ABSTRACT

Hypertensive crises is still a major public health problem, causing end organ damage like myocardial infarction, stroke, and renal failure. Labetalol and nitroglycerine are among the two most commonly used medicine to control the blood pressure, but there is no head to head comparison between these two medicines. This was a prospective randomized non-blinded study which included 50 patients of hypertensive crises, out which 25 patients received intravenous labetalol and 25 patients received intravenous nitroglycerine. We found that labetalol controlled the blood pressure more rapidly in comparison to nitroglycerine, without causing any extra side effect

ABSTRACT

Abstract The present study was designed to evaluate the beneficial synergistic effects of S-allyl Cysteine (SAC) and Taurine (TAU) on hyperglycemia, lipid profile and renal damage markers in type 2 diabetes mellitus (T2DM) in rats. Experimental T2DM was developed by administering an intraperitoneal single dose of nicotinamide (NA; 230 mg/kg) and streptozotocin (STZ; 65 mg/ kg) in adult rats. Control and diabetic rats were treated with SAC (150 mg/kg); TAU (200 mg/ kg) or SAC and TAU (75+100 mg/kg) combination for four weeks. Measurements of traditional markers of kidney toxicity in serum, such as blood urea nitrogen (BUN), serum creatinine (Scr), and alkaline phosphatase (ALP), together with serum cholesterol/triglyceride such as serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and very low-density lipoprotein cholesterol (VLDL-C) may yield a snapshot of renal damage and lipid profile in NA/STZ-treated rats. The variation in levels of fasting blood glucose, glycosylated hemoglobin, insulin and lipid profile was significantly augmented in SAC/TAU treatment group. The diabetic group showed elevated renal injury markers in serum, which were decreased significantly by SAC/TAU treatment. Thus the results of the experiment clearly indicate the potential of the SAC/TAU combination in improving diabetic complications.

ABSTRACT

This review present Gingko biloba (GB) interactions, based on clinical and pre-clinical presentations. Literature was retrieved using databases; ScienceDirect, PubMed, Google scholar, Web of Science, Scopus etc. 14/45 interactions were found with clinical presentations. More interactions (80%) were reported with drugs followed by herbs (11.1%), and nutraceuticals (6.7%) with major mechanisms of interaction observed as; inhibition of Cytochrome metabolizing enzymes (44.4%) and platelet-activating factor (PAF) i.e. 15.6%. Major clinical features were; increased bleeding (eye, parietal), hematomas (subdural), and seizures as well as increased blood pressure, priapism, loss of infection/antiviral failure, and coma. Drugs with major interactions belonged to anti-platelet/anti-coagulant and NSAIDs. Synergistic effects were observed for GB vs herbs (except cannabis which showed rhabdomyolysis), foods, and nutraceuticals (except pyridoxine where neurotoxicity was seen). GB use should be monitored and the patient may seek proper advice from a healthcare professional.

ABSTRACT

Background: Homeopathy, as an alternative treatment system for the treatment of various diseases, is widely used in various regions of the world. However the clinical benefits of homeopathy remains controversial. Aim of the Study: This review highlights the most up-to-date and current clinical trials and research carried out in the field of homeopathy and to compare its effectiveness in combating various diseases. Methodology: A retrospective literature search was performed from 2012 to 2017. All the articles, containing clinical trials in human subjects, were searched in different databases such as google scholar, science direct, web of science, Scopus, Springer Link and Sci Finder etc. using the keywords i.e. clinical trials in homeopathy, current clinical status of homeopathy, homeopathy and treatment of diseases, clinical cases in homeopathy and clinical studies in homeopathy. Results: Twenty one articles met the inclusion criteria and were included in this review. The results of these clinical studies showed an effective outcome for homeopathy treatment in various diseases such as atopic dermatitis, eczema, respiratory tract infections, asthma, hay fever and pulmonary tuberculosis etc. However, for some of the diseases such as depression, mental fatigue, cancer, HIV, anxiety, dementia, induction of labor, osteoarthritis, migraine and insomnia etc. no proper clinical evidence for a safe and effective use of homeopathy exists.  Furthermore, the research quality of most the homeopathy clinical trials are objectionable and negatively analyzed by various authors in terms of sample size, reproducibility and replication of data as well as lack of proper guidelines for performing homeopathy research. Conclusion: To build credibility in health care system and attract more patients as well as professional practitioners towards this system of alternative treatment, more focus in terms of quality research and practically applicable clinical trials i.e. efficacy trials (near to optimal laboratory conditions) is needed.

