The ultrastructural indices of the morphofunctional state of the heart in acute and chronic alcoholic intoxication

Morphofunctional myocardial characteristics in subjects who died of acute and chronic alcoholic intoxication were studied at ultrastructural level. The resulting new data enhance the level of diagnosis concerning the cause of death, the grounds of thanatogenesis. Possibilities for using the results of investigation in scientific and practical work are shown.     

The forensic medical characteristics of the injuries to the spleen in blunt trauma of the abdomen

Analysis of 220 sectional cases with blunt spleen trauma is given in this article. Trauma circumstances, morphologic features of spleen injuries depending on the kind of blunt trauma, mechanism of their formation were studied.     

A modified Gustafson method of age estimation from teeth

Modifications to the Gustafson method of age estimation from teeth are described. They are designed to minimise the subjective nature of the scoring technique and to quantify the regressive changes in the enamel, dentine and cementum. Randomly selected teeth from 25 Indians were examined by the Gustafson method and by our own modification. It was shown that our modified method resulted in more accurate and reproducible age estimations than did the original method.     

The forensic significance of conjunctival petechiae

Conjunctival petechiae were mentioned in 227 (4.5%) of 5,000 consecutive autopsy reports of the Dade County Medical Examiner Department. They were most frequently observed in those who had died natural deaths (particularly due to cardiovascular disease), followed by those who had died from asphyxia, head injury, and central nervous system disorders. The incidence of conjunctival petechiae in victims of homicidal asphyxiation was 78%. These data suggest that conjunctival petechiae most often are the result of hypoxia coupled with an acute increase in cephalic vascular pressure. The latter factor may be the consequence of mechanical vascular obstruction or acute right heart failure.     

The morphology of the gunshot entry wound

The main signs of inlet gunshot wound inflicted from non-close shot distance are the following: central defect of the tissue, presence of abrasion and rub zones along the margins. During experimental study high variability of these signs was stated and new morphologic characteristics of inlet gunshot wound were detected.     

Use of histoelectrofocusing in the determination of PGM1 subtypes in human body tissues

The present study reports the successful application of histo-electrofocusing to the determination of PGM1 subtypes in various tissues of the human body. The method described here is of practical use in individualizing parts of cadavers stored for up to 1 week.
