Flavocoxid is as effective as naproxen for managing the signs and symptoms of osteoarthritis of the knee in humans: a short-term randomized,double-blind pilot study

Flavocoxid (Limbrel), a proprietary mixture of flavonoid molecules (baicalin and catechin), was tested against a traditional nonsteroidal anti-inflammatory drug, naproxen, for the management of the signs and symptoms of moderate osteoarthritis (OA) in humans. Discomfort and global disease activity were used as the primary end points, and safety assessments were also taken for both treatments as a secondary endpoint. In this double-blind study, 103 subjects were randomly assigned to receive either flavocoxid [500 mg twice daily (BID)] or naproxen (500 mg BID) in a 1-month onset of action trial. Outcome measures included the short Western Ontario and McMaster University Osteoarthritis Index, subject Visual Analogue Scale for discomfort and global response, and investigator Visual Analogue Scale for global response and fecal occult blood. Both flavocoxid and naproxen showed significant reduction in the signs and symptoms of knee OA (P ≤ .001). There were no statistically detectable differences between the flavocoxid and naproxen groups with respect to any of the outcome variables. Similarly, there were no statistically detectable differences between the groups with respect to any adverse event, although there was a trend toward a higher incidence of edema and nonspecific musculoskeletal discomfort in the naproxen group. In this short-term pilot study, flavocoxid was as effective as naproxen in controlling the signs and symptoms of OA of the knee and would present a safe and effective option for those individuals on traditional nonsteroidal anti-inflammatory drugs or cyclooxygenase-2 inhibitors. A low incidence of adverse events was reported for both groups.

四种中药对骨愈合过程中相关基因表达的影响

目的:探索中药水蛭、海螵蛸、阿胶、骨碎补在骨折愈合过程中的干预作用,了解它们各自的调节靶点,探索建构其基因组学的途径。方法:通过在大鼠胫骨打孔的方法建立单因素干扰模型,并将300只大鼠随机分为正常组、模型组和给药组(分别用4种中药给药),每组50只,分别在实验的第4、7、14、21、28天不同时间点采用原位杂交方法对各类mRNA的变化进行动态观察,分析骨愈合过程中Ⅰ、Ⅱ、Ⅲ型前胶原mRNA、转化生长因子TGF-β1mRNA、骨形态发生蛋白BMP-2mRNA以及血管内皮生长因子VEGF-mRNA的表达情况。结果:不同中药对不同基因的作用不同,作用的时间点不同,作用强度也存在差异。其中海螵蛸在骨折早期对Ⅰ、Ⅲ型前胶原mRNA、VEGF-mRNA、BMP-2mRNA的表达升高,后期Ⅱ、Ⅲ型前胶原mRNA表达水平下降,VEGF-mRNA、TGF-β1mRNA表达量维持于较高水平;骨碎补组较模型组在BMP-2mRNA、TGF-β1mRNA、Ⅰ型前胶原mRNA的表达上差异有显著性统计意义;阿胶对骨愈合早、中期Ⅰ、Ⅱ、Ⅲ型前胶原mRNA和TGF-β1mRNA的表达与模型组比较差异存在显著性统计意义;水蛭对VEGF-mRNA的表达具有一定的促进作用。结论:海螵蛸、水蛭对血管形成有促进作用,阿胶、骨碎补和海螵蛸对骨折软骨形成早期具有促进骨诱导的作用,并对成骨细胞的增殖及合成活性有较大影响。     

Seizures induced by aminooxyacetic acid in mice: pharmacological characteristics

Systemic (s.c.) administration of aminooxyacetic acid (AOAA) in mice triggered clonic convulsions with a CD50 (convulsive dose) of 68 mg/kg (range 54-86). AOAA also induced clonic convulsions in mice subjected to intracerebroventricular administration of the drug with a CD50 of 0.04 mumols (range 0.028-0.06). At the onset of convulsions induced by systemic AOAA (CD97;150 mg/kg), the GAD activity in the frontal cortex and hippocampus was not affected. GABA mimetic drugs, progabide and gabaculine, had no effect on convulsions induced by AOAA. Convulsions induced by systemic administration of AOAA were blocked by diazepam, phenobarbital, and valproate. Ethosuximide, trimethadione, acetazolamide, diphenylhydantoin, and carbamazepine remained ineffective. L-Phenylisopropyladenosine was also found to protect mice against AOAA-induced convulsions, whereas atropine and baclofen had no effect. The seizures induced by intracerebroventricular administration of AOAA (CD97; 0.1 mumols) were blocked by coadministration of preferential N-methyl-D-aspartate antagonists, D-(-)-2-aminophosphonoheptanoic (AP7), 3-[+/-)-2-carboxypiperazine-4-yl)-propyl-1-phosphonic (CPP), and kynurenic acid (KYNA); preferential quisqualate/kainate antagonists, 6-cyano-7-nitro-quinoxaline-2,3-dione and gamma-D-glutamylaminomethylsulphonic acid, remained inactive in the range of dosages sufficient to block seizures induced by quisqualic acid or kainic acid. The antagonistic action of antiepileptic drugs effective against seizures induced by excitatory amino acids (diazepam and valproate), and drugs acting on excitatory amino acid receptors (AP7, CPP, and KYNA) upon seizures induced by AOAA suggests an involvement of excitatory neurotransmission in the convulsant action of the drug.     

Gold complex research in medical science. Difficulties with experimental design

Despite the use of gold complexes in modern medicine for over 100 years and the use of gold complexes in the management of rheumatoid disease for more than 60 years, the definitive mechanisms of action for efficacy and for toxicity have not been established. Gold is a group 1b metal in the periodic table with several oxidation states but it is only Au(I) which is active in the biological milieu. Gold sodium thiomalate is not only a polymeric structure, but also has the chiral ligand, thiomalic acid. Gold sodium thiomalate thus can exist in several different physical states which may have different biological activity. In addition the pharmacokinetic profile of gold complexes has been of little value in the understanding of either the mechanism of action, efficacy or toxicity for both the injectable and the oral gold complexes. Many authors have misinterpreted research data on the activities of gold complexes because they compared gold complexes of different structures, and gold complexes which exist at different pH. Experimental work in our laboratory has identified that gold sodium thiomalate is a mixture and can exist as either a yellow or a colourless solution. These have some similar but several different biological activities. Many factors contribute to the lack of understanding of the action of gold complexes. Some of these factors are related to the wide variation in physical structure and biological activities exhibited by these compounds.
