The purpose of this study was to investigate the effects of dietary purple sweet potato(lpomoea batatas) powder on serum lipid levels and antioxidative enzymes in normal and pretective effect on hepatotoxicity rats induced by carbon tetrachlolide. Four groups of rats (3-week-old inbred Sprague-Dawley male rats) were normal rats fed control diet(C)_(1) induced hepatotoxicity rats fed control diet(EC)_(1) normal rats fed purple sweet potato diet(P), and induced hepatotoxicity rats fed purple potato sweet diet(EP). Rats were induced by single injection of 50% carbon tetrachloide(0.1 mL/100 g B.W., i.p.). The rats were fed ad libitum each of the experimental diet for 5 weeks. After 5 weeks the rats were sacrificed and activities of antioxidant enzymes and lipid peroxidation products were determined in their liver homogenates. But serum concentrations of lipid was not significant in all groups. Serum alanine aminotransferase(ALT/GPT) and aspartate aminotransferase(ALT/GPT)of the EC and EP groups were heigher than the C and P groups. The hepatic glucose 6-phosphatase(G9Pase) activity of the group fed purple potato diet(P) was lower than the other groups(p<0.05). However, The glutathione peroxidase(GPx) activities was not statistically different between the groups. Renal glutathione S-transferase(GST) activity of the EC and EP groups were lower than the C and P groups(p<0.05). In conclusion, these results suggest that purple sweet potato is believed to be possible protective effect on hepatotoxicity rats induced by carbon tetrachlolide.

Pineapple에 대하여 人爲開花誘導를 時期別로 處理하여 生育 및 收量에 미치는 영향을 究明하기 爲하여 本 試驗을 遂行하였다. 그 結果를 要約하면 다음과 같다. 草長은 人爲開花誘導 處理가 늦을수록 길어지는 傾向을 보였으며 抽苔始는 品種에 따라서 다른 樣相을 보였다. 開花始는 "Sarawak"에서 6月30日 處理區가 가장 짧은 期間에 나타났고 7月30日 處理區는 가장 길었으며 "Special amarello"에 있어서는 處理時期가 늦을수록 길어지는 傾向을 보였다. 成熟期는 두 品種 共히 處理時期가 늦을수록 늦었으며 果重은 5月30日, 6月30日 處理區가 7月30日 處理區에 比해서 越等하게 무거웠다. 두 品種 共히 處理時期는 草長, 開花始, 開花期와는 正의 相關을 보여 處理時期가 늦을수록 草長을 길었고 開花始, 開花期는 늦었다. 果重은 開花始 및 開花期와 "Sarawak"에서 正의 相關을 보였으나 "Special amarello"에 있어서는 負의 相關을 보였다. This study was carried out to determine the effects of artificial flowering induction in pineapple. The results obtained are summarized as follows. The plant height tended to increase with delaying artificial flowering induction from May 30 to July 30. In 'Sarawack' the number of days from the inflorescence head emergence to the first flower opening was shortest in June 30-treated plants and longest in July 30-treated plants. In 'Special amarello', however, days to the first flower opening increased with delaying treatment. Maturity of two cultivars was postponed as treatment was delayed from May 30 to July 30. Fruit weight of two cultivars was markedly heavier at the plots treated on May 30 to and June than at the plot treated on July 30. Treatment dates were positively correlated with plant height and days to the first and central flower opening in two cultivars indicating that the earlier the treatment, the longer the plant height and days to the first and central flower opening. Fruit weight was positively correlated with days to first and central flower opening in Sarawack bu negatively in Speciall amarello.

We intended to know whether all of the patients with asymptomatic microscopic hematuria should be urologically investigated routinely. We reviewed the medical records with asmptomatic microscopic hematuria from January 1995 to December 1997. Urological studies included intravenous urography or ultrasonography, urine cytology, cystoscopy and biopsy, urine AFB smear and culture and urine PCR for AFB. The age with patients ranged from 9 to 74 years(mean age: 39.7 years). Benign diseases were found in elderly patients and patients with high degree of hematuria, but there was no patients who had urological malignant disease. According to the results, we suggest that follow-up with urine cytology is sufficient to younger patients or low degree of hematuria with asymptomatic microscopic hematuria.

We determined whether residual fraction might be able to differentiate obstructive from no obstructive voiding dysfunction in gray zone of lower urinary tract symptom. A total of 47 patients (mean age plus or minus standard deviation 64.4 ± 7.1) with maximum flow rates between 10 and 15 ml. per second were received transurethral resection of the prostate and the duration of follow-up was ranged from 2 to 20 months (mean plus or minus standard deviation 9.7 ± 5.1). Uroflowmetry and post-void residual were measured before transurethral resection of the prostate during 2 studies. Residual fraction was defined as post-void residual divided by pre-micturition bladder volume multiplied by 100 and pre-micturition bladder volume was calculated by voided volume plus post-void residual. There was a significant correlation between the difference of pre-micturition bladder volume and that of post-void residual estimated during the first and second session (r = 0.736, p <0.001) and the intra-patient variation in residual fraction had significantly less than that in measurement of post-void residual (p <0.001). Residual fractions measured during the first and second session at baseline was inversely correlated with the increase in maximum flow rate, respectively (r = -0.401, p = 0.005, for the first session and r = -0.694, p <0.001, for the second session). Residual fraction can predict obstructive and no obstructive voiding dysfunction. Furthermore, It is simpler and less invasive than pressure-flow study and more reproducible than post-void residual measurement.

