The results of ground vegetation experiment conducted at completely denuded forestland in the mudstone region are summerized as follows: On the reaults of soiling quantity the effect of soiling was observed where depth of soiling over 10 cm was practiced, and a plot where treated with I5cm soiling and without fertilizer showed poor growth and it was even worser than the plot where soiling was practiced only 1 cm in thikness but applied adequate amount of fertilizers. The depth of slits between 30cm and 40cm showed no significant difference in the effect. A plot where covered with vegetation bag showed somewhat better results in seed loss and early growth but no differences observed in the fall result over the none covered plot. And then, it is recommendable to have soiling over 10cm in thikness with slit of 30cm and 30cm in depth and to apply 30 gram of fertilizer (22; 22:11, 50 gram) per slit. On various soiling materials trial there were no striking differences in the effect of soiling between weathered granite soil, wheathered tuffs soil and weathered mudstone soil. In the treatment with various green materials, a plot treated with straw mat showed a significant difference at 1 percent. The results show that weathered mudstone soil is effective to use as soiling materials and straw mat treatment was better. On forest fertilization trial, in the mudstone region where red and black pine trees already existing at a rate of 2,000-3,000 trees per hectare had applied 110kg of compound fertilizers (9: 12: 3 and 22: 22: 11) per hectare basis in terms of plant nutrient. As a result, the difference in effect between the compound fertilizers was not found however the leaf color and leaf length of the fertilizer added plot showed darker and longer at 30 percent over the no fertilizer received plot. Compound fertilizers, 14: 37: 12 and 9: 12: 3 were applied to alder trees at a rate of 20 gram and 40 gram per tree in terms of plant nutrient and a remarkable growth accelerantion was observed where 40 grams of plant nutrient applied. The effect difference between the compound fertilizers was not found. On investigation of tree root elongation, forty years old red pine trees showed only 15cm tap root elongation through mudstone while black pine had 23 cm tap root elongation. The total length of supporting root elongtion of red and black pines showed 20 and 13 meters, respectively. The tap. roots of Black locusts were not able to elongate through mudstone, however, the supporting roots tanded to develop to the underneath of pine tree where some moisture content is available. `Black locusts And grown on the residual soil of mudstone normally die between 8 to 10 years. The red pine trees show flat in tree shape while black pine had triangle in the shape. With the results it can be said that in an artificial reforestation in denuded forest land of the mudstone region the adequate slit and enough amount of fertiliizer application must be provided for the succesful performance of the program. On integrated experimental results of 1972. for the establishment of ground vegetation on the completely denuded forest land in mudstone region, soiling could be effectively practiced with weathered mudstone soil and it would not specially necessiate to have either weathered granite or tuffssoil for the soiling. And the soiling depth should be more than 10 em in thickness. Among green materials used the straw mat proved to be the most effective reatment. Three major factors which enable to establish ground vegetation by the shortest period of time: A. Physical improvement of soil is necessary to breakdown of the horizontal cracks sushas Slit, contour line plot, seeding hole and etc., and soiling with weathered mudstone soil. B. Chemical improvement of soil: is needed sufficient amount of fertilizer application 300∼400kg ha, N÷P₂O_5÷K₂O), and increased production of ground covering and expedite resolution of the vegetation (ground vegetation

