  • Processing of medicinal plants is one of the processing methods for reducing of toxicity or improving of effect on medicinal plants. In this study, we studied the changes in the constituents and antioxidant activity in accordance with the processing conditions by the salt water of Citrus unshiu Markovich. Changes in antioxidant activity was measured by the DPPH method and changes in the components were analyzed by high performance liquid chromatography. As a result, the content of the main constituents (narirutin, hesperidin) and total polyphenol were increased by increasing the concentration of salt water. Moreover, antioxidant activity was increased gradually in proportion to the increase of the total polyphenol content.

  • The findings of this study into the quality of fresh pasta noodles containing different amounts of the lyophilized citrus peel powder are as follows. The higher the amount of the citrus peel powder in the pasta, the higher was its WRC. The Hunter's values, whether L, a, and b all increased in both cooked and raw noodles. The higher the amount of the citrus peel powder, the less the level of tensions and the lower the setback values. These results suggest that the citrus peel powder might have a controlling effect on retrogradation. As for the characteristics of cooked pasta noodles, the weight decreased; the volume increased; and the moisture absorptive power also increased. The tasters' preferences were in the following order: 3%>0%>5%>7%>1%. In other words, a citrus peel powder content of 3~5% appears to be most appropriate.

  • Objective : This experimental study was performed to investigate the effect of Jinpi-san on Staphylococcus aureus(S. aureus) and Staphylococcus epidermidis(S. epidermidis) that induce keratitis. Methods : Minimal inhibitory concentration(MIC) was measured by dropping to $50{\mu}l$ according to density Jinpi-san(100%, 10%, 1%, 0.1 %). Anti-bacterial potency was measured by the size of inhibition zone with change of volume. Results : 1. MIC on S. aureus in Jinpi-san was $40{\mu}l$ undiluted solution. 2. MIC on S. epidermidis in Jinpi-san was $20{\mu}l$ undiluted solution. Conclusions : These results indicate that Jinpi-san can be used to cure S. aureus, S. epidermidis that induce eye disease(keratitis). If further study is performed, the use of eye drops will be valuable and beneficial in the clinical medicines.

  • Dendritic cells(DC) are a system of highly efficient antigen-presenting cells that initiate the primary immune response. There are two kinds of dendritic cells in the skin, Langerhans cell in the epidermis and dermal dendritic cell in the dermis. The knowledge of DC, which are very important in the immune reponse of cancer, autoimmune disease, transplantation and infection, has been known through the study about Langerhans cells. In this paper, the role of Langerhans cell in the contact hypersensitivity and atopic dermatitis is discussed and culture methods of mouse Langerhans cells and human U from pheripheral blood monocytes are described.

  • The most common surgical repair method for fingertip injuries are replantation, flap coverage, and skin graft. In fingertip injury cases, acellular dermal matrix (ADM) is generally used in a two-stage operation. In the present case, only ADM was used in a 67-year-old male patient with a right fifth fingertip injury. The patient was undergoing chemotherapy after surgery for colon cancer, preventing prolonged hospitalization. In addition, wound healing was likely to be problematic. As a typical surgical method might have been difficult to apply in such a patient, we performed a one-stage operation, using only ADM on the injured area. Postoperative followup for 3 months showed good wound healing. Accordingly, we report a successful treatment outcome using ADM alone for a fingertip injury.

  • In recent decades, tissue engineering advances have led to more skin substitutes becoming available. Acellular dermal matrix, initially developed for use in the treatment of full-thickness burns, is made by removing the cellular components from the dermis collected from donated bodies or animals. This class of scaffold is used to replace skin and soft tissue deficiencies in a variety of fields, including breast reconstruction, abdominal wall reconstruction, and burn treatment. Herein, we provide a detailed review of the clinical applications of acellular dermal matrix.

  • Clear cell hidradenoma is a tumor that originates from a sweat gland and typically involves the dermis and subcutaneous tissue. Malignant clear cell hidradenoma is very rare, and surgical excision is usually performed without imaging. There are few reports of the ultrasonographic findings of malignant clear cell hidradenomas. Herein, we present the ultrasonographic characteristics of a malignant clear cell hidradenoma.

  • Commonly, epidermal inclusion cysts (EICs) are benign cutaneous lesions that are lined with stratified squamous epithelium and may occur in all body parts, including the breasts. EICs in the breast (EICB) are commonly encountered clinically; it may be under-reported because of their mild and nonspecific clinical presentation. Malignant transformation of EICs is extremely rare, occurring 0.011%-0.045%. Presently, we report a rare case of squamous cell carcinoma arising from an EICB of a woman with invasive ductal carcinoma.

  • This study was carried out to investigate the total polyphenol and flavonoid contents and antioxidative activities of enzymatic digests from dried Citrus unshiu and C. grandis peels. The yields of digests from dried C. unshiu and C. grandis peels were high in viscozyme (a carbohydrase) and kojizyme (a protease), and enzymatic digests from dried C. grandis peels appeared highly comparable to those of C. unshiu. Total polyphenol contents were high in ultaflo (a carbohydrase) and alcalase and flavourzyme (proteases), and the digests from dried C. unshiu peels appeared high in comparison to C. grandis. Total flavonoid contents were high in ultaflo, alcalase, and water extract. DPPH radical scavenging activities appeared very high in digests from dried C. grandis peels in comparison to C. unshiu, and was the highest in viscozyme and kojizyme. The viscozyme digest displayed particularly high activity. Hydrogen peroxide scavenging activities increased somewhat with increasing amounts of digests, but displayed very high activity, more than 91%, except kojizyme the digest from dried C. unshiu peel, at 2.0 mg/mL. Alkyl radical scavenging activities increased rapidly with increasing amounts of digest, and all enzyme digests from dried C. unshiu and C. grandis peels displayed very high activities at more than 0.5 mg/mL. Hydroxyl radical scavenging activities increased rapidly with increasing amounts of digests, and all enzymatic digests from dried C. unshiu and C. grandis peels displayed relatively low activities in comparison to other activated oxygen species.

  • Since the summer of the year 1972 ulcer disease of common carp, colour carp ana goldfish had suddenly spread widely and caused a serious mortality at fish farms especially around Gim-hae and Yang-san, near Busan. The present study aimed to find out the causative organisms, histopathological changes and the way of treatment, and the results are summarized as follows : Two kinds of pathogenic bacteria, i. e, Chondrococcus columnaris and Aeromonas sp. were isolated from the mucus of the lesion. According to the macroscopic findings, these symptoms began with the hemorrhagic spots under scales which fell out, after the collapse of the dermis, which was followed by lesion to form ulcer, and then the muscle was exposed. The fin was eroded mostly from the distal part, but sometimes from the basal part. Gills showed grey colour, and this part of the tissue collapsed. According to the histopathological findings, the dermis was exposed after the collapsed of the epithelium of the skin, and the necrosis of the musculature occurred, the muscular fibre being destroyed. The epithelial cells of gill tissue proliferated, thus gill filaments were conglutinated and collapsed. Fatty degeneration happened at the liver but the other organs seem to be normal. Treatment with the following mixtures were effective the water temperature of $22\~25^{\circ}C$, but not effective when the temperature was under as low as $13\~15^{\circ}C$. Mixture 1. Aivet (HB-115.HCI) 0.3ppm Malachite green 0.2ppm. Dipterex 0.4ppm Mixture 2. Furanace (P-7138) 0.05ppm Malachite green 0.2ppm Dipterex 0.4ppm When lesion healed, the epithelium, dermis, and the muscular fibre were regenerated.
