A case of non-Hodgkin's lymphoma with macroglobulinemia is reported. A 48-year-old man consulted our hospital with complaints of dysphagia and sleep apnea. On the first examination, degree III hypertrophy of tonsils, Bence-Jones protein of K-type on urinalysis, and an M-peak in the gamma-glb. Beta-glb areas on fractionation of protein were found. Of serum immunoglobulins, IgM was increased markedly with 3,946 mg/dl and about 30% atypical lymphocytes were noted in the bone marrow. Bilateral tonsillectomy was carried out. The diagnosis of malignant lymphoma, non-Hodgkin, follicular, medium-sized cell type, B cell (sm IgM, K) was made by immunostaining of tissues. Chemotherapy was made after operation, and IgM levels decreased gradually. At present, the patient is following a satisfactory postoperative course, showing no swelling of tonsil.

Chimera states occur when identically coupled groups of nonlinear oscillators exhibit radically different dynamics, with one group exhibiting synchronized oscillations and the other desynchronized behavior. This dynamical phenomenon has recently been studied in computational models and demonstrated experimentally in mechanical, optical, and chemical systems. The theoretical basis of these states is currently under active investigation. Chimera behavior is of particular relevance in the context of neural synchronization, given the phenomenon of unihemispheric sleep and the recent observation of asymmetric sleep in human patients with sleep apnea. The similarity of neural chimera states to neural "bump" states, which have been suggested as a model for working memory and visual orientation tuning in the cortex, adds to their interest as objects of study. Chimera states have been demonstrated in the FitzHugh-Nagumo model of excitable cells and in the Hindmarsh-Rose neural model. Here, we demonstrate chimera states and chimera-like behaviors in a Hodgkin-Huxley-type model of thermally sensitive neurons both in a system with Abrams-Strogatz (mean field) coupling and in a system with Kuramoto (distance-dependent) coupling. We map the regions of parameter space for which chimera behavior occurs in each of the two coupling schemes.
