ABSTRACT
This study was focused on The Determinants of Urolithiasis in Adults presenting to outdoor of Mayo Hospital, Lahore. Urolithiasis means stones in the urinary tract which may be of oxalate, phosphate or calcium. Objectives: To identify the frequency of various precipitating factors of urolithiasis and the percentage contributed by each factor in the disease. . Design: Sample study. Place: Lahore. Study Period: 2-3 months. Subjects and Methods: A sample was taken out of a 100 subjects having urinary tract stones presenting to Urology Outdoor, Mayo Hospital, Lahore. Selection methods were discussed to define the criteria for selection of the population. Patients were interviewed through questionnaires. Modern data collection, compilation and analysis techniques were adopted.After describing the demographic characteristics using frequency tables, pie charts and bar charts were prepared for illustration. Results: Out of 100 subjects, urolithiasis was found to be more in people above 35 yrs (64%), mostly common in women (54%) as compared to males (46%). Less water intake (in57% cases), unfiltered/ unboiled drinking water (in 82% cases), high intake of green vegetables/tomatoes (in 40% cases) and urinary tract infections (in 57% cases) were found to be significantly associated with urolithiasis, 69.5% of the males had pre existing Benign Prostate Hyperplasia. 24% of the cases were on diuretics when they developed urolithiasis. Contribution of commonly notorious risk factors like high calcium intake, high protein diet was not found to be significant. 23% of the individuals were taking high calcium supplements.4% of the individuals were on high protein diet. 25% of the individuals had pre existing hypertension. Only 21% of the individuals had co existing gouty arthritis. 13% had pre existing diabetes mellitus. None of them was on drugs like triamterene, indinavir, and sulfadiazine
ABSTRACT
Background: Psoriasis affects nearly 1% of the world population. It can be a source of significant morbidity and psychological stress to the patient but is not lethal under ordinary circumstances. Patients suffering from the disease feel a lack of empathy on part of care-givers, family members, healthcare professionals as well as society in general. Dermatology life quality index (DLQI) is a questionnaire-based assessment of health related quality of life in patients suffering from skin disorders and has been seen to correlate well with the impact of the disease on a patient. This study was done to understand the impact of psoriasis on the overall well-being of patients using DLQI as the tool of assessment.Methods: The study included 40 cases of psoriasis that were assessed for the severity of the disease based on percentage body surface area involvement. The impact of disease severity and other factors on the quality of life of the patient was assessed using DLQI.Results: Out of 35 patients with BSA involvement <50% (mild and moderate disease), 28.6% (n=10/35) showed a very large or extremely large effect on the quality of life while no patient with a BSA involvement >50% (severe and very severe disease) reported the same. A small, moderate or no effect on the DLQI was seen in 71.4% (n=25/35) of cases from the mild and moderate disease group while 100% (n=5/5) of cases from severe and very severe disease group reported a similar effect. Thus, DLQI was not directly related to the extent of BSA involvement and was dependent on other factors as well.Conclusion: Age had a correlation with the effect of the disease on the quality of life of psoriasis cases. Patients who were younger were more likely to report stress and anxiety related to the recurrences seen with the disease. Patients with lesions on sites that are socially exposed like face, hands, scalp, etc. were more likely to feel embarrassed about their condition. Younger age, female gender, lesions on exposed sites and recently diagnosed patients (<12 months) were factors which had a significant impact on the health-related quality of life of patients. The severity of disease and extent of involvement were not always directly related to extent of impact on the quality of life.
ABSTRACT
Abstract In the study presented here, a new series of 2-furyl(4-{4-[(substituted)sulfonyl]benzyl}-1-piperazinyl)methanone derivatives was targeted. The synthesis was initiated by the treatment of different secondary amines (1a-h) with 4-bromomethylbenzenesulfonyl chloride (2) to obtain various 1-{[4-(bromomethyl)phenyl]sulfonyl}amines (3a-h). 2-Furyl(1-piperazinyl)methanone (2-furoyl-1-piperazine; 4) was then dissolved in acetonitrile, with the addition of K2CO3, and the mixture was refluxed for activation. This activated molecule was further treated with equi-molar amounts of 3a-h to form targeted 2-furyl(4-{4-[(substituted)sulfonyl]benzyl}-1-piperazinyl)methanone derivatives (5a-h) in the same reaction set up. The structure confirmation of all the synthesized compounds was carried out by EI-MS, IR and 1H-NMR spectral analysis. The compounds showed good enzyme inhibitory activity. Compound 5h showed excellent inhibitory effect against acetyl- and butyrylcholinesterase with respective IC50 values of 2.91±0.001 and 4.35±0.004 µM, compared to eserine, a reference standard with IC50 values of 0.04±0.0001 and 0.85±0.001 µM, respectively, against these enzymes. All synthesized molecules were active against almost all Gram-positive and Gram-negative bacterial strains tested. The cytotoxicity of the molecules was also checked to determine their utility as possible therapeutic agents.

Glucose oxidase is an active oxygen species generating enzyme produced from Aspergillus niger grown in submerged fermentation. Disintegration of the mycelium resulted in high glucose oxidase activity that was subjected to ammonium sulfate precipitation at 60-85% saturation rates that resulted to 6.14 U mg -1 specific activity. Purification of enzyme by anion exchange column (DEAE-Cellulose) resulted into 22.53 U mg-1 specific activity and 10.27 fold purification. This was applied to sephadex G-200 column for gel filtration chromatography. It was observed that enzyme achieved 59.37 U mg-1of specific activity with 27.08 fold purity and 64.36% recovery. Purified glucose oxidase was injected into rabbits through intravenous route, to raise the glucose oxidase antibodies. After 30 days incubation period, the rabbits were slaughtered and serum was separated from blood. The antibodies were isolated by ammonium sulfate precipitation and confirmed by agar gel precipitation test. This could be a convenient and low cost alternate assay for the estimation of glucose oxidase in biological fluids. Moreover, such antibodies against the said enzyme could be used in various therapeutic and diagnostic applications.
