopting the hand position normally used for writing.

  • This study was designed to investigate the hyperlipidemia-healing effect of aqueous extract from Mahwangimun-tang(麻黃二門湯) and it was performed on the hyperlipidemia of rats induced by high cholesterol diet and Triton WR-1339. We prepared two types of hyperlipidemia model in rats induced by high cholesterol diet and Triton WR-1339. The amount of total cholesterol, HDL-cholesterol, LDL -cholesterol, triglyceride, phospholipid, free fatty acid, the activity of superoxide dismutase and glutathione were measured. The aqueous extract from Mahwangimun-tang showed significant decreasing effects on total cholesterol, LDL- cholesterol, triglyceride in the both model. And it showed significant increasing effects on HDL-cholesterol, the activity of SOD in both model. These results suggest that aqueous extract from Mahwangimun-tang has healing efficacy on hyperlipidemia induced by high cholesterol diet and Triton WR-1339.

  • This experimental study was designed to investigate the inhibitory effects of Sojihwangamibang on hyperlipidemia in rats induced by high cholesterol diet diet. Sprague- Dawley rats were divided into normal group, control group, SJB treated group. Obese rats were induced by high cholesterol diet treatment for 6 weeks including a oral administration of SJB for 4 weeks. In SJB group, serum total cholesterol, LDL cholesterol, triglyceride and glucose were significantly decreased, and HDL cholesterol was significantly increased compared with untreated control group. In SJB group, HMG-CoA and ACAT concentration of hepatic homogenate were significantly decreased compared with untreated control group. These results provide experimental evidence that SJB, applied currently in the clinical practice, appears to be effective for down-regulating risk factors of hyperlipidemia, and thus may be used as an objective information for the development of therapeutic agents.

  • Purpose: The purpose of this study was to identify knowledge and the Need of pathophysiology, perceived connectivity between knowledge of pathophysiology and clinical practice, and confidence and satisfaction with clinical performance by applying the knowledge to clinical practice, and to analyze the correlation between the knowledge, perceived connectivity, and confidence and satisfaction of clinical nurses. Methods: Subjects consisted of 149 clinical nurses who work at 7 general hospitals and 6 university hospitals located in Seoul, Incheon, and Gyeonggi province in Korea. Those who learned pathophysiology during their undergraduate program were recruited by using a convenient sampling. The data were collected between April 23 and May 24 in 2012. Participants responded to self-administered questionnaires about knowledge and the need of pathophysiology, and the perceived connectivity between knowledge and clinical practice, and confidence and satisfaction with clinical performance by applying knowledge to clinical practice. Results: Mean scores of knowledge and the need of pathophysiology were $2.88{\pm}0.34$ and $2.33{\pm}0.39$ each. Scores of knowledge and the need of 3 units such as fluid and electrolyte imbalance, acid-base imbalance, and alterations in the respiratory system were high among 23 units while that of adolescent disorders was the lowest. The mean score of perceived connectivity between knowledge and clinical practice was $7.32{\pm}1.57$, and those of confidence and satisfaction with clinical performance by applying the knowledge to clinical practice were $7.66{\pm}1.66$ and $7.42{\pm}1.67$ respectively. Knowledge of pathophysiology was positively correlated with the perceived connectivity between knowledge and clinical practice, and confidence, and satisfaction with clinical performance. Conclusion: The results indicate that knowledge and the need of pathophysiology in clinical nurses is above average, and that knowledge of pathophysiology is important in promoting perceived connectivity with clinical practice and increasing confidence and satisfaction with clinical performance by applying knowledge to clinical practice.

  • Purpose: The purpose of this study was to review the curriculum on biological nursing: structure and function of the human body, clinical microbiology, pathophysiology, and function and effect of drugs. Methods: Data was collected by searching and reviewing internet websites of 102 nursing schools or universities which provide 4 years nursing education in the Republic of Korea. The 74 curriculum on biological nursing science were available and analyzed by title, credits, hours, types of major (core or selective), offering semester, and laboratory practice. Results: The titles of 4 courses were diverse and were offered as core major (core requisites) or selective major. Structure and function of human body was offered in priority with more credits. Laboratory practice was poorly established in most courses. Biological nursing science courses were mostly taught in the second semester of the first year and the first or second semester of second year nursing education courses. Conclusion: There is a need to standardize the curriculum on biological nursing science and to expand the use of titles proposed by academic society. Also further research is necessary to identify curriculum details and to reflect the needs of professors.

  • Objective: Various psychological factors influence the occurrence of tension-type headaches. The aim of this study is to compare the level of alexithymia between tension-type headache patients and normal controls. Methods: Sixty-six subjects with tension-type headaches and 59 controls were studied. The Beck Depression Inventory and Toronto Alexithymia Scale (TAS-20K) were administered to the tension-type headache group and TAS-20K to the normal control group. Results: Compared with normal controls, the tension-type headache group had significantly higher alexithymia scores. There was also significant association between the level of alexithymia and the severity of the depression in tension-type headache patients. Conclusions: These findings suggest that patients with tension-type headaches have difficulty in expressing their emotions. And in patients with tension-type headaches, the more alexithymic they are, the more depressive.
