The aim of this study was to investigate the effect of electrical stimulation on healing of impaired wound and alteration of mast cells in experimental diabetic rats. Thirty male Sprague-Dawley rats were divided into three groups : incision (control), diabetes+incision (diabetes) and diabetes + incision + electrical stimulation (D/ES). Diabetes was induced in rats by streptozotocin (STZ) injection (60 mg/kg, one time) and 20 mm length incision wounds were created on the back after shaving hair. The electrical stimulation rats were treated with a current intensity of 30~50 V at 120 pps and $140{\mu}s$ for 10 days from 3 days after STZ injection. The lesion and adjacent skin tissues were fixed with 10% buffered formalin, embedded with paraffin. For wound healing analysis, hematoxylin-eosin (HE) and picrosirius red staining were performed. Mast cells (MC) were stained with toluidine blue (pH 0.5) and quantified at ${\times}200$ using a light microscope. The density of keratinocyte proliferation and microvessels in skin tissues were analyzed using a computerized image analysis system on sections immunostained with proliferative cell nuclear antigen (PCNA) and ${\alpha}$-smooth muscle actin (${\alpha}$-SMA), respectively. The results showed that the wound healing rate, collagen density and neoepidermis thickness, density of PCNA-positive cells and density of ${\alpha}$-SMA-positive vessels were significantly higher in D/ES rats than in diabetic rats. The density of MCs and degranulated MCs in D/ES rats were also significantly higher than those in diabetic rats. These findings suggest that the electrical stimulation may promote the tissue repair process by accelerating collagen production, keratinocyte proliferation and angiogenesis in the diabetic rats, and MCs are required for wound healing of skin in rats.

Purpose: Fracture of the frontal sinus accounts for 5-15% of all facial fractures. Only anterior table fracture occupies one third of the frontal sinus fracture. Conventional coronal approach is the standard treatment, but this method is very aggressive, especially in patient with simple, depressed, anterior frontal sinus wall fracture. We introduce new, simple technique for these patients, using small incision and Dual-top screws. Methods: A 27-year-old male patient was introduced to our department under the impression of fracture of frontal sinus, involving only anterior table. Under general anesthesia, 1.5 cm-sized, small incision was made on the suprabrow area. We reduced fractured fragment with two dual-top screws and 25G wires. Fixation was not necessary Results: The operation took about forty minutes, and the patient discharged 2 days after the operation. Postoperative 2 months follow up CT shows maintenance of reduction site. Gross depression of the forehead and visible scar was not observed. Conclusion: Although the indication of this procedure is limited, less aggressive, simple and very effective to the patient with simple. depressed, anterior frontal sinus fracture.

Background: Intraperitoneal (IP) and intrathecal (IT) administration of $\alpha$-amino-3-hydroxy-5-methyl-4-isoxazole-propionic (AMPA) and kainate (KA) receptor antagonist attenuate hyperalgesia in various models of persistent pain. The purpose of this study was to assess the effects of IP and IT LY293558, a novel AMPA/KA receptor antagonist on mechanical hyperalgesia after incision. Methods: Sprague-Dawley rats were anesthetized with halothane and underwent plantar incision. Two hours later, responses to mechanical stimuli were assessed using the response frequency to a nonpunctate mechanical stimulus and withdrawal threshold to calibrated von Frey filaments. One group of rats received vehicle, 5 or 10 mg/kg of LY293558 IP. In the other group, vehicle, 0.2, 0.5 or 2 nmol of LY293558 was administered IT. Ataxia and motor function were also evaluated. Results: Hyperalgesia was persistent in both the vehicle and 5 mg/kg group. IP administration of 10 mg/kg of LY293558 increased withdrawal threshold at 30 and 60 min after incision; deficits in rotorod performance were observed at 30, 60, 90 and 150 min. IT administration of 0.5 nmol of LY293558 increased the median withdrawal threshold at 30 and 60 min. Motor function was only impaired at 30 min. IT administration of 2 nmol produced hemiparesis. Again, inhibition of pain behaviors outlasted the effects on motor function. Conclusions: These data further suggest AMPA/KA receptors are important for the maintenance of pain behaviors caused by incisions. IT administration of LY293558 was more effective than systemic administration and reducing pain behaviors caused by a surgical incision.

