These studies were conducted to find the effects of laser ablation OTR film types on MA package in perilla leaf, rape, pak choi and chicory sort of leaf vegetable. They were treated at two different temperature conditions and storage for 7 days, except the rape 25℃ treatment, which was stored for 5 days with four types of laser ablation film such as 3,000 cc, 5,000 cc, 7,000 cc and 10,000 cc/m2·day·atm films for perilla leaf and pak choi, 10,000 cc, 20,000 cc, 30,000 cc and 40,000 cc for rape, as 5,000 cc, 7,000 cc, 10,000 cc and 20,000 cc for chicory. In the all treatments, fresh weight loss rate was lower than 0.8% in 12℃, 1.6% in 25℃ except for the 10,000 cc film of perilla leaf. In the carbon dioxide contents, perilla leaf was maintained at the lowest in 12℃ and 25℃ for 10,000 cc, rape was maintained 3-4% in 30,000 cc and 40,000 cc at 12℃, and more than 6% in all film when finish stored at 25℃, pak choi was maintained about 5% except for the 3,000 cc film in 12℃, and chicory was showed average 3% that slightly higher at 12℃ in the 20,000 cc and increase more than 12% at 25℃ in all treat films. Ethylene content tended to be low with higher gas transmission film, but rape treated with the 10,000 cc and pak choi treated with the 3,000 cc film showed low content than average. It was considered that high carbon dioxide and low oxygen content inhibited ethylene occurrence. Rape was highly damaged by yellowing, but perilla leaf cleared. The 5,000 cc film at 12℃, 7,000 cc film at 25℃ for perilla leaf and the 10,000 cc film at 12, 25℃ for rape and 3,000 cc film at 12, 25℃ for pak choi and the 20,000 cc film at 12℃, 5,000 cc film at 25℃ for chicory had the best visual quality through panel test. In the off-flavor, the 7,000 cc film at 12, 25℃ for perilla leaf and 20,000 cc film at 12, 25℃ for rape and 7,000 cc film at 12℃, the 3,000 cc film at 25℃ for pak choi and 5,000 cc film at 12, 25℃ for chicory showed the best results. The conclusion was 5,000 cc and 10,000 cc films were the best film for MA storage at 12℃ and 25℃ in perilla leaf because it showed the best quality of visual quality and off-flavor. In the case of rape, 12℃ treatment was better than 25℃, and the 10,000 cc film showed the best results in carbon dioxide contents and off-flavor. In pak choi, the 3,000 cc film treatment was better than other films at off-flavor, carbon dioxide and visual quality for 12℃ MA storage, and the 10,000 cc film treatment was better than other films at off-flavor and visual quality. The 20,000 cc firm was the most reasonable treatment in both storage temperatures for chicory.
JUVENILE ACTIVE OSSIFYING FIBROMA 의 치험례
최인,Choi, In 대한악안면성형재건외과학회 1991 Maxillofacial Plastic Reconstructive Surgery Vol.13 No.2
Ossifying fibroma is a rare benign tumor of the maxilla and the mandible. And its nosology and diagnosis have had many problems. It occurs more common in young adult, especially in female, and there is a predilection for the mandible. The lesion is generally asymptomatic and recurrence is rare after conservative excision. Among ossifying fibroma, juvenile active ossifying fibroma grows rapidly, produces many symptoms, and frequently recurs after conservative excision. Authers experienced a case of juvenile active ossifying fibroma which recurred after two times of conservative surgery, and report is with review of the literatures.

