As one of measures to improve the environment in an automobile, Malodor caused by the automobile air conditioner evaporator was evaluated and analyzed using lab-scale test bench. The odor was simulated with an evaporator test bench equipped with an airflow controller, air temperature and relative humidity controller. To simulate the same characteristics of odor used to occur from automobiles, one used automobile air conditioner evaporator associated with unpleasant odors was selected. The odor was evaluated by trained panels and sampled with aluminium polyester bags. Samples were analyzed by thermal desorption into a cryotrap and subsequent gas chromatographic separation, followed by simultaneous olfactometry, flame ionization detector and identified by mass spectrometry. Because compounds are concentrated before thermal desorption, such sample as odor from evaporator was able to detect trace compounds participating in odor. Compounds such as aromatic hydrocarbons, alcohols, aldehydes, and organic acids were identified. GC/FID/Olfactometry combined sensory method with instrumental analysis was very effective for odor evaluation method in an automobile air conditioner evaporator.

Several studies have shown that patients with rheumatoid arthritis(RA) have a doubled to tripled increased risk for developing lymphomas compared with the general population, Indeed, primary testicular lymphoma accounts for about 1% of all lymphomas. We present a case of RA with primary testicular lymphoma treated with rituximab. A 67-year-o1d man was admitted due to aggravated polyarthralgia and morning stiffness. hIe was diagnosed testicular diffuse large B cell lymphoma (DLBCL) and done orchidectomy last year. There was no adjuvant chemotherapy nor radiotherapy because of patient's loss. Abdominal computed tomography (CT)scan showed about 6x4cm mass on the left adrenal gland. Malignant lymphoma (DLBCL) was proven by CT guided needle biopsy and he was treated with CHOP (cyclophosphamide, hydroxydaunorubicine, oncovin, prednisone) and rituximab (375㎎/㎡) combination regimen. After two cycle treatment, the clinical symptoms and laboratory data improved.
