This study was undertaken to observe the effects of centrally administred antihistamines on the blood pressure. Diphenhydramine(DPH), a H1-receptor antagonist, and ranitidine(RAN), a H2-receptor antagonist were administered intracerebroventricularly(icv) on urethane-anesthetized rabbits. 1) Both DPH and RAN administered intraccebroventricularly increased blood pressure, however the intravenous(iv) adminstration of them did not affect blood pressure. The pressor response to icv DPH was dose-dependent, but that to icv RAN was not. 2) The pressor response to icv DPH(1mg) was either markedly attenuated or reversed to depressor response by the pretreatment with icv phentolamine(250,500ug), and iv chlorisondamine(0.1, 1mg/Kg) and iv phenoxybenzamine(1mg/Kg). In cord-sectioned rabbtis, icv RAN) 1mg) did not produce pressor response. 3) The pressor responsr to icv RAN(1mg) was not affected by the pretreatment with icv phentolamine(500ug), iv chlorisondamin(1mg/Kg) and iv phenoxybenzamine(1mg/Kg), and iv phenoxybenzamine(1mg/Kg). RAN also producted pressor response in cordsectioned rabbits. These results suggest that the pressor response to icv DPH is elecited by increasing peripheral sympathetic tone via the stimulation of central alpha-adrenoreceptors and the pressor response to icv RAN is produced by releasing some humoral facotr which can increase blood pressure.

Encephalocele is a relatively rare congenital anomaly which is classified into occipital, parietal, anterior syncipital and anterior basal type regarding to the protrusion site through the bony defect of the skull. Anterior basal type of encephalocele is important in view of it's pathogenesis as well as diagnostic difficulty because of invisibility on external appearance. We have experienced a case which could be best fit to anterior basal encephalocele. This type of encephalocele is extremely rare. This report deals with a case of deadborn of 34 weeks of gestation with body weight of 2400gm and head circumference of 32 cm. There was no evidence of protrusion of brain on external examination. On autopsy the normal brain structure was compressed by abnormal mass of brain with normal consistency which was found in the petrous portion of the parietal area and covered partly by the dura. In this case, there were another associated anomalies, such as atrophy of the left optic nerve, hemihypoplasia of the left mandible, patent ductus arteriosus, bilateral hydrocele, and Meckel's diverticulum.

PURPOSE: We studied results of the communited distal radius fracture treated with allogenic cancellous bone graft and volar locking plate in the elderly. MATERIALS AND METHODS: We studied 29 cases of communited distal radius fracture treated with allogenic cancellous bone graft and volar locking plate from April 2009 to April 2013. Fracture was classified according to AO/OTA classification. Postoperative clinical evaluation was performed with measurement of wrist range of motion (ROM) at last follow-up, modified Mayo wrist scoring system (MMWS), and visual analogue pain scale (VAS). Radiologic evaluation was performed with measurement of radial length on immediate postoperation and last follow-up, radial inclination, volar tilt and ulnar variance checked at the last follow-up using Sarmiento criteria. RESULTS: Using the MMWS, 13 cases were classified as 'good', 10 'fair', and 5 'normal'. The average wrist ROM was 88.5% for flexion, 92.2% for extension, 90.5% for adduction, and 94.0% for abduction. The average VAS was 1.7. On the last follow-up, average radius length, radial inclination and volar tilt did not show statistically significant improvement (p>0.05) compared to immediate post operation measurements, and according to Sarmiento criteria, 5 cases were classified as 'good', 14 'fair', and 7 'normal'. CONCLUSION: Treatment of severe communited distal radius fracture accompanied by bone defect with volar locking plate and allogenic cancellous bone graft is a satisfying and effective treatment method in the elderly.

