  • The purpose of this study was to determine the effects of high voltage pulsed current (HVPC) stimulation on wound healing. Thirty-four Sprague-Dawley adult female rats were assigned to experimental and control groups. Each rats were anesthetized with pentotal sodium, and a 10 mm full-thickness incision was made on the back. From 24 hours after surgery, the rats of experimental groups were stimulated with HVPC, $140{\mu}s$, 120 pps, 30-40 V for 30 minutes, daily. The rats were sacrified 2 days, 4 days and 6 days after stimulation, respectively. The skin was removed, and processed for light microscopic examination. The length of incisional wounds were measured by microcaliper, and nucleolar organizer regions were counted under light microscope. For the histological observations the specimens were stained with Hematoxylin and Eosin, Masson Trichrome, Gomori Reticulum and Ag-NOR. There was a significant decrease in the length of incisional wound in experimental group compared with control group at 6 days HVPC stimuation (p<0.05). In experimental group, wound were significant difference (p<0.01) between the duration of post surgery. The mean numbers of nucleolar organizer regions per nucleus were significantly increased in the experimental group at 6 days HVPC stimulation (p<0.05), and were significantly difference (p<0.01) between the duration of post surgery in experimental group. Histological examination of the wound site suggested a more rapid of epithelialization and collagen formation between experimental groups compared with control groups. The result may indicated that the HVPC with $140{\mu}s$, 120 pps, 30-40 V for 30 minutes promoted surgical wound healing in the rat.

  • Stylopine is a major component of the leaf of Chelidonium majus L. (Papaveraceae), which has been used for the removal of warts, papillomas and condylomas, as well as the treatment of liver disease, in oriental countries. Stylopine per se had no cytotoxic effect in unstimulated RAW 264.7 cells, but concentration-dependently reduced nitric oxide (NO), prostaglandin E$_2$ (PGE$_2$), tumor necrosis factor-a (TNF-$\alpha$) and interleukin-1$\beta$(IL-1$\beta$), and the IL-6 production and cyclooxygenase-2 (COX-2) activity caused by the LPS stimulation. The levels of inducible nitric oxide synthase (iNOS) and COX-2 protein expressions were markedly suppressed by stylopine in a concentration dependent manner. These results suggest that stylopine suppress the NO and PGE$_2$ production in macrophages by inhibiting the iNOS and COX-2 expressions. These biological activities of stylopine may contribute to the anti-inflammatory activity of Cheli-donium majus.

  • A 65-year-old woman was admitted due to poor oral intake and a dry cough over the previous 3 months. The physical examination was remarkable for bibasilar crackles, and plain chest radiography showed reticulation in both lower lung fields. A pulmonary function test demonstrated a restrictive pattern with a reduced diffusing capacity of the lung for carbon monoxide. High resolution computed tomography showed reticulation and honey-combing in both peripheral lung zones, which was consistent with usual interstitial pneumonia pattern. Her skin showed livedo reticularis. The erythrocyte sedimentation rate and C-reactive protein level were elevated, and hematuria was noted on urinary analysis. A serologic test for auto-antibodies showed seropositivity for Myeloperoxidase-Anti-neutrophil cytoplasmic antibody (MPO-ANCA). A kidney biopsy was performed and showed focal segmental glomerulosclerosis. She was diagnosed as having pulmonary fibrosis with microscopic polyangiitis (MPA) and treated with high dose steroids. Here we report a case of pulmonary fibrosis coexistent with microscopic polyangiitis.

  • Eccrine poroma is a common benign cutaneous tumor that originates in an intraepidermal eccrine duct. This tumor exhibits acral distribution (sole, palm), and is rarely encountered in the head and neck area. In fact eccrine poroma in the postauricular area has only been rarely reported. A 55-year-old female visited our hospital with a main complaint of a mass that first developed in the left postauricular area about a year previously. The mass was painless, soft, protruding, domed, and dark red in color, and had slowly enlarged (at presentation it measured $1\times1cm$). Excisional biopsy was performed. Histological examination showed distinct features, and eccrine poroma was diagnosed. Follow-up at 6 months postoperatively showed no recurrence. The frequency of eccrine poroma is dependent on eccrine sweat glands density, and thus, usually occurs on the palms or soles. For eccrine poroma in the head and neck region, the differential diagnosis must rule out other masses, such as nevus, skin tag, pyogenic granuloma, cyst, basal cell carcinoma, and seborrheic keratosis. Importantly, 18% of poromas show malignant transformation, and can develop into porocarcinoma. For these reasons, an eccrine poroma in the facial area requires histological examination, complete excision, and follow-up.

  • Nevus sebaceus is a hamartoma of the sebaceous gland that occurs congenitally, from which various secondary tumors can arise with a prevalence of 5%-6%. Benign neoplasms commonly arise from nevus sebaceous, but they have a very low malignant potential. Two neoplasms may occasionally arise within the same lesion, but it is rare for three or more neoplasms to occur in a nevus sebaceus simultaneously. A 61-year-old male patient was admitted to our hospital for a $4cm\times2.5cm$ growing tumor in a verrucous form arising within a periauricular nevus sebaceus in the post auricle of the left ear that had developed 30 years earlier. The nodule was diagnosed as 3 different types of tumors: trichilemmoma, desmoplastic trichilemmoma, and basal cell carcinoma. To our knowledge, this is the first report of the coexistence of three different tumors arising from nevus sebaceous. It contain malignant neoplasm also. Surgeons should be aware of the need for close monitoring and early complete surgical excision of sebaceous nevus in order to improve patient outcomes.

  • A 12-year-old spayed female mixed-bred dog presented with nasal bleeding of 2 days duration and a skin nodule in the left flank. No abnormalities were found in coagulation profiles and blood pressure. Cytological evaluation of the nodule revealed numerous characteristic round organisms having a nucleus and a bar within macrophages and in the background, consistent with leishmaniasis. In vitro culture was unsuccessful but PCR of the nodular aspirate identified the organisms as Leishmania infantum, and the final diagnosis was canine leishmaniasis. No history of travel to endemic countries was noted. Because the dog had received a blood transfusion 2 years before the illness, serological screening tests were performed in all donor dogs of the commercial blood bank using the commercial Leishmania ELISA test kit, and there were no positive results. Additional 113 dogs with hyperglobulinemia from Seoul were also screened with the same kits but no positive results were obtained. To the best of the author's knowledge this is the first autochthonous case of canine leishmaniasis in Korea.

  • Allogeneic hematopoietic stem cell transplantation (HSCT) is considered the optimal curative treatment for acute myeloid leukemia (AML), but some patients develop bone marrow relapse due to remnant leukemia, and few patients develop extramedullary relapse without bone marrow relapse. Isolated extramedullary relapse (IMER) is defined as extramedullary relapse without bone marrow relapse. IMER has been reported in various sites, including the skin, soft tissue, and central nervous system(CNS). Isolated CNS relapse is relatively rare and is associated with poor prognosis due to the absence of an optimal treatment for it. Reported herein is a case involving an adult AML woman who suffered from isolated extramedullary relapse in the CNS after allogeneic HSCT. She was treated with intrathecal chemotherapy and whole-brain and spine radiotherapy, followed by systemic chemotherapy. She is currently well, with no evidence of leukemia recurrence for over six years.
