Periodontal surgery can be directed to remove the irritants from the tooth surface and reduce the periodontal pocket. The purpose of this study is to compare the clinical effects after between modified Widman flap and modified flap in periodontal patients. Ninety six molar area teeth of 9 patients were used. One of sextants performed a modified Widman flap, while the other side performed a modified flap. After initial periodontal therapy, the following measurements prior to surgery(baseline) were taken : pocket depth, gingival recession, clinical attachment level, tooth mobility, bleeding on probing. Also these measurements were taken at 4 weeks, 8weeks, and 12 weeks after surgery. Significant decrease of pocket depth was shown in both techniques, and the degree of decrease was significant in modified flap than modified Widman flap at 12 weeks. Significant increase of gingival recession was shown in both techniques, and the degree of increase was significant in modified Widman flap than modified flap at 4 weeks, 8 weeks, and 12 weeks. Significant attachment gain was shown in both techniques, and the degree of increase was significant in modified flap than modified Widman flap at 4 weeks, 8 weeks, and 12 weeks. Significant increase of tooth mobility was shown in both techniques at 4 weeks, but the decrease of tooth mobility was shown at 12 weeks. Greater decrease of bleeding on probing was shown in both techniques at 4 weeks. Modified flap was better than modified Widman flap in the decrease of gingival recession and the attachment gain. These results indicate that modified flap operation is better than modified Widman flap operation in the effect of periodontal treatment.

Background: The U.S. Food and Drug Administration has prohibited epidural steroid injection (ESI) with particulate steroids. Thus, this study aimed to compare the efficacy and safety of ESI with two nonparticulate steroids, dexamethasone and betamethasone. Methods: The eligible patients (n = 600) who received ESI (0 week) with dexamethasone (ESI-dexa) or betamethasone (ESI-beta) had follow-up visits at 2, 4, and 8 weeks with a phone interview at 12 weeks. The primary endpoint was the proportion of effective responders without pain or who were much improved at 2 weeks. The secondary endpoints were the proportion of crossover injections at 2 weeks; changes in the visual analog scale (VAS) and disability index scores at 2, 4, and 8 weeks; the number of additional ESIs in 12 weeks; the number of participants having spinal surgery, as well as the incidence of adverse events over the 12 weeks. Results: The proportion of effective responders at 2 weeks was not different between ESI-beta (72/216, 33.3%) and ESI-dexa (63/200, 31.5%; P = 0.670). Adverse events were more common with ESI-dexa (40/200, 20.0%) than with ESI-beta (24/216, 11.1%; P = 0.012). VAS scores decreased more with ESI-beta than with ESI-dexa at 2 weeks (difference, 0.35; P = 0.023) and 4 weeks (difference, 0.42; P = 0.011). The disability score improved significantly more with ESI-beta compared with ESI-dexa at 2 weeks (difference, 3.37; P = 0.009), 4 weeks (difference, 4.01; P = 0.002), and 8 weeks (difference, 3.54; P = 0.007). Conclusions: Betamethasone would be more appropriate for ESI.
This experiment was conducted to find out the effects of the six different feeding methods on the development of body weight, testis, comb and pituitary gland, and the sexual maturity of White Plymouth Rock cockerels. From hatching to 22 weeks of age, the weights of whole body, testis, comb and pituitary gland, and the histological changes of testis and the semen characteristics were checked every other week. The results obtained in this expeniment were as follows: 1. The growth rates of the self-feeding groups were faster than those of the limited feeding groups (70 percent of the self-feeding) by about 2 weeks. The weights of testis and comb showed the most marked increase at 20 weeks of age in the self-feeding groups and at 22 weeks of age in the limited feeding groups, respectively. 2. The weights of pituitary gland from hatching to 22 weeks of age at all observation weeks were not recognised significantly among the compared groups except 4, 14 and 16 weeks of age. 3. Correlations between week of age, body weight, testis, comb and pituitary gland, in the course of 22 weeks, were highly significant. 4. The diameters of lumina and tubules in the seminiferous tubules increased very slowly until 10 weeks of age. They showed the most marked increase at 12 weeks of age in the self-feeding groups and at 14 weeks of age in the limited feeding groups, and then continuously increased until 32 weeks of. age. 5. Primary spermatocytes appeared at first at 8 weeks in the all treatment groups, Secondary spermatocytes appeared at first at 10 weeks in the self-feeding groups and at 12 weeks in the limited feeding groups. At 14 weeks of age spermatids and spermatozoa were found at first in the self-feeding groups but spermatids were found in the limited feeding groups. 6. Age of the first ejaculation was between 14 and 16 weeks of age in the all treatment groups. The Average semen. volume and sperm concentration ranged from 0.1-0.2$m\ell$/ ejaculate and 5.6-9.8${\times}$10$\^$8/ sperm/$m\ell$ at the age of the first ejaculation but 0.30-0.35$m\ell$/ ejaculate and 22.4-42.7${\times}$10$\^$8/ sperm int at the 20 weeks of age in the all treatment groups.
