This study was carried out to investigate the effects of dietary putrescine (PUT) on broiler's response fed low crude protein (CP) diets. A total of 192 male day old chicks were fed with four dietary treatments including two levels of PUT (0 and 0.03%) and two levels of CP (normal and low) with factorial combinations. Weekly growth performance, nutrient digestibility and intestinal morphology (at the age of 21 days) and liver and intestinal tissue polyamines content were measured. As a result of this study lower dietary CP had a significant (P<0.05) lower body weight gain (BWG) and improved protein efficiency ratio (PER). PUT improved energy efficiency ratio (EER) significantly (P<0.05). Dry matter (DM) digestibility was decreased by lower dietary CP whereas 0.03% PUT significantly (P<0.05) increased it. Low CP caused significant (P<0.05) greater calcium digestibility, while this effect was not found when PUT was added. PUT had no effect on intestine villous height and crypt depth. Polyamine content of intestine and liver was influenced by the age of the birds, while PUT had no effects on them. In conclusion, dietary PUT has beneficial effects on EER in chicks fed CP-deficient diet, indicating possible involvement of PUT in energy metabolism. PUT supplementation did not moderate the reduced BWG of the chicks fed low protein. Intestinal and liver polyamine concentration was mainly affected by dietary CP and age of the birds rather than dietary PUT.

INTRODUCTION: This study aimed to evaluate knowledge, attitudes, practice associated with Human Papillomavirus (HPV) Vaccine for Young Children among lecturers and health staffs of Shahid Beheshti University of Medical Sciences (SBMU).
METHOD: This was a cross-sectional study with 220 adults from five different specialties, randomly selected. Data was collected using 45-item questionnaire on knowledge (12- item), attitude (18-item) and practice (15-item) (KAP) about HPV. The demographic questionnaire included information on age, gender, level of education, occupation, and marital status. Content validity was calculated by content validity ratio (CVR) and content validity index (CVI). Reliability was evaluated using test-retest and by Cronbach's Alpha coefficient, internal consistency was calculated values >0.81 which considered as satisfactory.
RESULTS: The mean age of the studied population was 37.70± 8.07 (23-67) years. Of the 220 participants, 80 (36.4%) were males and 140 (63.6%) were females. In evaluating KAP in the men and women, the mean and standard deviation of knowledge were estimated at good level and one-way ANOVA analysis showed significant differences between women and men (p=0.019). There was no significant difference in men and women related to attitude (p=0.92) and practice (p=0.38).
CONCLUSION: The KAP about HPV among participants was significantly higher at good levels compared to average levels. Women's knowledge was significantly higher than men. Attitude and practice could have been higher because there was consensus to the usage of vaccine among the specialists to prevent HPV.
