    Includes bibliographical references (p. 354-369).This study explores the experiences of the rank-and-file soldiers of Umkhonto we Sizwe and the Azanian People's Liberation Anny. Extensive interviews by the author and other researchers reveal the voices of the soldiers themselves. The African National Congress and Pan African Congress archives at the University of the Western Cape and the University of Fort Hare supplement and verify these oral testimonies, as do some published sources. Most previously published materials about the armed struggle against apartheid have already focused on diplomacy, strategy and tactics, operations, leadership, and human rights abuses to the neglect of the soldiers' actual experiences. This study complements these with significant new oral history materials from the Soweto generation of soldiers and their successors. When dealing with MK, many authors have documented issues of the camp structure in Angola, and operations inside South Africa, so much of this detail is only addressed briefly, leaving space to explore the soldiers' experiences. In the case of APLA, very little has been written on its history, and more detail is provided on these subjects. This study therefore deals with the soldiers' politicisation and motivation for joining the armed struggle, their experiences in leaving South Africa and training in exile, the crises in exile which limited their effectiveness for a time, their return to fight in South Africa, and their difficulties in the "new" South Africa. These materials reveal that vast problems remain facing these veterans of the struggle against apartheid, and that they have the potential, if properly supported and employed, to contribute substantially to the development of present day South Africa. Conversely, if their neglect continues, they also have the potential to bring vast harm to the country. Further use of the investigative tools of oral history, especially if extended to the former soldiers' vernacular languages, is necessary to augment the history of South Africa, and these soldiers' contributions

    Conservation in an Islamic context a case study of Makkah

    No full text
    The Holy Qu’ rān contains many injunctions for Muslims to respect and conserve the natural environment but few address the built environment. Habitat at the time of the Prophet (PBOH) was in the vernacular and relatively impermanent. The first habitat was the cave, the second the tent and then simple flat roofed buildings of post and lintel construction made of mud and rubble. Later buildings were not indigenous but reflected the architectural styles and techniques of Muslim pilgrims from beyond the Arabian Peninsula. Permanent exotic buildings were later erected as reminders of holy places and events. This work advances a case to restore and preserve historic and religious sites in Makkah, Saudi Arabia. Makkah is the destination for millions of Muslim pilgrims who annually pay homage to Allah during the occasions of Hajj, Ramadan and Umra. The tranquillity and peaceful ambience that one associates with the holiest of Islamic experiences have, over the years, given way to jostling crowds of people who must be expediently housed, fed, transported, and protected. Due to the lack of planning and the insensitive but profitable development of the city, Makkah is in grave danger of becoming a bustling metropolis instead of a sanctuary where pilgrims gather to perform their religious rites and reaffirm their dedication to Allah. The author calls for professional planning and international cooperation to guide future development for this expanding and sensitive area. The author's ideas are grounded in practical and aesthetic study, therefore, the political, environmental and economic issues are examined in relationship to religious, historic and artistic values. The author makes proposals for a future Makkah that would provide pilgrims with the physical comforts, security, and serene environment they deserve—without destroying the city they came to visit. The author discusses preservation and conservation in the western world and the need for their acceptance in Muslim countries, the former being an aesthetic and intellectual concept sustained by law and the latter being the prescribed free expression of the individual unhindered by material considerations. Both worlds are rapidly being overwhelmed by materialism, but body, mind and spirit combine in making us aware of our surroundings and the way in what we see around us has come into being

DR treatment relies on invasive techniques associated with various complications. Investigating topical routes for Apa delivery to the posterior eye segment is thus promising but also challenging due to ocular barriers. Hence, the study objective was to develop Apa-loaded bovine serum albumin nanoparticles (Apa-BSA-NPs) coated with hyaluronic acid (HA); a natural polymer possessing unique mucoadhesive and viscoelastic features with the capacity to actively target CD44 positive retinal cells, for topical administration in DR.Methods: Apa-BSA-NPs were prepared by desolvation using glutaraldehyde for cross-linking. HA-coated BSA-NPs were also prepared and HA: NPs ratio optimized. Nanoparticles were characterized for colloidal properties, entrapment efficiency (EE%), in vitro drug release and mucoadhesive potential. In vitro cytotoxicity on rabbit corneal epithelial cells (RCE) was assessed using MTT assay, while efficacy was evaluated in vivo in a diabetic rat model by histopathological examination of the retina by light and transmission electron microscopy. Retinal accumulation of fluorescently labeled BSA-NP and HA-BSA-NP was assessed using confocal microscope scanning.Results: Apa-HA-BSA-NPs prepared under optimal conditions showed size, PdI and zeta potential: 222.2± 3.56 nm, 0.221± 0.02 and − 37.3± 1.8 mV, respectively. High EE% (69± 1%), biphasic sustained release profile with an initial burst effect and mucoadhesion was attained. No evidence of cytotoxicity was observed on RCE cells. In vivo histopathological studies on DR rat model revealed alleviated retinal micro- and ultrastructural changes in the topical HA-Apa-BSA-NP treated eyes with normal basement membrane and retinal thickness comparable to normal control and intravitreally injected nanoparticles. Improved retinal accumulation for HA-BSA-NP was also observed by confocal microscopy.Conclusion: Findings present HA-Apa-BSA-NPs as a platform for enhanced topical therapy of DR overcoming the devastating ocular complications of the intravitreal route.Keywords: retinopathy, apatinib, bovine serum albumin, hyaluronic, mucopenetration, active targetin

