Résumé
Reported here is a case of pheochromocytoma arising from an accessory adrenal gland. This tumor did not have significant clinical symptoms related to pheochromocytoma. The chief complaint was intermittent left upper quadrant pain. Scintigraphy of the abdomen identified normal bilateral adrenal glands, and a 56×63 mm tumor, adjacent the distal part of pancreas. The resected tumor was located between pancreas and spleen and was composed of normal adrenalortical tissue and pheochromocytoma. Immunohistoche-mical staining of tumor for KI67, chromogranin A, NSE, S100 and AE1 was positive. Pheochromocytomas, arising from an accessory adrenal gland, may lack some of the typical characteristics of such tumors and have rarely been reported

Different time series analysis of daily air pollution of Isfahan city were performed in this study. Descriptive analysis showed different long-term variation of daily air pollution. High persistence in daily air pollution time series were identified using autocorrelation function except for SO[2] which seemed to be short memory. Standardized air pollution index [SAPI] time series were also calculated to compare fluctuation of different time series with different levels. SAPI time series indicated that NO and NO[2], CH4] and non-CH[4] have similar time fluctuations. The effects of weather condition and vehicle accumulation in Isfahan city in cold and warm seasons are also distinguished in SAPI plots