1. Aiming at supply of basic informations on tree species siting and forest fertilization by understanding of soil properties that are demanded by each tree species through studies of forest soil`s morphological, physical and chemical properties in relation to tree growth in our country, the necessary data have been collected in the last 10 years, are quantified according to quantification theory and are analyzed in sccordnace with multi-variate analysis. 2. Test species, japanese larch (Larix leptolepis Gord) and the Korean white pine, (pinus koraiensis S et Z.) are plantable in extensive areas from mid to north in the temperate forest zone and are the two most recommended reforestation tree species in Korea. However, their respective site demands are little known and they have been in confusion or considered demanding the same site during reforestation. When the Korean white pine is planted in larch sites, it has shown relatively good growth, but, when Japanese larch is planted in Korean white pine site it can hardly said that the Japanese :arch growth is good To understand on such a difference soil factors have been studied so as to see how th soil`s morphological, physical and chemical factors affect tree gorwth helped with the electronic computer. 3. All the stands examined are man-made mature forests. From 294 Japanese Larch plots and 259 Korean white pine plots dominant trees are cut as samples and through stem analysis site index is determined. For each site index soil profiles are made in the related forest-land for analysis. Soil samples are taken from each profile horizon and forest-land productivity classification tables are worked out through physical and analyses of the soil samples for each tree species for the study of relationships between physical, chemical and the combined physical properties of soil and tree growth 4. In the study of relationships between physical properties of soil and tree growth it is found out that Japanese larch growth is influenced by the following factors in the decreasing order of weight deposit form, soil depth, soil moisture. altitude, relief. soil type, depth a A-horizon, soil consistency, content of organic matter, soil texture, bed rock, gravel content, aspect and slope. For the Korean white pine the influencing factors` order is soil type, soil consistency, bed rock, aspect, depth of A-horizon, soil moisture, altitude, relief, deposit form, soil depth, soil texture, gravel content and slope. 5. In the study of relationships between chemical properties of soil and tree growth it is found out that Japanese larch growth is influenced by the following factors in the order of base saturation, organic matter, CaO, C/N ratio, effective P₂O_5, PH, ecxhangeable, K₂O, T-N, MgO, CEC, Total Base and Na. For the Korean white pine the influencing factors` order is effective P₂O_5, Total Base, T-N, Na, C/N ratio, PH, CaO, base saturation, organic matter, exchangeable K₂O, CEC and MgO. 6. In the study of relationships between the combined physical and chemical properties of soil and tree growth it is found out that Japanese larch growth is influenced by the following factors in the order of soil depth, deposit form, soil moisture, PH, relief, soil type altitude, T-N, soil consistency, effective P₂O_5, soil texture, depth of A-horizon, Total Base, exchangeable K₂O and base saturation. For the Korean white pine the influencing factors` order is soil type, soil consistency, aspect, effective P₂O_5, depth of A-horizon, exchangeable K₂O, soil moisture, Total Base, altitude, soil depth, base saturation, relief, T-N, C/N ratio and deposit form. 7. In the multiple correlation of forest soil`s physical properties larch`s correlation coefficient for Japanese Larch is 0.9272 and for Korean white pine, 0.8996. With chemical properties larch has 0.7474 and Korean white pine has 0.7365 So, the soil`s physical properties are found out more closely related with tree growth than chemical prop

This study was conducted in order to obtain basic information for the development of a special compound fertilizer of the trials for chestnut tree cultivation in 1979-1980. Results were as follows: 1. Differences in growth performence after application of single, compound and special compound fertilizer was not significant, but fertilized showed more vigorous growth compared to control plots (without fertilizer). 2. Appearance of Chestnut strobile-drops was observed at: 62.2 % in control plots, 37-50 % in each single and compound fertilizer plots and in those with the double amount of compound fertilizer, 0.7 % in special compound fertilizer plots, 6.2 % in those with double amount of special compound fertilizer. 3. Riped strobiles were collected: 249 in compound fertilizer plots, 625 in special compound fertilizer plots, 391 in double amount of compound fertilizer plots, 816 in double amount of special compound fertilizer plots. 4. The production of chestnuts was: 4,662g in single fertilizer plots, 4,678g in compound fertilizer plots, 28,880g special compound fertilizer plots, l1,736g double amount of compound fertilizer plots, 33,073g double amount of special compound fertilizer plots. There was on significant differences of chestnut production between single fertilizer plots and compound fertilizer plot, but the production in double amount of special compound fertilizer plots was three time higher than in double amount of compound fertilizer plots. 5. The amount of chestnut production in 1980 dcereased compared to 1979 in single and compound fertilize plots due to shortage of sun light and high precipitation in the vegetation period but increased two times more in 1980 compared to 1979 in double amount of compound fertilizer and double amount of specific compound fertilizer plots. 6. Observation of these fertilizer-trial-plots will be continued during the next years in order to obtain more specific datas.

This experiment was to investigate and analyse the effect of fertilizer at different level of treatment where the ordinary chemical fertilizers (Urea, TSP, muriate of potash) and the same amount of nutrients contained solid fertilizer respectively applied. 1. Ordinary chemical fertilizer known as quick releasing fertilizer showed its main effect in the first and second years but the effect was declined in the third year wheras slow releasing solid fertilizer showed no effect in the first year but gradually appeared in second year was reached at peak in the third year and effect continued till the forth year. 2. Both treatments, ordinary chemical fertilizer and solid fertilizer, showed fertilizer effect however ordinary chemical fertilizer treatment had 6.2 per cent of fertilizer loss over the solid fertilizer treatment. 3. Optimum fertilizer dose per tree seems to be 40-80 grams and fertilizer effect was continued for three years after the treatment. Fertilizer response in the first year only appeared on leaves with dark in color and its response on growth was observed in second year where ordinary chemical fertilizer applied and solid fertilizer treatment showed in third year. 4. For the above results, it may be desirable that optimum amount of ordinary chemical fertilizer should be applied once every other or every two years and solid fertilizer should be applied once every two years or every three years. 5. Solid fertilizer does not occure fertilizer damage when it was applied in excess and has labor saving advantage. 6. It is highly recommendable to produce solid fertilizer for the forest use in view of improving forest soil fertility and increasing forest resources in Korea.

