Papillary thyroid carcinoma (PTC) is one of the most common cancers of the endocrine system. Previous studies have shown that the extract of hull-less pumpkin seed (HLPS) has a significant anti-cancer effect. The aim of this study was to evaluate the effect of this plant extract on the proliferation of PTC cells. In this study, an extract of this plant was prepared by soxhlet extraction method and analyzed by Gas Chromatography-Mass Spectrometry. The cytotoxicity of PTX and plant extract was investigated using the methylthiazol tetrazolium (MTT) method. For careful investigation of morphological alteration, we used hematoxylin and eosin and Giemsa stinging. Based on MTT assay test, the IC50 value of paclitaxel (PTX) was significantly less than the hydro-alcoholic extract of HLPS at all of the incubation time. Our results of histological staining showed that HLPS and PTX induced significant morphological alteration in the PTC cultured cell that consistent with cell death. Comparing the groups treated by PTX or HLPS with control group showed significant differences. It seems that HLPS extract has an apparent effect on treatment of PTC, at least in laboratory condition, albeit for realistic decision about the effect of HLPS on PTC, more molecular investigations are necessary.

The aim of medical education is to teach the essence of practical skills alongside with the theoretical knowledge. Teaching anatomy, as the center of medical education, should be leading to use this knowledge as a skill during clinical period. According to the rising numbers of dentistry faculties’ experiences, inappropriate education results in misguidance during clinic. Thus, this study was conducted to find about the pre-clinical and clinical dentistry students’ points of view on the helpfulness of anatomy classes in achieving clinical goals. Present descriptive cross-sectional study evaluated Guilan University of Medical Sciences’ pre-clinical and clinical dentistry students’ opinions on the effectiveness of anatomy classes during their clinical period in 2017. The sampling method used here was census via questionnaire and scoring was according to Likert scaling system. Analyses showed that anatomy of the nervous system was the most assistive course, which helped dentistry students during their clinical period (P<0.001). The least scored course was visceral organs and that means they did not use most of their learnings from classes with this topic (P<0.001). They also stated that other important factors such as using cadavers and moulages in practical sessions, teaching clinical skills theoretically before practical sessions and performing group activities are crucial for them to recall important details of the relevant courses during clinical period. Results of this study suggests that alongside with the various topics of anatomy courses, other factors like professors’ characteristics and their teaching methods are also of important factors helping the dentistry students throughout clinic.
