Abstract
A straightforward access to pyrrolidine-based analogues of jaspine B was developed. Five stereoisomers were prepared including the all-cis derivatives presenting the configuration of the natural anhydrophytosphingosine. The synthesis of the latter relied on an original Staudinger-type cyclization process. The compounds were evaluated regarding their ability to alter tumor cells' viability and to interfere with the metabolism of sphingolipids.

Abstract
Three groups of Sprague-Dawley CD rats (males and females) were initially administered p.o. with ebrotidine, a novel H2-receptor antagonist, mixed with the diet, at 50, 200, and 500 mg/kg/d, respectively. Two concurrent control groups of animals were used. After 13 months, initial 200 mg/kg was lowered to 150 mg/kg, and a new group was administered with 300 mg/kg, due to the body weight reduction observed in the top dose group. After 24 months, survivors were killed and necropsied, and a histopathological study was performed. The frequencies of the different tumour types that were found were not raised due to the treatment. Lower frequencies of some types of pituitary and mammary gland tumours, in the groups treated with the higher doses, were the only statistically significant changes. Among the non-neoplastic effects, a lower body weight increment and food consumption (500 and 300 mg/kg, both sexes), lower survival (500 mg/kg, males), presence of lipoid pneumonia (500 mg/kg, only in males, and 300 mg/kg, both sexes), and lithiasis in urinary system (500 mg/kg) were observed. No changes in gastric mucosa (the main target organ) were attributable to ebrotidine. Regarding the non-neoplastic effects, 150 mg/kg was the no observed adverse effect level. According to the previous results of the carcinogenicity study in mice, conjointly with those of the study in rats reported here, there is no evidence of carcinogenic risk either in males or in females in these species.

Abstract
The results from two carcinogenicity studies on ebrotidine (N-[2-(E)-[[2-[[[2-[(diaminomethylene)amino]-4-thiazolyl] methyl]thio]ethyl]amino]methylene]-4-bromo-benzenesulfonamide, CAS 100981-43-9, FI-3542) conducted in mice and rats are reported. Oral doses of 50, 200 and 500 mg/kg were administered to mice for 18 months and 50, 200 (150), 300 and 500 mg/kg were administered to rats for 24 months. The study design was prepared according to EEC guidelines, and the recommendations by the International Agency for Research on Cancer were used for the statistical analysis of data. Weekly palpations were made along the course of studies and general parameters were monitored. The only effects attributed to ebrotidine administration were a slight decrease in the survival rate of female mice given the 500 mg/kg dose and a lower weight gain in rats of both sexes. The histopathological data revealed that lipoid pneumonia and kidney calculi are more frequent in rats treated with doses of 500 and 300 mg/kg. No increment in the spontaneous occurrence of tumours or significant presence of tumours in treated animals differing from that in control animals was observed, and a decrease in the time required for their onset that could be related to ebrotidine was not observed either. There were no differences in hyperplastic and/or dysplastic changes between treated and control animals. Therefore, it is deduced that ebrotidine does not induce neoplastic or preneoplastic effects in rats or mice even at doses of 500 mg/kg, at which some general toxicity effects are seen.

Abstract
The spread of Vesical Neoplasia occurs frequently through local or regional extension. Its systemic dissemination happens frequently in advanced phases but it is exceptional as initial manifestation. The case of an undifferentiated vesical carcinoma is described, its presentation was as a big size osteolytic lesion on the sacrum. Local manifestations of the tumor appeared later. The study performed both in bones as well as in the vesical mucosa showed an undifferentiated adenocarcinoma. The great resemblance and histological and immunohistochemical concordances of both biopsies confirmed that it was a primary vesical neoplasia with a metastasis in sacrum. The specific clinical evolution of this tumor is discussed which is probably related with the fact that it is an undifferentiated carcinoma.

