[Adipocyte size in primary hypertriglyceridemia with and without obesity (author's transl)].

Adipose tissue cellularity of patients with endogenous hypertriglyceridemia whether associated with obesity or not has been studied by means of a semiautomatic method of counting and sizing osmium tetroxide fixed adipocytes. Cell population distributions were analyzed by mathematical computation. The Coulter Counter system was able to determine mean diameter (or volume) and cell size dispersion which defined adipocyte population. An overall shift of cell population size has been found to characterize adipose tissue cellularity of the different groups examined. Adipocyte population in the obese was defined by increased fat cell size with overlapping distributions between both groups of same weight. Nevertheless normolipemic obese patients were characterized by larger cell size than hypertriglyceridemic subjects matched for adiposity index. The results are discussed in relation to the removal defect found in endogenous hypertriglyceridemia.

Adipose Tissue

[Disorders of hemostasis during intake of lipids].

Lipid emulsions based upon soya triglycerides and widely used in parenteral nutrition. Haematological surveillance of the patients, and in particular the study of coagulation, shows slight changes in platelet adhesiveness and a transient hypercoagulability state proportional to the concentration of the lipid emulsion. Nevertheless, these findings must be interpreted with the greatest caution, inasmuch as the laboratory tests involved are technically delicate. The results obtained may be contradictory according to the protocol used. Finally, in patients receiving intensive therapy, there are multiple factors (stress, prolonge;d bedrest, hypercatabolism) which may alter coagulation quite independently of the prescription of lipids.

[Studies of lipoprotein lipase activity and adipocyte characteristics in the human: effect of obesity and diabetes (author's transl)].

Adipose tissue lipoprotein lipase activity (LPLA) and cellularity have been studied in controls, in diabetic or non-diabetic obese subjects and in insulin dependent diabetic patients. LPLA is increased in diabetic or non-diabetic obese subjects and in insulin dependent diabetic patients. LPLA is increased in diabetic or non-diabetic obese subjects (p less than 0.02) and decreased in insulin dependent diabetic patients (p less than 0.02). Adipocyte size is larger in obese subjects, whether diabetic or not (p less than 0.05). As defined by LPLA and cell size means, the different groups are related linearly. The implications of this relationship between LPLA and adipocyte size are considered.
