Rates of DNA and RNA synthesis as well as transport of RNA into cytoplasmic structures of rat liver cells were studied after administration of amniocen preparation. The drug did not affect the rate of DNA and RNA synthesis in intact rat liver cells, while specific radioactivity of DNA was decreased in regenerating liver tissue 24 hrs after hepatectomy. Amniocen inhibited the rate of rRNA, mRNA and tRNA transport into cytoplasm but contributed to elevated penetration of nucleic acid precursors into rat liver cells. Effect of the drug on cell membrane system appears to be responsible for its biological action related to realization of genetic information.

This study is aimed at investigating the role of key molecular elements involved in pyroptosis in liver injury caused by exertional heat stroke (EHS). We established a model of EHS-induced liver injury in Sprague-Dawley rats, with a control group (receiving no treatment) for comparison and 12 rats in each group. Alanine transaminase (ALT) and aspartate transaminase (AST) levels in the blood were detected.

The aim of this study was to determine the antidotal potential of the chlorinated oxime K870 compared to obidoxime, as a monotherapy and in combination with atropine, in paraoxon (POX)-poisoned rats. The treatment doses of oximes were chosen as 20% of their LD values. The protective ratio (PR) of oxime K870 with atropine was significantly higher than that of obidoxime with atropine (68.

This study reports the development of a highly absorbent Chitosan (CS)/Tannic Acid (TA) sponge, synthesized via chemical cross-linking with Epichlorohydrin (ECH) and integrated with zinc oxide nanoparticles (ZnO NPs) as a novel hemostatic anti-infection agent. The chemical properties of the sponges were characterized using Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and zeta potential measurements. Morphological and elemental analyses conducted through scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDAX) revealed a uniform distribution of ZnO NPs, with particle sizes below 20 nm.

Acetamide is a hepatocarcinogen in rats. We previously revealed that acetamide induces characteristic large micronuclei in rat liver, suggesting the possible involvement of chromosome aberrations in acetamide-induced hepatocarcinogenesis. To elucidate the mechanism of large micronuclei formation, in this study we examined time-dependent changes in rat hepatocytes after administration of acetamide.
