Genus Cochylidia, belonging to the tribe Cochylini under the family Tortricidae, consists of small-sized moths, which is one of the small group with only 11 described species until now (Brown 2005; Sun & Li 2012). Recently, Brown (2005) listed eight species and one subspecies. Later, three species were added to the genus by Sun & Li (2012) from China. In Korea, Park (1976) reported the genus Cochylidia with three unrecorded species, C. contumescen Meyrick, C. richteriana Fischer von Röslerstamm, and C. subroseana Haworth from Korea. Later, Byun et al. (1996) reported two additional species from Korea: C. heydeniana Herrich-Schäffer and C. moguntiana Rösler. Recently Byun et al. (2017) reported the genus in Korea with two new species, C. flavifasciatus Byun and C. hallasanensis Byun. In this study, we provide the checklist with its external characteristics, localities, and images of adults and genitalia.

전기화상후 Prostaglandin F2a와 Thromboxane B2의 증가에 대한 Flurbiprofen, Prednisolone 및 Gabexate mesilate의 억제효과

조병채,김인규,변진석,백봉수 大韓成形外科學會 1991 Archives of Plastic Surgery Vol.18 No.1

This study was conducted to clarify the inhibitory effect of flurbiprofen, prednisolone, and gabexate mesilate on the synthesis of prostaglandin F2a and thromboxane B2 in the tissue of electrical burn. one hundred sixty Sprague-Dawley rats, 250gm of body weight in average, were divided into 4 groups of control, flurbiprofen, prednisolone and gabexate mesilate administred group. Fourty rats of the each group were subdivided into 1st, 2nd, 4th, 7th postburn day with 10 rats in each subgroup. Ten rats were used for normal values of prostaglandin F2a and thromboxane B2. Flurbiprodfen 30mg/kg was given per mouth, and prednisolone acetate 5mg/kg and gabaxate mesilate 50mg/kg were administred intramuscularly 5 minutes after burn injury and then once a day. All but bone tissue of within 2cm area of the current entry were harvested and ground into homogenate. The levels of prostaglandin F2a and thromoboxane B2 were measured by Radioimmunoassay. The results were as followings: In normal rat tissue, the level of prostagland F2a and thromboxane B2 were 15.8±1.8 and 17.6±2.8ng/mg protein in each. In the control group the levels of both prostaglandin F2a and thromboxane B2 increased abruptly to 5 times and 7 thimes in the first day and maintained the same level in the second day. After then they rapidly decreased and returned to a near normal level in the fourth day. The increase of thromboxane B2 was more remarkable than that of prostaglandin F2a. In the flurbiprofen group, the level of thromboxane B2 was not inerease but kept at a normal level. The average level of prostaglandin F2a in the post-burn first and second day was 59.5% lower than of the control group. The average level on the post-burn first and second day was 61% lower in thromboxane B2 and 33% lower in prostaglandin F2a in the prednisolone group, and 68% lower in throboxane B2 and 48% lower in prostaglandin F2a in the gabexate mesilate group, compared to the control group. These findings suggest that electrically injured tissue is vigrously progressive due to rapid increase of thromboxane B2 and prostaglandin F2a, as inflammatory mediators, in the post-burn first and second day, is nonprogressive after the post-burn fourth day. The flurbiprodfen was the most effective of the three drugs(flurbiprofen, gabexate mesilate, prednisolone in order of effectiveness) to suppress the synthesis of thromboxane B2 prostaglandin F2a of the electrieally injured tissue.

Three Newly Recorded Species of the Genus Olethreutes (Lepidoptera, Tortricidae) from North Korea

In North Korea, the Tortricidae has been poorly studied until Byun et al. (1998) reviewed 350 species from Korea, including 63 species of Tortricinae and 40 species of Olethreutinae. Then Razowski (1999) presented a checklist of 358 species of Tortricidae from Korea, including 176 species of the North Korean Tortricidae with mostly based on the avaialble materials in Poland and previous literatures. Later, a serial studies on the family Tortricdae of North Korea with the material deposited in the Hungarian Natural History Museum provided several additional data for the North Korean tortricid fauna (Byun 2009; Byun 2011a; Byun 2011b; Byun 2011c; Byun et al. 2007) During the course of the study on the Tortricidae of North Korea deposited in Hungarian Natural History Museum, the author found three species of Olethreutes for the first time from North Korea. Of them, Olethreutes aviana Falkovitsh is also newly reported to the Korean peninsula. The aim of the present study is to report the three species of Olethreutes as new to North Korean fauna. In the present study, three species of the genus Olethreutes: O. aviana Falkovitsh, O. obovata (Walsingham), and O. orthocosma (Meyrick), based on the material deposited in the Hungarian Natural History Museum, are reported for the first time from North Korea. Among them, O. aviana Falkovitsh is recorded as new to the Korean peninsula. Photographs of the adults and genitalia of the species are presented.

The first record of the subfamily Tortricinae from North Korea was reported by Zhu (1969), comprising 17 species. Later Park and Byun (1991) added 11 species of the subfamily. And Park and Razowski (1991) added 16 species of the tribe Tortricini. Jaros et al. (1992) reported 11 species of Tortricinae from North Korea, based on the material Czech Academy of Sciences, Prague, Czech Republic(CAS). Byun et al. (1998) enumerated 350 species of Korean Tortricidae, citing 63 species of Tortricinae and 40 species of Olethreutinae from North Korea. Later Razowski (1999) provided a list of Korean Tortricidae with 176 of North Korea. Despite these studies, much of the North Korean Tortricidae deposited in the HNHM remained unstudied. Recently the first author examined the totricid material in the HNHM and reported 7 newly recorded species from North Korea (Byun et al., 2007). In the present study, we provide the faunistic information for ten species of Tortricinae, including their localities. This study was carried out under the support of Korea National Arboretum and Korea Forestry Research Institute.
