The cannabinoid content of 13 different strains of cannabis plant (Cannabis sativa L.) was analyzed. Six strains fell into the "drug-type" class, with high Delta-9-tetrahydrocannabinolic acid (THCA) content, and seven strains into the "fiber-type" class, with low THCA using HPLC analysis. Genomic DNA sequence polymorphisms in the THCA synthase gene from each strain were studied. A single PCR fragment of the THCA synthase gene was detected from six strains of "drug-type" plants. We could also detect the fragment from seven strains of "fiber-type" plants, although no or very low content of THCA were detected in these samples. These were 1638 bp from all 13 strains and no intron among the sequences obtained. There were two variants of the THCA synthase gene in the "drug-type" and "fiber-type" cannabis plants, respectively. Thirty-seven major substitutions were detected in the alignment of the deduced amino acid sequences from these variants. Furthermore, we identified a specific PCR marker for the THCA synthase gene for the "drug-type" strains. This PCR marker was not detected in the "fiber-type" strains.  相似文献

The term ‘intersectionality’ recognises the need for a ‘holistic approach’ in the determination of the right to be free from discrimination and violence. While the European Court of Human Rights has never expressly used the term, this article argues that the recent case of B.S. v Spain provides an example of a more robust use of Article 14 of the convention taking into account the real life experiences of those facing intersectional discrimination. The decision recognising the special vulnerability of a migrant, female sex worker is therefore both welcome and necessary.  相似文献

图们江地区开发项目自1990年提出并启动实施以来,经过十几年的发展,东北亚各国的交流已取得了实质性的进展.特别是2005年东北亚各国提出的大图们江地区开发与中国吉林省提出的"长吉图开发先导区"构想的结合,将使图们江地区的现代化、国际化走向一个全新的阶段.目前,该地区的基础设施建设已有了长足的进步.为了进一步促进东北亚各国的经济交流与合作,增强图们江地区运输走廊的活力,中蒙铁路的建设成为一个需要解决的现实问题.当今世界范围内的金融危机使该项目的实施受到一定程度的影响,但面对未来逐步扎实地推进是非常重要的.  相似文献

The myoglobin content of heart muscles was examined by the indirect immunoperoxidase method in eight autopsy cases where death was due to electricity. Seven cases showed a considerable release of myoglobin from the myocardial fibers. In experimental comparison, the heart muscles and skeletal muscles from nine cases where death was natural were exposed to electricity, and considerable deletion of myoglobin was also demonstrated. We believe that the findings of ischemia or thermal effects due to electricity were the cause of the release of myoglobin. Because the demonstration of myoglobin is preferable to estimation of the damaged areas of muscles by hematoxylin-eosin staining, this examination may be more advantageous in forensic examination of death by electricity.  相似文献

The inhalation of automobile exhaust gases is a relatively frequent suicidal method. Two such cases of special interest to forensic pathology and toxicology have been introduced. In case 1, a suicide note disclosed the victim's mental state, the inside conditions of the car, and toxic effects of automobile exhaust. In case 2, a reconstruction experiment has revealed important factors for the investigation of the scene, such as the size of a vinyl hose, the conditions of connecting site of the hose with the exhaust pipe, etc.  相似文献

Myocardial lesions induced after trauma and treatment.   总被引:1,自引:0,他引:1  
In order to clarify the effect of trauma and treatment as stresses on myocardia, we examined histological changes of myocardia in victims who received various kinds of traumata and treatments. We also undertook a histochemical study for calmodulin, which we found useful in the diagnosis of early ischemia. Those who died shortly after stab wounds, traffic accident or head injuries, showed mild cardiac lesions such as contraction bands or fragmentation and mild diffusion of calmodulin, a marker for necrosis. A case with hemorrhagic shock after a traffic accident, involving intense resuscitation for 2 h, showed severe cardiac lesions such as contraction bands, hydropic change and subendocardial hemorrhage along with severe diffusion of calmodulin. In most of the instant death cases after falls, severe contraction band necrosis and severe calmodulin diffusion were observed. Myocardia of victims, who died several days after head injuries or traffic accidents, generally demonstrated distinct diffusion of calmodulin as compared to the mild and non-specific lesions detected by hematoxylin-eosin (H&E) staining. In cases of long-term survival in a state of brain death, calmodulin staining was very low, which was not always associated with the severity of the lesions on H&E staining. In cases with intensive or extended treatment, it appeared to be difficult to determine the cause-effect relationship between trauma and cardiac lesions or to distinguish the lesions due to extrinsic factors from those of disease. In some cases, calmodulin intensely stained the areas with hydropic appearance or hypereosinophilia, which may be related to calcium overload.  相似文献

Sex determination of blood stains from women who were in the late stages of pregnancy was possible by detecting human placental lactogen (HPL) in them. However, the agglutination time for positive reactions was prolonged as the stains aged.  相似文献

The rudimentary horn is a rare developmental anomaly of the Müllerian duct. Ectopic pregnancy in the rudimentary horn is estimated to occur in one out of 76,000–150,000 pregnancies. A 30-year-old primigravida suddenly collapsed after 3 days of continuous abdominal pain. Emergency laparotomy revealed a massive intraperitoneal hemorrhage and fetal demise. The growth of the fetus after 19 weeks of gestation is believed to have caused the rudimentary horn rupture, thereby rapidly leading to hemorrhagic shock in the mother and ischemic death in the fetus. This is the first autopsy report on maternal death due to the rudimentary horn or other Müllerian duct anomalies, which emphasizes the need for forensic pathologists to consider this condition as a possible cause of unexpected death in fertile women. In addition, it is very important for clinicians to detect Müllerian duct anomalies by sonography during routine obstetric examinations, and promptly diagnose anomaly related ectopic pregnancies in women displaying symptoms of an acute abdomen, intraperitoneal hemorrhage, or shock in the emergency practice.  相似文献

A young woman committed suicide by ingesting benzine. We report the findings obtained at autopsy and the chemical analyses of the gastric contents, blood, and tissues in this case. Fatal concentrations of n-hexane, benzene, toluene and m-, p-xylene were detected. Pulmonary edema and hemorrhage were caused by the primary effect of the chemicals or secondarily by respiratory depression, suffocation due to volatile fluid, or heart failure. Mild hemorrhage around arterioles and venules in the brain cortex suggest hyperpermeability of the vessels. The fragmentation and waviness of the cardiac myofibrils indicate the presence of hypercontraction and possibly arrhythmia.  相似文献
