朴吉淳,宋大鎭 제주대학교 1974 논문집 Vol.6 No.-

In this survey we tried to find out how habit, income, and the price of foodstuffs affected the eating habits of the people in Je Ju Do so that the most economical and efficient plan of foodstuffs distribution could be carried out. The results are as follows : 1) The rate of consumption of several foodstuffs (banana, dried persimon, canned fish, canned meat etc. ) decreased markedly when their price doubled. But the rate of consumption of other foodstuffs (soy sauce, bean paste, hot bean paste etc. ) only decreased slightly when their price doubled. 2) when we asked what foodstuffs the people would eat if their food budget was increased 50%, the highest percentage responded that they would eat more rice cakes. Others mentioned rice, barley, wheat flaur, broad, apple, mandarin oranges, pears, eggs, milk, etc. But the increase of these foodstuffs was only slight. The consumption of wine was reduced. 3) The frequency of consumption for some foodstuffs was small while for others it was large.

서정길,김찬희,배윤정,문호성,김근용,박희연,윤호동,김창훈,변대석,홍용기,박남규 한국어병학회 2003 한국어병학회지 Vol.16 No.3

Mastoparan B (MPB)는 벌독으로부터 정제된 양친매성α-helical 구조를 취하면서 14개의 아미노산 잔기로 구성된 염기성 항균성 펩타이드로서 여러 가지 생물막과 작용한다. 본 연구에서는 우리 나라 연안의 적조 (HABs, harmful algal blooms)를 일으키는 4종의 적조생물 (Alexandrium tamarense, Chattonella catenatum)에 대한 MPB의 살조효과를 조사하였다. MPB의 4종의 적조생물에 대한 살조효과는 31.3㎍/㎖에서 세포의 lysis또는 ecdysis와 같은 형태로 현미경으로 관찰할 수 있었다. 또한 MPB는 C. marina 및 C. polykridorides에 대해서 A. tamarense와 G. catenatum보다 더욱 강한 살조효과를 나타내었다. 이러한 MPB의 HABs에 대한 살조효과연구는 새로운 살조물질을 개발하기 위한 자료가 될 것으로 생각된다. Mastoparan B (MPB), an antimicrobial cationic peptide isolated from the venom of the hornet Vespa basalis, is a basic amphipathic a-helical peptide composed of fourteen amino acid residues. In this study, we have investigated the algicidal effect of MPB against hatmful algae blooms (HABs) casative Alexandrium tamarense, Chattonella marina, Cochlodinium polykrikoides and Gymnodinium catenatum. The algicidal effect of MPB showed in the concentration of 31.3 ㎍/㎖ to 500 ㎍/㎖ against 4 HAB species and observed cell lysis or cell ecdysis by microscopy. MPB reacted more sensitive to C. marina and C.polykrikoides than A. tamarense and G. catenatum. The algicidal study of MPB against HABs will provides much insight into development of new algicidal substances.

The experiment was conducted to study the effect of different energy level on weight gain, feed intake, the efficiency of feed, energy and protein with 200 birds of Abor Acre male broiler chicks for 8 weeks. In order to decrease the energy level, the basal diet was replaced by soybean meal-rice hull mixture by the ratio of 5%, 10%, 15% and 20%. The results obtained were as follows. 1. The weekly body weight gain was reduced from 182.5gm. for control diet(3200 Kcal) to 170.8gm. for Diet B (2780 Kcal) in starter period and from 375.5gm. for control to 345.2gm. for Diet C (2620 Kcal) in finisher period. 2. The weekly feed intake for control, Diet C, A, D and B in starter period were 315, 311, 307, 298 and 275gm. in order and the intake for Diet C, B, A, D and control in finisher period were 1029, 1024, 983, 943 and 890gm., respectively. 3. The feed conversion ratio had a increasing tendency for the diet including higher ratio of soybean meal-rice hull mixture. 4. As the energy level of diet decreased, the energy efficiency ratio tended to increase in starter period and had no regular tendency in finisher period. 5. The decreased energy level of diets had a tendency to decrease the protein efficiency ratio except for Diet A in starter period and in finisher period concurrently.

Objective : Between 1991 and 1993 data were collected to evaluate risk factors for endometriosis. Design : A case-control study was conducted on 54 cases with laparotomically confirmed pelvic endometriosis consecutively admitted to CNUH. The control group consisted of 60 women admitted to hospital for benigh gynecologic disease. Results : No relation emerged with marital status, age at marriage, marital life, level of education, socio-economic status, age at menarche, menstrual regularity, number of spontaneous abortion, duration after last delivery, height and weight. But compared to control group, longer menstrual period, larger menstrual amount, severe menstrual pain, less number of parity, and less number of induced abortion signifcantly increased risk of endometriosis Conclusions : This study showed that frequent menstrual cycles and long period of menstruation with frequent and large amount of retrograde menstrual flow increased the risk of endometriosis.

화학적으로 활성화된 GroupⅢ와 GroupⅣ구심성 근신경의 Gamma Motoneuron에 대한 반사효과

방대홍,홍승길,남숙현 고려대학교 의과대학 1983 고려대 의대 잡지 Vol.20 No.3

In decerebrated cats the effects of fine muscle afferents (groups Ⅲ and Ⅳ) upon gamma motoneurons were studied. The efferent activity was exracellularly recorded from small filaments of ventral roots or from filaments of musole nerves. Fine muscle afferents were selectively activated by bradykinin, potassium and serotonin. For comparison, succinylcholine was administrated to activated muscle spindle afferents. Forty gastrocnemius-soleus gamma motoneurons were recorded. Thirty-six (90%) of them had a tonic background discharge in the absence of intentional stimulation. A high susceptibility to an increased activity in fine muscle efferents was found for the gamma motoneurons. Practically all neurons both to homonymous extensor and antagonistic flexor muscles responded with an excitation to at least one of the algesic substances applied. Only two out of fifteen gamma motoneurons responded to succinylcholine. Thus indicationg a weak convergence from muscle spindle afferents. Control experiments demonstrated that the responses to bradykinin and potassium are entirely due to the nervorus outflow from the gastrocnemius-soleus muscle. In contrast, serotonin influencing the gamma motoneurons has unknown additional sites of action. The results indicate that muscular group Ⅲ and/or group Ⅳ units activated by algesic substances evoke excitatory effects upon gamma motoneurons.
