A 10-week-old miniature dachshund presented with acute onset of weakness. Electrocardiography showed sustained ventricular tachycardia, and thoracic and abdominal radiography revealed pleural and peritoneal effusion. Echocardiography revealed severely hypokinetic left and right ventricles. Thoracocentesis and abdominocentesis and subsequent transfer to an oxygen chamber yielded no clinical improvement, and the dog died about 1 hr after admission. Gross examination of a longitudinal section through the entire heart revealed poorly demarcated focal or patchy areas of grayish-white tissue infiltrating extensively into the myocardium. Histologically, these lesions were consistent with infiltrative proliferation of neoplastic lymphoid cells. Immunohistochemical staining confirmed the diagnosis of primary cardiac lymphoma (PCL) of T-cell origin. There have been no previous reports of such young dogs with PCL.

Spasticity following cerebral vascular accidents (CVAs) is a common occurrence, but remains a problematic entity to treat and interferes with mobility and self-care activities which are critical for successful rehabilitative outcomes. Low reactive-level laser therapy (LLLT) has attracted attention in a number of areas including spasticity associated with cerebral palsy. In the case of post CVA therapy, LLLT has been reported for pain treatment, but not spasticity. The present study examined the efficacy of LLLT in attenuating triceps surae muscle spasticity in CVA patients. The study subjects comprised 15 chronic CVA patients with spasticity, treated at our university hospital between 2002 and 2006. The LLLT device we used was a near infrared (830 nm) semiconductor laser device delivering 1 W in continuous wave (irradiance, 670 mW/cm2) . The laser probe was applied with mild pressure to the skin over the tibial nerve on the affected side, 30 sec/point (dose/point 20.1 J/cm2) repeated 3 times with a 5 sec interval between irradiations. Two sessions were given per week for 1 week. At the end of the week, we recognized LLLT effects in 11 cases out of 15. The other 4 patients had little or no effect but were in their fifties, and had successive bouts of ankle clonus. LLLT is a promising medical treatment for the attenuation of CVA-related spasticity of the triceps surae muscle spasticity, and facilitate voluntary movements in such patients. Further studies are warranted to elucidate the mechanisms by which LLLT can attenuate spasticity.

A Ce3+ complex with tetradentate ligands based on benzimidazole moieties was synthesized. The photochemical properties of the Ce3+ complex were studied via absorption and emission spectra and emission quantum yield measurements. The effective values of the molar absorption coefficient and the emission quantum yield were estimated to be 890 dm3 mol−1 cm−1 and 0.58, respectively; these values are relatively large compared to those of common rare-earth metal complexes that exhibit 4f–4f emissions.
