An epidemiological study is to observe and analyse 100 cases of lung cancer in Korean, which had been diagnosed actually at the general hospitals in Korea from 1970 through 1974, to discover the tendency of the lung cancer by sex, age, occupation, duration of clinical symptoms before diagnosis, site of cancer in lung, size of cancer, occurrence, treatment, prognosis, smoking and pathological findings as follows. 1. Males were affected 5.7 times more than females, the peak incidence of lung cancer were 50 years old age group. 2. The occupations of the cases were commerce, agriculture, industry, laborers and teachers, etc. in thht order. 3. The average duration symptoms from onset to diagnosis were 5.5 months. 4. The cancers were affected more right side than left side of the lungs, Particularly the most of them were affected in the upper lobes of the lungs. 5. The average diameter of the tumors was 5.5crX6.5cm, However the largest of them was 10cm X 13cm. 6. The most cases of the lung cancers were occurred primarily. 7. Out of the 100 cases, 58 cases had no treatment, 23 cases had palliative-symptomatic treatment, of cases by special chemo-therapy, 7 cases by surgery, and 5 cases by cobalt 60 or X-gay. 8. In the view point of prognosis, the most cases of the lung cancers died within one year atfer diagnosis. 9. The smoking was one of the causative factor of lung cancer, but there was no significant diferentiation by means of the amount of smoking. 10. The most cases of the lung cancers diangosed histo-pathologically, were epidermoid(squamous) type.

The detection of the tubercle bacilli is absolutely necessary to make definite diagnosis of patients with genitourinary tuberculosis. Recently it has been reported that the detection rate of tubercle bacilli from the patient's urine is decreasing because of abuse of the anti-tuberculous drugs and the resistance developed in the experimental animals such as mouse and guinea pig (Marks, 1972). Therefore the necessity of the development of better diagnostic methods has been mandatory. Recently it was reported that the Korean chipmunks(Tamias sibiricus asiaticus. Gmelin) are highly susceptible to tubercle bacilli (Chang et al., 1971). The specific objection of this study is to pursue the possibility of using the chipmunks for the early diagnosis of genitourinary tuberculosis. Twenty-four hour urines of 34 patients with suspected genitourinary tuberculosis were tested for tubercle bacilli with smear, culture, and inoculation ink chipmunks and mice intraperitoneally. The results are briefly summarized as follows: 1. 18 cases out of 34 patients with suspected genitourinary tuberculosis were confirmed to be positive by any means of stained smear, culture and animal inoculation. Of 18 proved genitourinary tuberculosis. 12 cases were confirmed by smear, culture and mouse inoculation, and on the other hand. 14 cases by chipmunks inoculation. 2. In the group of chipmunks inoculation, 8 cases were found to be positive on the 10th day and 14 cages on the 20th day. 3. These findings suggest that the period required for the detection of tubercle bacilli was shorter and the positive rate was higher than that of other animals and other methods. For the clinical applications of the Korean chipmunks as a diagnostic tools, further effort is considered to be necessary.

This is a report of attempts to compare the growth yields of various species of fastidious mycobacterium inch1ding human pathogens and non-pathogens in the conventional Dubos liquid medium and two simple media formulated recently; one is a medium containing 0.1% hyaluronic acid and 6.0% bovine serum albumin and the other is a semisyntheic medium made of umbilical cord extract supplemented with 10% sheep serum as a final concentration. All mycobacterial strains employed in experiments gave the heaviest growth yields in the hyaluronic acid-bovine serum albumin medium (HAS medium), among the three media. Dubos liquid medium seemed to be inferior to a medium made of umbilical cord extract (UCE medium) in supporting mycobacterial growth. There were three-to seven-fold increases in dry weight of the bacteria grown in the HAS medium as compared with those in the Dubos liquid medium. We also looked for the possible effect of bovine serum albumin (BSA)in the HAS medium on mycobacterial growth. As a result, we found that the amount of BSA in the HAS medium, ranging from zero to 6.0% in the medium, showed no substantial effect on the mycobacteria1 growth.

