Abstract
Prunus armeniaca L. (Apricot) is a tree cultivated in different parts of the world. Apricot kernel as a good dietary supplement has shown antioxidant, anti-inflammatory and other pharmacologic properties which suggest that it may be functional as an anticolitis agent. In this study we evaluated the effects of apricot kernel extract and oil on ulcerative colitis in rats. Rats were fasted for 36 h before the experiment. Colitis was induced by intra-rectal instillation of 50 mg/kg trinitrobenzene sulfonic acid in male Wistar rats. Treatments were started 6 h after colitis induction and continued every 24 h for 5 days. Apricot kernel extract (100, 200, 400 mg/kg p.o. and 100, 400 mg/kg i.p.) and apricot kernel extract/oil (100, 200, 400 mg/kg p.o.) were used as experimental treatments and prednisolone (4 mg/kg p.o. or i.p.) was used as reference drug. On the day 6, colon tissue was removed and macroscopic and pathologic parameters were evaluated. Ulcer index and total colitis index as representative of macroscopic and histologic parameters respectively showed ameliorating effects in experimental groups especially those treated by intraperitoneal administration route. Results also demonstrated that oil fraction was not able to potentiate the effects of extract. These data suggest that apricot kernel extracts (with or without oil) can be introduced for further mechanistic and clinical studies as a complementary medicine for inflammatory bowel disorders.

Abstract
One of the most important and serious disorders of gastrointestinal tract is acute pancreatitis which in severe form is associated with high mortality rate particularly in the presence of systemic inflammatory response and multiple organ failure. Apoptosis linked to oxidative stress has been shown in the pancreas of the patients with acute pancreatitis. Lithium, one of the most effective drugs for the treatment of bipolar disorder, also has dramatic effects on preventing cell damage and apoptosis. Also lithium has shown anti-inflammatory effects in some animal studies. This study was designed to investigate the possible effect of lithium chloride in acute pancreatitis. Induction of acute pancreatitis was performed in male mice (25-30 g) by five intraperitoneal (i.p.) injection of cerulein (50 μg/kg) with 1 h intervals. Lithium chloride (10, 20 and 30 mg/kg) was administered i.p. 15 min before the induction of pancreatitis. Six h after the last injection of cerulein, the animals were sacrificed and biochemical as well as histopathological analysis was performed. Pretreatment with 20 mg/kg i.p. of lithium chloride reduced significantly the inflammatory response in cerulein-induced acute pancreatitis by ameliorating pancreatic edema and leukocyte infiltration, attenuating amylase and lipase serum levels, and myeloperoxidase activity compared to control group (p<0.05). Two other administered doses namely 10 and 30 mg/kg were found ineffective. In this study our findings demonstrate that lithium can dose dependently exhibit protective effect against cerulein-induced acute pancreatitis.

Abstract
Prunus divaricata (Alloocheh) is a small tree cultivating in Iran, Middle East and central Asia. Prunus genus has many species with anti-oxidant, anti-hyperlipidemia and anti-hyperglycemia effects. In the present study the anti-diabetic and anti-hyperlipidemic effects of P. divaricata fruits were examined in normal and streptozotocin (STZ)-induced diabetic rats. Both groups, control and reference rats received normal saline and glibenclamide respectively. Test groups were treated with Prunus freeze dried juice (PFDJ, 200, 400, 800 mg/kg) and Prunus freeze dried extract (PFDE, 100, 200, 400 mg/kg) started at the 3(rd) day of the experiment and continued for 27 days thereafter. Weight changes of animals were checked periodically. Fasting blood glucose (FBG) level as well as serum triglyceride (TG), total cholesterol (TC), high density lipoprotein (HDL) and low density lipoprotein (LDL) cholesterol were determined. Different treatments had no significant effect on body weight increments of normal rats, while in diabetic rats, PFDJ (800 mg/kg) and PFDE (400 mg/kg) opposed with weight loss. In acute phase of experiment (0-8 h of 3(rd) day), none of tested fractions were effective in reducing FBG and serum lipids of normal rats. During the sub-acute phase (13(th) and 30(th) days) however, the greatest test doses of PFDJ (800 mg/kg) and PFDE (400 mg/kg) induced hypoglycema. In diabetic groups, PFDJ and PFDE, at all test doses, could diminish FBG during sub-acute phase of the experiment. In addition, PFDJ and PFDE at most examined doses could diminish TG significantly and they were also effective on cholesterol derivatives in different magnitude.

