  Biodisposition of drug was investigated in male volunteers following the oral dose of 250mg. Blood samples were collected after predetermined schedule and drug concentration was determined by microbiological assay. The two compartment model kinetics analysis of plasma clarithromycin concentration versus time data revealed that the average ± SD values of t1/2ß, clearance and volume of distribution are 1.36±0.14h, 20.43±3.04 l/h and 39.91±1.461 l/kg respectively. The absorption rate constant, area under curve (AUC) and mean resident time with ± SD are 0.51±0.05h, 12.36±1.43 h.mg/l and 4.17±43 h respectively.

  Topping stages and levels had a significant effect on the chemical composition of flue-cured virginia. Plants topped at button stage produced desirable chemical characteristics as indicated by their moderately high total nitrogen (2.06%), highest nicotine (2.07%) and potash (2.70%) contents and lowest chloride (2.71%) and reducing sugar (11.72%) contents. Plants topped at 16 leaves level also produced desirable chemical characteristics, having lowest total nitrogen (1.95%), chloride (2.73%) and reducing sugar (11.72%) contents and highest nicotine (1.98%) and potash (2.67%) contents respectively. Topping beyond button stage and above 16 leaves level resulted in undesirable chemical characteristics.

  The increase in levels of NPK increased days to flowering and maturity, plant height, head diameter and number of grains per disc. However, the increase in 1000 grain weight and grain yield per hectare was upto 80:50:50 kg/ha NPK level after which it dropped. On the basis of these findings, application of 80:50:50 kg NPK/ha is recommended for sunflower crop to obtain maximum grain yield under irrigated conditions.

  In the current exploration, sweet liquid whey was subjected to physicochemical analysis, minerals assay and amino acid profiling. It comprised of total solids, lactose, ash, crude protein and fat as 6.49±0.31, 5.26±0.26, 0.56±0.02, 0.81±0.03 and 0.25±0.01%, respectively. The results regarding mineral analysis indicated that whey contains appreciable amount of potassium, sodium and calcium. Furthermore, amino acid profile elucidated it a balance source of essential and non-essential amino acids. Amongst essential amino acids, highest value was noticed for leucine 97.25±4.68 followed by lysine and threonine 83.98±2.46 and 48.89±2.84 mg/g protein.

  The present investigation was an effort to explore the nutritional profile and antioxidant indices of vitamin K dietary sources i.e., spinach and soybean. For the purpose, spinach and soybean were nutritionally characterized with special reference to vitamin K content. The proximate composition of spinach exhibited that moisture, crude protein, crude fat, crude fiber, ash and Nitrogen Free Extract (NFE) as 90.71±4.14, 2.03±0.95, 0.32±0.007, 0.58±0.02, 1.24±0.06 and 5.01±0.11%, respectively. However, tested soybean indicated the values respective traits as 8.96±0.45, 32.28±1.99, 18.64±1.02, 2.93±0.16, 3.38±0.19 and 33.79±1.15%. Furthermore, spinach showed good mineral profile dominated by magnesium, potassium and calcium whilst soybean is abundant in potassium, zinc and magnesium. The HPLC quantification of vitamin K revealed that spinach contained 379.09 μg/100g phylloquinone as compared to soybean 29.79 μg/100g. Amongst antioxidant extracts, methanolic extracts of spinach and soybean showed higher total phenolic, DPPH scavenging and antioxidant activities. In conclusion, spinach showed higher antioxidant status and phylloquinone as compared to soybean however, soybean contained ample amount of protein and fat contents.

  Background and Objective: Purple blotch caused by A. porri (Ellis) Cif. is a devastating disease of onion (Allium cepa L., 2n =16) throughout the world. This study compared effectiveness of the most frequently used fungicides and different plant extracts as control measures for the purple blotch disease. Materials and Methods: The fungal inhibition potential of leaf extracts was evaluated from 7 plants, indigenous to District Swat as well as the commonly available fungicides under laboratory conditions. Multivariate analysis and the ANOVA results revealed a direct relationship for the plant extracts/fungicides application and mycelial inhibition. Results: The extracts of C. sativa (1 and 2 ppm) was found the most effective and caused over 91.89 and 91.66% inhibition of mycelial growth. The order of efficacy of the 1 ppm plant extract was followed by D. mucronata (79.00%), D. viscosa (78.99%), C. procera (77%), J. adhatoda (60.65%) and A. altissima (57.98%), while in 2 ppm 83.14% was followed by 82.09, 82.02, 71.33, 55.05 and 39.32%, respectively. Among the 5 fungicides applied, DuPontTM Curzate® M8 in both concentrations were the most effective and caused over 89.88% inhibition. Potential synergy of the of leaf extracts of C. sativa+J. adhatoda was highly effective, resulted in 80 and 84.28% mycelial inhibition. Conclusion: The results highlight the critical role of finding the right proportion of appropriate compounds to perform as a potential pesticide. These results indicate to the importance of phyto extracts as promising alternatives to synthetic fungicides for being cost effective, eco-friendly and sustainable means of controlling the purple blotch of onion.
