This is a study on the changes of the ancient underclothes. Underclothing includes all such articles, worn by either sex, as were completely or mainly concealed from the spectator by the external costume. Functions of underclothes are follow ; to protect the body from cold, to support the shape of the costume, to cleanliness, to erotic use of underclothes and as a method of class distinction. Linen is the oldest as materials and cotton came into general use after the Restoration of 1660. We must suppose that woolen petticoat was at least as old as the Middle Ages and silk was rarely used until late in Victorian times. Until the middle of the last century underclothes were necessarily hand-made, and the absence of fit was noticeable until the introduction of man\`s drawers, fitting the leg, at the close of the eighteen century. Strings and ribbons were the fastenings for underclothes until the middle of the seventeenth century, when they were replaced by buttons. One outstanding example of the first type of figures is a Babylonian girl of about 3000 BC from Sumeria who wears that today would immediately be described as briefs. Female statues show no trace of anything being worn under the chiton, but there is literary evidenced that the Greeks. A band of linen of kid was bound round the waist and lower torso to shape and control it. It was known as the Zone or girdle. The apodesmos, meaning a band, breast band, occurs in a fragment of Aristophanes. A Roman mosaic shows female athletes wearing a bikini-briefs and bra in the fourth century AD. A similar band, called the mastodeton, or breast band, was also worn round the bust, apparently to flatten or minimise it, as in the 1920s, and not, to stress its curves. In Rome, too, women sometimes wore bands of material round the hips and bust-a cestus or girdle is referred to by the poet Martial and seems to have been similar to the zone, but wider, and the strophium, or breast band, is mentioned by Cicero.

Physiological effects in SAM P6 and Rl by administration of Cervus cornu, Astragali Radix, Rehmanniae Radix, and Angelicae Radix extracts were screened to know in vivo activities of each extracts. We measured complete blood cells (CBC) such as aBC, HGB, and HCT using coulter's method. Plasma concentrations of albumin, glucose, alkaline phosphatase, calcium, creatinine, inorganic phosphate, urea and total iron ere also analyzed using biochemical clinical autoanalyzer. Plasma concentrations of cortisol, total T$_3$, and total T$_4$ were measured by chemiluminescent immunoassay methods. At 12 weeks after birth, Cervus conu or Astragali Radix or Rehmanniae Radix extracts were given 5 g/Kg.day p.o. for 0,7,14,21, and 30 days each in both SAM Rl and SAM P6. Angelicae Radix study was done the same as the others except the mice were 16 weeks after birth. The RBC, HGB, and HCT levels after administration of Astragali and Rehmanniae were elevated in SAM Rl, but those in Cervi study were increased in SAM P6 the most. Decreases in alkaline phosphatase concentration of SAM Rl and P6 after Cervi administration were detected. Total plasma iron concentration was decreased by Angelicae administration in SAM P6. In general, Angelicae and Rehmanniae stimulate increases in cortisol, but total T$_3$ and T$_4$ levels were also elevated by all these extracts. In conclusion, these herval medicine extracts help hematopoiesis in SAMs through probably different mechanisms.

The phenotypes of hemoglobin, albumin and transferrin of 3U2 Jindo dogs in Jindo area were studied by starch gel electrophoresis for hemoglobin and albumin, and by polyacrylamide gradient gel electrophoresis for transferrin. The results obtained were as follows: 1. In the hemoglobin phenotypes, three phenotypes, HbAA, HbAB and HbBB, which were controlled by two allelic genes, $Hb^A$ and $Hb^B$, were observed and their frequencies of appearance were 1.65%, 10.60% and 87.75% respectively. The distribution of gene frequency was calculated as 0.0695 in $Hb^A$ and 0.9305 in $Hb^B$. 2. In the albumin phenotypes, three phenotypes, Alb FF, Alb FS and Alb SS, which were controlled by two allelic genes, $AIb^F$ and $AIb^S$ were observed and their frequencies of appearance were 12.59%, 25.56% and 61.85% respectively. The distribution of gene frequency was calculated as 0.2537 in $AIb^F$ and 0.7463 in $AIb^S$. 3. Analysis of transferrin phenotypes showed 6 different types which were controlled by three allelic genes, $Tf^B$, $Tf^C$ and $Tf^D$ and their frequencies of appearance were 54.04% in TfBB, 17.54% in TfBC, 9.82% in TfBD, 8.07% in TfCC, 7.37% in TfCD and 3.16% in TfDD. The distribution of gene frequency was calculated as 0.6772 in $Tf^B$, 0.2053 in $Tf^C$ and 0.1175 in $Tf^D$.

