A 36-year old Korean woman consulted a clinic for a regular gynecological examination, and a mass was noticed in her pelvis. She was referred to the Asan Medical Center, Seoul where transvaginal ultrasonography confirmed a pelvic mass exceeding 10 cm in diameter. She received total abdominal hysterectomy and bilateral salpingoophorectomy, and a borderline serous neoplasm with micropapillary features involving the left ovary and right ovarian serosa was histopathologically confirmed. In addition, a section of a nematode with numerous eggs was found in the parenchyma of the left ovary. The worm had degenerated but the eggs were well-preserved and were identified as those of Enterobius vermicularis. She is an incidentally recognized case of ovarian enterobiasis.

The authors reported a case of ectopic paragonimiasis in a 40 year old Korean housewife who came to the hospital because of abdominal mass and pain. She was proved to have multiple parasitic granulomas involving lung, uterus, uterine tube and subcutaneous tissue. The ovary was also the site of parasitism. The past history revealed an episode of ingestion of fresh water crabs soaked in soybean sauce which were obtained in a market of Seoul City 2 years prior to the present illness. The patient was treated for tuberculosis for a year without confirmation of etiologic agent. After surgical removal of all abdominal and most of pelvic granulomas, the patient was treated with praziquantel 25 mg/kg t.i.d. for 3 days, and was judged to be cured after 4 months.

A Study on glutamic pyruvic and oxaloacetic transaminase of different organs(e.g intestine, seminal vesicle, reticular tissue, uterus, ovary, testes) in Ascaris lumbricoides suis have been investigated. The activity of transaminase were determined on the whole homogenates and subcellular fractions separated by differential centrifugation. The activity of glutamic pyruvic and oxaloacetic were assayed by colorimetric method of Reitman-Frankel. The results were obtained as follows: About ninty percent of the glutamic pyruvic and oxaloacetic transaminase in different organs was found to be localized in the supernatant fraction with the separation of differential centrifugation. And it was found that ten percent of glutamic pyruvic and oxaloacetic transaminase exists in the mitochondrial fraction. The specific activity of glutamic oxaloacetic transnaminase in different organs was relatively higher than the glutamic pyruvic transaminase activity.

The developmental features, growth and organogenesis of Macroorchis spinulosus were observed in albino rats. Globular and thick walled metacercariae, possessed a stylet, Y-shaped excretory bladder and extracecal testes. In albino rats, M. spinulosus showed habitat shifting. The majority of M. spinulosus reside in the jejunum for the first four days post infection (p.i.) and migrate to the duodenum at the later stage of infection. M. spinulosus grew rapidly during the first four days and reached full maturity at 14 days p.i. and later reduced in size. The ovary was separated from the genital primodium at one day p.i. The seminal vesicle appeared on the third day and divided into two sacs on the fourth day p.i. and intrauterine eggs and sperm mass were produced on the fourth day. Organogenesis and enlargement of reproductive organs governed the growth of M. spinulosus. The similarity of related species of the genus Macroorchis to M. spinulosus was discussed in consideration to developmental features.
