ABSTRACT
The present survey was carried out to determine the prevalence of human amebiasis. During the study, 1360 fecal samples were examined from February 2007 to December 2007 at Nishtar Hospital, Multan. Out of 1360 hosts examined, 295 were infected with E. histolytica. The overall prevalence of E. histolytica was [21.69%]. Relationship between sex and E. histolytica in humans showed that the infection of E. histolytica was more prevalent in male hosts [22.36%] as compared to female hosts [20.9%]. However the difference was statistically non-significant [P>0.05]. Results regarding the relationship between age and E. histolytica revealed that the parasite had highest prevalence [30.82%] in age group of 1 day to 15 years and lowest prevalence [17.34%] in age group of 31 to 45 years. The difference was statistically significant [P<0.05]

The aim of the present research was to study the effect of immediate vs. delayed knowledge of results on subsequent performance in verbal learning. A homogenous sample of 26 male and 26 female students was selected on the basis of their performance on Otis Quick Scoring Mental Ability Test, with their IQs ranging between 90-100. The test material consisted of a series of simple four digit mathematical [addition] problems used under two treatment conditions, i.e., "Immediate" and "Delayed" knowledge of results. T test was applied to test the significance of difference between the means of two groups. Hypothesis was duly supported, i.e., immediate knowledge of results tended to favour the subsequent performance of all subjects, with no significant difference between the performance of males and females taken separately
