This study was using 15 fungicides for the result of control of ivy stem rot. Dipping method was better than spraying method in pot experiment. Among fungicides tested, mandipropamid SC, cymoxanil+ethaboxam WP and ethaboxam+famoxadone WP suppressed mycelial growth of Phytophthora cinnamomi. mandipropamid SC and metalaxyl+copper oxychloride(Cu) WP effectively inhibited mycelial growth of P. nicotianae. 4 fungicides were shown strong antifungal activity against the pathogens. Especially mandipropamid SC was good at control efficient of stem rot caused by P. cinnamomi and P. nicotianae.

Ten bacteria were isolated from ivy root to control ivy stem rot. In the plate test, JA508 was shown the strongest antifungal activity against Phytophthora cinnamomi and P. nicotianae, causal agents of Ivy stem rot. Control efficiencies were shown 66% for P. cinnamomi and 58% for P. nicotianae, when JA508 treated only. When JA508 and mandipropamid SC were treated alternately, control efficiencies were shown 92% for P. cinnamomi and 58% for P. nicotianae. JA508 was identified as Bacillus subtilis based on its cultural, morphological, biochemical characterization and 16S rDNA sequence analysis.

N/A Acid and pepsin are necessary for gastric digestion of protein. The gastric peptic cells are the major source of pepsinogen, the precursor of pepsin, in blood and urine, but it is uncertain whether they enter the circulation through endocrine secretion or release from degenerating cells. Pepsinogen is also found in seminal fluid and amniotic fluid. Pepsinogen concentration in blood or urine is changed when gastrointestinal or renal diseases occur. So pepsinogen concentration in blood and urine can be used as an index of many gastrointestinal diseases and renal diseases. In this investigation, we analyse pepsinogen I concentration in blood and urine in six gastrointestinal diseases. The results are as follows. 1) The pepsinogen I concentration in blood is lowest in chronic atrophic gastritis(36.8 ng/dl) and high in gastric ulcer(131. 3 ng/dl) and duodenal ulcer(118. 7 ng/dl), (p<0.01, p<0.05). 2) The pepsinogen I Concentration in urine is lowest in Chronic atrophic gastritis(236ng/dl) and highest in duodenal ulcer(913.3 ng/dl), (p<0. 01). 3) The pepsinogen I concentration in blood and urine can be used as a diagnostic index of peptic ulcer diseases, chronic atrophic gastritis and recurrence of peptic ulcer after operation.

Recently, there has been a rapid increase in the agricultural use of pesticides throughout the world. In Korea, the amount of pesticide consumption has increased more than 15 times during last 14 years(1965-1979) and this, consequently has become a serious health hazard to the farmers. The author interviewed with 403 farmers who had sprayed (once at least or more) the organophosporus pesticides during the summer(May thru' September) of 1981 and investigated, with a predesigned questionnaire from, the rate and clinical manifestation of poisoning, a safety or preventive measures carried out and the type of treatment given. The result was as follows. 1. Among 403 tarmers interviewed, 79 experienced one or more of the symptoms of poisoning. Applying this rats to entire farming population(5,765) of the village, the estimated number of poisoning this summer was about 400(6.9%, age adjusted), Of these, 60.8% was classified as mild in severity, 26.6% moderate and 12.7% severe. 2. Symptoms and signs experienced after the spray; the order of frequency was the same as that of other investigators, while the rate of appearance of each symptom was generally lower. 3. Use of protective devices; 163 cases wore mask alone (made of gauze), 88 cases mask and gloves and another 88 cases used no protective device at all. The highest rate of protection was observed in those worn both mask and gloves. 4. No safety education has been given to any one of the farmers investigated. Most(90.6%) of the respondents obtained the information about the pesticide by reading the direction attached to the package, from colleagues or someone in the agricultural advisory office of the area. After the spray, 84.9% of the respondent took bath and 93.5% took direction of wind into consideration during work. 5. In spite of their deep concern with the prevention of poisoning as shown above, their attitude toward the medical care of the poisoned was quite dissatisfactory. Only a quarter of the poisoned visited a clinic and one third of severe cases (with disturbance of consciousness) did not receive treatment by the physician. Even those visited a clinic missed the chance of early treatment simply by waiting and seeing at home.

In a study of 460 cases of upper gastrointestinal bleeding admitted in Han Yang Univeraitp IIoaptal during the 6 pear period 1978-1983 inclusive, the following results were obtained: 1) The male-female ratio was 5:1 and peak ineidnce was in the 5th-6th decade. 2) The causes of bleeding were; esophageal varicea in 26.1, duodenal ulcer in 23.0, gastric ulcer in 20.7io, erosive gastritis in 10.2%, stomach cancer in 3.'/, Mallory Weiss syndrome in 1. 3%, marginal ulcer in 0. , and gasfiric polyp in 0. 2. The incidence of no positive diagnosis was 14.1%. 3) The frequencies of previous blaeding were; no previous bleeding history in 16.1, and two and mare previous bleeding histories in 6.5%. 4) 13. 0 of the patients had possible precipitating 'Factors of bleeding. Alcohol waa the moat commian precipitating factor with its incidence of 5.4. 5) Three main types of bleeding on admission were; hematemesis in 36. 7, melena in 34. B%, and the two combined in 28. 5 , 6) The patients given a transfusion were 78.9. The patients receiving more than 10 pinto of blood were i4.6. 7) The ABO blood groups were; group 0 in 35.6, group A in 29.6, group B in 20.9, and group AB in 9.5. 8) 90.8% of the patients were treated medically and 9. 2 o of the patients received operations. The treatments on the rupturod oesophageal varices were; medical treatments in 16.1 %, endoacopic injection aclerotherapy in 8.5, and olrerations in 1.5%. 9) Among 460 cases, 76. 5 of the patients improvesi, 14, 3'/0 of the patients discharged under the poor condition, and 9.1 of the patients expired during the hospitalisation. Important factors; affecting the prognosis were the caqaes of bleeding, the types of bleeding on admission, the systolic blood pressure on admisaron, the BUN level on admission, and the amounts of blood transfused.
