والدہ، ڈاکٹر جوہر قاضی

ڈاکٹر جوہر قاضی والدہ
تعزیت
رُکن مجلسِ ادارت اعزازی ماہنامہ برہان ڈاکٹر جوہر قاضی کی والدہ محترمہ ۵؍ جولائی ۱۹۹۷ء کو شنبہ کی صبح مختصر علالت کے بعد دہلی میں اپنی رہائش گاہ پر انتقال کرگئیں۔انا ﷲ وانا الیہ راجعون۔
مرحومہ کی عمر تقریباً پچھترسال تھی۔ وہ ایک دین دار خاتون تھیں۔ان کی وفات بلاشبہ ڈاکٹر جوہر قاضی،اہل خاندان اوران کے رفیق سفر جناب حکیم قاضی محمدیٰسین عالم صاحب مدیر اعلیٰ ماہنامہ ’راحت وصحت‘ کے لیے ایک عظیم صدمہ ہے۔ میں اپنی طرف سے اور کارکنانِ ادارہ کی طرف سے دعا کرتا ہوں کہ اﷲ تعالیٰ مرحومہ کواپنے جوار رحمت میں جگہ دے اور لواحقین کو صبرجمیل عطا فرمائے۔
ہم جناب ڈاکٹر جوہرقاضی اوران کے اہل خاندان کے اس غم میں برابر کے شریک ہیں۔مجھے بذاتِ خوداس سانحۂ ارتحال سے سخت جھٹکا لگاہے۔
[عمیدالرحمن عثمانی،جولائی واگست ۱۹۹۷ء]

 

عصر حاضر میں حصول انصاف میں مشکلات مسلم فکر کا تجزیاتی مطالعہ

Islam has given a complete code of life to run the system of this universe, which started with the arrival of Hazrat Adam (A.S) in this world and was completed with the Prophet (P.B.U.H). It is a comprehensive and system in which the individual and the rights and duties of both congregations are based on the concept of justice and fairness. Under this system of Islam, the supreme command on earth is only Allah’s persons, the position of man is that of vicegerent and caliph, mans responsibility is to carry out all the affairs of life according to the will of Allah. The earth and its resources will created for the benefits of all mankind. All human beings have the right to use them according to their needs, but no individual has the right to seize or hoard these resources to the detriment of others. Just as every person has rights, such as protection of life and property, honor and reputation, so it is also his duty to provide comfort and relief to no other people and not to cause any harm to anyone.

Bioevaluation of Cabbage Based Designer Food to Modulate Oxidative Stress Markers

Nowadays, plants bioactive moieties are gaining attention amongst the masses to mitigate lifestyle related dysfunctions owing to their safe nature and functional properties. Considering phytochemistry and cost-effectiveness of cabbage, the current project was designed to probe the antioxidant capacity of locally grown green and red cabbage with special emphasis on modulation of oxidative stress biomarkers in response to hypercholesterolemic diet. Purposely, green and red cabbage samples were analyzed for compositional analyses that depicted high proportion of potassium and vitamin C in both samples. The red cabbage showed higher amount of total polyphenols & flavonoids (224.37±6.96 & 219.15±10.30 mg/100g F.W.) than green cabbage (58.41±3.01 & 34.04±1.06 mg/100g F.W.) along with the existence of anthocyanins (69.86±4.12 mg/100g F.W.) in red cabbage only. Comparative HPLC analysis regarding antioxidant moieties showed significant proportion of kempferol (171.10±5.99 mg/100g F.W.) and vitamin C (139.07±2.23 mg/100g F.W.) in red cabbage however, vitamin C (121.46±3.28 mg/100g F.W.) was found as the major antioxidant in green cabbage. The red cabbage depicted higher free radical quenching and reducing ability in contrast to green cabbage using DPPH (1, 1-diphenyl-2- picrylhydrazyl), ABTS [2, 2''-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid)], FRAP (ferric reducing antioxidant power) and PFRAP (potassium ferricyanide reducing antioxidant power) reagents. The corresponding assays were ranged from 31.22±1.65 to 87.79±3.69%, 1.51±0.07 to 6.04±0.21 μM Trolox/g F.W., 0.95±0.04 to 1.16±0.04 μM Fe2+/g F.W., 41.16±2.10 to 59.32±2.14% and 48.03±1.68 to 63.45±3.05%. In the product development phase, four types of croquettes based on green and red cabbage leaves & their respective aqueous extracts along with control were stored under frozen conditions and analyzed at three different intervals; 0, 15 & 30 days, employing two types of cooking procedures; baking and frying. The resultant prototypes were assessed for physicochemical analyses (caloric count, color, texture, water activity & antioxidant assays) as well as sensory response. The current study portrayed that designer croquettes remained freezer friendly for one month without employing any preservative. Comparative assessment of cooking methods inferred higher antioxidant potential and taste scores for fried prototypes. Based on antioxidant assays and overall acceptability, red cabbage and its respective aqueous extract were screened for biological evaluation. In animal study (12 weeks), male white New Zealand rabbits were divided into six groups; three groups under normal dietary pattern; normal diet, normal diet+cabbage leaves & normal diet+cabbage extract and next three under hypercholesterolemic dietary regimen; hypercholesterolemic diet, hypercholesterolemic diet+cabbage leaves & high calorie+aqueous cabbage extract. At termination, overnight fasted rabbits were sacrificed to assess serum lipid profile. The percent reduction in serum cholesterol and LDL by red cabbage & its extract was reported up to 10.79 & 15.19 and 12.24 & 18.09 in hypercholesterolemic rabbits, respectively. Furthermore, serum specific and tissues (liver, heart & kidney) oxidative stress biomarkers alongside, their somatic index and histopathology were studied. The red cabbage supplementation suppressed the leakage of liver functioning enzymes in sera up to 15.63% (ALT), 13.88% (ALP), 12.96% (ɤ-GT) and 10.77% (total bilirubin) besides reduction in hepatic lipid peroxidation up to 29.60% thus improved endogenous antioxidant enzymes. Likewise, red cabbage showed protection against cardiac oxidative stress. Additionally, the red cabbage extract lowered renal MDA (lipid peroxidation) up to 24.07% in oxidative stressed rabbits that ultimately restored renal SOD (11.38%) and CAT (16.72%), accordingly. The hepatosomatic index (HSI) and nephrosomatic index (NSI) expounded significant impact of treatments on hypercholesterolemic diet fed rabbits except cardiosomatic index (CSI). In hypercholesterolemic rabbits, mild degree of fibrotic and necrotic changes in hepatic parenchyma were rectified by red cabbage supplementation, whereas red cabbage extract based diet showed slower rate of amelioration. Likewise, mild degree of necrotic changes and congestion in cardiac fenestrations were modulated by red cabbage feeding. Moreover, severe necrotic & pyknotic alterations in renal parenchyma along with mild to moderate degree of congestion in hypercholesterolemic rabbits were effectively reversed via extract supplemented group in contrast to cabbage fed group. In the nutshell, dietary inclusions based on red cabbage has proven restorative against hepatic and cardiac compromised conditions, whereas altered renal fenestrations were also effectively restored by red cabbage extract enriched diet.
