Abstract
The present work was to study the genetic variability between the major carps Labeo rohita and Cirrhinus mrigala and their hybrids of L. rohita (male♂) and C. mrigala (female♀). Genetic variability was studied by employing RAPD molecular markers. 25 samples of each target species having different sizes with the same age group for the determination of interspecific variation were collected. The morphometric parameters such as body weight, total length, tail length, and lengths of dorsal and anal fins of each individual were recorded and results showed that wet body weight, total length, dorsal fin, anal fin, and tail fin length are positively correlated and then the DNA was extracted using the inorganic salt-based method and conformed by Gel electrophoresis. Twenty-four arbitrary decamer primers were used to get species-specific RAPD analysis Distinct and highly reproducible RAPD profiles with significant genetic variability was detected among species. Only five primers showed amplification. The RAPAD primer OPB-05 produced a total of seven bands out of these 5 monomorphic and 2 polymorphic, so in this case, the percentage polymorphism was 28.57%. The Hybrid show more than a 50% difference from the Labeo rohita. This shows that the Hybrid more resembles C.mrigala. Phylogenetic analysis demonstrated that hybrid (L. rohita ♂ X Cirrhinus mrigala ♀) is the closest to C. mrigala and the farthest from L. rohita. Overall data are presented concerning the applications of RAPD markers for hybrid identification, genetic diversity assessment, and studying taxonomic relationships at a molecular level.

Abstract
In the present study we have monitored effects of repeated coadministration of fluoxetine with midazolam; a benzodiazepine (CNS depressant). It is the primary drug of choice for procedural sedation, preoperative sedation, and in emergency departments. Repeated administration of this drug is reported to have abuse potential and may cause this by increasing dopaminergic neurotransmission. Since an important role of serotonin is there in the pathophysiology of anxiety and addiction, administration of midazolam may involve altered 5-HT metabolism as well. Present study was designed to monitor effects of repeated administration of fluoxetine with midazolam. Effects of fluoxetine and midazolam coadministration were monitored on motor activities in familiar and novel environments, hot plate test, forced swim test, conditioned place preference test and levels of dopamine, 5-HT and their metabolites. Both midazolam (2.5mg/kg) and fluoxetine (1mg/kg) were administered orally for 12 days. Conditioned place preference test was performed on day 13. Rats were decapitated and whole brain samples were collected and stored at -70°C until neurochemical analysis by HPLC-EC. Findings from the present study show attenuation of midazolam-induced reinforcement upon repeated co-administration of fluoxetine. These could be implicated to increased therapeutic utility of midazolam and related benzodiazepines.

Abstract
Present study was designed to monitor the dose dependent effects of lorazepam; a benzodiazepine (CNS depressant). It is the primary drug of choice for treatment of anxiety and to produce calming effects. However, repeated administration of this lorazepam causes dependence and this might be caused by increased dopaminergic neurotransmission. Besides dopamine, 5-hydroxy tryptamine (5-HT) has also been reported to have pivotal role in the pathophysiology as well as treatment of anxiety and addiction. Repeated administration of lorazepam might involve altered 5-HT metabolism as well. Present study was therefore designed to monitor dose-dependent effects of lorazepam and to select its optimum dose for further experiments and pharmacological interventions. Effects of lorazepam were monitored on food intake, growth rate, activities in familiar and novel environments, light dark box activity, forced swim test and metabolism of dopamine and 5-HT. oral administration of lorazepam was done at the doses of 0mg/kg, 2mg/kg, 4mg/kg and 6mg/kg. Behaviors parameters were monitored following single administration of lorazepam. Rats were decapitated and whole brain samples were collected and stored at -70°C until neurochemical analysis by HPLC-EC. Findings from the present study could be implicated to increased therapeutic utility of lorazepam and related benzodiazepines.

