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.

Sebaceous adenoma is a benign organoid tumor of proliferating, incornpletely differentiated sebaceous glands. We report a case of sebaceous adenoma in a 15-year-old male. He had a 1.7 x 2.2 cm sized, asymptomatic, srnooth, round, raised, firm, reddish tumor on the left quadrant of abdomen. Histopathologically, the tumor was composed of lobules of irregular size and shape, and sharply demarcated from the surrounding tissue, The most lobules showed undifferentiated germinative and mature sebaceous cells in about equal number. Sebaceous cells in lobules were stained for prekeratin by means of avidin-biotin-peroxidase complex method. Ten months after surgical excision there was no evidence of recurrence.

Since in 1963 Waters first described the techniques of guiede blind tracheal intubation to solve the problem of difficult in airway maintenance in patients who have deformity of the upper jaw, several methods are recommended to overcome a difficult intubation. We experienced successful retrograde endotracheal intubation without significant complications as follows. Using loca anethesia, 16G Tuohy needle was passed through the anterior wall of the trachea 1.5 to 2.0 cm below the cricoid cartilage in the midline. The needle was directd upward foward the larynx and the epidural catheter was insertedc through it and advanced retrograde between the vocal cords and into mouth or nose. The endotracheal tube was threaded over the catheter and the proximal end of the catheter was clamps by kelly forceps. By keeping the catheter taut and coincidently pulling back, the tube was adnvanced in to trachea.

We report an atypieal case of xanthoma without evidence of underlying disease, A 50-year-old asymptomatic, yellowish, flat plaques on the upper eyelids, trunk and thighs, and huge, deep-seated tumors on anterior aspect of the neck, back and ankle areas of 3 years duration. Biopsies were performed at the lesions of the neck and hack. Two biopsy specimens showed the same findings of xanthoma, respectively. The appearance of refrigerated serum was clear. Paper electrophoresis didn't show elevation of any lipoprotein, suggesting normolipoproteinemia.
