An appraisal of plastic reconstruction of the external nose   总被引:1,自引:0,他引:1  
The association between the morphometric dimensions of the external nose, including the thickness of the soft tissues, and various craniometric measurements has been examined on a sample of lateral radiographs of 154 males and 199 females from Vienna, Austria. In addition, the influence of age on morphometric dimensions and the soft tissue cover was tested. Multiple stepwise regression analysis revealed that nasal height and nasal length are best predicted by the dimensions of the skull, whereas nasal depth and the thickness of the soft tissues is greatly influenced by age. In males, over 50% of the variance of nasal height and nasal length were accounted for by the height of the bony nose and the prominence of the ossa nasalia, and in females it was about 40%. Although the thickness of the soft tissue is dependent on exogenous factors, such as nutrition, mimicry, and so forth, the dimensions of the bony nose apparently also influence the skin depths to some extent. High and prominent noses were found to have a thinner layer of soft tissue over the nasal bones than short and less prominent ones. It thus seems as if there is a tendency of the soft tissue cover to adjust to disharmonies of the bony profile.  相似文献

The external male genitals (EMG) of male corpses, who abused alcohol and narcotics at lifetime, were examined. The objects were stained according to the common histological and histochemical methods. The study results are indicative of a high frequency rate of pathologic changes of the EMG in persons, who abused alcohol and narcotics at lifetime. The inflammatory, fibrosing and atrophic changes of the EMG as well as a reduced vascular permeability can be a cause for erection malfunction.  相似文献

Characteristic changes that can be demonstrated on roentgenograms occur with increasing age in the plastron (chest plate) of humans. These alterations include progressive ossification in the costal cartilages (located characteristically in the sternal rib end, centrichondrally, and peristernally--often with sex and age distinctive patterns), maturation of the newly formed bone with trabeculation formation, loss of the smooth contour of the costo-manubrial junction, cupping of rib ends, osteoporotic changes, and arthritic changes in the sternal head of the clavicles. The sequence of development of these alterations has been examined by X-ray of 1965 cadavers of 15 years of age or over and correlated with the gross bone and cartilage morphology changes in many cases. This technique allows for age determination within 5 years of real age in 55% of cadavers and within 25% of real age in 95% of all cadavers. The greatest departures from real age are in the over-60-year groups. The same roentgenograms can allow for correct sex prediction in 99% of the population.  相似文献

In an earlier study, we unexpectedly found that defendants charged with sex crimes were four times less likely to be convicted than were all other defendants. We now report that failure to convict for rape was associated with failure to come to trial and that minor sex crimes were tried, but often continued without a finding, even when the judge found sufficient facts to make a guilty finding. Whether a minor crime involved a victim and whether the defendant has a criminal record both relate to verdict, but psychiatric history did not. The implications for understanding "acquittal of the guilty" are discussed.  相似文献

To determine the time-course of human subcutaneous hemorrhage, heme oxygenase (HO)-1 expression and macrophage infiltration were observed using an immunohistochemical technique and semiquantitative analysis. The number of immunoreactive cells and the number of all infiltrating cells of each microscopic field were counted, and the ratio of the former to the latter was calculated as the positive cells ratio. An increase in the HO-1-positive cells ratio was observed starting at 3 h after injury, and the maximum ratio was observed 3 days after injury. The pattern of the increase in the macrophage ratio was similar to that of the HO-1-positive cells ratio in the early period after injury. Observation of serial sections revealed that the expression of HO-1 in the cells corresponded to the localization of macrophage. The present results suggest that the determination of HO-1 expression, as derived from macrophages, might be useful for the estimation of the time-course of subcutaneous hemorrhage.  相似文献

Four monoamine metabolites, 3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA), 3-methoxy-4-hydroxyphenylglycol (MHPG) and 5-hydroxyindoleacetic acid (5-HIAA), were determined in the cerebrospinal fluid (CSF) of cadavers, whose causes of death had been suicidal hanging (SH) or ischemic heart failure (IHF). The concentration of DOPAC increased in parallel with the increment of the postmortem interval (PMI) (r = 0.626), whereas the concentrations of HVA, MHPG and 5-HIAA did not. The correlation coefficient was further increased by considering each cause of death separately: i.e., SH, r = 0.761; IHF, r = 0.705. These findings suggest the possible usefulness of the DOPAC level in CSF for estimating PMI.  相似文献

Conclusion In light of the historical context in which the visit of the United States delegation took place, the emphasis was on the political abuse of psychiatry. It should be clear, however, that the repression of dissidents is only the most visible manifestation of a system of psychiatric control that has been, and continues to be, profoundly insensitive to human rights. Although some tentative steps have been taken to subject coercive psychiatry to the rule of law, these limited initiatives have not yet become operational. Implementation of the legal reforms recommended by the delegation would help to reduce the likelihood that the pattern of psychiatric repression will reemerge. But the proposed reforms have a larger purpose—to assure that the practice of psychiatry in the Soviet Union is properly respectful of fundamental human rights, whether or not the patients have engaged in political or religious dissent.This is a revised and expanded version of the Fifth Samuel and Kathryn Yochelson Lecture, delivered at Yale Law School, New Haven, Connecticut, U.S.A., September 28, 1989, and of a paper presented to the Second International Conference on Health Law and Ethics, London, England, July 21, 1989, which paper was reprinted in 18Law, Medicine, and Health Care 123 (1990).B.A., Johns Hopkins University 1966; LL.B., University of Virginia 1969. The author was one of two lawyers who served on an official United States Department of State delegation that visited the Soviet Union (February 26–March 12, 1989) at the request of the Soviet government to assess recent changes in psychiatry there. The U.S. delegation was led by Loren H. Roth, M.D., M.P.H. (psychiatric team leader) and Daniel A. Regier, M.D., M.P.H. (scientific director).This article summarizes the delegation's findings and, in so doing, draws heavily on its report, which was drafted by the delegation as a whole. However, the opinions expressed in this article are the author's and should not be attributed to the delegation.  相似文献

