이명렬,안성복,조왕수 한국응용곤충학회 2000 한국응용곤충학회지 Vol.39 No.1

임의증폭 다형 DNA(RAPD)와 미토콘드리아 12S, 16S rRNA 유전자의 제한단편 DNA 표식자에 의해 한국에서 발생하는 담배가루이 개체군들의 biotype을 판별하였다. 진천의 장미 온실과 서울 내곡동의 포인세티아 온실에서 발생한 담배가루이는 일본, 이스라엘, 호주의 B biotype 과 동일한 DNA 단편들을 보유하였다. 여러 지역의 노지 콩 (Glycine max), 고구마 (Ipomea batatas), 들깨 (Perilla frutescens)에서 채집된 담배가루이 개체군들은 일본 시코쿠의 인동덩굴(Lonicera japonica)에서 채집된 담배가루이와 같은 DNA로 표식되었다. 이들 non-B biotype은 한국, 일본 등 극동아시아 지역에 고유한 계통으로 보인다. 최근 한국에서 발견된 담배가루이 Bemisia tabaci(Gennadius)의 주사전자현미경 관찰에 의한 형태적 특정을 온실 원예작물의 주요해충인 온실가루이 Trialeurodes vaporariorum (Westwood)와 비교하여 기재하였다. The sweetpotato whiteflies, Bemisia tabaci(Gennadius), were found recently in Korea on Glycine max, Euphorbia pulcherrima, and Rosa hybrida. The biotype identity of Bemisia tabaci in Korea was determined by several DNA markers including the random amplified polymorphic DNAs, and restriction fragments length polymorphism of mitochondrial 12S and 16S rRNA genes. The electromorph profiles of DNA fragments from the rose(Jincheon) and poinsettia(Seoul) populations in Korea are both identical to those of B biotypes distributed in Australia, Israel, and Japan. The populations of B. tabaci collected on Glycine max, Ipomea batatas, and Perilla frutescens in different localities retained the same DNA markes with the population from Lonicera japonica and shikoku of Japan. These populations are non-B biotype and considered as an indigenous type in the Far Eastern Asia Region including Korea and Japan, Morphological Characteristics of B. Tabaci were also observed by the scanning electron microscope and described with the comparison to the other important whitefly pest, Trialeurodes vaporariorum (Westwood).

양봉산업 연구동향 - 벌들의 귀환

이명렬,Lee, Myeong-Ryeol 한국양봉협회 2009 양봉협회보 Vol.342 No.-

세계적 경제주간지 '이코노미스트(Economist)'는 3월 5일자 과학기술 섹션에서 '벌들의 귀환(The bees are back in town)'이라는 제목의 기사를 내보냈다. 작년도까지 전세계 양봉업계에 충격을 던져주었던 꿀벌의 실종 또는 봉군의 붕괴현상(CCD; colony clollapse disorder)에 대한 공포로 모두가 긴장하고 잇는 가운데, 붕괴되거나 사라졌던 벌이 다시 돌아왔다는 사실에 세계 양봉산업계가 안도하는 분위기이다. 이에 양봉협회보에 벌의 귀환 배경을 간략히 소개하고자 한다. 보는 관점에 따라 다른 해석도 가능하다는 점을 부언하고자 한다.

임프란트 식립을 위한 치조정과 상악동 및 비강저간의 거리에 관한 연구

이명렬,심광섭,유광희 대한치과이식임플란트학회 1996 The Korean Academy of Implant Dentistry Vol.15 No.1

