No congenital anomaly has more complexity and diverse morphologic influence in the oral and maxillofacial region than cleft lip and palate. It has been said that it is the most common congenital craniofacial anomaly(with an occurrence of about 1 in 800 to 1000 live births). Essentially, cleft anomaly is a congenital disorder, and its etiology is considered to be multifactorial. The common characteristics of the cleft palate patients are lack of tissue, deviated muscle function, dental arch collapse, malaligned teeth and midface hypoplasia, because of the nature of the deformity and its associated irregularties, a cleft palate patient must be treated via a multidisciplinary approach. The orthodontist should play the role as a consultant for the total care of the cleft palate patients.

This study was to verify that the uptake inhibition and accumulation of nitrogen in different potassium levels. Lettuce was used as model plant in this study and grown in pot of 10cm’s in diameter and depth with mixture media of vermiculite and perlite under supply of different culture solution for three weeks. Nitrogen absorption at root was inhibited by increased potassium concentration in nutrient solution, and nitrate accumulation of plant was depended on absorption of nitrogen because nitrate content of 0 K level was 4-5 times higher than that of 2 K level, Concentration of ascorbic acid was decreased by increasing the nitrogen absorption, since ascorbic acid (AsA) content of 2K level was higher than those of 0K level in both of old leaf and flesh leaf.

Random copolyesters were prepared from poly (ethylene terephtalate) (PET) oligomer and 1,3-propanediol (PG) by polycondensation procedure using varying amounts of PET oligomer and PG. Copolymer compositions have been identified by $^1$H-NMR spectroscopy. The compositions of the copolymers can be conveniently controlled by manipulation of the reaction conditions. Three hour polymerization at 26$0^{\circ}C$ generated the copolymers with the highest intrinsic viscosity. Investigation of the thermal properties of the obtained polymers via DSC showed that the copolyester became completely amorphous when the composition of PG ranged from 30 to 65%. Sequence information of the produced copolyesters were obtained from $^{13}C$-NMR analysis. The ET-TP-ET and TT-TP-TT blocks could be distinguished from the unsymmetrical diester sequence ET-TP-TT. The sequence analysis indicates that all the studied copolymers have randomly distributed sequence structure.