Abstract
Barley (Hordeum vulgare L.) is the world's fourth most important cereal crop after wheat, rice and maize. It is readily available with reasonable cost, and has the highest amount of dietary fiber among the cereals which may be beneficial for metabolic syndrome. In the present study, the effect of hydroalcoholic extract of barley seeds and a protein enriched fraction on blood glucose of normal and streptozotocin (STZ)-induced diabetic rats (STZ, 55 mg/kg, i.p) were investigated. Normal and diabetic male Wistar rats were treated daily with normal saline (1 ml), barley hydroalcoholic extract (BHE) (0.1, 0.25, 0.5 g/kg), protein enriched fraction (PEF) (0.1, 0.2, 0.4 g/kg) and glibenclamide (1 and 3 mg/kg), separately and the treatment was continued for 11 days. Blood samples were taken at 0, 1, 2, 3, 9 h in the first day and the days 5 (120 h) and 11 (264 h) for measuring the blood glucose levels (BGL). Our results indicated that none of the BHE and PEF, were effective to reduce BGL in normal or diabetic rats in acute phase of treatment (1(st) day). Nevertheless, BHE at doses of 0.25 and 0.5 g/kg, were only effective in detracting BGL of diabetic rats after 11 days of continued daily therapy. Moreover, BHE restored body weight of diabetic rats at the end of treatment. Glibenclamide had also hypoglycemic action in normal and diabetic rats after both acute and extended treatments. These findings suggest that barley seeds hydroalcoholic extract, has a role in diabetic control in long term consumption, and this effect might be at least due to its high fiber content. More detailed studies are warranted to demonstrate its mechanism of action and identify active components.

Abstract
Carum carvi L. (Apiaceae family) or caraway is a common household plant grown around the world including Iran. Caraway fruits are used as flavoring agent in foods and beverages, and have various traditional uses in ethnomedicine. Anti-inflammatory, spasmolytic, antimicrobial, antioxidant, carminative and immunomodulatory properties of caraway suggest that it might exert beneficial effects on inflammatory bowel disease (IBD). Therefore, this study was carried out to investigate the effects of caraway hydroalcoholic extract (CHE) and its essential oil (CEO) in an immunological model of colitis in rats induced by trinitrobenzene sulfonic acid (TNBS). Different doses of CHE (100, 200, 400 mg/kg) and CEO (100, 200, 400 μl/kg) were administered orally (p.o.) and also doses of CHE (100, 400 mg/kg) and CEO (100, 400 μl/kg) were given intraperitoneally (i.p.) to the separate groups of male Wistar rats (n=6). Administration of the doses started 6 h after induction of colitis and continued daily for 5 consecutive days. Wet colon weight/length ratio was measured and tissue damage scores as well as indices of colitis were evaluated both macroscopically and histopathologically. CHE and CEO at all doses tested were effective in reducing colon tissue lesions and colitis indices and the efficacy was nearly the same when different doses of plant fractions were administered p.o. or i.p. Administration of prednisolone (p.o., 4 mg/kg), Asacol® (mesalazine microgranules, p.o., 100 mg/kg) and hydrocortisone acetate (i.p., 20 mg/kg) as references were effective in reducing colon tissue injures as well. These data suggest that caraway fractions are both effective and possess anti-colitic activity irrespective of the dose and route of administration.

Abstract
Cydonia oblonga Miller (Quince) from Rosaceae family is a fruit tree cultivated in many countries mainly in Iran. This study was carried out to investigate the effect of quince juice (QJ) and quince hydroalcoholic extract (QHE) on ulcerative colitis (UC) induced by TNBS (trinitrobenzene sulfonic acid) in rats. Rats were grouped (n=6) and fasted for 36 h before colitis induction. TNBS was instilled into the colon with a hydroalcoholic carrier and then treatments were made for 5 days starting 6 h after colitis induction with different doses of QJ (200, 400, 800 mg/kg), QHE (200, 500 & 800 mg/kg) orally, QJ (400 mg/kg) and QHE (200 and 500 mg/kg) intraperitoneally. The colon tissue was removed and tissue damages were scored after macroscopic and histopathologic assessments. Albeit the examined doses of QJ and QHE were apparently effective to reduce the extent of UC lesions, only the greatest doses (500 and 800 mg/kg) resulted in significant alleviation. Weight/Length ratio as an illustrative of tissue inflammation and extravasation was also diminished with quince treatments while the results correlated with macroscopic and histopathologic evaluations. These data suggest that QJ and QHE were effective to diminish inflammation and ulcer indices in this murine model of acute colitis. Although QHE with different doses was effective in induced colitis, the dose and/or route of administration dependency was not confirmed. So quince fractions could be considered as a suitable anticolitic alternative, however further studies are needed to support this hypothesis for clinical setting.

