  • The study was conducted to investigate on in vitro developmental rates of bisected bovine embryos co-culture in 10% FCS+TCM-199 media containing hormones, oviductal epithelial cells and cumulus cells 0 to 7 days after bisection. In vitro developmental rates was defined as development rates on in vitro culture or FDA-test. The results are summarized as follows : 1. In vitro developmental rates of bisected bovine embryos co-cultured in 10% FCS+TCM-199 media containing PMSG+hCG, PMSG+$\beta$-estradiol, hCG+$\beta$-estradiol, PMSG, hCG 0 to 3 days and 4 to 7 days were 16.7~30.0% and 11.1~25.0%, respectively. In vitro developmental rates of bisected embryos co-cultured in 10% FCS+TCM-199 media containing hormones significantly higher than that of non co-culture. 2. In vitro developmental rates of bisected bovine embryos co-cultured 10% FCS+TCM-199 media containing oviductal epithelial cells 0 to 3 days and 4 to 7 days were 25.0% and 22.2%, respectively.

  • Purpose: This study was conducted to estimate the prevalence of questionable development according to developmental screening testing for children, and to explore biological and environmental risk factors of developmental delays. Method: The study participants were 153 children under two years of age. A questionnaire and Home Observation for measurement of the Environment (HOME) inventory were used to collect data, and Korean Denver II was administered. Results: The overall prevalence of questionable development was 11.1%. Significant differences in biological factors between the normal development group and questionable development group were the rate of prematurity, twins, the educational level of mother and father's and the presence of an illness in the mother (p<.10). Maternal acceptance in HOME was significantly different between the two groups. The factors related to questionable development that were significant in the logistic regression analysis were prematurity (OR=3.56, p=.026), and maternal acceptance in HOME score (OR=.629, p=.028). Conclusion: Early developmental screening tests seem necessary for all children, especially for prematurely born children. Also, child rearing environments were identified as significant factors in the development of all children. These findings suggest that the HOME scores might be useful in identifying children at risk for developmental delays, and that interventions for these children will probably be more effective if their mothers are helped to provide a more appropriate social environment.

  • Purpose: To develop an Infant Developmental Assesment Scale appropriate for Korean infants that includes cultural context. Method: The total sample included 990 infants aged birth to 24months. The developmental tests were conducted at hospital well baby clinic, daycare centers, public health centers and homes located in city, urban and rural areas. Item analysis was done to examine content validity of the scale. Test responses were analyzed by SPSS to examine the inter-rater reliability, and construct validity. Result: Based on the naturalistic observation and analysis of other developmenta l instruments, 260 Korean infant developmental items were created. The mean score of the developmental quotient of 966 infants was 101.63±10.89. Correlation coefficient of inter-rater reliability was .99. In addition, 84.6% of total items showed Kappa .70 and above. The development quotient was significantly different depending upon the residential area and father's occupation, therefore, construct validity using known group technique was supported. Conclusion: The developed instrument can be used to assess the development of handicapped infants, as well as normal infant's general abilities and to study individual differences within the normal range for Korean.

  • The Denver Developmental Screening Test was devised to provide a simple method of evaluating the developmental status of infants and preschool children. To assess the development of Korean children, 667 children (390 boys and 277 girls) between the ages of 2 weeks and 6 years who live in Kwangju city and rural areas in Chonnam were examined according to the DDST. The ages at which 25%, 50%, 75%, and 90% of the children performed each item were calculated for the entire sample. The results of these were compared with the norms of Denver children and other related previous studies in Korea. The development of the boys was also compared with that of the girls, and further the test results of city children and country children were also compared. Girls performed the DDST items in personal-social, fine motor-adaptive and gross motor sectors slightly earlier than boys. In general, however, there were no significant differences in the developmental rate between boys and girls. In all four sectors of the DDST, urban children performed the items significantly earlier than rural children. In comparing Korean children and Denver children, Korean children tended to perform gross motor and personal-social items at a slightly earlier age than Denver children. In the language sector, Denver children tended to perform a little earlier than Korean children. But on the whole there were no significant differences in developmental status between Korean and Denver children. It should be noted that a few items, such as“Uses plurals”, needed to be changed due to the structure of Korean language.

