We evaluated the efficacy of the liquid form of enrofloxacin against poultry respiratory and digestive infections, the major problems in the poultry industry, from diverse diagnosis viewpoints. Results obtained through this study were as follows: 1. The liquid form of enrofloxacin showed good acceptability to poultry owing to no abhorrence to the drug by chickens, which indicated its suitability for mixing in drinking water. 2. The application of the enrofloxacin formulation improved the productivity of the chicken farm to a great extent by lowering the death toll of chicken raised in the farm. 3. The use of the drug shortened the days to the market, and increased the body weight at the time of marketing. 4. Preventive and therapeutic effects of the liquid enrofloxacin were observed higher than ampicillin, a major antibiotic used in poultry farming. From above results, the liquid form of enrofloxacin would find its use for the prevention and treatment of digestive and respiratory infections, let alone the growth promotion and feed efficiency, especially in the chicken farming practice.

Chronic recurrent dislocation(CRD) of the jaw has various etilogical causes, including trauma, congenital or acquired neurological illness, ingestion of certain medicines, incorrdination of the neuromuscular astivity of the chewing muscles, articular anatomical alteration, etc. Various surgical methods have been advocated for the treatment of the CRD. They may be divided into two groups: procedures designed to limit translation of the condyle and procedures eliminating obstacles in the condylar path. Hypomobility of mandible can be developed after BSSRO and it is probably caused by scar contracture, atrophy, and myofibrosis. Many authors, therefore, emphasized the importance of physical therapy especially after BSSRO to prevent the complication. Based on that idea, we designed more conservative surgical method to limit mandibular openning compared the methods that previously introduced and tried to treat the CRD. This new method consists of extensive subperiosteal dissection of masseter and the temporalis muscle under local anesthesia and use of intermaxillary elastics for some periods.

To compare the effect of hyaluronate and dexamethasone on the temporomandibular joint arthrocentesis the author investigated 22 temporomandibular joint disorder(TMD) patients with pain and limitation of mouth opening who visited at the Department of Oral and Maxillofacial Surgery. Chosun Dental Hospital and were made a diagnosis as Wilkes stage Ⅲ or Ⅳ of TMJ internal derangement clinically and radiographically. The two groups consisted of 10 patients with injection of sodium hyaluronte 10mg(Artz)(hyaluronate group) on the upper joint space of the affected temporomandibular joint 5 times at intervals of a week after arthrocentesis, and 12 patients with injection of dexamethasone(Oradexon) at a time(dexamethasone group). Maximum mouth opening, pain value and satisfaction value during mastication were assessed on a visual analog scale before arthrocentesis and after 6 months. Then the within-group and between-group differences were evaluated in the obtained data and the clinical success rate of each group was calculated according to our success criteria. The results were as follows. 1. the mean of maximum mouth opening before arthrocentesis and after 6 months in the hyaluronate group were 24.9mm and 39.0mm respectively, and those before arthrocentesis and after 6 months in the dexamethasone group were 25.7mm and 41.3mm respectively. 2. The mean of pain value on a visual analog scale in the hyaluronate group before arthrocentesis and after 6 months were 6.7 and 1.8 respectively, and those in the dexamethasone group before arthrocentesis and after 6 months were 7.0 and 1.8 respectively. 3. The mean of satisfaction value during mastication on a visual analog scale in the hyaluronate group before arthrocentesis and after 6 months were 2.8 and 7.7 respectively, and those in the dexamethasone group before arthrocentesis and after 6 months were 3.1 and 7.8 respectively. 4. There were statistically significant differences between all meansurements before arthrocentesis and after 6 months(P<0.001), but no difference between all meansurements in the hyaluronate group and those in the dexamethasone group. 5. The over all success rate of the hyaluronate group and the dexamethasone group were 60.0% and 63.6% respectively. In summary, there was significant difference between the effect of hyaluronate and dexamethasone on the temporomandibular joint arthrocentesis but hyaluronate is better than corticosteroid as the injection drug in consideration of the side effect related with repeated injection.