Abstract
Trinitrobenzene sulfonic acid (TNBS)-induced colitis is one of the most common methods for studying inflammatory bowel disease in animal models. Several factors may, however, affect its reproducibility, rate of animal mortality, and macroscopic and histopathological outcomes. Our aim was to validate the main contributing factors to this method and compare the effects of different reference drugs upon remission of resultant colon injuries. TNBS was dissolved in 0.25 ml of ethanol (50% v/v) and instilled (25, 50, 100 and 150 mg/kg) intracolonically to the male Wistar rats. After determination of optimum dose of TNBS in male rats and assessment of this dose in female rats, they were treated with reference drugs including dexamethasone [1 mg/kg, intraperitoneally (i.p.) and 2 mg/kg, orally (p.o.)], Asacol (mesalazine, 100 mg/kg, p.o.; 150 mg/kg, enema) and hydrocortisone acetate (20 mg/kg, i.p.; 20 mg/kg, enema) which started 2 h after colitis induction and continued daily for 6 consecutive days. Thereafter, macroscopic and microscopic parameters and clinical features were assessed and compared in different groups. We found that the optimum dose of TNBS for the reproducibility of colonic damage with the least mortality rate was 50 mg/kg. Amongst studied reference drugs, hydrocortisone acetate (i.p.), dexamethasone (i.p. and p.o.) and Asacol (p.o.) significantly diminished the severity of macroscopic and microscopic injuries and could be considered effective for experimental colitis studies in rats . Our findings suggest that optimization of TNBS dose is essential for induction of colitis under the laboratory conditions; and gender exerts no impact upon macroscopic and histological characteristics of TNBS-induced colitis in rats. Furthermore, the enema forms of hydrocortisone and Asacol are not appropriate reference drugs.

Abstract
Allium elburzense (A. elborzense, Alliaceae), a plant rich in saponins, is an edible vegetable in northern Iran with a folk background use as antidiabetic which has not yet been examined for this indication. To evaluate the antidiabetic potential of A. elburzense, its hydroalcoholic (HdAE) and butanolic extracts (BuE) were examined. The acute (1, 2, 3, 4, 8 h) and sub-acute (11 days) effects of oral (p.o.) and intraperitoneal (i.p.) administration of HdAE and BuE of A. elburzense bulbs in different doses were evaluated on blood glucose levels of normal and streptozotocin (STZ, 55 mg/kg body weight)-induced diabetic rats. Glibenclamide (1 mg/kg b.w.) was used as reference drug. Sub-acute treatment with HdAE for 11 days reduced significantly blood glucose levels in diabetic rats (at least P<0.05), while BuE was effective only following i.p. administration (P<0.01). Acute administration did not reduce blood glucose level in normal and diabetic animals. It is concluded that HdAE of A. elburzense exhibited a significant antihyperglycemic activity following chronic administration. These results provide evidence for potential use of A. elburzense in diabetes mellitus considering the fact that this plant is endemic to a location of Iran where diabetes is a high prevalence disorder.

Abstract
Rosmarinus officinalis L. (Family Lamiaceae) popularly named rosemary, is a common household plant grown around the world, including Iran. Rosemary aerial parts are used as flavoring agent in foods, beverages, and cosmetic preparations and have various traditional uses in ethnomedicine including: analgesic, anti-inflammatory, anti-rheumatic, spasmolytic, carminative and choleretic applications. This study was carried out to investigate the effects of rosemary leaves hydroalcoholic extract (RHE) and essential oil (REO) in a well-defined model of experimental colitis induced by trinitrobenzene sulfonic acid (TNBS) in rats. Different doses of RHE (100, 200 and 400 mg/kg) and REO (100, 200 and 400 μl/kg) were administered orally and intraperitoneally (100, 400 mg/kg and 100, 400 μl/kg) to male Wistar rats (n=6), 6 h after colitis induction and continued for 5 days by intracolonic instillation of 0.25 ml TNBS (80 mg/kg)/ethanol 50% v/v. Wet colon weight/length ratio was measured and tissue damage scores as well as indices of colitis were evaluated both macroscopically and histopathologically. RHE and REO at all test doses used were effective to reduce colon tissue lesions and colitis indices while greater doses were significantly effective to diminish histopathologic parameters irrespective to the route of administration. Administration of oral prednisolone, Asacol(®) (mesalazine microgranules) and parenteral hydrocortisone acetate were effective to reduce colon tissue injures as well. These data suggest that RHE and REO are both effective to possess anti-colitic activity, and reinforce the use of this plant as a remedy for inflammatory bowel diseases in traditional medicine.

