The aim of the present work was to assess the efficiency of thermal treatment of rape seeds in the reduction of its fat lypolysis in rumen and unsaturated fatty acids biohydrogenation. The studies were conducted using in sacco method with polyamide sacs on 6 rams of Merino breed with simple fistula of rumen. The protection of caked rape seeds involved its thermal processing at temperature 120^oC for 30 minutes. Raw and thermally processed rape seeds were incubated in rumen for 2, 4, 8, 16 and 24 hours and thermal decomposition of air dry mass, raw fat, fatty acids with various degree of saturation and particular fatty acids were studied. On the basis of the obtained results, it was found that thermal processing of rape seeds resulted in significant reduction of occurring in rumen lypolysis of their fat and biohydrogenation of unsaturated fatty acids (mono- as well as polyunsaturated). Moreover, it was found that in the seeds that were processed with thermal method, monounsaturated fatty acids were protected better than polyunsaturated ones.

The cervicothoracic or stellate ganglion belongs to the cervical part of sympathetic system. In animals it is formed by the combination of the caudal cervical ganglion with the first and often second thoracic ganglion. The study was conducted on 20 newborn Persian cats [7 males and 13 females] coming from the 58th day of gestation. The research has shown that the cervicothoracic ganglion is formed from the fusion of three or four ganglia: the caudal cervical ganglion [GCca], first thoracic ganglion [GTh1], second thoracic ganglion [GTh2], third thoracic ganglion [GTh3]. It is situated in C7-8 -Th1-3 segment. It is characterized by variable location relative to the cervical and thoracic segment of the vertebral column [skeletotopy] and various shape [oval, oblong, triangular, oblong with a distinct narrowing]. The morphometry of the examined cervicothoracic ganglion proved that the longest cervicothoracic ganglion is found on the left side in females [= 3.016 mm], the shortest on the right side also in females [= 2.790 mm]. The widest ganglion is found in males on the right side [= 1.758 mm], the narrowest in females on the left side [= 1.418 mm].

S. tundra is an parasite of roe deer (Capreolus capreolus), reindeer (Rangifer tarandus) and moose (Alces alces). This parasite belong to genus Setaria, which includes more then 40 species, that are localised in the abdominal cavities of ruminants and equines. All these species produce microfilarias, which are present in host blood circulation. Our case report is the invasion of Setaria tundra in roe deer (Capreolus capreolus) in Lower Silesia. The 4 years old female of roe deer was found death, in forest in February 2010. There were found 12 females and 2 males in abdominal cavity. The histological examination of a tissue slabs from lung showed presence of microfilaria in the lumen of vessels as well as blood smears.
