تأثیر روزه ماه مبارک رمضان بر پاسخ ازدیاد حساسیت تأخیری نسبت به PPD

Studies during recent decade indicate that low calorie intake has&nbsp;potentiating effect on immune response . So the effect of fasting in holly&nbsp;month of Ramadan on cellular immune was studied. In this study , delayed&nbsp;type hypersensitivity (DTH) to purified protein derivative (PPD) test was&nbsp;selected to evaluate cellular immune response , because this test is not only&nbsp;very simple but also is valuable and reliable. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; This research studied DTH to PPD in two groups of students before&nbsp;and after the holly fasting month of Ramadan. The range of age in the both&nbsp;groups was 20-30 year. Mantoux method was the selected method to&nbsp;evaluate DTH response to PPD. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; DTH response to PPD in fasting group increased from 8.8 to 13 mm ,&nbsp;which is statistically significant (P<0.05). It is noticeable that the differences&nbsp;between the rates of increasing DTH response to PPD in control group and&nbsp;fasting group was statistically significant (P<0.05). &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Based on the above finding it can be concluded that fasting has&nbsp;potentiating effect on cellular immune response.
