[The effect of a low-intensity helium-neon laser on succinate dehydrogenase activity in unmineralized periodontal and dental tissues].

Laser effects with energy density of 28.8, 86.4, 144 J/cm2 and 86.

[Proof of stimulating effect of dalargin of the process of cell division through opiate receptors].

The role of opiate receptors on cell division in corneal epithelium during administration of dalargin was analysed. Naloxone injection/200 micrograms/kg/decreased MI two times, DNA-synthesis 1.4 times over 24 hours.

[Effect of a stable analog of leu-enkephalin, dalargin, on the cell division of the corneal epithelium in white rats].

The effect of Leu-enkephalin analog--dalargin--on the corneal epithelium proliferation has been studied in white rats. 10 microliter dalargin per 1 kg body weight were administered intraperitoneally at 8 a.m.

[Effect of opioid receptor ligands on cell division processes in the corneal epithelium of the white rat].

The effects of the application of synthetic leu-enkephalin analogue--dalargin and naloxone on DNA synthesis and cell division in corneal epithelium were studied with the drugs injected once or five times. The influence of one and five intraperitoneal injections of the drugs in question at a dose of 10 micrograms/kg body weight was also investigated. In both cases the opioid receptor ligands examined activated DNA synthesis with the following adequate increase in mitotic index.
