Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cistus laurifolius is widely used in folk medicine in Anatolia for the treatment of many ailments. The leaves of the plant are used in the form of tea in the treatment of hemorrhoids in the Western Black Sea Region and Central Anatolia. AIMS OF THE STUDY It was aimed at evaluating the anti-hemorrhoidal effects of C. laurifolus leaves in croton oil-induced hemorrhoid model in rats. MATERIALS AND METHODS The methanolic and aqueous extracts of C. laurifolius were tested for in vivo anti-hemorrhoidal efficacy using an experimental hemorrhoid model, followed by histological and biochemical analysis. Hemorrhoid was created by using croton oil on the anal region of the rats. TNF-α and VEGF mRNA expression levels were assessed using real-time PCR detections. The extract was also tested for anti-inflammatory properties, which are based on the suppression of an increase in capillary permeability caused by acetic acid. LC-QTOF-MS and RP-HPLC were used for the phytochemical analysis. RESULTS In comparison to the control, histological and biochemical assessment showed that the methanolic extract of C. laurifolius is particularly effective against hemorrhoids. The same extract group's TNF-α mRNA expression was found to be the lowest. Additionally, the methanolic extract showed a strong inhibitory effect on the increase in capillary permeability resulted on by acetic acid. Three phenolic compounds were discovered in the extracts by phytochemical analyses, while more than eighteen compounds were found by LC-QTOF-MS analysis. Five of these compounds are phenolic acid derivatives, and flavonoids constitute the majority of the group. CONCLUSION This is the first evidence from the research that C. laurifolius possesses strong anti-inflammatory and anti-hemorrhoidal properties.

Abstract
BACKGROUND Aerial parts of Malva nicaeensis All. are preferred in the prevention and treatment of intestinal infections and hemorrhoids in Turkish traditional medicine. This study is planned to evaluate the pharmacological activity of M. nicaeensis extracts on rats with acetic acid-induced colitis. METHODS The plant material was subsequently extracted with n-hexane, ethanol, and water, respectively. All of these extracts were tested for efficacy in the acetic acid-induced rat colitis model. The aqueous and polysaccharide extracts regulated cytokine levels and antioxidant parameters. Furthermore, the aqueous extract in particular regulated myeloperoxidase and caspase-3 levels in this rat model. In addition, the polysaccharide-rich fraction was separated from the aqueous extract. RESULTS The polysaccharide-rich fraction and aqueous extract regulated cytokine levels and antioxidant parameters. The aqueous extract also positively affected myeloperoxidase and caspase-3 levels. The phytochemical studies revealed that the aqueous extract had the highest phenolic content. In addition, the polysaccharide fraction was found to contain total sugars, sulfated groups, uronic acids, and total proteins in 78.4%, 0.9%, 1.5%, and 14.7%, respectively, and was rich in monosaccharide-type compounds, especially galactose (36.4%). CONCLUSIONS M. nicaeensis was discovered to be a drug lead in the future treatment of irritable bowel diseases or as a complementary therapeutic agent that aided conventional treatments.

Abstract
Leaves and aerial parts of Malva neglecta Wallr. have been traditionally used in Anatolia for the treatment of pain, inflammation, hemorrhoids, renal stones, constipation, and infertility. This study investigated the effects of M. neglecta leaves in a rat endometriosis model. The dried plant material was extracted with n-hexane, ethyl acetate, and methanol, successively. Experimental endometriosis was surgically induced in six-week-old female, non-pregnant, Wistar albino rats by autotransplant of endometrial tissue to the abdominal wall. After twenty-eight days, rats were evaluated for a second laparotomy. Endometrial foci areas were assessed, and intraabdominal adhesions were scored. Rats were divided into five groups as control, n-hexane, ethyl acetate, methanol, and aqueous extracts, as well as reference. At the end of the treatment, all rats were sacrificed and endometriotic foci areas and intraabdominal adhesions were re-evaluated and compared with the previous findings. Moreover, peritoneal fluid was collected to detect tumor necrosis factor- α (TNF-α), vascular endothelial growth factor (VEGF), and interleukin-6 (IL-6) levels, and cDNA synthesis, and a quantitative real-time polymerase chain reaction (PCR) test was done. The phytochemical content of the most active extract was determined using High-Performance Liquid Chromatography (HPLC). Both endometrial volume and adhesion score decreased significantly in the group treated with methanol extract. In addition, significant decreases were observed in TNF-α, VEGF, and IL-6 levels in animals administered methanol extract. HPLC results showed that the activity caused by the methanol extract of M. neglecta was due to the polyphenols. Taken together, these novel findings indicate that M. neglecta may be a promising alternative for the treatment of endometriosis.

