  • Actiniarians were collected from the sandy mud flat of Deokjeokdo, Jak-yakdo, Yeoungjongdo and Hupo of Korean waters from 1962 to 1998. They are identified into three species of two families, which are newly recorded to Korean athenarian fauna: Synandwakiu multitentaculata n. sp., Edwardsioides japonica (Carlgren, 1931) and Metedwardsia akkeshi (Uchida, 1932). They are described in detail with figures and tables. Synandwakia multitentaculata n. sp. is easily distinguished from S. hozawai by having up to 200 in the number of tentacles and by the peculiar macrobasic amastigophores of tentacles and the larger microbasic p-mastigophores of acontia in the macrocnidae.

  • Metal ions contamination may inhibit microorganisms involved in the biodegradation of organic compounds and affect biodegradation rates. Therefore, it is likely that bioremediation of xenobiotics-contaminated soils and waste will require inoculation with efficient biodegrading microbial communities, with capabilities of being resistant to heavy metals as well. Two different transconjugants (Pseudomonas sp. KMl2TC and P. aeruginosa TC) were constructed by conjugation experiments. Results on MIC, induction and growth inhibition strongly indicated that arsenic-resistant plasmid, pKM20, could be mobilized, and the newly acquired phenotype of pKM20 was not only expressed but also well regulated, resulting in newly acquired resistances to $As^{5+},\;As^{3+},\;and\;Sb^{3+} in\;addition\;to\;Cd^{2+},\;Zn^{2+},\;and\;Hg^{2+}$. The phenol- degradation efficiencies of Pseudomonas sp. KMl2TC were maintained significantly even at high heavy metal concentrations at which these efficiencies of P. aeruginosa TC were completely impaired. The results in this study on the effects of heavy metals on phenol degradation, especially after conjugation, are the first ever reported. All the results described in this study encourage to establish a goal of making "designer biocatalysts" which could degrade certain xenobiotics in the area contaminated with multiple heavy metals.

  • Hemicycliophora litoralis is newly collected from Korea. Korean population is well matched and within a range of original description and additional record from Solomon island in de Man's of L, b, c, V, R, Rex, Ran, Roes, RV (ant), annule, excretory pore, stylet length, and tail length. Differences are observed in RV and RVan. RV and RVan of original description was 55 (48-69) and 14 (10-19) but Korean population is 68 (61-76) and 22 (19-24), respectively. H. litoralis described from Solomon island has RVan of 19.6 (17-23) and is similar to Korean population. H. litoralis from Solomon island has slight higher Rst value of 39 (35-59) compared to Korean population of 33.5 (29-38). The measurements of MB (%), s, G1, G2 values are newly given.

  • In the lepidopteran surveys in Mt. Changbai, China, during 2000-2003, 10 species of the genus Zanclognatha Lederer of Noctuidae were recognized. Of them, a new species, Zanclognatha lui sp. novo is described, two species (Zanclognatha umbrosalis Staudinger and Z. perfractalis Bryk) are reported for the first time from China, and four species (Z. fumosa, Z. lilacina, Z. violacealis and Z. tarsipennalis) are newly known from Mt. Changbai. Synonymies, distributional ranges, photos of the genitalia, and images of the new and newly recorded species are given.

  • Carchesium polypinum and Vorticella campanula were collected in freshwater ponds and reservoirs on Jindo Island and other places in Korea. These two vorticellids are newly recorded in Korea. The two species are described using live and silver impregnated cell observations, morphometry, line drawings, and microphotographs. Characterizations were based on the following diagnostic features: Carchesium polypinum was observed mainly as a funnel to fanshaped colony, basically dichotomous branching pattern, discontinuous spasmoneme, subconical shaped zooid, J shaped macronucleus, ventrally positioned single contractile vacuole, and pellicular striation with 61-80 rows between the peristomial lip and aboral ciliary wreath, and 18-30 rows between the aboral ciliary wreath and scopula. Vorticella campanula was conspicuously characterized by the broadly bulged peristomial lip, wide conical shaped zooid, J or S shaped macronucleus, ventrally positioned single contractile vacuole and pellicular striation with 64-75 rows between the peristomial lip and aboral ciliary wreath, and 27-41 rows between the aboral ciliary wreath and scopula. We provide redescriptions of two well-known vorticellids with detailed drawings and descriptions of oral ciliatures from Jindo Island and other places on the Korean peninsula.

