CA-125 is the most commonly used tumor marker in ovarian cancer, its known as the "Gold Standard" for the diagnosis of ovarian cancer. CA-125 allegely related to the inflammatory mechanisms which associated with leukocytes and lymphocytes, as well as Lymphocyte Platelet Ratio. This study is to prove above hypothesis. The objective is to investigate CA-125 correlation as tumor marker of inflammatory hematology examination which consisting of Hemoglobin, leucocytes and PLR as indicator of inflammatory examination in ovarian cancer patient. The method is an observational analytic study with cross sectional retrospective descriptive. The sample is 42 patients medical record who are treated in Oncology Polyclinic RSUD ULIN in October 2014 - October 2017 period. Samples selected by time limitation method. Sampling technique using nonpropability method followed by purposive sampling method. After the data is taken and selected then processed into SPSS for normality test and continued by multiple linear regression test. The results showed that correlation analysis of CA-125 tumor marker on Hb, leukocyte and PLR levels was P = 858b; P value <0.05. The CA-125 relationship to Hb, leucocytes and PLR is a negative relationship (r Hb = -3,463, r leukocytes = -6,117, r PLR = -2.281), which means that more high the Hb, leukocyte and PLR value, conversely CA125 value become more low. The conclusions of this study is there no correlation of CA125 tumor marker against Hb, leucocytes and PLR in ovarian cancer patients. The results of this study indicate that the increasing of CA125 value is negative correlation because it is not followed by decreasing of Hb, increasing of leukocyte and PLR.

In the present study and research work, land suitability evaluation (qualitative classification) was made for the Bilverdy research station of the Islamic Azad University in East Azarbaijan for wheat, barley, alfalfa, maize and safflower. The Simple Limitation Method (SLM), the Limitation Method regarding Number and Intensity (LMNI) and the Parametric Methods (PM) such as the square-root and the Storie methods were used. The landscape, climate and soil and characteristics that influence suitability of the land for particular crops have been combined according to the adopted methodology. Economic factors were excluded and moderate level of management was assumed. The results of different methods show that the most important limiting factors are climate, pH, organic matter (OM), gravel, salinity and sodicity, taken either alone or in combination. For safflower, the cation exchange capacity (CEC) can be added to these factors. Evaluation by the SLM and LMNI methods result in similar suitability classes, which confirms previous findings by other researchers for the same crops. However, in many cases the use of parametric methods, especially the square-root method, turned to be more realistic in distinguishing separate suitability classes. This study not only compares different methods and their results but also evaluates the suitability of the study area for particular crops. According to the square-root method, the area can be recommended as marginally suitable for cultivation of wheat, barley, alfalfa and safflower and is expected to yield about 40–65% of optimal production.

In this study appraisal of four different agricultural land evaluation methods including the so-called Storie method, square root method, maximum limitation method and fuzzy sets method, was done. The study was performed in Bastam region, located in Semnan province at the north east of Iran.<strong> </strong>Three crops including tomato, wheat and potato were assessed for the purpose of this research. Soil characteristics assessed were rooting depth, CaCo<sub>3, </sub>organic carboncontent, clay content, pH and slope gradient. Statistical analyses were done at significance levels of <em>α </em>= 0.1 and <em>α</em> = 0.05. Results of regression between land indices, calculated through the four methods, with observed yields of the crops, showed that the regression were significant in fuzzy sets method for all of the assessed crops at <em>p </em>= 0.05 but not significant in maximum limitation method for any of the crops. The Storie and square root methods also showed a significant correlation with wheat yield at <em>p </em>= 0.1. This study was a demonstrative test of fuzzy sets theory in land suitability evaluation for agricultural uses, which revealed that this methodology is the most correct method in given circumstances.
