Dynamics of amino acid composition of the medium in isolated organ culture by the controlled perfusion method / V. A. Barashkov [et al.] // Bulletin of Experimental Biology and Medicine. - 1975. - Vol. 80, Is. 7. - P759-761 . - ISSN 0007-4888

Аннотация: The dynamics of the amino acid composition of the perfusion fluid was investigated during adequate perfusion of isolated dog organs (the thorax and a complex consisting of the thoracic organs, kidneys, and liver). The concentration of amino acids such as histidine, lysine, and alanine in the perfusion fluid 6 h after the beginning of perfusion of the organ complex was higher, whereas that of arginine, serine, aspartic acid, threonine with glutamine, isoleucine, proline, leucine, and valine was much lower than initially. In experiments on the isolated thorax the dynamics of the amino acid composition of the medium was studied during perfusion for 4 h. The concentration of alanine, lysine, and histidine in the medium increased, whereas those of serine, aspartic acid, isoleucine, tyrosine, and phenylalanine decreased.

Аннотация: The dynamics of the amino acid composition of the medium was investigated during perfusion of the dog liver and kidney for 6 h with a mixture of autogenous plasma and medium No.199 in the ratio of 2:3. During culture of the kidney for 6 h the histidine concentration in the medium increased by 2.2 times compared with initially, the concentration of glutamic acid by 1.7 times, and of alanine and lysine by 1.6 times, whereas the concentrations of arginine, serine, and aspartic acid fell by 3.3 times and those of glutamine with threonine by 2.5 times. During perfusion of the liver the concentration of glutamic acid rose by 2.9 times, of alanine by 2.3 times, cystine by 2.0 times, and glycine by 1.5 times. The concentration of tyrosine fell by half, and that of phenylalanine and serine by 1.4 times. The arginine concentration fell so quickly during perfusion of the liver that by the second hour after the beginning of perfusion no arginine could be found in the medium. The method of amino acid analysis during organ culture as described can be used as a method of developing and correcting culture media.

HEPATOCYTES IN HETEROKARYONS DO NOT RETARD THE ENTRY OF STIMULATED FIBROBLAST NUCLEI INTO THE S-PERIOD [Текст] / N. A. SETKOV, V. N. KAZAKOV, T. V. ANDREYEVA // TSITOLOGIYA. - 1991. - Vol. 33, Is. 6. - P. 76-85. - Cited References: 39 . - ISSN 0041-3771

Аннотация: Serum-deprived (0.2 %) resting and serum-stimulated (10 %) proliferating NIH 3T3 mouse fibroblasts were fused with hepatocytes from intact, regenerating and embryonic mouse livers to elucidate mechanisms of liver cell proliferation, DNA synthesis being investigated in nuclei of heterokaryons and non-fused cells using radioautography. Hepatocytes in heterokaryons were found to have no inhibitory effect on the entry of stimulated fibroblast nuclei into the S-period, but on the contrary they were involved in DNA synthesis. In addition, the nuclei in heterokaryons mutually stimulated each other to enter the S-period. In their turn, the resting fibroblasts did not prevent the proliferating hepatocytes from the regenerating and embryonic livers to enter the S-period. Possible reasons of the absence of inhibitory effect of differentiated cells in heterokaryons are discussed. The data obtained enable us to conclude that the mechanism of proliferative process control in resting immortalized cells differs from that in differentiated cells where proliferation seems to be stopped without affecting the endogenous inhibitor postulated for the resting and ageing fibroblasts.

Аннотация: Hepatocyte proliferation in the liver regenerating after partial hepatectomy ceases when the organ is restored, and the mechanism of this phenomenon is still unclear. In the experiments on fusing hepatocytes from the reoenerated mouse liver (15 days after partial hepatectomy) with NIH 3T3 mouse fibroblasts, we revealed no DNA synthesis in the nuclei of stimulated fibroblasts in heterokaryons (in the presence of hepatocyte nuclei), whereas DNA synthesis in nonfused cells was undisturbed. In this work, our purpose was to find out whether the suppression of DNA synthesis in heterokaryons could be due to the appearance in hepatocytes of some endogenous factors having an inhibitory effect on proliferation. To this end, hepatocytes from the mouse liver regenerated after partial hepatectomy were treated with cycloheximide for 1-4 h and were then fused with stimulated fibroblasts. Such a short-term treatment of hepatocytes with cycloheximide proved to result in the loss of their ability to inhibit DNA synthesis in the nuclei of stimulated or quiescent fibroblasts in heterokaryons, but hepatocytes proper actively proliferated in the medium with a low serum content (0.2%). When the mice with the liver reoenerated after partial hepatectomy were treated with a single sublethal dose of cycloheximide (3 mg/kg), their hepatocytes taken two days after this treatment had no inhibitory effect. Puromycin, another inhibitor of protein synthesis, had the same effect on hepatocytes. These results may be interpreted as evidence that the final stage of liver regeneration after damage is controlled by the factors having a C C negative effect on cell proliferation.

Аннотация: Treatment of patients with mechanical jaundice (MJ) has been one of the topical problems of current medicine. The fraction of patients having MJ of oncologic character that can undergo radical surgery does not exceed 25-30%. A way out of such situation is to use minimally invasive endobiliary interventions, the main type of which is endoprosthesis replacement of bile duct lumens. The aim of the work was to study the biological properties of the experimental models of polymer stents made of PHA for endobiliary prosthetics and to investigate the biological properties of PHA suture material for forming of biliary-enteric anastomoses (cholecystoduodenostomy). Experiments were performed on 20 adult mongrel dogs, weighing 10-12 kg. The animals were divided to three groups: the negative control group (intact animals); the positive control group (the animals with implanted endobiliary silicon stents); and the experimental group (the animals with the PHA stents). The animals were monitored for 100 days. The clinical blood analysis was made before the operation, on day 7, 30, 60 and 100 days. During autopsy the presence of exudate, commissural process in the free abdominal cavity and subhepatic spatium, the appearance of choledoch where the prosthesis was located, as well as the appearance of cholecystoenterostomy, liver and duodenum. We did not found any signs of inflammation, cicatrical changes were estimated in the free abdominal cavity and subhepatic spatium. All implanted PHA stents were at their initial places of implantation. After the end of the experiment inflammatory reaction and anastomositis were absent. Macroscopic changes of liver and duodenum were also not detected. Liver function did not have any pathological deviations. These positive results give grounds to conclude that application of PHA as endobiliary stents in reconstructive surgery of bile passages and as suture material is a promising technology.