In dental implantation, comprehension on the anatomy of maxillae, mandible and its surrounding structures is very important, and this can also determine success or failure of the operation. The author measured the distance with a caliper from alveolar crest to the floor of maxillary sinus and nasal cavity on the traced paper of orthopantomograms. For this study, the author selected 320 orthopantomograms of normal adults and divided the cases into 8 groups by age and sex ; group I (20-39,male), group II (20 — 29, female), group III (30—39, male), group IV (30—39, female), group V (40—49,male), group VI (40—49,female), group VII (above 50,male), group Vffl (above 50, female). The results were as followed. 1. In the maxillae, the maximum and minimum distance between the floor of maxillary sinus and alveolar crest of 3rd molar area was 16.74± 2.53mm and 7.83± 2.81mm, respectively. In the 2nd molar area, maximum was 14.69+ 4.04mm and minimum was 8.45± 2.16mm, and in the 1st molar area, maximum was 14.34± 2.45mm and minimum was 7.24士 2.15mm. In the 2nd premolar area, maximum was 19.19土 2.62mm and minimum was 12.53± 3.41丽, and in the 1st premolar area, maximum was 23.50± 2.46mm and minimum was 14.87 ± 3.07 mm. 2. The maximum and minimum distance between the floor of nasal cavity and alveolar crest of central incisor area was 35.50± 2.02mm and 26.58± 2.88mm, respectively. In the lateral incisor area, maximum was 34.33± 2.85mm and minimum was 25.23± 2.46mm. 3. No significant difference was shown by comparing left and right side of each group. 4. In comparing each sex, classified by age, no significant difference has been shown in their twenties and thirties, but more amount of resisdual alveolar bone of maxillae has been shown in female group than in male group in their late of forties. 5. As aging, residual alveolar bone of maxilla is reduced due to alveolar bone resorption and pneumatization of maxillary sinus.

The Study of Age-related Skin Pigmentation Changes in Korean Female

이명렬,정유철,서병휘,김은주 사단법인 대한화장품학회 2023 대한화장품학회지 Vol.49 No.2

Since facial skin pigmentation is one of the visual characteristics of skin aging, it is important to evaluate skin pigmentation in the cosmetics and aesthetic fields. Several groups have investigated and developed the image analysis methods for skin pigmentation and some of the groups reported the age-related changes of the number and size of facial pigmented spots. However, they didn’t show the changes of the number and size of pigment spots by defined size, and there is no report for Korean female regarding pigmentation. A total of 194 Korean females aged 20 ~ 79 (48.97 ± 17.11 years) were analyzed for the number, size, and intensity of pigmented spots using various filters such as large high-pass filter and median filter in their digital facial images. There were significant correlations between age and total pigmented spot number (No.), size, and intensity (I) (pearson’s correlation coefficient r = 0.688, r = 0.645, r = -0.563), and significant correlations were also observed between the number and intensity of pigmented spots of different sizes. According to the ANOVA results, there were significant differences in the percentage of spot size of 2 ~ 4 mm2 and > 20 mm2 between 20’s and 70’s. In other words, with aging, pigmentation increases in the facial skin, and the large increase in pigmentation is particularly noticeable in Korean women.

죽력(Bambusae Caulis in Liquamen)이 고지방이식이를 급여한 흰쥐의 체내 지질대사에 미치는 영향

이명렬,하진옥,추명희,나명순,최현숙 한국식품저장유통학회 2004 한국식품저장유통학회지 Vol.11 No.3

The purposes of this study were to investigate effects of Bambusae Caulis in Liquamen(BCL) on antioxidant activities and inhibitory activities of HMG-CoA reductase of in vitro, and lipid metabolism in rats fed the high cholesterol diet in vivo. Sprague-Dawley male rats weighing 100±10 g were devided into five groups ; normal group(NOR), the high cholesterol diet administered group(1% cholesterol and 0.25% sodium cholate)(CON), 5% BCL administered group (5BL), the high cholesterol diet and 5% BCL administered group (5BCB) and the high cholesterol diet and 10% BCL administered group (10BCB), respectively. In antioxidative activities of BCL using Rancimat in vitro, 1.25 diulent and original solution were more excellent activities than the control group, and in inhibiting activities of HMG-CoA reductase, BCL was shown inhibitory effects compared with the control, in dose dependent manners, especially 57.9% in original solution and 36.0% in 1.25 diulent. The growth rate of the control group was higher than the normal group, wheras the group given 5% BCL and 10% BCL were gradually decreased, especially the most excellent effect in 10% BCL. Serum levels of total cholesterol, LDL-cholesterol, triglyceride and free cholesterol were significantly decreased, whereas levels of HDL-cholesterol and phospholipid were increased, but not significantly. BCL administered group was increased in HDL-cholesterol/total cholesterol ratio and lowered antherogenic index. The activities of AST in serum were rather lowered in the BCL administration group than the cholesterol diet group, but not in ALT and ALP. The hepatic contents of total cholesterol were lowered significantly than control group, but not in triglyceride. Therefore, it might be expected that BCL is believed to be a possible protective or curative effects for fatty livers and hyperlipidemia-induced by a high cholesterol diet.