Abstract
A simple and reliable reversed-phase high performance liquid chromatographic (HPLC) method was developed, validated and applied for determination of budesonide and its novel synthesized hemiesters in colon specific formulations and dissolution media. The method was employed on a μ-Bondapak C(18) column (250 mm × 4.6 mm, 5 μm) at ambient temperature. The mobile phase consisted of acetonitrile: monobasic potassium phosphate containing orthophosphoric acid (55:45, pH 3.2) at a flow rate of 1 ml/min. The UV detection wavelength was set at 244 nm and 50 μL of sample was injected into the HPLC system. Dexamethasone was used as the internal standard. The retention times for internal standard and budesonide were 4.5 and 7.2 min, respectively. The method was linear in the concentration range of 1-20 μg/ml of budesonide (R(2)>0.999). Limit of detection and limit of quantitation were 0.05 and 0.5 μg/ml, respectively. The method presented the requisite accuracy, selectivity, sensitivity and precision and showed good resolution for separation of the drug and related derivatives in the presence of excipients. The proposed method was successfully used for analysis of the drug and its derivatives in dissolution media and oral colon specific formulations prepared in our laboratory with enough reproducibility.

Abstract
BACKGROUND AND THE PURPOSE OF THE STUDY Budesonide is the drug of choice for treatment of active inflammatory bowel disease (IBD). The aim of this study was to develop budesonide pellets based on a novel colon drug delivery system (CODES). METHODS Pellet cores containing lactulose or mannitol were prepared by extrusion/spheronization and coated with an acid soluble polymer (Eudragit E100), hydroxypropylmethyl cellulose (HPMC) and an enteric coat (Eudragit FS 30D) sequentially. In vitro drug release of coated pellets was studied using USP dissolution apparatus type II in buffers of pH 1.2 (2 hrs), pH of 7.4 (4 hrs) and pH of 6.8 containing 8% rat cecal contents (RCC) (18 hrs). The efficacy of the optimized formulation (containing 50% lactulose coated with Eudragit E (30% w/w) and Eudragit FS 30D (12% w/w)) was evaluated against 2, 4, 6-trinitrobenzenesulfonic acid (TNBS)-induced colitis in rats. RESULTS The results of the kind of bacteria in vitro dissolution tests indicated absence of drug release in pHs of 1.2 and 7.4 and controlled release in buffer of pH 6.8 containing RCC. It was found that release rate was controlled by the type and amount of polysaccharide and the thickness of the acid soluble layer. The prepared formulation showed promising results in alleviating the conditions of experimental model of colitis. CONCLUSION The results of this study suggest that pellets based on CODES technology could be useful for colonic delivery of budesonide.

Abstract
Doxorubicin is a broad spectrum antibiotic used in the treatment of cancers. Its dose dependent cardiotoxicity is the most serious side effect causing withdrawal of drug from hard chemotherapeutic regimen. Statins are shown to be cytotoxic in concentrations higher than the effective doses for the treatment of hypercholesterolemia (40 mg/day). Co-administration of statins and chemotherapeutic agents suppose to be synergic although there are some controversies in the literature. In this study, cytotoxic effects of doxorubicin alone and in combination with simvastatin on Hela tumor cell line were evaluated. Different concentration of doxorubicin and simvastatin were added to the cultured cells and incubated for 72 h. Cell survival was evaluated using MTT and trypan blue exclusion assays. The results indicated that simvastatin in low concentration (0.25 μM) seems to be growth stimulator although cell viability was reduced in concentrations of ≥2 μM. Doxorubicin alone at all tested concentrations (0.1, 1 and 2 μM) was a cell growth inhibitor. It was also shown that percent cell viability was reduced in a decreasing manner with the following protocols: 1) co-administration of doxorubicin and simvastatin in different concentrations; 2) addition of simvastatin after incubation of cells with doxorubicin and 3) addition of doxorubicin after incubation of cells with simvastatin. It could be concluded that between 3 tested protocols combination of doxorubicin and simvastatin after 72 h incubation, showed the highest cytotoxicity against Hela cells.
