3.Tissue-specific Expression of DNA Repair Gene, N-Methylpurine-DNA Glycosylase (MPG) in Balb/c Mice without External Damage.
Journal of Genetic Medicine 1998;2(1):31-34
The N-methylpurine-DNA glycosylase (MPG), a ubiquitous DNA repair enzyme, removes N-methylpurine and other damaged purines induced in DNA. Tissue-specific mRNA levels of the N-methylpurine-DNA glycosylase (MPG) were investigated in Balb/c mice of four different growing stages; newborn, 1, 4 and 8-weeks postpartum. MPG expressions in the newborn and the 8-week-old mice were the highest in thymus and testis, respectively. The tested tissues of the newborn mice had consistently higher MPG mRNA level than 8-week-old adults except in testis and thymus. The MPG mRNA level in testis was the lowest in the newborn mice, but it attained the highest in the 8-week-old mice. The levels of MPG mRNA among the different tissues in the newborn and the 8-week-old mice were more than 9.0 and 19.0-fold respectively. These results suggest that the of MPG expression was dependent on the growing stage and had tissue-specificity.

OBJECTIVE: To report the pregnancy which was made by in vitro fertilization using recombinant follicle stimulating hormone and gonadotropin releasing hormone antagonist. MATERIAL AND METHOD: Case report. RESULTS: Six oocytes were retrieved and all were fertilized by intracytoplasmic sperm injection. Six embryos were transferred and the pregnancy was confirmed. CONCLUSION: It is envisaged that the availability of recombinant gonadotropins and gonadotropin releasing hormone antagonists will ultimately lead to shorter, cheaper and safer treatments, using reduced dosages.

PURPOSE: This study was conducted to analyze industrial workers' stresses from physical symptoms, PWI, JCQ and tasks in classification of Sasang constitutions. METHOD: Data were collected from industrial workers in J Province from May 2003 to June 2003. Questionnaires were distributed and collected on the day of their physical examination. Collected data were analysed through chi2-test. RESULT: Health-related characteristics showed that most of smokers and drinkers were Taeumins and this result was statistically significant. Physical symptoms related to constitutions indicated that GI and neurologic symptoms are significantly more frequent in Soeumin. The percentage of subjects with moderate risk was high in order of Soyangin, Taeumin and Soeumin while the percentage of subjects with high risk was high in order of Soeumin, Taeumin and Soyangin. CONCLUSION: Through this study, Lee Jae Ma's theory was be confirmed compatible with disease characteristics. However, research with more various subjects and variables needs to be made.

OBJECTIVE: To analyze the clinical characteristics of obese infertile women. MATERIAL AND METHOD: Height, weight, body mass index, menstrual pattern, glucose, insulin, glucose / insulin ratio, dehydroepiandrosterone sulfate (DHEA-S), testosterone, free testosterone and plasminogen activator inhibitor (PAI-1) of 15 obese infertile women were tested. RESULTS: Of 15 obese infertile women, the number of diabetes mellitus, hyperinsulinemia, and insulin resistance was 2 (13%), 2 (13%), 2 (13%), respectively. The incidence of increased DHEA-S, testosterone, and free testosterone was 7 (47%), 1 (7%), 6 (40%), respectively. Notably, all patients showed increased PAI-1. CONCLUSIONS: Obesity is associated with infertility as well as many kinds of health problems. Obesity is closely related to insulin resistance and it also causes hyperandrogenism. Increased PAI-1 is one of the important causes of thrombophilia. Consequently, in the workup of obese infertile patient, many aspects of health problems should be considered.

OBJETIVE: To analyze the antithrombin III deficiency in patients with recurrent spontaneous abortion. MATERIALS AND METHOD: The blood samples were tested by chromogenic assay to evaluate the activity of antithrombin III. RESULTS: There was only one case of antithrombin III deficiency. This patient experienced one neonatal death after delivery and one FDIU (fetal death in utero). And also this patient showed a lupus anticoagulant and the prolongation of PTT. CONCLUSIONS: Women with recurrent miscarriage who have no obvious identified cause should consider hematologic screening. Antithrombin III deficiency could be a cause of recurrent spontaneous abortion. But the incidence is very rare in Korean patients.

A balanced translocation in a parent may produce unbalanced gametes leading to abortions or defective liveborn children, or interval infertility. It also may give rise to a balanced gamete resulting in a balanced carrier, or it may produce a cytogenetically normal gamete. The incidence of balanced chromosomal translocations in couples with multiple abortions was reported as 0% to 31%. This wide variation is related to the heterogeneous criteria used for patient selection. Because parents with balanced chromosomal rearrangements and history of only repeated abortions have a significant chance with each pregnancy of having a child with normal or balanced karyotype, the usual criteria for investigation include at least two abortions or reproductive losses. There is no evidence from several reported series that increasing the number of losses to three or more leads to any change in the yield of chromosomal rearrangements detected.

Pulsatile secretion of GnRH from the hypothalamus is a prerequisite for both the initiation and maintenance of the reproductive axis in humans. Failure of this episodic GnRH secretion results in the clinical syndrome of hypogonadotropic hypogonadism. Deficient GnRH secretion may occur in isolation (idiopathic hypogonadotropic hypogonadism: IHH), in association with anosmia (Kallmann syndrome), or as a result of a variety of structural and functional lesions of the hypothalamic pituitary axis. The familial occurrence of hypogonadotropic hypogonadism associated with anosmia, color blindness, synkinesia, and mental defect is the classic Kallmann syndrome. Affected individuals respond readily to pulsatile administration of exogenous GnRH, and clearly this is the most physiologic approach to ovulation induction. For women not seeking pregnancy, replacement therapy with exogenous estrogen and progestin is indicated. We have experienced a case of Kallmann syndrome which was conceived by administration of gonadotropin. So we report this case with a brief review of literatures.

Chromosomally derived sterility has long been recognized. A review of the literature of somatic chromosome investigations in infertile males has shown that 13.7% of azoospermic males and 4.6% of oligozoospermic males have an abnormal karyotype. In the first group, sex chromosome abnormalities predominate (mainly 47,XXY), whereas in the latter, autosome anomalies (i.e. Robertsonian and reciprocal translocations) are the most frequent. A similar review on meiotic studies revealed that meiotic chromosome anomalies can explain male infertility in 4.3-40.4% of patients. Recently, fluorescent in-situ hybridization studies on spermatozoa from infertile men were published; it was suggested that both X-Y pairing and pairing of the autosomes were impaired, resulting in spermatogenic disruption. It is estimated that there are 2,000 genes that regulate spermatogenesis, most of these being present on the autosomes, but there are approximately 30 genes on the Y chromosome. In general, autosomal genes that regulate spermatogenesis are concerned with regulation of metabolic processes in other cells in the body as well as in the cells of spermatogenesis, whereas Y genes are not essential for vital functions related to reproduction. To be able to provide proper counseling for those couples whose male infertility can now be treated by intracytoplasmic sperm injection, it is suggested that clinical investigations should include mitotic and meiotic studies, an analysis of the chromosome content of individual spermatozoa and a DNA analysis of blood and spermatozoa to detect partially deleted Y chromosome material. We have experienced a case of azoospermia associated with inversion of chromosome 1. So we report this case with a brief review of literatures.
