Most instances of choriocarcinoma of the ovary are gestational in origin. In contrast, nongestational choriocarcinoma of the ovary is an exceedingly rare primary germ cell neoplasm that has worse prognosis than gestational neoplasm. We report a case of pure nongestational choriocarcinoma of the ovary in view of the rarity of its kind. The patient was a 35-year-old Korean unmarried woman who had suffered from vaginal bleeding and feeling of abdominal inflation for two months. The X-ray studies and CT scanning revealed a child head sized cystic mass on the right pelvic cavity and multiple nodular densities in both lung fields and the liver. The mass in pelvic cavity was excised and histologically confirmed to be a nongestational pure choriocarcinoma, arising from the right side ovary.

OBJECTIVE: The objective of this study were to clarify the significance of PCNA and DNA ploidy as a possible parameter of the prognosis in squamous cell carcinoma of the uterine cervix. STUDY DESIGN: Women with the diagnosis of cervical cancer operated between January 1987, and July 1991, composed the study group(n=35) in this case-control group. Among these 35 patients.In theese patients we chose the patients with complete follow up treatment. Also we employed 7 control paraffin-embedded cervical specimens without any specific pathologic lesions for the comparison. Immunohistochemical staining to identify PCNA was applied to case of paraffin section and PCNA indices was obtained. DNA analysis was done by using flow cytometry and S-phase fraction and DNA ploidy were obtained. RESULT: The results were summarized as follows. 1. S-phase fraction were 20+/-7% in cervical cancer and 16+/-11% in control group. There were no statistical difference. Aneuploid ratio were 26%(9/35) in cervical cancer and 0%(0/7) in control group. There were statistical difference. PCNA indices were 45+/-6% in cervical cancer and 5+/-4% in control group. There were statistical difference. 2. There were no statistical difference in PCNA indices between large cell keratinizing type, and large cell nonkratinizing type of cervical cancer. 3. According to lymph node metastasis, there were no statistical difference in PCNA indices between positive group and negative group.4. According with various pathologic parameters, recurrence rate was hihger in cases of parametrial involvement. 5. The correlation of coefficient was 0.747 between PCNA indices and S-phasd fraction that is a significant relationship.6. According to recurrence, there were no statistical difference in S-phase fraction, aneuploidy and PCNA indices between group of recurrence and no recurrence.7. There were no statistical difference between <20% group nad>20%, group of S-phase, aneuploid and <60%, group and >60%, group of PCNA index in view of recurrence rate. conclusion: That is a significant relationship between S-phase fraction and PCNA indices, But, there are no statictical significance of PCNA indices, DNA ploid and a prognostic factor. So, that is a limitation in PCNA index DNA ploid when it was used as as prognostic parameter of nterine cervical cancer.

Control of tuberculosis is threatened by widesread emergence of drug resistant Mycobacterium tuberculosis. Rifampin is a key component among therapeutic regimens for the tuberculosis; therefore patients in whom resistance to this drug develop have a poor outlook, particularly if rifampin resistance is associated with resistance to other tuberculosis drugs. The purpose of this study was to detect the mutation in rpoB gene of rifampin resistant M. tuberculosis in Korea and to evaluate the usefulness of the method in clinical aspects. A sample of 80 M. tuberculosis was studied, and it included 40 rifampin resistance isolates and 40 rifampin sensitive isolates by conventional methods. The detection method involved the amplification by polymerase chain reaction (PCR) of the Rif' region and the identification of mutations by single-strand DNA conformation polymorphism analysis (SSCP) of the amplification products (157 bp). Mutation were identified in 39 of 40 rifampin resistant isolates, and in 1 of 40 rifampin sensitive isolates.

Control of tuberculosis is threatened by widespread emergence of drug resistance in Mycobacterium tuberculosis. Understanding the molecular basis of resistance might lead to development of novel rapid methods for diagnosing drug resistance. Rifampin is a key component among therapeutic regimens for the tuberculosis; therefore, patients who have drug resistance do not convalesce satisfactorily. The molecular mechanism of resistance to rifampin in M. tuberulosis has been elucidated. Substitutions of a limited number of highly conserved amino acids encoded by the rpoB gene are responsible for the ""single-step"" high-level resistance of M. tuberculosis to rifampin. Currently, two genotype-based protocols allow drug test from minimally grown cultured materials: (i)mutation identification by direct sequencing of PCR-amplified material. and (ii)mutation screening by PCR-SSCP. The purpose of this study is to evaluate the usefulness of the both methods. A sample of 75 isolates of M. tuberculosis was studied, and it inculded 36 rifampin-resistant strains and 39 rifampin-sensitive strains by conventional methods. Mutaions were identified in 36 rifampin-resistant isolates but in none of 39 sensitive isolates. All mutations were clustered within a region of 23 amino acids. Both methods allow detection of rifampin resistance in 2 to 3 days and will thus help in the early management of infection by M. tuberculosis.

Multicystic ovary was first described by Silver in 1958 as a rare case feature of acquired primary hypothyroidism. In 1980, Lindsay reported four girls with hypothyroidism associated with multicystic ovary diagnosed by pelvic ultrasonography. The mechanism of ovarian cyst formation and pseudoprecocious puberty in severe hypothyroidism in childhood are unknown. Increased ovarian sensitivity to GnRH and increased TSH level which acts on FSH receptor is one of the mechanism explained. We report a case of a girl with primary hypothyroidism presented with pseudoprecocious puberty and giant follicular ovarian cyst with torsion.

A case of Tuberous Sclerosis, 4 year-old-Korean boy was observed. He had some symptoms about Tuberous Sclerosis which were abenoma sebaceum, seizure, shagreen patch and hypopigmented macule. Diagnosis was confirmed by facial skin biopsy and adenoma sebaceum was noticed.
