Bitter Honey Intoxication and Hazardous Arrhythmias: Two Cases
Ozturk S et al.
Konuralp Tip Dergisi , 2011,
Abstract: Bitter-honey is named as a kind of honey which is produced by beesfrom the nectar of Rhododendron luteum and Rhododendron ponticumcontaining grayanotoxin. The patients with bitter honey intoxicationadmit to emergency room with heart symptoms including bradycardia,hypotension and syncope. These symptoms are mainly due to heartconduction defects such as complete AV block, asystole, and sinusbradycardia. Herein, we presented two cases with bitter-honeyintoxication. Although symptoms presented by patients were similar intwo cases, different conduction disorders including high-degree AVblock and complete AV block were seen in first case, and nodal rhythmwere seen in second case. In conclusion, the physicians should managethe patients with similar symptoms on admission for life-threateningarrhythmias due to bitter honey intoxication.
A Rare Cause of Foot Pain in the Emergency Room: an Aortic Dissection Case
Korkut S et al.
Konuralp Tip Dergisi , 2010,
Abstract: Aortic dissection is a fatal condition that can originate from any point of the aorta between the root of the aorta and iliac bifurcation so it necessitates early diagnosis and treatment. The most common sign is pain and it may appear in the chest, neck, back or interscapular area. Additionally, it may present with anxiety, syncope or high blood pressure. In this article, we aimed to present a 46 year old female patient admitted to our emergency department due to paresthesia and pain in the right foot and took the diagnosis of DeBakey Type 1 aortic dissection.

Abstract: Acute coronary syndrome with thrombus in more than one vessel is arare clinical and angiographic situation. But generally this situation may progress to mortality because of the affected myocardial tissue's size. We aimed to present three patients with acute coronary syndrome who have thrombus in two vessels and treated successfully.
The One phase surgical approach of simultaneous right pulmonary and hepatic hydatid cysts through the transthoracic route
Karapolat S et al.
Konuralp Tip Dergisi , 2010,
Abstract: Simultaneous right lung and liver dome hydatid cyst lesions is to be found as frequently. A 23-year-old female patient was operated by right thoracotomy and phrenotomy due to ruptured hydatid cyst on lateral basal segment of lower lobe of the right lung and intact hydatid cyst on right lobe of the liver. No recurrence was observed clinically and radiologically during 3 months of follow-up period. The surgical approach of simultaneous right pulmonary and hepatic hydatid cysts through the transthoracic route is a safe technique and also has a positive effect on the patient’s life comfort.
Influence of functional silanes on hydrophobicity of MCM-41 synthesized from rice husk
S. Chiarakorn et al
Science and Technology of Advanced Materials , 2007,
Abstract: Mesoporous molecular sieve MCM-41 was synthesized from rice husk and rice husk ash, called RH-MCM-41 and RHA-MCM-41. The sol–gel mixtures were prepared with molar composition of 1.0 SiO2: 1.1 NaOH: 0.13 CTAB: 0.12 H2O. After calcination, the polarity of MCM-41 still remained on its surface due to the existence of some silanol groups. In this study, both RH-MCM-41 and RHA-MCM-41 were silylated with two different functional silanes trimethylchlorosilane (TMCS) and phenyldimethylchlorosilane (PDMS) in order to reduce the surface polarity. The efficiency of silylation was determined based on the amount of moisture adsorbed using thermogravimetric analysis (TGA). The structure of silylating agents and silica templates were found to be important parameters affecting the hydrophobic property of the MCM-41 surface. The post-grafting silylation with aliphatic silane can decrease the surface polarity better than that with aromatic silane, probably due to less sterric hindrance effect. Thus, the surface hydrophobicity of MCM-41 can be improved by the silylation of small molecular silane on RH-MCM-41.
Consolidation of nanocrystalline hydroxyapatite powder
S. Ramesh et al
Science and Technology of Advanced Materials , 2007,
Abstract: The effect of sintering temperature on the sinterability of synthesized nanocrystalline hydroxyapatite (HA) was investigated. The starting powder was synthesized via a novel wet chemical route. HA green compacts were prepared and sintered in atmospheric condition at various temperatures ranging from 900–1300 °C. The results revealed that the thermal stability of HA phase was not disrupted throughout the sintering regime employed. In general, the results showed that above 98% of theoretical density coupled with hardness of 7.21 GPa, fracture toughness of 1.17 MPa m1/2 and Young's modulus of above 110 GPa were obtained for HA sintered at temperature as low as 1050 °C. Although the Young's modulus increased with increasing bulk density, the hardness and fracture toughness of the sintered material started to decline when the temperature was increased beyond 1000–1050 °C despite exhibiting high densities >98% of theoretical value. The occurrence of this phenomenon is believed to be associated with a thermal-activated grain growth process.

