患糖尿病有哪些蛛丝马迹？

典型的糖尿病患者常有“三多一少”的症状。但也有不少人无明显症状甚至毫无症状，在体检或作其他疾病检查时才被发现。其实，只要细心观察，也可以发现很多蛛丝马迹。

Ames试验检测三硝基甲苯及其还原代谢产物的诱变性

应用Ａｍｅｓ试验检测系统观察了三硝基甲苯及其还原代谢产物４－羟氨基－２，６－二硝基甲苯（４－ＨＡ），４－氨基－２，６－二硝基甲苯（４－Ａ），２－氨基－４，６－二硝基甲苯（２－Ａ）和２，４－二氨基－６－硝基甲苯（２，４－ＤＡ）的诱变活性，实验结果显示，三硝基甲苯及其代谢产物具有明显的致突变作用，４－Ａ的直接诱变活性最强，而且移码型诱变性更为显著，在微粒体酶系统的参与下，ＴＮＴ的诱变活性增强，其代谢产

不同液体术前急性高容量血液稀释对深静脉血栓病人血液流变学的影响

Objective To investigate the effects of acute hypervolemic hemodilution (AHH) with different fluids on blood rheology in patients with deep vein (femoral and iliac) thrombosis. Methods Thirty ASA I or II patients aged 40-64 yr who had developed deep vein thrombosis in 48 h and were scheduled for embolectomy were randomly divided into 3 groups ( n = 10 each) ; group I normal saline (NS) ; group II 6 % HES 200/0.5 ( HES) ; group IE gelofusine (GEL). AHH was performed with normal saline, 6% HES or gelofusine infusion at 20 ml·kg-1 ·h-1 for 40 min. MAP, HR and SpO2 were monitored. Blood loss, volume of blood transfusion and fluid infused and urine output during operation were recorded. Anesthesia was induced with fentanyl 3-5 fig/kg, etomidate 0.15-0.30 mg/kg, propofol 1-2 mg/kg and succinylcholine 1-2 mg/kg and maintained with 2% isoflurane and propofol infusion at 5-8 mg·kg-1·h-1 and intermittent iv boluses of vecuronium. The patients were mechanically ventilated (VT 8 ml/kg, RR 12 bpm). PaO2 and PaCO2 were maintained within normal range. Venous blood samples were obtained before and after AHH for measurement of hematocrit (Hct), whole blood viscocity (WBV) at low or high shear rates, plasma viscosity, RBC aggregation and RBC deformation. RBC aggregation index and RBC deformation index were calculated. Results MAP and HR were stable in all patients. The amount of blood transfusion and fluid infused was significantly less in group HES and GEL than in group NS. The WBV at low or high shear rates in group HES and GEL, Hct in all 3 groups and RBC aggregation index in group HES were significantly decreased after AHH, but the RBC deformation index was significantly increased in group HES. Conclusion Colloid is better than crystalloid and HES is better than gelofusine in improving intraoperative hypercoagulability and sluggish blood flow.

外用普萘洛乐乳剂产生皮肤银屑病样改变及骨化三醇对其影响的实验研究

将5％普萘洛乐乳荆外涂啄鼠耳都皮肤2周后·可引起皮肤银屑病样改变，表现为表皮角化过度．角化不全，棘细胞层增厚，基底细胞出现核分裂像，上皮脚下延，真皮内炎性细胞程润．如涂药前肌注骨化三醇，则上述改变明显减轻，但骨化三醇对未涂药组表皮无明显影响。结论：普萘洛乐可促进表皮异常增生，使之里银屑病样改变，骨化三醇则对其有明显的抑制作用。