This study was designed to investigate the effects of weight control and changes in serum components using a commercial uncooked food diet on 36 obese women over a period of 8 weeks. The subjects had uncooked food (40 g) with milk or soymilk twice a day instead of meals. The mean body weight and height measurements of the subjects at the outset were 69.1 $\pm$ 9.3 kg and 159.5 $\pm$ 4.4 cm, respectively. Initial daily calorie intake was 103.6 % of RDA, but was significantly lower at 4 and 8 weeks. The subjects showed a significant reduction in weight, body fat mass (p<0.05), anthropo-metric value and skinfold thickness during the experimental period. Hip and upper thigh girth were 102.7 $\pm$ 6.4 cm and 61.7 $\pm$ 4.3 cm at the outset, and fell to 99.3 $\pm$ 5.0 cm and 58.8 $\pm$ 4.1 cm after 8 weeks. The most significant reduction was in abdomen skinfold thickness (p < 0.05) , which went from 32.4 $\pm$ 8.7 mm at first to 24.2 $\pm$ 8.3 mm in after 8 weeks. Serum albumin levels were higher at 4 and 8 weeks than initially but the figures for all of the subjects were within the normal range. Hemoglobin and blood glucose levels were also within the normal range during the experimental period. Initial serum triglyceride level was 110.5 $\pm$ 49.5 mg/dl but fell to 93.2 $\pm$ 48.5 mg/dl after 8 weeks. Our results show that uncooked foods are effective in the diet therapy of obese women.

Purpose: The effect of platelet-rich plasma(PRP) on osteogenesis of marrow-derived osteoblasts on histomorphometric analysis in the mandible of rabbit was assessed. Materials and Method: Bone marrow cells were obtained from iliac bone of rabbits and were cultured in a Dulbecco's Modified Eagle's Medium(DMEM) with Dexamethasone, L-Ascortic acid, ${\beta}$-Glycerophosphate to proliferate and differentiate into osteoblasts for $4{\sim}5$ weeks. The expression of osteogenic mar-kers was detected by reverse transcription-polymerase chain reaction(RT-PCR) and silver nitrate stain. Then we prepared bony defects in the mandible of rabbit, 10.0mm in diameter and 4.0mm deep, by trephine bur. In the control group, the defects were filled with autogenous bone and cultured osteoblasts. In the experimental group, the defects were filled with autogenous bone, cultured osteoblasts and PRP. 2 weeks, 4 weeks, 8 weeks later, each group was evaluated with histological and histomorphometric analyses. Results: In vitro, osteoblasts were identified on RT-PCR and silver nitrate stain. According to histological observation, at 2 weeks well-developed anasto-mosing newly-formed woven bone was observed, at 4 weeks anastomosing newly-formed woven bone having osteoblastic activation was observed, and at 8 weeks thick newly-formed woven bone was observed in both control and experimental groups. According to histomorphometric analysis, there were 1.5% more newly-formed bone volume in experimental group than control group at 2 weeks, 28.4% more at 4 weeks, 4.3% more at 8 weeks. Particularly there were significant differences in bone volume at 4 weeks and 8 weeks new bone. Conclusion: Our results demonstrated PRP may enhance osteogenesis of marrow-derived osteoblasts at 4 weeks, 8 weeks.

This study describes a surgical technique and evaluates the clinical outcomes in small breed dogs with cranial cruciate ligament rupture (CCLR) treated with tibial plateau leveling osteotomy (TPLO). Seven skeletally mature dogs weighing less than 15 kg underwent unilateral TPLO to stabilize the stifle joint with CCLR. Clinical evaluation was performed via visual lameness score, range of motion (ROM), and thigh girth circumference (TC). Postoperative complications were recorded. All patients reached a grade 1 score at 1 week and grade 0 at 8 weeks postoperatively. The mean operated limb extension angle was 98.11%, 99.07%, and 98.73% of the mean extension angle of the contralateral limb at 4 weeks, 8 weeks, and 12 weeks postoperatively, respectively. The mean operated limb flexion angle was 98.07%, 95.88%, and 96.35% of the mean flexion angle of the contralateral limb at 4 weeks, 8 weeks, and 12 weeks postoperatively, respectively. The mean TC of the operated limb was 92.95%, 93.68%, and 95.44% of the mean TC of the normal limb at 4 weeks, 8 weeks, and 12 weeks postoperatively, respectively. Our outcomes for TPLO in small breed dogs are not worse than those previously reported for large breed dogs. Based on the result in the present study, CCLR in small dogs can be successfully managed with TPLO, as done in large breed dogs.
Nine rabbits were fed with Clonorchis sinenis metacercariae (MC) and the blood samples chronologically obtained were analyzed biochemically. Rabbits Infected by less than 100 flukes were grouped into Group I, and by 100-250 flukes into Group II. The serum level of alanine amlnotransferase (ALT) was increased from 3 weeks after the Infection of the metacercariae (AIM) and showed a peak at 8 weeks, and decreased from 12 weeks ASM. The serum level of aspartate aminotransferase (AST) was raised to $92.3{\;}{\pm}{\;}65.4{\;}U/L$ at 3 weeks AIM and stayed high until 8 weeks, then lowered thereafter. The serum level of ${\gamma}-glutamyl$ transpeptidase (${\gamma}-GT$) was increased rapidly to the highest value ($18.9{\;}{\pm}{\;}14.6{\;}U/L$) at 16 weeks ASM, and decreased to the control level after 20 weeks. The serum level of alkaline phosphatase (ALP) was headed down from the early infection to 52 weeks AIM. The serum cholesterol level was increased from 8 weeks and reached at a peak 16 weeks AIM, and decreased thereafter to the control level. It is suggested that serum ALT, AST, ALP and ${\gamma}-GT$ tests be useful to diagnose the early infEction of C. sinensis.
