Simple Obesity

Aim. The study is aimed at investigating the curative effect of acupuncture on simple obesity and its influence on serum levels of prostaglandin E and leptin in Sprague-Dawley (SD) rats. Methods. In the study, there are 50 male SD rats. We took 10 as healthy controls and fed 40 with a diet of high fat for 8 weeks. After the 40 rat model was established successfully, we fed 10 rats in the model group with a normal diet and treated 10 rats in the acupuncture group by acupuncture. During the experiment, the body fat and body length of rats were measured weekly, and Lee’s index was calculated. After the treatment, the levels of leptin, prostaglandin E, C-reactive protein (CRP), triacylglycerol (TG), cholesterol (CHO), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) were detected, and the liver fat morphology was observed by electron microscope. Results. Acupuncture significantly downregulated the serum levels of CRP, TG, CHO, LDL, leptin, and prostaglandin E and upregulated the serum levels of HDL in rats with simple obesity. Conclusion. On basis of these results, it was found that acupuncture could boost fat metabolism and weight loss by inhibiting the production of leptin and prostaglandin E.

Glomerular Hypertension

The Nagase analbuminemic rat (NAR), a mutant of the Sprague-Dawley (SD) strain, exhibits high levels of plasma cholesterol (Chol), thrombocytosis, and enhanced platelet aggregability, which might promote glomerulosclerosis (GS). To determine whether NAR are more susceptible than SD rats to aging GS, young (3-mo-old) and aging (18-mo-old) SD rats and NAR were studied. In young NAR, glomerular pressure and glomerular volume were lower, whereas total and high-density lipoprotein plasma Chol levels were higher than in young SD rats. Aging SD rats developed glomerular hypertension and hypertrophy. Less glomerular enlargement and subnormal glomerular pressures were seen in aging NAR. Enhanced platelet aggregation developed in aging SD rats, approaching the values seen in NAR. Similarly elevated levels of low-density lipoprotein Chol were seen in additional SD rats and NAR studied at 12 mo of age. Plasma triglyceride (TG) levels were lower in NAR at this age. Only SD rats developed proteinuria and exhibited GS and glomerular lipid deposits at 18 mo of age. Reduced glomerular wall stress due to lower glomerular pressure and volume as well as lower TG levels may explain the absence of GS in aging NAR despite plasma lipid and platelet abnormalities.

Schisandrae Fructus (SF), the fruit of Schisandra chinensis (Turcz.) Baillon, has been used for the treatment of liver injury and metabolism-related disorders in China. The objective of this study was to investigate the effects of supplementation with ethanol extract of SF seed (EtSF-S) on serum/hepatic lipid and glucose levels as well as fecal total cholesterol (TC) contents in mice fed a normal diet (ND) or high-fat/fructose diet (HFFD) containing 15% lard oil and 15% fructose. Female ICR mice (18–20 g in body weight) were fed with ND or HFFD for 3 months, and then EtSF-S was added to both chow diets at increasing concentrations of 1, 5, and 10% (w/w). Thirty days later, serum and hepatic lipids, including TC, triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and glucose, were measured. Dietary supplementation with EtSF-S reduced hepatic TC (36 and 18%) and TG levels (38 and 28%) and increased serum HDL/LDL ratio (16 and 26%) in both ND- and HFFD-fed mice, respectively. Moreover, supplementation with EtSF-S elevated serum HDL (31%) in HFFD-fed mice and reduced serum LDL (27%) in ND-fed mice. EtSF-S treatment reduced fat mass (40%) in ND-fed mice and increased fecal TC contents (33%) in HFFD-fed mice. EtSF-S supplementation decreased hepatic glucose contents (29%) in both ND- and HFFD-fed mice. However, diet supplemented with EtSF-S elevated serum TG levels (up to 123%) and hepatic size (28%), but more importantly, suppressed the body weight gain (approximately 130%) in mice fed with HFFD. These findings suggested that dietary supplementation with EtSF-S as natural herbal function food may be a useful strategy for the treatment of patients with fatty liver disease or overweight without a high intake of sugar and fat.

