The relationship between lipid serum levels and coronary atherosclerotic plaque fat content was studied in 51 necropsy patients. Serum lipids were measured by standard techniques, during life, in the absence of lipid-lowering drugs. Intima, intimal fat and media areas were measured using a computerized system in cryosections of the odd segments of the right, anterior descending and circumflex coronary arteries stained with Sudan-IV. Mean intimal and lipid areas were 5.74 ± 1.98 and 1.22 ± 0.55 mm² (22.12 ± 8.48%) in 26 cases with high cholesterol (³200 mg/dL) and 4.98 ± 1.94 and 1.16 ± 0.66 mm² (22.75 ± 9.06%) in 25 cases with normal cholesterol (<200 mg/dL; P > 0.05). Patients with high levels of low-density lipoprotein (³130 mg/dL, N = 15) had a... |

Individual determination of ploidy level in experimentally induced triploid bivalve molluscs using image cytometry. The sexual maturation in bivalve molluscs causes decreased growth and sometimes increased mortalities. These drawbacks can be avoided by genetic sterilization (triploidy). Triploïdy induction require a egg treatment and a ploidy control at each generation. The ploidy level is usually determined by counting the chromosomes, a technique which is relatively easy for the trochophora stage and for juveniles measuring from 5 mm to 3 cm only. ln order to be able to follow up the evolution of the ploidy rate during any stage of animallife, we have developed an estimation method based on image cytometry. Individual DNA content is determined by... |
