Epilepsy is a chronic neurologic disorder result from electrical disturbances that lead to abnormal discharge of neurons within the CNS. This discharge produced unprovoked and recurrent seizures which alter the normal brain functions. These functional alterations often give rise to behavioral abnormalities, with devastating effect on the patients and their families. To date, major advancement has been done in the treatment of epilepsy, but still, epilepsy is a great challenge in the medicine field which pays attention towards the invention of new and more potential AEDs. Regardless of latest advancement in the epilepsy, an about one third population is unresponsive. So, the proposed underlying mechanism of transfer of normal brain to epileptic is still unanswered and this highlight to identify new targets of drug treatement. For it , we established the seizure threshold, and used exogenous antiepileptogenic mediator i.e., isoxylitones [E/Z] to evaluate if this can control the over expressed JAK-STAT pathway in the model of epileptogenesis and finally discuss the attempts to halt the process of epileptogenesis by regulating the JAK-STAT pathway. From ancient time to present, there is a strong history of usage of plants and their extracts in the treatment of different neurological disorders. Delphinium denudatum is a medicinal plant of Himalayas and Kashmir, locally called Jadwar. This plant is claimed by many local practitioners to be used in seizure treatment. The novel antiepileptic compound ISO[E/Z] was initially isolated from the same plant and later it was synthesized. Previous studies in our lab already reported that ISO[E/Z] have potent antiepileptic effect. It is able to reduce the seizures in kindling model of epileptogenesis. This inhibition of seizure was further confirmed by modulation of BDNF, cfos and through blockage of sodium channel. In current study, we explored the effect of ISO[E/Z] at the molecular and cellular level by targeting JAK-STAT pathway, that is involved in the epileptogenesis process. The ISO[E/Z] was re-synthesized by our collaborator’s team, X therefore in order to validate and standardize the fresh supply of ISO[E/Z], we re-tested the compound both in acute and chronic seizure model. This step was carried out in order to keep compliance with previous findings. For present study, we choose JAK-1, JAK-3, STAT-2 and STAT-5a isoforms of JAK-STAT pathway due to their importance and involvement in the process of epileptogenesis. We found over expression of mRNA and protein of the above mentioned biomarkers in both cortex and hippocampus of untreated PTZ-kindled group. However, the treatment of ISO[E/Z] was able to reduced the JAK-1, JAK-3, STAT-2 and STAT5a expression. These findings suggest that ISO[E/Z] can halt the epileptogenesis progression by interrupting the underlying functional changes at molecular level. Moreover, our findings also validate our previous studies on isoxylitones with a promising compliance. In the light of all these observations, it can be said that isoxylitones in future would be a potential AED in the treatment of refractory epilepsy. At this stage, promising data support the further development of ISO[E/Z] as an inhibitor of JAK-STAT pathway and this strategy is expected to be valuable to modify or prevent the epilepsy. We think, for an adequate control, it is necessary to used a combination of drugs that hit the multiple targets which are the main players underlying epileptogenesis.

