PHYSICOCHEMICAL STUDY OF A UNANI PHARMACOPOEAL TABLET ‘QURS-E-GULNAR’

In the Unani System of Medicine the drugs derived from natural sources are used, the majority of them are from plant origin. These single drugs are formulated in different dosage forms i.e. Tablets, Pills and Semisolids (Lauq, Khamira, Majoon etc.). Like any other system of medicine the efficacy of Unani formulations depends on potential and purity of the drugs used. To develop a mechanism for quality assurance of plants products and to ensure the purity of crude drugs and its standardization is essential. Standardization and quality control are the key factors in regulating the therapeutic efficacy because organoleptic parameters are insufficient for quality assessment. The present study deal with compound Unani formulation of Qurs-e-Gulnar a tablet formulated on the formullae mentioned in National Formulary of Unani Medicine Part I. For standardization of drugs, investigation of the tablets were made on the basis of the parameters approved by the Unani Pharmacopoea Committe, along with the analysis of pesticidal residue, microbial load, heavy metals and aflotoxin analysis. their percentage composition are as follow Total ash 22,89 %, Acid insoluble ash 21.72 %, Water soluble ash 1.39, Alcohol soluble matter 17.68 %, Water soluble matter 31.11%, , Water content 4.53%, pH 10%: 3.91 & 1%: 4.05, Disintegration time in pure water 30 second, Disintegration time in acid media 25 second, weight of qurs 500 mg and Diameter of qurs 10 mm is being determined and purity is confirmed. In addition analysis of Microbial Load, Aflatoxin and Pesticidal residue were also done but not detected The Thin layer chromatography (TLC) finger printing was made to check the standard of future batch

Role of rhubarb and α-keto analogues of essential amino acids supplementation in halting progression of chronic kidney disease

Background: Chronic kidney disease (CKD) is an emerging chronic disease due to rapidly increasing incidence of diabetes and hypertension worldwide. Newer drugs are being searched which can stop nephron damage and are cost effective. This study was undertaken to compare the efficacy and safety profile of rhubarb and α-keto analogues of essential amino acids supplementation in patients of chronic kidney disease.Methods: A prospective comparative study was conducted in patients of chronic kidney disease attending Renal Clinic of a tertiary care centre. Randomization of patients was done into three interventional groups: conservative management along with placebo was given in first group (Control); conservative management along with Rhubarb capsule (350 mg, thrice daily) was given in second group (Rhubarb) and conservative management along with α-keto analogues of essential amino acids (600 mg, thrice daily) was given in third group (KAA). The treatment was given for 12 weeks. Clinical and biochemical parameters were assessed at 0, 4, 8 and 12 weeks of treatment.Results: Patients of all three groups showed gradual improvement in clinical features and biochemical parameters as compared to their pre-treated values which was more marked in KAA supplemented group. There was reduction in: fasting blood glucose (12.51%, 19.15% and 20.78%), PPBG (14.80%, 19.00% and 20.89%), serum creatinine (25.00%, 30.54% and 39.52%), blood urea (25.55%, 33.64% and 38.09%), and 24-hour total urine protein (TUP) (19.80%, 30.18% and 38.34%) in Group I, II and III respectively. There was increase in: haemoglobin level (12.64%, 14.99% and 19.77%), 24-hour total urine volume (TUV) (19.41%, 28.82% and 33.32%) and GFR (22.6%, 46.5% and 49.2%) in Group I, II and III respectively. Rhubarb and KAA supplementations were safe and well-tolerated.Conclusions: KAA is more effective than Rhubarb as add on therapy with conservative management in patients of chronic kidney disease

Protective effect of Nigella sativa against paracetamol induced hepatic and renal damages

