[Population genetics of the D1S80 system in a Central Poland region].

Population data concerning the D1S80 system based on the analysis of 775 persons from Central Poland region was presented. Accordance with the Hardy and Weinberg equilibrium (HWE) was proved using two different statistical approaches. The parameters for the appropriateness of this marker for investigations in the analysed population was also assessed: heterozygosity--0.79, PIC--0.77, PD--0.93, PE--0.62, PI--12.8 and frequency of mutation events--0.27%.

[Sobriety testing in case of lack of cooperation of the examined person--the legal basis of the physician's activities].

The legal aspect of blood sample taking for alcohol concentration from suspicious, uncooperative persons is described in this paper. The Polish law allows for a possibility to take blood samples for alcohol concentration from suspects only by a physician or another skilled medical worker and only when consent is given to the medical procedure. The traffic act makes an exception for cases when the suspects are drivers and the suspicion concerns driving under the influence of alcohol. Taking blood samples is the medical worker' obligation in accordance with the law. The physician can refuse to do this only when the procedure threatens the life or health of the suspect.

[New Polish regulations regarding accidents in the workplace].

With the new year 2003 the new Polish "Law on Social Security Insurance in case of Workplace Accidents and Occupational Illness" came into force, which annulled the previous "Law on Benefits in case of Workplace Accidents and Occupational Illness", dating from 1975, together with its executive provisions, which contained as an Appendix a table for determining the percentage of health loss in a given case. This article, comparing the previous and current laws, analyzes their influence on the process of delivering certificates in legal medicine. In the area of direct interest to the legal medicine practitioner there is practically no difference caused by the introduction of the new law, but because of the lack of executive provisions to the new law, the former directive concerning the principles and mode of issuance of loss-of-health certification, including the health loss percentage table, will continue to be applied.

[Evolution of Supreme Court settlements relating to DNA evidence in paternity investigations].

The evolution of Supreme Court settlements relating to DNA evidence in paternity investigations was presented in this paper. It was found that its opinions have essentially changed during the last years as follows: 1) superiority of DNA evidence over other proof was perceived by the possibility of positive paternity confirmation, 2) attention has been turned to advisability of statistical analysis and its possible positive influence on emotional ties between parents and child, 3) opinion has been expressed about crossing of borders of free judicial estimations in cases of questioning DNA expertise, 4) attention has been turned to the possibility of utilisation of other tissues than blood or indirect genotyping.

[Myocardial infarction as a work accident in Polish Supreme Court decisions. Part I. Excessive stress at work].

This paper deals with Polish Supreme Court opinions on the acceptance of myocardial infarction as work accident. From them the principle emerges that excessive physical or mental work stress can be accepted as the external cause of myocardial infarction in an employee, whereby the excess strain should be judged in each case individually and with reference to the individual situation.

[Myocardial infarction as a work accident in Polish Supreme Court decisions. Part II. Job contraindications due to an employee's state of health].

This paper presents the second part on opinions given by the Polish Supreme Court on the acceptance of myocardial infarction as work accident. This it can be seen that, in certain cases, the judgements of the Court are contradictory. For in some cases, an external cause is recognized in the act of permitting employees to work whose state of health would contraindicate the performance of their duties, while in others, the principle is accepted that work duties not considered harmful for healthy people cannot be deemed an external cause for people with health problems. An external cause according to the Supreme Court may also be the act of allowing an employee to work without a valid medical examination, or even by not conducting routine required work-related medical examinations on time.

[Selected alcohols on the pro- and anti-oxidative processes in rat erythrocytes].

In forensic medicine practice poisonings are rather frequent, and among them, those caused by fatal "substitution" of ethyl alcohol. One of the most frequently encountered "substitutes" for ethyl alcohol is methanol. The purpose of our research was to determine the concentration of malonic dialdehyde as the expression of lipid peroxidation and antioxidant enzyme activity after dosed chronic ethyl and methyl alcohol intoxication. The experiment was conducted on approx. 6 month-old male inbred Lewis rats each weighing approx. 250 g. Ethanol and methanol solution was given in the concentration 1.0 M. The control group of rats received water. Each experimental group numbered 30 rats, this number was divided into three sub-groups, which were put-down at 4, 8 and 12 weeks. The activity of superoxide dismutase (CuZu-SOD) was determined by the Misra-Fridovich method, catalase (CAT) by the Beers-Sizer method. The concentration of malonic dialdehyde (MDA) was determined using the method of Placer et al. by assessing the concentration of TBARS compounds. Results are expressed as a mean +/- SD. The paired Student's test for small groups were used. Superoxide dismutase SOD1 activity decreased compared with the control group throughout the duration of the experiment from 2212 U/gHb to 1676 U/gHb for ethanol and from 2212 U/gHb to 945 U/gHb for methanol. Catalase activity for methanol decreased from 9.1 U/gHb to 5.1 U/gHb, for ethanol to 7.4 U/gHb. In the 4th week of the experiment increase of malonyl dialdehyde concentration for methanol group was observed--from 0.14 umol/gHb to 0.34 umol/Hb; after 8th weeks it decreased to 0.2 umol/gHb and in the 12th week increased to 0.23 umol/gHb. For ethanol these changes was less visible and reached the level of 0.24 umol/l. The statistical processing of the results was performed on the basis of parametric tests (the t-Student test for small experiments) and computer software Statistica. The statistical significance was set for p<0.05.

