  • Many patients with malignancies of the head and neck undergo radiation therapy, either as the only method of treatment or in combination with surgery. Radiation therapy has great effect in the case of fairly advanced malignancies which can't be operated radically. But the complication of radiation therapy arise because of damage to the peri- and operated area. It is fully known that irradiated tissue shows retarded healing process in the skin, mucosa and especially vascuslar tissue. The purpose of this study was to observe the healing process of irradiated free or island flap after operation. As Experimental Models, Femoral arterial and venous anastomosis (Group 1), Epigastric-island flap (Group 2) and free Epigastric falp(Group 3) with irradiated postoperative 24 hrs were made on 30 rats/group. As Control Model(Group 4), Free Epigastric flap was not irradiated after operation was chosen on 30 rats. The amount of irradiation was single fraction of 20 Gy using as linear megavoltage accelerator. Difference between Experimental and Control group was evaluated by the method of clinical examination, histopatholoical findings, biochemical analysis and DNA activity at postoperative 1, 3, 7, 14 and 28 days. The results were as follows, 1. Skin color and new epithelization in group 2 and 3 was similar to control group clinically. 2. Postoperarive patency of femoral artery and vien showed 5% and 22% of ischemity. 3. The externa, media and intima of irradiated femoral artery and vein were similar to control group histopathlogically. 4. Granulation and collagen tissue accumulation of irradiated groups were more active due to degenerative and fibrotic changes than control group at postoperative 7 days histopathologically. 5. The hydroxyproline content of all experimental groups were reduced till 14 days and the group 2 was most prominent at postoperative 7 and 28 days(p<0.05). 6. DNA activities of all groups were reduced till 3 days, but begun to recover at 7 days and more activities in control group than irradiated group(p<0.05). Based on the above results, the clinical healing process of free flaps with irradiated postoperative 24 hrs little difference from control group without complications.

  • This experiment was done to investigate the effects of Ojajiwhangeumja(OJWEJ) to the symptoms of senility. To prove the effects of OJWEJ we injected scopolamine(1mg/kg) to the vein of rats. And we measured the blood cells(WBC, RBC, Platelet), constituents of serum(BUN, creatinin, glucose, uric acid), endurance of films of the red blood cell to erythrocyte hemolises, the activity of cholinesterase in serum, TBA and the activity of catalase, SOD in the purified microsome of brain tissue of rats. The results were as follows; 1. The number of white blood cells, platelet was increased significantly in the group treated by OJWEJ in comparison with control group. 2. The number of BUN, creatinin, glucose of serum decreased significantly in the OJWEJ treated group compared with control group. 3. The erythrocyte hemolises in red blood cells restrained significantly in the group treated by OJWEJ in comparison with control group. 4. The activity of cholinesterase in OJWEJ treated group increased significantly compared with control group. 5. The amounts of malondialdehyde of serum decreased significantly in the OJWEJ treated group in comparison with control group. 6. The catalase in the microsome of rat brain was activated significantly in the group treated by OJWEJ compared with control group. 7. The superoxide dismutase in the group treated by OJWEJ activated significantly in comparison with control group. According to this experiment it is suggested that OJWEJ accelerates the activity of colinesterase and restrains the creation of erythrocyte hemolises and accumulation of senile substance. But I look forward to see the further research to be made.

  • The purpose of this study is to investigate the effects of Ginseng saponin on the cadmium which is widely distributed in the environment, results in immune system alteration. For the experiments, 125 mice of ICR strain were used. The experimental groups were divided into 5 groups a control, a cadmium alone treatment group, three Cd and saponin (10, 50, 100 mg/kg) combined treatment groups. The mice were allocated 25 to each group and observed for 8 weeks. The results of experiment are as follows: 1. Body weight growth rates during 8 weeks were as this control group 36.47%, Cd alone group 32.48%, saponin combined treatment group (10, 50, 100 mg/kg) 32.49%, 39.17%, 24.27% respectively. 2. In all groups, the relative weights of liver and kidney were increased, compared with control group. In the case of spleen, saponin combined treatment group (50, 100 mg/kg) was high to the significant level compared with a control group (p<0.05). Thymus was not. 3. On blood lymphocyte count observation, Cd alone treament group has 25.6% less than control group, and saponin combined treatment group have increasing trends. but in thymus and spleen, there was no trends like blood. 4. On antibody titer, there was no difference among groups. 5. On total serum protein, saponin (100 mg/kg) combined treatment group was high to significant level compared with control group (p<0.05), and other treatment groups have increasing trends. 6. Cd accumulation in kidney was higher than in liver, and all treatment groups were high to the very significant level compared with the control group (p<0.05), but there was no difference among groups. From the results of this study, it can be concluded that the oral administration of Cd results in alteration of immune system and Ginseng saponin prevents this effect. But, Cd accumulation was not affected by saponin.

  • This study was designed to investigate the effects of a sensory stimulation program on the growth (weight, height, head circumference, and chest circumference), behavioral development, behavioral states, and the heart rate of the infants. A total of 23 infants of 2 weeks old were divided into sensory stimualtion group (11 infants) and control group (12 infants). The infants of sensory stimulation group had received sensory stimulation for 6 weeks. Sensory stimulation program was composed of tactile and kinesthetic stimulation. We assessed growth, behavioral state and heart rate every week and behavioral development every 2 weeks. The results were as follows: 1. Body weight in sensory stimulation group, from two weeks after the sensory stimulation program, was significantly increased more than control group, but there was no significant difference in height, head circumference, and chest circumference between the two groups. 2. Behavioral developmental score of sensory stimulation group was significantly higher than that of control group from two weeks after the sensory stimulation program. Developmental states of sensory stimulation group showed more 'high average developmental state' than the control group from 4 weeks after sensory stimulation program. 3. Behavioral states of sensory stimulation group after the sensory stimulation program, the 'sleeping state' was significantly increased more than control group. The 'awakening state' and the state of fuss or crying were significantly less than those of the control group. 4. The heart rate of the sensory stimulation group after the sensory stimulation was significantly lower than the control group. These results indicate that the sensory stimulation program decreases heart rate and improves the sleeping state to be effective on promoting the growth and development of the infants. In view of these experiments, we suggest sensory stimulation program might be considered as a nursing intervention for growth and development of the infants not only in clinical settings but also at homes and in the communities.
