Nine cases of human infection with Strongyloines stercornlis are reported among patients admitted to the Seoul Paik and Sang-Kye Paik Hospitals, Inje University, from April 1990 to Junuary 1992. The Patients, 7 males and 2 females acted between 50 and 70, either had the history of long term use of steroids for management of arthritis, or were complicated with other chronic diseases such as hypertension, liver diseases, psychotic disorders, and gastrointestinal problems. All of the nine patients revealed rhabditoid larvae of S. stercorolis in fecal examination. A 57-year-old woman who complained of arthritis and abdominal discomfort, was treated with albendazole and mebendazole, and on the 4th and 5th treatment day 220 parasitic adult females were collected from the diarrheal stool. The patient had a long history of administration of steroids for treatment of arthritis, and seems to have suffered from hyperinfection syndrome due to autoinfection with S. stercordis. This is the 3rd report on the recovery of parasitic adult females of S. stercoraLis in Korea.

Entomopathogenic nematodes were isolated through the investigation of soil samples from various biotopes in south Korea, the efficiency of isolation for highly pathogenic nematodes to silkworms (Bombyx mori) was as high as 28 %. Twenty-eight strains of nematodes, selected among 100 samples by silkworms were confirmed the pathogenicity, multiplicity, and tolerance against various condition of preservation. Pathogenicity of the nematode isolates to agricultural and environmental pests such as Calliphora vomitoria, Pseufaletia separata, Palomena angulosa, and Melolontha incana were high. Mortality was varied from 20 to 100% by the pest insects and nematode strains. The high detectablity of entomopathogenic nematodes resulted from the methods of collection for soil samples within 10 cm depth after eliminating dried soil surface and the use of silkworm trap. High population of entomopathogenic nematodes represented the strong activity and broad action radius in the environment. Most of the nematode isolates were successfully cultured on the silkworm host as well as on artificial media, and proved their potential for the use of biological control agent.

This 54-year-old Korean coal miner soBered from continuous watery diarrhea and weight loss after corticosteroid treatment(${\beta}-methasone$, 4 mg daily for 1 week) due to hip-bone fracture in January 1991. Except for the short therapy f steroid, no other histories were contributory. The malabsorption syndrome was aggravated while the case was treated under the impression of amebiasis or intestinal tuberculosis. AIDS antibody test by EIA was negative and quantitative analysis of serum immunoglobulins was in normal ranges. Nine months after the onset of symptoms, the case was diagnosed as malabsorption syndrome caused by complected and aggravated infection by Strengyleides stercoralis, Isospora and cytomegalovirus in the small intestine, which were proved by stool examination and duodenal biopsy. His clinical course became worse even after high-dosaged and prolonged albendazole treatment for strongyloidiasis with supportive quid therapy. The patient was discharged in hopeless status in November, 1991 and died after one week at home.

Strongylodiasis is universal in distribution but is most abundant in countries with a tropical climate. Although infestation by Strongyloides stercoralis is usually limited to the intestines, dessemination of this helminth in debilitated host can be lead to death with various clinical disorders, characterized by profound malabsorption, diarrhea, electrolyte imbalance, gram negative or opportunistic fungal sepsis, coma and death. Cell-mediated immunity contributing significantly to the control of helminthic infections, may be suppressed by carcinoma, immunosuppressive chemotherapy and use of corticosteroids. Diagnosis of Strongyloidiasis is achieved by an examination of samples of feces, duodenal aspirates and sputum of patients for Strongyloides stercoralis. Treatment of strongyloidiasis is twofold: correction of the immunosuppressive state by withdrawal of immunosuppressive drug, if possible, and vigorous treatment with thiabendazole. Testing for strongyloidiasis is especially recommanded before treating a patients should be monitored for infection by Strongyloides stercoralis and other opportunistic infection. We are reporting a case patient with Strongyloides stercoralis hyperinfection and pulmonary tuberculosis who had been used corticosteroid for persisting polyarthritis.

