Purpose: To compare the protective effects of saponin and non-saponin Sun-ginseng extract fractions in a selenite-induced rat cataract model. Methods: A total of 101 Sprague-Dawley rat pups were divided into four groups by treatment: Sun-ginseng, saponin fraction, non-saponin fraction, and control. For induction of cataracts, sodium selenite 15 nmol/g was injected subcutaneously in 13 day-old rat pups. Sun-ginseng extract 100 μg/g (Group I, Ginseng Science, Seoul, Korea), saponin fraction 100 μg/g (Group II), non-saponin fraction 100 μg/g (Group III), and phosphate buffered saline (Control group) were injected intraperitoneally every two days for a total of seven injections. The rats were sacrified and their lenses were dissected and photographed at day 7 and 14, and the cataracts were graded according to the ratio of the cataract area to the total lens area. The blind method was used for the evaluation of the cataract area. Results: At day 14, cataract formation rates (CFR) were 33.3% in group I, 76.4% in group II, 41.2% in group III, and 77.7% in the control group. The mean cataract area (MCA) was 13.4±20.8% in group I, 14.4±11.7% in group II, 5.7±7.7% in group III, and 15.8±12.1% in the control group. Group III showed statistically significant results compared with those of control group (CFR p=0.001, MCA p=0.001). We observed significantly lower incidence and smaller mean cataract area in Group I and Group III at day 7 compared with the control group (Group I, CFR p=0.018; Group III, CFR p=0.032, MCA p=0.005). Conclusions: The protective effects of Sun-ginseng extract are caused by the components in the non-saponin fraction, not by those in the saponin fraction, in a selenite-induced cataract rat model.

The purpose of this research was to investigate the effect of TV advertising and adult's comment on children's food choices. The subjects were 56 elementary school children(1th graders). The children were randomly assigned to four treatment conditions. Each experimental group viewed TV program with/without TV commercial and with/without adult's comment. The comment was about pronutritional educational message. After experiments, all children was interviewed induividually. The data were analyzed with two-way ANOVA. The finding was TV advertising was effective, children choiced advertised food. Adult's comment was not effective in statistically.

This article points to some aspects of parent-child relationship concerning the exposure of child to TV. A series of studies are reviewed dealing with theoretical frames about TV acceptance, children's time with TV, preference and comprehension about TV program, parent-child coviewing, parental control over children's TV viewing, parent's use of TV as babysitter, and finally some methodological issues.

The purpose of this study was to investigate the stress of father on child rearing, especially focused on the change of role expectancy. The subjects were 97 preschool children's fathers and 108 mothers to compare. Parenting Stress Index were utilized to assess. The items have been assigned to three sub-scales( distress of parent, dysfunctional parent-child interaction, children's degree of bother ). The data were analyzed with t-test and stepwise multiple regression. The results showed that paternal stress is less than maternal one. There were significant differences in total score on PSI, except in dysfunctional parent-child interaction. Especially distress of parent is the most different, the scores of fathers' stress was lower than mothers'. And the level of parenting stress is negatively related to the one of parents' education.

The purpose of this research was to investigate the significant features of TV advertising in the children's hours. 102 commercials were sampled from three channels (KBS1, KBS2, and MBC) between April 18 and April 28, 1989. For content analysis, study codes were used as instruments. The data were analyzed with frequency, percentage, and mean. The findings were as follows : First, less than half of commercials appealed to children. Second, sugared foods were most frequently advertised. Third, most of commercials were appealed to audience emotionally. Fourth, special effects that might tend to mislead a child viewer were too much shown. Fifth, usually male adult played a major role, female played a minor role in commercials. Sixth, for the most part adult male spoken for the product. And sex-role stereotype were expressed. Seventh, a great number of commercials were titled the foreign terms.
