Determination of Limiting Nutrient for Algal Growth by Algal Bioassay. Oh, Hee-Mock, Seog June Lee, Seong-Bin Kim, Mi- Kyung Park, Byung-Dae Yoon and Do-Han Kim (Environmental Microbiology Research Unit, Korea Research Institute of Bioscience and Biotechnology, Taejon 305-333, Korea and Water Resources Research Institute, Korea Water Resources Corporation, Taejon 305-390, Korea) Water quaiity and algal growth potential (AGP) using Microcystis aeruginosa were investigated from April to September 1997 in Daechung Reservoir. Secchi disk transparency was 1.1 m in August. Chlorophyll-a concentrations were higher than 10㎍/l at all samples. Total phosphorus concentration was in a range of 0.020∼0.027mg/l which is at the approximate value of 0.03 mg/l, the general critical level of eutrophication. These results indicate that Daechung Reservoir is in an eutrophic state except some temporary times and restricted sites. Phosphorus uptake rate of M. aeruginosa was higher in the water from the epilimnion than in the hypolimnion and also higher under light condition than under dark condition. Therefore, phosphorus uptake rate appears to depend on cellular phosphorous content and light condition, a meaning of endergonic process. Phosphorus was the most frequently limiting nutrient: phosphorus was limiting algal gowth in April and May, nitrogen, phosphorus and trace elements were the limiting factors for algae in August, and trace elements in September. If a fast growing alga, M, aeruginosa, is used as a test organism for assaying AGP, in vivo fluorescence instead of dry weight can be measured for algal biomass and incubation period can be reduced from traditional 14 days to 7 days.

최근 흡연을 시작한 젊은 성언에서 급성 호산구성 폐렴의 발생에 대한 증례가 보고되고 있다. 급성 호산구성 폐렴은 대개 발열을 동반하기 때문에 초기에는 감염성 폐렴으로 잘못 진단, 치료되는 경우가 많다. 아직 정확한 병태 생리 및 조직학적 소견은 밝혀져 있지 않지만 병력 청취 및 임상 양상, 방사선 소견의 관찰을 통해 급성 호산구성 폐렴을 의심하고, 진단을 위해 기관지 폐포 세척액 검사를 시행한다면 좀 더 쉽게 진단 내릴 수 있을 것이다. 본 저자들은 최근 처음 시작한 흡연에 의해 발생한 급성 호산구성 폐렴을 진단하고, 스테로이드를 투여하여 성공적으로 치료한 환자 2예를 경험하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Acute eosinophilic pneumonia(AEP) is characterized by acute febrile respiratory illness associated with diffuse pulmonary infiltration and pulmonary eosinophilia. The specific etiology for acute eosinophilic pneumonia is elusive. By some investigators, cigarette smoking is suggested as a causative substance which can cause AEP. In recent, the authors experienced two cases of AEP following cigarette smoking. Both cases had characteristic features including age around 20 years, new onset smoking before occurance of AEP, diffuse infiltration on chest radiography, pulmonary eosinophilia based on bronchoalveolar lavage and acute improvement after steroid therapy. These clinical features are resemble with previous smoking induced AEP case reports. Base on these clinical features, cigarette smoking associated AEP could be diagnosed more easily.

The present study aims to explore the effects of applying spheroid-combined stimulating therapy on body composition. For this aim. 20 persons were selected as subjects and 10 of them each were assigned to the experimental group and control group, respectively. The experimental group was applied a 12-week combined stimulating therapy and changes in physical constitution of the members were measured before application and 4, 8 and 12 weeks after application. From the study, following conclusions could be drawn: First, body weights of the experimental group decreased from 59.9kgs before application of the spheroid-combined stimulating therapy to 57.2kgs 12 weeks after application, no significant but 4.51% change. Second, body fats of the experimental group changed from 18.8kgs before application to 16.4kgs 12 weeks after application, no significant but 12.77% reduction. Third, % fats of the experimental group decreased from 31.2% before application to 28.6% 12 weeks after application, no significant change but 8.33% reduction. Fourth, body mass index(BMI) of the experimental group decreased from 23.23 kg/㎡ before application of the therapy to 21.43kg/㎡ after application, no significant but 8.03% reduction. As seen above, the 12-week application of the spheroid-combined stimulating therapy produced no significant changes in physical constitution as physical exercise did, but improved physical constitution by reducing certain amount of boy weight, body fat, % fat and BMI. In order to detect more positive and significant changes in physical constitutions, continued studies and clinical experiments should be performed to more diverse subjects using technically reinforced equipment for spheroid-combined stimulating therapy.

Painful stiffness of the shoulder is an ill-defined clinical entity that is difficult to assess and delicate to treat. The nomenclature used is broad and includes terms such as frozen shoulder, adhesive capsulitis, focal algodystrophy, stiff shoulder, contracted shoulder, and others. Apart from its idiopathic form, the disease can be initiated by trauma, infection, tumour, radiation, systemic and local metabolic disturbances. Pathoanatomically, the common denominator is an inflammatory vascular proliferation followed by thickening, scarring, and retraction of the joint capsule. The inflammatory process often starts at the rotator interval and may extend to the subacromial space. Clinical diagnosis is based on history and physical examination. Generally the onset of pain precedes the perception of a reduced range of motion by weeks or months. In early stages of the disease, the inflammatory type of pain dominates, i.e., the patient's main complaint ist pain at night. In the later stage, range of motion gradually decreases. Patients do not often complain about reduced motion, probably because of its slow onset. The purpose of this study is to find out the effectiveness of the massage applied to the patients with Frozen Shoulder by measuring, assessing and analyzing the changes in intensity and unpleasantness of pain and range of motion(ROM) before and after massage. Surveyed from Jan. 2001 to December 2002 were 104 patients suffering from Frozen Shoulder. In the therapeutic massage program, such methods as Effleurage, Petrissage and Deep transverse friction were selected as they are among traditional massage treatments frequently used for joints with pain and restricted ROM. Effleurage and Petrissage were applied for 20 minutes in total before and after Deep Transverse Friction. After massage program, the intensity and unpleasantness of pain were measured and analyzed by means of VAS(visual analogue scale)-I and VAS-U, while ROM was measured and analyzed by using Goniometer. The major findings from this study are as follows; 1. The surveyed patients range from 28 to 75 in age, with highest numbers of 44(42.31%) registered in the fifties and next ones of 24(23.08%) in the forties. Divided by sex, 59 are women and 45 are men totalling 104 with average age of 51.4. 2. There was significant decrease in the intensity of pain and unpleasantness of pain after massage(p<.05). 3. There appeared, however, significant increase in ROM after massage(p<.05). 4. From the analysis into chronological changes in ROM before and after massage with ANOVA, it became evident that the longer the period of treatment was, the higher the ROM increases drastically, while significant difference was shown in Abduction and in External and Internal Rotation(p<.05). Summed up, it can be generally concluded that massage is an effective treatment to rid the patients with Frozen Shoulder of pains safely and promptly. This study was conducted to determine more accurate impact of massage. From the above outcomes, it was revealed that massage has proven to reduce the pains, exercising huge influence to increase ROM. It is, therefore, suggested to continue and expand the study on the cure of Frozen Shoulder and to motivate patients, orthopedists, physiatrists, physiotherapists, and sports massagists etc. to consider massage as safest and most efficient pain remedy.
