[2-dimensional gel electrophoresis on protein patterns from suspension cultures of Taxus cuspidate induced by SA].

The permeability of cell membrane was enhanced by exogenous SA in the culture of Taxus cuspidata. Nuclei condense and fragments were observed in some cells by using fluorescent microscope, and the degraded chromosomal DNA was observed by using agarose gel electrophoresis. The changes in soluble proteins of the suspension cultures of Taxus cuspidata induced by salicylic acids were analyzed by using two-dimensional polyacrylamide gel electrophoresis. Comparing with the control, seven new protein spots were found and six protein spots were not found in the cultures grown with SA at 48h. The results obtained showed that SA could induce the expression of some special proteins that might be related with the action of SA in the suspension cultures of Taxus cuspidata.

[Aortic regurgitation caused by quadri-cuspid aortic valve].

Authors report the surgical treatment of a rare malformation of the aortic valve associated with coronary artery stenosis. The aortic valve had a supernumerary cusp which was revealed intraoperatively. The supernumerary cusp appeared to be similar in size to the three other. Surveying the literature it is stated, that the number of similar entities are about 50 in number. Autopsy findings note, that the prevalence is about 0.008-0.012%. During the past 25 years, in aortic valve replacement cases such entity could have not been explored. The possible significance of the entity lays in--that without rheumatic or degenerative origin-in the life span (above 40 years of age) it may lead to severe regurgitation leading to functional deterioration.
