Patients' concepts and attitudes about diabetes

ObjectiveTo evaluate the concepts and attitudes of patients and their immediate family members towards diabetes, its complications, and treatment.Research Design and MethodsA total of 654 patients with poorly controlled diabetes and 216 of their immediate family members were interviewed regarding their concept about diabetes, its complications, diet, exercise, drug therapy, and understanding about insulin.ResultsThere was lack of awareness about diabetes and its complications among the patients of diabetes. Majority of obese patients and their close family members failed to accept that they were obese. Child birth, menopause, and tubal ligation in female patients were wrongly attributed as a cause of obesity. There were major misconceptions about diet, exercise, and insulin therapy. More than 90% of study subjects had a misconception that all sweet fruits are prohibited and all bitter vegetables are beneficial. Temporary discontinuation of drug therapy was found in 189 cases. The lack of awareness and various misconceptions had no statistical relationship with the educational background of the patients.ConclusionAmong patients of poorly controlled diabetes and their close family members, there was a gross lack of knowledge of complications of diabetes, causes of obesity, treatment of diabetes, and use of insulin. Denial of obesity was commonly observed. Linking obesity with tubal ligation in female patients not only is appalling but may possibly be a hindrance to family planning program. Level of education had no bearing on these misconceptions.     

Focal adhesion kinase (FAK) expression in normal and neoplastic lymphoid tissues

Focal adhesion kinase (FAK) is a protein tyrosine kinase essential for intracellular regulatory events, such as cell growth, differentiation, migration and tumor metastasis. The aim of this study was to analyze the expression of FAK protein in a series of normal and neoplastic lymphoid tissues.An anti-FAK antibody was used to study the protein expression in paraffin-embedded samples of normal and neoplastic, hematolymphoid and non-hematolymphoid tissues by immunohistochemistry. In normal hematolymphoid tissue, the strongest expression of FAK was detected in germinal center and marginal-zone B cells; positive staining was also found in mantle zone B cells. In human lymphomas, FAK was expressed mostly in B-cell lymphomas and was predominantly negative in T-cell lymphoma. In Hodgkin lymphomas, FAK was found only in the neoplastic cells of lymphocyte predominant type, whereas the tumor cells of the classical form were FAK-negative.We demonstrate for the first time the expression of FAK in paraffin-embedded hematolymphoid tissue samples. Its differential expression in lymphomas may be of relevance for some B-cell neoplasms by using it as an additional marker to distinguish B- from T-lymphoblastic leukemia/lymphoma to further differentiate lymphocyte predominant from classical Hodgkin lymphoma.     

Hypolipidemic effect of triphala in experimentally induced hypercholesteremic rats

Hypercholesteremia is one of the risk factors for coronary artery disease. The present study highlights the efficacy of Ayurvedic herbal formulation Triphala (Terminalia chebula, Terminalia belerica, and Emblica officinalis) on total cholesterol, Low density lipoprotein (LDL), Very low density lipoprotein (VLDL), High density lipoprotein (HDL) and free fatty acid in experimentally induced hypercholesteremic rats. Four groups of rats were employed namely control, Triphala treated, hypercholesterolemia rats (4% Cholesterol + 1% cholic acid + egg yolk) and Triphala pre-treatment in hypercholesteremic rats. Results showed significant increase in the total cholesterol, LDL, VLDL, and free fatty acid in hypercholesteremic rats were significantly reduced in Triphala treated hypercholesteremic rats. The data demonstrated that Triphala formulation was associated with hypolipidemic effects on the experimentally induced hypercholesteremic rats.     

Antioxidant property of α-asarone against noise-stress-induced changes in different regions of rat brain

Free radicals and other reactive species are considered to be an important causative factor in the development of neurodegenerative diseases. Recent reports have indicated that exposure to loud noise generates excess oxygen free radicals (OFR) in the brain. Antioxidant properties of medicinal plants are attracting more and more research in medicine, to counteract OFR and to minimize the neurodegenerative processes. The drug alpha-asarone (3, 6 and 9 mg kg(-1) body weight, i.p., for 30 days), one of the active principle components of Acorus calamus Linn., was administered intraperitoneally 1/2 h before the animals were exposed to noise-stress (100 dB for 4 h d(-1), for 30 days). We investigated whether 30 days exposure of noise can produce an oxidative stress. Further, if yes then, could alpha-asarone counteract the stress. This was verified by measuring the activity of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), levels of reduced glutathione (GSH), Vitamin C, Vitamin E, protein thiols and lipid peroxidation (LPO) in different regions of the rat brain. All the three doses of alpha-asarone had an effectively protective role by normalizing the increased SOD and LPO, decreased CAT, GPx, GSH, Vitamins C and E and protein thiols due to noise exposure. Thus, action of alpha-asarone against noise-stress may be due its antioxidant property. Our data proved that antioxidant property of alpha-asarone against noise-stress induced changes in the rat brain. Further, more clinical studies are required to investigate effectiveness of the alpha-asarone in noisy environment in human subjects.     

Infections in the gynaecological tract

In the context of infections in the body, those that occur in the gynaecological tract are less common and perhaps less clinically significant compared with other body sites. However, a few infections are important in view of their association with pathological sequelae such as tumour formation or pelvic inflammatory disease complex.This review will discuss some of the most relevant infections, first under histology, which will be further subdivided into locations in the genital tract and then under cytology, which focuses mainly on the infections seen in cervical cytology samples. There will be only brief mention of the less common infections or those that do not produce diagnostic challenges or lead to significant complications.