Background: Non-steroidal anti-inflammatory drugs are very commonly used as an analgesic, antipyretic, anti-inflammatory, and antiplatelet agent. They have significant adverse effect on liver and kidney besides damaging stomach. Their effect on liver and kidney are of serious concern. Hence, we have decided to study the preventive effect of Nigella sativa against paracetamol induced hepatic and renal damages.Methods: Ethanolic and aqueous extracts of N. sativa were prepared with the help of Soxhlet’s apparatus. Totally, 36 wistar albino rats (150-200 g) of either sex were divided into six groups of six each. Group I was administered with distilled water, Group II-VI were treated with paracetamol 750 mg/kg i.p. Group III-VI were test groups also treated with N. sativa aqueous extract (200 and 400 mg/kg p.o) and ethanolic extract (200 and 400 mg/kg p.o), respectively. The treatment was given daily for 7 days and on 8th all the rats were sacrificed and the blood was analyzed for hepatic and renal function tests and tissue was preserved for histopathological examination.Results: Paracetamol administration caused a marked hepatic and renal damage, which is evidenced by the increase in liver and renal function test parameters in the negative control group. N.sativa extracts prevented this damage. The protective was seen maximum in ethanolic extract followed by the aqueous extract in dose-dependent manner.Conclusion: Ethanolic extract showed significant protection against paracetamol-induced and renal damage

There was no significant difference in two groups with respect to side effects (p>0.05).Conclusions: It is concluded in Patients of mild Bronchial Asthma Theophylline and doxofylline improve the spirometric and clinical symptoms and doxofylline has no advantage over theophylline in terms of either efficacy or safety on the doses commonly used in current clinical practice

Solution equilibria of the i-motif-forming region upstream of the B-cell lymphoma-2 P1 promoter

11 pages, 8 figures.-- PMID: 17850948 [PubMed].-- Printed version published Dec 2007.The 5'-end of the P1 promoter of the B-cell lymphoma-2 (bcl-2) gene contains a highly guaninecytosine-rich region, which has a role in the regulation of bcl-2 transcription. Whereas the guanine-rich region has been the focus of recent studies, little attention has been paid to the cytosine-rich strand. Here we examine the structural transitions of the cytosine-rich sequence by means of acidebase, mole-ratio and melting experiments monitored by molecular absorption, circular dichroism, and NMR spectroscopies. Two intramolecular i-motif structures have been detected in the pH range 2-7, with maximal formation at pH 4 and 6, respectively. At pH 7.6 the majority species has been associated with a hairpin involving Watson-Crick base pairs. Upon addition of the quadruplex-interacting ligand TmPyP4, bcl-2c structures at pH 6.1 and 7.6 yield identical interaction species with stoichiometries 1:2 (DNA:ligand) and logarithms of formation constant 12.4 ± 0.2 and 11.7 ± 0.1, respectively. The initial i-motif structure at pH 6.1 is lost upon interaction with TmPyP4.We acknowledge two grants from the Spanish Ministerio de Educación y Ciencia (projects BFU2004-02048/BMC and CTQ2006-15052-C02-01/BQU).

Urbanization growth dynamic model of metropolitan city Karachi

The city Karachi has grown from a small fishing village to the enormous metropolis and now becomes the biggest and most industrialized city of Pakistan due to its multi-ethnic character. It population now exceeds 12 million (approximately) and its current growing rate is about 5% per year. This phenomenal, growth of the metropolitan city affects nomads as well as high class society and covers almost all aspect of life such as social, economical, political, sociological, psychological etc. This unchecked increase becomes the origin of the problems of slums, katchi abaadis, and encroachment. It has been estimated that one-third of the total population resides in squatter settlements and slums which results in chronic shortage of dwelling units, water supply, public transport, and civic amenities such as schools, hospitals , parks and playgrounds. This rapid growth of population is a burning issue for developing and governmental agencies. In this study attempts has been made to provide a systematic analysis of the population growth in the metropolitan city Karachi and model have been constructed by using the available demographic data. Finding of this model will serve as a basis for making planning to control rate of population growth in both Urban and Rural areas and develop a strategy to attain higher level of structural change of urbanization
