Fatty acid composition of lipids of Escherichia coli W 1655 F+ and its stable protoplast type L-form
J. Gumpert W. Schade D. Krebs S. Baykousheva E. Ivanova As. Toshkov 《Journal of basic microbiology》1982,22(3):169-174
The comparative fatty acid analysis of extractable and non-extractable lipids of Escherichia coli W 1655 F+ and its stable protoplast type L-form shows quantitative as well as qualitative differences. From 10 different fatty acids obtained 16:0, 17:0, and 18:0 are present at about the same quantities in the lipid fractions of the bacterial and L-form. The absence of larger amounts of 12:0, 14:0, and 14:βOH fatty acids in non-extractable L-form lipids reflects the loss of the cell wall in L-form cells. 16:1 fatty acid was found in L-form lipids only. This qualitative difference and the 2–3 times higher content of 18:1 in L-form lipids and the 7 times lower content of cyc 19:0 in extractable lipids of the L-form may be interpreted as alterations characteristic for the changed composition of the cytoplasmic membrane in L-form cells. 相似文献

Tocopherol-enriched liver microsomes are more resistant to lipid peroxidation at an alkaline pH of 8.5 in comparison with
microsomes incubated at pH 7.5. An alkaline pH provides conditions for two-electron oxidation of tocopherol, which causes
the lipid molecule to revert to the initial state (O2/H exchange). A possible mechanism of inhibition of lipid peroxidation within the physiological range of pH with participation
of a glutathione-dependent enzyme is discussed.

The rate of cholesterol synthesis in peripheral blood lymphocytes and plasma lipid and lipoprotein spectra are studied in
patients with isolated hypercholesterolemia and combined hyperlipidemias (IIa and IIb hyperlipidemias according to Frederickson
classification).14C-acetate incorporation into cholesterol in peripheral blood lymphocytes is considerably higher in patients with type IIb
hyperlipidemia. Lipanthyl-200M reduces the rate of cholesterol synthesis in lymphocytes of both groups. A direct correlation
is established between serum triglyceride level and the rate of cholesterol synthesis.

Endoprostheses made from knitted fabric of 3 loop types were used for hernioplasty in rats. Biocompatibility of implanted
textile constructions was evaluated after 6 months. The intensity of inflammatory reaction and types of complications in animals
depended on the loop type and method of finishing of the mesh endoprosthesis tissue.

Histochemical characteristics of acid mucopolysaccharides (MPS) of the renal medulla were compared with the indices of kidney function in dogs during water and osmotic diuresis and polyuria induced by administration of heparin. Changes in staining for MPS were found to correspond to the intensity of reabsorption of osmotically free water. The results suggest that changes in the physicochemical properties of MPS are one of the significant factors determining the permeability of structures of the renal medulla to movement of water from the lumen of the tubules into the interstices. 相似文献
