An experiment was conducted to investigate the relationship between blood hormone levels and light cycle on performance of Korean native chicken. One hundred and two Korean native chickens were grouped into three treatments of natural light cycle (Control), 13L:11D (T2), and 16L:8D (T3). The egg production, egg weight, feed intake, serum melatonin and estrogen level were periodically measured from 22 to 34 weeks, respectively. The laying rates of T2 and T3 were significantly higher than that of the Control (P

Objective : The purpose of this study was to determine the optimal volume of injected cement and its distribution when used to treat vertebral compression fractures, and to identify factors related to subsequent vertebral fractures. Methods : A retrospective analysis of newly developing vertebral fractures after percutaneous vertebroplasty was done. The inclusion criteria were that the fracture was a single first onset fracture with exclusion of pathologic fractures. Forty-three patients were included in the study with a minimum follow up period of six months. Patients were dichotomized for the analysis by volume of cement, initial vertebral height loss, bone marrow density, and endplate-to-endplate cement augmentation. Results : None of the four study variables was found to be significantly associated with the occurrence of a subsequent vertebral compression fracture. In particular, and injected cement volume of more or less that 3.5 cc was not associated with occurrence (p = 0.2523). No relation was observed between initial vertebral height loss and bone marrow density (p = 0.1652, 0.2064). Furthermore, endplate-to-endplate cement augmentation was also not found to be significantly associated with a subsequent fracture (p = 0.2860) by Fisher's exact test. Conclusion : Neither volume of cement, initial vertebral height loss, bone marrow density, or endplate-to-endplate cement augmentation was found to be significantly related to the occurrence of a subsequent vertebral compression fracture. Our findings suggest that as much cement as possible without causing leakage should be used.

A case of Behcet's syndrome found in a 22 years old male was is reported along with the histological and immunohistochemical studiesfindings. He The patient had had received prolonged medical therapy of anti-inflammatory agents for the conjunctival ulcer, genital ulcer, oral ulcer, and intestinal ulcers since the first onset of the Behcet's syndrome about approximately 7 years agoearlier. Recently, he felt the athickening of both corners of his lip causing that caused mouth opening difficultydifficulties. A plastic rReconstructive surgery was performed to enlarge the size of the oral orifice by multiple Z-plasty incisions, and finallywhich resulted in proper enlargement of the circumferential length of the lip. During the operation, a scar-like thick fibrous tissue was obtained and examined pathologically. In theThe microscopic observation the revealed the submucosal lesion was to be diffusely fibrosed with the a distribution of sclerotic collagen bundles. Particularly, sSeveral foci of collagen degeneration were found observed in the deep connective tissue, and the degenerating collagen bundles were gradually lost their fibrillar appearance. In the immunohistochemical observations, the foci of collagen degeneration was were strongly positive for IgK, but almost negative for TNF${\alpha}$ lysozyme, and MMP-3. Taken together, it was presumed that tThe submucosal fibrosis was presumed to have firstly presented in this study was probablybeeninduced by the prolonged anti-inflammatory therapy, which may inhibit the removal of sclerosed collagen bundles by the cell-mediated immunity and proteolytic digestion of macrophages, and that it was secondarily aggravated by the deposition of immunoglobulins derived from an autoimmune origin. Therefore, even after the successful plastic surgery of the lip to ameliorate the mouth opening difficulty, the recurrent submucosal fibrosis of lip should be carefully managed in the follow-up treatment.

