Intelligence quotient analysis and its association with academic performance of medical students.

Background: Intelligence is the ability to see meaningful relationships between things that includes perceiving, knowing, reasoning and remembering. The study was done to know the duration of preparation, self study hours, academic performance and its association with IQ level of medical students, to state how to shorten the duration of completing MBBS degree. Methods: A cross sectional study done on 300 medical students using structured questionnaire derived from I Q test.com. Data collection and appropriate statistical test were applied considering p value ≤ 0.05 as significant. Results: Most of the medical students had near average intelligence (88.3%) , they undergone one to two years preparation for medical entrance exams and devoted much time (>6 hrs) in studies. 10% of the students had higher IQ, spare less time in their self study but were sincere in the classes. Conclusion: Students with near average IQ work hard in their studies and their academic performance was similar to students with higher IQ. So IQ can`t be made the basis for medical entrance; instead giving weight-age to secondary school results and limiting the number of attempts may shorten the time duration for entry and completion of MBBS degree.

Intravenous human umbilical cord blood improves elctrophysiological and metabolic properties in ISO induced myocardial necrosis in rats.

Rats treated with isoproterenol (ISO, 85 mg/kg, sc, twice at an interval of 24 h) showed a significant increase in heart rate, mean arterial blood pressure, pressure rate index, ST elevation on ECG, and a significant increase in the levels of cardiac marker enzymes- lactate dehydrogenase, and creatine kinase in serum and a significant reduction in superoxide dismutase, and catalase and increase in thiobarbituric acid reactive substance activity in heart tissue. Treatment with Human umbilical cord blood (hUCBC; 500 and 1000 µL, iv, via the tail vein; 2 h after the second dose of ISO) significantly restored back to normal levels and showed a lesser degree of cellular infiltration and infarct size in histopathological and planimetry studies respectively. Thus, hUCBC ameliorates cardiotoxic effects of isoproterenol and may be of value in the treatment of myocardial infarction.
