AbstrakDiabetes mellitus merupakan masalah utama kesehatan di dunia dan prevalensinya selalu meningkat. Pada dosis yang tepat kandungan nikotin dari ekstrak etanol daun tembakau (Nicotiana tabacum) memiliki efek hipoglikemik sehingga berpeluang sebagai terapi alternatif untuk diabetes mellitus. Namun, efeknya pada jaringan adipose penderita diabetes mellitus belum banyak diketahui. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh ekstrak etanol daun tembakau terhadap berat lemak visceral tikus model diabetes mellitus. Pada penelitian ini tikus galur Wistar dibagi menjadi 5 kelompok yaitu kontrol negatif (K-), kelompok tikus model diabetes mellitus (K+), dan tiga kelompok tikus diabetes melitus yang diberi ekstrak etanol daun tembakau 90 (P1), 180 (P2) dan 270 (P3) mg/kgBB/hari per oral selama 28 hari. Hasil penelitian menunjukkan bahwa terdapat penurunan bermakna berat lemak pada semua kelompok tikus DM yang diberi ekstrak daun tembakau dibandingkan dengan tikus DM tanpa terapi maupun tikus normal (p < 0,05). Kesimpulan penelitian adalah pemberian ekstrak etanol daun tembakau menurunkan berat lemak visceral pada tikus model DM. Penurunan berat lemak visceral kemungkinan disebabkan oleh kandungan nikotin dalam ekstrak yang dapat mengaktivasi lipolisis, menghambat lipogenesis, aktivasi thermogenesis, dan penurunan intake makan.Kata kunci: berat lemak visceral, diabetes mellitus, daun tembakau (Nicotiana tabacum). ETHANOL EXTRACT OF Nicotiana tabacum REDUCES THE VISCERAL WEIGHT OF TYPE TWO DIABETIC RATS AbstractDiabetes melllitusis the main health problem in the world and its prevalence is increasing dramatically. Tobacco leaf (Nicotiana tabacum) containing nicotine could be used as an alternative treatment for diabetes mellitus at the right dose. However, its effect on adipose tissue of diabetes mellitus model has not established well. This study aim is to observe the effect of ethanol extract of tobacco leaf to the visceral weight of diabetic rats. Rats were divided into five group normal rats (K-), diabetic rats (K+) and diabetic rats receiving ethanol extract of tobacco leaf at dose 90 (P1), 80 (P2), and 270 (P3) mg/kgBW/day orally for 28 days. Rats were sacrificed and visceral fat was weighed afterward. As the result, visceral fat of diabetic rats was less than the normal rats and diabetic rats treated with ethanol extract of tobacco leaf shown to reduce visceral weight significantly compared to normal rats (p < 0.05). Visceral weight decrement was due to nicotine effect that could induce lipolysis, inhibit lipogenesis, thermogenesis activation, and reduce food intake. Further research is needed to explore Nicotiana tabacum as an alternative treatment for diabetes mellitus.
Reverse nearest neighbors query as an indispensable part of spatial retrieve plays an important role in spatial analysis and spatial processing. In this paper, we target the problem of reverse nearest neighbors query for moving objects. We devised a spatio-temporal index suitable for this problem firstly and then an algorithm for reverse nearest neighbors search is proposed based on this index. The results of experimental evaluation demonstrate that this algorithm outperforms others for reverse nearest neighbors queries of moving objects. This work can better improve and enhance the power of quantitative analysis and process for spatio-temporal database.
Background: Based on previous studies, vitamin D deficiency could lead to nerve stimulation. The purpose of the present study was to determine frequency and duration of seizures in children with idiopathic epilepsy in two groups; normal level of vitamin D versus decreased level of vitamin D. Methods: This pilot, comparative study was carried out in Zanjan University of Medical Sciences on total 40 children aging between 2 to 12 years old (23 male and 17 female) with the diagnosis of idiopathic epilepsy. All patients were receiving anti-epileptic drugs. The initial questionnaire was completed by each parent. Total 40 epileptic cases were examined in close follow-ups every three months, during total 9 months. Meanwhile, the frequency and duration of each seizure were recorded in questionnaire at every three-month period. Vitamin D blood samples were analyzed at the beginning of the study and after 9 months following the study. Serum levels of Vitamin D were analyzed by ELISA method (Elecsys2010, RocheCo, Germany; STAR FAX; 2100), simultaneously, Vitamin D level <30 ng/ml (nanogram per milliliter) was defined as Vitamin D deficiency. Cases were divided into two groups based on Vitamin D level. The frequency and duration of convulsions were compared in patients with normal level of vitamin D versus children with decreased level of vitamin D. Data were analyzed by Chi-square and t-test methods. Results: In all 40 patients, vitamin D level less than 30 ng/ml was detected in 32% (13 patients) at the beginning of study and 35% (14 patients) in 9 months later (13 patients were common between the two groups). There was no significant relationship between the frequency of seizures, the duration of seizures and vitamin D levels in patients. The relationship between positive family history of epilepsy and the number of seizures was reported significant. The frequency of vitamin D deficiency was higher in female cases in final evaluation. Conclusion: In the present study, a considerable correlation was detected between the frequency of seizures and positive history of seizure in the family. The frequency of vitamin D deficiency was higher in female cases in final analysis. No significant relationship was detected between the number of seizures, the mean duration of seizures and serum level of Vitamin D in children who received anticonvulsant drugs. However, vitamin D deficiency in patients was not overlooked in order to prevent known complications. We recommend a randomized clinical trial in the future with an adequate sample size. Moreover, a non-epileptic control group in study would be useful.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
