Symmetrical lipomatosis is characterized by symmetrical infiltration of adipose tissue into the head, neck, or upper trunk. By contrast, oral involvement is extremely rare. The present report describes a case of symmetrical lipomatosis of the tongue (SLT) presenting as macroglossia. The patient was a 63-year-old Japanese male who developed progressive dysarthria secondary to enlargement of the tongue. The patient's medical history was notable for alcoholic hepatitis and hyperlipidemia. Marginal glossectomy was performed on both sides of the tongue to achieve volume reduction and restore normal speech. Histopathologic examination of the resected tissue revealed diffuse infiltration with adipose tissue lacking a fibrous capsule. The patient's postoperative course was uneventful, and he remained free of recurrence or regrowth and functional deficits at the 6-year follow-up time point.

OBJECTIVETo investigate anti-aging effect and mechanism of Cordyceps extract(CSE) on aged mice induced by D-galactose.
METHODThe aged mice were induced by D-galactose. Meanwhile, they were treated with three doses of CSE. Then the ability of learning and memory, the activity of antioxidase in the different tissue, the contents of MDA of brain and liver were measured after 6 weeks.
RESULTCSE could significantly increase the ability of learning and memory, improve the activity of SOD of red blood cells, brain and liver, the activity of Na(+) -K(+) -ATPE of brain, the activity of CAT and GSH-Px of blood, and remarkably decrease the activity of MAO of brain and the contents of MDA of brain and liver.
CONCLUSIONCSE has good anti-aging effects on the aged mice, which is probably due to effects of improving antioxidation and removing free radicals.

BACKGROUNDMultislice helical computed tomography (MSCT) has been used to depict coronary anatomy noninvasively, and proved useful for evaluating ventricular function. The aim of our study was to assess the accuracy of ventricular volume as measured by MSCT.
METHODSFourteen human left ventricular (LV) and 15 right ventricular (RV) casts were scanned by MSCT. A series of LV and RV short-axis images were reconstructed later with slice thickness of 2.0 mm, 3.5 mm, 5.0 mm, 7.0 mm, and 10.0 mm. Ventricular volume was calculated by the multislice tomographic Simpson's method. True LV and RV cast volumes were determined by water displacement.
RESULTSBoth calculated LV and RV volumes correlated highly with the corresponding true volumes (all r >0.95, P <0.01). But with slice thickness from 2.0 mm to 10.0 mm, MSCT scanning overestimated the corresponding true volume by (3.21 +/- 5.95) ml to (12.58 +/- 8.56) ml for LV and (10.22 +/- 8.45) ml to (23.91 +/- 12.24) ml for RV (all P <0.01). There was a very high correlation between the overestimation and the selected slice thickness for both LV and RV volume measurements (r=0.998 and 0.996, P <0.01, respectively). However, when slice thickness was reduced to 5.0 mm, the overestimation for both LV and RV volume measurements became nonsignificant for slice thickness from 2.0 mm to 5.0 mm.
CONCLUSIONSBoth LV and RV volumes can be accurately estimated by MSCT. Thinner slice has more accurate calculated volume. However, 5.0 mm slice thickness is thin enough for an accurate measurement of LV or RV volume.
