RESUMO

Tagetes patula is used to treat cancer patients in alternative healthcare systems. However, its cytotoxic and genotoxic effects have not been reported. Therefore, themethanol extract of T. patula flower, the ethyl acetate fraction, and the pure compound patuletin were evaluatedusing the Allium test.The methanol extract and fraction contained ~3% and ~36% patuletin, respectively, with ~98% purity. The methanol extract caused inhibition of Allium root growth displaying an IC50 value of ~500 µg/mL, while the fraction and patuletin were more potent by ~2 and ~5 times, respectively. The Allium root tips demonstrated a decline in prophase, metaphase, anaphase, and telophase stages with concomitant decrease in percent mitotic index in the methanol extract (~5.64), fraction, and patuletin (~4) as compared to the control (~7.61). However, in only methanol extract-treated root tips, an increase in metaphase stage was noted. In addition, the methanol extract predominantly induced c-type, misaligned, and multipolar chromosomal abnormalities while the fraction and patuletin displayed fragments and sticky chromosomes. The fraction and patuletin also produced micronuclei (~2%). In conclusion, T. patula flower methanol extract and ethyl acetate fraction are cytotoxicand genotoxic, which most likely could be due to the patuletin. Further preclinical and clinical studies are required to justify its clinical use.

RESUMO

BACKGROUND: Exclusive breastfeeding is significantly associated with strong infant immunity and optimal development. The importance of breastfeeding is underestimated. Parental lack of knowledge and unhealthy practices regarding breastfeeding deprive infants of their basic right to mother's milk. In developing countries, including Pakistan, with high child mortality and malnutrition, healthy breastfeeding practices can bring positive changes in child health status. From this perspective, the present study aims to understand parents' knowledge, attitudes and practical encounters with breastfeeding practices and the factors that prevent them from adopting such practices. METHODS: A qualitative study was carried out in both rural and urban settings in Rajanpur District of Punjab Province, Pakistan. We conducted 12 focus-group discussions (FGDs) that involved 38 mothers and 40 fathers with children aged under two years who were being breastfed. A thematic content analysis of data collected through FGDs was performed manually. The themes were both inductive and deductive in nature. RESULTS: The study found that a majority of participants believed that the first thing given to an infant after birth should not be breast milk but honey, rose flower, or goat's milk from the hands of an elder in the family or a religious person. No cleanliness measures were practised in this regard. The participants had misconceptions about the benefits of colostrum, which frequently prevented it being given to newborns. Participants reported many factors, such as: insufficient milk syndrome (slow growth of infants due to insufficient daily breast milk intake), a mother's high workload, lack of social support, the influence of culturally designated advisors, and the promotion and marketing strategies of infant formula companies, that undermined exclusive breastfeeding efforts and encouraged mothers to switch to infant formula. CONCLUSIONS: Culturally acceptable and integrated public health interventions are needed to improve the breastfeeding-related health literacy and practices of parents, grandparents and communities. This will ultimately reduce the high infant mortality and malnutrition rates in Pakistan.
