On the basis of the study intended to research by crosssectional study keeps pace with semilongitudinal study the growthaccelerating phenomena that Maximum Growth age in teenager's body-height. By the random sampling method, the subject of study are 12659 persons(male;6355, female;6304) that they are from 7 ages to 17 ages in the whole country including the rural community. The measurement period passed three month days, the statistical data became electronic data processing system with computer.The other side, body-height and MGA of Koreans who had been for during the period from 1925 to 1966 proved transition of the growth-accelerating phenomena by research data reported between 1913 and 1983. The results are as follows; 1. The Growth and Development-Value of Body-height. An age bracket the growth and development-value of body-height were, respectively, male is 123.88+/-5.05cm and female is 123.29+/-5.54cm for 7 ages group. these indices increased with age. The top-value reach, respectively. 169.08+/-5.62cm and 157.57+/-6.13cm. The intersecting ages of male and female were the age 8.5~12.5, during these periods, female excelled male but after these periods, male excelled female again. In case of body-height, MGA's are 7.0cm for male between 12 and 13 age, and 7.01cm for female between 8 and 9 ages. As a rule, body-height of male excelled female but intersection phenomena of male and female appeared between 8.5 and 12.5 ages. By reginal groups, it is most prevailing is Seoul, and medium size cities and rural community come in order. By regional groups, intersection phenomena of male and female are. a region of Seoul; 8.5~11.5 ages, a region of Daejeon; 7.5~9.5 ages, rural community; 11.5~14.5 ages the whole country's average; 8.5~12.5 ages By regional groups, the rate of maximum increase in a year are a regional of Seoul; male is 7.23cm as 13 ages, female is 7.65cm as 9 ages. a region of Daejeon; male is 7.85cm as 11 ages, female is 8.39cm as 9 ages. rural community; male is 7.65cm as 14 ages, female is 6.25 as 12 ages. the whole country's average; male is 7.0cm as 13 ages, female is 7.01 as 9 ages. 2. Maximum Growth Age (M.G.A.) By reginal groups, maximum Growth Age's are as below in a region of Seoul, MGA's are 12.63 for male and 9.01 for female, which shows that MGA for female appears about 3.5 years earlier than that for male. In a retion of Daejeon, MGA's are 9.20 for male and 8.93 for female, which show that they are all much the same in M.G.A. In rural community, MGA's are 14.00 for male and 11.89 for female, which shows that MGA for female appears about 2 years earlier than that for male. In the whole average, MGA's are 13.01 for male and 8.97 for female, which shows that for female appears about 4 years earlier than that for male. For boy, M.G.A. shows fastest-growing in Daegjeon, and Seoul and rural community come in order. For girl, It shows equal growth in Seoul and Daejeon, rural community comes later. 3. The M.G.A's in body height of male are respectively the age 15.02 in 1913, 14.23 in 1956, 13.86 in 1967, 13.62 in 1975, and 12.82 in 1981, while those of female are the age 12.0 in 1940, 11.52 in 1965, 9.53 in 1975, ad 11.16 in 1980; these data show that the MGA of the Koreans has been getting younger. 4. The equation of linear regression of all the MGA's in body height are as follow; Male: Y(M.G.A) = -0.020 x (the year) + 15.19 : female: Y(MGA) = -0.028 x (the year) + 13.2549. 5. The corelation of all the MGA's in body height are as below; male;r=-0.329, female;r=-0.252. 6. From the transition of the growth-accelating phenomena in 1980 we can capture the fact that the MGA's has been getting younger by 0.2 year per 10 years. 7. The MGA's in bodyheight are shown in table 4. 8. The future growth-accelating phenomena in body height are expected to show the similar tondency like that of the past, in 1910's but it should by more precisely reviewed after investigating the phenomena of the years directly ahead.

The purpose of this study was to find the characteristics of lateral cephalogram of skeletal class III malocclusion patients to whom orthognathic surgery was essential. For this study 37 patients with skeletal class III and going to treat or be treated orthognathic surgery(age 7 - 17) were selected to experimental group and 56 people with normal occlusion ( age 8 - 13) were selected to normal group and the two groups were evaluated and statistically analyzed and the results were as follows. 1. In comparison of experimental group and normal group in prepubertal group, there were significant differences in ANS-Ul/Me-Li, Mx. Length/Mn.Length, S-N/Go-Me, Wits, ANB, SN-Pog, IMPA, Facial Convexity, APDI (P<0.05) 2. In comparison of experimental group and normal group in pubertal group, there were significant differences in ANS-Ul/Me-LI, S-GoN-Me, Mx.LengtWMn.Length, S-N/Go-Me, Wits, Saddle Angle, SNB, ANB, SN-Pog, R MA, Interincisal Angle, Facial Convexity, APDI (P<0.05) 3. Among items showing characteristics of skeletal class M malocclusion, there were no significant differences between prepubertal group and pubertal group in other items except Mx. LengtblMn. Length, APDI (P<0.05) 4. The significant correlationship was the highest between Saddle Angle and SNB, SN-Pog and SNB, ANB and Facial Convexity in experimental group.

Benzene and toluene, which are widely used aromatic hydrocarbons in workplace, are recently proved to cause health hazards due to their toxic effects. This study investigated the influence of toluene on the urinary excretion of benzene metabolite by administering short term exposure limit(STEL) of these compounds(i.e., 13.8mg/kg of benzene and 108.8mg/kg of toluene) intraperitoneally into Sprague-Dawley rats. After administration, urinary phenol concentration of rat was measured by gas chromatography for every three hours. Data were analyzed by non-parametric statistical methods using Kruskal-Wallis multi-sample test and Mann-Whitney U test. The following results were obtained: 1. Administration of STFL-benzene increased urinary phenol concentration in rats. 2. Urinary phenol concentration was increased logarithmically according to the dosage of benzene. 3. Excretion of phenol in urine was decreased when benzene and toluene were administered simultaneously compared with administering benzene alone. In Summary, these results reveal that administration of STEL of toluene has antagonistic effect of urinary excretion of benzene metabolite in rats.

We report a case of classic Kaposis sarcoma(KS) in a 74-year-old man who had asymptomatic red-dish-blue or dark-brown macules, papules and nodules on his bo hower extrimities. The biopsy specimen showed typical histopathologic features of FS including a highly vascularized lesion with a proliferation of spindle-shaped cells accompanied by etravasated erythrocytes and variable number of inflammatery cells. Many of the spindle-shaped cells associated with the proliferating vessels in KS lesion expressed factor VIII-related antigen. He was treated with 1500 cGy of radiation(300 cGy per day for 5 successive day. Four weeks after radiotherpy, gross and histopathologic findings were mucl improved and healed leaving hyperpigmentation.