  • The purpose of this study is to examine the effects of sensory integration training on children with developmental delays. To achieve this goal, an educational experiment is conducted in five main areas: gross motor ability, fine motor ability, adaptive ability, language and social ability in children with developmental delay. The study subjects were children with developmental delays aged 3-6 years diagnosed at Beijing Institute of Pediatrics and Beijing Medical University and received sensory integration intervention and homebased training at the Golden Rain Forest Beijing Tongzhou Center from 2018 to 2021. According to the purpose of the analysis, the data collected are subjected to descriptive statistics using SPSS 21.0 statistical program, Two-way MANOVA analysis, and data analysis method of multivariate analysis is used to process the collected data. In addition, a total of 39 subjects were selected, including 19 children who received sensory integration training and 20 children who only received family training. The results show that the sensory integration training group outperformed the home training group in all aspects and developmental quotient, but the home training group also showed higher levels of significance for improvements in gross motor, fine motor and developmental quotient.

  • Background: Korean Red Ginseng has been widely used in traditional oriental medicine for a prolonged period, and its pharmacological effects have been extensively investigated. In addition, Angelica gigas and deer antlers were also used as a tonic medicine with Korean Red Ginseng as the oriental herbal therapy. Methods: This study was conducted to evaluate the potential toxicological effect of KGC-HJ3, Korean Red Ginseng with angelica gigas and deer antlers, on reproductive and developmental functions including fertility, early embryonic development, maternal function, and embryo-fetal development. KGC-HJ3 was administered by oral gavage to Sprague-Dawley rats (22 animals per sex per group) at dose levels of 0 mg/kg (control), 500 mg/kg, 1000 mg/kg, and 2000 mg/kg to evaluate the potential toxicological effect on fertility and early embryonic development. In addition, KGC-HJ3 was also administered by oral gavage to mating-proven Sprague-Dawley rats (22 females per group) during the major organogenesis period at dose levels of 0 mg/kg (control), 500 mg/kg, 1000 mg/kg, and 2000 mg/kg to evaluate the potential toxicological effect on maternal function and embryo-fetal development. Results and conclusion: No test item-related changes in parameters for fertility, early embryonic development, maternal function, and embryo-fetal development were observed during the study period. On the basis of these results, it was concluded that KGC-HJ3 did not have toxicological potential on developmental and reproductive functions. Therefore, no observed adverse effect levels of KGC-HJ3 for fertility, early embryonic development, maternal function, and embryo-fetal development is considered to be at least 2000 mg/kg/day.

  • The problems of growth & development due to maladjustment are gradually increasing while need for the treatment of children's diseases is decreasing. The level of developmental deficiency or delay correlates with neonatal birth weight and also with gestational age, i.e. degrees of prematurity. There-fore, developmental defects and potential risk factors' are more Common in premature infants than in full term infants. The purpose of this study is to define the difference in the growth at developmental status between premature and full term infants, and to define the relation between the developmental status and the physical growth during the first 3 years' Data were collected from January 10, 1985 to April 6, 1985 at 3 hospitals including St. Mary's Hospital, and through home visiting. The subjects of this study consisted of 79 Premature infants (G.A. <37wks. & B.W. <2.5kg) and 94 full term infants (G.A.≥37 wks. & B.W.≥2.5kg). The study method used was a questionnaire, anthropometric assessment and DDST for normative data of growth & development. The collected data were analyzed using descriptive statistics, chi-square test and t-test. The results of the study were as follows: Hypothesis: 1 : That the prematures will differ from the full term infants in the physical growth status during the first 3 years was partially supported (p<0.02) : The prematures reached up the full term infants in the physical growth status in the first 6 months. And, the first hypothesis was supported (P<0.01) : There are more cases which is below‘the Korean children's physical. growth standards’in prematures than in full term infants. Hypothesis 2 : That the prematures will differ from the full term infants in the developmental status during the first 3 years was supported (P< 0.001);‘Normal’developmental status due to DDST was less in prematures than in full term infants. And, the second hypothesis was Partially supported (P<0.02) : The developmental status of the pre-matures was different from that of the full term infants within the first 3 months by analysis of passed items in DDST, Hypothesis 3 : That the prematures' developmental status will relate to their physical growth during the first 3 years was supported (P<0.001) : If the prematures' developmental status is in delayed status, then, their physical growth status is also in delayed status. This study shows that the prematures differed significantly from the full term infants in the growth at developmental status during their infancy. This means that the nurse can foster the growth & development of the prematures by supportive care during their infancy. Further longitudinal study is needed to verify these findings for the environmental factors.

  • Colorectal cancer (CRC), now the third most common cancer across the world, is known to aggregate in families. USP7 is a very important protein with an important role in regulating the p53 pathway, which is critical for genomic stability and tumor suppression. We here genotyped eight SNPs within the USP7 gene and conducted a case-control study in 312 CRC patients and 270 healthy subjects in the Chinese Han population. No significant associations were found for any single SNP and CRC risk. Our data eliminate USP7 as a potential candidate gene towards for CRC in the Han Chinese population.