This study compared the instrument performance and tissue healing of a steel scalpel with a $CO_2$ laser in an animal urinary bladder surgery model. Landrace and Yorkshire mixed breed pigs were used. Two symmetrical incisions were made in urinary bladder of each pig. One incision was made on the left side of ventral aspect on urinary bladder using a steel scalpel, while the other incision was performed on the right side using a $CO_2$ laser with an 8W output power. Each instrument was evaluated clinically for speed, ease of incision, and extent of bleeding. At 7 and 21 days after initial wounding, each wound was taken for histological observations. The scalpel was an easier instrument to use in the confines of the urinary bladder tissue, compared with the laser. However, there was no significant difference between the two groups. The amount of bleeding was less in the laser group but the time of the incisions was shorter with the scalpel. Scalpel incisions showed complete restoration of the epithelium and muscularis. On the other hand, the laser incisions showed incomplete restoration of the epithelium and muscularis. However, most of wound healing in the laser incisions was accomplished according to the time lapse. Although the scalpel produced less damage to the urinary bladder tissue and was easier to handle than the $CO_2$ laser, it did not provide hemostasis that was helpful for use on highly vascular tissue. The $CO_2$ laser provided good hemostasis, but delayed wound healing. In conclusion, the $CO_2$ laser provided better hemostasis and better surgical field than the scalpel. The $CO_2$ laser was used effectively in urinary bladder incision.

Objective : This study is aimed to assess the clinical outcome in early and minimally invasive surgery using incision for the patients with poor grade aneurysm. Methods : The authors retrospectively reviewed all 46 poor grade patients of Hunt and Hess[H-H] grade IV and V who suffered aneurysmal subarachnoid hemorrhage[SAH] between 1999 and 2004. All 35 patients harboring 43 aneurysms who underwent early surgery within 72 hours were included in this study. Clinical outcome was assessed by Glasgow outcome scale[GOS] and compared with that of conventional pterional approach. Results : Twenty four patients were operated with conventional pterional approach and 11 with eyebrow approach within 72 hours after SAH. Seven multiple aneurysm patients harbor 15 aneurysms, Forty one aneurysms were treated with clippings. All 11 patients of eyebrow surgery group[ESG] were in H-H grade IV, 3 in Fisher grade III and 8 in Fisher grade IV. Among 24 patients of pterional approach group[PAG]. 20 were in H-H grade IV and 4 in H-H grade V, 3 were in Fisher grade III and 21 in Fisher grade IV. Overall favorable outcome was achieved in 41.7% and 54.5% in PAG and ESG, respectively. Favorable outcome of H-H grade IV in PAG showed 45.0%. Overall mortality rate was 14.3%. Conclusion : It is concluded that the clinical outcome of early and minimally invasive aneurysmal surgery using eyebrow incision in the selected poor grade aneurysm patients can be compatible with that of conventional pterional surgery.

An one-year-old, female pointer dog with conjunctival hyperemia, corneal opaque and ocular pain in right eye was referred to Veterinary Medical Teaching Hospital, Chungbuk National University. In the ophthalmic examination the worm was observed in anterior chamber, The heart worm antigen test was positive. A modified Knott's test was negative. The values of complete blood count and serum chemistry (TP, BUN, creatinine, AST, ALT, ALP, albumin, globuline) showed normal ranges. Any abnormality was not detected in the heart using a thoracic radiography and cardiac sonography. Therefore, this dog was diagnosed as ocular filariasis. The worm was removed by surgical incision through a limbus of cornea. The closure of limbal incision was sutured in a simple interrupted suture pattern with 6-0 silk and the eye was reinflated with sterile saline solution. Antibiotics and dexamethasone ophthalmic solution were applied to right eye every 24 hours for 7 days. To prevent latent filariasis, ivermectin was also administered on day 14 of operation. The heart worm antigen test on day 60 was negative. The dog was successfully cured.
