The present study was undertaken to observe the quality and quantity of lipid constituents by the developing Ascaris suum eggs. The collected eggs from the uterus of A. suum were classified into 3 groups, i.e., single cell stage, morula stage and embryonated eggs, and were subjected to analyse their lipid fractions. To obtain the morula stage eggs, 10 to 11 incubation days at 30 degree C were needed and for the embryonated eggs, 30 to 31 days were lasted. At the time of experiment, their indices of development by Hoffman were 285(morula stage) and 42 (embryonated stage) respectively. Lipid extraction was done by the methods of Folch et a1. (1957) and Kenny (1952), and then the extracted lipid fractions from the above 3 groups of eggs were separated by thin layer chromatography. Those fractions were also subjected to perform the quantitative analyses of fatty acids, glycerides, cholesterol and phospholipids. The results obtained were summarized as follows. Total amount of fatty acid was decreased from 12.9 mg per gram of eggs (single cell stage) to 6.6 mg/gm (embryonated eggs), whereas the proportion of free fatty acid to total fatty acid was constantly increased from 77.5 percent to 89.4 percent during the period of egg development. Total amount of glycerides was also increased from 33.0 mg/gm of single cell stage to 55.9 mg/gm of the embryonated eggs. The most abundant glyceride among 3 glycerides discovered from A. suum eggs was triglyceride, and the least was monoglyceride. The amount of free cholesterol was much larger than that of ester form in general, and it reached maximum in the eggs of morula stage (4.6 mg/gm). The increase of total cholesterol was monitored during the development of A. suum eggs from 3.3 mg/gm to 5.4 mg/gm. The following 8 phospholipids were detected in the embryonated eggs, i.e., lysophosphatidyl choline, phosphatidyl inositol, sphingomyelin, phosphatidyl choline, phosphatidyl glycerol, phosphatidyl serine, phosphatidyl ethanolamine and unknown phospholipid. But in the single cell stage eggs, 4 kinds out of the above 8 phopholipids were not observed, and in the morula stage eggs, 2 kinds were absent among the 8 phospholipids.

A perplexing developmental error is 46,XX congenital absence of vagina ( Mayer-Rokitan-sky-Kster-Hauser syndrome, Mullerian dysgenesis, vaginal aplasia ). The Mayer-Rokitansky-Kster-Hauser syndrome refers to the climical entity consisting of primary amenorrhea associated with congenital absence of the vagina, 46,XX karyototype, a rudimentary uterus or complete absense, normal overian function and normal ovulation, normal female breast development, body proprotion and body hair, frequent association of renal, skeletal and other cpngenital anomalies. This syndrome results from agenesis of both Mllerian ducts or from a failure of the Mllerian ducts to estavlish a proper communication with that part of the vagina from the urogenital sinus. A case of mayer-Rokitansky-Kster-Hauser syndrom was reviewed briefly.

This study was carried out in order to find out the valuable measure to kill the parasite eggs in night soil. The fresh eggs of Ascaris put into human stool were irradiated with Cobalt 60 of 200,000 to 1,000,000 rad and cultured in test tubes at 25-30 C, washing with 2 percent formalin solution every 24 hours. The continuous development of those eggs were observed under microscope and the proprotions of developed eggs were compared with those of control groups. The major result can be summarized as follows: In general, The eggs in stool developed poorly than the eggs in saline. If the eggs were irradiated with the larger dose of Cobalt 60, the proportion of developed eggs were reduced subsequently. The eggs irradiated with the dose of 1,000,000 rad in saline developed in the proportion of 15.5 percent, whereas irradiated with 200,000 rad 94 percent developed in 4 weeks. The 44.5 percent of eggs in stool irradiated with 200,000 rad developed after 4 weeks, 30.5 percent with 300,000 rad, 25 percent with 500,000 rad and 3.5 percent with 1,000,000 rad respectively. The effective minimum dose of Cobalt 60 irradiation to kill the Ascaris eggs in stool was estimated 1,000,000 rad. Further examination will be required to observe the infectivity of irradiated Ascaris eggs to animals and to evaluate the effect from the standpoint of sanitary engineerings.