The esthetic factor for the esthetic prosthesis were studied on 300 persons. The praaticipants were 150 students registered under the Deparment of Dental Laboratoy Technology, Jisan Junior College at the present day of June, 1995 and their mothers. The results were as follows; 1. The number of persons with 28 teeth in their oralcatity was highest(P<0.01). They complained that they have only 28 teeth bacaues of the loss(deficiency) fo teeth due to their impacted teeth and dental caries. 2. The presons with feelings of dissatisfaction were large in number(P<0.01). They were dissatisfied with an abnormal tooth form(33.5%), tooth position(31.7%), tooth color(31.1%), and tooth size(3.7%) in order(P<0.01). 3. In their facial form, the most numerous were men with square form and women with ovoid form(P<0.01). Among the whloe number fo facial forms it appeared to decresae in the order of ovoied(41.8%), square(32.7%), square+tapered(20.5%), and tapered form(5%)(P<0.01). In a profile form, the most numerous were men with A form and women with B. Among the whole participants the most numerous were persons with B form and persons with A and C form were next in oder of numbers(P<0.01). 4. In discoloration of teeth, the most numerous were persons who have no discoloration. 5. In the esthetic recovery of anterior prosthesis the color matching of proximal teeth was not correct, but the outline of proximal teeth was to be reproduced correctly. 6. In the diastema of teeth, the number of persons who have no diastema was higher than that of persons who have a disatema(P<0.01) Among the persons who have diastema the most numerous were persons who have a diastema, and next were 2, 4, 3 and 5 diastemas in order. 7. In a meeting point of the midline of the body and the tooth the number of person hanving a meeting point was higher than that of persons who did not fit each other(P<0.01). The bias direction of midline teeth appeared to be affected by chewing direction, prosthesis location, and posterior location. 8. The length and width of teeth in the tooth size were suitable(P<0.01). The number of persons who have central teeth longer than lateral teeth was high(P<0.0). 9. In the results of smile analysis, the line form connected with incisal edge of upper canine were parallel(P<0.01). When smile the location fo upper lips should be in accord with the central area of teeth(P<0.01) and lower lip should be atteched to the edge of anterior teeth in order to be esthetic. 10. Among the number of upper teeth we can see the most numerous were 8 teeth and next were 10, 6 and 12 in order.

N/A Exudative ascites should initiate an evaluation for peritoneal processes, most importantly infection and tumor. And the pathological diagnosis is required for a approapriate treatment in most cases. To assess the diagnostic accuracy and complication rates of diagnostic laparoscopy in patients with exudative ascites we studied in 73 patients with exudative ascites retrospectively. Thirty three patients had malgnancy related ascites, and peritoneal carcinomatosis was confirmed in thirty one patients. Twenty seven patients had tuberculous peritonitis, and thirteen patients had miscellaneous causes, among them eight patients had underlying liver cirrhosis and clinically spontaneous bacterial peritonitis were suspected in three patients in whom bacteria were cultivated in ascites. Pancreatic pseudocyst and leakage into peritoneal cavity was confirmed by endoscopic retrograde pancreatography in one case, but the remained four cases had not known the diagnosis. The most common primary cancer was gastric carcinoma which was diagnosed in fourteen patients, and then ovarian cancer in five patients, colon cancer in four patients, pancreatic cancer in three patients, mesothelioma in one patient and unknown origin in four patients. Cytology evaluation of the ascitic fluid was positive for tumor cells in 62% of patients with peritoneal carcinomatosis. Blind Cope needle biopsy yielded positive diagnosis of neoplastic or tuberculous in 65.4 per cent of rases. The major and minor complication rates of laparoscopy were 0% and 26.4%, respectively, with no fatalities. These findings compare favorably with general experience. We conclude that laparascopy is relatively safe and accurate diagnostic method of choice in exudative ascites, especially in cases when other non-invasive methods were failed.

