        Preoperative administration effect of metronidazole, ceftriaxone sodium and their combination on stenotic index of jejunal anastomotic segment of dogs

        Rafique, Rehan,Asi, Muhammad Nadeem,Saqib, Muhammad,Hussain, Muhammad Hammad,Sial, Awais-ur-Rehman,Mushtaq, Aqsa The Korean Society of Veterinary Science 2014 大韓獸醫學會誌 Vol.54 No.1

        The jejunum is the longest part of the small intestine and its lumen is mainly involved in the absorption of the nutrients. The present study was conducted to evaluate the effects of metronidazole, ceftriaxoine sodium and their combination on the stenotic index of the end to end jujunal anastomotic site. To accomplish this, 20 healthy stray dogs were subjected to end to end jejunal ansastmosis. Dogs in Group A (control) underwent jejunal anstomosis with no antibiotic prophylaxis, while those in Group B received surgery and metronidazole alone at 50 mg/kg, those in Group C received ceftriaxone sodium intravenously at 30 mg/kg body weight prior to surgery and dogs in Group D were given metronidazole in combination with ceftriaxone sodium at 50 mg/kg and 30 mg/kg, respectively, 2 h before surgical intervention. No significant difference (p > 0.05) in the stenotic index was observed at 14 days after jejunal anastomosis. These findings indicate that prophylactic administration of metronidazole and ceftriaxone sodium alone or in combination had no significant effect on the stenotic index of the jejunum.

        In vitro anticancer activities of Withania coagulans against HeLa, MCF-7, RD, RG2, and INS-1 cancer cells and phytochemical analysis

        Muhammad Maqsood,Rahmatullah Qureshi,Masroor Ikram,M. Sheeraz Ahmad,Bushra Jabeen,Muhammad Rafique Asi,Junaid Ahmed Khan,Safdar Ali,Lothar Lilge 한국한의학연구원 2018 Integrative Medicine Research Vol.7 No.2

        Background: The Pakistani Salt Range has a rich floral diversity including Withania coagulans from the Solanaceae family. Methods: The crude methanolic extracts of the root, leaf, leaf stalk, and fruit of this plant were screened for their cytotoxic activity against human (HeLa, MCF-7, RD) and rat (RG2 and INS-1) cancer cell lines at 20 μg/mL and compared to methotrexate. The IC50 values indicated that leaf stalk and fruit extracts exert an 80% or higher cytotoxic activity against all cell lines at 24 hours. Results: The leaf stalk extract showed the highest cytotoxic efficacy against all tested cell lines, with IC50 values ranging from 0.96 ± 0.01 μg/mL to 4.73 ± 0.05 μg/mL followed by the fruit extract with IC50 values of 0.69 ± 0.01–6.69 ± 0.06 μg/mL after 48–72 hours incubation. The leaf stalk and seed extracts were analyzed for polyphenols and flavonoids using RP-HPLC. The total flavonoid content (TFC) was calculated for all tested samples, and the highest TFC was recorded for the root extract (394.34 ± 1.26 μg/g). The total phenolic content (TPC) was found in the seed extract (307.86 ± 9.42 μg/g) of W. coagulans. The highest contents of myricetin (358.46 ± 2.91 μg/g) were noted in the leaf extract, and highest quercetin was recorded in the seed extract (21.43 ± 0.13 μg/g). The highest gallic acid concentration (83.62 ± 0.71 μg/g) was recorded in leaf stalk extract and p-hydroxybenzoic acid in the seed extract (157.46 ± 1.43 μg/g). Conclusion: The present study gives a scientific insight and comparative analysis of various plant parts in this medicinally important plant species from the Salt Range of Pakistan against both human and rat cancer cells.
