Effect of garlic (Allium sativum) oil on exercise tolerance in patients with coronary artery disease.

The effect of six weeks garlic oil administration was observed on cardiac performance and exercise tolerance in 30 patients of coronary artery disease. After initial treadmill stress test, they were administered garlic oil in the dose of four capsules twice a day for 6 weeks and treadmill stress test was repeated. Garlic significantly (P<0.01) reduced heart rate at peak exercise and also significantly reduced the work load upon the heart resulting in better exercise tolerance (P<0.05) as compared to the initial test. It appears to be a good adaptogen to be utilized in patients with coronary artery disease.

Protective effect of ginger, Zingiber officinale Rosc on experimental atherosclerosis in rabbits.

The effects of air dried ginger powder (0.1g/kg body weight, po, for 75 days) were studied on experimentally induced atherosclerosis in rabbits by cholesterol feeding (0.3g/kg body weight, po). Cholesterol feeding for 75 days lead to distinct development of atheroma in the aorta and coronary arteriesof the rabbits and this was significantly inhibited by about 50% following ginger administration. There was distinct decrease in lipid peroxidation and enhancement of fibrinolytic activity in ginger treated animals. However, ginger did not lower blood lipidsto any significant extent. This distinct protection from the development of atherosclerosis by ginger is probably because of its free radical scavanging, prostaglandin inhibitory and fibri properties.

Ginger, fat and fibrinolysis.

Administration of 50 gm of fat to 30 healthy adult volunteers decreased fibrinolytic activity from a mean of 64.20 +/- 5.31 to 52.10 +/- 3.20 units (P < 0.001). Supplementation of 5 gm of ginger powder with fatty meal not only prevented the fall in fibrinolytic activity but actually increased it significantly (P < 0.001). This fibrinolytic enhancing property is a further addition to the therapeutic potential of ginger.

Effect of garlic (Allium sativum) on blood lipids, blood sugar, fibrinogen and fibrinolytic activity in patients with coronary artery disease.

Thirty patients with coronary artery disease (CAD) were administered garlic (study group) while another 30 patients received the placebo (control group). Various risk parameters were determined at 1.5 and 3 months of garlic administration. Garlic, administered in a daily dose of 2 x 2 capsules (each capsule containing ethyl acetate extract from 1 g peeled and crushed raw garlic), reduced significantly total serum cholesterol and triglycerides, and increased significantly HDL-cholesterol and fibrinolytic activity. There was no effect on the fibrinogen and glucose levels. In vitro effects of the garlic oil on platelet aggregation (PAg) and eicosanoid metabolism were examined; it inhibited PAg induced by several platelet agonists, and also platelet thromboxane formation. Two important paraffinic polysulphides - diallyl disulphide (DADS) and diallyl trisulphide (DATS) - derived from garlic and are usual constituents of garlic oil, showed antiplatelet activity, and also inhibited platelet thromboxane formation. In this respect DATS was more potent than DADS. The nature of inhibition of PAg by DATS was found to be reversible.

Antioxidant property of Saffron in man.

50 mg of Saffron dissolved in 100 ml of milk was administered twice a day to 20 human subjects. Lipoprotein oxidation susceptibility (LOS) was estimated initially and after 3 and 6 weeks. There was a constant decrease in LOS during this period. From a mean of 66.4 +/- 3.18 it decreased to 38.3 +/- 2.8 in 10 healthy individuals and from 76.0 +/- 3.72 to 48.8 +/- 3.0 in 10 patients of CAD. The significant fall (P < 0.001) in LOS indicates the potential of Saffron as an antioxidant.

Effect of ginger (Zingiber officinale Rosc.) and fenugreek (Trigonella foenumgraecum L.) on blood lipids, blood sugar and platelet aggregation in patients with coronary artery disease.