A retrospective study has been made of 170,026 cases of motor vehicle accidents which had been reported to the National Police Headquarters of Republic of Korea, 1983. Also a study has been made of 264 cases of road traffic casualties who were treated at the Eul-ji General Hospital from Jan. 1, 1983 to Dec. 31, 1983. This study was conducted to find out the nature and pattern of the traffic accidents from the clinical and epidemiological view points. In additions, the modes of injury from the road accidents were pursued which might help to reduce the traffic accident rate. The results of the study were summarized as follows; 1. In this study, the highest incidence was in the age group between 21-30 years (21.29%). And the age group of highest death rate was under 10 years (7.28%). 2. In the comparison of sexual differences, male was dominated in accidents number and death rate. (Casualty rate; 61.66%). 3. In the comparison of each hour differences, the accident was mostly occurred during afternoon from 16 : 00 to 18 : 00 (12.23%). 4. The most common day of week was Sunday (14.74%). 5. The most common season of year was Autumn (27.92%). 6. In the comparison of occupational differences, the high incidences were showed in labor men (31.06%) and business men (12.12%). 7. In the comparison of accidental vehicles, the most common vehicle were cars and the next were trucks and buses. 8. The most common mechanism of accidents was collision (57.41%). 9. In the comparison of clinical differences, orthopaedic and neurosurgical injuries were most common types of the hospitalized casualties. 10. In the comparison of anatomical fracture sites, the most common site was tibia (15.81%) and the next site was femur (12.56%).

We report a mild variant of hypomelia-hypotrichosis-facial hemangioma syndrome in a 3 month-old female. The patient showed major features of the previously reported cases including flexion deformities of both upper extremities, sparse light colored hair, mid-facial hemangioma and a characteristic facial appearance. Roentgenogram showed radio-humeral synostosis at both elbow joints by which shortening of upper limbs could be anticipated. However, intra- and extrauterine growth retardation were not remarkable and the lower limbs were not affected.

Attention has been paid to the thiocarbanilide derivative and the authors synthesized some new compounds of thiocarbanilides for experimental studies on tuberculosis and leprosy. The series of newly synthesized chemical compounds of thiocarbanilides were studied for comparision with the already known antimycobacterial agents; INH, PAS, Streptomycin and D. D. S. The strains of Mycobacterium tubercubsis (H37 Rv, Ravenel, and B. C. G.) and Mycobacterium phlei were used for the in vitro experiments. In the in vivo experiments, the strain of Mycobacterium tuberculosis var. bovis (Ravenel) was employed. The strain of Mycobacterium leprae murium (Hawaiian strain) was used for the murine leprosy experiments. The experimental animals for the in vivo tests were white mice (CFW strain) and these were extensively employed in tuberculosis and leprosy as well. Sixteen cases of Various types of human leprosy, were treated with one of the newly synthesized thiocarbanilides (L-4). Among the newly synthesized chemical compounds of thiocarbanilides studied for their antituberculous and antimurine leprosy activity in vitro and in vivo experiments, two compounds were shown to be suppressive agents for those infections without significant toxicity. These two compounds were named tentatively as L-1 and L-4. 1) LD50 of L-1 was 1,054 mg/kg and that of L-4 was 1,028 mg/kg, while the LD50 of INH was 650 mg/kg and PAS was 4,000mg/kg orally in the experimental animals. 2) L-1 and L-4 showed remarkable suppressive activity in vitro using solid media with 100r/ml. concentration. These data were parallel to 1r/ml. of INH and 50r/ml. of PAS. The inferiority of L-1 and L-4 to INH and PAS in vitro studies might have been due to the water insolubility of these compounds while INH and PAS were readily soluble in water. 3) In vivo experiments with L-1 showed a much-more superior antituberculous effect than was found with INH and PAS. 4) A method of grading the bacterial count in a homogenized tissue suspension of visceral organs (lungs, liver, spleen and kidneys) using the simple technique of the Gaffky scale was accurate and time saving technique in screening the results of the chemotherapeutic agents in tuberculosis. 5) Among the newly synthesized compounds L-4 showed the most remarkable suppressive effect on murine leprosy. The suppressive results were similar to those of INH. 6) The method of measuring the size and the weight of leproma at the inoculated site was simple and is an adequate screening test for chemotherapeutic effect in murine leprosy. 7) In the trials with human leprosy 16 cases of various types, using L-4, the effectiveness in clinical as well as in bacteriological improvement was remarkable. a) After L-4 treatment decrease in bactriologica1 indices and remarkable clinical improvement after a relative1y short period of treatment were observed. b) L-4, up to the maximum daily dose of 500 mg, can be safely administered orally to the patients without any significant side reactions. c) L-4 could be used with remarkable clinical improvement for the patients in lepra reactions.
