Based on a study of 140 caaes of spondyloses with chronic backache, the sites and types of spurs and underlying congenital anomalies were analized. The following results were obtained. The most common sites of spurs were expected to be between L5 & S1 but contrary to the expectation, these were found most commonly between L4 & L5 and between L3 & L4. The reason for the preponderance of the spurs between L4 & L5 and L3 & L4 were not immediately available. All spurs represent claw type except in 4 cases which resemble traction spurs of McNab but without segamental instability. There were 39 cases of congenital anomalies. 28 of them were of tropism. Thus we conclude that the most common congenital anomaly associated with spondylosis is tropism.

Familial Renign Chronic Femphigus(FRCP) is rare, persistent and vesicobullous genodermatoai. Three casee of FRCP with typical clinical and histapathological findings are reported. The first case of FBCP was 27-year-oId man who had recurrent episodes of grou vesicles and rust with miId pruritue at the posterior neck, in both axillae and in inguinal area for 10 years. The second case was 49-year-old woman with skin lesions of recurrent persistent. vesicles, pustules on the erythematous skin, crust and lichenification on the flexural area of extrimeties, axillae, ingumal and neck area for 10 yeara. The third case was 49-year-old male patient who had recurrent pruritic grouped vesicles with crust on the neck and axillary area. In all three patients, skin eruptions usually began and or aggravated in the spring or summer and tend to heal spontaneously in the autumn and winter and showed positive Nikolsky sign. The only one case of the reported three casea had familiaI history of skin lesions similar to FRCP. Histopat,holag;ic finding of biopsy specimens from the vesicular eruption showed auprabasal vesiculation with acantholysis, lacunae and villi formation in all 3 cases.

Programmed cell death (PCD), or apoptosis, plays an important role in embryonic development, metamorphsis, hormone-dependent atrophy and tumor growth, as a physiological event regulating the cell number or eliminating damaged cells. Currently hybridoma cell production, resulting from the fusion of myeloma cells with antibody producing spleen cells, is widely used in various fields of life science. This technique requires a hypoxanthine guanine phosphoribosyl transferase (HGPRT) deficient mutant myeloma cell line as a fusion partner. When these rnutant cells are treated with aminopterin plus hypoxanthine-thymidine (HAT) after the cell fusion they are selectively and efficiently eliminated so that one could get only fused hybridoma cells. But there hasn't been any report regarding this selective elimination mechanism of HGPRT mutant myeloma cell. By using HGPRT myeloma V653 as a model system this study demonstrated that PCD was induced by aminopterin treatment of this V653 cell. And this PCD was further characterized by cotreatement of cycloheximide, actinomycin-D, and calcium ionophore A23187 together with aminopterin. The apoptotic endonuclease involved in this PCD process was also detected and characterized. When V653 cells were incubated for the various periods of time in the presence of 0.4 uM aminopterin, the viability was continued to decrease until 48 hours of aminopterin treatment and there was no viable cell affer 36 hours of incubation. DNA fragmentation was detectable 3 hours of incubation and peaked between 12 and 18 hours of aminopterin treatment. The induction of cell death and DNA fragmentation of V653 cells by aminopterin were inhibited by protein synthesis inhibitor, cycloheximide, and RNA synthesis inhibitor, actinomycin-D and maximal inhibitory effects on cell death were seen at concentrations of 2 ug/ml and 0.5 uM, respectively. Ca2+ ionophore A23187 promoted aminopterin-induced cell death of V653. When the cells were coincubated with A23187 in the presence of aminopterin, cell viability was remarkably decreased at concentrations of more than 2 uM and DNA fragmentation was increased at concentrations of more than 0.2 uM. A23187 also induced cell death when the cells were treated with A23187 alone. When endogenous endonuclease activities of nuclei isolated from intact healthy cells and aminopterin-treated cells were compared for four different conditions, there were notable increases in the Ca2+/Mg2+ -independent and the Mg2+ -dependent endonuclease activity after incubation with aminopterin for 12 hours. In northern blot analysis, induction of c-myc gene was observed in aminopterin-treated V653 cell reached peak at 2 hours and thern decreased drastically.

Since Duhamel (1739), numerous experimental studies on the longitudinal growth of growing long bone have been reported. In Hales(1747) experience, growing long bone showed overgrowth after drilling in the tibia of chickens. David(1924) observed the fact that various degrees of shortening disappeared within 15 months after fracture of the femur in children and he concluded that fractures in children should be treated with the caution that the growing long bone has a tendency to increase in length after injury. Bisgard(1936) concluded that shortening from overriding of fragments in fractured extremities of children will frequently, but not invariablly, become partially or totally eliminated by the acceleration of growth which incidentaIly results from the inflammatory process, incited by trauma and fracture repair. Hass(1926) reported that interstitial proliferation of osseous tissue plays no part in the elongation of a growing bone, either in the mature bone or the young osteoid tissue bordering on the epiphyseal cartilage plate, and length growth of bone is entirely dependant on the purposeful multiplication of cartilage cells of the epiphyseal cartilage plate. Ham(1952) reported that the growth of long bone depends upon the interstitial growth of cartilage. This study was initiated to investigate the effects of fractures in the longitudinal bone growth of growing bone. Artificial fractures were made at two different sites in the diaphysis of the tibia in young rabbits. The operation for artificial fracture was performed under general anesthesia with ether. The type of fracture was an incomplete one, leaving a part of the posterior cortex of the tibia, in order to prevent the displacement of fractured fragments. In all of the cases, no cast immobilization was applied. After the fractures, follow up observations were made weekly till the 4th week, and thereafter at two week intervals, with roentgenographic, lethal measurement and histological examination. The results were as follows; 1) Longitudinal bone growth was increased from fracture of the diaphysis of growing long bone. 2) Compared with the control limb, tendency to overgrowth of growing bone was noted from the first week after the operation. 3) In follow up measurements, no growth inhibition was observed till the 10th week after the operation, but, thereafter, a tendency to reduce the proliferation of cartilage cells was noted. 4) In cases of fracture of the mid 1/3, the gorwing activity in the epiphyseal plate was increased more than from proximal 1/3 fractures. 5) The bony growth, accelerated by fractures in diaphysis of growing long bone without displacement was transient, and the prolonged overgrowth was compensated by the reduction of growing activity and premature closure of the epiphysis.