Abstract
A new UV-Visible spectroscopic method assisted with microwave for the determination of glucose in pharmaceutical formulations was developed. In this study glucose solutions were oxidized by ammonium molybdate in the presence of microwave energy and reacted with aniline to produce a colored solution. Optimum conditions of the reaction including wavelength, temperature, and pH of the medium and relative concentration ratio of the reactants were investigated. It was found that the optimal wavelength for the reaction is 610 nm, the optimal reaction time is 80s, the optimal reaction temperature is 160°C, the optimal reaction pH is 4, and the optimal concentration ratio aniline/ammonium molybdate solution was found to be 1:1. The limits of detection and quantification of the method are 0.82 and 2.75 ppm for glucose solution, respectively. The use of microwaves improved the speed of the method while the use of aniline improved the sensitivity of the method by shifting the wavelength.

Abstract
The solubility, lability and fractionation of zinc in a range of calcareous soils from Peshawar, Pakistan were studied (18 topsoils and 18 subsoils). The lability (E-value) of Zn was assessed as the fraction isotopically exchangeable with (70)Zn(2+); comparative extractions included 0.005 M DTPA, 0.43 M HNO3 and a Tessier-style sequential extraction procedure (SEP). Because of the extremely low concentration of labile Zn the E-value was determined in soils suspended in 0.0001 M Na2-EDTA which provided reliable analytical conditions in which approximately 20% of the labile Zn was dissolved. On average, only 2.4% of soil Zn was isotopically exchangeable. This corresponded closely to Zn solubilised by extraction with 0.005 DTPA and by the carbonate extraction step (F1+F2) of the Tessier-style SEP. Crucially, although the majority of the soil CaCO3 was dissolved in F2 of the SEP, the DTPA dissolved only a very small proportion of the soil CaCO3. This suggests a superficial carbonate-bound form of labile Zn, accessible to extraction with DTPA and to isotopic exchange. Zinc solubility from soil suspended in 0.01 M Ca(NO3)2 (PCO2 controlled at 0.03) was measured over three days. Following solution speciation using WHAM(VII) two simple solubility models were parameterised: a pH dependent 'adsorption' model based on the labile (isotopically exchangeable) Zn distribution coefficient (Kd) and an apparent solubility product (Ks) for ZnCO3. The distribution coefficient showed no pH-dependence and the solubility model provided the best fit to the free ion activity (Zn(2+)) data, although the apparent value of log10 Ks (5.1) was 2.8 log units lower than that of the mineral smithsonite (ZnCO3).

Abstract
Peginterferon α-2a with ribavirin produces significantly higher sustained virological response (SVR) in comparison to conventional interferon monotherapy in patients with chronic hepatitis C virus (HCV) infection. We evaluated the efficacy and safety of peginterferon α-2a plus ribavirin combination in the treatment of chronic hepatitis C among Bangladeshi patients. A total of 64 patients were randomly selected in this study and were assigned for treatment with peginterferon α-2a 180μg once weekly plus ribavirin daily for 24 weeks in case of genotypes 2 and 3 infections and 48 weeks in case of genotypes 1 and 4 infections. Ribavirin was given 800mg in divided doses in case of genotypes 2 and 3 infections and 1000mg-1200 mg in case of genotypes 1 and 4 infections according to body weight daily(1000 mg in divided doses if body weight <75kg and 1200mg in divided doses if body weight >75kg). Efficacy was assessed by measurements of serum HCV-RNA and serum ALT. A higher proportion of patients (71.87%) who received peginterferon α-2a plus ribavirin had a sustained virological response. It is observed that genotype 3 (a and b) patients showed poor response (SVR-47.05%), where as genotypes 1(a,b), 3 and 4 mixed, 2b and 4 infections showed response rate of 100%. So it can be concluded that once weekly peginterferon α-2a plus daily ribavirin is effective in chronic HCV infection in Bangladesh and overall response rate is similar to that reported in other studies.

