{"title":"[Forensic DNA analysis--past and future].","authors":"H Fukushima","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Since the introduction of DNA polymorphism analysis techniques to forensic science, forensic identification research has made radical, astonishing progress at a rate that has already rendered the initial methodologies introduced fifteen years ago obsolete. DNA extraction now can be quickly and efficiently performed by various kinds of commercially available kits. The advent of PCR has enabled the use of relatively crude and minute DNA as amplification templates while many kinds of new detection methods for analyzing the amplified products have also been developed. Although many minisatellites such as MCT118, YNZ22, COL2A1, and ApoB were highlighted at the beginning of 1980s, none of these loci, with the exception of MCT118, have proved useful for forensic DNA application due to their low amplification efficiency. On the other hand, STR loci containing four base pair repeat sequences have been used routinely for human identification since the mid-1990s. In the near future, the highly efficient STR should be selected as a consensus core marker in Japan. STR systems located on the Y chromosome are widely used in forensic science for the identification of male individuals. These systems have a special significance in forensic science cases where mixtures of male and female DNA are analyzed, as happens in cases of rape or other sexual crimes. The characteristics of high copy number, maternal inheritance, and high degree of sequence variability make mtDNA a powerful tool for forensic identification. Most of the variations in mtDNA among individuals are found within the displacement loop (D-loop). In all population groups, mtDNA sequences can be useful for discriminating among unrelated individuals. Now it is necessary to get as much as possible individual genetic information as quickly as possible in order to enable individual identification. We will create a new era in which forensic identification can be performed using microarray technology.</p>","PeriodicalId":19215,"journal":{"name":"Nihon hoigaku zasshi = The Japanese journal of legal medicine","volume":"53 3","pages":"276-84"},"PeriodicalIF":0.0,"publicationDate":"1999-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21575409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[Biological actions of acetaldehyde].","authors":"I Ijiri","doi":"","DOIUrl":"","url":null,"abstract":"&lt;p&gt;&lt;p&gt;Acetaldehyde (AcH), the first metabolite of ethanol (EtOH), is a chemically reactive and pharmacologically active compound. The author has been engaged in the study of AcH in cooperation with many researchers for three decades. We have found many biological actions of AcH which cause cardiovascular symptoms after drinking and also inhibited EtOH absorption via the canine and rat intestinal tract. This report covers the following five points. 1. The subjects were classified into a non-flushing group and a flushing group, according to the degree of facial flushing after drinking 200 ml of Sake (Japanese rice wire) at a rate of 100 ml per 5 min. Blood EtOH profile was much the same in both groups, yet peak blood AcH concentration in the flushing group was significantly higher than that in the non-flushing group. All subjects in the flushing group showed marked flushing and an increase in pulse rate after drinking, but these symptoms were not apparent in the non-flushing group. These results suggested that cardiovascular symptoms were caused by AcH itself. 2. Urinary excretions of both norepinephrine and epinephrine increased in the flushing cases after drinking Sake in comparison with those who drank the same volume of water. However, these catecholamines did not change in the non-flushing group. These results suggested that it is catecholamines released from the sympathetic nerve end or the adrenal medulla by AcH which caused an increase in pulse rate. 3. Bradykinin is released from high molecular kininogen by activated kallikrein and acts to dilate distal blood vessels and raise permeability in tissues. On the other hand, kallidin is released from low molecular kininogen by activated glandular kallikrein and its action is weaker than that of bradykinin. Blood low molecular kininogen levels in the flushing group decreased gradually after drinking and were mutually related to the blood AcH concentrations. But levels in the non-flushing group showed no difference before and after drinking. The decrease in low molecular kininogen levels indicates that kallidin released from glandular kallikrein exists in the glandular tissues such as the kidneys, sweat glands, saliva glands, etc. We hypothesize that kallikrein activated by AcH in the sweat glands produces kallidin which cause vessels around the glands to dilate, and flushing of the face and the whole body occurs due to escalation of the sphere of dilatation of blood vessels. 4. A isolated 30 cm length of the canine jejunum segment with intact vascular supply was performed. After pretreatment with cyanamide (CY), a potent inhibitor of aldehyde dehydrogenase, or pyrazole (PY), a potent inhibitor of alcohol dehydrogenase, a 17% EtOH solution (0.4 g/kg) was administered into the jejunum segment, and 150 min after the administration of EtOH, the fluid from the segment was collected to determine its volume and EtOH concentration.
