Abstract
Introduction: Treatment in chronic constipation is highly dependent on colon transit time (CTT), which not only determines the cause but also determines the correct treatment policy. The aim of this study was evaluation of CTT in constipated patients.
Methods: 43 patients with chronic constipation who did not respond to high fiber diet were enrolled in the study. Patients with history of drug induced constipation, Parkinson disease, multiple sclerosis, cerebrovascular accident, hypothyroidism, diabetic mellitus, opium addiction or previous abdominal surgery were excluded from the study. The subjects were administered 30 radio opaque markers orally (capsule form) in the morning and X.Ray was done 120 hours later. In normal patients we expect only 20% of markers (6 markers) to be retained in the colon lumen after 120 hours. Patients with more than 6 markers in colon lumen after 120 hourswere defined as abnormal CTT and were classified as colon inertia or abnormal defecation according to the position of the retained markers in the colon lumen.
Results: 40 patients completed the study. 16 patients were male and 24 were female. 22(55%) patients had normal CTT. 7 patients (17.5%) had colon inertia and 3 (7.5%) had abnormal defecation, while 8 patients (20%) had both of them. No significant difference was observed between males and females.
Conclusion: The pattern of CTT in constipated patients can be determined cost effectively.

Abstract
Introduction: Access to modern methods for increasing the percentage of in vitro human and animal mature oocytes can be useful in the treatment of some forms of human infertility as well as proliferation of many domestic and wild animals which generation is endangered. Effect of low- frequency electromagnetic fields on in vitro growth and maturation of mouse oocytes is recently considered as a new approach. In this study we evaluated the effect of low- frequency electromagnetic field on in vitro growth and maturation of mouse oocyte.
Methods: In this study electromagnetic fields with frequencies of 5, 50 and 100 Hz and 2mT intensity were used. For observation of the effect of electromagnetic field four groups were selected: Group 1 as control group, which included 35 prenatal follicles (immature oocytes). Groups 2, 3 and 4were exposed to 5, 50 and 100 Hz electromagnetic fields, respectively.
Results: Prenatal follicles exposed to 5 and 50 Hz frequencies showed no significant changes in diameter and survival rates. In contrast at a frequency of 100 Hz in 72-hour culture period a significant increase in diameter(155μm), follicles livability power(59%), oocyte maturation(52%) and GVBD(39%) was shown in comparison to other experimental groups and control group(P <0.05).
Conclusion: Low-frequency magnetic field effects gene expression and thus protein synthesis, cell division, proliferation and behavior. Although this effect can be temporary, it can increase the percentage of ovulation for in vitro environment along with other environmental factors.
