The powdered roots of moghat (Glossostemon bruguieri) have been traditionally used in Eastern countries for their nutritive and therapeutic value. However, the biological effects of the plant constituents have not been proved on the basis of scientific research. The present study aimed to evaluate the content and composition of proteins and mucilages of the roots and seeds of moghat, as well as the hypoglycemic effect of the mucilages. The crude protein constituted 19.5% of the seeds, while it made up 4.5% of the peeled dried roots of Glossostemon bruguieri (Moghat). Glutamic acid, proline, leucine, phenylalanine, histidine and arginine were abundant in the protein of both plant parts; 72 and 83%, respectively. Valine, cysteine, methionine and lysine were detected only in seed protein. Molecular weights of the seed proteins were 50,000, 45,000 and 22,000. Moghat seeds contained 5.0% mucilage, while 15.75% and 29.60% were recorded in roots of one- and two-year-old plants, respectively. GLC investigation showed that both these plant parts contained rhamnose, xylose, mannose and galacturonic acid. Arabinose (1.8%) and glucuronic acid (14.6%) were present only in the seeds, while galactose constituted 33.7 to 34.5% of the root mucilage. Age of the roots was reflected in quantitative differences rather than qualitative ones. The root mucilages had remarkable hypoglycemic activity, decreasing the blood glucose level in diabetic rats by 54.5% within 15 days. Accordingly, moghat roots should be investigated as potential medical and nutritive food.
PURPOSE: This study evaluated the effects of four adhesive primers on the shear bond strength of a self curing resin to cobalt-chromium alloy. MATERIAL AND METHODS: The adhesive primers Acryl Bond (AB), Cesead Opaque Primer (COP), Metal Primer II (MPII), and MR Bond (MRB) were used. A brass ring placed over the casting alloy disk surface nonprimed or primed with each primer was filled with the self-curing methyl methacrylate polymethyl methacrylate resin. The specimens were stored in water at 37 degrees C for 24 hours and then alternately immersed in water baths at 4 degrees C and 60 degrees C for 1 minute each for up to 20,000 thermal cycles before shear mode testing at a crosshead speed of 0.5 mm/min. RESULTS: All the primers examined improved the shear bond strength between the resin and cobalt chromium alloy compared with nonprimed specimens before thermal cycling. However, after 20,000 thermal cycles, the bond strengths of resin to cobalt chromium alloy primed with COP or MPII primers were significantly greater than those of specimens primed with AB or MRB primers and nonprimed controls. CONCLUSION: This study indicated that COP and MPII are effective primers to obtain higher bond strength between resin and cobalt-chromium alloy.
