ABSTRACT
Primarily sourced from Asteraceae family herbs such as the Dandelion, Taraxasterol is a pentacyclic triterpenoid lauded for its extensive biological functionalities. Its therapeutic potency is demonstrated in various disease models, encompassing enteritis, arthritis, acute hepatic injury, and pneumonia. Scientific literature underscores its anti-inflammatory, antioxidant, and antineoplastic attributes. The primary aim of this study is to thoroughly explore the diseasemodulating mechanisms and effects of taraxasterol. We endeavor to provide an exhaustive review of the experimental subjects, intervention components, distinct action modalities, contributing factors, and protein pathway expressions associated with taraxasterol, systematically represented via diagrams and tables. Such a schematic representation encourages a continued academic dialogue concerning taraxasterol's pharmacological characteristics. This review is envisioned as a practical guide for the selection of experimental subjects and methodologies in prospective research. It is intended to further illuminate taraxasterol's pharmacodynamics, thereby offering theoretical and empirical justification for its clinical application.
ABSTRACT
Third molar impaction is considered a prevalent issue. The research aimed to study the pervasiveness and pattern of impaction in Karbala/Iraqi population. Orthopantomograms were studied regarding its angulation, impaction depth, and correlation with ramus. The outcomes manifested that the prevalence of 3rd impacted molars was 34.71%, with the proportion of male to female as 0.83:1. Impacted mandibular 3rd molars were significantly encountered. The prevalence of vertical angulation, mesioangular, horizontal, and inverted were significantly associated with the impacted mandibular 3rd molars (P < 0.05). However, the prevalence of distoangular and bucco/lingual was significantly associated (P < 0.05) with the upper impacted 3rd molars. Level C of impaction was significantly (P < 0.05) the most typical level in the maxilla impacted the 3rd molar, and level A and level B of impaction were significantly (P < 0.05) the most prevalent level correlated with the mandibular 3rd molar impaction. Class II was significantly (P < 0.05) the frequently occurring condition subsequent to Classes III and I. In conclusion, the impaction of 3rd molars was significantly predominant in females and lower jaw. The vertical angulation, level C of impaction associated with maxillary 3rd molars and levels A and B of impaction related with mandibular 3rd molars, and Class II are the most encountered conditions.
ABSTRACT
OBJECTIVE: Green tea (GT) contains polyphenolic flavonoids, different minerals like magnesium, calcium, and zinc, vitamins, amino acids, carbohydrates, proteins, and others. It has a different health benefit. The aim of the present study was to investigate the effect of intragastric gavage of a high dose GT extract on serum biochemical analysis of magnesium, calcium, and zincin juvenile Wistar albino rats. METHODS: Twelve rats were used in the study and divided in to two equal groups. All the animals in the control group were intragastically gavaged by distilled water and continues for ten days, from day 24 to day 34 of age, while the animals in the study group were intragastically gavaged by GT extract (300mg/kg/day) which continues also for ten days from day 24 to day 34 of age. On day 34 of age, and two hours after the last dose, the rats were anaesthetized and blood collection by cardiac puncture was taken. RESULTS: The results showed that the intragastric gavage of a high dose of GT extract caused a non-significant increase in serum magnesium, and calcium levels (p>0.05), but a significant increase in zinc serum level was seen(p< 0.05). CONCLUSION: GT can cause a significant increase in zinc serum level, and this may explain the significant role of GT in the response to different oxidative stress. It is recommended to measure the Zn serum level in rats after a period longer than two hrs from the time of the last dose of intragastric gavage of GT extract.
