ماحولیاتی آلودگی اور اس کا سدباب: سیرت نبویﷺکی روشنی میں ایک تحقیقی جائزہ

Today, the whole world is facing the dangerious issues of environmental pollution. There is a lot of piles of garbage, plastic bags and waste are found in common routes and streets, the use of bacterial and antiseptic chemicals, smoking as well as the excessives use of machinery causes the abundance of smoke and due to the noise of vehicles, rugs, motorcycles, factories and airplanes, our daily pollution is increasing daily. As a result, many problems including various types of illness and seasonal variations are becoming a major challenge for today's modern era. In order to deal with it, it is important for us to study and follow the instructions of the Prophet (PBUH). Prophet (PBUH) has taken important measures to protect environmental pollution. He has prescribed some precautionary measures to prevent the spreading of dirt in society and keeping the environment clean to avert the soil pollution. For the purpose of aviation of air pollution, the prophet has ordered to populate it with the livestock andplantation. To cope with water pollution, it was emphasized to keep water clean and cleaness of air from odor and dirt. In this modern era, prevention of environmental pollution without following these instructions is impossible. This article has invesitaged on prevention of enviromental pollution and cleanliness of enviroment in the light of Sīrah.

Exploration of Anthelmintic, Antidiabetic and Anticancer Potential of in Vitro Cultures of Cichorium Intybus L. , Peganum Harmala L. and Withania Somnifera L. Dun.

The present study deals with the phytochemical analyses and determination of antimicrobial, anthelmintic, antidiabetic and anticancer potential of in vitro plant tissue and callus culture extracts of Cichorium intybus L., Peganum harmala L. and Withania. somnifera (L.) Dun. Maximum seed germination was observed in P. harmala seeds. Explants such as hypocotyl and cotyledon from in vitro seedlings were cultured on MS medium supplemented with different combinations and concentrations of plant growth regulators for callus induction. The most successful culture media were 0.05 TDZ + 0.5 NAA mg/L, 0.05 TDZ + 0.5 IBA mg/L and 0.05 TDZ + 0.5 BAP mg/L for callus induction of C. intybus, P. harmala and W. somnifera two for each respectively. Four different solvents depending upon polarity were used for extraction of explant tissues and callus cultures. Maximum percentage yield was recorded in chloroform extract of cotyledon callus cultures of C. intybus followed by chloroform extract of hypocotyl callus of P. harmala and cotyledon callus of W. somnifera respectively. Phytochemical analyses of extracts indicated the presence of valuable phytochemicals such as alkaloids, flavonoids, phenols, saponins, tannins, reducing sugars and terpenoids. Antimicrobial potential was tested against pathogenic bacteria (Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa) and fungi (Aspergillus niger and Fusarium solani). Maximum inhibition zones were recorded in methanol extracts of P. harmala and C. intybus hypocotyl callus culture against B. subtilis and E. coli respectively followed by chloroform and methanol extracts. Anthelmintic test showed that methanol extract of cotyledon callus culture of P. harmala exhibited considerable anthelmintic potential. Antidiabetic potential of methanol extracts of callus cultures was evaluated by using rabbits as experimental organisms. The extract of C. intybus hypocotyl callus culture showed maximum decrease in blood sugar level followed by the W. somnifera cotyledon callus culture in streptozotocin induced diabetic rabbits. Anticancer activity was conducted through HTC116 human colon cancer cell lines cultured in Dulbecco’s Modified Eagle Medium. Methanol extract of P. harmala hypocotyl callus cultures showed highest anticancer potential followed by chloroform extract of hypocotyl callus culture of C. intybus. It can be concluded that callus cultures of the plants selected for study hold auspicious ethno-pharmacological effectiveness and in vitro biomass production may be helpful for biodiversity conservation
