Abstract: Objectives: To find out the efficacy and safety of Levofloxacinin patients suffering from typhoid fever. Design: Non-comparative and prospective study. Setting: Medical Units ofAllied & DHQ Hospital (PMC) Faisalabad. Period: From May 2002 to July 2004. Material & Methods: All suspectedfebrile patients were examined and provisionally diagnosed to have typhoid fever were admitted for the purpose ofstudy till they were satisfactorily discharged. Results: This clinical study was conducted on 70 patients of Enteric Fever.Fifty-two patients were male and 18 were female. The mean age for male patients in the study sample was 37.58± 8.13while the mean age of females was 21.92± 4.73 years. Fever as a symptom was present in all 70(100%) of thepatients. Anorexia was there in 61(85.5%)patients and abdominal pain in 49(70%) patients. Twenty-seven (38.5%)patients had constipation along with other features. Diarrhea was present in 6 (8.5%) patients. Relative bradycardiawas present in 20(28.5%) patients. Hepatomegaly was there in 31(44.3%) and Splenomegaly in 24(34.3%). Elevatedliver enzymes were found in 29 (41.4%) of the patients and blood cultures positive for Salmonella typhi was seen in19(27.1%) patients. Widal test was positive at dilution of 1:160 in almost all of the cases and at 1:320 dilution in 18%of cases in current study. The success rate of Levofloxacin in our study was 100% in the form of settlement of feverand other symptoms and signs. The side effects were seen in 17(24.2%) patients. Conclusions: In conclusionlevofloxacin is effective in treatment of typhoid fever and its use in this indication is safe.
ESOPHAGEAL VARICES
MAQSOOD AHMAD
The Professional Medical Journal , 2007,
Abstract: A comparative trial was conducted to study the relative efficacy ofendoscopic injection sclerotherapy versus endoscopic injection sclerotherapy plus octreotide with reference to acutecontrol of bleeding esophageal varices and early re-bleeding. A total of 58 patients equally divided in two groups wereincluded in this study. Bleeding was controlled in 90% patients in both the groups. In group1 there were 20(68.96%)males and18(62%) males in group 2. The mean age of the patients under study was 50.62 &50.55 in group 1& 2respectively. The major proportion of patients was in Child Class B, which comprised of 42(72.41%) in total. ChildClass C was excluded out of study. Twenty-two (75.86%) patients in group 1 were in Child Class B and 7(24%) werein Child Class A & in group 2 there were 20 (68.96%) patients in Child Class B and 21% were in Class A. Etiology ofcirrhosis was HCV in 41(70.86%) and HBV in 9(15.5%) and other etiologies in remaining patients. In, group 1,HCVrelated cirrhosis was seen in 20 (68.96%) and in group 2, this was responsible for cirrhosis in 21(70.68%) of patients.Patients suffering from HBV related cirrhosis were 5(17.42%) in first group and 4(13.79%) in second group 2. Relativelyless number of patients in group 2, had rebleeding in first week of their in-hospital follow-up i.e. 5 versus 8 patients.Average number of blood transfusions per patient was 3.86 piants in group 1and 2.45 piants in group 2. The meanduration of Hospital stay was 8.52 days in group 1 and 7.45 days in group 2. Procedure related complications and inhospital outcome was almost comparable in two groups. The most common complication was hepatic encephalopathy.Combining endoscopic therapy with one of the vasoactive agents reduces the chances of early re-bleeding and needfor number of blood transfusions and duration of hospital stay.