An appreciation of the range of normal variation and normal values for the pelvis and hip remains a continuing problem for the orthopedic surgeon in Korea. To help overcome this problem and to provide a comprehensive single source for this information, I have undertaken a study of 1037 unselected Korean subjects (605 normal males and 432 females) who varied in age from newborn to 86 years. The present study is concerned with normal angles and distances of the pelvis and hip, examined roentgenographically for statistical survey from January 1965 to August 1971 at Severance Hospital in Korea. The results of this study are as follows: 1. The value of the C-E angle, distance h, and distance d is increased according to increment of age but the value of the femoral neck shaft angle, acetabular angle, iliac index and interval of symphysis pubis is decreased with age. 2. The acetabular index in all age groups, iliac angle in the 1–3 months group, C-E angle in the 6–10 months group and the adult group over 18, interval of the symphysis pubis in the 4–22 year group, distance h in the 3–6 months group and the 4–8 year group, and distance d in the 1–3 months group show a difference between males and females. 3. There are differences between normal females and pregnant women in the interval of the symphysis pubis. Also the degree of relaxation of joints of the pelvis is higher in primigravida than multigravida. 4. The value for the femoral neck shaft angle is higher in Koreans than Europeans.

In order to determine the knowledge of, attitudes to, and practice of housewives toward health care in a rural area, a survey with questionnaire was carried out with 87 housewives who were sampled randomly from 6 villages in Sudong Myun, from April 16th to 21st, 1979. The following results were obtained. 1. Of the housewives studied, 61.5% knew that B.C.G. is a vaccine for T.B. prevention and 12.3% knew that D.P.T. is a vaccine for diphtheria, pertussis, and tetanus. 2. The vaccination rate of the children under six-year of the housewives studied was : polio 83.1%, B.C.G. 75.4%, D.P.T. 66.2%, and measles 55.4% respectively. 3. The vaccination rate was higher in children in the area near from the health subcenter than in those of the area further away. 4. Out of 87 respondants, 87.5% knew one or more methods of contraception for spacing children. These were ; loop 69.0%, oral pill 66.7% and condom 14.9% respectively. 5. Out of 87 respondants, 82.2% knew the methods of contraception for sterilization. These were : laparascopy 87.5% and vasectomy 16.9%. 6. Out of 87 respondants those who had experience using contraceptive methods were 70.1% and present users were 47.1%. 7. Contraception practice rate was higher in the group of housewives having middle school education or above than those having primary school education or less. 8. Functions of the health subcenter listed by respondents were : patients care 72.4%, family planning 31.0%, vaccination 23.0%, T.B. control 3.4%, health education 3.4%, infant birth delivery assistance 1.1% respectively. 9. Housewives who knew that there is a village health voluntary worker in their own village were 63.2%(55), and 58.2% of those who knew appreciated her activities. 10. Purpose of expenditure of Myun community health development funds listed by respondents were : aid for patient care 34.5%, aid for health subcenter operation 16.1%, and aid for Myun health development 6.9% respectively. 11. It seems that both of the distance from the health subcenter and the utility rate level of the village health voluntary worker are co-related to the B.C.G. vaccination rate of children. 12. It seems that both of the distance from the health subcenter and the utility rate level of the village health voluntary worker are not co-related to the rate of contraception practice.

Studies were conducted in rivers in Kyungpook Province, Korea from July 1970 to September 1974 to determine the stations where Parafossarulus manchouricus, the intermediate snail host of Clonorchis sinensis, are abundant, and the infection rates of these snails with the cercaria of Clonorchis sinensis. Snail collections were made during four consecutive summers(July to September in each year). Ten snail habitats were found. The population density of the snails per square meter of the river bottom ranged from 25 to 250. The highest population of snails was encountered at the Dong-chon station. Cercaria studies by means of the immersing and crushing technics indicated surprisingly low rate of Clonorchis sinensis infection among the snails examined. The proportion of infected snails in Kyungpook Province was 0.8 per thousand of all snails examined. Results indicated that the Parafossarulus manchouricus exists in limited areas within the rivers under study and the infection of the snail with the cercaria of Clonorchis sinensis is very low.