The fatty hamartoma of pericardium is characterized by abnormal accumulations of adipose tissue forming a recognizable mass. We reported a case that could best be put into "fatty hamartoma" group. This 66 year old male presented with atrial fibrillation came in for a anterior mediastinal mass. He received an operation for adenocarcinoma of ascending colon several months ago. The chest CT revealed an inhomogeneous mass in the right anterior mediastinal area, which was not clearly demarcated from the right cardiac border. The heart was deviated to the left side due to the mass. Surgical excision was performed under the impression of cardiac teratoma. The large mass was well encapsulated, and was bright yellow and partly pink, and measured 12x8 cm. Microscopically, the mass consisted predominantly of mature fat cells and abundant fibrous tissue with scattered nests of primitive cardiac muscle cells. Reviewing the literature we found the term "fatty hamartoma" could also refer to rhabdomyolipoma or fibrolipoma. Since it contains entrapped cardiac muscle cells, abundant fibrous tissue, multiple blood vessels and fetal fat cells, it could best the categorized into "hamartoma". The term "fatty" represents it's main component. Therefore we propose the term "fatty hamartoma" that could to be used further.

BACKGROUND: Our aim was to make a comparative analysis of radiological and clinical outcomes of using either one or two interlocking distal screws on a Polarus intramedullary nail for the internal fixation of humeral shaft fractures. METHODS: From January 2008 to March 2014, we enrolled 26 patients with humeral shaft fractures who were operated on using intramedullary nails. The patients were divided into 2 groups according to how many interlocking distal screws were used to lock the Polarus nail: in group 1, a single interlocking distal screw was used in 12 patients; and in group 2, double interlocking distal screws, in 14 patients. We compared the degree of recovery of the displaced fracture fragments between the two groups. To compare the nonunion and shoulder function, we assessed each patient's modified American Shoulder and Elbow Surgerns (ASES) score. RESULTS: We found that 10 of 12 fractures achieved union in group 1, and 13 of 14 fractures, in group 2. We did not find a meaningful difference in the time to bone union between the two groups. The percentage of recovery of displaced fracture fragments until union was 66.9% for group 1 and 59.41% for group 2. At the final follow-up, we found that the scores for shoulder joint modified ASES was 78.7 for group 1 and 80.7 for group 2. CONCLUSIONS: Our results show that if locked appropriately, even a single screw on a Polarus nail can provide satisfactory radiological union and improved clinical outcome after intramedullary nailing of humeral shaft fractures.

OBJECTIVE: The presence of the various cytokines in human peritoneal fluid has been evaluated incompletely. Changes in cytokine lefels may be related to activation of peritoneal macrophage and T-lymphocyte, development of endometriosis, and infertility. This study assesses peritoneal fluid levels of interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10) and tumor necrosis factor-alpha (TNF-alpha) in infertile women with endometriosis and normal women without endometriosis. Design : Prospective and case-control study in university hospital. MATERIALS AND METHODS: Cytokine levels in peritoneal fluid obtained during laparotomy or laparoscopy from 21 patients in infertile patients in infertile patients with endometriosis and 24 controls undergoing laparotomy or laparoscopy with no evidence of pelvic endometriosis were determined by enzymelinked immunosorbent assay. RESULTS: The mean levels of interleukin-6 in infertile patients with endometriosis and controls were 72.7+/-23.7 pg/ml and 18.5+/-9.7 pg/ml respectively (p=0.02). Similarly, the mean levels of interleukin-8 in infertile patients with endometriosis was significantly higher than that of controls (445.0+/-89.6, vs 45.1+/-48.4, p=0.04). The mean concentration of interleukin-10 in infertile patients with endometriosis was significantly lower than that of controls (1.09+/-0.04 vs 2.19+/-0.03, p=0.03). The level of tumor necrosis factor-alpha was not significantly different between the two study groups. CONCLUSIONS: Increased IL-6 and IL-8 and decreased IL-10 levels in the peritoneal fluid may be related to pathogenesis in the endometriosis and infertility, suggesting that partially contribute to the disturbed immune regulation observed in infertili women with endometriosis.
