OBJECTIVE: The objective of this study was to evaluate the effect of nasal packing, septal suture technique and vacuum sealing drainage (VSD) after septoplasty. METHOD: Ninety patients of nasal septal deviation in Combination with outfracture of the inferior turbinates who had received septoplasty were selected in this study. The patients were allocated into three groups, with thirty in each: for packing group, marcel materials were used for nasal packing after septoplasty; for suturing group, septal suture technique was performed after septoplasty; for VSD group, one drainage tube was used for negative pressure sucking after septoplasty without nasal packing. Postoperative signs and symptoms were compared between three groups. The comfort degree assessment included headache and nasal obstruction were evaluated by using visual analogue scale (VAS) at the 12th hour and 24 hour after operation. The edema in nasal cavity, hemorrhage. abscess,adhesive and healing rates after operation were compared among three groups. RESULT: The VAS score of headache and nasal obstruction and the severity of patient's conditions were significantly less in septal suture group and VSD group than that in packing group at the 12th and 24th hour after operation. The mucosa edema of nasal cavity was significantly slighter in septal suture group and VSD group than that in packing group at the third day after operation. The healing rates and number of complications are better in septal suture group and VSD group than those in packing group at the 7th day after operation. There were no hemorrhage or abscess in VSD group. CONCLUSION Septal suture technique and VSD after septoplasty can significantly relieve the distress of patients and reduce the healing time of mucosa in nasal cavity without increasing the risk of complications.

This study was aimed at evaluating the growth promoting effect of symbiotic algal polyol (ribitol) and plant hormones on the lichen-forming fungi (LFF), Ramalina farinacea (CH050010 and 40403) and Ramalina fastigiata. The addition of ribitol to basal (malt-yeast extract) medium enhanced the relative growth rates of all three LFF. R. farinacea (CH050010), R. farinacea (40403) and R. fastigiata (H06127) showed 35.3%, 29.0% and 29.3% higher growth rates, respectively, compared to the control. IBA (indole-3-butyric acid) and TIBA (2,3,5-tridobenzoic acid) also increased growth rates of the LFF by 34 to 64% and 7 to 28%, respectively, compared to the control. The combination of ribitol with IBA or TIBA synergistically increased the growth of all LFF. For example, ribitol and IBA treatments increased growth rates of R. farinacea (CH050010), R. farinacea (40403) and R. fastigiata (H06127) by 79.4%, 40.3% and 72.8% in, respectively, compared to those grown on the basal medium. The stimulating effect of ribitol and IBA on the LFF growth induced vertical development of the fungal mass in culture. We suggest that lichen-forming fungal growth of Ramalina lichens can be stimulated aposymbiotically by supplementing polyols and plant hormones to the basal medium in the mass production of lichen secondary metabolites under large scale culture conditions.

This study describes two new records of the lichen genus Placynthiella (P. hyporhoda and P. icmalea) from South Korea. A brief taxonomic description and comments are provided for the new records. An artificial key is also provided for known species of this genus in South Korea.

Lobaria (Schreb.) Hoffm is a common foliose lichen genus found on the Korean Peninsula, yet until now, no revision study has been done on this genus. After careful examination of specimens deposited in the Korean Lichen Research Institute (KoLRI), nine distinct species of Lobaria were confirmed. Morphological characteristics such as the presence or absence of isidia, or whether or not the surface was ridged or smooth, and chemical characteristics such as the result of the medulla reaction were of significant importance in the differentiation of species. Here, we provided detailed descriptions together with a key to all the known Korean species.

This study describes a new record of a thelotremoid lichen (Leucodecton desquamescens) from South Korea. The taxon is characterized by thick, bulging thallus with many calcium oxalate crystal inclusions; an immersed, round to irregular ascomata with free exciple, ellipsoid to +/- roundish submuriform, brown ascospores, and lack of secondary metabolites. A detailed taxonomic description and comments are presented for this taxon. The lichen genus Leucodecton is reported for the first time in South Korea.

Based on a literature survey and assessment of the important features of lichen genus Buellia (spore shape and size, anatomy of the exciple as well as analysis of the lichen substances), the present paper describes four new records of B. maritima, B. polyspora, B. spuria and B. stellulata from South Korea. Among them, B. maritima and B. polyspora are firstly reported in East Asia including in China, the Korean Peninsula and Japan. Brief description of all the new records along with earlier described species placed under genus Amandinea and Hafellia are provided with their distribution and chemistry. A key to all the Buellia species reported so far from South Korea is also provided.

In previous studies investigating the genus Xanthoparmelia, thirteen different species have been reported from South Korea alone. However, there currently has been no revisional study performed until now. To explore the genus Xanthoparmelia, a phenotypic analysis was performed based on morphological, anatomical and chemical characters, while an investigation of Xanthoparmelia phylogeny was based on nuclear ribosomal (nr) DNA ITS sequences. A thorough examination of the specimens deposited in the Korean Lichen Research Institute (KoLRI) confirmed that eight species of Xanthoparmelia occur inside South Korea. Our analysis further confirmed the colors of the lower surface and medullar chemistry are important taxonomic characters in Xanthoparmelia. This study also presents a detailed description of each species and a key to the genus.

Heterodermia squamulosa (Degel.) W.L. Culb. was found in the mountain of Gariwang, Gangwon province, in 2008. It is characterized by numerous squamules along the margin, decorticate and white lower surface, rhizines along the margin, black and densely squarrosely branched, usually forming a dense mat under the thallus. Apothecia margins densely squamulose, ascospores 12~15 x 25~30 microm. Atranorin and zeorin contained in thallus. This is the first record of this species in South Korea.

Myelochroa (Asahina) Elix & Hale is a common foliose lichen genus found on the Korean Peninsula. Since it was first recorded nearly two decades ago, no detailed taxonomic or revisionary study of the genus has been conducted. Thus, the current study was conducted to carry out a detailed taxonomic and revisionary study of Myelochroa in South Korea. This study was based on specimens deposited in the Korean Lichen Research Institute (KoLRI). Detailed taxonomic studies and a literature review confirmed the presence of twelve species of Myelochroa from S. Korea, including one new record, Myelochroa xantholepis (Mont. & Bosch) Elix & Hale. Descriptions of each species with their morphological, anatomical and chemical characters together with a key to all known Myelochroa species are presented.