Breast milk samples collected from 8 areas of 59 lactating women were analysed by atomic absorption spectrophotometry for copper, zinc and manganese concentrations. The results were as follows; 1. The mean levels of Cu, Zn and Mn in the total samples were $342.6\pm138.9{\mu}g/l$ of Cu, $2.01\pm1.44mg/l$ of Zn and $8.67\pm5.12{\mu}g/l$ of Mn. 2. The mean Cu levels by lactation periods were $504.5\pm166.2{\mu}g/l$ in 1-4 weeks, $345.0\pm100.0{\mu}g/l$ in 5-12 weeks, $276.4\pm84.8{\mu}g/l$ in 13-36 weeks and indicated decreasing concentrations by the post-partus period progressed. (p<0.01) 3. The mean Zn levels were $3.50\pm2.10mg/1$ in 1-4 weeks, $2.08\pm0.79mg/1$ in 5-12 weeks, $1.38\pm0.91mg/l$ and showed the decline trend by the lactation periods. (p< 0.01) 4. The mean levels of Mn were $8.964\pm3.313{\mu}g/l$ in 1-4 weeks, $7.971\pm6.066{\mu}g/l$ in 5-12 weeks, $8.357\pm4.966{\mu}g/$ in 13-36 weeks and didn't indicate significant decreasing concentrations by the lactation periods.

This study was designed to investigate the effects of behavior medication and aerobic exercise on the degree of obesity, eating behavior, depression and self esteem among adolescent girls who were overweight and obese. Forty seven subjects were selected from one girl's middle school located in Seoul. Seventeen girls received the behavior modification program by joining 60-90 minute group session weekly. Behavior modification, in this study, consisted of self-monitoring, changing patterns of life style and attitudes, teaching nutrition and physical activities, and asking personal help. The aerobic exercise program was given to 16 girls 3 times per week with 60 minutes each time. Forteen girls received both behavior modification and aerobic exercise. These interventions continued for 8 weeks. Changes after intervention were examined twice after 4 weeks and 8 weeks for degree of obesity and once after 8 weeks only for eating behavior, depression and self esteem. The results were as follows ; 1. Degree of obesity was significantly decreased after 4 weeks and 8 weeks in 3 groups. Degree of obesity after 4 weeks and 8 weeks were not significantly different among 3 groups. 2. The mean score of eating behavior related to obesity decresed significantly after intervention in the behavior modification group only. There was significant difference in eating behavior among 3 groups after intervention. 3. The behavior modification group showed no significant changes in depression and self esteem after intervention. In the aerobic exercise group and group who participated in both behavior modification and aerobic exercise, the level of depression decreased significantly and the level of self esteem increased significantly. There were no significant differences in the level of depression and self esteem among 3 groups after intervention. These findings indicate that behavior modification might be effective in decreasing degree of obesity and eating behavior related to obesity, aerobic exercise be effective in decreasing degree of obesity and the level of depression, and also in increasing the level of self esteem.
Korean MEJUES were prepared by means of ordinary, Improved and compromised methods, and analyses of the changes in various chemical compositions of the Soy-sauces throughout the fermentation period of 10 weeks. Now, their result, are as the following as. (1) In all of the Soy-sauces under study the content of organic acids showed a slight increase upto 4 week, and a marked increased after this period. (2) In all of the soy-sauces the total nitrogenous content indicated a rapid increase until 4 weeks, and a slower increase after this. (3) In all of the soy-souses, the content of free amino acids displayed a liner proportional increament until 8 weeks and then slower increose. (4) In all of the soy-souses the content of reducing sugars indicated a slight increase until 4 weeks, and after this it showed a rapid decrease until 4 weeks, in the improved soy-souses and, then maintained an almost flat curve. In the ordinary and Compromised soy-souses there was a rapid decrease in reducing sugars until 6 weeks, and then an almost 리at curves. (5) In the ordinary soy-sauce the SAMWOL-ZANG-BUB(soy-sauce prepared in March) is considered to be based on a comparatively scientific ground during the fermentative period. (6) In order to improve the taste in ordinary soy-sauce it is favorable to delay the period of preparation. The adequate period appears requires 8 weeks at least. Accordingly it is recommended to mix the materials with carbohydrate source. (7) In the improved soy-sauce according to the SAMWOL-ZANG-BUB of ordinary soy-sauce it is thought that 8 weeks were adequate for the fermentation. (8) The compromised method may be recommended for the improvement of nomemade soy-souce, and it may be also superior to the ordinary soy-sauce in quality.