N/A The lack of an effective drug against chronic type B virus infection has led to trials of variety of antiviral drugs. Among these drugs interferon has shown more encouraging results. In all studies, greater HBeAg to anti-HBe seroconversion rates occurred in treated patients than in control. The reason for the use of interferon in this disease is the effectiveness as an antiviral activity. More recently its activity has heen extended as an immunomodulating drug in the immune response. The purpose of this study was to elucidate the effect of human fibroblast interferon (β-interferon) in Korean HBsAg positive chronic active hepatitis. We has conducted therapeutic trial with total l02 X1000000 IU of beta-interferon for 28 days in fifteen cases with needle aspiration biopsy proven chronic activc heaptitis. 1) Six patients (40.0%) lost HBeAg in the serum and four of these patients (26.7%) were seroconverted to anti-HBe after β-interferon therapy. And two patients expressed anti-HBe without loss of HBeAg. However, none of the patients lost HBsAg during the study peroid. 2) The serun ALT began to increased significantly (p<0.05) from the 7th day of interferon therapy and reached its maxinauin level on 10th day of therapy, and then continued to decrease to the level below the pretreatment level in 2nd week after treatment of interferon. 3) Pre-tretament ALT showed higher levels in group of changed viral rnarkers (n=6) than in unchanged (n=8), but there was no statistical significance. 4) Peripheral blood leukocytes and granulocytes showed significant reduction in number from the 3rd day of interferon treatment (p<0.05), and recovered within one week after withdrawal, 5) There was no significant changes in serum protein, bilirubin and prothrombin time. 6) All the treated patients experienced an initial flu-like illness consisting of fever, chills, malaise, myalgia, anorexia, headache and dizzeness. Tachyphylaxis developed gradually during the treatment. The above results suggest that β-interferon therapy may be effective and safe in the treatment of patients ivith tvpe B chronic activc hepatitis.

N/A Background/Aims: Helicobacter pylori has been shown to be an important pathogen of gastric disorder including gastritis and gastric ulcer. One of the potential toxic factors involving gastric mucosal cell injury is reactive oxidants, which are released from activated neutrophils. Rebamipide had been reported to promote mucus synthesis, mucosal prostaglandin content, and rapid ulcer healing, It has recently been reported to inhibit the production of oxygen derived free radicals from stimulated neutrophils. We conducted this study to evaluate the effects of rebamipide on gastric ulcer healing and reactive oxygen metabolite production. Methods: In this multicenter study conducted in Korea, combination treatment of rebamipide and ranitidine was compared with ranitidine alone in 108 patients with gastric ulcer patients. Pre- and post-treatment endoscopic findings and concentration of reactive oxygen metabolite produced were used to evaluate efficacy. The efficacy of rebamipide and ranitidine versus ranitidine was evaluated using endoscopy results, and tissue lipid peroxides by thiobarbituric acid and myeloperoxide concentration. Results: The percentage of ulcer size reduction was significantly higher with rebamipide and ranitidine group than with placebo and ranitidine group(size reduction: 71.5% vs 58.3% P=0.04556). The myeloperoxidase activities at ulcer margin in rebamipide and ranitidine group patients were 96.7+-13.4 unit/mg protein in baseline and 53.8+9.9 unit/mg protein in follow up (P=0.0065). The myeloperoxidase activities at ulcer margin in placebo and ranitidine group patients were 90.2+9.1 unit/mg protein in baseline and 63.1+6.7 unit/mg protein in follow up (P=0.0668). The thiobarbituric acid activities at ulcer margin in rebamipide and ranitidine group patients were 34.7+5.3 nmol of MDA/mg protein in baseline and 24.1W3.1 nmol of MDA/mg protein in follow up. The thiobarbituric acid activities at ulcer margin in placebo and ranitidine group patients were 14.8+1.5 nmol of MDA/mg protein in baseline and 24.3+2.7 nmol of MDA/mg protein in follow up (P=0.0059). The thiobarbituric acid activities at ulcer margin in H. pylori positive and negative patients were 28.1+2.1 nmol of MDA/mg protein and 25.3+4.7 nmol of MDA/mg protein, respectively. The myeloperoxidase activities at ulcer margin in H. pylori positive and negative patients were 79.9+5.3 unit/mg protein and 40.4+25.3 unit/mg protein, respectively (P=0.0001). The cumulative relapse rate was examined starting at 24 week after ulcer treatment. The rate was lower in rebamipide and ranitidine group patients, but insignificantly(19.2% vs 27.3%, P=0.0857). Conclusions: These results suggest that rebamipide promote gastric ulcer healing by decreasing reactive oxygen metabolite production in patients with gastric ulcer.

