In Korea where night soil used as fertilizer for crops and vegetables they may be contaminated simultaneously with infective stage of ascaris, hookworm and other helminthes. In this circumstance, the ascaris eggs and hookworm larvae may adhere to certain kinds of leafy vegetables(Chyu, 1957) and may remain viable even after pickling in brine or in other substances (Han and Ko, 1952; Soh, 1960). It has been shown that Heliogen(Thitasut, 1961) will kill the parasite eggs and larvae, and Sodium nitrite (Kozai, 1960; Kim and Soh 1964) and Thiabendazole (Kutsmi, 1964 and 1965; Kim et al., 1966) also had ovicidal action. The present study has been planned to study the ovicidal and larvicidal actions of several chemicals in Korean pickle juice(Kimchi) and the results are summarized as follows: Heliogen solution(iodine 100 ppm) did not destroy the ascaris and hookworm eggs within 30 minutes at the temperature of 15-30 C, but the hookworm larvae were killed within 3 minutes under the same conditions. Sodium nitrite which was added to pickle juice at the rate of 0.1 percent destroyed more than 90 percent of ascaris fresh eggs within 10 days and the embryonated eggs were destroyed within 2 days. Hookworm eggs were destroyed within 3 days and larvae were killed within 7 hours. Thiabendazole which was added to pickle juice at the rate of 0.1-0.025 percent inhibited the infectivity of ascaris embryonated eggs within 24 hours and hookworm eggs were destroyed in the same concentrations of the reagent. Hydrogen ion concentration of pickle juice which was mixed with Sodium nitrite (0.1 percent) was not changed for 10 days. 1.5 mg of Sodium nitrite or Thiabendazole produced no toxicity in kidney and intestine of mice but slight pathological changes in the liver of the same animal.

A 63 year-old man was admatted to our hospital because of dulI epigastralgia. Upper G-I series reveaied the generalized thickened, tortuous mucosal folds in the stomach and duodenal bulb, Two ovold large pits on the antrum were observed endoscopically, Tha relevant literatures on the subject were reviewed.

We report a case of myiasis on the left submandibular area after radiation therapy for squamous cell carcinoma. A 77-year-old man visited our hospital, 7 weeks after complicating a course of radiation therapy, had a 7cm diameter necrotic ulcer on the left submandible. The margin of the lesion were undermined by numerous interlinking passages containing 20 maggots. The maggots were removed by simple extraction and were identified as Calliphoridae Lucilia. The probable origin of the myiasis in this case was attributed to poor environmental condition and general weakness of the patient. Oppotunistic cutaneous myiasis can be prevented by protecting open wounds from flies, wound should not be left without a covering capable of excluding flies, especially in the summer month.

PURPOSE: To evaluate the efficacy of arthroscopic microfracture in patients with focal full-thickness cartilage defects in the osteoarthritic knee. MATERIALS AND METHODS: Seventy-six patients were enrolled in this study. They were divided into group I (n=38) who underwent microfracture plus meniscectomy and group II (n=38) who underwent only meniscectomy. Clinical and radiological evaluations were performed. RESULTS: At the time of the three-year follow-up, a total of five failures (6.6%) were reported: four patients in group I and one in group II. The two groups showed no significant difference in the Lysholm score, the Tegner activity score and the visual analog pain scale score at three years after surgery. However, at the time of the three-month follow-up, group II showed significantly more improvement in the Tegner activity and the visual analog pain score compared with group I. CONCLUSIONS: In the osteoarthritic knee, additional microfracture did not confer any additional benefit to meniscectomy.

In this report, we describe the findings of diffusion MR imaging and proton MR spectroscopy in two infants with acute necrotizing encephalopathy in which there was characteristic symmetrical involvement of the thalami. Diffusion MR images of the lesions showed that the observed apparent diffusion coefficient (ADC) decrease was more prominent in the first patient, who had more severe brain damage and a poorer clinical outcome, than in the second. Proton MR spectroscopy detected an increase in the glutamate/glutamine complex and mobile lipids in the first case but only a small increase of lactate in the second. Diffusion MR imaging and proton MR spectroscopy may provide useful information not only for diagnosis but also for estimating the severity and clinical outcome of acute necrotizing encephalopathy.

The very rare D--/D-- phenotype lacks C, c, E, e antigens with strong expression of the D antigen. A 31-year-old woman delivered her second baby, 3.6 kg girl at 38+4 weeks' gestation through repeat-Cesarean section. Her parents were not consanguineous. She had one artificial abortion, one Cesarean section with red blood cell transfusion and two spontaneous abortions. Her red cells were typed as O, D+C-c-E-e- and did not react with anti-Hr(o) (Rh 17). Her serum reacted with all of the screening cells and identification panel cells with strength of (++)~(+++). The baby was mildly jaundiced 12 hours after delivery. At 1 day after delivery, total bilirubin was 17.7 mg/dL, and direct and indirect antiglobulin tests were both positive. Phototherapy was immediately given for the baby but jaundice and anemia were worsened. Twenty six milliliter of the mother's whole blood was given twice to the baby after plasma depletion and leukocyte reduction. The baby showed improvement of jaundice and anemia, and discharged at hospital day 14. As far as we know, this is the third reported case of hemolytic disease of the newborn occurred in the D--/D-- mother with anti-Hr(o) in Korea, and the first case that was neither fatal nor treated with intensive medical care.

Anti-thrombin III deficiency is known as a disease of autosomal dominant trait and relatively common, but in Korea, exact incidence and mortality is not known, In general, Anti-thrombin III deficiency is expressed to venous thromboembolism like deep vein thrombosis or pulmonary embolism. But, arterial embolism is very rare. We experienced a case of Antithrombin III deficiency expressed as myocardial infarction of inferior wall by huge thrombosis in the mid and distal right coronary artery.

The diagnosis of acute inflammation of the placenta, represented as acute chorioamnionitis, is important in that it is associated with a poor clinical outcome for both the mother and the fetus, including major perinatal morbidities such as sepsis, respiratory distress syndrome, and CNS damage. However, current medical trends in Korea seem to overlook the significance of a histopathological diagnosis of acute placental inflammation, mainly due to the indifferences of clinicians and pathologists. Since late 1993, histopathological examinations have been performed on preterm placentas at Seoul National University. These examinations have demonstrated acute placental inflammation in a significant number of cases. In the present study the incidence of acute placental inflammation was analyzed in 521 placentas which were submitted for pathological examinations in 1995. Examinations were performed to provide basic information on the incidence and profile of acute placental inflammation in this hospital and, thereby, to emphasize the significance of histopathological examinations of the placenta in the routine surgical pathology service. Among the 521 placentas, acute inflammation was found in 194 cases (37.2%). In preterm placentas acute inflammation was found in 39.6% of the cases (67/169), while 36.1% (127/352) of term placentas showed acute inflammation. Taking the delivery mode into account, 26.3% (49/186) of the placentas delivered by cesarean section showed acute inflammation, while 43.3% (145/335) of the transvaginally delivered placentas showed inflammation. The present analysis demonstrates the existence of acute inflammation in a significant proportion of placentas with different clinical settings. The importance of a histopathological examination in routine hospital practice should be emphasized.
