غزل۔۔۔ڈاکٹرالیاس عاجز
مری آہ و فُغاں سُن کر خفا دربار ہیں مُجھ پر
مَیں باغی ہوں مگر پہلے بغاوت کا سبب جانو
اِدھر بے زار ہوں مَیں حاشیہ بردار ٹولے سے
اگر حکمِ اطاعت ہے تو پھر یہ یاد رکھ لینا
سُبُک سر لوگ بستی کے مرا اب خوں بہاٸیں گے
اسیری میں حُرِیَّت کی فضا میں خود بناٶں گا
مَیں بیعت کر تو سکتا ہوں مگر پھر جھوٹ پر مبنی
مرے لفظوں میں رنج و غم سمٹ آتا ہے اُمَّت کا
نہ سمجھو کھیل لفظوں کا یہ دل کو چیر نکلے ہیں
یہ لکھتے اُن کی جانب سے کٸی اخبار ہیں مُجھ پر
وگرنہ ہتھکنڈے اوچھے سبھی بے کار ہیں مجھ پر
اُدھر ظِلِّ اِلٰہی بھی بڑے قہار ہیں مُجھ پر
حُسینی ہوں کٸی واجب ابھی انکار ہیں مجھ پر
کہ کھینچے شش جِہَت سے تیر اور تلوار ہیں مجھ پر
فلک تک پھر اُٹھاٸے جو دَر و دیوار ہیں مُجھ پر
قصیدے شاہ کے لکھنا بڑے دُشوار ہیں مجھ پر
کہ ماضی حال و مستقبل سبھی بیدار ہیں مجھ پر
وَرُودِ جسم و جاں عاجز جو بھی اشعار ہیں مجھ پر
Congenital Heart Defect (CHD) is a multifactorial disorder based on both genetic and environmental factors involved in development. The basic problem lies in the structure of heart leading to CHD that occurs in walls, valves, arteries and veins of heart. During cell cycle, the gene that controls this process may mutate, causing disturbance in any portion of heart leading to disturbed blood flow, blood flow in wrong direction or complete blockage. Defect may range from simple with no manifestations to complex with severe symptoms. Simple defects need no treatment while some babies with complex birth defects during birth require special care, vaccination, medication or otherwise treated with surgery. The incidence of CHD has declined from 80 to 20% due to progress in heart surgery techniques, medical treatment and interventional cardiology. Various genetic and non-genetic increase the susceptibility for CHD. The diagnosis and treatment of CHD has greatly improved in recent years. Almost all the children with CHD survive to adulthood and spend healthy and active lives after being treated.
Several indigenous plants in Karachi region possessed various antimicrobial properties, among them some plants viz., Cyamopsis tetragonoloba (L.) Taub, Fagonia indica Burm f., Hibiscus rosa-sinensis L., Melia azedarach L., Prosopis juliflora (Sw.) DC., Rhynchosia minima (L.) DC., Solanum surattense Burm f., Terminalia catappa L., Thespesia populnea (L.) Sol. ex Corrêa, Withania somnifera (L.) Dunal were selected for present study. These plants were collected from different localities of Karachi and their grinded powders were used in vitro and in vivo against soil-borne plant pathogens like root-rot fungi and root-knot nematode. In vitro different parts of selected plants were extracted in five solvents such as water, methanol, n-hexane, chloroform and ethyl acetate. These extracts were tested against three root-rot fungi viz., Fusarium oxysporum Schltdl. emend. Snyd. & Hans., Macrophomina phaseolina (Tassi) Goid and Rhizoctonia solani (Kühn) by food-poisoned method on potato dextrose agar medium. Leaves, fruit and shoot extracts of selected plants significantly suppressed the growth of fungi as compared to stem extracts. However, H. rosa-sinensis (stem) extracts showed fungicidal activity than its leaves extracts. Among solvents, the water and methanol were found more effective against almost three fungi. Plants extracts were also tested against eggs hatching and mortality of second stage juveniles (J2) of root-knot nematode (Meloidogyne javanica (Treub) Chitwood) with varying concentrations (10, 5 and 2.5%). Significant reduction in the eggs hatching and increased in mortality was noticed in all plant extracts. Eggs hatching have been reduced and larval mortality has been increased when concentration of extracts increased therefore concentration 10% showed maximum nematicidal activity. Screen house trials were conducted in department of Botany, Federal Urdu University, to assess in vivo potential of plant species against targeted fungi and nematodes. Experiments carried out on okra (Abelmoschus esculentus (L.) Moench), mung bean (Vigna radiata (L.) R. Wilczek), cowpea (Vigna unguiculata (L.) Walp) and chickpea (Cicer arietinum L.). In soil amendment (organic amendment) experiment powder of plants were mixed in soil @ 0.5, 1 and 2% w/w fifteen days prior before sowing the seeds. T. populnea (leaves), M. azedarach (leaves), W. somnifera (leaves & stem), T. catappa xiii (leaves), P. juliflora (leaves), H. rosa-sinensis (stem), S. surattense (shoots) and C. tetragonoloba @ 1 and 2% showed more significant results than other plants. Amendment not only suppressed the incidence of root rot-root knot disease complex but it also enhanced the growth of test crops (okra & mung bean). Biochemical estimation of okra and mung bean also has been done after uprooting the crops. It was observed that T. populnea (leaves), M. azedarach (leaves) and W. somnifera (leaves) highly enhanced chlorophyll “a”, “b”, carotenoids and carbohydrate as compare to other treatments and control in okra. However, in mung bean S. surattense (shoots), H. rosa-sinensis (stem) and P. juliflora (leaves) highly enhanced the physiological parameters. Water extracts @ 1 and 2% w/v of selected plants has been used as soil drenching to check their efficacy. Both concentrations significantly promote growth of cowpea plant and also suppressed the infection caused by root-rot fungi and root-knot nematodes. However, W. somnifera (leaves) and S. surattense (shoots) extracts showed highly significant results as compared to others. The biochemical contents of cowpea showed increase in chlorophyll “a”, “b”, carotenoids, carbohydrate and decrease in phenol content. Combined application of microbial antagonists (Trichoderma harzianum & Pseudomonas aeruginosa), nematicide (Carbofuran) and fungicide (Aliette) in soil amended with plants dry powder @ 1 and 2% w/w showed remarkable suppression of root rot-root knot disease complex. While W. somnifera (leaves), S. surattense (shoots) and H. rosa-sinensis (stem) adequately affected on growth parameters of chickpea and reduced infection of targeted pathogens. On the other hand combination of plants powder (W. somnifera and S. surattense, H. rosa-sinensis and T. populnea) with P. aeruginosa, T. harzianum, Aliette and Carbofuran significantly enhanced biochemicals than other treatments.
