The establishment of the presence of feces in stains by agar gel electrophoresis]

An electrophoretic method of feces determination in stains was developed. Method is based on detection of acid phosphatase only in feces since it is not detectable in human blood and other secretions by this method.     

The establishment of the presence and group classification of sperm in mixed stains by isoelectric focusing

The article deals with experimental data on design of the method used for detection of sperm, blood and vaginal secretions according to isoelectric points of acid phosphatases, differential diagnosis of ABO group antigens in "mixed" stains as well as detection of phenotype of red cell acid phosphatase by isoelectric focusing method.     

The simultaneous identification of seminal acid phosphatase and phosphoglucomutase by starch gel electrophoresis

Although elevated acid phosphatase (AP) activity in vaginal fluid is a consistent indicator for semen, differentiation between vaginal AP and seminal AP provides a more meaningful result. Detection of seminal AP in mixtures of vaginal AP, feces, and blood is accomplished by starch gel electrophoresis, employing the substrate thymolphthalein monophosphate as a selective visualization agent. Genetic phosphoglucomutase isoenzymes are simultaneously separated by this method and allow differentiation in some semen/vaginal fluid mixtures.     

The establishment of the presence of sperm in stains by an agar gel electrophoretic method]

Comparative investigation of seminal stains and other secretions from human body and blood as well as objects of plant origin by gel electrophoresis using alkaline values of pH buffer solutions and subsequent enzymography for acid phosphatase made it possible to develop optimal conditions for detection of seminal presence in stains. Good preservation of seminal acid phosphatase in stains during several years is shown.     

Determination of MN blood group from blood stains by electrophoresis and immunoblotting

The determination of blood groups from blood stains is extremely important in medicolegal practice, but there is the possibility of an error in the determination of MN phenotypes by the absorption-elution test. We investigated a new method applying electrophoresis and immunoblotting. As a consequence of various experiments, the most appropriate pretreatment of blood stains was as follows. Blood stains were immersed in physiological saline for 0.5 to 1 h and centrifuged. The supernatant was discarded. The sediment was dissolved in sample buffer (TRIS-buffered physiological saline containing 2% sodium dodecyl sulfate) and followed by thermodegradation. It was subjected to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). After transfer to a nitrocellulose membrane by Western blotting, MN phenotypes could be determined accurately from blood stains by an enzyme immunoassay (EIA) using commercially available polyclonal anti-M and anti-N sera. For blood stains more than 1 month old it was not easy to determine the MN phenotypes.

Evaluation of a nonequilibrium isoelectric focusing (IEF) method for the simultaneous typing of esterase D (EsD), red cell acid phosphatase (AcP1), phosphoglucomutase (PGM1), adenylate kinase (AK), and adenosine deaminase (ADA)

A nonequilibrium isoelectric focusing method incorporating the chemical spacers MOPS and HEPES was developed and subsequently evaluated for its ability to reliably discriminate common and rare phenotypes in the esterase D (EsD), red cell acid phosphatase (AcP1), phosphoglucomutase (PGM1), adenylate kinase (AK), and adenosine deaminase (ADA) isoenzyme systems. The validation procedures used were blind testing, comparison of results to conventional methods, and evaluation of known rare variant phenotypes. This method proved to be a quick and reliable method for typing all five isoenzyme systems, while providing an excellent probability of discrimination (PD = 0.96).     

The advantages of establishing the species classification of blood and other biological objects by the IFR in a quantitative modification

A quantitative modification of immunofluorescent test (IFT) is described. It was used for species identification of blood stains on material evidence objects. This modification is 1000 times more sensitive than electrophoretic methods traditionally used for this purpose in forensic medicine. Computer processing of the results helps objectively and persuasively determine the species appurtenance of blood and other biological objects. Results of the test represented as histograms should be attached to forensic medical conclusions as proofs for the court.     

Revision of requirements applicable to albumin (human), plasma protein fraction (human), and immune globulin (human). Food and Drug Administration, HHS. Final rule

The Food and Drug Administration (FDA) is amending the biologics regulations by removing, revising, or updating specific regulations applicable to blood derivative products to be more consistent with current practices and to remove unnecessary or outdated requirements. FDA is taking this action as part of the agency's "Blood Initiative" in which FDA is reviewing and revising, when appropriate, its regulations, policies, guidance, and procedures related to blood products, including blood derivatives.     

Determination of phosphoglucomutase (PGM1), acid phosphatase (ACP), and esterase D (ESD) in human bloodstains by hybrid isoelectric focusing (HIEF)

PGM1, ESD, and ACP were determined in bloodstain extracts by isoelectric focusing (IEF) with carrier ampholytes (CA) and HIEF. HIEF yields superior results in PGM typing from bloodstain extracts, whereas for ESD and ACP typing isoelectric focusing with carrier ampholytes seems to be the method of choice.

The establishment of the features of the blade of a stabbing-cutting weapon by the damages to human skin and to tricot clothing]

Presents forensic medical characteristics of the specific features of stabbed and cut injuries of human skin and jersey. Suggests a complex of signs that will help determine some structural parameters of a knife blade and the conditions of its interaction with the injured site of human body.     

Revision of requirements applicable to albumin (human), plasma protein fraction (human), and immune globulin (human). Food and Drug Administration, HHS. Direct final rule

The Food and Drug Administration (FDA) is amending the biologics regulations by removing, revising, or updating specific regulations applicable to blood derivative products to be more consistent with current practices and to remove unnecessary or outdated requirements. FDA is issuing these amendments directly as a final rule because the agency believes they are noncontroversial and that there is little likelihood that there will be comments opposing the rule. Elsewhere in this issue of the Federal Register, FDA is publishing a proposed rule under FDA's usual procedures for notice and comment in the event the agency receives any significant adverse comments. If any significant adverse comment is received sufficient to terminate the direct final rule within 30 days after the comment period ends, FDA will consider such comments on the proposed rule in developing the final rule. FDA is issuing this rule as part of the agency's "blood initiative" in which FDA is reviewing and revising, when appropriate, its regulations, policies, guidance, and procedures related to blood products, including plasma derivatives.     

The use of the obti test for determining the presence and type of blood in stains

A method for simultaneous detection and identification of the blood in stains on material evidence has been tried. Previously these two procedures were carried out in succession and took 2 days, while the new method takes 2-10 min. The method is highly sensitive and specific. Positive results were obtained only with human blood. The method is recommended for practice, specifically, for investigation of complex blood traces (washed and old) on material evidence.