A recent study showed that comparative sequence analysis of rpoB DNAs could reveal natural relationships in genus Mycobacterium [J Clin Microbiol. 37 (6). 1999]. rpoB DNAs showed interspecies variation and intraspecies conservation, Based on these data, we developed polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) protocols which enable species differentiation in genus Mycabacterium. When this assay was applied to 24 clinical isolates identified as M. avium complex (MAC) by biochemical test, these were successfully differentiated into M. avium and M. intracellulare. These results were concordant with those obtained by 16s rDNA analysis. It is the first report that PCR-SSCP analysis of rpoB DNA could be used for species differentiation of MAC strains.

Hantavirus pulmonary syndrome(HPS) is a systemic disease that is caused by a newly discorved and characterized virus of the Hantavirus genus, which is most frequently referred to as the sin nombre virus. The clinical syndrome resembles other hantavirus syndromes worldwide, except that it is characterized by a brief prodromal illness followed by rapidly progressive, noncardiogenic edema, and that it is more deadly than any previously recognized hantavirus infection. The clinical manifestations of HPS are characterized by four clinical phases prodrome, pulmonary edema and shock, diuresis, and convalescence. Mortality is greatest in the first 24 hours of the pulmonary edema and shock phase of the illness. These phases are strikingly similar to the clinical phases of Hemorrhagic fever with renal syndrome(HFRS) induced by Hantaan virus, except that HPS has not been associated with renal failure and Disseminated intravascular coagulation(DIC). We here report a case of hantavirus pulmonary syndrome developed in a 58 year-old man. He had a flu-like illness followed by the rapid onset of respiratory failure due to noncardiogenic pulmonary edema. HPS was diagnosed by clinical manifestations, identification of high titer antibody to Hantaan virus antigen and histologic finding of transbronchial lung biopsy (TBLB) specimen. The patient was treated with mechanical ventilation and initial corticosteroid pulse therapy resulting in successful outcome.

Botryomycosis is a rare, chronic and suppurative di- sease that is often mistaken clinically and histologically for a fungal infection, because the histologic feature shows a cluster of bacteria found within an eosinophilic matrix or capsule, giving the appearance of granules mimicking the sulfur granules of actinomycosis. Staphy- lococcus aureus is the most common organism cultured from lesions of botryomycosis, but other bacteria have also been isolated and implicated, including Psudomonas aeruginosa, E. coli, Proteus spp., Bacillus spp.. In some case, multiple pathogenic bacteria were found on cul ture. This disease has two patterns of organ involve ment. The more common type is cutaneous type, which involves the skin, subcutaneous soft tissue, muscle and bone. The other is visceral type which involves the lungs, liver, tongue, orbit, bowel, brain, kidney or pros tate. We report a case of brain and pulmonary botry omycosis in a 60 year-old man, who have early lung cancer. Botryomycosis was diagnosed by brain mass removal, PCNA and bronchoscopy, and lung cancer was detected incidentally by bronchoscope. The patient was treated with the Penicillin G after operation of brain mass, and right pneumonectomy was done.

Conventional tests for the identification of mycobacteria may frequently result in erroneous identification and underestimate the diversity within the genus Mycobacterium. However, this problem can be overcome by molecular approach like as 16S rRNA gene (rDNA) or RNA polymerase gene (rpoB) sequence analysis. In this study, a molecular approach analyzing partial sequence of 16S rDNA and rpoB gene was applied to mycobacteria other than M tuberculosis (MOTT) isolates that had not been definitely identified by conventional physical and biochemical tests. Among the eighteen isolates included in this study, twelve isolates could be identified to the species level and six were identified to the complex level. Compared with the results by 16S rDNA analysis, the rpoB analysis could di6erentiate some of the strains into the subspecies level.