نشور ؔواحدی

نشورؔ واحدی
ہندوستان میں فراق گورکھپوری کا ماتم ابھی ختم نہیں ہوا تھا کہ نشور واحدی بھی داغِ مفارقت دے گئے، ان کا کلام ان کی دلکش اور مترنم آواز میں اعظم گڑھ کے مشاعروں اور دارالمصنفین کی نجی مجلسوں میں ان سے برابر سننے میں آیا، متین، سنجیدہ اور پرانی تہذیب کے حامل تھے، بلیاوطن تھا، مگر زندگی حلیم کالج کانپور میں ایک استاد کی حیثیت سے گذاری، شروع میں تعلیم دائرہ رفیع الزمان الہ آباد کے بزرگ شاہ شفاء اﷲ سے پائی جن سے فلسفۂ اسلام، فلسفۂ خودی اور مولانا روم کے افکار کے بہت سے رموز و نکات کو اچھی طرح سمجھا ان کا خوش گوار اثر ان کی شاعری پر بھی پڑا، ان کے کلام کے کئی مجموعے آتش ونم، شورنشور، صہبائے ہند اور فروغ جام کے نام سے شائع ہوئے، اصغر، حسرت، فانی، جگر اور فراق گورکھپوری کی صف کے بعد جو شعراء کھڑے نظر آئے، ان میں نشور واحدی اپنے شاعرانہ کمال کی گل پیرہنی، مشاگلی اور شیریں بیانی، پھر فکر و فن کے رنگ و آہنگ کی جلوہ گری میں کسی سے کم نہیں نظر آئے، بلکہ بعض حیثیتوں سے اپنے معاصروں میں قدآور دکھائی دیئے۔
۱۹۴۰؁ء میں جناب شاہ معین الدین احمد ندوی (سابق ناظم دارالمصنفین) نے ان کے مجموعۂ کلام ’’صبہائے ہند‘‘ کے شروع میں ایک مختصر تبصرہ میں لکھا تھا کہ ان کی شاعری میں تغزل کی رنگینیاں بھی ہیں، قوم و وطن کے لئے پیامِ زندگی بھی، مذہب و ملت کا درس بھی، الفاظ کی سلاست بھی، بیان کی لطافت بھی، معتدل شوخی بھی، اور جوش و سرمستی کے نمونے بھی ہیں، اپنی ان شاعرانہ خوبیوں کو انھوں نے آخر وقت تک قائم رکھا، نثر میں ان کی ایک کتاب اسلام میں فلسفۂ خودی پر بھی ہے، دعا ہے کہ ان کا اسلامی جذبہ بارگاہ...

لأزمة الأخلاقية في المجتمع الباكستاني المظاهر- العوامل- المعالجة

Moral values are seen as the basis of human civilization. Absence of moral values and responsibilities results in the justification of every evil in the society, as it is the case being observed in the present-day societies in many parts of the world. A nation, whose collective morals are high, is capable to lead other nations, irrespective of caste, creed and religious affiliations. If a nation, Muslim or non-Muslim, ignores the high moral values, it cannot avoid its decadence and destruction. Due to this utmost importance of morality for humanity, Islām regards morality as one of the integral parts of the Divine Revelation. Islām aims to create a sense of moral responsibility in its adherents, so that, they may show a complete picture of an ideal society, and enjoy their freedom to carry out the best possible moral deeds. The author of this paper, chose to study the present moral crisis in the Pakistani society and tried to determine the causes, which has brought about this moral crisis and also presents its cure in the light of the Qur’ān and Sunnah. The study focuses on the following aspects: Definitions of moral values & society, Prevalent social evils in our society, Causes of crimes and social evils, Remedies to root out unethical practices and evils from the society, Conclusion and recommendations.

دراسة تقدیة و عمرانیة لاسلوب کتابة عبداللھ بن المقفع مع الترکیز علی مدرسة الترسل الطبیعی لھ

A Critical and Sociological study of the literary style of Abdullah ibn al-Muqaffa with Focus on his Literary School: Natural expression. Due to scarcity of sufficient references and material on the subject of my thesis, I was obliged to follow methods of induction and survey of literature or obtaining and extracting necessary material and data. My research is ristricted to the following points. 1- Life of Abdullah Ibn Muqaffa with focus on his early environment and schooling under the care of his Magian parents and then his journey to Baghdad to enhance his exposure to a broader and deeper know-how of Arabic/Islamic Sciences and literature and then his literary and political life plus his reformative movement having led to his untimely death. All this followed by a critical discussion of his literary works and then critical evaluation of his thoughts and political wisdom with special focus on his theoretical philosophy and practical wisdom as extracted from his writings along with description of the salient features and traits whereby his literary works and thoughts are distinguished from his contemporaries and his predecessors all this followed by critical evaluation of different writers and critics' opinions/views about his life, writings and thoughts taking a different stand and at the same time synthesising different views in this connection. During working on my dissertation I followed methods of: 1- Induction 2- Survey of literature 3- Acquaintance and Description 4- Historical criticism All these are based on colligation of data and facts with observation of precision, penetration, necessary briefness and avoiding unnecessary and redundant details.
