In parentage testing DNA profiles are used to link the alleged father with paternity by matching their patterns. The probative value of a match is often calculated by multiplying together the estimated frequencies with which each particular VNTR or STR pattern occurs in a reference population. When this calculating method applies to the motherless case of paternity disputes, a calculation must usually be based on types determined for the child and the alleged father. In such case, the first consideration is to exclude a man from paternity of a child when the man did not have the child's paternal allele at some loci, or if the paternal allele cannot be determined, when the man had neither of the child s alleles. The second is to evaluate the DNA evidence when a man is not excluded by the paternal allele. This work is to provide theories of paternity analysis with three approach methods for the motherless case, and to evaluate their efficiency compared to the trio case when the man tested is not excluded. Consequently, the motherless case offers lower probability exclusion and questionable cumulative paternity index than those of the trio case as being typed with 14 STR loci(CSF1PO, TH01, TPDX, vWA, D5S818, D13S317, D7S820, D16S539, FGA, D21S11, FES/FPS, F13A1, D18S80, D17S5). Since the motherless case in paternity disputes is less efficient for paternity exclusion of the child, the use of genetic maker systems with the higher value of mean exclusion chance(MEC) and exact levels of the relative probability of paternity must be of importance considered in the analysis of such deficiency cases.

PURPOSE: A varicocele is the most common correctable cause of infertility in men. Conventional techniques of varicocele repair are associated with substantial risks of hydrocele formation, varicoele persistence and recurrence. The inguinal approach with classic Palomo technique was used to be simplified the procedure and to get the same good results with the Palomo technique. MATERIALS AND METHODS: From March 1990 to March 1997, we experienced surgical corrections of 54 patients with varicocele(A mean age 20.3 years) The most of patients were left-sided(96.3%). Until March 1996, surgical correction with Palomo(6 patients) and modified Palomo(13 patients) technique by retroperitoneal approach and Ivanissevich techrique(20 patients) by inguinal approach have been performed, and since April 1996, Palomo technique(15 patients) with inguinal approach has been performed, in which the entire vascular pedicle is ligated superior to the entrance of the was deferens through the inguinal incision. RESULTS: The postoperative recurrences in the modified Palomo technique occurred In two of the 13 patients(15%) and in the Ivanissevich technique in three of the 20 patients(15%). But there were no recurrences In the retroperitoneal Palomo and modified inguinal Palomo techniques. The modified inguinal Palomo technique was completed within 45.3minutes in mean duration, but the standard retroperitoneal Palomo technique within 55.2minutes, modified Palomo technique within 57.2minutes and Ivanissevich technique within 51.4minutes. There was no varicocele recurrence, hydrocele and atrophy of testis in modified inguinal Palomo techniques. CONCLUSIONS: The modified inguinal Palomo technique was easily approachable and relatively fast in our experience and had no recurrence.

The HUMACTBP2 locus was investigated to collect population genetic data in the Korean population and to evaluate the applicability for the forensic field. An Automatic fluorescent-based sequencer (377 automatic DNA sequencer, ABI) was used to detect amplified fragments of the HUMACTBP2 locus electrophoresed on 4% denaturing polyacrylamide sequencing gels. ACTBP2 allelic ladder consisting of different sizes of 18 alleles was constructed and employed as an internal size standard in combination with a GS-350 size standard for precision of allele-band sizing. By utilizing different fluorescent dyes, both the allelic ladders and samples were able to be analyzed in the same lane by 99% orecision of allele-band sizing. Among the Korean population (n=224), 26 alleles in the range of 239-313 bp are determined. allele No. 6 is found 45 times (0.100) which is mostly frequent, and the rest of allele is distributed with their relative frequency of 0.002-0.100. The comparison between observed and expected numbers of homozygous and heterozygous individuals confirms that ACTBP2 locus is in the state of Hardy-Weinberg equilibrium among the Korean population. The heterozygosity is 0.9389+/-0.0034(93.89%), and the power of discrimination(PD) and power of exclusion(PEX) are calculated to be 0.991(99.1%)and 0.890(89.0%), respectively, showing the high informativeness for individual identification. Thus, these results mean that the HUMACTBP2 locus can effectively be used for the forensic application.

