A new Epstein-Barr virus nuclear antigen (EBNA) negative cell line SKW 4 has been established in vitro from a patient with diffuse histiocytic lymphoma. The SKW 4 seems to be an authentic human tumour cell line as evidenced by its EBV negativity, monoclonality and aneuploidy tested during early in vitro passage. The cell line expresses surface mu and kappa-chains, HLA-DR antigen, C3 and Fc receptors and B-cell lineage antigens. The karyotypic analyses demonstrated many numerical and structural aberrations. No Burkitt lymphoma associated translocations (t8;14, t2;8, t;22) were detected, but most of the markers found are those commonly associated with various types of human cancer. The SKW 4 thus represents the most common type of 'histiocytic lymphoma', that with a B-lymphoid cell phenotype, but is unique among HL derived lymphoma lines in its strong expression of a Helix pomatia A agglutinin binding surface glycoprotein of an apparent molecular weight of 75 000 daltons. 相似文献

Knife cuts in the coronal plane through various aspects of the midbrain tegmentum produced hyperphagia, hyperdipsia, or no effect on ingestive behavior. All of the cuts significantly depleted NE and 5-HT from hypothalamus and forebrain. The brains of hyperphagic or hyperdipsic animals did not differ from those of normophagic and normodipsic animals with respect to hypothalamic NE or 5-HT or telencephalic NE. Both hyperphagic and hyperdipsic animals had significantly lower concentrations of 5-HT in forebrain than rats which sustained similar cuts in the tegmentum which did not affect ingestive behavior. 相似文献

One group of male rats was reared continuously in small, stable colonies of three animals each during a ten-week period beginning when they were 46 days old. A second group of animals was also reared in small groups of three animals each but membership within these colonies was randomly changed at weekly intervals. Thereafter, all subjects were housed in individual cages. A 24 hr test of the subjects' aggression toward an unfamiliar male conspecific at 130-133 days of age indicated that only the heaviest animal in each of the stable colonies was aggressive. In contrast, all animals in the random-composition group were aggressive toward intruders. Scores on a second test of intruder-directed aggression administered when the subjects were nine months old were significantly related to scores on the first aggression test. Subtle variations in social experience during development are critical in establishing long-term patterns of aggression toward conspecifics in laboratory rats. 相似文献
