Effect of interventions with ingestion of legumes and/or supervised exercise on the lipid profile of young, healthy sedentary women / Efecto de las intervenciones con ingesta de leguminosas y/o ejercicio supervisado sobre el perfil lipídico de mujeres jóvenes, sanas y sedentarias

Objective: To contribute to the knowledge of some aspects of the Healthy Life Style by studying the effects of including legumes in the diet and exercise at two intensity levels, along with the lipid profile of young sedentary women living at 2640 meters above sea level. Materials and methods: The study included a non-randomized clinical trial with four intervention groups: exercise at 45% VO2 peak plus legumes in diet, exercise at 65% VO2 peak plus legumes in diet, only exercise at 65% VO2 peak, and only inclusion of legumes in diet. In each group, 20 to 23 sedentary women were included. The intervention was carried out for four weeks, three days a week. Exercise prescription was based on measurement of VO2 peak by ergospirometry; and the current intervention was monitored with heart-rate monitors. The outcome variables were total serum cholesterol, LDL cholesterol, HDL cholesterol, and triacylglycerols measured at baseline and after two and four weeks of intervention. Results: The measurements taken of participants in the group of exercise at 65% VO2 peak plus legumes in diet showed a reduction of 19.8 mg/dl in total cholesterol, of 21.8 mg/dl of LDL cholesterol, of 20.7 mg/dl of tracylglycerol, and an increase of 6.2 mg/dl of HDL cholesterol. The serum levels of HDL also increased in the group of only exercise at 65% VO2 peak. No significant changes in serum levels were documented for participants in the group with only dietary modifications. Conclusions: The results suggest that different interventions that meet some of the criteria for healthy eating and life style show different effects with regards to the level of change in the lipid profile components.

Objetivo: Contribuir al conocimiento de algunos aspectos prácticos para llevar a cabo una alimentación y estilo de vida saludable, mediante el estudio de los efectos en el perfil lipídico de la inclusión de leguminosas (fríjol, lenteja y garbanzos) en la dieta de mujeres sanas pero sedentarias, acompañada de ejercicio con dos niveles de intensidad, moderada y alta, efectuados a una altura de 2,640 metros sobre el nivel del mar (msnm). Material y métodos: Estudio de intervención clínica no aleatorizada con cuatro grupos de intervención: ejercicio a 45%VO2 pico + leguminosas, ejercicio a 65%VO2 pico + leguminosas, sólo ejercicio a 45%VO2 pico y sólo inclusión de leguminosas en la dieta. En cada grupo se incluyeron de 20 a 23 mujeres jóvenes sedentarias evaluadas mediante el International Physical Activity Questionnaire (IPAQ), y la intervención se llevó a cabo durante 4 semanas. La prescripción del ejercicio se hizo previa determinación del VO2 pico por ergo espirometría, y su realización se monitoreó con sensores de frecuencia cardíaca. El efecto de la intervención se evaluó mediante los cambios en los niveles séricos de colesterol total (CT), colesterol LDL (cLDL), colesterol HDL (cHDL) y triacilgliceroles (TAG), tomados a las semanas cero, dos y cuatro. Resultados: En el grupo ®ejercicio a 65% del VO2 pico, más inclusión de leguminosas en la dieta¼ se obtuvieron los siguientes resultados significantes: una reducción promedio del colesterol total de 19.8 mg/dl (p=0.0015), del colesterol LDL de 21.8 mg/dl (p=0.0001), un aumento de colesterol HDL de 6.2 mg/dl (p=0.0001) y una disminución de los triacilgliceroles de 20.7 mg/dl (p=0.0001). En el grupo de sólo ejercicio a 65% del VO2 pico se obtuvo un aumento del HDL. No hubo modificaciones al perfil lipídico en el grupo correspondiente a sólo inclusión de leguminosas en la alimentación...

Phytochemical study and evaluation of the anti-inflammatory activity of some medicinal plants growing in Egypt

The anti-inflammatory activity of different extracts of five plants abundantly growing in Egypt, namely Ipomoea palmate Forsk. [Convolvulaceae], Alstonia scholaris R.Br. [Apocynaceae], Salix subserrata Willd., Salix tetrasperma Roxb, and Populus nigra Linn. [Salicaceae] has been studied. Phytochemical study on selected bioactive extracts was carried out as well as their possible mechanism of action. The results revealed a significant anti-inflammatory activity of the extracts under investigation to different degrees. A chromatographic study of the bioactive lipoidal extracts of A. scholaris and I. palmate was carried out and the results revealed the presence of unsaturated fatty acids [linoleic and linoleic]. Beta-sitosterol and campesterol were present in A. scholaris and I. palmate, respectively. Chromatographic and spectral investigation of the flavonoids in the bioactive aqueous extract of I. palmate revealed the presence of luteolin, quercetin 7-glycosie and apigenin. The anti-inflammatory activity may be due to the presence of these phytochemical constituents

Changes in the brain cholesterol level induced by different cholesterol derivatives in albino rats

Changes in the level of cholesterol in albino rats CNS [cerebrum, cerebellum, brain stem, spinal cord] were evaluated following the administration of three reported derivatives of cholesterol 3beta-acetoxy-cholest 5-ene, 3beta-acetoxy-6-nitro..cholest-5-ene and 3beta-acethxy-5-cholestan-6-one. Experiments were conducted on four groups of six albino rats weighing 250-300 gm. Control rats were administered normal saline ip while the other three experimental groups were given 0.3 mg/kg bw of steroidal solution ip which was prepared in peanut oil
