[Detection of AB0 antigens in the bone tissue. The Thomsen phenomenon].

The proposed method allows for the most rational identification of bone tissue group specificity based on the results of quantitative absorption reaction and absorption-elution reaction. Original investigations of the author have demonstrated direct dependence of the identification on the detection of AB0 antigens in the tissues and their inactivation by neuraminidase enzyme.

[Single-stage detection of A and B antigens in the hair by absorption-elution and mixed agglutination techniques].

The proposed method is intended for single-stage detection of A and B antigens in ultrafine hair fragments by means of absorption-elution and mixed agglutination techniques with the use of a mixture of anti-A and anti-B sera.

[Differentiation of spermatic antigens and vaginal discharge in mixed spots].

The technique of differentiation of ABO antigens in a mixed spot of sperm and vaginal discharge based on higher electrophoretic mobility of spermatic protein compared to that of vaginal secretion is proposed.

[Blood grouping in mixed blood stains and excretions].

Blood grouping in mixed blood stains and excretions can often be a problem. It is related with the fact that, when blood and excretions of persons having different groups get mixed, the determinants of blood antigens of one person interact with the active centers of excretions' antibodies of another one and vice versa. The authors suggest a method to do away with the phenomenon.

[Efficacy of using different modifications of absorption-elution reaction for the detection of antigen P1 in blood stains].

Analyzed in the paper is the absorption-elution reaction (AER) of different modifications that is applied in forensic medical practice for detecting the P1 antigen in bloodstains. The treatment of blood stains by a 10% albumin solution (AER according to L. O.

[Effects of biological factors on isoantigens of ABO system].

The paper provides data about alterations of antigen ABO system in pathological states. These changes result from emergence and following action of the enzyme neuromidase to form latent determinant T.

[A method for group identification of hair infected with Microsporum].

A method for identifying the group appurtenance of biological objects from subjects suffering from various diseases is developed. The method can be used in examination of putrefactive objects (blood, secretions, hair, etc.) and in cases when the group appurtenance cannot be identified by other methods.

[The determination of haptoglobin in specimens of biological origin].

Presents the genetic aspects of haptoglobin in health, the rare types, and shifts of Hp fractions resultant from changes in the redox function (particularly in children) caused by high temperature, carbon monoxide, oxygen insufficiency, etc.

[The hair of an unknown higher primate? (1)].

The authors present the results of morphological, histochemical, and serological analyses of hairs found in the Caucasus and Tyan Shan. Two groups of signs were distinguished: (1) those characteristic of animals, i.e.
