The octadodecanoxy derivative of the phthalocyanine which has such long hydrocarbon chains around the skeleton of the phthalocyanine was synthesized. First of all, ortho-catechol was treated with 2 moles of 1-bromododecane to yield ortho-didodecanoxybenzene(I). Second, bromination of I resulted in dibromo-didodecanoxy benzene(II) where the para positions to the dodecanoxy groups were brominated. Finally, reaction of II with an excess of CuCN under an N₂atmosphere gave the intermediate dicyano-didodecanoxy-benzene(III), in situ, and futher heating in dry DMF with more CuCN gave the final product, octadodecanoxy derivative of the phthalocyanine. The synthetic method developed herein provides a general way to synthesize the variety of the phthalocyanines which displays many different substituents such as long hydrocarbons around its skeleton and contains a various metal inside of the phthalocyanine.

Obesity is growing problem in Korea. We had a case of bariatric surgery during gastric cancer operation. Patient was 29 year old Korean lady with early gastric cancer located in the lesser curvature side of the middle 1/3 of the stomach. Her body weight was 89 kg, height 163 cm, and thus body mass index was 33.5 kg/m2. Preoperative blood pressure was 130/90 mmHg, hemoglobin 12.9 g/dL, total lymphocyte count 3,280/mL, serum albumin 4.3 g/dL, CEA 1.1 ng/mL, CA 19-9 9.1 ng/mL, and alpha fetoprotein 2 ng/mL. Another associated disease was right thyroid follicular neoplasm. The chest X-ray was normal. After IM injection of 2,500 units of heparin 30 minutes before the induction of general anesthesia, she received curative subtotal gastrectomy and Roux en Y gastrojejunostomy when a malabsorption loop of 120 cm jejunum was incorporated between the Treitz ligament and the end to side jejuno-jejunostmy site at May 29th 2006. Her postoperative course was uneventful except a minor wound seroma and the elevations of serum amylase(up to 4 folds) and lipase(up to 2 folds). She lost her body weight 9 kg in 5th, 21 kg in 7th, and 27 kg in 10th postoperative months to became 61.5 kg. On follow up exams in July 2008, she gained 4 kg to overcome her weakness and fatigue. From the above result, the incorporation of a malabsorption loop during reconstruction phase of gastric cancer operation was a good option for obese gastric cancer patients especially in cases of early gastric cancer.

The pH changes in 4 small cavities prepared at the facial inner dentin and lingual outer dentin of the cervical and apical portion of root filled with calcium hydroxide pastes were investigated. Forty extracted permanent teeth with single canal were instrumented with step-back method, and then 4 small cavities were prepared. Two inner dentin cavities were cut a distance of about 1.0㎜from the canal wall and two outer dentin cavities were cut to a depth of about 0.5㎜ from the root surface. Root canals and prepared cavities were flushed with 17% EDTA, and then irrigated with 5% NaOCI to remove smear layer. Teeth were randomly divided into four groups. Control group was not filled and the remaining other groups were filled with mixture of calcium hydroxide and distilled water, Vitapex(r) paste and Pulpdent(r) paste respectively. The pH change of the dentin in each cavity was measured at 0, 1, 3, 7, 14, 21, 28, 60, 90 days with pH microelectrode(WPI Co., USA). The results were as follows : 1. The groups obturated with Pulpdent(r) paste and Aqueous calcium hydroxide produced the increased pH level at 1 day and maintained plateau over next 3weeks and decreased after 3weeks. 2. The group obturated with Vitapex(r) paste observed no significant pH change until 2weeks and slight increased pH at 3weeks and sequential increasing after 3 weeks. But, the pH in the group obturated with Vitapex(r) paste remained significantly below the pH measured in the other two experimental groups(P<0.05). 3. All experimental groups showed pH level similar to control group after 28 days. 4. The pH of outer dentin is slightly higher than that of inner dentin. There is no significant difference in pH level between apical and cervical dentin throughout the duration of the experiment, though apical dentin showed slightly higher pH than cervical dentin at 1 day(P<0.05).

쑥 분말 사료를 암돼지 및 거세돈에 첨가하여 그 수준에 따라 0%(T1, 암돼지, T2; 거세돈)와 1.5%(T3; 암돼지, T4, 거세돈)로 각 구별 45두씩 배치, 42일간 급여하여 생산된 돈육의 육질특성은 다음과 같다. 도체중량과 등지방두께는 73가 가장 낮았으며, 도체등급에서는 처리구간 유의차가 없었다(P>0.05). 쑥 분말 급여시 암돼지간(T1과 T3)에서는 조회분, 거세돈간(T2와 T4)에는 조지방 및 조회분 함량이 유의적으로 증가하였다(P<0.05). pH는 저장기간에 증가함에 따라 모든 처리구에서 감소하였으며, 쑥 분말 급여 처리구(T3와 T4)에서다소 높은 pH값을 나타내었다 드립감량은 처리구간에 일정한㎏/㎠경향을 나타내지 않았지만 저장기간이 경과함에 따라 높아졌다. 전단가(shear force, ㎏/㎠)는 T1을 제외한 모든 처리구에서 저장기간이 길어짐에 따라 감소하였다. 명도와 적색도는T3가 T1 보다 다소 높은 수치를 보였으나, 거세돈간(T2와 T4)에서는 오히려 낫게 나타났다. 저장기간이 증가함에 따라 TBARS와 VBN값은 공히 유의적으로 증가하였으며(P<0.05),쑥 분말 급여 처리구(T3 및 T4)에서 유의적으로 더 높게 나타났다(P<0.05). 지방산 분석결과, 포화지방산(saturated fatty acids)은 대조구에 비해 쑥 분말 첨가수준 증가에 따라 포화지방산은 높아지고 상대적으로 불포화지방산(unsaturated fatty acids)은 낮아지는 경향이 있었으나 유의차는 없고, 콜레스테롤의 경우에도 동일하게 유의적인 차이가 없었다. 전체적인 기호도는 신선육 및 조리육 공히 처리구가 낮은 점수를 얻었다. 향후 쑥 분말 급여에 대한 보다 많은 연구가 진행되어야 할 것으로 판단된다. This study was carried out to investigate the feeding effects of mugwort powder on meat quality characteristics for 42 days. The results obtained were as follows; Carcass weight(㎏) and backfat thickness(㎜) of T3 showed the lowest compared with other treatments. Grade scores were not significantly differ among the all treatments. In the proximate composition, crude ash content was higher(P<0.05) in the T3 than that of T1, while, crude fat and crude ash contents in T4 were higher(P<0.05) than those of T2. pH values were tended to low as storage period extended, in particular, those values slightly higher in the T3 and T4. Drip loss(%) was tended to increase during storage. Shear force(㎏/㎠) in all samples showed the decreased during the storage, except for Ti. L^(*) and a^(*) of T3 were slightly higher than those of T1, while, T4 was lower than T3. TBARS and VBN of all samples were significantly increased(P<0.05) as storage period extended, those values significantly higher(P<0.05) in the T3 and T4. There were no differences in saturated fatty acids, unsaturated fatty acids and cholesterol of pork meat between control(T1 and T2) and treatments(T3 and T4). The sensory score of pork samples fed with mugwort power were lower than that of control(T1 and T2) in both fresh and cooked meat. Further studied are needs on the pigs fed with mugwort powder.