[Long-term realistically life-threatening disease].

In this paper the authors discuss a legal code description of a wrongly included (as a result of a legislative error) "long-term really life-threatening disease" (dlugotrwala choroba realnie zagrazajaca zyciu) in the Criminal Code. This category of disease impossible to apply in practice since its terms "long-term" and "realistically life-threatening" are mutually exclusive--is nonetheless applicable to crimes committed from Sept. 1, 1998 to Dec. 8, 2003. In effect this causes a change in the qualification of certain acts in Art. 156 of the Criminal Code, to include those in Art. 157, Paragraph 1, and in some cases, even extending to acts named in Art. 157, Paragraph 2 of the Criminal Code.

[Malpractice in internal medicine in the case material of the Forensic Medicine Department, Medical University of Lódź, Poland].

Legal opinions in the area of internal medicine, opinionated by the Forensic Medicine Department, Medical University of Lódź, Poland in 2002, were selected for further analysis and assessment in the course of medical treatment. During this period opinions were given in 20 cases, most of which concerned cardiovascular, secondly respiratory, followed by, endocrine diseases. In half of the cases analyzed it was determined that medical treatment had been incorrect. All of the objectionable diagnostic and therapeutic procedures evidenced some form of decisional error. In most cases errors were made in the diagnosis, as a result of neglect in performing necessary examinations, or of erroneous interpretation of results obtained.

[Changes of the concentration of lipid peroxidation products and thiol groups in rat brains with long-term intoxication with methanol].

The aim of this paper was to define the influence of long-term methanol intoxication on the changes of end products of lipid peroxidation, reacting with thiobarbituric acid (TBA-reactive products) and free SH-group concentration in rat brains. The experiment was conducted on male Lewis rats. The experimental groups received a 1-molar methanol solution and the control group received tap water. The animals were killed after 4, 8 and 12 weeks of intoxication and their brains were collected for further examination, which encompassed measurement of the concentration of TBA-reactive products and free SH-groups. The revealed changes of TBA-reactive products and free SH-group concentration were not statistically significant.

[A fatal accident due to harvester wheel explosion--a case report].

A fatal accident of a 48 year old woman due to harvester wheel explosion has been presented in this paper. A faulty technical condition of the wheel and the fact that it had been pumped to a pressure exceeding the permissible limit was the reason for the explosion. The woman sustained multiorgan injuries and microscopic examination revealed inter-alveolar septa rupture and intra-alveolar haemorrhage and oedema. The microscopic changes of the lungs prove that the shock wave was released during the wheel explosion.

[Oxidative stress parameter analysis in rat brains during long-term ethanol intoxication].

The aim of this research was to define the influence of long-term ethanol intoxication on the changes in end products of lipid peroxidation, reacting with thiobarbituric acid (TBA-reactive products) and free SH-groups concentrations in rat brains. The experiment was conducted on male Lewis rats. The experimental groups received a 1-molar ethanol solution and the control group received tap water. The animals were killed after 4, 8 and 12 weeks of intoxication and their brains were collected for further examination, encompassing measurement of the concentration of TBA-reactive products and free SH-groups. A statistically significant increase in the concentration of TBA-reactive products in 4th week of intoxication and decrease in the concentration of free SH-groups in 8th and 12th week of intoxication--compared to the control group--was noticed.

[Frequency quotient of paternity index Qf in a case of replacement of the natural father within a trio with his brother].

Cases of trios in which the natural father's near blood-relative instead of the natural father are among the hardest to give an expert opinion on. The goal of this study was to determine with what frequencies specific given values of paternity index appear in trios with the natural father and with the natural father's brother, and whether these frequencies can be the basis for discovering the substitution of the natural father by a brother in a given trio examined. The study material was the population of genotypes investigated in the AmpF/STR SGM Plus system. It was seen that the higher the paternity index values, the more frequently they appear in trios with the natural father, and less frequently in trios with the natural father's brother. This dependency has a general character and obtained in all the systems studied. The frequency quotients Qf (defined as the frequency of a given PI value in trios with the natural father in relation to the "reduced" frequency of the PI value in trios with the brother of the natural father) are found in the region of c. 0.6 to c. 1.4, whereby extreme values are rare, and the most frequent are cases where Qf oscillates within modest limits around the value 1. This fact shows that the majority of cases, calculated Qf values contribute little to resolving the question of whether the defendant--or his brother--is the child's father.

[Practical usefulness of the IDENTIFILER system for paternity testing in the Central Poland population].

The usefulness of the IDENTIFILER multiplex system for paternity testing in the Central Poland population was examined. One hundred excluding cases and one hundred including cases were analysed and the results were estimated for two different types of cases: trios (standard cases) and duos (motherless cases). Efficiency of exclusion and paternity index were analysed for each locus as well as for the entire set of the fifteen STR markers.