This cross-sectional investigation evaluated the trend of psychological changes by Qi-training using a self-report inventory of emotional distress, Symptom Check List-90-Revision (SCL-90-R). Forty-one normal healthy subjects (mean age: 21.0±5.4) and one hundred-twenty-three Qi-trainees (divided into three groups, primary, middle and high level) participated in this study. Primary level group has received 1-4 months Qi-training (mean age: 22.0±7.8, n = 41); middle level group has 5-12 months Qi-training (mean age: 20.0±7.8, n = 41); and high level group has more than 1 year Qi-training (mean age: 22.7± 6.7, n = 41). Our results show that all of psychologucal symptom scales of Qi-trainees over lyear were significantly lower scores compared to controls. In addition, high level group had lower global indexes scores than control. A significant negative correlation was found between the Qi-training period and all SCL-90-R subscales except phobic anxiety. These results suggest that Qi-training is effective in protection as well as reduction of psychological symptomatology.

We investigated the influence of testis on the gender identity in late adolescent Korean males dwelling in a community. Of 27,202 men aged 20 years dwelling in the community, 2,700 men were randomly selected at a 10.0% sampling fraction. A total of 2,080 men who agreed to participate in the study and all volunteers underwent a standard evaluation. For the evaluation of influences of testis on the gender identity, we used the Bem Sex Role Inventory in the subjects who had testis torsion, testis injury of cryptorchidism as well as with no testicular disease. They were categorized as group 1; normal testis size, group 2; testis atrophy, and group 3; no testis in the scrotum. The median masculinity scores of group 1, 2 and 3 were not significantly different (group 1; 4.3 [3.65.0], group 2; 3.9 [3.1-4.5] and group 3; 4.6 [4.0-5.1], p=0.065). Regarding the femininity score, there were no differences among groups (group 1; 4.6 [4.0-5.1] versus group 2; 4.5 [3.9-4.8] and group 3; 4.6 [4.2-4.9], p=0.609). In group 3, the masculinity and femininity scores were not also different between of men underwent orchiectomy and did not undergo correction of cryptorchidism. We did not find the impact of testis on gender identity in our cohort. Additional research is needed to clarify the underlying psychopathology involved.

The purpose of this study was to invesgate the effect of L. japonica tumbo(P) on blood glucose level and lipid metabolism in streptozotocin(STZ) induced diabetic rats. Male Sprague-Dawley rats weighing(180~200g)were divided into four groups: control(C), STZ-control(CD), and two experimental groups(P and PD). Diabetes mellitus were induced by single injection of the streptozotocin at tue dose of 60mg/kg B.W. The experimental groups were fed a AIN-76 recomendation diet mixed with the P powder(5%/kg diet). The diet and water were intake determined everyday. The blood glucose level was determined everyweek, and the serum cholesterol was determined every two weeks. After 5 weeks, the rats sacrificed and the blood glucose, serum cholesterol. triglyceride, HDL-cholesterol concentrations were determined. LDL-cholesterol concentrations was calculated by eqation. Diabetic rats showed the lower weight gain compared to the normal rats. The serum glucose level of PD was not lower than C group. However, the serum cholesterol, triglyceride and HDL-cholesterol level of CDI and PD group were heigher than C group. Diabetic rats showed that the hepartic glutathione reductase(GR) was sighificantly heigher than C group, but malondialdehyde level was significantly decreased. P supplymentation was reduced the hepartic malondialdehyde(MDA) level. The glutathione reductase(GR) and HDL-cholestrol level were increased in the diabetic experimental groups compared C group. In comculusion, showing the possibility of preventive and therpeutic use of the wild edible plant(Indong- Cho) to the diabetes mellitus.

Purpose : This study aimed to identify the range of normal facial asymmetry using three-dimensional CT and to develop a simple method of diagnosis of facial asymmetry. Materials and Methods : Twenty eight adults with normal occlusion (16 males and 12 females; mean age 24 years and I month) were selected, whose faces were assessed to be symmetric by an orthodontist. Three-dimensional reconstructions were obtained utilizing spiral CT scans and an oral and maxillofacial radiologist, evaluated nineteen anatomic landmarks in three-dimensional coordinates. Facial asymmetry index of each landmark was caluculated. Results : The range of normal facial asymmetry of each landmark was identified using mean and standard deviation of facial asymmetry index. Conclusions : The range of normal facial asymmetry identified in this study may be used as a diagnostic standard for facial asymmetry analysis. (Korean J Oral Maxillofac Radiol 2007; 37: 45-51)
