The polymorphism of plasminogen (PLG) by ultrathin-layer isoelectric focusing. Distribution in the Veneto population (Italy)

The distribution of plasminogen phenotypes in the population of Veneto was investigated by ultrathin-layer isoelectric focusing. In our sample (n = 1325), the three common phenotypes PLG1, PLG2, PLG2-1 and two further phenotypes PLG1-V and PLG2-V were, observed and the following frequencies calculated: PLG1 = 0.84038; PLG2 = 0.15811; PLGV = 0.00151. These gene frequencies are compared to those found in other populations. Analysis of 41 mother-child pairs was in agreement with an autosomal codominant inheritance.

Paraquat (gramoxone) poisoning in south-west Hungary, 1977-1984. Toxicological and histopathological aspects of group intoxication cases

Fifty-six cases of paraquat poisoning were examined during the 8 years 1977-1984. The ratio of cases of accidental to intentional ingestion of the poison was 1:1; 23.2% of the total (13/56) survived several months or years. In 1983, 11 subjects accidentally drank 10-30 ml of gramoxone; eight of 11 died in 2 weeks. Toxicological investigations demonstrated rapid elimination of poison from the blood, as well as prolonged fixation of paraquat in the lung, kidney, liver, and spleen tissues. Histological examinations showed multiorgan failure from renal tubular necrosis and pulmonary hemorrhage with alveolar epithelial injury. Pulmonary proliferative changes were present in only two cases who survived 7 and 10 days and in which artificial ventilation was utilized.     

An exceptional case of necrophilia

The authors describe a case of necrophilia in which the corpse of a young girl was disinterred. No lesions were observed on the genitals and breasts, but the aspect of the anus suggested that some object had been introduced in it. The possible modalities of the event are discussed.     

从沙尘暴防治看立法理念的转换

近年来沙尘暴事件频繁发生、社会危害严重,引起全社会的高度重视.我国颁布实施的《防沙治沙法》以防沙治沙为目的、被预期能直接应对沙尘暴,但法律治理效果甚微.这需要我们反思环境立法理念.从源头上看,沙尘暴的表现形式为自然灾害,但人类对自然界的严重破坏行为是原因的主要方面.因此相应的立法理念、思路和重点就必须重在对于人的行为进行控制,需要治沙但更为重要的是在立法中引入人地协调的理念.理念的转换带来相应的制度的完善,解决现有的防沙治沙的问题、实现其立法目的,其根本上还要在防沙治沙法中突破原有单项思维模式,引入综合决策方式.     

Isotope ratio mass spectrometry as a tool for forensic investigation (examples from recent studies).

The versatility of isotope ratio mass spectrometry is demonstrated by reference to diverse case studies. Variations in the natural isotopic composition of non-biological, organic materials are compared as a means by which samples may be associated or discriminated. These techniques may be used to augment or compliment conventional forensic methodologies. delta13C analysis was used to demonstrate that different masking tape had been recovered in two, apparently similar cases, involving the smuggling of money. Visually similar ecstasy tablets were compared by consideration of the delta13C and delta15N composition of MDMA extracted from the tablets. Although only a limited number of tablets were analysed, the isotopic similarity between two different seizures was sufficient to induce a guilty plea from a person suspected of possessing both. A combination of delta2H, delta13C, delta15N and delta18O together with GC-MS analyses were applied to small samples of seized heroin. Although GC-MS analysis indicated differences between the chemical composition of two of the heroin samples, isotopic analysis suggested similarities, which were confirmed by further delta2H, delta13C and delta18O isotopic analysis of the clingfilm in which the samples were wrapped.
