CA 125, CA 19-9 and CEA in benign gynecologic tumors: Effect of surgery

The present study showed that combining serum essay of CA125, CA19-9 and CEA is useful in the preoperative exclusion of malignancy in patients with ovarian tumors. A leiomyomas were associated with low levels of the 3 tumor markers, elevated levels particularly of serum CA125 may point to adenomyosis in patients with uterine mass. The results showed that the serum levels of the tumor markers were significantly decreased postoperatively. So, it can be safely assumed that the specificity of these tumor markers is not affected by abdominal surgery

Molluscicidal activity of sodium lauryl sulfate and the associated biochemical changes in the mollusc tissue

The molluscicidal activities of primary and secondary sodium lauryl sulphates are determined against Biom phalaria alexandrina snails. The maximim activity of each compound was respectively shown at 300 and 150 P.P.m. These molluscidies are also stable and fully active over a period of 48 hours. Their molluscidal activity was associated with some changes in the enzymatic pattern of the mollusc tissue homogenate. The advantages of these compounds are the availability, low cost, stability and safety to mammals and fish, render them valuable as possible molluscicides of economic importance
