Growth under conditions of iron-restriction and the production of siderophore was examined in Vibrio mimicus ATCC 33653. This strain grew and multiplied in the presence of the high-affinity iron chelators ethylenediamine-di (o-hydroxyphenylacetic acid). Chrorne azurol S (CAS) agar and solution were used to detect the production of siderophore under these condition. Siderophore could be detected in the iron-rcstricted culture supernatants. The siderophore was extracted from iron-restricted culture supernatants by phenol-chloroform-ether method and purified by Dowex ion-exchange and Sephadex G-25 gel filtracton chromatography. The purified siderophore was confirmed by paper chromatography and HPLC. The Purified siderophore enhanced the growth of V. mimicus when the bacterium was grown in iron limited medium. Injection of both the siderohore and the bacteria to mice resulted in more rapid death than that of the only bacteria. However, the siderophore did not show lethality to mice and any toxicity to cell line like HeLa and U937.

Pulmonary endometriosis is a rare disease which is characterized by hemoptysis during menstruation (catamenial hemoptysis). We report a case of pulmonary endometriosis in a 33-year-old housewife. She has had regular menses with moderate flow and minimal dysmenorrhea. She had undergone curettage in May 1995 for artificial abortion. In July 1995, she experienced the first episode of hemoptysis. A chest CT scan revealed a 2.0 1.0 cm sized ill-defined soft tissue density in the periphery of anterior segment of the left upper lobe with a surrounding irregular ground-glass opacity. A left upper lobectomy was done under the diagnosis of pulmonary endometriosis. Cut section of the resected lung showed a round red-brownish solid lesion, measuring 2.0x1.0cm in cross. Microscopically a focus of the endometrial tissue, which was composed of endometrial glands and stroma, was found in the lung parenchyme and many hemosiderin laden macrophages were seen in the surrounding alveoli. The postoperative course was favorable with no further episodes of hemoptysis.

Two hundred sixty six children were retrospectively surveyed from first to fifth grade to find out the status of obesity during four years. The obesity index was gained by height and weight data from student's health file and the data about eating behaviors and weight control behaviors, etc. were collected by questionnaires. Children assigned to one of the following groups : underweight, normal, overweight and obese. The results were as follows ; 1. Obese children were 18.6%(n=27) of boys and 10.8%(n=13) of girls at fifth grade. 2. Twenty eight children among forty obese children at fifth grade were also overweight or obese at first grade, and the other twelve was normal. 3. Breakfast skipping rate was significantly high among underweight and obese group of boys(p<0.01).The most children(8736%) had prejudice for special foods. 4. The rate of agreement between obesity index and self recognition of body image was 60.7% in boys and 63.6% in girls. 5. Forty two point five percent of children have ever tried weight control as exercise(35.7%), reducing sugars and snacks(27%), feasting(23.8S%), avoiding fatty foods(12.7%), taking diet food or drug(0.8%). In conclusion, the prevalence of children obesity is gradually increasing and children tried weight control without right guidances. In order to prevent progress into adulthood obesity, nutrition education should be followed with school foodservice including the right perception for obesity, proper weight control and eating behavior modification.
