| 5 | Paraoxonase-1 gene in patients with chronic obstructive pulmonary disease investigation Q192R and L55M polymorphisms显示文摘BACKGROUND: The effect of increased oxidative stress on the development of chronic obstructive pulmonary disease(COPD) is well known. One of the antioxidative systems against oxidative stress in human body is paraoxonase(PON) enzyme that protects low density lipoproteins(LDL) against oxidation. This study aimed to explore the polymorphisms on PON1, Q192 R, L55 M genes of patients with COPD.METHODS: DNAs extraction was obtained from blood samples of 50 patients diagnosed with COPD and 50 patients as a control group who were presented to emergency clinic. Genotypes were obtained with polymerase chain reaction(PCR) and AIw I and Hsp92 II restriction enzymes were used for Q192 R and L55 M polymorphisms, respectively. Analysis of data was done with the Chi-square test and Fisher's exact test.RESULTS: A statistically significant difference in Q192 R polymorphism was found between the COPD patients and the control group(P=0.05). There was no statistically significant difference in L55 M polymorphisms between the patient and control groups(P>0.05). Q192 R polymorphism was significantly correlated with the PON1 gene and cigarette smoking; however other risk factors did not show any significant correlation with this polymorphism. Though L55 M polymorphism was significantly correlated with family history and tuberculosis, there was no significant correlation with other risk factors.CONCLUSION: We believe that more studies are needed to study the correlation of L55 M polymorphism with other factors. | ?ükrü Gürbüz Mustafa Y?ld?z Murat Kara Kür?at Kargün Mehtap Gürger Metin Ate??elik ?mer Do?an Alata? | 2015 | World Journal of Emergency Medicine2015，6，3： | 1 |
| 9 | Demographic features and histopathological diagnosis in primary eyelid tumors: results over 19 years from a tertiary center in Ankara, Turkey显示文摘AIM:To evaluate the demographic features,location,and histopathologic results in primary eyelid tumors.METHODS:We retrospectively reviewed the records of patients with primary eyelid tumor diagnosed and treated between November 1997 and June 2016 on our service.RESULTS:Nine hundred and eleven lesions from 874 patients were included in this study.Four hundred and fortysix(51.0%)of the patients were females and 428(49.0%)were males.The mean age was 51.0y(range:3 mo-94 y).The lesions were located in the upper eyelid(418 cases,45.9%),lower eyelid(378 cases,41.5%),medial canthus(89 cases,9.8%),and lateral canthus(26 cases,2.8%).Four hundred and seventy(51.6%)lesions were located on the right side and 441(48.4%)on the left.Of the eyelid lesions,666(73.1%)were benign,230(25.2%)malignant,and 15(1.6%)premalignant.When the eyelid tumors were classified according to their tissue or cell of origin,527(57.8%)of the lesions were found to be epidermal,171(18.8%)adnexal,131(14.4%)inflammatory and infectious,and 65(7.1%)stromal.The most common benign lesions were squamous cell papilloma(139 lesions,15.2%),intradermal nevus(97 lesions,10.6%),epidermoid inclusion cysts(78 lesions,8.6%),seborrheic keratosis(60 lesions,6.6%),and inflammatory masses(59 lesions,6.5%).Basal cell carcinoma was the most common malignant tumor(191 lesions,21.0%)followed by squamous cell carcinoma(16 lesions,1.8%),sebaceous carcinoma(14 lesions,1.5%),and malignant melanoma(5 lesions,0.5%).CONCLUSION:In this study,73.1%of eyelid lesions are benign and the remaining 26.9%are premalignant and malignant.Basal cell carcinoma is the most common tumor among all histopathological diagnosis followed by squamous papilloma. | Mehtap Arslantürk Eren Ahmet Kaan Gündüz | 2020 | International Journal of Ophthalmology(English edition)2020，13，8： | 0 |