Abstract
The present study reports Gas chromatographic mass analysis (GC-MS) as well as important biological activities of Cymbopogon proximus essential oil. The chemical composition of the essential oil of Cymbopogon proximus was investigated by GC-MS. Furthermore, the effects of Cymbopogon proximus essential oil on the cardiac parasympathetic ganglia in rats, the intra-tracheal pressure in guinea-pigs and on carrageenan-induced inflammation in the rats paw, were studied. The GC-MS study led to the identification of 22 components with Piperitone representing (73.81%), Elemol (9.32%), alpha-Eudesmol (5.21%) and alpha-Terpineol (3.01%) of the oils composition. The percentage protective effect of the oil on the vagus-induced bradycardia in rats was 90.1±3.1%, which represents a significant protection. As for the effect of Cymbopogon oil on bronchoconstrictors-induced increase in intra-tracheal pressure in guinea-pigs, the oil antagonized the actions of 5-HT and histamine by 80±3.7 and 93±8.3%, respectively. Pharmacological investigations using Cymbopogon oil revealed its inherent ability to possess a bronchodilator activity mediated via blockade of both histamine and serotonin receptors. It possessed a significant ganglionic blocking action and a limited anti-inflammatory activity that seemed to involve blockade of histamine and serotonin receptors in the rats' paws.

Abstract
6-Nitrobenzimidazole derivatives (1-30) synthesized and their phosphodiesterase inhibitory activities determined. Out of thirty tested compounds, ten showed a varying degrees of phosphodiesterase inhibition with IC(50) values between 1.5±0.043 and 294.0±16.7 μM. Compounds 30 (IC(50)=1.5±0.043 μM), 1 (IC(50)=2.4±0.049 μM), 11 (IC(50)=5.7±0.113 μM), 13 (IC(50)=6.4±0.148 μM), 14 (IC(50)=10.5±0.51 μM), 9 (IC(50)=11.49±0.08 μM), 3 (IC(50)=63.1±1.48 μM), 10 (IC(50)=120.0±4.47 μM), and 6 (IC(50)=153.2±5.6 μM) showed excellent phosphodiesterase inhibitory activity, much superior to the standard EDTA (IC(50)=274±0.007 μM), and thus are potential molecules for the development of a new class of phosphodiesterase inhibitors. A structure-activity relationship is evaluated. All compounds are characterized by spectroscopic parameters.

Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) is a major complication of atrial septal defect (ASD) and can be responsible for significant functional limitations and early mortality. Various factors have been shown to predispose ASD patients to the development of PAH. Our study aimed to determine the association between the size of the ASD, the age of the patient and the increase in pulmonary artery pressures. METHODS Data from 74 ASD patients was retrospectively reviewed, including the patients' presenting symptoms, vital parameters, comorbidities, as well as their preoperative diagnostic workup. Echocardiography findings were used to determine the type and size of the ASD, and pulmonary artery pressures were evaluated using tricuspid regurgitation velocity as assessed by echocardiography or based on cardiac catheterization data. All patients underwent ASD repair either surgically or via percutaneous repair. Univariate and multivariate linear regression was performed to analyze the effect of age and defect size on pulmonary artery pressures. Model adequacy check was also done for the final model. Postoperative morbidity/mortality was additionally evaluated. RESULTS The study sample comprised 44.6% males and 55.4% females. The most prominent presenting features were shortness of breath (70.3%), chest pain (43.2%), and palpitations (33.8%), and arterial hypertension was the commonest morbidity. Using multiple linear regression analysis, age and size of ASD were found to be independently associated with pulmonary artery pressure. We found that for every 1 mm increase in the size of the ASD, pulmonary artery systolic pressure (PASP) increased by 0.32 mmHg ( P ≤ 0.05). Similarly, with every increase of one year in age, pulmonary artery pressure increased by 0.24 mmHg (P ≤ 0.02). No significant postoperative complications were reported following both types of repair. CONCLUSIONS Our study concludes that ASD patients are at greater risk of developing PAH with increasing age and increasing ASD size. This can potentially help to determine which ASD patients are at greater risk and require urgent repair of their defects. The study also shows that early repair is best to prevent complications.