Abstract
Detoxification enzymes involved in human metabolism works to minimize the potential xenobiotic-induced damage constantly. Studies have revealed that toxin accumulation plays an important role in the etiology of cardiovascular disease. This study has been designed to provide evidence of medicinal use of bentonite, turmeric (Curcuma longa L.), grape (Vitis vinifera L.) seed, flaxseed (Linum usitatissimum L.), and psyllium (Plantago ovata L.) as detoxification and cholesterol-lowering agents using a hypercholesterolemic model in mice. The potential hypocholesterolemic effects and detoxification ability of these ingredients were evaluated at the same time: Total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglyceride, glucose, aspartate aminotransferase, alanine aminotransferase, malondialdehyde, plasma total antioxidant activity, nitric acid, leptin levels and glutathione, glutathione peroxidase, lipid peroxidation, superoxide dismutase and catalase values were measured. It was determined that GBTF group (grape seed extract, bentonite, turmeric, and flaxseed), GBTP group (grape seed extract, bentonite, turmeric, and psyllium), and GBT group (grape seed extract, bentonite, and turmeric) of the tested materials decreased the serum total cholesterol concentration by 64.8, 57.5, and 48.9%, respectively, in mice fed a high cholesterol diet. In addition, it was determined that some detoxification parameters such as superoxide dismutase, catalase, glutathione, and glutathione peroxidase were statistically significantly reversed in GBTF, GBTP, and GBT groups. Flaxseed, psyllium, and bentonite clay did not show significant effects in reducing total cholesterol; however, GBTF, GBTP, and GBT groups interventions had a significant effect in reducing total cholesterol levels. Moreover, it was observed that adding flaxseed or psyllium to the GBT group increased the cholesterol-lowering effect. Therefore, it can be thought that this significant effect is due to the synergistic effect of the raw materials. When the results obtained were evaluated, it was seen that the cholesterol-lowering and detoxification effects of the combinations were higher than from the effect of natural material used alone. As a result, combinations of some of these ingredients have a positive effect on reducing the risk of cardiovascular disease.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Turkish folk medicine, leaves of Sorbus domestica are used for the treatment of burns, cough, stomachache, bradyuria, kidney stone. The fruits of this plant are used for diarrhoea. AIM OF THE STUDY This study was carried out to investigate the effect of S. domestica on ulcerative colitis induced by acetic acid in rats. MATERIALS AND METHODS The crude methanolic extract of fruits was sequentially fractionated into five subextracts; dichloromethane, diethyl ether, ethyl acetate, n-butanol and aqueous extracts. Effects of the extract, subextracts and fractions were investigated in acetic acid-induced rat colitis model. The colonic interleukin-6 (IL-6), tumor necrosis factor (TNF-α), nitrite, superoxide dismutase (SOD), glutathione (GSH), lipid peroxidation (LPO), catalase (CAT), and malondialdehyde (MDA) levels as well as the caspase-3 and myeloperoxidase (MPO) activities were measured to