Extracts of Monascusus Purpureus beyond Statins——Profile of Efficacy and Safety of the Use of Extracts of Monascus Purpureus

Monascus purpureus is a fungus that has been tradi-tionally used in China for thousands of years to produce ricewine . Traditionally the fungus is used to ferment non-gluti-nous cooking of rice ,to produce a kind of famous red ricewine .Its main traditional indications consist of disordersdue to the accumulation of fats (nosologically linked withthe problems of stasis of circulation in traditional Chinesemedicine) ,liver disorders and some forms of tumor as ithelps i mprove the circulation of …     

Sexual precocity: sex incidence and aetiology

The aetiology of 197 girls and 16 boys presenting with sexual precocity was reviewed. Ninety one girls and four boys had central precocious puberty (M:F 23:1); a cause was identified in all the boys but in only six girls. All boys with precocious puberty need detailed investigation; in girls investigation should be based on clinical findings, particularly the consonance of puberty.     

显微注射后家兔转基因受精卵的体外培养和移植成活率的观察研究

目的：研究家兔受精卵经显微注射转基因过程的耐受性，建立转基因动物技术平台。方法：(1)家兔超数排卵诱导；(2)对2000个家兔受精卵进行显微注射技术操作；(3)对1280个受精卵进行显微注射后体外培养观察；(4)216个注射后受精卵向13只受体母兔输卵管进行移植．结果：(1)经显微注射后受精卵进行体外培养有68％的受精卵能够发育至桑椹胚和囊胚；(2)目前有7只受体母兔经输卵管转基因受精卵移植分别产下3，4，5，2，6，13，7只仔兔。结论：(1)受精卵能够在体外经受显微注射转基因过程的损伤，但暴露于体外的操作时间应尽可能的缩短；(2)显微注射操作技术的熟练程度是实验成功的关键。     

同种异体原位心脏移植术后心电图分析

目的：探讨同种异体原位心脏移植术后患者的心电图改变特点，方法：对3例心脏移植的患者术后分别进行体表12导联心电图跟踪观察，主要观察心率、心律、ST-T演变情况，结果：共同表现的ST段抬高系心肌再灌注后损伤性改变，不完全性右束支传导阻滞与手术中机械刺激或损伤有关，由于去神经作用心率变化较小，应用标准术式患者易出现心律失常，应用双腔静脉原位心脏移植术后心律失常发生率较少，结论：心脏移植术前、术后心电图追踪观察有助于指导治疗和评估预后。     

Physicochemical properties of valsartan and the effect of ethyl alcohol, propylene glycol and pH on its solubility

The aqueous solubility and partition coefficient of valsartan were determined at room temperature. The effect of ethyl alcohol, propylene glycol and pH on its solubility was also investigated. It was found that both solvents increased the solubility of the drug in water. The solubilizing power of ethyl alcohol was found to be higher than that of propylene glycol. Valsartan solubility was also observed to increase at high pH values and its lipophilicity wasdemonstrated by the high positive value of the logarithm of partition coefficient.     

Effect of electrolytes on the partition coefficient of irbesartan

The effect of various electrolytes namely monovalent, divalent and trivalent on the partition coefficient of irbesartan between n-octanol and water systems was investigated at room temperature. It was found that all the electrolytes increase the partition coefficient of irbesartan. The uptake of irbesartan by the organic phase from the aqueous phase is increased with increasing salt concentration except for potassium iodide and aluminum chloride. The effect was found to depend on the size and charge of the ions present in solution.     

An antimalarial extract from neem leaves is antiretroviral

An acetone-water neem leaf extract with antimalarial activity was evaluated in vitro at 5 microg/ml for inhibition of adhesion of malaria parasite-infected erythrocytes and cancer cells to endothelial cells, and at 10 microg/ml for protection of lymphocytes against invasion by HIV. The extract was also evaluated in 10 patients with HIV/AIDS at 1000 mg daily for 30 d. The mean binding of infected erythrocytes and cancer cells per endothelial cell was 15 and 11 respectively in the absence of the extract, and 0 and 2 respectively in with the extract. In the absence and presence of the extract, 0% and 75%, respectively, of lymphocytes were protected. In the treated patients, haemoglobin concentration, mean CD4+ cell count and erythrocyte sedimentation rate, which were initially 9.8 g/dl, 126 cells/microl and 90 mm/h respectively, improved to 12.1 g/dl, 241 cells/microl and 49 mm/h. Mean bodyweight and platelet count, initially 57 kg and 328 x 10(3)/mm3 respectively, increased to 60 kg and 359 x 10(3)/mm3. No adverse effects were observed during the study. The extract showed antiretroviral activity with a mechanism of action that may involve inhibition of cytoadhesion. The results may help in the development of novel antiretroviral and antimalarial drugs.
