Prevalence of gastrointestinal parasitic infections in sheep of Subarnachar upazilla in Noakhali district of Bangladesh
(A thesis submitted in the partial fulfillment of the requirements for the degree of Master of Science in Parasitology. Department of Pathology and Parasitology Faculty of Veterinary Medicine Chittagong Veterinary and Animal Sciences University Chittagong-4225, Bangladesh, 2017-12) Hossain, Md. Meraj
Gastrointestinal parasitic infection is a major cause of failures in sheep production in Bangladesh. A study was conducted to determine the prevalence of gastrointestinal parasitic infections of sheep in Subarnachar upazilla of Noakhali district in Bangladesh during January 2017 to December 2017. In total, 200 rectal fecal samples of non-descriptive indigenous sheep were randomly collected and were examined by routine coproscopical methods and modified McMaster technique. The effects of topography, age, sex, rearing system, health status and management system on gastrointestinal parasitic infections were evaluated by chi-square test. The overall prevalence of gastrointestinal parasitic infections in sheep was 79.50%. The highest prevalence of gastrointestinal parasitic infections was found in Char Clark union (83.33%) than the others, although their relationship were statistically insignificant (P>0.05). Species wise prevalence of gastrointestinal parasitic infections was Fasciola sp. (37.5%), Paramphistomam sp. (41.0%), Strongyloides sp. (46.0%), Strongyle-type (39.5%), Trichuris sp. (28.0%) and Moniezia sp. (34.0%). The occurrence of gastrointestinal parasitic infections was more in young (90.0%) than the adult sheep (70.90%). Female sheep displayed a higher infection (85.0%) as compared to male (71.25%) and free range grazing sheep (82.66%) in bathan area was more infected as compared to semi-intensive system (77.66%). Good healthy animals had infection with EPG level of 380-1000 as compared to moderate healthy (>1000-2000) and poor healthy (>2000) animals. The animals those were reared under proper management system including regular deworemed by anthelmentics, proper housing and feeding with nutritional supplement were less infected by gastrointestinal parasites. As the present study was fresh of its type in the study areas, further investigation is recommended to evaluate the region specific risk factors.
Unlocking the Potential of Henna Leaves
(Daffodil International University, 23-07-22) Hossain, Md. Meraj
Henna leaves (Lawsonia inermis) have long been recognized for their potential hair growth properties and have been utilized in traditional practices. This review article aims to comprehensively examine the role of henna leaves in promoting hair growth and provide insights into their efficacy, safety considerations, and optimal application methods. The study begins with an exploration of the phytochemical composition of henna leaves, highlighting the presence of bioactive compounds such as lawsone, tannins, flavonoids, essential oils, and phenolic compounds. These compounds contribute to the potential hair growth benefits of henna leaves. The mechanisms of action underlying the hair growth effects of henna leaves are discussed, including their anti-inflammatory properties, antioxidant activity, stimulation of hair follicle activity, regulation of the scalp microbiome, and nourishing effects on the hair and scalp. These mechanisms create a favorable environment for hair growth and help mitigate hair loss conditions. Clinical studies investigating the efficacy of henna leaves for hair growth are summarized. Findings from randomized, placebo-controlled trials reveal positive outcomes, with improvements in hair density, hair diameter, and the ratio of anagen to telogen hair follicles observed in participants receiving henna extract or henna-based formulations. Safety considerations and potential side effects associated with the use of henna leaves are discussed. While henna leaves are generally considered safe, precautions such as patch testing and ensuring the quality and purity of henna products are emphasized. The review also delves into the application methods of henna leaves for hair growth, providing insights into various techniques and their effectiveness. Additionally, synergistic combinations with other natural ingredients for enhanced hair growth are explored. In conclusion, henna leaves hold promises as a natural remedy for promoting hair growth. The findings highlight the potential of henna leaves in addressing hair loss conditions through their diverse mechanisms of action. However, further research is needed, including large-scale clinical trials, mechanistic investigations, and long-term safety assessments, to establish their efficacy and optimize their use. By considering the phytochemical composition, mechanisms of action, clinical studies, application methods, and safety considerations, individuals can make informed decisions when using henna leaves to promote hair growth.