ABSTRACT

Objective: To search for the most active antimicrobial and antioxidant sub-fractions related to traditional use of Ziziphus oxyphylla (Z. oxyphylla) and Cedrela serrata (C. serrata) in Pakistan against infectious and liver diseases. Methods: Factions of different polarity were tested in vitro for their antiprotozoal, antimalarial, antibacterial and antifungal activity against different pathogens. Cytotoxicity on MRC-5 cell lines (human lung fibroblasts) as well as, in vitro radical scavenging activity was evaluated using the 1, 1-diphenyl-2-picrylhydrazyl radical assay. Results: The highest antiprotozoal activity was observed for the CHCl3 fractions of Z. oxyphylla roots and leaves, and C. serrata bark. The CHCl3 and EtOAc fractions of Z. oxyphylla roots, the CHCl3 fraction of Z. oxyphylla leaves, the EtOAc and the residual MeOH: H2O fraction of C. serrata bark showed antibacterial activity against Staphylo-coccus aureus. The same residual MeOH: H2O fraction of C. serrata bark was active against Candida albicans. The highest antioxidant activity was observed for the more hydrophilic EtOAc fractions of Z. oxyphylla leaves, C. serrata bark and leaves, and the residual MeOH:H2O fraction of C. serrata bark. Conclusions: This study supports at least in part the traditional uses of these plants for antimicrobial purposes and against liver diseases.

ABSTRACT

Objective of the present study was to carry out the physicochemical and phytochemicals standardization of Lepidium sativum Lseeds to establish the standard pharmacognostical parameters of this valuable medicinal plant. Many standardization parameters of Lepidium sativum were analyzed. Standard method was adopted for the preliminary phytochemicals screening. Analysis of pesticides residues, aflatoxin & heavy metals were also performed. The sections of seeds were prepared for quantitative microscopic parameters. The air dried powdered plant material was subjected for determination of physicochemical standardizations like ash value, Extractive value and fluorescence nature of the powder drug using light of short and longwavelength of 254nm and 366nm respectively. Phytochemical screening was performed for the identification of phytoconstituents in the plant which was helpful in the development of analytical profile. The morphological and microscopic examinations of drug were revealed the presence of endosperm cell which are polygonal in shape and contain alerone grains and oil droplet, cell of testa, yellow colouring matter and starch grains. Preliminary phytochemical screening showed the presence of carbohydrates, phenolic compounds, flavonoids, alkaloids, proteins, saponins and lipids in the drug extract and flourescence nature of drug was confirmed by fluorescence analysis in different solvent. Concentrations of heavy metals,ash value and extractive value were determined and found within acceptable Pharmacopoeial limits. Pesticides residues and aflatoxins were also determined but not detected in the tested samples. The physicochemical and phytochemical standards which are outcome of this research may be utilized as substantial data for identification and standardization of L. sativum seed.

ABSTRACT

Aims: To determine the antioxidant, antiglycation and antibacterial activity of two selected plants found wild in Pakistan (Ziziphus oxyphylla and Cedrela serrata). Study Design: In vitro assessment of antioxidant assays, phenolic and flavonoid content, protein-glycation inhibition and antibacterial study. Place and Duration of Study: Department of Pharmaceutical Sciences, University of Antwerp Belgium (February - April 2013; Antioxidant, Protein glycation). Department of Pharmacognosy, University of Karachi, Pakistan (March – June, 2012; antibacterial). Methodology: In vitro laboratory experimental tests; preparation of plant extracts, antioxidant assays (ABTS.+, PMS-NADH radicals), total phenol, total flavonoid; protein glycation (fluorescence); susceptibility tests (zones of inhibition). Results: The bark of C. serrata contained the highest amount of total phenol (0.35 ± 0.04 mg GAE/g extract) and exhibited significantly superior ABTS.+ and PMS superoxide radical scavenging activity with IC50 values of 0.043 ± 0.001 mg/ml and 0.18 ± 0.01 mg/ml, respectively (P=0.05). Similarly, the protein-glycation assay revealed that the bark of C. serrata had the best inhibitory property with a low IC50 value of 0.61 ± 0.02 mg/ml (P=0.05), probably due to the presence of high amounts of total phenol. Furthermore, the various extracts showed considerable inhibition against both Gram–positive and – negative bacterial growth when compared against two standard drugs neomycin and doxycycline. Conclusion: The results of this study substantiate a probable role for these plants to be utilized as a natural source of antioxidant having a wide range of bioactivities.
