Effects of Rhizosphere Microorganisms and Wood Vinegar Mixtures on Rice Growth and Soil Properties
정강욱,김보성,Venecio U. Ultra, Jr.,이상철 한국작물학회 2015 Korean journal of crop science Vol.60 No.3
Environment-friendly growth enhancers for rice are being promoted to reverse the negative impact of intensive chemical-based and conventional rice farming on yield sustainability and environmental problems. Several rhizosphere microorganisms and pyroligneous acids (PA) had demonstrated beneficial influence on growth, yield and grain quality of rice. Since most of the previous study had evaluated the effect of PGPR and PA on paddy rice singly, the effect of combined application of these on the growth and yield of paddy rice and on some soil chemical properties were determined. A four factorial pot experiment was conducted to evaluate the effect of PGPR, PA in combination with fertilizers and on different soil types. There were 54 treatment combinations including the control with three replications under complete randomized design. Plant growth parameters were evaluated using standard procedures during tillering and heading stages. Rice yield and some soil chemical properties were determined at harvest. Results showed that inoculation of Bacillus licheniformis and Fusarium fujikuroi enhanced plant growth by increasing the plant height which could be ascribe to its ability to promote IAA and GA production in plants. Inoculation of Rhizobium phaseoli enhanced chlorophyll content indicative to its ability to improve the N nutrition. However, these plant growth benefits during the vegetative stage were override by the fertilizer application effect especially during the maturity stage and grain yield. High fertilization rates on coarse-textured soil without nutrient loss resulted to high available nutrients and consequently high yield. Wood vinegar application however improved nutrient availability in soil which could be beneficial for improving soil quality. Further evaluation is necessary to fully assess the potential benefits that could be derived from inoculation of these organisms and wood vinegar application in different soil environment especially under different field conditions.

Background/Aims: Oral sodium phosphate has been shown to be effective and safe but causes intravascular volume contraction, changes in serum calcium and phopshate level, and sleep disturbance when given two doses every 12 hours. Because the evening dose is inconvenient for many patients, we gave single morning dose, and compared it with conventional 12-hour-split dose. Methods: Sixty one patients drank 90 mL of sodium phosphate at 7:00 AM and 58 patients drank 45 mL of sodium phosphate at 7:00 PM and 7:00 AM respectively. Results: There was no statistical difference in bowel cleansing between two groups (p=0.871). There was no significant difference in patient's tolerance and symptoms between two groups except sleep deprivation which was more frequent in the split dose group. None of the patients complained of postural dizziness or presyncope in both groups. Serum phosphate levels were increased and serum calcium levels were decreased after preparation in both groups, but patients showed no significant clinical symptoms such as tetany. Conclusion: This study suggests that giving a single morning dose of sodium phosphate is effective, well tolerated and safe in most patients for precolonoscopic cleansing, compared to conventional split dose of 12-hour interval. (Korean J Gastrointest Endosc 2003;27:515-520) 목적: 본 연구는 경구용 인산나트륨으로 대장내시경 전처치 시 검사 당일 아침에 한 번 전량을 복용했을 때의 대장의 청결도, 환자가 느끼는 불편감, 안정성을 전통적 방법인 두 번 나누어 복용했을 때와의 비교를 통해 조사하였다. 