Objective : For the purpose of preparing the fundamental data and assessing the status of exposure level of chemical substances and physical agents. Methods and Material : Such as noise, two types of dust, four types of metals, seventeen types of organic solvents, and four types of other materials classified by specific chemical substances in 21 metal product plating factories classified by 28 processes. The author determined exposure level on those hazardous materials from Jan. to Dec. 2001. Results : The results were as follows: 1. The exposure level for noise was exceeded to Threshold Limit Value(TLV) in the process of 6 cases of Machining, 5 and 4 cases of pre and post-buffing, and 6 cases of waterdrop-removing, the mean noise level of all of processes was not exceeded to compliance level. 2. The exposure level for dust was not exceeded to TLV at all. 3. The exposure level for Chromium(Cr) was exceeded to TLV in Chromium plating process, metal exposure level including Zinc(Zn), Manganese(Mn), and Lead(Pb) was not exceeded to TLV. 4. The exposure level of toluene in case of organic solvents was exceeded to TLV in 1 case of finishing/cleaning, coating/developing process, respectively. 5. The exposure level of four types of other materials classified by specific chemical substances were not exceeded to TLV. 6. The exposure level for dust and metal including Zn, Mn, and Pb was decreased in comparison with two results of air monitoring performed. There was no difference of the exposure level for Cr, noise, and four types of other materials classified by specific chemical substances, and the exposure level for organic solvents was slightly increased. 7. The exposure level for noise in factories employing more than 21 workers was higher than that for noise in foadtories employing less than 20 workers. The more workers, the lower exposure level in metal including Zn, Mn. The exposure level for Cr was increasing in factories employing more than 51 workers, and the more workers the lower exposure level in organic solvents. Conclusion : According to above results, this study suggests positive work environment managements in processes exceeding exposure limit value as well as continuously consecutive work environment management in processes not exceeding exposure limit value and revealing no chronological difference of exposure level should be needed.

