Review Study

The aim of the study to estimate the antioxidant action and protecting effect of ethanolic cinnamon extract against CCl4 induced toxicity in male rats. To determine the effect of different concentrations of ethanolic cinnamon extract on male rats that fed a high cholesterol diet that induced hyperlipidemia. The experiment has been conducted in the present study., aimed to evaluate the hepatoprotective, role of Cinnamomum zeylanicum ethanolic extract in carbon tetrachloride (CCl4) induced hepatotoxic male rats, The cinnamon and its oil reported to have many beneficial uses in food preservation due to antioxidant of cinnamon. The Phenolic compounds extracted from cinnamon such as hydroxyl cinnamaldehyde and the hydroxycinnamic acid act as scavengers of peroxide radicals and avoid oxidative damage (Mathew and Abraham, 2006; Leela, 2008). Ranjbar et al, (2006) observed individuals consuming cinnamon tea showed increased total serum antioxidant status, increased thiols such as glutathione, NADPH, NADH, SOD, and decreased lipid peroxidation.

The rind of rambutan fruit (Nephelium lappaceum L.) has been reported to have a very strong antioxidant activity with IC50 value of 7.74 μg / mL. The fruit contains  avonoids and phenolic . This compounds are potentially as hypolipidemic effect. This study aims to determine the hypolipidemic effect of 96% of ethanolic extract of rind of rambutan fruit in wistar strain male rats. This research method is the pre- and post-control group design. 25 rats were divided into 5 groups. Group I (negative control) were treated by a solution of 0.5% CMC-Na, group II (positive control) were treatedby cholestyramine 0.8 kg / kg, whereas group III, IV and V treated by 96% of ethanolic extract of rind of rambutan with a dose of 125 , 250, and 500 mg / kg respectively. hiperkolesterlemia induction is done by giving a high cholesterol diet and feed for 4 weeks. High-cholesterol diet consists of cooking oil, quail egg yolk, water, PTU and feed high cholesterol consisting of margarine and standard feed. Treatment of mice was conducted for 2 weeks. The results showed that the 96% of ethanolic extract of rind of rambutan fruit with a dose of 125, 250, and 500 mg / kgbw have antihyperkolesterol activity 21.39 ± 6.61%, 31.15 ± 18.15%, and 60.75 ± 8, 26%.Keywords: Antihypercholestrol, Nephelium Lappaceum L., High-cholesterol diet

Цель - оценить роль холемии в генезе миокардиальной дисфункции после субтотальной резекции печени у крыс. Методика. Эксперименты выполнены на 48 беспородных белых крысах-самцах. 38 животным проводили субтотальную атипичную резекцию 80% печени оригинальным способом, 10 интактных животных составили контрольную группу. Определение общей концентрации желчных кислот в сыворотке крови проводили энзиматическим колориметрическим методом у интактных животных и в 1-е, 3-и и 7-е сут после резекции печени. Прямую оценку сократительной функции и метаболизма миокарда интактных животных проводили на спонтанно сокращающихся изолированных сердцах. При перфузии сердец с добавлением в перфузат желчи, рассчитывали комплекс силовых и скоростных показателей сократимости, определяли содержание глюкозы, лактата, активность аспартатаминотрасферазы в коронарном протоке. Результаты. Выявлено повышение общего содержания желчных кислот в сыворотке крови оперированных животных. Добавление желчи в раствор для перфузии изолированных сердец вызывало развитие брадикардии, снижение силовых и скоростных показателей сократительной функции. При этом происходило увеличение потребления глюкозы, выделения лактата и аспартатаминотрансферазы в коронарный перфузат. Заключение. Полученные данные свидетельствуют о значимой роли холемии, развивающейся после субтотальной резекции печени, в генезе функционально-метаболических нарушений в миокарде. Aim. To assess the role of cholemia in development of myocardial dysfunction following the subtotal hepatic resection in rats. Methodology. Experiments were conducted on 48 white mongrel male rats. Subtotal atypical 80% liver resection was performed on 38 animals using an original method; the control group consisted of 10 intact animals. Total serum concentration of bile acids was measured using the enzymatic colorimetric method in intact animals and on days 1, 3, and 7 after the liver resection. Myocardial contractile function and metabolism were directly evaluated on spontaneously contracting isolated hearts of intact animals. During the heart perfusion with added bile, a set of contractile force and velocity indices was calculated; glucose and lactate concentrations and aspartate aminotransferase activity were measured in the coronary perfusate. Results. The total serum content of bile acids was increased in operated animals at all study points. When bile was added to the perfusion solution, the isolated hearts developed bradycardia, decreases in force and speed indices of the contractile function, increased glucose consumption, and release of lactate and aspartate aminotransferase into the coronary perfusate. Conclusion. The study showed the importance of cholemia following the subtotal liver resection for the development of functional and metabolic disorders of the myocardium.

AbstractThe present study investigated the anti-atherosclerotic potential of myricitrin in hypercholesterolemic rats. Rats were divided into the following groups: sham (standard food), control [1% high-cholesterol diet (HCD)], 1 μM myricitrin + 1% HCD, 10 μM myricitrin + 1% HCD, 100 μM myricitrin + 1% HCD, and the positive control (10 mg/kg body weight atorvastatin). The dose was given to rats via oral gavage for 45 consecutive days. Feeding of rats with 1% HCD caused substantial increases in the levels of LDL, cholesterol, and triglycerides (TG), while high-density lipoprotein (HDL) was reduced. However, rats supplemented with myricitrin had reduced levels of cholesterol, LDL, and TG to near-normal levels, whereas HDL was increased. Catalase, superoxide dismutase (SOD), glutathione peroxidase (Gpx), and reduced glutathione (GSH) levels were substantially reduced in the HCD-fed rats compared with sham rats. However, the rats supplemented with 100 μM myricitrin showed > 50% increases in these levels. Lipid peroxidation and reactive oxygen species (ROS) levels were reduced following myricitrin treatment. The aortic cell wall area was significantly increased by 14.5% in HCD-fed rats. However, rats supplemented with 1, 10, and 100 μM myricitrin showed significant reductions in the aortic cell wall area of 2.3%, 4%, and 27.5%, respectively. This is the first report of the anti-atherosclerotic and hypolipidemic effects of myricitrin in hypercholesterolemic rats. Myricitrin decreased the level of total serum cholesterol and the role of aortic atherosclerosis in hypercholesterolemic rats.