In a placebo-controlled study the effect of ginger and fenugreek was examined on blood lipids, blood sugar, platelet aggregation, fibrinogen and fibrinolytic activity. The subjects included in this study were healthy individuals, patients with coronary artery disease (CAD), and patients with non-insulin-dependent diabetes mellitus (NIDDM) who either had CAD or were without CAD. In patients with CAD powdered ginger administered in a dose of 4 g daily for 3 months did not affect ADP- and epinephrine-induced platelet aggregation. Also, no change in the fibrinolytic activity and fibrinogen level was observed. However, a single dose of 10 g powdered ginger administered to CAD patients produced a significant reduction in platelet aggregation induced by the two agonists. Ginger did not affect the blood lipids and blood sugar. Fenugreek given in a dose of 2.5 g twice daily for 3 months to healthy individuals did not affect the blood lipids and blood sugar (fasting and post prandial). However, administered in the same daily dose for the same duration to CAD patients also with NIDDM, fenugreek decreased significantly the blood lipids (total cholesterol and triglycerides) without affecting the HDL-c. When administered in the same daily dose to NIDDM (non-CAD) patients (mild cases), fenugreek reduced significantly the blood sugar (fasting and post prandial). In severe NIDDM cases, blood sugar (both fasting and post prandial) was only slightly reduced. The changes were not significant. Fenugreek administration did not affect platelet aggregation, fibrinolytic activity and fibrinogen.

Effect of garlic on platelet aggregation in humans: a study in healthy subjects and patients with coronary artery disease.

Garlic's value in preventing cardiovascular disease has been reported by several research groups. Garlic and its components are known to possess antiplatelet activity which has been demonstrated mostly in vitro. It was found that garlic oil administration to healthy subjects and patients with coronary artery disease (CAD) inhibited platelet aggregation ex vivo. Though garlic components leave the body quickly, a slow build-up of the active ingredients may take place. This was evident from the observation that though a 2-3 fold higher dose was not effective in inhibiting platelet aggregation when administered once, a lower dose became effective in long-term administration.

Radio-protective effect of garlic Allium sativum Linn. in albino rats.

S-allyl cysteine sulphoxide (SACS), a sulphur containing aminoacid of garlic is the precursor of allicin and garlic oil, and has been found to show significant radio protective effect in albino rats which were whole body irradiated with 400 rads of irradiation by Cobalt 60 source. It markedly reduced the radiation induced mortality and showed significant protection against the tissue damaging effects of irradiation in histopathological sections of liver and lung.

Curcumin, a major component of food spice turmeric (Curcuma longa) inhibits aggregation and alters eicosanoid metabolism in human blood platelets.

In traditional medicine, Ayurveda, several spices and herbs are held to possess medicinal properties. Earlier we have reported that extracts from several spices, including turmeric, inhibit platelet aggregation and modulate eicosanoid biosynthesis. Due to their eicosanoid-modulating property, it was suggested that the spices may serve to provide clues to drugs directed to arachidonic acid (AA) pathway enzymes as pharmacological targets. Curcumin, a major component of turmeric, inhibited platelet aggregation induced by arachidonate, adrenaline and collagen. This compound inhibited thromboxane B2 (TXB2) production from exogenous [14C] arachidonate in washed platelets with a concomitant increase in the formation of 12-lipoxygenase products. Moreover, curcumin inhibited the incorporation of [14C]AA into platelet phospholipids and inhibited the deacylation of AA-labelled phospholipids (liberation of free AA) on stimulation with calcium ionophore A23187. Curcumin's anti-inflammatory property may, in part, be explained by its effects on eicosanoid biosynthesis.

The hypoglycemic effect of chloroquine.

Ten persons were studied to observe the effect of intravenous administration of chloroquine on serum glucose level. Ten healthy individuals were given 800 mg of chloroquine in three hours infusion. There was a significant (p = 0.001) fall of 25.86 per cent of initial blood glucose level in test group, while it was only 10.47 per cent in control group. Therefore, it is emphasized that seriously III patients and those who are prore to hypoglycemia should be carefully monitored when giving IV chlorquine.

Effect of ginger on platelet aggregation in man.

Dietary supplementation of 100 g butter in 20 healthy male volunteers for 7 days was found to enhance platelet aggregation to a significant extent (P < 0.001). Addition of 5 g of dry ginger in two divided doses with fatty meal (in 10 individuals) significantly (P < 0.001) inhibited the platelet aggregation induced by ADP (adenosine diphosphate) and epinephrine, while in the placebo control group (10 individuals), there was no significant alteration in platelet aggregation. Serum lipids, however, remained unchanged in both the groups.