Cytochrome c oxidase (COX), a mitochondrial enzyme, is inactivated by cyanide or carbon monoxide (CO) intoxication. To test whether cytochrome c has potential as an indicator of these toxins in cadavers, we measured COX activity in the main organs of the rat, and in the human heart, at various times after death. Each tissue sample or organ was homogenized and the COX activity in the mitochondrial fraction was measured using ferrous cytochrome c as the substrate. COX activity was significantly higher in rat brain, heart and kidney than in lung and liver from 0 to 4 days after death. The loss of COX activity was significantly slower in the brain and heart than in the lung, liver and kidney. Most importantly, COX activity correlated with the time-since-death for each of the rat organs we tested (r2=0.70-0.95), but for the human heart (r2=0.47). It may be possible that COX activity is likely to be a useful indicator of the time-since-death, and is worth pursuing as an indicator of the tissue cyanide and CO content.  相似文献

Legal theory and scholarship are currently characterized by a division between traditional, doctrinal methods and approaches derived from extra-legal disciplines. This paper proposes a different though related distinction between two methods of understanding law and interpreting authoritative legal texts.Internal method reflects the viewpoint of the participant in a legal system and traditional doctrinal study; it is practical and decision-oriented. Limitations on the range of arguments and interpretations employed are accepted in order to render its results serviceable for practical tasks.The purposes of external method are cognitive and theoretical; it is oriented toward a comprehensive philosophical and scientific rationality. Its premises and results are therefore not restricted by received professional opinion or social or institutional restraints, and may reflect the conceptual resources of extra-legal disciplines.The paper discusses the antecedents of these methods, describes the structure of each and relations between them, and suggests that the criterion of internal method is practical effectiveness, that of external method truth or falsity.  相似文献

Only two types of human hair roots (proximal ends) derived from decomposing scalps are reported in the literature. The most common representation of the putrid root includes a postmortem dark root band in published photomicrographs. In this study, 22 cases were reviewed in which there was reliable time of death documentation from medical investigator reports. A review of these cases finds that the most common putrid hair proximal end change does not contain the postmortem root band. Four primary types of hair proximal end postmortem change were identified. This study finds no correlation of time of death with scalp hair proximal end decomposition. In addition two examples are presented that suggest that hair roots do not decompose after fresh removal from the scalp and exposure to the outside elements.  相似文献

Presented in this paper are the initial results involving the use of the nose or outer ear as temperature measurement sites to determine the postmortem period of the human corpse. Simple mathematical models for both sites are developed based on cooling curves of five corpses. Analysis of errors between actual and calculated postmortem intervals suggest that in its present form, the described methods would not be suitable for use in accurately determining the time since death of human corpses.  相似文献

A preliminary study has been undertaken to test the individuality of human ear patterns and its probable use in profile view facial image recognition. Anthropometric measurements on 12 inter-landmark linear distances have been carried out for both left and right ears of 700 male and female individuals. A 12-dimensional feature space has been framed to represent each ear pattern as a feature vector with the measured inter-landmark distances as its components. The Euclidean distances in such a feature space amongst all possible pairs of ear patterns of both male and female individuals have been computed. Very few pairs have distances which fell below the safe distinction limit. The undistinguished pairs were further examined by direct superimposition of their images. None of the ear patterns is found to be exactly the same in morphology to the other. Even the left and right ears of the same individual are not identical. Thus, the present study reconfirms the individuality of ear patterns. For establishment of identity, a questioned profile view facial image can be compared with a control one on the basis of the ear pattern visible in it.  相似文献

The possibility of using the data of quantitative microscopy of bone tissue for evaluation of age with the aim of personality identification is discussed. Computer histomorphological analysis of third rib, tibial lower epiphysis and diaphysis fragments from 564 male corpses of known age (0-90 years) was carried out. A complex of parameters most strongly correlating with age was detected: extension of active osteogenesis zone in the longitudinal section of a rib, thickness of layers of internal and external general diaphyseal laminae in the tibial bone, trabecular area in the tibial epiphyseal preparation, etc. Age-specific changes in bone tissue structures is characterized by a great variety and depends on the type and location of these structures. Bone tissue characteristics change irregularly and asynchronously, therefore their correlations with age are different in different age groups. A general biological interpretation of the results is offered.  相似文献

This study deals with issues of research with human embryos obtained through in vitro fertilization in the context of the Spanish Law. The paper focuses on Act 14/2006 on techniques of human assisted reproduction, which replaces the previous Act from 1988. The author claims that the main goals of Act 14/2006 are, on the one hand, to eliminate the restrictions affecting research with human embryos put in place by Act 45/2003 and, on the other, to pave the way for a future legislation on biomedical research. This paper argues for the need of an effective and adequate juridical protection of human embryos obtained in vitro according to responsibility and precautionary principles.  相似文献
