Recently, hyperbaric oxygen therapy with a lower pressure and oxygen concentration (L-HBOT) than previous methods has been used for dogs in Japan; however, the influences of L-HBOT on dogs have not been clarified. To verify the influences of L-HBOT on physiological mechanism in dogs, we investigated blood gas parameters, glutathione peroxidase (GPx) activity, heart rate variability, stress-related hormones and skin conductance (SC) in 4 clinically normal beagle dogs with catheters in their carotid arteries and jugular veins when they were quiet, after running, after receiving L-HBOT (30% oxygen concentration, 1.3 atmospheres absolute, 30 min) or after not receiving L-HBOT. The results showed there were no changes in blood gas parameters, heart rate variability and catecholamine levels after L-HBOT. GPx activity was significantly higher, and the SC and cortisol level were lower in dogs that received L-HBOT than those when they were quiet. These results suggested that L-HBOT may have a small influence on oxygenation dynamics, activate antioxidant enzymes such as GPx, restrain autonomic nervous activity and control the balance between oxidation and antioxidation inside the body.

A 4-year-2-month-old female Japanese domestic cat was diagnosed with lymphangiosarcoma through tissue biopsy of an amputated leg. Two months later, the cat was euthanized, and postmortem findings revealed edema, and bruising at the caudal region of the trunk, pulmonary hemorrhage, pulmonary nodules and mediastinal lymphadenopathy. Microscopically, neoplastic tissues were observed in the dermis and subcutis of the trunk, lung, mediastinal lymph nodes, diaphragm, omentum and mesentery. The tumor cells were spindle to polygonal-shaped with nuclear pleomorphism aligning along pre-existing collagen bundles and forming irregular vascular channels in which the erythrocytes were rarely observed. These cells were immunopositive for vimentin, von Willebrand factor and CD31. Based on the histopathological and immunohistochemical features, the neoplasia was diagnosed as lymphangiosarcoma with systemic metastases.

How can the research trends in Japanese family sociology of the past two decades be described from the perspectives of social research? The author tries to explore the trends, if any, by reviewing the related articles in Japanese Journal of Family Sociology and Annals of Family Studies, focusing on the data collecting methods and the objects of the analysis. This review shows that qualitative studies are on the wax and quantitative studies are, on the other hand, on the wane in number. In qualitative studies, articles using interview methods have increased remarkably. The main objects of the interview are women such as wife and mother, while new objects like care-workers and non-heterosexuals have recently emerged. In quantitative studies, articles using first hand data have decreased and those using secondary analysis have increased. The objects of the analysis are inclined to concentrate on the member of the nuclear family", especially wives and mothers. The author suggests that the research target should include men's experience in family life, so that the qualitative and quantitative studies can be more correlated, leading to leveling up the quality of the articles using quantitative approaches.
