    A 7-year-old neutered female domestic short hair cat was presented with hind limb ataxia. A sub arachnoid cyst in the T10-T11 spinal cord region was identified by myelography as a collection of contrast medium in the subarachnoid space

    The trial was carried out over the period 1992–1993 at the "E. Pantanelli" experimental farm in Policoro (MT), in southern Italy. Eight cultivars, such as '044', '137', '271', '386-a', '386-lb', '386–2b', '307', '374', were seeded in polystyrene containers in June 1992 and transplanted into the field 37 days later with a density of nearly 12000 plants ha-1. The heads were harvests 19 times between November and May. The cultivars 044, '271', '307', 386-a', 386-1b' and '386–2b', produced the highest number of heads with an average of 209000 per hectare compared with cultivars 137 and '374' which produced 143000 heads ha -1. The mean yield time (MYT) was 147 days for the cv. 374 and 189 days for the cv. 044. Cv. 374 produced 20% of its total yield in 42 days, while cv. 044 did so in 179 days. All the cultivars produced 50% of their total yield in about 179 days except cv. 374 and '044' which took 187 and 191 days respectively. Total yield, number, weight and size of heads were lower in cv.374. The inflorescence complex ("pappus") was about 2 mm in the cultivars 044, '307', '374', and '386–2b', and 4 mm in '271' and '137'

    Cell proliferation and apoptosis in the pathogenesis of oesophagogastric lesions in pigs

    Recent studies have stressed the importance of epithelial hyperproliferation in the pathogenesis of early lesions (parakeratotic hyperkeratosis) of the porcine gastric pars oesophagea (PO). In this study, immunohistochemical staining with Ki67 (clone MIB 1) and AgNOR proteins silver staining were used to evaluate, by means of image analysis, cell proliferation in normal and parakeratotic (parakeratotic hyperkeratosis) epithelia of the PO. Apoptotic activity was also assessed with the TUNEL assay and compared with cell proliferative parameters. Early lesions of the PO were characterised by a significant increase in epithelial proliferative activity while there was no difference in the apoptotic activity between normal and parakeratotic epithelia. Our data confirm the hyperproliferative nature of epithelial changes preceding degeneration and erosion/ulcer of the PO and suggest that an underlying feature of gastric ulcers in pigs is an imbalance between cell proliferation and programmed cell death. © 2000 Harcourt Publishers Ltd