대상 및 방법: 본원에서 대장내시경 검사를 받은 119명의 외래 환자를 대상으로 하였는데, 제외 대상은 신부전증, 울혈성 심부전증, 복수, 6개월 이내의 심근경색증, 장 폐쇄가 동반된 환자였다. 일 회 복용군은 61명으로 검사 당일 아침 7시에 인산나트륨 90 cc를 마시게 하였고, 분할 복용군은 58명으로 검사 전날 저녁 7시에 45 cc, 검사 당일 아침 7시에 45 cc를 마시게 하였다. 대장의 청결도를 4단계(excellent, good, fair, poor)로 구분하였고, 마시기 힘든 정도를 마신 양을 기준으로 1 (all), 2 (most), 3 (half), 4 (less than half)로 평가하였고 환자가 느끼는 증상을 0 (none), 1 (mild), 2 (moderate), 3 (severe), 4 (poor)로 구분하여 평균 점수로 평가하였다. 안정성은 검사 직전 체위성 혈압 및 맥박 변화와 전처치 전후의 혈청 칼슘치와 인산치의 변화를 관찰하였다. 결과: 무작위 배정에 의해 나눈 두 군 간의 환자의 특성은 차이가 없었다. 대장의 청결도를 4단계(excellent, good, fair, poor)로 구분하여 일 회 복용군에서는 각각 23명(37.7%), 23명(37.7%), 13명(21.3%), 2명(3.3%)이었고 분할 복용군은 20명(34.5%), 26명(44.8%), 10명(17.2%), 2명(3.4%)으로 두 군 간의 유의한 차이가 없었다(p=0.871). 환자의 순응도에 있어서도 마시기 힘든 정도나 전처치로 인해 생긴 증상은 양 군 모두 경미하며 유의한 차이가 없었고(p=0.231), 분할 복용군에서 수면장애를 호소한 환자가 25명(43.1%)으로 일 회 복용군 6명(9.8%)보다 많았으며, 37.9%가 아침에만 마시기를 희망하였다. 체위성 수축기혈압과 맥박 변화는 평균치로 볼 때 일 회 복용군 +4 mmHg, +1.9/min, 분할 복용군 +3 mmHg, +2.9/min였고 혈청 칼슘치와 인산치의 전처치 전후의 변화는 평균치로 볼 때 일 회 복용군 -0.2 mg/dL, +3.4 mg/dL, 분할 복용군 -0.4 mg/dL, +2.4 mg/dL이었으며 양 군 모두 체위성 현훈증이나 저칼슘혈증으로 인한 임상적 증상을 호소한 사람은 없었다. 결론: 경구용 인산나트륨으로 대장내시경 전처치 시 전통적인 12시간 간격의 분할 복용 대신 검사 당일 아침에 한 번에 마셔도 효과적이고 편리하고 안전하게 전처치가 이루어짐을 알 수 있었다.

Comparison of Contact Lens Corrected Quality of Vision and Life of Keratoconus and Myopic Patients
이성훈,정강욱,이형근 대한안과학회 2017 Korean Journal of Ophthalmology Vol.31 No.6
Purpose: To compare and analyze changes in vision quality, subjective symptoms, and psycho-social satisfactionin keratoconus and myopic patients following the wearing of contact lenses. Methods: This study enrolled 25 keratoconus and 25 myopic patients with corrected vision over 0.8 accordingto the Snellen chart due to treatment with contact lenses. Patients were surveyed prior to the wearing ofcontact lenses, and again after three months of contact lens usage with a questionnaire about quality of visionand life. The changes in visual function, visual symptoms, and psycho-social well-being before and aftercontact lens usage were analyzed. Results: The keratoconus patients’ overall degree of satisfaction was higher than the overall degree of satisfactionof myopic patients, and the motivation for contact lens usage and purpose of contact lens treatmentwere different in the two groups. Keratoconus patients experienced greater changes in satisfaction, particularlyin satisfaction during night activities, short-distance work, and the reading of fine print. Furthermore,they experienced fewer dry eye symptoms but greater foreign body sensations than patients with myopiafollowing treatment with contact lenses. No statistically significant differences in social role functions existedbetween the two groups. Keratoconus patients had a lower expectation of visual acuity recovery beforetreatment with contact lenses (Mann-Whitney U-test, p = 0.049) compared to myopic patients, and moreanxiety about vision loss following treatment (Wilcoxon signed-rank test, p = 0.018) compared to their levelof anxiety about vision loss before treatment with contact lenses. Conclusions: Although the same treatment was applied, keratoconus and myopic patients experienced differenttypes of discomfort and areas of improvement in contact lens corrected vision. Therefore, not only correctedvision, but also subsequent improvement and discomfort outcomes should be considered by patientswhen choosing contact lens treatment. For patients with mild keratoconus, contact lens treatment may bean efficacious first treatment modality.
