Abstract

Cadmium is a highly toxic element that can be ingested or inhaled from a variety of industrial and dietary sources. Tannic acid (TA) is a plant polyphenol found in many dietary plant materials such as grain sorghum, coffee, tea and cocoa. The purpose of this study was to investigate the role of tannic acid against cadmium acetate induced toxicity in female rats.Three groups of adult female rats were treated orally with normal saline (0.09 Nacl) as a control group, 200 ppm cadmium acetate (first treated group), and 200 ppm + 200 ppm tannic acid (second treated group) for 12 weeks. The results indicated that cadmium acetate caused a significant decreased in RBCs count, Hb concentration, and PCV of female rats compared with control group, while that tannic acid enhanced these parameters. Also, the results showed that cadmium acetate induced a significant alternative in total and differential count of WBC, while these changes were attenuated by the tannic acid administration. Total protein and albumin were decreased significantly in female rats treated with cadmium, while there was non significant differences between these parameters in control female rats compared with Cd + TA treated rats. AST, ALT, ALP, Cholesterol, and TG were increased significantly in cadmium treated rats, but these values were decreased according to (TA) administration.

Correction for multicollinearity between the explanatory variables to estimation by using the Principal component method

Ali Areef

Pages: 145-151

Issues

Abstract

In the most of applications of regession ,no explanatory orthogonal will exist,but it is connected too strongly to the extennt that the results would be far from being exquisite. So its too difficult to expect the effects upon the individual variabls within the range of regression equation .Also the values estimated here concerning the factors could be slight in data. The non-orthogonality is said to be the problem of multicolinearity going side by side with the factors of unstable,estimated regression. This case,however,comes out from the strong linear relation between explanatory variants.To solve this problem, a method of the pricipal components is used;that which depends upon the fact that each linear type mihgt be reformulated as to the group of the orthogonal,explanatory variables; these in turn can be obtained as linearstructures for the orthogonal (basic) explanatory variables through the Barr'let norm,as a test formula, as away to know whetherthe roots possess a sufficient quality for a linear relation As for the practical side,or applied of this research concerning the special
data of the consumption of the individual in USA as dependent variable and wage income,non wage-non farm income,farm income are explanatory variables.the characters rootindicated to the collinearity ; the result is that the four variables can be treated as two factors only ,a ststistical programme is here used that is (SPSS,Minitab) for the analysis of the data.
