N-(4-羧基苯基)维甲酰胺对交链孢醇单甲醚致突变性的抑制(摘要)

互隔交链孢霉在食管癌高发区林县粮食中污染严重,交链孢醇单中醚(Alternariol Monomethyl Ether,AME)是互隔交链孢霉提取物分用纯化获得的一种有效成份,为该霉菌的主要代谢产物之一。实验证明在不加s-9时,AME诱发了6-巯基鸟嘌呤抗性(6-TG~r)的V_(79)细胞突受,具有直按致突变性,可能对食管癌发病起一定作用。     

甲亢性周期麻痹23例分析

目的：探讨甲亢性周期性麻痹（TPP）的临床特点。方法：对23例TPP进行回顾性分析和总结。结果：TPP占同期住院甲亢患者的6.2%,男女比例22∶1,21-40岁为发病高峰年龄,肌无力发作时23例血钾均低于正常。结论：TPP以肌无力伴低钾血症为其临床特点,及早诊治是关键。TPP患者的治疗应在补钾的同时加用抗甲状腺药物,可减少复发。对重度TPP进行心电监护、补钾、抗心律失常和呼吸机辅助呼吸是抢救成功的重要措施。     

宫腔镜引导疏通输卵管治疗阻塞性不孕

低蛋白饮食对环孢素A肾病大鼠肾间质纤维化的作用

Objective To investigate whether low-protein diet has protective effect on the progression of renal interstitial fibrosis in rats with cyclosporine A (CsA)-induced nephropathy. Methods Eighteen male Sprague-Dawley rats were randomly divided into three groups (6 rats in each group). The rats in control group (C group) received common diet; in model group (M group) low-salt diet; in intervention group (Ⅰ group) low-salt and low-protein diet. After diet adaptation period of one week, the rats in C group received subcutaneous injection of olive oil 1 mg/kg daily for 5 weeks, while M group and Ⅰ group subcutaneous injection of CsA (diluted into 25 g/L with olive oil) 1 ml/kg for 5 weeks. All the rats were sacrificed at the end of the 5th week. The food-intake and body weight were measured daily. The creatinine clearance (Ccr) was examined before rats were sacrificed. The semi-quantitative pathological analysis on kidney sections was performed. The mRNA and protein expression of transforming growth factor-β1 (TGF-βI) and type Ⅰ collagen (Col Ⅰ) in kidney tissue was determined with real time PCR and immunohistochemical staining, respectively. Results The food-intake and body weight of rats in M and I groups were significantly lower than those in C group (P<0.05). Compared with C group, the Ccr levels in M and Ⅰ groups were significantly reduced [(0.65±0.15) ml/min, (0.40+0.13) ml/min vs (1.55±0.29) ml/min, P<0.05], the relative fibrosis areas of kidney interstitium in M and I groups were significantly increased (3.60%±0.46%, 3.26%±0.75% vs 0.44%±0.24%, P<0.05), the mRNA and protein expression of TGF-β1 in M and I group was significantly up-regulated (by 2.6 and 3.1 times in mRNA and by 1.5 and 1.6 times in protein, respectively, P<0.05), and the mRNA and protein expression of Col Ⅰ in M and I groups was also significantly up-regulated (by 3.0 and 3.5 times in mRNA and by 2.3 and 2.1 times in protein, respectively, P<0.05). There were no significant differences between M and I groups in every parameters above-mentioned except the rat body weight and Ccr. Both the body weight and Ccr in Ⅰ group were significantly lower than those in M group (P<0.05). Compared with C group, the urine osmotic pressure in M group and in I group were deceased (for M group, P>0.05; for I group, P<0.05). Compared with C group, the serum cholesterol levels in M and I groups were significantly increased (P<0.05), and the serum phosphorus level in I group was significantly decreased (P<0.05). The levels of serum albumin and serum calcium of all three groups had no statistical differences (P>0.05). Conclusion Low-protein diet has no renoprutective effects on the rat model of cyclosporin A nephropathy, on the contrary, may induce body weight loss.

丹参注射液对自发性高血压大鼠左室肥厚的影响

目的：探讨丹参对自发性高血压大鼠（SHR）左室肥厚的影响。方法：18只引种繁殖的雄性SHR随机分成三组，每组6只。对照1组育至第8周处死；丹参组从第8周给药，丹参粉针剂1g／（kg.d），腹腔注射，用药10周处死；对照2组从第8周开始用相同容量蒸馏水腹腔注射，第18周处死。测量各组大鼠尾动脉收缩压（SBP）及左心室重量指数（LVMI），应用HE、VG染色，结合计算机图像分析技术，检测心肌细胞的直径（TDM）和面积（CA）、心肌组织胶原体积比例（CVF）、血管周围胶原面积与管腔面积比例（PVCA）。三组间各指标进行显著性检验。结果：与对照1组比较，对照2组的SBP、LVMI、TDM、CA、CVF、PVCA显著增加；丹参组除SBP升高外，余指标与对照1组比较，无统计学意义；与对照2组比较差异有显著性意义，P〈0.05。结论：丹参注射液能预防自发性高血压大鼠左室肥厚的形成。