    AbstractObjectiveThis randomized, double blind, controlled study was designed to test whether the intraoperative use of intravenous lidocaine bolus followed by infusion would attenuate the tourniquet induced hypertension (TIH) in patients undergoing anterior cruciate ligament reconstruction (ACLR) under general anesthesia.Methods76 patients were randomly allocated into two equal groups. Lidocaine group (group L), in which patients received lidocaine 2% 1mg/kg IV bolus after induction of anesthesia followed by lidocaine infusion (2mg/kg/h) and placebo group (group P), in which patients received equal volumes of saline. Heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded before induction of anesthesia, before tourniquet inflation (baseline value), every 15min after tourniquet inflation, and after tourniquet deflation. The number of patients who developed TIH was recorded and total amount of propofol and fentanyl used intraoperative was recorded.ResultsSBP, DBP and HR were significantly less after tourniquet inflation in group L compared to group P in most of the time periods after tourniquet inflation (p value<0.05), the number of patients developed TIH was significantly less in group L compared to group P (26% in group L compared to 52.6% in group P) (p value 0.019), and the total amount of propofol and fentanyl used intraoperative was significantly less in group L compared to group P (p value 0.000).ConclusionIntraoperative use of lidocaine bolus (1mg/kg), followed by infusion (2mg/kg/h), started 10min before tourniquet inflation attenuated the TIH in patients undergoing anterior cruciate ligament reconstruction under general anesthesia

    AbstractObjectiveThis study was conducted to compare two techniques of sedation for obese patients undergoing ERCP, using either ketofol or fentanyl–propofol as regards propofol consumption, recovery time, patients’ satisfaction, and sedation-related adverse events.Materials and methodsTwo hundred obese patients were randomly allocated to one of two groups; ketamine/propofol (ketofol) group KP (n=100) or fentanyl/propofol group FP (n=100). The level of sedation was adjusted to achieve a Ramsay Sedation Scale (RSS) score of 5.ResultsTotal dose of propofol consumed was significantly higher in group FP compared with group KP (97.08±23.31mg and 57.71±16.97)mg. Recovery time was slightly longer in group KP compared with group FP (11.19±2.59min and 9.43±1.23min, respectively), time needed to achieve Aldrete Recovery Scale Score of 9 was comparable in both groups, and sedation-related side effects as hypotension, bradycardia, apnea, and reduction of SpO2 were more significant in the FP group.In conclusionKetamine/propofol combination 1:4 provided better sedation quality than fentanyl/propofol combination with less side effects and can be safely used for sedating obese patients undergoing ERCP

    AbstractObjectiveThis study was designed to evaluate the effect of adding ultra-low dose of naloxone as an adjuvant to lidocaine for intravenous regional anesthesia (IVRA).MethodForty patients undergoing elective short procedures in the upper limb were randomly and blindly divided into two groups of twenty patients each. Group L (n=20) received 3mg/kg of 2% lidocaine diluted with normal saline to 30ml. Group LN (n=20) received 3mg/kg of 2% lidocaine and naloxone 100ng (1ml) diluted with normal saline to 30ml. Onset and recovery time of sensory and motor block, intraoperative and post-operative pain were measured by visual analog score (VAS), and also intraoperative analgesic requirement, time of first requirement of diclofenac postoperatively, total amount of diclofenac needed in 24h, patient’s satisfaction and surgeon’s satisfaction scores were measured.ResultsRecovery of sensory block was significantly longer in group LN (26.7±2.8min) compared to group L (16.3±0.6min); p value (0.000). Also the recovery of motor block was significantly longer in group LN (19.1±1.0min) compared to group L (17.9±1.2min), p value (0.002). Intraoperative fentanyl requirement was significantly less in group LN (15.8±5.0mcg) compared to group L (40.0±10.5mcg), p value (0.000). 1st fentanyl requirement time was significantly longer in group LN (22.4±3.1min) than in group L (14.5±6.1min), p value (0.000). Time of first analgesic requirement post-operative was longer in group LN (78.5±6.8min) compared to group L (40.5±2.0min), p value (0.000). Total amount of diclofenac needed in 24h was significantly less in group LN (57±50mg) compared to group L (120±45mg), p value (0.000).ConclusionThe addition of ultra-low-dose naloxone 100ng to lidocaine for IVRA in upper limb surgery, prolonged the duration of sensory and motor block, and reduced tourniquet pain, as well as intraoperative and postoperative analgesic consumption
