ایک حادثہ المناک]مولانا ظفر احمد خاں[
۱۳؍دسمبر ۱۹۷۹ء جمعرات کی شب میں ایک بجے مولانا محمد ظفر احمد خاں صاحب رحلت فرماگئے۔ اناﷲ واناالیہ راجعون۔ ۱۹۳۸ء میں یہ ادارہ قائم ہوا۔ مولانا مرحوم ۱۹۳۹ء میں ندوۃ المصنفین میں بحیثیت کارکن ومنیجر تشریف لائے۔ موصوف کارسالہ برہان اورادارہ ندوۃ المصنفین سے دیرینہ تعلق تھا۔مرحوم کا حضرت مفتی صاحب سے تعلق چالیس ۴۰ سال رہا۔ اوراسی دوران جب سے دفتر کی ذمہ داریاں میرے سپرد کی گئی تھیں وہ ۱۹۶۸ء تھا، زیادہ تراسی وقت سے میرا مرحوم سے قُرب رہا۔موصوف پُرخلوص نیک دل انسان تھے اور وفاداری ان کے مزاج میں بے پناہ پائی جاتی تھی۔موصوف اپنی خود ایک مثال تھے۔ادارہ ندوۃ المصنفین کے وفادار اورایک اعلیٰ معیار کے کارکنوں میں ان کاشمار تھا۔مولوی صاحب میرے لیے سہارا اور ڈھارس تھے کیونکہ مجھ کو اُن سے حوصلہ افزائی اور تقویت حاصل تھی۔ مولوی صاحب کی جدائی میرے واسطے ایک بھیانک انقلاب ہے۔مجھ کویہ دلی صدمہ پہنچا ہے دعافرمائیں کہ مزید ذمہ داریاں سنبھالنے کی اﷲ تعالیٰ مجھ کو بہترین صلاحیتوں سے نوازدیں۔آمین ثم آمین۔
مولوی صاحب اس جہانِ فانی سے رخصت ہونے کے چھ گھنٹے قبل تک رسالہ برہان کاکام انجام دیتے رہے۔ [منیجر ندوۃ المصنفین دہلی، جنوری ۱۹۸۰ء]

EFFECTS OF RELAXING MUSIC THERAPY ALONG WITH TASK-ORIENTED TRAINING OF LOWER LIMB ON BALANCE AND FUNCTIONAL INDEPENDENCE IN PATIENTS WITH CHRONIC STROKE: A RANDOMIZED CLINICAL TRIAL

Background of the Study: To compare the effects of relaxing music therapy with task-oriented training of lower limbs on the balance and functional status in patients with chronic stroke. Methodology: This randomized clinical trial was conducted in three outpatient physiotherapy clinics in Lahore, Pakistan. A sample of 76 participants with chronic stroke, aged 40-60 years, and on assistance walking, were recruited through a purposive sampling technique. Individuals who had physical impairments and visual or hearing deficits were not included in the study. Group A received task-oriented training with routine physical therapy while Group B received Music therapy additionally. Three sessions on alternate days per week for eight weeks were given. Balance and functional independence were the outcome variables measured using the Berg Balance Scale and Functional Independence Measure respectively. Mann-Whitney U test and Friedman ANOVA were applied for between-group and within-group differences respectively. P-value was significant at ≤0.05. Results: The mean age of participants was 54.05 ± 3.64 years, the majority i.e., 55 (72.4%) were male, 46 (60.5%) had ischemic stroke and 53 (69.7%) were presented with left-sided weakness. A statistically significant difference was observed among both groups in balance (p =.000) and functional independence (p=0.000). The within-group difference was also significant for balance (p=0.000) and functional independence (p=0.000). Conclusion: The integration of relaxing music therapy, task-oriented training, and routine physiotherapy is effective in improving balance and functional independence in chronic stroke patients.

