Objective To investigate the CT and MR] features of basal cell adenoma of the parotid gland. Methods CT and MRI features of 9 basal cell adenoma cases (4 men and 5 women, median age 58) confirmed by operation and pathology were reviewed retrospectively. All CT and MR images were retrospectively evaluated with respect to location, size, morphology, margin, CT density/MR] signal intensity and enhancement behavior. Results Each of the 9 patients had only 1 tumor. Eight lesions were located in the superficial lobe and 1 in the deep lobe. Seven tumors were round without lobular appearance, and 2 tumors were elliptic with small lobular appearance. All the 9 lesions were well circumscribed with smooth contours. A capsule-like rim with low intensity on MR[ was observed in 2 lesions, and a rim with high intensity on T1 WI and T2 WI was detected in another lesion. These 3 lesions showed low intensity on T1 WI and T2 WI with heterogeneously strong enhancement and delayed enhancement. Four lesions showed cystic areas in the center with mural nodules on CT, which were moderately or obviously enhanced (the mean increase of CT values: 65.5 H U ), and 2 lesions showed homogeneous enhancement. Conclusion Basal cell adenoma of parotid gland should be first considered when the old women had single round lesion located in the superficial lobe with smooth contour and low intensity on T2WI, especially when cystic areas were observed in the center with mural nodules on CT/MR.

Objective To investigate the effect of lidocaine on the LPS-induced NF-κB activity in rat peritoneal macrophages. Methods The peritoneal macrophages obtained from male Wistar rats were placed in 12-well plates at 2 × 106 cell/ml after being cultured for 3 days. Each well contained 1 ml of cell suspension. The cells were randomized into control group (group C), LPS group and 3 LPS + lidocaine group S (group LL1.2.3)(n = 10 wells each). In group LPS and LL1,2,3, the cells were exposed to LPS 100 ng/ml. In group LL1,2,3 the cells were exposed to lidocaine 2, 20 200 kg/ml respectively in addition to LPS 100 ng/ml. After being incubated for 24 h, the HMGB1 concentration in the supernatant (by ElISA) and HMGB1 mRNA expression (by RT-PCR)and NF-κB activity in the cells were measured. Results LPS signiticantly increased HMGB1 concentration,HMGB1 mRNA expression and NF-κB activity in the supernatant. Lidocaine treatment significantly attenuated the LPS-induced increase in HMGB1 concentration HMGB1 mRNA expression and NF-κB activity in a dose-dependent manner. Conclusion Lidocaine can inhibit NF-κB activity in the rat peritoneal macrophages and in turn inhibit the synthesis and release of HMGB1.

Objective:To observe the effects of bama nectar in kidney-yang deficienct mice and on the mating ability and sperm counts of normal mice. Methods:The weight, body temperature, locomotor activity, cold-resistant,genital organ coefficient and lipid peroxidation of the hydrocortisone-induced kidney-yang deficient mice were detected. The genital organ ccoefficient, immune organ co-efficient and erectile function of the ovariectomized mice were detected. The mating ability and the sperm counts of normal mice were measured. Results:Compared with the model group, bama nectar obviously increased the weight, body temperature and locomotor ac-tivity of the hydrocortisone-induced kidney-yang deficient mice, and improved the locomotor activity, the organ coefficient of seminal vesicle, prostate gland, preputial gland and epididymis. Furthermore, bama nectar significantly increased the SOD activity in serum and reduced the level of MDA in serum when compared with the model group (P<0.05 or P<0.01). Compared with the model group, bama nectar could increase the organ coefficient of foreskin and thymus gland in the ovariectomized mice, and shorten the erec-tile latency (P<0. 05). Compared with the normal group, bama nectar improved the mating ability and the sperm counts of the male mice (P<0. 05 or P<0. 01). Conclusion:Bama nectar has beneficial effects on invigorating kidney and strengthening yang.

Objective To compare the value on assessment of perfusion weighted imaging (PWI) using Gd-DTPA and the superparamagnetic iron oxide (SPIO) particles (Resovist) in the experimental model of hyperacute cerebral infarction in rats. Methods Thirty Wistar rats were randomly divided into Group A and B (each n=15). After occluding the left middle cerebral artery with thread for 1 h in all rats, two dynamic MR perfusion imaging series were acquired after intravenous bolus injections of 8 μmol Fe/kg SPIO (Group A) and 0.2 mmol/kg Gd-DTPA (Group B), respectively. The doses were chosen to obtain similar maximum signal change in normally perfused brain. The perfusion imaging was compared between the region of interest (ROI) in the core area with severe ischemia and in the penumbra area of moderate ischemia. The parameters were compared between two groups with pathologic findings and TTC stain. Results The first-passage profiles were found to be similar for Gd-DTPA and SPIO, both in the core area with severe ischemia and in the penumbra area of moderate ischemia of rats models. No statistical difference of the parameters (CBV, MTT, TTP) of PWI for ischemic penumbra was detected between Group A and B. Conclusion The efficacy of the Resovist using in the MR PWI is similar to Gd-DTPA for diagnosis of the perfusion reduction in the rat stroke models. Strong susceptibility effects may be achieved with small injection volumes. Resovist may play an important role in MR PWI.