determine the activity. Histopathological analyzes were also performed on the colon tissue of rats. RESULTS The methanolic extract and diethylether subextract have led to a noteworthy decrease in MPO, caspase-3, IL-6, TNF-α, MDA, and nitrite levels in the colon tissue and blood. In addition, histopathological analysis results were supported by biochemical parameters. After confirmation of the activity against ulcerative colitis, the diethyl ether subextract was subjected to more chromatographic separation for the isolation of compounds 1, 2 and 3. The structures of these three compounds were elucidated as vanillic acid 4-O-α-L-rhamnopyranoside (1), protocateuic acid anhydrite (2) and trivanilloyl-(1,3,4-trihydroxybenzol) ester (3). CONCLUSION In this study, the potential of S. domestica in the treatment of colitis was investigated. Fruits of this plant were found to have important anti-inflammatory and antioxidant activities. Through isolation techniques, vanillic acid 4-O-α-L-rhamnopyranoside, protocateuic acid anhydrite and trivanilloyl-(1,3,4-trihydroxybenzol) ester were determined as the main active components of the fruits. Consequently, S domestica might be a promising candidate for upcoming use the prevention and treatment of various disorders, such as inflammatory bowel diseases, irritable bowel syndrome and Clostridium difficile infection.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Urtica dioica L. has been used traditionally for centuries. U. dioica leaves and roots are used as a blood purifier, emmenagogue, and diuretic, as well as to treat menstrual hemorrhage, rheumatism, and eczema. The present study aimed to evaluate the activity of U. dioica L. aerial parts in endometriosis rat model. MATERIALS AND METHODS To evaluate the effects of the plant in endometriosis, n-hexane, ethyl acetate (EtOAc), and methanol (MeOH) extracts were prepared from the aerial parts of the plant and utilized in a rat surgical endometriosis model. In this model, adhesion scores of endometriotic implants and the spherical volumes of ectopic uterine tissues were evaluated. In addition to these parameters, tumor necrosis factor alpha (TNF-α), vascular endothelial growth factor (VEGF), and interleukin-6 (IL-6) levels of the peritoneal fluids were evaluated. Furthermore, histopathological studies were conducted on the endometriotic tissues. RESULTS Post-treatment implant volumes and adhesion scores were significantly reduced in the reference and the MeOH extract treated groups. Significant differences were found between the peritoneal TNF-α, VEGF, and IL-6 levels of MeOH extract treated group and those of control group. Moreover, histopathological findings supported the biological activity results. Furthermore, isolation studies were conducted on the MeOH extract, which showed prominent activity in the rat endometriosis model. Rutin (1), isoquercetin (2), the mixture of kaempferol-3-O-rutinoside (nicotiflorin) (3a) and isorhamnetin-3-O-rutinoside (narcissin) (3b) (3), the mixture of kaempferol-3-O-glucoside (astragalin) (4a) and isorhamnetin-3-O-glucoside (4b) (4) were isolated from the active fraction. CONCLUSIONS The present study demonstrated that aerial parts of U. dioica exhibited promising activity in the endometriosis rat model due to its flavonoids.

