[Dynamics of the nuclear DNA content in the liver, skeletal muscles and myocardium of the rat in the postmortem period (a microspectrophotometric study)].

A comparative microspectrophotometric analysis of changes in nuclear DNA in the liver, skeletal muscle and myocardium of noninbred male albino rats which had died of cerebrocranial injury was conducted during three days following death. A decrease in the content of nuclear DNA within an interval of 30-72 h can be depicted mathematically by regression curves of the type M(t) = e-at+b. The data obtained allowed one to mathematically show the postmortem changes in DNA of the test material.

[Cystoscopy and endovesical biopsy in renal tuberculosis].

Cystoscopy and endovesical biopsy of the bladder wall were performed at early stages of investigation prior to the onset of tuberculostatic treatment in 77 patients with destructive renal tuberculosis, verified both bacteriologically and histologically. Cystoscopy proved to be valuable in 83.2% of the cases, particularly so where the destruction focus communicated with the renal calyx-pelvis system. Cystoscopic symptoms of renal tuberculosis occurred at the following rates: tubercles in 6.5%, focal hyperemia, in 18.2%, erosion and ulcer, in 9.1%, bullous edema of the ureteral opening, in 11.6%, all kinds of changes of ureteral opening, in 37.6%. There were no visible changes of vesical mucosa in 16.8%. The pattern of mucosal changes correlated with the markedness of X-ray morphological changes in the kidney. Endovesical biopsy was positive in 52%, its results, being significant in cases of open destructive developments and ureteral affection. The value of endovesical biopsy increased where it was performed at the peak of clinical and cystoscopic symptoms, at early stages of disease, before the onset of tuberculostatic treatment. False-negative results of endovesical biopsy do not exclude renal tuberculosis. High value of cystoscopy and endovesical biopsy makes them up-to-date diagnostic tests for renal tuberculosis.

[The mechanisms and characteristics of blood plasma potassium kinetics in the early postmortem period].

Studies of cadaveric and donor blood samples revealed a relationship between the temperature, extra- and intracellular volumes of water, red cell membrane status, time course of ionic composition of the blood, and thermodynamic effects emerging during cooling of tissues. This points to obligatory consideration for nosologic entity, specific features of patho- and thanatogenesis when assessing the time of death.
