A pharmacological and toxicological biochemical study of cardiovascular regulatory effects of hibiscus, corn silk, marjoram, and chamomile

Hypertension is one of the most typical causes of morbidity and mortality. The present study investigated the possible antihypertensive cardiovascular effects of an herbal mixture extract of Hibiscus, Corn silk, Marjoram, and Chamomile. HPLC analysis of the water extract prepared from the aerial parts of four plants and their mixture was done to detect the most predominant compounds. A safety study was done prior to the efficacy study to determine the dose and ensure the extract's safety in female rats. Hypertension was induced in ovariectomized and non-ovariectomized rats by oral administration of 50 mg/kg of LName for 30 days; the hypertensive rats were classified into non-ovariectomized and ovariectomized untreated groups, treated groups with high and low doses of the mixture(150,300 mg/kg) given to ovariectomized and non-ovariectomized hypertensive groups and a standard group treated with angiotensin-converting enzyme inhibitor. The untreated group showed significant elevation of blood pressure, heart rate, cholesterol, triglycerides, malondialdehyde, cyclic adenosine monophosphate, angiotensin-converting enzyme, C-reactive protein, and significantly lowered reduced glutathione, high-density lipoprotein, and endothelial nitric oxide synthase. Treatment significantly counteracted the effects of L Name. The mixture provides a promising natural cardiovascular regulating supplement owing to its high contents of flavonoids.

Evaluation of serum beta-endorphin and substance P in knee osteoarthritis patients treated by laser acupuncture

Background Laser acupuncture is one of the complementary modalities used for treating osteoarthritis. The study was performed to evaluate the effectiveness of laser acupuncture in the treatment of grade 2 knee osteoarthritis. Patients and methods Forty patients having bilateral knee osteoarthritis were divided into two groups (20 patients in each group). The patients of the first group were subjected to 12 laser sessions at the following acupoints (St 35, St36, Sp9, Sp10 and Gb 34). During each session, laser of 90 mw was directed to each acupoint for 1 min giving energy of 5.4 joules. Energy of 21.6 joules was directed to ashi points. The laser had a wavelength of 808 nm, beam diameter 2 mm and was applied with a continuous wave. The cases of the second group were used as controls. Each patient is exposed to sham laser (laser probe is directed to the same acupoints while the device is off). Results The 20 patients receiving laser showed significant improvement in pain on (VAS), increase in serum beta-endorphin and a decrease in substance P more than those exposed to sham laser. Conclusions Laser acupuncture is a safe and cheap tool for management of grade 2 knee osteoarthritis.

Comparison of Three Protocols: Dietary Therapy and Physical Activity, Acupuncture, or Laser Acupuncture in Management of Obese Females

AIM: The aim of this study was to compare efficiency of three types of obesity management protocols: dietary measures and physical activity; acupuncture or laser acupuncture with   healthy diet among obese females.SUBJECTS AND METHODS: Randomized longitudinal prospective study, carried out on 76 adult females. Blood pressure, anthropometric, ultrasonographic and biochemical assessments were done.RESULTS: Females undergo nutritional intervention showed highly significant improvement in the anthropometric measurements, visceral fat at umbilicus by US and diastolic blood pressure (decreased), and insignificant differences in fasting blood sugar and lipid profile. Female undergo acupuncture intervention showed highly significant improvement in visceral fat by US, lipid profile (decreased triglycerides, total cholesterol and LDL, and increased HDL), and decreased fasting blood sugar, and insignificant differences in the anthropometric measurements. Those undergo laser intervention showed highly significant improvement in all anthropometric measurements under study, visceral fat at umbilicus by US, blood pressure and some parameters of lipid profile (decreased total cholesterol and LDL). CONCLUSIONS: Nutritional intervention alone could be used to reduce weight if the lipid profile within normal range, but if it is impaired, acupuncture should be used beside. To strength the reduction in body anthropometry, laser intervention was recommended beside the nutritional intervention.
