[Study of-629C/A polymorphism of cholesteryl ester transfer protein gene in statin effects on plasma high density lipoprotein cholesterol level]

Cholesteryl ester transfer protein [CETP] plays pivotal role in HDL metabolism and in reverse cholesterol transport [RCT] pathway. CETP gene variants such as-629C/A that affect HDL cholesterol directly, modulates CETP gene transcriptional activity. This study was aimed to determine influence of-629C/A polymorphism of CETP in statin effects with regard to plasma HDL cholesterol levels. In this descriptive-analytical study, 196 adult patients with LDL-C more than 120mg/dL were divided into two groups base on lovastatin and atorvastatin using. Lipid profile was measured in all subjects before and after treatment and-629C/A polymorphism of CETP promoter was studied using polymerase chain reaction/restriction fragment length polymorphism method. Data were compared with paired t-test and ANOVA in SPSS software. Cholesterol was decreased and HDL was increased in AA genotype more than other genotypes by lovastatin, but ApoA1 was increased in CC genotype. ApoA1 also was increased in CC genotype more than AA or AC genotypes by atorvastatin. In CC genotype, lovastatin and specially atorvastatin increased ApoA1 in HDL particles more than other genotypes. Therefore, treatment with lovastatin and atorvastatin is more effective in patients with CC genotype for raising HDL particles activity

[Effect of allium sativum l. extract on acid and pepsin secretion in basal condition and stimulated with vag stimulate in rat]

Garlic is used world wide to give flavor to foods as pecols ect. by different nations specially by Iranian society. The dominant believe is, the garlic therapeutic effects on patients with gastric discomfort and digesting problems. In this study we aimed to investigate the garlic effect on gastric acid and pepsin in both basic and stimulated condition by electrical stimulus of vogues nerve in rat. In an experimental study two groups of 12 wistar rats were selected, to make the animal unconscious, 50[mg/kg] Sodium tiopantal were given ip. and each rat was tracheostomized, laparatomized, gastrodeodbnostomized and then 100[mg/kg] of garlic extract dissolved in 9% saline was introduced to stomach of animal. The vagus nerves of both side of the neck released from carotid sheet and stimulated with ISmillivolts, frequency 4 Herts and 1 milisecond wide. The stomach secretions then washed out in following stages; first base, second base, vagus stimulated conditions and reverse to base. The acid amounts of washing were measured by titrometry and pepsin amounts were measured with Anson technique. The acid and pepsin secretion were significantly increased in rats received garlic extracts [p<0.000 p<0.05 respectively]. Stimulation by vagus nerves in control group significantly increased the level of acid [p<0.05] and pepsin [p<0.05] and garlic treated group had similar secretion rate to stimulated group. Furthermore there were no significant relationship between sex of studied rats. Consumption of garlic in the diet has lots of benefits for digestion of foods, so it can be beneficial for those patients with digestive problems, however it should be noted that people with digestive dysfunction related to increased level of gastric acid or pepsin must avoid garlic consumption. Therefore patient with gastritis and duodenal ulcer are not allowed to take garlic in their diet

[Effect of allium sativum extract on acid and pepsin secretion in basal condition and stimulated with pentagastrin in rat]

Allium Sativum [garlic] is used widely in the world and especially in Iran. This plant is used in cooking food as an odorant. In Iran it is believed that it is useful for gastrointestinal disorders. So in this study the effect of Allium Sativumextract on acid and pepsin secretion in rat is investigated. This experimental study is performed on two groups of rats [12 in each group: control group and allium sativum group]. After anesthesia with nesdonal [50 mg/kg, ip], rats had gone under surgical tracheotomy, laparatomy and gasterodeodenostomy. In garlic group Allium Sativum extract [100mg/kg] was introduced into the stomach by gasterodeodenostomy canula. In order to stimulation of acid and pepsin secretion, Pentagastrin was used [25mcg/kg, ip]. Stomach secretion was washed out and acid was measured using titerimetery and pepsin using Anson method. Data was analyzed using T test. Allium Sativum caused a meaningful increase in acid and pepsin secretion in garlic group comparing to control group [p<0.001]. Pentagastrin also increased acid and pepsin secretion in control group [p<0.001]. Using garlic in nutritional regimen causes an increase in acid and pepsin secretion in those using this plant