Ehtesham Ghani, Ayman AlBanyan, Abdulrahman Sabbagh, Maqsood Ahmad
Open Journal of Pediatrics (OJPed) , 2017, DOI: 10.4236/ojped.2017.72012
Abstract: Objective: Aim of the study was to assess the duration of preoperative external ventricular drain (EVD) as a predictor for permanent cerebrospinal fluid (CSF) diversion in pediatric posterior fossa tumors. Methods: The study was conducted in the Department of Pediatric Neurosurgery, National Neuroscience Institute, King Fahad Medical City, Riyadh, Saudi Arabia from January 2010 to December 2013. The data were collected retrospectively. The patients who had emergency insertion of external ventricular drain (EVD) due to hydrocephalus before the definitive posterior fossa tumor surgery were included in the study. Results: The preoperative emergency insertion of EVD was done in 38 patients with pediatric posterior fossa tumors. The patients were divided into two groups. Group A consists of those patients who had duration of preoperative EVD equal or less than 7 days. Group B includes those patients who had duration of preoperative EVD more than 7 days. Group A has 16 patients while Group B has 22 patients. The predominant clinical feature was symptoms and signs of raised intracranial pressure (ICP) only. Infection related to EVD was seen in seven patients. Ventriculoperitoneal (VP) shunt was required in 31.25% of Group A patients and 18.18% of Group B patients (p value = 0.35). Overall shunt rate was 23.68%. Conclusion: There are well known number of factors that can determine the need of permanent CSF diversion in patients with posterior fossa tumors. However, there is no effect of preoperative duration of EVD in determining the requirement of postoperative VP shunt.

Advances in Alzheimer's Disease (AAD) , 2018, DOI: 10.4236/aad.2018.72005
Abstract: Ficus infectoria has a wide distribution in Bangladesh, Nepal, Pakistan, Sri Lanka, Southwest China and Indochina and is an enrich source of phytochemicals thereby possess antibacterial, antifungal and hyperglycaemic activities. In this study, we attempted to examine the cognitive ability of methanolic and ethanolic extract of F. infectoria fruit extract in scopolamine induced memory impairment in mice by using preliminary phytochemical and antioxidant tests, and the cognitive ability of the methanolic and ethanolic fruit extract of F. infectoria. Fruit extract was analyzed in scopolamine amnesia mice using passive avoidance approach. Piracetam was used as a reference drug (200 mg/Kg). Further confirmation was provided by means of mice brain homogenate biochemical tests. Maximum phytochemical, antioxidant activity and nootropic ability were observed in the ethanolic fruit extract of F. infectoria. Plant extract was used at three doses i.e. 75 mg/Kg, 150 mg/Kg and 300 mg/Kg and exhibited nootropic abilities in all tests used. Enhanced SDL value i.e. (291.2 ± 0.33+++###) was observed by the administration of plant extract at all dose range in comparison to reference drug i.e. piracetam (252.8 ± 1.60###) used in the study. The plant extract utilization has showed increase in total protein (25.08 ± 0.26+++### mg/g of tissue) and reduced glutathione content (33.0 ± 0.46+++### nmoles/mg of protein) and vice versa while low malondialehyde (MDA) (9.18 ± 0.17+++### nmoles/mg of protein) and AChE activity (0.067 ± 0.009+++### M/min/g protein). However, opposite situation was observed in the scopolamine amnesia mice. Hence it was concluded the plant extract possessed neuroprotective activity in the scopolamine induced cognitive decline in mice thereby used as cost effective natural medicines in near future.

Silver Nanoparticles: Green Route, Stability and Effect of Additives  [PDF]
Zaheer Khan, Javed Ijaz Hussain, Sunil Kumar, Athar Adil Hashmi, Maqsood Ahmad Malik
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2011, DOI: 10.4236/jbnb.2011.24048
Abstract: Colloidal silver nanoparticles were prepared by reducing silver nitrate with oxalic acid in presence of cetyltrimethylammonium bromide (CTAB). The synthesized silver particles show an intense surface plasmon band in the visible region. The work reported in this paper describes the effect of concentration of various additives (NaCl, NaBr, NaNO3, Na2SO4 and NaH2PO4) and ammonia on the growth and stability of Ag-nanoparticles. In all the cases the rate decreases as the [electrolytes] or [ammonia] increases. The nature, polarizability and coordinating ability of the anions play vital roles for nucleus formation and the growth process, which subsequently form different size particles. Transmission electron microscopy, selected areas electron diffraction, and UV-visible spectroscopy have been employed to characterize Ag-nanoparticles. The effect of the following variables on the particle size and size distribution was investigated: the [oxalic acid], [CTAB] and [Ag+].The nanoparticles are stable in NaNO3 and NaH2PO4 solutions; but NaCl, NaBr and Na2SO4 causes their aggregation.

