Imidazolidine are five-member heterocyclic compounds having two nitrogens in the ring. There are two carbonyls in the ring, one of them between the two nitrogens. The five positions of the ring are numbered and, as such, there are four points of functionality, one at the 1 position, one at the 3 position and two at the 5 position in their ring structure respectively and thus exhibiting potent as well as wide range of pharmacological activities. A series of, phenylene methylene hydantoin were synthesized. Benzaldehyde derivatives reacted with imidazolidine to yield the respective derivatives. This reaction follows the Knoevenagel condensation reaction mechanism by which ethanolamine abstract a proton from heterocyclic ring and a carbanion ion is generated. The structure of synthesize compounds were supported by IR, NMR and mass spectral data. The synthesized compounds were screened for their in vitro antidiabetic activity by α-amylase, α-glucosidase inhibition, glucose diffusion inhibitory test and the potential compounds tested for in vivo activity by blood glucose changes in type 2 diabetic...

Aspirin is a common medication used to treat pain, fever and inflammation. It shows the property of polymorphism and two polymorphic forms were characterized till now (Form I and Form II). Albendazole is another common medication used for the treatment of variety of parasitic worm infestations. This drug also shows polymorphism where two forms (Form I and Form II) of it were characterized till date. Various commercial aspirin and albendazole tablets were collected, powdered and after proper clean up procedure their melting points were determined to identify the polymorphic form of each drug sample. The detection of polymorphic form was further carried out by infra red spectral analysis. It was found that all the commercial aspirin samples under study belong to the polymorphic form II which is usually used in drug formulation. Polymorphic studies on commercial albendazole tablets showed that all the samples under investigation belong to the polymorphic form I which is commonly...

Exacum lawii is folklore medicinal herb, boiled with oil and used traditionally for ocular infection. The aim of the present study is to evaluate the in-vitro antibacterial and antifungal activity against ocular infection. Ethanolic extract, petroleum ether extract and volatile oil were extracted from Exacum lawii whole plant. Antibacterial activity and antifungal activity against strains causing ocular infection were evaluated and Himalaya Optha-care Eye Drop was used as standard. The antimicrobial susceptibility was performed by agar disc diffusion assay method. The minimum bactericidal concentration (MBC) and minimum fungicidal concentration were determined for each extract and volatile oil by subculturing the samples. The volatile oil and the extracts of Exacum lawii showed bactericidal and fungicidal activities against some strains of bacteria and fungi causing ocular infection. Minimum bactericidal concentration for volatile oil was found in range of 3.125 mg/ml to 12.25 mg/ml, for ethanolic extract 6.25 mg/ml to 25 mg/ml and for petroleum ether extract 25 mg/ml to 50 mg/ml. Minimum fungicidal concentration of volatile oil was found to be...

The aim of this experiment was to find out the in-vitro effects of the extracts of certain plants, considered to have medicinal value, on the erythrocyte model. The plants, selected for the study, were Tulsi (Ocimum tenuiflorum), Neem (Azadirachta indica) and Amla (Phyllanthus emblica).Three different concentrations of leaf extracts were prepared using tris-HCl, namely 0.3 mg/ml, 0.15 mg/ml and 0.075 mg/ml and their effects on the RBCs in blood samples were studied using optical microscope. Various morphological changes like haemagglutination, shrinking, swelling, distortions, granulation of the membrane and bursting of the cells were observed. The degree of occurrence of a certain morphological change on a particular blood type varied with a variation in its concentration. Also, the same concentration of the extract showed different morphological changes with different blood groups indicating that the blood type is also important in the effects shown by the cell membranes. The crude leaf extracts of medicinal plants significantly affected the integrity and thus, the morphology of the...

The study was intended to evaluate the effectiveness of patient counselling in improving the quality of life (QOL) and knowledge, attitude and practices (KAP) of hypertensive and diabetic patients in a private educational institution. The study was conducted for a period of six months with the help of validated KAP and QOL questionnaire. Impact of patient counselling was studied by comparing the KAP and QOL score obtained after each subsequent patient counselling sessions. Data analysis was done by SPSS 16.1. Among 83 patients enrolled in the study, 40 were males and 43 were females. Out of 83 patients, 32 (38.55%) were diagnosed as hypertensives and 51 (61.44%) were diabetics. It was found that most of the hypertensives and diabetics were in the age group of 51-60 years. It was further found that the scores of knowledge (2.72 ± 1.80 to 4.88 ± 0.97), attitude (3.41 ± 1.73 to 4.94 ± 0.98) and practice (3.56 ± 1.86 to 6.28 ± 1.78) of hypertensive patients increased from baseline to second follow-up...
