Preliminary results of monitoring research on zearalenone presence in blood of women with neoplastic lesions in reproductive system

The aim of the monitoring of zearalenone presence in the blood plasma of women with neoplastic lesions in the reproductive tract was to asses whether the phytosteride is noted in the patients blood and whether the correlation exists between its presence and the incidence of particular neoplasm. The presence of zearalenone or its metabolite--alpha-zearalenole, was noted in 13.51% of the examined women. In 60% of the patients with the confirmed presence of the xenobiotic it was noted in the lowest concentrations. These patients had neoplastic lesions of Carcinoma corpus uteri type.     

Peliosis hepatis-like lesion in a pekingese dog. A case report

Peliosis hepatis (PH) is a rare condition characterized by dilatation of hepatic sinusoids and the presence of blood-filled spaces within the liver. The disease occurs mainly in subjects exposed to toxic substances or estrogens, and is often asymptomatic. A 9 year-old pekingese female dog was sent to Division of Pathology for autopsy because of sudden death of unclear cause. Autopsy revealed severe hydroperitoneum (1500 ml of transsudate), dilatation of heart ventricles, passive hyperemia of lungs, spleen and kidneys. The liver was enlarged, with slightly wrinkled surface, with many red spots, of different size and shape. Microscopic examination of the liver revealed the presence of areas with severe dilatation of hepatic sinusoids, and multiple cystic spaces filled with blood. Some of these spaces were lined with endothelium and other were not. Spaces were different in shape and size and were localized in the areas between dilated sinusoids. Based on the macroscopic and microscopic examination, the liver lesions were identified as severe hepatic sinusoidal dilatation with formation of peliosis hepatis-like structures.     

The effects of prenatal exposure to methylxanthines

This review discusses epidemiology and laboratory studies on the effects of prenatal methylxanthine administration on some systems developing organisms. They are mainly absorbed from coffee, tea and cocoa products such as cola beverages and chocolate bars. Prenatal methylxanthine exposure can induce several unfavourables changes in the developing organism, which are persistent even in later phases of life. Based on results obtained from animal studies, the effect on embryogenesis is not only poorly understood but also controversial. It is therefore important to study interspecies differences as results may differ depending on animals used and administration methods.     

Assessment of treatment of Osteochondrosis dissecans (OCD) of shoulder joint in dogs--the results of two years of experience

Osteochondrosis is a common and clinically important joint disorder that occurs in human and many species of animals such as pigs, horses and dogs. The aim of this article is to present the results of conservative and surgical treatment of Osteochondrosis dissecans (OCD) and to compare the recovery time in relation to race, age and extent of cartilage damage. The study was performed on 36 dogs of both sexes, aged from 4 to 24 months, weighing 12-70 kg, of different breeds (predisposed and non-specific for this disease). All patients underwent clinical, orthopedic and radiological examination through which the location of OCD changes in the shoulder joint and the degree of this problem were established. Based on the examinations the patients were qualified for particular treatment procedures. Control tests were performed after 14, 30 and 60 days, which allowed for a precise evaluation of the progress of therapy. Achieved results indicate that dogs age and the lesions extent in the shoulder joint have an impact on the outcome of treatment. Studies showed that the best therapeutic effects were obtained in dogs aged 6-10 months, which underwent surgery. The study proved that the early diagnosis of OCD strongly influence the recovery rate and may inhibit the development of degenerative changes in the joint (DJD).
