Effect of heavy cigarette and water pipe smoking on antioxidants and lipids in Sudanese male smokers: a case-control study

Background: Tobacco smoking is a source of many toxins such as free radicals, mutagenic substances as well as cause for developing cardiovascular diseases (CVD), particularly atherosclerosis. This study aims to assess the impact of smoking on antioxidants in Sudanese male smokers. Methods: Cases were 85 and 48 men who smoke cigarettes (CS) and water pipe (WPS) respectively and they were compared with matching 50 non-smoking controls. Blood samples were collected and following parameters: Glutathione peroxidase, Superoxide dismutase, Total cholesterol, Triglyceride, LDL, HDL, Paraoxinase, and Malondialdehyde were measured. Results: There were no significant differences in biochemical parameters between light CS and WPS compared to controls. In heavy smokers of both WPS and CS, the TC, TG, LDL, and MDA were higher than controls (p>0.05), GPx, SOD, HDL, and PON were lower in smokers than controls (p>0.05). In both groups of smokers, HDL, GPx, SOD, and PON were inversely correlated with duration of smoking (p>0.05), also, HDL was positively correlated with SOD and GPx (p>0.05). Moreover, GPx and SOD were correlated with each other in both groups of smokers (p>0.05). Conclusion: In Sudanese male smokers' biochemical profile disturbances suggest that heavy smoking was leading to developing CVD, particularly WPS

Vestibular assessment in chronic noise exposure subjects

Background: The damaging effect of noise on vestibular disturbance is well known, first described in 1890 by Haberman in tinkers with occupational hearing loss. Others have reported vestibular disturbances and abnormalities, such as balance disorders, dizziness, vertigo, and even spontaneous nystagmus in workers exposed to various kinds of occupational noise. Objective: To evaluate vestibular function in subjects with chronic noise exposure.Subjects and methods: Eighty subjects were included in the study, divided into 2 groups: 60 subjects exposed to noise in laundry with mean age 41.53±11.15 (study group) and 20 subjects not exposed to noise with mean age 38.60±6.48 (Control group). All subjects underwent audiovestibular evaluations (puretone audiometry, tympanometry, vedionystagmography, and posturography).Results: This study demonstrated elevated hearing threshold at audiometric frequencies 2-8 KHz (pv <0.001) and speech discrimination (pv <0.001). in addition, marked caloric weakness and reduced SOT composite scores (pv = <0.001), reduced SOT equilibrium scores in noise exposure subjects (pv<0.001), reduced SOT sensory scores in VEST and PREF (Pv <0.001). Furthermore, there was a positive correlation between duration of exposure and auditory and vestibular implications. Conclusion: this study revealed apparent effect of noise on auditory and vestibular system

Anti-schistosomiasis triterpene glycoside from the Egyptian medicinal plant Asparagus stipularis

Bioassay-guided isolation using an in vitro assay testing for anti- schistosomiasis yielded a novel triterpene saponin, asparagalin A, from the n-butanol extract of the roots of Asparagus stipularis Forssk., Asparagaceae. The structure was elucidated by spectroscopic analysis and chemical transformations. Administration of asparagalin A resulted in a retardation of worm growth and locomotion at the first day and showed a significant activity of egg-laying suppression at 200 µg/mL concentration.
