Abstract
Introduction: Cisplatin is a drug widely used as an antineoplastic drug for treatment of malignant tumors. But because of its side effects on the different systems especially kidney (nephrotoxic), the use of this drug is very limited. Clinical as well as, laboratory animal studies have supported this observations. In this research study we have used stereological technique (3-D) for finding the changes, due to nephrotoxic effect of this drug, in the number of glomeruli in kidney (numerical density and total number).
Materials and Methods: For experimental, 30 rats were separated by random sampling in to 3 groups of 10 animals cache. The first group received acute dose (7.5 mg/kg) of the drug (cisplatin) in serum physiology (experimental group). The second group received equivalent placebo dose in serum physiology through peritoneum (control). The third group received chronic dose (1.25 mg/kg) for 5 days, in serum physiology. All the 30 animals, after 96 hours, were anesthetized, dissected and their right kidneys were removed and placed in fixative (10% formalin). Whole kidney specimens were processed for stereology by special method of sectioning for physical disector and glomeruli number were counted.
Results: Number of glumeroli and numerical density was estimated for experimental groups (control, acute and chronic) was 31707, 30415 and 30802 as well 162, 119, and 140 respectively.
Conclusion: Stereological methods could be very useful for investigation of chemical drug effects in organs with good validity.

Abstract
Background: The theory of mind acts as an umbrella which covers the perception of children of others’ mental conditions under its banner and paves the way for child’s social cognition. This study was designed to compare the effects of different variables such as intelligence quotient (IQ), sex, age, and mental maintenance on the theory of mind development levels in autistic and normal children. Materials and Methods: In this case-control study, 19 autistic and 19 normal children were selected based on the in-reach sampling procedure and were also matched by age. The participants completed Wechksler intelligence scale for children, Stimman theory of mind task, and mental maintenance task. Results: In comparison to normal children, autistic children showed a clear deficiency in their theory of mind development levels however, age did not have a significant effect in this regard. Conversely, IQ and sex had significant impacts on the development of theory of mind. In addition, mental maintenance, alone, had a significant effect on the theory of mind. Conclusion: Noticing the existence of some primary levels of theory of mind in autistic children, some aspects of theory of mind can be compensated for through the provision of basic instructions and guidelines for development of intellectual and cognitive abilities in early childhood and primary stages of diagnosis.