  • Purpose: V.A.C. is a new concept which is closed dressing with negative pressure to promote wound healing. It has been widely used as the treatment of chronic and acute wounds such as pressure sores, burns, stasis ulcers, and other complicated wounds. However It has disadvantages such as high cost and the need of specific equipment. In this article, we described new method to overcome these disadvantages. Methods: We made newly innovated equipment with 50 cc syringe and spring to create negative pressure. From May 2006 to May 2007, we applied it to two patients with chronic wound. Results: The treatment period was 5 weeks for one case and 3 weeks for the other case. Both patients were healed completely without admission and wound healing was accelerated. During follow-ups, there were no complications. The mean cost for single dressing was 9,590 won. Conclusion: Modified portable negative therapy using newly innovated equipment could accelerate wound healing better than conventional dressing. It lowers the number of dressings, saves cost of treatment, and enables treatment as outpatient basis.

  • Five species of the Laboulbeniales are reported to the Korean mycoflora. They are Laboulbenia acupalpi Spegazzini on Acupalpus hilaris Tschitscherine, L. pseudomasei Thaxter on Anoplogenius cyanescens(Hope), Rickia peyerimhoffii Maire on Scaphidium femorale Lewis, Zodiomyces odae Majewski et Sugiyama on Sternolophus rufipes Fabr. and Z. vorticellarius Thaxter on Berosus fairmairei Zaitzev. Among these species L. pseudomasei Thaxter and Z. odae Majewski et Sugiyama are the first report to South Korea. L. acupalpi Spegazzini and Z. vorticellarius Thaxter found on species which are different from previous to host insects. R. peyerimhoffii Maire is newly described main land of Korea, although it was reported from Jeju island.

  • This study reports three species in the genus Tubastraea from Korea: Tubastraea coccinea Lesson, 1829; Tubastraea faulkneri Wells, 1982; and Tubastraea micranthus (Ehrenberg, 1834). Tubastraea faulkneri and T. micranthus are newly recorded in Korea. The specimens of three species were collected in the subtidal zones off Jeju-do between 1991 and 2010. The two newly recorded species were described in detail based upon the morphological characters of skeletal structures. The previous records of T. coccinea in Korea were supplemented with additional data in the remarks. These three species have a straight septal arrangement or irregular septal fusion in common as a main character for the genus Tubastraea, but they differ with respect to the growth form, intercorallite distance, exsertness from common coenosteum, and the detailed characters of septal arrangement. Tubastraea faulkneri is similar to T. coccinea in its plocoid growth form, well developed common coenosteum, and corallite size. However, unlike the latter species, the former species is characterized by rare or absent budding adjacent to the corallite edges, wider intercorallite distance, and irregularly developed septal fusion near the columella. In particular, T. micranthus is distinguished by an axial dendroid growth form, and the smallest corallites in this genus.

  • Herpes zoster oticus is one of complication of varicella zoster virus (VZV) reactivation in the geniculate ganglion of the facial nerve, which is the most common presentation of herpes zoster in the head and neck region. However, VZV infection of the larynx has rarely been described in the literature compared with Herpes zoster oticus. Moreover, zoster laryngopharyngitis simultaneously occurred with recurred Herpes zoster oticus which has no newly developing motor dysfunction has not been reported yet. Therefore, these diseases are difficult to diagnose due to its rareness. However, distinctive appearances such as unilateral herpetic mucosal eruptions and vesicles are useful and essential in making a quick and accurate diagnosis. Thus, we report a characteristic case of zoster laryngopharyngitis simultaneously occurred with recurred Herpes zoster oticus not accompanied by any newly developing motor palsy.