Effect of intravenous infusion of verapamil in patients of severe hypertension.

Thirty patients with diastolic blood pressure of 120 mm Hg or more were administered a bolus dose of verapamil (0.15 mg/kg) followed immediately by an intravenous infusion at a rate of 0.005 mg/kg/min for one hour. The patients were monitored during this period and three hours following the discontinuation of the infusion. The systolic, diastolic and mean blood pressures before verapamil administration were 221.4 +/- 7.5, 134.3 +/- 2.7 and 163.4 +/- 4.1 mm Hg respectively, which decreased to 170.1 +/- 5.2, 99.1 +/- 3.7 and 122.8 +/- 3.6 mm Hg after intravenous bolus of verapamil. The fall in all the levels of blood pressure was significant (p less than 0.001) and was maintained at the lower levels throughout the infusion period and even three hours after discontinuation of the therapy. No untowards effects were observed and there was no significant change in heart rate and electrocardiogram. It, thus, proves to be an useful addition to the therapeutic armamentarium in the acute management of severe hypertension.

Effect of vitamin C on platelet adhesiveness and platelet aggregation in coronary artery disease patients.

The effect of oral administration of vitamin C on platelet adhesive index (PAI), platelet aggregate ratio (PAg R) and serum ascorbic acid levels was studied. Feeding 75 g of butter to healthy males (group I, n = 10 cases), enhanced the tendency of platelet adhesiveness (PAd) and platelet aggregation (PAg) to a significant level at the end of 4 h. This was distinctly prevented when 1 g of vitamin C was added to the fatty meal. In coronary artery disease (CAD) patients (group II, n = 20 cases) 10 days of vitamin C administration at 1 g every 8 hours decreased the PAd (p less than 0.001) and PAg (p less than 0.05) significantly. There was also a significant (p less than 0.001) rise in the vitamin C levels. The study brings out a property of vitamin C which may be of considerable importance in prevention of chronic thromboatherosclerotic disease of the arteries.

Effect of garlic on blood lipids in patients with coronary heart disease.

The study was conducted on two groups of individuals. Group A consisted of 20 healthy volunteers who were fed garlic for 6 months and then followed for another 2 months without garlic. Garlic administration significantly lowered the serum cholesterol and triglycerides while raising the high-density lipoproteins. Group B consisted of 62 patients with coronary heart disease with elevated serum cholesterol. They were randomly divided into two subgroups: B1 was fed garlic for 10 months while B2 served as a control. Garlic decreased the serum cholesterol (p less than 0.05), triglycerides (p less than 0.05) and low density lipoprotein (p less than 0.05) while increasing the high-density fraction (p less than 0.001). The change reached statistically significant levels at the end of 8 months and persisted for the next 2 months of follow-up. Thus, the essential oil of garlic has shown a distinct hypolipidemic action in both healthy individuals and patients of coronary heart disease.

Effect of garlic feeding on regression of experimental atherosclerosis in rabbits.

Thirty six rabbits were fed a cholesterol-containing diet for 3 months to produce atherosclerosis. Twelve rabbits were killed at the end of this period for baseline observations (Group I). The remaining animals were divided into two groups; Group II was fed stock diet and Group II was fed essential oil of garlic added to the stock diet. All the animals were killed at the end of 12 months. Blood lipids and fibrinolysis were monitored during the progression and regression phases. After cholesterol feeding was discontinued, serum total cholesterol and triglyceride concentration decreased gradually in both the groups. However, there was an increase in HDL levels in the garlic fed groups. Cholesterol feeding resulted in 80.9% atheromatous involvement of aortic surface in Group I. This remained almost the same (71.1%) after 9 months of stock feeding (Group II) while in the garlic fed group only 30.4% of the aortic surface had lesions. Correspondingly, the aortic lipid content of garlic fed animals was reduced by 72%, while in the control group there was no significant reduction. The data suggests that cholesterol is depleted from experimentally induces atherosclerosis by garlic administration.
