[Determination of the death time in children (1-3 years old) by the muscle contraction swelling (idiomuscular tumor)].

Was to research the muscles response in children during three years of their life to mechanical stimulation with evaluation of the maximum time of its occurrence from 2 to 15 hours of the postmortem period. Assessment of the muscles response to mechanical stress is one of the methods for determining the time of death coming. For the deceased of mature age, there is very little scientific data on this topic and for children and adolescents there is none at all.

Mast Cells in Renal Cancer: Clinical Morphological Correlations and Prognosis.

Morphofunctional activity of mast cells in renal cancer is studied on specimens from the center of the tumor, peritumorous zone (with an obligatory fragment of the pseudocapsule), and from renal tissues maximally distant from the tumor. The counts and areas of tumor cells were maximum in the peritumorous zone in comparison with intact kidney tissue and central zone of the tumor. Analysis of correlations revealed a direct correlation between the tumor cell count in the peritumorous zone and some clinical morphological parameters of the tumor (anaplasia degree, size, presence of invasion and metastases, and angiogenesis).

[Age changes of the connective tissue structures of human penis].

This investigation was aimed at the study of age changes of penis connective tissue structures. Tissue fragments of penis were obtained from 20 cadavers of men at the age of 20-38 years in group I, and from 20 cadavers of men at the age of 41-59 years in group II. The criteria for the exclusion of material from the research were arterial hypertension, diabetes mellitus, atherosclerosis of internal iliac arteries, Peyronie's disease, and anomalies of genital organ development.

[Modified method for the demonstration of argyrophilic proteins in the nucleolar organizer regions in paraffin sections].

The modified method of staining of argyrophilic nucleolar organizer regions (AgNORs) by silver nitrate is presented. This modification eliminates some disadvantages of an original technique. The method accelerates staining and prevents the precipitation of deposits.