Objectives : The purpose of this study was to develop the Korean standard pattern identifications for stroke-III (KSPIS-III). KSPIS-III includes 4 major pattern identifications (PIs) and clinical indicators for each. Methods : To extract the indicators for 4 major PIs, we analyzed 1548 clinical data from 15 traditional Korean medicine hospitals. Patients got acute stroke within 30 days from onset. Two physicians independently checked 65 indicators and performed pattern diagnosis. If the PI were diagnosed the same, PI would be confirmed. First we built an assumption model that set up the relationship among pattern identifications. Second, we extracted the indicators for fire-heat pattern and qi deficiency pattern by comparison between excessive and deficiency group, heat and non-heat group. By comparing yin deficiency pattern and 3 other patterns respectively, we extracted the indicators for yin deficiency pattern. Dampness-phlegm pattern indicators were extracted by the same method. Results : After cross tabulation with 65 indicators on the basis of our assumption model, we finally extracted 19 indicators for fire-heat pattern, 11 for qi deficiency pattern, 7 for yin deficiency pattern, and 7 for dampness-phlegm pattern. Conclusions : KSPIS-III was more improved than KSPIS-II because it was based on more clinical data. Further study to establish the PI diagnostic model would be required for practical use in the clinical field.

Background and Purpose The purpose of this study was to confirm that what symptoms are adequated indicator in the Gi-Deficiency patients. Methods In the time period July. 2005 to Sep. 2006, 136 patients with a first-ever stroke admitted in the department of Internal Medicine of Daejeon University Oriental Medical Hospital in Daejeon city, Wonkwang Oriental Medical Hospital in Iksan, JeonJu city were included. Patients were hospitalized within 3 months after the onset of stroke. Stroke patients had been interviewed by resident who studied standard operation procedures in Fundamental Study for Standardization and Objectification of Differentiation and Pattern Identification of Syndrome of Oriental Medicine for Stroke. Gi-deficiency patients was confirmed by medical specialist diagnosis, resident diagnosis, case report form analysis without a dissenting voice. Results Gi deficiency group included 23 case, Non Gi deficiency group 47 case out of 136 patients. Fatigue, weakness purse, somnolence, low voice, difficulty of uprise, pale face, pale tongue were higher among Gi deficiency group. Gi deficiency and Non Gi deficiency patients do not significantly differ in white coating tongue, light-red tongue, poor appetite, frequent sweating, teeth printed tongue. Conclusions This study was insufficiency because sample size very small. More data from prospective cohort studies will help to Korean Standard Differentiation of the Symptoms and Signs for the stroke.

Pyomysitis is a primary acute bacterial infection of large skeletal muscule, usually occuring in the absence of specific cause of infection. Pyomyositis has been reported mainly in tropical countries and was rare in temperate climates. but it has been recognized with increasing frequency. Toxic shock syndrome(TSS) is an acute mutisystemic disease characterized by high fever, hypotension, multisystem dysfunction and erythematous rash followed by skin desquamation 8-12 days after onset. Especially, TSS and pyomyositis are rare conditions in the pediatric population. We experienced one case in a healthy 13-year-girl who developed pyomyositis of the right ileac and gluteal muscles associated with TSS caused by methicillin resistant Staphylococcus aureus. We reports a case of acute pyomyositis with TSS, in which the diagnosis was difficult because of the relative rare incidence in temperate climates and its vague symptoms. To our knowledge, this is the first reported case of pyomyositis with TSS in Korean pediatric population.

This study was investigated to test whether paternal DNA that was destined for degradation was properly licensed by testing for the presence of mini-chromosome maintenance protein (MCM) 7 and origin recognition complex (ORC) 2 in the paternal pronuclei. ORC2 is one of the first licensing protein to come on and MCM7 is one of the last licensing protein to come on. Zygotes were prepared by injection of control and treated sperm injection (ICSI). To control for DNA breakage, epididymal spermatozoa were treated with DNase I to fragment the DNA, then injected into oocytes. The presence of MCM7 and ORC2 in the pronuclei of mouse zygotes was tested by immunohistochemistry, just before the onset of DNA synthesis, at 5 h after fertilization, and after DNA synthesis began, at 9 h post fertilization. We found that in all cases, both MCM7 and ORC2 were present in both pronuclei at 5 h after sperm injection, just before DNA synthesis began. This indicates that no matter how extensive the DNA damage, recruitment of licensing proteins to the origins of replication was not inhibited. Sperm DNA fragmentation does not prevent licensing of DNA replication origins. Furthermore, the embryo recognizes DNA that is damaged by nucleases. Our data indicate that the one-cell embryo does harbor a mechanism to prevent the replication of severely damaged DNA from spermatozoa, even though the embryos do not undergo classical apoptosis.

