Explorative Image Analysis of Methylene Blue Interactions with Gelatin in Polypropylene Nonwoven Fabric Membranes: A Potential Future Tool for the Characterization of the Diffusion Process.

This manuscript explores the interaction between methylene blue dye and gelatin within a membrane using spectroscopy and image analysis. Emphasis is placed on methylene blue's unique properties, specifically its ability to oscillate between two distinct resonance states, each with unique light absorption characteristics. Image analysis serves as a tool for examining dye diffusion and absorption.

[A RARE CLINICAL CASE OF CONGENITAL HYPOPROCONVERTINEMIA].

The paper reports a rare clinical case of congenital hypoproconvertinemia in an elderly woman repeatedly admitted to the Cardiological Department for the management of coronary heart disease and arterial hypertension. The detection of low prothrombin index in a series of analysis requiredfurther hematological examination that revealed the history of postoperative and postnatal hemorrhage along with markedly reduced factor VII level. These results were interpreted as evidence of a rare congenital pathology, hypoproconvertinemia.

Pathogenesis and pharmacorrection of early postresuscitation cardiac arrhythmia.

Effect of acute lethal blood loss on character and frequency of cardiac arrhythmias in postresuscitation period has been studied. Experiments were carried out on mongrel male rats resuscitated after 4- and 6-min clinical death caused by acute blood loss. Electric cardiac instability was found in early postresuscitation period.

[Peripheral blood and bone marrow cell status of white rats with long-term lead exposure].

Blood test and bone marrow examination in experiments with albino rats weighing 100-110 g subjected to long-term lead influence (1% lead acetate per os) showed availability of reticulocytosis with thrombocytopenia (on the 62d day) and thrombocytosis on the 92d day of the experiment) in peripheral blood. Reduction of the bone marrow neutrophil index and leuko-erythroblastic ration due to an increase of an erythroblastic radicle was recorded in the bone marrow.

[Ultrastructure of erythroid cells in chronic phenol poisoning].

Ultrastructure of the erythroblastic cells was studied under chronic phenol intoxication. Certain changes in the cells are revealed at early stages of their development: an increase in size of the Golgi complex bodies in the proerythroblasts, hyperosmotic mitochondria with vacuolization and breaking of cell membrane in the basophilic erythroblasts. The latter shows the reduction of oxidative phosphorylation.

[State of guinea pig peripheral blood and bone marrow cells in phenol poisoning].

Blood tests and examination of bone marrow in 2-3 week guinea pigs under conditions of a long-term phenol intoxication (0.5 mg/kg perorally) showed the presence of thrombocytopenia and eosinophilia in peripheral blood and a decrease of the erythroblast maturation index in bone marrow. In the experiment with animals treated with a high dose of phenol there was an evidence of thrombocytopenia accompanied by reticulocytosis and a nuclear shift of neutrophils to the right.