When we intend to do the personal identification using DNA profiles, it will obviously be better to use as much information as possible. The power of identification is increased by using the genetic marker system such as VNTRs or STRs. Although STRs do not have many alleles per locus as VNTRs, these can be compensated by a large number of loci that are potentially usable. However, it will be more efficient to use a morphic loci. Therefore, prior to choose the genetic marker system of STRs for identification, it is essential to consider the statistical parameters of each STR locus, such as obs-H(observed heterozygosity), exp-H(expected heterozygosity), pM(probability of match), DI(discrimination index), PD(power of discrimination), MEC(mean exclusion chance), MEP(mean exclusion paternity), PIC(polymorphic information content) et al. In this article, we described the exact meaning of statistical parameters for the purpose of identification.

Allele-and genotype frequencies of the two short tandem repeat (STR) loci, HumFGA and D21S11, were determined in Korean population(n=196). DNA typing was accomplished by applying fluorescence-labeled PCR products and a differently labeled sequenced allelic ladders, followed by automated analysis using ABI 377 automatic sequencer and GeneScan 2.02 software. Prior to typing, allelic ladder of each locus was constructed with a combination of all alleles occuring from the population sample. A total of 15 alleles and 48 genotypes with the heterozygosity of 0.854 for HumFGA, and 12 alleles and 33 genotypes with the heterozygosity of 0.787 for D21S11 are observed in a population of 196 genetically unrelated individuals. No deviations from Hardy-Weinberg equilibrium were observed(p=0.753 for HumFGA, p=0.262 for D21S11). The data presented here (power of discrimination and average power of exclusion) show that both STR Loci, HumFGA and D21S11, are very informative for individualization from criminal evidences, and are also useful for parentage testing.

The p53 gene product has been detected in various human tumors. To investigate the overexpression of the p53 protein in bladder tumor as a marker of tumor progression, the correlation between the overexpression of the p53 protein in bladder and the pathologic grade, stage and survival rate was studied. Among specimens of 47 patients, 19 were from patients of superficial bladder tumor, 28 were from invasive bladder tumor according to pathologic stage, while 15 were from low grade and 32 were from high grade tumors according to Ash grade p53 overexpression was determined by immunohistochemistry using DO-7 primary antibody on paraffin embedded sections and flow cytometry was performed on cell suspensions derived from the same blocks. Histologically normal bladder tissue was used as a control group Conclusions were made as follows: 1. p53 protein overexpression was observed in 31 of 47 cases(65.9%). 2. Seven of 15 specimens from well differentiated tumor(Ash grade I, II) showed positive p53 staining while 24 of 32 cases from poorly differentiated tumor (Ash grade III,IV) showed positive staining. There is a significant correlation between p53 expression and poor pathological grade(p=0.05). 3. Nine of 19 cases with superficial bladder tumor showed positive staining while 22 of28 cases of invasive tumor showed positive staining. There is a significant correlation between p53 protein overexpression and invasive tumor(p=0.027). 4. Flow cytometric examination revealed that 24 of 30 cases with aneuploid group showed positive staining while 7 of 17 cases with diploid group showed positive staining. Aneuploid group showed high correlation with p53 protein overexpression(p=0.007). 5. The survival rates of patients, exhibiting p53 protein overexpression, were slightly worse than those with p53 negative tumor(p=0.08, Wilcoxon test) but this difference was not significant enough to count. 6. p53 protein overexpression was well correlated with grade, stage and flow cytometric analysis in bladder tumor. 7. Multiple linear regression study to survival rate showed the overexpression of p53 protein had little prognostic significance in bladder tumor compared with tumor grade and stage.

Allele designation for HumACTBP2 is not yet established while many authors introduced different kinds of designation methods. Here, we are introducing a new allele designation method. We used allelic ladder as an internal size standard on behalf of GS-500ROX and designation of each allele was followed recommendation of DNA commission of International Society of Forensic Hematogenetics(ISFH). This method is considered more reasonable for complex repeat loci like HumACTBP2 than other methods that published before.

The hypervariable short tandem repeat (STR) locus D12S391 was investigated in a Korean population. A total of 14 alleles were detected by size under denaturing conditions in 517 unrelated individuals. To confirm all of the alleles detected in a Korean population, a total of 34 fragments were sequenced. Prior to allele designation, we constructed the allelic ladders containing 11 alleles sequenced in this study. Allele 18 is the most common with a frequency of 0.281 in Koreans, and one variant allele 19.3 which have been confirmed by sequencing, was detected. The observed heterozygosity, the power of discrimination (PD), and the mean exclusion chance (MEC) for the locus D12S391 is 0.781, 0.946 and 0.652, respectively. No deviation from Hardy-Weinberg equilibrium was observed in a Korean population (p=0.557). In the 424 meioses in 105 Korean families confirmed using other 17 STR loci, no mutation was detected in locus D12S391. The STR locus D12S391system is useful both for the analysis identification and parternity.