Extrahepatic portosystemic shunts, known as Abernethy malformations, were first reported by John Abernethy in 1793. They are classified into two types: Type I refers to a congenital absence of the portal vein and Type II refers to a shunt involving a side-to-side anastomosis with reduced portal blood flow into the liver parenchyma. This malformation is so rare that less than 100 cases have been reported in the medical literature. We report the case of a 13-month-old boy who had a congenital extrahepatic portocaval shunt with a hypoplastic portal vein. This case was complicated with an atrial septal defect and a large hyperplastic nodule in the liver. The patient was diagnosed with a Type II Abernethy malformation. We planned on surgical occlusion of the extrahepatic portocaval shunt. However, six months later, the patient had a sudden onset of a fever of unknown origin and developed hepatic encephalopathy. Although he underwent a liver transplantation, he died of acute hepatic failure.

Brain cells produce cytokines and chemokines during the inflammatory process of many neuronal diseases both in animal models and in patients. Inflammatory cytokines are the main responsible for the onset of inflammatory cascade. During the past decade, a growing corpus of evidence has indicated an important role of these cytokines in the development of brain damage. ZhenganXifeng-tang (ZGXFT) is a Korean herbal prescription, which has been successfully applied for the treatment of various neuronal diseases. However, its effect in experimental models remains unknown. Astrocytes are predominant neuroglial cells of the central nervous system and are actively involved in cytokine-mediated events in inflammatory disease. An inflammatory response associated with β-amyloid (Aβ) and interleukin (IL)-1β is responsible for the pathology of inflammation disease. To investigate the biological effect of ZGXFT, the author examined cytotoxicity, effect of cytokines (IL-6 and IL-8) secretion and expression of cyclooxygenase-2 (COX-2) on human astrocytoma cell line U373MG stimulated with IL-1β plus M fragment 25-35 (Aβ [25-35]). ZGXFT by itself had no effect on cell viability on human astrocytoma cells. The secretion of IL-6 and IL-8 was inhibited by pre-treatment with ZGXFT in human astrocytoma cells. In addition, the expression of COX-2 was induced by IL-1β plus AB[25-35] and was partially inhibited by treatment with ZGXFT. The author demonstrates the regulatory effects of inflammatory reactions by ZGXFT in human astrocytes for the first time and suggest the anti-inflammatory effect of ZGXFT may reduce and delay pathologic events of inflammatory disease.

The present study was investigated on type 2 diabetics' actual status of anti-diabetic functional food intake by patients who came to oriental medicine clinics in Daejeon. The male was 37.3% and female was 62.7% of the subjects. The onset of the disease was most common in the age of 50's. Also 40% of the subjects have been suffering for more than 5 years. 35.7% of men, 53.2% for women had family history. Also 61.5% of the patients chose to carry out both diabetic therapy and exercise at the same time. 69.3% of the subjects have had experiences in anti-diabetic functional foods. Anti-diabetic functional foods used to surveyed people were bean, ginseng, and ginseng steamed red of which efficacies were already well known. Besides these foods, other foods such as loach, crucian carp were also used as anti-diabetic foods, but their benefits as anti-diabetic functional foods are not yet fully investigated. Subjects first knew about the therapy because friends or relatives recommended to them and most of them have used for 6 months to 1 year. However, 78.9% of subjects answered 'not so effective' in a question about satisfaction of anti-diabetic functional food. Although many of the patients have tried taking functional foods, they only use them for short period of time and they don't show prominent effect. Therefore these results suggest that in order to use scientifically studied functional foods, education about anti-diabetic functional foods should taken.
