This study was performed to evaluate the effect of topical and intravenous heparin on thrombosis and patency in the microvascular anastomosis of the traumatized veins. Nine white rabbits weighing about 2kg were used. After exposure of both femoral veins, the veins were crushed by the jaws of smooth needle holder in order to create a thrombosis model. Transectional incision was made in the vein. The animals were then divided into 3 groups based on the administration method of heparin: 1) Experimental Group I, topical irrigation of lumen with heparin saline solution (n=6); 2) Experimental Group 2, topical irrigation of lumen with heparin saline solution and intravenous injection of heparin (0.75 mg/kg) via the marginal ear vein for 3 days; 3) Control Group, topical irrigation of lumen with saline solution (n=6). The patency was evaluated with empty-and-refill test and thrombus formation was judged by surgical microscope. The results were as follows: 1. Thirty minutes after microvascular anastomosis, the patency fall Experimental Groups was better than Control group. However, there was no significant difference among groups. 2. Three days after anastomosis, the patency of all Experimental Groups was much more improved than that of Control Group (P<0.05). There was no significant difference between Experimental Group 1 and 2. 3. Three days after anastomosis, the amount of thrombus in all Experimental Groups was much less than that of Control Group (P<0.05). 4. In histologic findings a lot of luminal thrombus were observed around sutured area in Control Groups. Few luminal thrombus was observed in all Experimental Groups. Mild necrosis in the vessel wall was observed around sutured area in all specimens. These results indicate that topical irrigation of heparin may improve the patency and inhibit the formation thrombus in the microvascular anastomosis of the traumatized veins.

An echogenic lobulated round mass in the head of pancreas was found during abdominal ultrasonography for routine checkup on a 34 year-old man. CT and MRI showed characteristic findings of lipoma. Clinical followup confirmed intrapnacreatic lipoma, which had been reported only once proviously. This lesion should be added to the list of benign connective tissue tumor of the pancreas.

BACKGROUND: Epidural steroids injections are often used for the treatment of low back pain but their effects on the endocrine system have not been determined. Few studies have quantified the degree or duration of the suppression of the hypothalamic-pituitary-adrenal (HPA) axis in humans given epidural triamcinolone injection (ETI) for low back pain. The evaluation of the blood adrenocorticotropic hormone (ACTH) and cortisol was undertaken to determine the extent of suppression of the HPA axis in patients given ETI. METHODS: Lumbar epidural triamcinolone injections were performed on the painful lumbar intervertebral space with patients in the lateral decubitus position. The injection consisted of 40 mg of triamcinolone acetonide diluted in 10 mL of 1% lidocaine. Patients remained in the lateral position for 10 min after the procedure. Basal blood sampling was performed at 30 min before ETI and tested blood sampling was obtained at 7 days, 10 days, and 14 days after ETI. RESULTS: The blood cortisol level was significantly decreased at 7 days and 10 days but at 14 days was not significantly decreased and the blood ACTH level was not significantly decreased at 7 days, 10 days, and 14 days. CONCLUSIONS: Above results demonstrate that blood ACTH and cortisol level normalize 7 days and 14 days, respectively, after epidural triamcinolone 40 mg injection.

PURPOSE: In colon cancer, the most frequent genetic alteration is found in p53 tumor suppressor gene residing on the short arm of chromosome 17. In order to investigate the significance of wild-type p53, we transfected wild type p53 into human colon cancer cell lines and analysed tbeir biologic effects. MATERIALS AND METHODS: For analysis of p53 status in cell lines, polymerase chain reaction-single stranded confonnation polymorphism (PCR-SSCP), PCR-direct sequencing and Western blot analysis were employed. Transient transfection with liposome-p53 complex was followed by cell biologic assay. RESULTS: We found that twelve of fifteen human colon cancer cell lines showed mutation of p53 by PCR-SSCP method. These results almost corresponded to p53 protein accumulations assessed by Westem blot using PAbl801. After transfection with lipafect- AMINE and wild type p53 complex on p53 mutant type cell line (LS1034), viability was reduced to 17.9%, and invasiveness was reduced to 37.3%. Morphologically, wild type p53 transfected cells showed lumen formation and apoptosis after induction of differentiation by Matrigel. CONCLUSION: Wild type p53 transfection into p53 mutated colon cancer ceil line resulted in restoration of tumor suppressor effect of p53, and this model would be one of the experimental systems for p53-based gene therapy.

Phakomatosis pigmentovascularis is a rare cutaneous malformation characterized by a combination of nevus flammeus and pigmentary nevus such as nevus of Ota, nevus of Ito, mongolian spots, nevus spilus. It is often associated with systemic organ involvement. We report two cases of phakomatosis pigmentovascularis. The first was a 11-year-old boy, who had had diffuse nevus flammeus, mongolian spots since birth, and congenital glaucoma. The second case was a 9-year-old boy who had had nevus flammeus, mongolian spots, nevus of Ota, and nevus of Ito over various parts of his body since birth. He also had leg-length discrepancy, avascular necrosis of the femur head, congenital temporal alopecia and varicose veins.

Rhino-orbito-cerebral muconnycosis is an uncommon fatal fringal infection, almost exclusively seen in diabetic or other itnmunocompromised patients. Recurrent transient ischemic attacks(TIAs) as initial presenting sign of rhino-orbito-cerebral mycormycosis has not been reported to our knowledge. We report a patient with muconnycosis unusually presenting with recurrent TIAs, followed by central retinal artery occlusion, multiple cranial nerve palsies, and then cerebral infarction in the territory of middle cerebral artery.

BACKGROUND: Of the many prognostic factors for breast cancer, the relationship between an infiltration of inflammatory cells and the prognosis is debatable. Of the chemokines affecting cancer's inflammatory reactions, chemokine (C-X-C motif) ligand 16 (CXCL16) has attracted attention for its prognostic value in many cancers, including colorectal cancer and renal cell carcinoma. But the situation for breast carcinoma is unknown. The aim of this study was to examine the relationship between the prognostic factors and the CXCL16 expression in patients with breast carcinoma. METHODS: The patients (n=106) diagnosed with invasive ductal cancer of the breast were enrolled. We reviewed the clinicopathological factors of these patients, hematoxylin and eosin stains were prepared and estrogen receptor (ER), human epidermal growth factor receptor 2 (HER2/neu) and CXCL16 immunostaining was performed. RESULTS: The ER expression was significantly correlated with age and inflammation. A CXCL16 expression was noted in 81.1% of the cases. No association was evident between a CXCL16 expression and any other parameter, including the survival rate. Multivariate analysis did not implicate ER, HER2/neu or CXCL16 as an independent prognostic factor, but the tumor size was independent predictive factor for the patient outcome. CONCLUSIONS: An inflammatory reaction mediated by CXCL16 is not associated with the prognosis of breast cancer or any clinicopathological factors.