Abstract
AbstractIn Turkish folk medicine, the fruits of Pyrus elaeagnifolia subsp. elaeagnifolia have been used to treat diarrhea and detoxify poisonous snake bites by enlarging the wound. The aim of the study was to confirm the ethnopharmacological usage of the plant using in vivo and in vitro models. Experimental colitis was performed under anesthesia by intrarectal administration of acetic acid in rats, and the extracts were administered orally. The colonic malondialdehyde (MDA), tumor necrosis factor (TNF-α), interleukin-6 (IL-6), and nitrite levels, in addition to the myeloperoxidase (MPO) and caspase-3 activities, were measured to determine the effects of the plant extracts. The methanol (MeOH) extract revealed a significant decrease in MPO and caspase-3 levels. The MeOH extract was found to have the highest total tannin content. It was also found to have significant antioxidant (p ˂ 0.01) and anti-inflammatory activities (p ˂ 0.05) in acetic acid induced colitis rat model . According to our results, the present study exhibited a decrease in MDA, nitrite, IL-6, and TNF-α levels in the colon tissue and blood in the MeOH extract treated group. The findings of this study can help in treating various disorders, such as Clostridium difficile infection, irritable bowel syndrome, and inflammatory bowel diseases.

Abstract
We report here a ß- thalassemia major case (homozygous IVS-1-110 G-A) associated with Familial Mediterranean Fever (FMF) (homozygous 694 Met-Val). Our patient's clinical course revealed a possible synergistic effect between colchicine and desferrioxamine (DFO) However, this could be a only a coincidence, as under colchicine therapy, fever attacks may appear, this may be the topic of a further investigation.

Abstract
Familial Mediterranean fever (FMF) is an autosomal recessive disease. It is characterized by recurrent febrile episodes in association with peritonitis, pleuritis, and arthritis. Progressive systemic amyloidosis is the most important complication of FMF that inevitably leads to chronic renal failure. Recently, the gene for FMF, MEFV, has been cloned and four missense mutations have been described: M694V, M680I, V726A, and M694I. Initial studies have suggested that the presence of the M694V mutation carries a significant risk for the development of amyloidosis. In this study, we present seven families, in which at least two individuals have been diagnosed with FMF and at least one with amyloidosis. Among 18 individuals, in whom molecular testing was performed for the four aforementioned mutations, ten had amyloidosis. None of these ten individuals was found to be homozygous for the M694V mutation. In three families, there were two sibs with amyloidosis. None of the sib-pairs with amyloidosis was found to have the same genotype. There were two or more sibs with the same genotype in four families. Only one sib from each family developed amyloidosis in these families. These results provide evidence that FMF patients without the M694V mutation are also at risk for the development of amyloidosis. Particular mutations themselves do not appear to be sufficient to explain the occurrence of amyloidosis in all cases with FMF.

Abstract
OBJECTIVES Differences in clinical manifestations of familial Mediterranean fever (FMF) between different ethnic groups have been documented. The FMF gene was recently cloned and four missense mutations (Met694Val, Met680Ile, Val726Ala, and Met694Ile) that account for a large percentage of the patients were identified. The results of initial mutation studies have led to the hypothesis that phenotypic variation of the disease may be attributable to the existence of some of these mutations. The purpose of this study was to evaluate whether this phenotypic variation is associated with the existence of particular mutations in Turkish FMF patients living in Turkey. METHODS Four missense mutations and genotype-phenotype correlation were investigated in 167 Turkish FMF patients. The patients were grouped according to the presence of the Met694Val and the Met680Ile mutations, and 12 clinical parameters were compared between the groups. RESULTS The presence of the Met694Val mutation was not found to be associated with a severe form of the disease or the development of amyloidosis. Arthritis frequency was found to be lower in the patients with homozygous Met680Ile mutation. CONCLUSIONS None of the four missense mutations is associated with a severe disease or the development of amyloidosis in Turkish FMF patients living in Turkey. The influence of unknown environmental factors and/or the presence of other genetic changes are necessary to explain the phenotypic variation of the disease and the development of amyloidosis.

Abstract
Exposure to tobacco smoke can cause irritation of the conjunctiva. We conducted this study to identify the effect of tobacco on rat conjunctiva. Animals were divided into experimental and control groups and we exposed the experimental group to tobacco smoke. Control group rats inhaled only room air. Spectrophotometric analysis of the smoke-air mixture revealed that many toxic substances were present in this compound. We found very high levels of plasma thiocyanate after exposure to smoke in experimental group animals but no increase in the control group. So, this data indicates that these animals inhaled smoke effectively in our method. After 3 months conjunctivas were examined by light and electron microscopy. In the experimental group, conjunctivas were thinned, atrophied and microvillous projections and desmosomal connections were absent in comparison with the control conjunctivas. This pathologic change is very similar to conjunctival response to chronic irritants of any type.