박스 구조들은 상.하수도관, 통신 및 전기선로, 도로, 철도 등을 위한 여러가지 목적으로 오래 전부터 많이 사용되어 왔다. 도심지에서는 대부분 지반을 굴착하여 박스 구조물을 설치한 후에 되채움하는 과정을 거친다. 그러나 박스에 작용하는 토압을 위한 기존의 설계법에서는 굴착(또는 되채움)되는 단면의 형상을 고려하지 못하고 있다. 본 연구에서는 매설박스 설계시 굴착되는 단면형상을 고려할 수 있는 새로운 토압이론식을 제안하였다. 이 이론식에 의한 수평토압은 유한요소해석 결과와 비교적 좋은 일치를 보여 주었으나, 기존설계법에 의한 토압은 상당히 과대평가되었다. 박스의 상단면에 작용하는 연직응력의 이론값은 기존 설계법 및 유한요소해석 결과와 거의 유사하였다. 그러나 박스의 바닥면에 작용하는 반발응력은 기초지반의 탄성계수에 따라 크게 좌우되므로, 새로운 이론식은 기초지반이 느슨한 모래인 경우를 제외하면 직접 적용이 어려웠다. 한편, 유한요소해석에 의하면 박스에 작용하는 수평토압은 굴착면의 경사와 굴착저면의 폭에 따라 크게 좌우되었다.

Objectives : The purpose of the study is to examine the apoptotic effects of Pseudomonas aeruginosa exotoxin A(PEA) in squamous cell carcinoma(SCC) 25 cells. Methods : Cell growth reduction and apoptosis induced by PEA were confirmed by WST-1 assay, Hoechst 33258 staining, flow cytometry analysis, and Western blot assay. Results : The PEA treatment decreased the cell viability in a dose and time dependent manner: control; $100{\pm}0^e$(p<0.01), 0.1875 nM; $87{\pm}4.36^d$(p<0.01), 0.375 nM; $82{\pm}0.58^d$(p<0.01), 0.75 nM; $72{\pm}1.67^c$(p<0.01), 1.5 nM; $51{\pm}1.53^{bc}$(p<0.01), 7.5 nM; $31{\pm}1.20^{ab}$(p<0.01), 15 nM; $26{\pm}0.67^a$(p<0.01), control; $100{\pm}0^a$(p<0.05), 24 h; $51{\pm}1.53^b$(p<0.05), 48 h; $16{\pm}0.5^c$(p<0.05), 72 h; $12{\pm}1.67^d$%(p<0.05). The PEA was observed on SCC 25 cells with the half maximal inhibitory concentration(IC50) value of 1.5 nM at 24 hours. The PEA treated SCC 25 cells demonstrated several types of apoptotic indications, such as nuclear condensation, the increase of sub G1, and the cleavage of PARP-1 and DFF 45. Conclusions : PEA showed anti-cancer activity against SCC 25 cells via apoptosis. PEA may potentially contribute to human oral cancer treatment.

In spite of many projections of TMJ, there are rarely satisfactory projections of TMJ. The author traced and measured the P-A cephalograms, which number is 70 in each male and female, them finding the following results. 1. The long axis of the condyle is 19.80㎜ on the right, and 19.89㎜ on the left in male, and that of 18.65㎜ on the right and 18.10㎜ on the left in female. 2. The intercondylar distance is 119.02㎜ in male, and 108.20㎜ in female, resulting that the intercondylar distance in male is much longer than that in female. 3. The right and left deviation of the midline passing through the center of the intercondylar distance and prosthion is +0.37㎜ in male, +0.64㎜ in female, and its range is from -4.6 to +5.7㎜ in male, and from -3.2 to +6.1㎜ in female, resulting that prosthion nearly coincides with midline. 4. The angle of the intercondylar distance and the long axis (vertical angle) is +5.48' in male, and +6.02' in female, resulting that there is a little difference between male and female and the angle of the right is greater than that of the left in both male and female. 5. The typology of the condyle in sum of male and female is; Right: A type 55 (39.3%), B type 66 (47.1%), C type, 12 (8.6%), D type, 7 (5.0%), E type, 0 (0%) Left: A type, 60 (42.9%), B type, 58 (41.4%), C type, 14 (10.0%), D type, 8 (5.7%), E type, 0 (0%) 6. The distribution of the typology between the right and the left is; AA 26 (18.6%), AB 50 (35.7%), AC 10 (7.1%), AD 3 (2.1%) BB 26 (18.6%), BC 13 (9.3%), BD 9 (6.4%), CC 0 (0%), CD 3 (2.1%)