The antiobesity effects ofCodonopsis lanceolata(CL) were evaluated in a high-calorie/high-fat-diet (HFD-) induced obesity rat model and 3T3-L1 cells. The Sprague-Dawley male rats were fed a normal diet (ND) or a HFD for a period of 12 weeks. The rats were subdivided into groups: ND, ND + wildCodonopsis lanceolata(wCL) (900 mg/kg/day, p.o.), ND + cultivatedCodonopsis lanceolata(cCL) (900 mg/kg/day, p.o.), HFD, HFD + wCL (100, 300, or 900 mg/kg/day, p.o.), HFD + cCL (100, 300, or 900 mg/kg/day, p.o.), and HFD + sibutramine. The body weight gains of the administered HFD + CL (wCL or CCL) were lower than those of the rats fed with only the HFD group. Moreover, the weight of adipose pads and the serum levels of triglycerides, total cholesterol, and low density lipoprotein cholesterol in the group administered HDL + CL were significantly lower than in the HFD group. The inhibitory effect of lipid accumulation in 3T3-L1 cells was measured by Oil Red O staining and reverse transcription-polymerase chain reaction (RT-PCR). Treatment of 3T3-L1 cells with wCL inhibited lipid accumulation and expression of C/EBPαand PPARγ. These results suggest that CL has a great potential as a functional food with anti-obesity effects and as a therapeutic alternative in the treatment of obesity.

Beneficial Effects

Scientific endeavor has made it possible to discover and synthesize lipid-lowering drugs but, in most cases, their beneficial effects are overshadowed by their adverse effects. Hence, research interest in the screening of medicinal plants has intensified in recent years with a view of discovering potential antioxidants, lipid, and glucose-lowering phytochemicals. Four-month feeding of carbamazepine (both 5 mg/kg and 20 mg/kg body weight) with a normal diet increased the body mass of rats. Low-density lipoprotein (LDL) cholesterol level was increased based on the oral execution of carbamazepine. But high-density lipoprotein (HDL) cholesterol level and weight of the liver increased slightly and the level of triacylglycerol (TG) and total cholesterol (TC) level remain unchanged. Nonetheless, the Begonia barbata feeding with a normal diet reduced carbamazepine-induced obesity at both high and low doses. The level of LDL cholesterol and liver weight was significantly decreased due to the oral execution of B. barbata together with normal diet and carbamazepine, where HDL level was changed but not significantly.

Cardioprotective Effects

Our aim was to investigate whether trans-resveratrol (t-resveratrol), a red wine constituent known for its cardioprotective effects, was able to influence CD40 ligand (CD40L) and its receptor CD40 in platelets of hypercholesterolemic rats. Sixty Wistar rats were divided into 5 groups: control (C), ethanol (E), t-resveratrol (R), hypercholesterolemia (HC), and hypercholesterolemia plus t-resveratrol (HCR). Rats in the C, E, and R groups were fed a normal diet for 80 days. For 20 days before sacrifice, we intraperitoneally (i.p.) administered 0.1 mL ethanol (50% v/v) to the E group, and 0.1 mL t-resveratrol (20 mg·kg–1·day–1) to the R group. Rats in the HC and HCR groups were fed a 5% cholesterol diet for 80 days. Rats in the HCR group were administered i.p. 0.1 mL t-resveratrol (20 mg·kg–1·day–1) for 20 days before sacrifice. Serum levels of total cholesterol (TC), low-density lipoprotein (LDL-C), high-density lipoprotein (HDL-C), very low-density lipoprotein (VLDL-C), and total triglycerides (TG) were assayed with a commercial colorimetric kit. Platelet P-selectin, CD40, and CD40L expression was determined by flow cytometry. sCD40L and IL6 levels were measured by ELISA. In the HC group, we observed a significant increase in serum TC, LDL-C, VLDL-C, TG, sCD40, and IL-6 levels and platelet activation markers compared with levels in the control group. However, t-resveratrol administration to the HC group (HCR group) attenuated the increase in lipids, sCD40, and IL-6 and down-regulated platelet P-selectin, CD40, and CD40L expressions. A positive correlation was found for serum lipids and all the platelet activation markers. Our study showed that the CD40–CD40L dyad is up-regulated in the presence of hypercholesterolemia and that t-resveratrol administration down-regulated the increase.

Relevance. There are numerous publications of foreign authors about relationship between Pyloric Helicobacter (H. p.) infection with several gastroduodenal diseases, including metabolic disorders. Russia is one of the countries with high prevalence of H. p. infection and metabolic disorders. Determining their relationship is important for both prevention and treatment of metabolic disorders. Purpose - study the possibility of relationship between H. p. infection and type 2 diabetes, dyslipidemia, overweight and obesity. Methods and materials. The study included 1487 working residents of Moscow and the Moscow region, 931 men and 556 women, aged 21 to 77 years (median - 46). H. p. infection was diagnosed by detecting antibodies to IgG bacteria in the blood serum. In 698 infected individuals, the presence of a CagA strain, a marker of virulence of the bacterium, was studied using ELISA. Serum levels of basal glucose, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides were studied, and the body mass index was determined. Results. Infection was discovered in 1348 people (90.6%), CagA positive - 392 (56.2%). Type 2 diabetes was diagnosed in 77 people, 74 - H. p. positive (5.5% ), and 3 - H. p. negative (2.1%). CagA was studied for 31 persons with diabetes. CagA-positive bacterial strain was determined in 22 cases out of 31 (70.1%, p 0,05, by criterion χ²). Among H. p. positive, overweight was registered in 884 cases (65.6%), in H. p. negative - in 74 cases (53.2%) (p