韓藥材 중 肺炎의 치료효과가 기대되는 淸熱化痰, 止咳平喘藥을 중심으로 23種의 藥材를 사용하여 肺炎을 유발하는 K. pneumoniae, S. pyogenes 및 S. pneumoniae 세균의 생육을 억제하는 藥材를 탐색하고, 탐색된 藥材의 추출물에 대한 세균의 最小生育抑制濃度를 측정하였다. 韓藥材의 水溶性 추출물 중 黃連, 胡黃蓮, 敗醬, 黃芩이 K. pneumoniae에서, 黃連이 S. pyogenes에 대해서 생육억제 효과가 있었으며, S. pneumoniae에 대한 比較沮止環의 直徑은 黃連, 鳥梅, 五味子, 黃芩이 우수하였으나 黃連 추출물 사용시 병원균 모두에서 生育沮止環의 크기가 가장 크게 나타났으며 對照群로 사용된 大腸菌과 枯草菌에서도 어느 정도의 抗細菌 효과를 볼 수 있었다. 에탄올 추출물에서는 敗醬, 黃芩, 五味子, 鳥梅가 K. pneumoniae 세균의 생육을 억제하였으며, S. pyogenes 세균은 黃連, 五味子, 鳥梅, 馬兜鈴찾, 黃芩에 의하여 생육이 억제되어 黃連은 水溶性 및 에탄올 溶解性 주출물에서 모두 우수한 抗細菌 효과를 보여주고 있다. 각 세균에 대한 最小生育沮止濃度(MIC)는 K. pneumoniae 세균일 경우 黃連 및 黃芩의 水溶性 추출물과 鳥梅 및 敗醬의 에탄올 溶解性 추출물이 유의성을 보였으며, S. pyogenes 세균은 黃連의 水溶性 및 에탄올 溶解性 추출물과 鳥梅의 에탄올 溶解性 추출물, S. pneumoniae 세균은 黃連과 鳥梅의 水溶性 및 에탄올 溶解性 주출물에서 유의성이 나타났다. 이상의 결과를 통하여 黃連, 五味子, 鳥梅, 黃芩, 胡黃蓮, 敗醬의 水溶性 및 에탄올 溶解性 추출물이 肺炎 誘發菌f K. pneumoniae, S. pyogenes, S. pneumoniae에 對하여 우수한 生育抑制 作用을 나타냄을 알 수 있었다. The various oriental herbal medicines, which have usually been used for treatment of reducing fever, purging intense heat and detoxication, were screened to determine the antibacterial activity and the minimal inhibitory concentration against pulmonary disease-causing Klebsiella pneumoniae, Streptococcus pyogenes, and Streptococcus pneumoniae. The results obtained were as follows: 1. Among the 23 oriental medicines tested, the water-soluble extracts of Coptis japonica, Scutellaria baicalensis and Picrorrhiza kurroca showed the antibacterial activity against K. pneumoniae and that of C. japonica against S. pyogenes. The antibacterial activities of C. japonica, Prunus mume, Schizandra chinesis, Scutellaria baicalensis were also found against S. pyogenes. When C. japonica was used, the high antibacterial activity was shown against Bacillus subtilis and other extracts showed a little activity against B. subtilis and E. coli as a control. 2. The ethanol-soluble extracts of Patrinia scabriosaefolia, P. mume, S. baicalensis, S. chinensis showed the antibacterial activity against K. pneumoniae and those of S. baicalensis, C. japonica, S. chinensis P. mume against S. pyogenes and S. pneumoniae. However, those extract showed a little antibacterial activity against B. subttilis and E. coli except for that the extract of C. japonica showed comparatively high growth inhibition of B. subtilis. 3. Among the medicinal herbs tested, the water- and ethanol extracts of C. japonica showed very extcellent antibacterial activity against the pathogenic bacteria and controls. 4. When the water-soluble extracts of C. japonica and S. baicalensis, minimal inhibitory concentrations (MICs) against K. pneumoniae were 10 ㎎/㎖ and 22 ㎎/㎖, respectively. The MICs of the ethanol-soluble extracts of P. mume and P. scabriosaefolia were 5 ㎎/㎖ and 20 ㎎/㎖, respectively. 5. For the MICs against S. pyogenes, C. japonica showed 15 ㎎/㎖ with the water-soluble extract and P. mume and C. japonica with the ethanol-souble extract did 5 ㎎/㎖ and 10 ㎎/㎖, respecitively. 6. For the MICs against S. pneumoniae, C. japonica and P. mume with the water- and ethanol-souble extract showed 5 ㎎/㎖ and 10 ㎎/㎖, respecitively. As a result, the highest antibacterial activity was found in the water- and ethanol-soluble extracts of C. Japonica against pulmonary disease-causing bacteria, K. pneumoniae, S. pyogenes, and S. pneumoniae. Also, the water- and ethanol-soluble extracts of S, chinensis, P. mume, S. baicalensis and P. kurrooa showed high antibacterial activities.

A study on the wate pollution of Kwangju stream by the relationship between physical-chemical condition and indicator planktons distribution by water quality level was examined at 6 sampling positions during the period from Mar, 25 to Jun, 25 1984. The results were as follows; 1. pH was in the range of 6.3∼7.6. 2. The mid-stream of Kwangju stream was the more severly polluted than the other sampling positions and the average range for it was 0.3∼3.9 ppm of DO, 62∼352 ppm of BOD, 5.3∼24 ppm of T-N and 2.3∼140 ppm of T-P. 3. The plankton identification in this period showed 5 genera 6 species of Cyanophycea, 11 genera 15 species of Bacillariophyceae, 9 genera 16 species of Chlorophyceae and 6 genera 7 species of protozoa: total 31 genera 44 species. 4. In biological water analysis, upper stream(sp. 1) showed from Oligosaprobic to β-mesosaprobic but the stream in the mid-town area polysaprobic. 5. In the mid-stream (BOD 62~352 ppm) dominant species were appeared Oscillatoria tennis of Cyanophyceae and Paramecium caudatum and Euglena sp. of Protozoa. 6. We would like to propose establishing sewage plants near to the upper-stream and the down-stream of Kwangju stream.