Abstract: Nature has always been stands as a golden mark to amplify the outstanding phenomenon of symbiosis. Ayurvedic remedies for diabetes are usually mixed formulations containing blood sugar lowering herbs in combinations with immunomodulator, detoxicants with the rationale behind such formulations being provided by modern research. Polyherbal formulations have plant-based pharmacological agents which may exert synergistic, potentiative, agonistic antagonistic actions by virtue of its diverse active principles within themselves. These pharmacological principles work together in a dynamic way to produce maximum therapeutic efficiency with minimum side effects. Medicinal plants existing even before human being made their appearance on the earth. The development procedures of herbal drugs for world-wide use has to been different form that of synthetic drugs. The raw materials for Ayurvedic medicines were mostly obtained from plant sources in the form of crude drugs such as dried herbal powders or their extracts or mixture of products or mixture of product. Apart from these systems there has been a rich heritage of Ethno-botanical usage of herbs by various colorful tribal communities in the country. Hence, the present review provides the supportive evidence consideration of a therapeutic approach combining the beneficial effects of Polyherbal preparation in association with adaptive physical activity for effective management of diabetic complications.

Abstract: In this study, a discriminative dissolution method was developed for Cephalexin OD (orally disintegrating) tablets 750mg. The solubility and stability of the cephalexin API was determined in ten different solutions. In that 0.01N HCl, glycine buffer pH 3-0, acetate buffer pH 4.5 and water gave good stability and the solubility. Dissolution profiling of cephalexin OD tablets 750mg of single batch was done with the selected media containing varying concentration of surfactants (tween 80 and Sodium lauryl sulphate- SLS). The release profile is compared with that of the control media. The media that gave discriminately faster release than that of the control were found to be 0.01N HCl with 0.75% of tween 80, 0.01N HCl with 0.5% of SLS, acetate buffer with 1% of tween 80 and water with 0.5% of SLS. With the selected media, dissolution profile was done on the three different batches of cephalexin OD tablets one with lesser polymer ratio and other with higher polymer ratio that that of the test batch. Only 0.01N HCl with 0.75% of tween 80 as dissolution medium was found to show good discrimination in the release profile with change in the formulation conditions. The discriminative dissolution method developed was validated for its specificity, accuracy, stability, linearity and precision and it passes all the parameters.

Abstract: This study was designed to investigate the ameliorative effect effect of Hygrophila auriculata (H. auriculata) on lipid peroxidation (LPO) in Nnitrosodiethylamine induced Hepatocellular Carcinoma (HCC) in rats. Experimental rats were divided into different groups: normal, NNitrosodiethylamine induced hepatocellular Carcinoma bearing rats, H.auriculata treated hepatocellular carcinoma bearing rats, (200 mg/kg body weight, doses for 28 days), Animals treated with plant extract alone for 28 days. After the treatment period of 28th day , effect of H.auriculata on LPO in serum , liver and kidney of control and experimental animals were assayed and compared. Under basal and in the presence of inducers (H2O2), the levels of LPO were increased significantly (p<0.001) in group II cancer bearing animals where as the levels of LPO in the presence of ascorbic acid and FeSO4, were not statistically different. In group III plant extract treated animals, significant decrease on LPO was observed. However, the changes in the above parameters were comparable with control.Thus, methanolic extract of H. auriculata ameliorated the LPO which is associated with the development of HCC to near normal in HCC bearing rats which could be attributed to the presence of polyphenols and flavonoids in the plant extract. Antioxidants act as radical scavenger, inhibit LPO and other free radicalmediated processes, thereby protecting the human body from various diseases.
