Metabolic syndrome (MetS) is a name for a group of risk factors that occur together and increases the risk for coronary artery disease, stroke, and type 2 diabetes. The MetS is a clustering of components that reflect over nutrition, sedentary lifestyles and resultant excess adiposity. Metabolic Syndrome is posing a major public health challenge to the health systems in developed and developing countries. The 405 study subjects aged between 25-65 yrs from general population in Ghaziabad, India, were taken, who attended the hospital for general checkup. Complete fasting lipid profile, Blood glucose, and Hs-CRP, Lp(a) and GGT, blood urea and Serum Creatinine of subjects were evaluated. On application of ATP 3^rd criteria on the screened subject patients, they are classified. Our study found that the number of subjects having MetS was 173 (42.71% of total). In the subgroup of metabolic syndrome with diabetes, the total number of subjects was 105(25.92%) in which age wise distribution was 26 (6.41%) in 25-45 yrs and 79 (19.50%) in 45-65 yrs. In the second subgroup of metabolic syndrome without diabetes total number of subjects was 68 (16.79%) in which age wise distribution was 16 (3.95%) in 25-45 yrs and 52 (12.83%) in 45-65 yrs. The study proposes the inclusion of biochemical parameter Hs-CRP, Lp (a) and GGT in the criteria for defining cases of metabolic syndrome, so that more metabolic syndrome cases can be picked up at earliest. This issue is especially pertinent for the Indian patient population in whom cardiovascular disease is becoming increasingly common in both sexes and in age group of 25-65 yrs. There should be emphasis on detection of metabolic syndrome and intensification of targeted preventive strategies.

Dr. Anil Gupta

 Senior Lecturer, Deptt. of Physiology and Biochemistry, Eklavya dental College, Rajasthan, India.

Anemia is the reduction in quantity of haemoglobin pigment in circulating blood. It is the manifestation of chronic inflammation, infection or malignancy in the body. The study sample comprised of total 30 participants in two groups. The mean haemoglobin of cirrhotics (9.86 ± 1.8 mg/dl) was lesser in comparison to haemoglobin (13.09 ± 1.76 mg/dl) of controls significantly (p<0.0001). Further, sample t-test revealed a significant (p<0.0001) reduction in concentration of haemoglobin of cirrhotics at a cut off (13 mg/dl). The anemia in cirrhotics covariated significantly (p=0.05), with hypoalbuminemia, as revealed in Pearson’s coeffiecient of correlation (r=0.043).

Twenty lactic acid bacteria (LAB) were isolated from barley beer, six of these beer isolates were observed to secrete the inhibitory compounds into the cell-free filtrate with optimal production occurring in the late exponential growth phase. The inhibitory spectra of these isolates included various Gram’s positive and Gram’s negative bacteria and a variety of beer-spoiling bacteria. Based on standard biochemical and microbiological tests, these isolates were tentatively identified as Lactococcus lactis subsp. lactis, Lactobacillus sakei, Lactobacillus brevis, Lactobacillus plantarum, Lactobacillus pentosus, Lactobacillus paracasei. These inhibitory isolates were inactivated by treatment with proteolytic enzymes indication that the inhibitory compound was proteinaceous in nature, the proteinaceous nature and inactivation by catalase identified them as bacteriocins. These bacteriocins were partially characterized. Bacteriocins produced by these six isolates were active across a wide pH range, relatively insensitive to heat treatment. Stability of the secreted bacteriocins at varying pH values indicated that full activity was retained in all samples at pH 4-6 with a significant reduction in activity at pH 2-3 and pH 7-10.

Glasses having composition (60-x) B₂O₃-10Bi₂O₃-30Li₂O-xNd₂O₃ with x =1, 1.5 and 2 were prepared by melt quenching technique. The amorphous nature of the prepared glass samples was confirmed by X-ray diffraction. The absorption spectra of three Nd³⁺ lithium bismuth borate (LBB) glasses have been recorded at room temperature. From these spectral data various energy interaction parameters like Slater-Condon parameters F_k (k=2, 4 and 6), Lande’ parameters x_4f and Racah parameters E^k (k=2, 4 and 6) have been computed. Nephelauxetic ratio (β’) and bonding parameters (b^1/2) have also been computed from these parameters to study the nature of bonding in doped glasses. The intensities of the f-f transitions in the absorption spectra have been analyzed by the application of the Judd-Ofelt theory.

Different bacterial strains were isolated from hospitalized patients with Urinary Tract Infection and microscopically and biochemically characterized as Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus mirabilis Streptococcus sp., Staphylococcus saprophyticus and Alcaligenes   faecalis. Klebsiella pneumoniae was the most common urine isolate and Staphylococcus saprophyticus was another common organism. The antimicrobial activity of vitamin C sources like cranberry, amla, lemon, roseberry and mango was determined against a total of forty eight isolated organisms by well plate method and sensitivity of antibiotics were also checked by Kirby-Baur disc diffusion method. On comparative analysis of vitamin C source food articles and antibiotic sensitivity against isolated organisms it was found that action of cranberry, amla, lemon, roseberry and mango have good effect as compare to different antibiotics. Among these sources cranberry was most effective against all urine isolates. Due to the emergence of drug resistant microorganisms, it is a need to search out more effective antimicrobial agents to cure the disease. Our studies suggest that high intake of vitamin C tends to increase the acidity of urine which is not well tolerated by the bacteria responsible for UTI.

The aim of present study is to exist a novel super disintegrants in fast dissolving tablet. Guar gum is a natural substance and used in many pharmaceutical product and it can also used as a super disintegrating agent in fast dissolving tablet. The result is that it released the 99.21% drug in 15min as compared to Sodium Starch Glycolate (SSG), where only 97.51% drug was released. The onset of time was better for guar gum where, 84.79% of drug was released in 2min from F3 formulation as compared of F6 formulation where only 71.22% drug was released.  The possible mechanism of disintegrating property was good swelling property of guar gum than SSG but when the concentration of guar gum was used above 8%, it created a problem on disintegration of tablet due to formation of gel layer around the tablet. All evaluating parameters were within range and no markedly difference was observed.