Zafar Iqbal, Muhammad Maqsood Tahir, Naureen Riaz, Syed Azeem Ali, Munir Ahmad
Open Journal of Statistics (OJS) , 2017, DOI: 10.4236/ojs.2017.74045
Abstract:
The techniques to find appropriate new models for data sets are very popular nowadays among the researchers of this area where existed models in the literature are not suitable. In this paper, a new distribution, generalized inverted Kumaraswamy (GIKum) distribution is introduced. The main aims of this research are to develop a general form of inverted Kumaraswamy (IKum) distribution which is flexible than the IKum distribution and all of its related and sub models. Some properties of GIKum distribution such as measures of central tendency and dispersion, models of stress-strength, limiting distributions, characterization of GIKum distribution and related probability distributions through some specific transformations are derived. The mathematical expressions of reliability function (r.f) and the hazard rate function (hrf) of the GIKum distribution are found and presented through their graphs. The parameters estimation through the maximum likelihood (ML) estimation method is used and the results are applied to the data set of prices of wooden toys of 31 children.

Zaheer Ahmad,Maqsood Ahmad Gill,Abdul Matin Shah,Tahir Mahmood
Pakistan Journal of Biological Sciences , 1998,
Abstract: Seven cotton (Gossypim hirsutum L.) varieties were evaluated for growth and utilization efficiency of nitrogen (N) and phosphorus (P), in hydroponics using modified Johnson s solutions containing adequate (6.0 mM N and 0.20 mM P), and deficient levels of N (0.8 mM) and P (0.01 mM). Substantial differences were observed among varieties for accumulation of shoot dry weight (SDW), relative reduction in shoot biomass due to N-deficiency (NSF), and uptake by shoot in case of N, and root dry weight (RDW), root:shoot ratio (RSR), relative reduction in shoot biomass due to P-deficiency (PSF), concentration in shoot and uptake by shoot in case of P. Variety SLS-1 exhibited the minimum stress at N-deficiency (NSF = 34%) as well as P-deficiency (PSF=59%) among all the varieties. A negative correlation (r=0.555, n=35) between SDW and RSR in P-stressed plants suggested increase RDW production at the cost SDW. Utilization efficiency in varieties remained unchanged in case of N-deficiency stress and decreased in case of P-deficiency stress as compared to control, and in both the cases differences among varieties remained statistically non-significant. Nutrient level X variety interaction was significant for all the parameters studied in case of P, whereas for N, the interaction was significant only for shoot dry weight, stress factor and uptake by shoot.
Intra-Specific Variations of Phosphorus Utilization Efficiency
Zaheer Ahmad,Muhammad Aslam,Maqsood Ahmad Gill,Muhammad Yaseen
Pakistan Journal of Biological Sciences , 2000,
Abstract: Soils of Pakistan are frequently characterized as deficient in plant-available phosphorus (P). The option of fertilizer applications to cope the situation has proved cost-intensive for resource-poor farmers of the country. Under the circumstances, exploitation of genetic variations in crops for P-use efficiency and identification of P-efficient crop cultivars hold great promise. Experiments conducted at the University of Agriculture, Faisalabad indicated significant growth differences among varieties of wheat, rice, chickpea and cotton when grown under P-deficient as well as P-adequate conditions. Differences in relative adaptability of varieties to P-deficiency stress were also considerable. In this paper, work done in Pakistan and elsewhere on genotypic variations of P-nutrition of crops is briefly reviewed. Various physiological mechanisms responsible for such variations are also discussed.