Цель - исследование взаимосвязи факторов риска сердечно-сосудистых заболеваний и развития предгипертонии. Методика. Проведен сравнительный и корреляционный анализы показателей модифицируемых и немодифицируемых факторов риска сердечно-сосудистых заболеваний у обследованных лиц в возрасте 30-60 лет с «оптимальным» артериальным давлением, (n = 63, АД <120/80 мм рт.ст.) и лиц с предгипертонией (n = 52, АД = 120-139/80-89 мм рт.ст.). Результаты. Показано, что лица с предгипертонией по сравнению с группой лиц, имеющих «оптимальное» артериальное давление характеризуются статистически значимо повышенным содержанием холестерина и холестерина липопротеидов низкой плотности, интеллектуальным характером трудовой деятельности, а также значимыми сочетаниями факторов риска: повышенный уровень холестерина липопротеидов низкой плотности с интеллектуальным характером трудовой деятельности; повышенное содержание креатинина с уровнем триглициридов; наследственная отягощенность по заболеваниям почек и интеллектуальным характером трудовой деятельности; наследственная отягощенность по сахарному диабету и гипертрофия левого желудочка сердца. У лиц с предгипертонией документированы перестройки структуры взаимосвязи (количество, направленность и сила корреляций) между показателями факторов риска в сравнении с лицами, имеющими «оптимальное» артериальное давление. Заключение. Выявленные особенности взаимосвязей факторов риска сердечно-сосудистых заболеваний при предгипертонии рассматриваются как проявление начальной стадии дизрегуляционной патологии и нарушения регуляции физиологических систем поддержания оптимального уровня артериального давления. The aim of the study was to investigate the relationship between risk factors for cardiovascular disease and development of prehypertension. Methods. Comparative and correlation analyses of modifiable and non-modifiable risk factors for cardiovascular disease were performed in subjects aged 30-60 with «optimal» blood pressure (n = 63, BP <120/80 mm Hg) and prehypertension (n = 52, BP = 120-139 / 80-89 mm Hg). Results. The group with prehypertension compared with the «optimal» blood pressure group had significantly increased serum levels of low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol, sedentary/intellectual type of occupation, and significant combinations of risk factors. The risk factor combinations included an increased level of LDL cholesterol and a sedentary/intellectual occupation; increased serum levels of creatinine and triglycerides; hereditary burden of kidney disease and a sedentary/intellectual occupation; hereditary burden of diabetes mellitus and cardiac left ventricular hypotrophy. In subjects with prehypertension compared to subjects with «optimal» blood pressure, changes in correlations (correlation number, direction, and strength) between parameters of risk factors were documented. Conclusion. The features of interrelationships between risk factors for cardiovascular disease observed in prehypertension are considered a manifestation of early dysregulation pathology and disordered regulation of physiological systems, which maintain optimal blood pressure.

Background. Dyslipidemia contribute to the excess of coronary heart disease (CHD) risk observed in women with type 2 diabetes (T2DM). Low density lipoprotein-cholesterol (LDL-C) is the major target for CHD prevention, and T2DM women seem to reach LDL-C targets less frequently than men.Aim. To explore age- and gender-related differences in LDL-C management in a large sample of outpatients with T2DM.Results. Overall, 415.294 patients (45.3% women) from 236 diabetes centers in Italy were included. Women were older and more obese, with longer diabetes duration, higher total-cholesterol, LDL-C, and HDL-C serum levels compared to men (P<0.0001). Lipid profile was monitored in ~75% of subjects, women being monitored less frequently than men, irrespective of age. More women did not reach the LDL-C target as compared to men, particularly in the subgroup treated with lipid-lowering medications. The between-genders gap in reaching LDL-C targets increased with age and diabetes duration, favouring men in all groups.Conclusions. LDL-C management is worst in women with T2DM, who are monitored and reach targets less frequently than T2DM men. Similarly to men, they do not receive medications despite high LDL-C. These gender discrepancies increase with age and diabetes duration, exposing older women to higher CHD risk.
