    Notes: Abstract A high percentage of endometrial carcinomas contain oestrogen and progesterone receptors. For endocrine therapy of recurrent endometrial carcinoma, only high-dose progestins are in clinical use. As, therefore, the development of new endocrine treatment strategies is of great interest, suitable animal models for this tumour are essential. Up to now, only human tumour xenografts transplanted in immune-deficient nude mice, but no syngeneic in vivo tumour models, have been available. In the present article we describe the hormone sensitivity of the EnDA endometrial adenocarcinoma of the DA/Han rat growing as s.c. implants in DA/Han rats and athymic nude mice in serial passage. In both species, the tumour expresses oestrogen, but no progesterone receptors. Transplanted in DA/Han rats or nude mice, ovariectomy reduced tumour weight by 64% and 46% respectively. In both species substitution of ovariectomized animals with oestradiol restored tumour weights to intact control levels. Oestradiol substitution of intact animals did not further enhance tumour growth. The growth of the primary tumour was inhibited by medroxyprogesterone acetate (MPA) at a dose of 100 mg/kg by 67% and by tamoxifen at a dose of 20 mg/kg by 38%. Lung metastases were regularly seen in both species, although to a lesser extent in nude mice than in DA/Han rats. Tamoxifen treatment did not alter the number of lung metastases, whereas MPA or ovariectomy produced a significant reduction in the number of lung metastases. The EnDA endometrial carcinoma of the DA/Han rat with respect to its oestrogen sensitivity, oestrogen receptor expression, morphology and metastatic growth, grossly resembles a typical endometrial adenocarcinoma and can therefore be regarded as auseful in vivo experimental model for the evaluation of new endocrine treatment strategies.

    Notes: Summary We report here that similar to E6-chicken retinal cells, dissociated cells from 5.5-day-old (E5.5) quail retinae reaggregate in rotary culture, multiply about tenfold and reestablish histotypical areas. These cellular aggregates include all nuclear layers either with inversed or correct laminar polarity, depending on the local origin of the cells (called “rosetted” and “laminar” in-vitro-retinae (IVR), respectively; Layer and Willbold 1989). In combined cultures, chick and quail cells are evenly mixed only during the first two days of culture. Along with the assembly of single cells into rosettes and then into discrete laminae, sectors of chick and quail cells begin to segregate. They are delineated by borders running radially through all three nuclear layers. Thus, interspecies migration of cells at this advanced stage of differentiation is strongly inhibited. Concomitant with this segregation, coherent radial columns spanning all three layers but containing cells from either species only, can be traced histologically. We conclude that a weak segregation of chick and quail retinal cells takes place already at the single cell level, but that the permanent segregation of entire tissue parts must be due to clonal cellular proliferation within the IVR in conjunction with some developmental-structural mechanism retaining clonal progenies within a columnar order.

    Notes: Summary Dissociated single cells from chicken retina or tectum kept in rotation-mediated cell culture aggregate, proliferate and establish a certain degree of histotypical cellto-cell relationships (“sorting out”), but these systems never form highly laminated aggregates (“nonstratified” R- and T-aggregates). In contrast, a mixture of retinal plus pigment epithelial cells forms highly “stratified” aggregates (“RPE-aggregates”, see Vollmer et al. 1984). The present comparative study of “stratified” and “nonstratified” aggregates enables us to investigate the process of cell proliferation uncoupled from that of tissue stratification. Here we try to relate these two basic neurogenetic processes with patterns of expression of cholinesterases (AChE, BChE) during formation of both types of aggregates. During early aggregate formation, in both “stratified” and “nonstratified” aggregates an increased butyrylcholinesterase activity is observed close to mitotically active cells. Quantitatively both phenomena show their maxima after 2–3 days in culture. In contrast, AChE-expression in all systems increases with incubation time. In nonproliferative areas, in the center of RPE-aggregates, the formation of plexiform layers is characterized initially by weak BChE and then strong AChE-activity. These areas correspond with the inner (IPL) and outer (OPL) plexiform layers of the retina in vivo. Although by sucrose gradient centrifugation we find that the 6S- and the fiber-associated 11S-molecules of AChE are present in all types of aggregates, during the culture period the ratio of 11S/6S-forms increases only in RPE-aggregates, which again indicates the advanced degree of differentiation within these aggregates. It is thus demonstrated that cholinesterases first correlate with neuronal cell proliferation and later with stratification, which indicates functions of both enzymes during both developmental periods.

    Description / Table of Contents: N-Thiocyanato and N-Cyano Derivatives of S, S-DimethylsulfodiimineN-Thiocyanato compounds 1 and 2 of S, S-dimethylsulfodiimine are formed by reaction of the corresponding N-bromo compounds with KSCN. The N-cyano compounds (3 and 4) are generated by condensation of S, S-dimethylsulfodiimine with cyanogenchloride. According to the reaction conditions N, N′ -dicyanosulfodiimine (4) hydrolyzes in two ways to give N, N′ -dicarbamoyl-S, S-dimethylsulfodiimine (5) and dimethylsulfone or 3-imino-5-oxo-1,1-dimethy1-4,5-dihydro-3 H-1,2,4,6-thia(VI)triazine (6). The properties of the new compounds are reported.