참외의 시설재배면적이 증가함에 따라 재배기술과 소득은 향상되었으나 동일한 시설 내에서 같은 작물을 연작하고, 연중재배하므로써 연작장해가 많이 발생하고 있다(박 등, 1988). 연작장해의 주요 요인으로는 토양양분의 소모, 토양양분의 질적 악화, 토양반응 및 토양물리성의 악화, 독소의 집적, 토양병해충을 비롯한 유해 토양미생물의 증가 등을 들 수 있다(이, 1996). 특히 우리나라 시설재배지에서는 무기양분이 노지처럼 유실되지 않고 토양에 잔존해 있기 때문에 염류의 집적이 노지보다 많은데도 불구하고 다량의 가축분이나 무기양분을 과다시비하므로써 염류집적이 가중되고 있다.

A case of Strongyloides stercoralis infection was experienced in a 73-year old Korean female patient, was hospitalized with relapse of cholecystitis. The patient developed cough and dyspnea 17 days after the admission. On the 27th hospitalized day, diarrhoea, nausea, vomiting and abdominal pain started. A number of parasitic larvae were incubated at $25^{\circ}C$ for 2 days. Typical fork tailed filariform larvae of S. stercoralis (Bavay, 1876) Stiles and Hassall, 1902, were identified after cultivation. There was no improvement of diarrhoea after the medication with mebendasole. After the administration of thiabendazole, however, diarrhoea was stopped. On the 6th day of medication, S. stercoralis larvae was no more detected, and thereafter no larva was observed by repeated stool examinations upto 2 months after chemotherapy. The patient had the history of administration of steroid for articular rheumatism. Therfore this ,case seems to be a hyperinfection of S. stercoralis due to an autoinfection and to be the first report on the hyperinfected strongyloidiasis in Korea. Related literature was briefly reviewed.

Strongyloides stercoralis is an intestinal nematode that is a parasite to humans. The infecting filariform larvae of S. stercoralis enters the host body via the bloodstream, passes through the lungs, penetrates the alveoli, and then ascends the airway to transit down the esophagus into the small bowel. The infection can persist for decades without causing major symptoms and can elicit eosinophilia of varying magnitudes. Of note, this infection can also develop into a disseminated, often fatal, disease (hyperinfection) in patients receiving immunosuppressive corticosteroids. A 65-year-old man who was receiving corticosteroid therapy for the treatment of spinal stenosis was admitted to the emergency room with complaints of abdominal pain and severe dyspnea. We detected many S. stercoralis larvae in the sputum and in the bronchoalveolar-lavage sample collected by bronchoscopy. Here, we report a fatal case of strongyloidiasis with acute respiratory failure and intestinal perforation. In addition, we provide a brief review of the relevant medical literature.

The required energy for the heat treatment of pine log was evaluated in this study. A proper heat treatment of pine log infected by pinewood nematode (Bursaphelenchus xylophilus) can prevent spreading of the infection by pinewood nematode and make the infected pinewood valuable again. The FAO (Food and Agriculture Organization of the United Nations) heat treatment standard for various types of infected wood for which a heat treatment of the core part of the wood is necessary is 30 minutes at $56^{\circ}C$, taking into account the international standards for phytosanitary measures (ISPM No. 15). In this study, the energy consumption during the heat treatment was separated into two kinds of energy, initial energy for heating kiln drier and to reach set point temperature and relative humidity and the required energy supplementing heat loss. The initial required energy per unit time is greater than that during the treatment. The energy consumption per unit time varied little during the heat treatment. As a result, the set point relative humidity with set dry bulb temperature and density of wood dependent on moisture content are very important factors to change energy consumption in the experiment. The heat treatment at higher temperature and higher humidity levels requires more energy consumption but less treatment time. It is expected that a more effective energy program could be planed for the heat treatment of pine log through this study.