Evaluation of Esterases and Phosphatases in Three Strains of Callosobruchus Chinensis and Rhyzopertha Dominica Treated With Plant Extracts and Synthetic Pyrethroids

Stored grains have been attacked by different insect species for many years. To protect stored grains from insect attack, various control measures have been suggested. Current research was initiated in order to assess five plant extracts and three synthetic pyrethroids for their toxic and repellent efficiency and their effect on progeny inhibition of three strains of Callosobruchus chinensis and Rhyzopertha dominica. These treatments were also studied for their subsequent effects on the certain esterases and phosphatases enzymes of test insects. Azadirachta indica extract and deltamethrin were more effective. Significant mortality was obtained at the highest concentrations, after maximum exposure time. C. chinensis mortality with A. indica was 81.10, 69.23 and 86.82% in FSD, MLN and NNS strains respectively. 100% mortality was achieved with deltamethrin for all strains of C. chinensis. R. dominica mortality with A. indica was 65.19, 60.74 and 84.96% FSD, MLN and NNS strains respectively. Deltamethrin resulted in 95.56, 95.56 and 97.75% mortality of R. dominica Faisalabad, Multan and Nankana strain respectively. A. indica resulted in 79.99, 66.67 and 80.81% progeny inhibition of C. chinensis Faisalabad, Multan and Nankana strain respectively. 66.77, 60.32 and 70.40% reduction in progeny production of C. chinensis was achieved with deltamethrin, in Faisalabad, Multan and Nankana strain respectively. A. indica caused 90.22, 88.01 and 92.23% progeny inhibition of R. dominica in Faisalabad, Multan and Nankana strain respectively. Progeny inhibition of R. dominica was 90.46, 80.93 and 97.14% in Faisalabad, Multan and Nankana strain respectively with deltamethrin. In repellency bioassay, A. indica resulted in 93.33, 90.67 and 94.67% repellency in C. chinensis Faisalabad, Multan and Nankana strain, respectively. With deltamethrin repellency was 92.00, 90.67 and 97.33% in C. chinensis Faisalabad, Multan and Nankana strain respectively. Percentage repellency in in case of R. dominica was 94.67, 85.33 and 92.00 in Faisalabad, Multan and Nankana strain respectively, with A. indica. Repellency recorded with deltamethrin, in R. dominica was 90.67, 89.33 and 92.67% in Faisalabad, Multan and Nankana strain respectively. In case of enzymatic analysis, the inhibition of treatments was compared with the control. With A. indica treatment, in C. chinensis FSD strain, maximum AChE, ALP, ACP, α-CE and β-CE inhibition was 45.82, 29.98, 61.38, 43.65 and 50.81% respectively, 57.14, 39.98, 58.24, 41.04 and 50.58% respectively in MLN strain and 41.31, 28.87, 61.67, 45.24 and 50.32% respectively in NNS strain. Using M. azadirach, in C. chinensis FSD strain, maximum AChE, ALP, ACP, α-CE and β-CE inhibition was 55.82, 29.98, 53.37, 45.48 and 51.30% respectively, 63.81, 39.98, 52.67, 43.65 and 50.33% respectively in MLN strain and 51.98, 31.10, 52.84, 47.96 and 50.57% respectively in NNS strain. In pyrethroids, cypermethrin mostly resulted in high inhibition of enzymes. So, with cypermethrin maximum AChE, ALP, ACP, α-CE and β-CE inhibition was19.14, 18.54, 47.65, 36.33 and 42.45% respectively, in C. chinensis FSD strain, 37.14, 21.09, 48.42, 36.33 and 39.12% respectively, in MLN strain and 14.96, 17.43, 46.95, 38.32 and 39.99% respectively in NNS strain. In R. dominica FSD strain, treated with A. indica maximum AChE, ALP, ACP, α-CE and β-CE inhibition was 39.42, 43.77, 47.79, 41.38 and 52.30% respectively, 37.57, 39.94, 47.31, 41.90 and 48.46% respectively in MLN strain and 40.41, 45.99, 51.59, 42.15 and 50.51% respectively in NNS strain. With M. azadirach treatment, in R. dominica FSD strain, maximum AChE, ALP, ACP, α-CE and β-CE inhibition was 40.83, 42.94, 45.71, 40.47 and 47.84% respectively, 39.70, 39.94, 44.13, 40.99 and 43.86% respectively in MLN strain and 41.83, 45.17, 51.59, 42.15 and 50.51% respectively in NNS strain. Using pyrethroids, enzymes inhibition was recorded maximum in R. dominica NNS strain with cypermethrin, which resulted in 34.03, 43.80, 49.45, 31.41 and 48.34% inhibition of AChE, ALP, ACP, α-CE and β-CE respectively as compared to the control treatment.
