[Study of curriculum changes and sequance of anatomy courses on medical students score of Esfahan medical sciences university]

Studdy of Curriculum Changes and Sequance of Anatomy Courses on Medical Students Score of Esfahan Medical Sciences University The midterm scores of two groups of medical students both engaged in learning the trunk anatomy and embryology were statistically compared simultaneously. Difference between two groups were as follows: One group had passed limbs anatomy units in previous term, and another group had not passed any anatomy course. The mid scores of the group one in trunk anatomy were 40/03 +/- 6/34 [of 65] and in embryology were 28/16 +/- 7/22 [of 50] and these scores in group two were 36/64 +/- 7/23 and 27/8 +/- 7/66 respectively. P value of compared scores were p <000 in both trunk anatomy and embryology. The meaningful difference between two groups scores is mainly due to familiarity of the first group with anatomy nomenclature and skill of three dimensional in carnation obtained during learning the limb anatomy. Although the trunk anatomy and neuroanatomy seems to be the most useful and the most interesting parts of curriculum for medical students, beginning of the curriculum with these two subjects without Any preliminary introduction to anatomy my be difficult and exhausting. Therefore it is better to taking limb anatomy course or having some types of introduction to anatomy before beginning of these two very important subjects

relationship between sperm protamine aberrations with protamine P1/ protamine P2 ratio

The aim of this study was to evaluate the relation between protamine deficiency assessed by CMA3 and protamine 1/ protamine 2 [P1/P2] ratio. This study was carried out on 71 patients referring to Isfahan Fertility and Infertility center. Semen analysis was assessed according to WHO criteria. CMA3 staining was use to determine protamine deficiency. P1/P2 ratio was evaluated by nuclear protein extraction, acetic acid urea poly acrylamide gel-electrophoresis and analysis of protein bands with related software. Western blot was carried out with primary anti P1 and anti P2 antibody to determine protamine 1 and protamine 2. Of the 71 patients 45 patients underwent Intracytoplasmic Sperm Injection [ICSI]. A negative significant correlation was observed between fertilization rate with protamine deficiency and P1/P2 ratio. However, no significant correlation was observed between protamine deficiencies with P1/P2 ratio. The results of this study showed that protamine deficiency can be assessed by CMA3; however this procedure does not indicate type of protamine deficiency
