Sucralfate Enemas
Sucralfate Enemas Sucralfate enemas are used to treat inflammation of the rectum (the lower part of the large intestine leading to the anus); most commonly this is for radiation proctitis; bowel inflammation following radiotherapy. This treatment can help treat bleeding due to the inflammation, and can be continued for up to 24 weeks; you can stop when the bleeding stops. This fact sheet explains how you can administer the enema yourself, using a syringe and catheter. The hospital or community pharmacy can provide the Sucralfate enema, and you will need to ask your GP or practise nurse to supply the equipment you will need. Your practise nurse can help you practice preparing the enema, and could help you with administering it at home, if you find this difficult. 1. Using the syringe provided, draw up 10mls of the Sucralfate Suspension (2g) and then draw up 10mls of warm water and mix. Ensure that any excess air is expelled from the syringe. 2. Attach the catheter provided to the syringe tip and lubricate the end of the catheter with lubricating gel provided. 3. Lie on your left side with both knees bent. This position will help the flow of liquid in to the rectum and aid enema retention. 4. Position a towel underneath yourself to catch any leakage of fluid once the enema has been administered. 5. With a steady pressure, gently insert the catheter to a depth of approximately 10cm into the rectum. 6. Press down on the barrel of the syringe slowly, using a steady and even pressure, until the entire contents of the syringe have been administered. -

Different aspects of MSC biology were explored and published. Studies pointed to their localization in different organs during development and in adulthood and described their characteristics in experimental or clinical investigations. Despite intensive research in the field and in sharp contrast to hematopoietic stem cells (HSC), it has become more and more clear that MSC lack a unique cell surface marker. MSC not only share cell surface markers with other types of cells, they also share many features with pericytes and fibroblasts, including their capability to differentiate into, for instance, osteoblasts or adipocytes. -
Injection of Stabilized Hyaluronic Acid-Based Gel of Non-Animal Origin for the Correction of Nasolabial Folds: Comparison with and Without Lidocaine
Injection of Stabilized Hyaluronic Acid-Based Gel of Non-Animal Origin for the Correction of Nasolabial Folds: Comparison with and without Lidocaine à y à z PER HEDE´ N,PHD, DAN FAGRELL, MD, JAN JERNBECK, MD, RICHARD RYLANDER, MD, à z z ULF SAMUELSON,PHD, GABRIELLA SELLMAN, MD, AND BIRGIT STARK,PHD BACKGROUND The use of injectable hyaluronic acid–based gel of non-animal origin, manufactured using the patented NASHA technology, is well established in aesthetic facial procedures. OBJECTIVE To compare injection pain, dermal filler efficacy, and safety of NASHA-based gel with or without 0.3% lidocaine hydrochloride when administered to the nasolabial fold (NLF). METHODS Forty-three subjects seeking correction of NLFs, with moderate or severe wrinkle severity, were recruited for this split-face, double-blind, comparative study. NASHA-based gel, with or without lidocaine hydrochloride, was injected into the deep layer of the dermis and/or subcutis, of the NLF. Pain, efficacy, and safety assessments included a treatment preference question, a 100-mm visual analogue scale for pain, the Wrinkle Severity Rating Scale, and adverse event reporting. RESULTS Ninety percent of subjects (lower 95% confidence limit=76%) rated injection of NASHA- based gel with lidocaine as less painful than NASHA-based gel alone. Subjects and physicians reported no significant differences in dermal filler efficacy between the two treatments during the 12-month follow-up period. The safety profile was similar for both products. CONCLUSION NASHA-based gel with lidocaine provides a more comfortable treatment experience than NASHA-based gel alone, with equivalent efficacy and safety observed after 12 months of follow-up. -

Effects of Collagen-Derived Bioactive Peptides and Natural Antioxidant
www.nature.com/scientificreports OPEN Efects of collagen-derived bioactive peptides and natural antioxidant compounds on Received: 29 December 2017 Accepted: 19 June 2018 proliferation and matrix protein Published: xx xx xxxx synthesis by cultured normal human dermal fbroblasts Suzanne Edgar1, Blake Hopley1, Licia Genovese2, Sara Sibilla2, David Laight1 & Janis Shute1 Nutraceuticals containing collagen peptides, vitamins, minerals and antioxidants are innovative functional food supplements that have been clinically shown to have positive efects on skin hydration and elasticity in vivo. In this study, we investigated the interactions between collagen peptides (0.3–8 kDa) and other constituents present in liquid collagen-based nutraceuticals on normal primary dermal fbroblast function in a novel, physiologically relevant, cell culture model crowded with macromolecular dextran sulphate. Collagen peptides signifcantly increased fbroblast elastin synthesis, while signifcantly inhibiting release of MMP-1 and MMP-3 and elastin degradation. The positive efects of the collagen peptides on these responses and on fbroblast proliferation were enhanced in the presence of the antioxidant constituents of the products. These data provide a scientifc, cell-based, rationale for the positive efects of these collagen-based nutraceutical supplements on skin properties, suggesting that enhanced formation of stable dermal fbroblast-derived extracellular matrices may follow their oral consumption. Te biophysical properties of the skin are determined by the interactions between cells, cytokines and growth fac- tors within a network of extracellular matrix (ECM) proteins1. Te fbril-forming collagen type I is the predomi- nant collagen in the skin where it accounts for 90% of the total and plays a major role in structural organisation, integrity and strength2. -
Formulation of Topical Bioadhesive Gel of Aceclofenac Using 3-Level Factorial Design
Archive of SID Iranian Journal of Pharmaceutical Research (2011), 10 (3): 435-445 Copyright © 2011 by School of Pharmacy Received: September 2009 Shaheed Beheshti University of Medical Sciences and Health Services Accepted: February 2010 Original Article Formulation of Topical Bioadhesive Gel of Aceclofenac Using 3-Level Factorial Design Sanjay Singh*, Rabinarayan Parhi and Anuj Garg Department of Pharmaceutics, Institute of Technology, Banaras Hindu University, Varanasi, 221005, India. Abstract The objective of this work was to develop bioadhesive topical gel of Aceclofenac with the help of response-surface approach. Experiments were performed according to a 3-level factorial design to evaluate the effects of two independent variables [amount of Poloxamer 407 (PL-407 = X1) and hydroxypropylmethyl cellulose K100 M (HPMC = X2)] on the bioadhesive character of gel, rheological property of gel (consistency index), and in-vitro drug release. The best model was selected to fit the data. Mathematical equation was generated by Design Expert® software for the model which assists in determining the effect of independent variables. Response surface plots were also generated by the software for analyzing effect of the independent variables on the response. Quadratic model was found to be the best for all the responses. Both independent variable (X1 and X2) were found to have synergistic effect on bioadhesion (Y1) but the effect of HPMC was more pronounced than PL-407. Consistency index was enhanced by increasing the level of both independent variables. An antagonistic effect of both independent variables was found on cumulative percentage release of drug in 2 (Y3) and 8 h (Y4). Both independent variables approximately equally contributed the antagonistic effect on Y3 whereas antagonistic effect of HPMC was more pronounced than PL-407.
