Noccaea caerulescens (NC) and Arabidopsis halleri (AH) were studied to compare cadmiunm (Cd) accumulation and resistance. After 30, 60 and 90 days of plant cultivation in Cd contaminated soil (Cd1 = 30, Cd2 = 60 and Cd3 = 90 mg Cd/kg soil) amino acids were determined in plants. The comparison between both species showed that Cd stress resulted in different changes of amino acids levels playing a significant role in plant adaptation to Cd stress. Our analyses indicated higher accumulations of amino acids in the roots of NC compared to AH. Contrasting responses of plants to Cd contamination were confirmed in methionine metabolism. Methionine was determined only in roots of AH after 30 and 60 days of plant cultivation. Free methionine content decreased with increasing Cd contamination (Cd3 treatment – 40% decrease compared to the control treatment). Our results also showed that NC contains more than 10-fold higher content of histidine than AH. These observations indicated that this amino acid may be involved in Cd resistance and accumulation by reducing oxidative damage. Tryptophan plays a major role in the regulation of plant development and in defense responses. Its significant increase for NC treatments in contrast to AH treatments was determined.

SummaryThe effects on blood flow and plasma fibrinolytic and coagulation parameters of intraarterial substance P, an endothelium dependent vasodilator, and sodium nitroprusside, a control endothelium independent vasodilator, were studied in the human forearm circulation. At subsystemic locally active doses, both substance P (2-8 pmol/min) and sodium nitroprusside (2-8 μg/min) caused dose-dependent vasodilatation (p <0.001 for both) without affecting plasma concentrations of PAI-1, von Willebrand factor antigen or factor VIII:C activity. Substance P caused local increases in t-PA antigen and activity (p <0.001) in the infused arm while sodium nitroprusside did not. At higher doses, substance P increased blood flow and t-PA concentrations in the noninfused arm. We conclude that brief, locally active and subsystemic infusions of intraarterial substance P cause a rapid and substantial local release of t-PA which appear to act via a flow and nitric oxide independent mechanism. This model should provide a useful and selective method of assessing the in vivo capacity of the forearm endothelium to release t-PA acutely.

Pain and inflammation are the basic defense responses of the body that the result of the injury and any other damage to the body. During the years the concerns were raised towards the inflammation that is caused to the oxidative damage that is resulted in the physiological stress due to oxidation. There are a lot of drugs that are used to treat the condition effectively and the typical examples are NSAID’s and SAID’s which have a noted mechanism to show the anti-inflammatory activity. They have serious problems with the side effects like Gastrointestinal irritation, Gastric pain, Gastric perforations and peptic ulcers. Herbs have been used as better alternatives that are used to treat diseases. The significance of the medicinal plants had been emphasized significantly in tradition rich countries like India and all over the world. The research proof of those herbs for their activities and their traditional claims were proven. Poly Herbal Gels were prepared using the root extracts of the plant Corchorus olitorius. The gels were prepared using the Carbopol 940 and the prepared gels were investigated for their anti-inflammatory property and the gels showed a significantly better activity compared to the plant extract and the standard drug too. The addition of other drugs in to the gels added and advantage to the increase in the activity and faster onset of action as the gel was applied directly in the place of the inflammation.
