CpG-oligodeoxynucleotide (CpG-ODN) is not only reported to protect against airway hyper responsiveness but is also known as a potent vaccine adjuvant for anti-tumor therapy. Little is known about the effect of CpG-ODN in mice with radiation-induced lung fibrosis (RILF), a common late stage form of tissue damage that occurs after thorax radiotherapy (RT). Here, we evaluated the immunomodulatory effects of CpG-ODN on the development of RILF. Mice were divided into four groups: (1) RT, single dose of 12Gy to the whole thorax; (2) CpG, only intraperitoneal injection of CpG-ODN for total 5 weeks; (3) RT+CpG, irradiation plus CpG-ODN treatment before and after irradiation for total 5 weeks; and (4) control (CTL): No RT or CpG-ODN treatment...

The biological effects of different wavelengths of light emitting diode (LED) light tend to vary from each other. Research into use of photobiomodulation for treatment of skin wounds and the underlying mechanisms has been largely lacking. We explored the histopathological basis of the therapeutic effect of photobiomodulation and the relation between duration of exposure and photobiomodulation effect of different wavelengths of LED in a Japanese big-ear white rabbit skin-wound model. Skin wound model was established in 16 rabbits (three wounds per rabbit: one served as control, the other two wounds were irradiated by red and blue LED lights, respectively)...

The clinical and pathomorphologic data demonstrate that the most frequent cause of cardiac infarction is the formation of "soft" atheromatosis plaques in the intima of arteries. Their rupture results in thrombosis of coronary arteries. The plaques are characterized by higher content of triglycerides. On the basis of the research data, it is possible to validly consider that the detection of secretary phospholipase content A2 conjugated with lipoproteins is the test of systemic inflammatory response. This response is formed under atherosclerosis in vivo as a feedback to the accumulation in the intercellular medium of the endogenic flogogens (initiators of biological reaction of inflammation)--lipoproteins of lower density subclass A...

The pathological changes observed in the organs in Macacus rhesus monkeys which have succumbed to severe infection with Bartonella bacilliformis are similar to those found in human organs in persons dying of Oroya fever. The characteristic changes in the liver are the zonal necrosis of the cells around the hepatic veins, involving active macrophagocytosis of invading polymorphonuclear leucocytes in the necrotic areas, and a marked endothelial hyperplasia in the sinusoids or around the portal veins. In some instances there is fatty infiltration of hepatic cells...

Sinusoidal alterations unrelated to primary hepatocellular damage present without characteristic clinical findings and in these cases the liver biopsy is particularly important. Capillarization of sinusoids is characterized by closing of fenestration, formation of a basal membrane and by the expression of CD34 and is typical for active cirrhosis. In nodular regeneratory hyperplasia, capillarization indicates a local or general disturbance of perfusion. In large regenerative nodules, focal nodular hyperplasia and liver cell adenoma CD34-positive capillaries reflect afferent parts and CD34-negative sinusoids the efferent parts of the parenchymal vascular bed...

A 69-year-old man was admitted to our hospital with fever and right neck lymphadenopathy. A neck lymph node biopsy was performed. In the specimens, immunoblasts were present with an admixture of small T lymphocytes and macrophagocytes. Immunohistochemcal staining of immunoblasts was positive for CD20, CD30 and EBER. Epstein-Barr virus (EBV) serology showed elevated IgG antibody to VCA, and EBV DNA was detected in the peripheral blood. Since he showed latency II without immunodeficiency disease, we diagnosed age-related EBV-associated B-cell lymphoproliferative disorder (EBV-LPD) as a result of aging and EBV infection...