칠레산 Alstroemeria 속 식물 종자에 저온층적처리로 인해 종자 휴면 타파하여 발아율에 미치는 영향을 알아보기 위해 이 실험을 수행하였다. 칠레산 Alstroemeria 속 식물은 나자은 발아율과 발아의 균일도가 떨어지는데, 층적처리는 많은 야생화에서 발아율과 균일도를 향상시킨다고 알려져 있다. 총 14종의 칠레산 Alstroemeria 속 식물 종자를 4±1℃에서 각각 20일과 40일 저장한 후 상온(20℃)에서 30일간 발아율, T50과 T75- T25을 조사하였다. 무처리구에서는 Alstroemeria philippii와 Alstroemeria wedermaniii var. flavicans이 각각 2%와 0.6%의 최종 발아율 (G30)를 보였을 뿐, 나머지 12종 모두 발아하지 않았다. 저온층적 처리는 총 7종에서 발아 촉진 효과를 보였는데, 20일 저온층적처리구(CS20)은 Alstroemeria magnif. var. magnif만이 5%의 G30을 보였으며, Alstroemeria diluta chrysantha, Alstroemeria exerens, Alstroemeria niagnif. var. tofoensis, Alstroemeria wedermaniii var. flavicans의 4종은 40일 저온층적처리구(GS40)에서 5%, Alstroemeria ligtu incarnata 는 10%의 G30을 나타내었다. 무처리구에서 2%의 발아율을 보인 Alstroemeria philippii는 CS20에서는 15%, CS40에서는 20%의 G30을 나타냈다. 이들을 제외한 나머지 7종의 Alstroemeria aurea var. red, Alstroemeria aurea color type orange, Alstroemeria presliana, Alstroemeria pulchra, Alstroemeria umbellata, Alstroemeria shizanthoides와 Alstroemeria leporina는 치상 후 30일 동안 발아하지 않아 저온층적처리에 대한 효과는 없었다. 저온층적처리로 눈에 띄는 발아율 향상을 가져온 Alstroemeria philippii의 T50은 CS20에서 무처리구의 17.5%로 낮아 높은 발아세를 보였으며, T75- T25은 20%의 발아율을 보인 CS40에서 보처리구의 30.3%를 보여 높은 발아 균일도를 보였다. 이를 종합해 보면 칠레산 Alstroemeria 속 식물 종자의 저온층적 처리에 의한 발아 촉진 효과는 일부 종에서만 인정되었으며, 보다 높은 발아율과 균일도를 위해서는 다양한 온도처리가 필요할 것으로 판단된다. The effects of cold stratification on the germination of Chilean Alstroemeria species were studied. Chilean Alstroemeria species showed low germination rate and lacked germination uniformity without any treatments. A cold stratification treatment was known to improve the germination rate and uniformity of many wildflower species. In this studies, 14 species of Chilean Alstroemeria seeds were treated cold stratifications that stored at 4 ± 1℃ for 20 days (CS20) and 40 days (CS40). Total germination rate after 30 days (G30), days to 50% germination (T50), and number of days between 25% and 75% final germination (T75-25) were calculated for each treatment. In non-treated seeds, Alstroemeria philippii and Alstroemeria wedermaniii var. flavican showed only 2% and 0.6% of G30, respectively, whereas the others did not germinated. A G30 was most significantly improved up to 5% by CS40 in 4 species; Alstroemeria diluta chrysantha, Alstroemeria exerens, Alstroemeria magnif. var. tofoensis, Alstroemeria wedermaniii var. flavicans. And Alstroemeria ligtu incarnate increased the G30 up to 10% by CS40. However the G30 of Alstroemeria magnif var. magnif was increased to 5% by CS20. Alstroemeria philippii that showed only 2% of G30 in non-treatment was increased G30 remarkably in CS20 and CS40 treatment up to 15% and 20%, respectively. But the cold stratification treatments did not show any improved effect on G30 in the other species that were Alstroemeria aurea var. red, Alstroemeria aurea color type orange, Alstroemeria presliana, Alstroemeria pulchra, Alstroemeria umbellata, Alstroemeria shizanthoides and Alstroemeria leporine. In Alstroemeria philippii that showed remarkable improved effect on G30, the germination speed increased by CS20 that was 17.5% of T50 compared with non-treated seeds and CS40 enhanced the germination uniformity because T75-25 of CS40 was just 30.0% of non-treated seeds. Therefore, the cold stratification showed partly improved effect on the germination of Chilean Alstroemeria species, and so various temperature treatments should be carried out for improving the germination rate and germination uniformity.