N/A Objectives: The exact causes of nonspecific chronic laryngitis or laryngeal symptoms are unknown, but many cases of this disease are associated with gastroesophageal reflux or motility disorders of esophagus. We suppose that because Korean people have less gastroesaphageal reflux diseases and the life style including food is different from those of western people, the causes of chronic laryngeal symptoms nre different, So we studied the patients who complained the chronic laryngeal symptoms for evaluation of the role of esophageal motility disorders and gastroesophageal reflux. Methods: 19 patients(male 3, female 16, mean age 40(26-66)) with hoarseness, globus sensation, sorethroat of chronic nature(greater than 3-month duration), not response to conventional therapy of otolaryngologist in St. Mary's Hospital were referred to department of internal medicine. A group of normal, 15 healthy subjects(male 7, female 8, mean age39(24-57)) who had no esophageal or laryngeal symptoms was studied as a control group. All patients and normal controls had manometric studies and 24 hour ambulatory pH monitoring. abnormal findings required pathologic reflux or results greater than the mean plus 2 SDs of normal controls. Results: 1) The chronic laryngeal symptoms were hoarseness in 15 patients(79%), globus sensation in 14 patients(74%), sorethroat in 6 patients(32%), pulmonary symptoms in 3 patients(16%), dysphagia in 2 patients(11%) and heartburn in 1 patient(5%). 2) The lower esophageal sphincter pressure by the rapid pull through tecnique(mean±SD, 27,9± 6.9mmHg) in patients was not different compared with normal controls(31,1±11.0nmHg), 3 patients (16%) had esophageal body dysmotility and all of these were non specific motility disorder. 3) The upper esophageal sphincter pressure(mean±SD, 53.2±23.8mmHg) in patients was not different compared with normal controls(40.9±20.8mmHg), but 2 patients(10.5%) had high upper esophageal sphincter pressures(>82,5mmHg), The postrelaxation pressure of upper esophageal sphincter(mean±SD,98.3±32.1mmHg) was not different compared with normal controls(79,8±30.6mmHg), but 2 patients(10.5%) had high postrelaxation pressures of upper esophageal sphincter(>141mmHg). 4) The time(mean±SD, 321±193msec) between lowest point of upper esophageal sphincter relaxation and onset of pharyngeal contraction was not different compared with normal controls(273.5±179,8msec). 5) The percentage of time of pH less than 4 was 2.4±4.7% in total periods, 2.5±2.3% in upright position and 2.4±9.7% in supine position. Two patients (10.5%) had pathologic reflux(more than 4% of percentage of time pH less than 4 in total periods) and one patient with 2.5% of persentage of time pH less than 4 had high symptom index(66.7%(4/6)). 6) According to above results either of abnormal esophageal pressure or dysmotility was seen in 6 patients(32%) and either of more than 4% of persentage time pH less than 4 in total periods or positive symptom index was seen in 3 patients(16%), Positive results in either of two tests were seen in 7 patients(37%). Conclusion We suggest that some patients who complain the chronic laryngeal symptoms in Korean may have abnormal esophageal motility or gastroesophageal reflux.

Appreciable radiation exposures certainly occur in the workers who handle radioiodine in biochemical research, nuclear medicine diagnostics with the development of nuclear industries. But in the case of occurring the nuclear accidents, the early medical treatment of radiation injury should be necessary but little was reported in korea till now. Accordingly, to achieve of the basic data for protective roles and medical treatment of radiation injury, the present studies were carried out to evaluate the decontamination of radioiodine by the administration of the antithyroid drugs. The results observed are summarized as follows: 1. The administration of sodium iodide and potassium iodide results in rapid excretion of radioiodine and reduction of the whole body retention than the saline-only group. 2. Reguarding to thyroid protective effects, sodium iodide, potassium iodide and saline were effected significant in order. 3. In the control(saline) group, if administered with enough fluids, the whole body retention of radioiodine is reduced temporary shifts. But as far as radioprotective effects is concerned, saline was not more in the protective effects than the other groups. In conclusion, in case of nuclear accidents, if being administered sodium iodide and saline as quickly as possible, the radioprotective effects against the radiation hazard might be markedly increased in the internal contamination of radioiodine.
