Isolation of Rhizobacteria in Jeju Island Showing Anti-Fungal Effect against Fungal Plant Pathogens

To select active bacterial strains to control plant diseases, 57 bacterial strains were isolated from the rhizosphere of the plants growing in various areas such as coast, middle and top of Halla Mountain in Jeju Island. Anti-fungal effect of isolated bactrial strains was tested in vitro by incubating in potato dextrose agar with isolates of four fungal plant pathogens Rhizoctonia solani, Fusarium oxysporum, Colletotrichum gloeosporioides and C. orbiculare, respectively. Thirty-four bacterial strains inhibited the hyphal growth of the plant pathogens, from which 17 strains inhibited one of the tested fungi, 10 strains two fungi, six strains three and a strain TRL2-3 inhibited all of the tested fungi. Some bacterial strains could inhibit weakly the hyphal growth of the plant pathogens, whereas some did very strongly with apparent inhibition zone between the plant pathogens and bacterial strains indicating the unfavorable condition for hyphal growth. Although there was no apparent inhibition zone, some bacterial strains showed a strong suppression of hyphal growth of plant pathogens. Especially, the inhibition by TRL2-3 was remarkably strong in all cases of the tested plant pathogens in this study that could be a possible candidate for biological control of various plant diseases.

A Case of Primary Lumbar Epidural Lymphosarcoma: Case Report

Round cell sarcomas involving spinal epidural space such as Hodgkin's disease, plasma cali sarcoma reticulum cell sarcoma and lymphosarcoma are well known diseases. Of those, primary lymphosarcoma arising at spinal epidural space has been reported as the very rare disease by Bucy and other authors. The clinical pictures of the disease were presented by the compression of the spinal cord or cauda equina. If the condition treated promptly and properly with surgery and radiation therapy, the outlook would be good both for recovery and life in most instances. We have experienced a case of primary lymphosarcoma involving lumbar spinal epidural space in a 13 year-old male and obtained a good result after surgery and radiation therapy.

A Case of Carotid Cavernous Fistula Treated by Muscle and Polyurethane Foam Embolization: Case Report

There have been various surgical methods to treat the carotid cavernous fistula such as the carotid ligation, trapping procedure, embolization with muscle, gelfoam and polyurethane foam, balloon technique and direct transcavernous approach. Each method has its own merits and disadvantages. The ideal treatment of the illness would be the selective closure of the fistula with preservation of carotid patency. The authors are reporting a case of C-C fistula in which selective muscle embolism preserving carotid flow was attempted at first, but the closure was incomplete that polyurethane foam embolization was done in addition with success.