Abstract
A 24-year-old man developed progressive dementia in seven years. The patient suffered a severe bronchopneumonia and eventually died few days later. Brain coronal sections showed a soft gray-brownish discoloration of white matter of centrum ovale but the subcortical arcuate fibers and the interne capsule were preserved. Microscopically, the white matter showed marked loss of myelin and oligodendrocytes, abundant hypertrophic astrocytes and numerous "globoid cells". The latter showed strong positivity in immunostains for a mouse monoclonal antigalactocerebroside antibody. The presence of these cells in the brain white matter might be the morphological basis to classify the present case as one of Krabbe's Leukodystrophy.

Abstract
Several authors have suggested that the risk of developing aminoglycoside nephrotoxicity is greater in cirrhotic patients than in the noncirrhotic population. However, this has not been confirmed by other investigators. To compare the intensity and characteristics of aminoglycoside nephrotoxicity in cirrhotic and normal rats, 31 rats with carbon tetrachloride-induced cirrhosis with ascites and 35 control rats were treated with gentamicin. Each group of rats was divided into two subgroups in order to receive 10 or 40 mg per kg per day of gentamicin, and different subsets of animals were killed on Days 4, 8 and 12 of treatment for renal histological examination and determination of renal tissue gentamicin concentration. Urine volume, osmolality, sodium excretion and N-acetyl-beta-D-glucosaminidase activity were measured daily throughout the study. Creatinine clearance and trough plasma concentration of gentamicin were determined in each animal immediately before killing. There were no significant differences between cirrhotic and control rats in relation to the magnitude of changes in urine volume, osmolality, sodium excretion and N-acetyl-beta-D-glucosaminidase activity and creatinine clearance during gentamicin administration. The values of a histopathological score semiquantitatively assessing the renal morphological changes observed by light microscopy were not significantly different in cirrhotic and control rats. In addition, similar trough plasma and renal cortical tissue concentrations of gentamicin were observed in both groups of animals. These results suggest that, in this experimental model, cirrhosis does not increase the risk for aminoglycoside nephrotoxicity.

Abstract
A two-generation reproduction-fertility study of cyanamide in the rat has been carried out. After oral administration of 2, 7 and 25 mg/kg/day of the drug, relevant changes have been noted at the highest dose level. Decrease in dam weight gain, in number of corpora lutea, in number of implantations and in number of neonates have been observed in rats of the Fo generation after treatment with 25 mg/kg/day. This group showed a reduced fertility rate and decreases in the weight of several reproductive organs male rats. In contrast to the findings noted in the Fo generation, changes related to cyanamide treatment have not been observed in the F1 generation. Histopathology of these organs has disclosed a low incidence of bilateral testicular atrophy. Decreased fertility rate due to non-specific toxicity associated with a diminished food intake cannot be discarded.

Abstract
Investigations were carried out in 122 patients in order to identify features of Sjögren's syndrome (keratoconjunctivitis sicca and xerostomia). There were 78 patients with autoimmune diseases (rheumatoid arthritis 21, scleroderma 16, sicca syndrome 16, primary biliary cirrhosis 14, and other autoimmune disorders 11), 11 patients with chronic liver disease other than primary biliary cirrhosis, and 33 patients with a variety of non-autoimmune conditions or no obvious disease. Keratoconjunctivitis sicca was diagnosed by Schirmer's test and rose bengal staining. The oral component was diagnosed by labial biopsy and salivary scintigraphy. Forty nine patients had a definite Sjögren's syndrome, and 77 patients had the syndrome definitely or probably. Definite Sjögren's syndrome occurred in 62% of patients with rheumatoid arthritis, in 69% of patients with scleroderma, and in 71% of patients with primary biliary cirrhosis. Sjögren's syndrome was not present in any of the patients with non-autoimmune conditions. These results show that in an unselected group of patients with Sjögren's syndrome the prevalence of rheumatoid arthritis (26%), scleroderma (22%), sicca syndrome (22%), and primary biliary cirrhosis (20%) is similar. Also the occurrence of Sjögren's syndrome in primary biliary cirrhosis is even higher than that in rheumatoid arthritis.