Abstract
Polymorphisms of paraoxonase gene (PON) cluster have been investigated in numerous studies for their association with myocardial infarction (MI) but the results have been conflicting. Epistasis and gene-environment interactions at this locus could possibly modulate susceptibility toward MI and account for the discrepancies. We carried out a case-control study (211 MI patients and 370 control subjects) to test association of PON cluster polymorphisms with MI, their interactions with each other and with smoking. Genotyping was performed by PCR-restriction fragment length polymorphism based assays. The Q192R, C-108T, and A148G polymorphisms were associated with MI. Two haplotypes consisting of C-108T, C311S, and A148G, having allele frequencies of 0.17 and 0.14 in the control population, predisposed to MI (global haplotype statistic chi2 = 34.74, df = 15, p = 0.0027). Multifactor dimensionality reduction analysis showed a significant three-locus model (p = 0.02) involving these three polymorphisms, suggesting a potential gene-gene interaction between PON1 and PON2. These polymorphisms also interacted with smoking, in a three-locus and a four-locus model (p = 0.01 and p = 0.05, respectively). Additionally, the R192 allele may advance the age-at-onset of MI. The PON cluster appears to be a susceptibility locus for MI in Pakistani population, and the susceptibility is modulated through gene-gene and gene-environment interactions.

Abstract
10684 Background: Sequential use of docetaxel after four cycles of AC chemotherapy delays the postoperative radiation and can compromise loco-regional control. This delay can be avoided by starting radiotherapy concurrent with the docetaxel. We evaluated the feasibility of concurrent docetaxel and radiation therapy to chest wall and peripheral lymphatics after four cycles of AC chemotherapy. The preliminary results were reported in ASCO 2005 (Abstract 858). Methods: Females between 18–50 years, T2-T3 lesions, four or more positive nodes and hormone receptor negative tumors were eligible. Patients were enrolled after MRM. Four cycles of AC at 60/600 mg/m2 were followed by four cycles of docetaxel at 75mg/m2 every 21-days. Concurrent radiation to chest wall and peripheral lymphatics was started with the third cycle of docetaxel. A dose of 50 Gy in 5 weeks or equivalent was delivered. Successful completion of treatment in 18 out of 20 or 25 out of 30 patients was chosen as an index of feasibility. CTC version 2.0 of NCI and RTOG/EORTC Late Radiation Morbidity Scoring Scheme was used. Results: All the 30 enrolled patients successfully completed the planned treatment. Radiation was completed within 6 months of surgery in 27(90%) of the patients. Febrile neutropenia was seen in 5(16.7%). Grade-3 neutropenia and diarrhea in 8(26.7%) and 6(20%) respectively. Grade-3 dermatitis in the radiated area was seen in 2(6.7%) and grade-2 in 5(16.7%). Late toxicity included grade-2 skin atrophy and telangiectasia in radiated area in 6(20%) each. At a median follow up of 20 months (range 9–25 months) two local recurrences and two systemic relapses have been seen. Conclusion: This treatment schedule is feasible and safe in patients with high-risk operable breast cancer. It allows delivery of post mastectomy radiation within 6 months of surgery in patients undergoing sequential AC-docetaxel chemotherapy. No significant financial relationships to disclose.

Abstract
OBJECTIVE To find the prevalence of human intestinal pathogenic parasites. SETTING The study was conducted in Konkor, Gadap, District East, Karachi. METHODS After taking the verbal consent, all the villagers, selected by area sampling technique were interviewed by a structured questionnaire and then each person in the house was provided with a clean, plastic container to collect the stool samples. Samples were examined using normal saline, iodine preparation and zinc floatation technique where appropriate. RESULTS Out of 263 residents 185 tested for intestinal parasites and 88 (47.5%) had pathogenic parasites. The distributions of parasites were Giardia lamblia 50% and Entamoeba histolytica 48.86%. Statistically none of the socio-demographic variables were associated except education and age group. CONCLUSION In the light of the study result it is concluded that there is a high prevalence of parasitic infection in the community and an intervention strategy including health education program should be designed and implemented to control parasitic infections.
