Effect of Ubiquinol on Serum Reproductive Hormones of Amenorrhic Patients.

In neuroendocrine system the increase in oxidative status is produced by a glucocorticoid-dependent and transcriptional increase in pro-oxidative drive, with concurrent inhibition of the antioxidant defense system, ultimately leading to increased neuronal cell death. Functional hypothalamic disturbances and neuroendocirne aberrations have both short and long term consequences for reproductive health. Understandably, an impaired or diminished hypothalamic-pituitary-ovarian axis leads to anovulation and hypoestrogenism. Anovulation is directly linked to the neurohormonal and hormonal background of Functional Hypothalamic Amenorrhea. Impairment of pulsatile Gonadotropin Releasing Hormone secretion causes the impairment of pulsatile Lutenizing Hormone (LH) and Follicle Stimulating Hormone (FSH) secretion. The importance of oxidative stress in various pituitary disorders suggesting a possible clinical usefulness of antioxidant molecules like the lipophilic antioxidant Ubiquinol. Coenzyme Q10 or Ubiquinol is an essential part of the cell energy-producing system of mitochondria. However, it is also a powerful lipophilic antioxidant, protecting lipoproteins and cell membranes from autooxidation. Due to these unique actions Ubiquinol is used in clinical practice as an antioxidants for neurodegenerative diseases. So to identify the role of Ubiquinol on reproductive hormones FSH and LH, we have included 50 infertile patients of age group of 20-40, which are mostly amenorrhic. Out of 50 only 30 patients were in continuous follow up after supplementing them with 150 mg of Ubiquinol every day for 4 months. The hormonal levels were estimated by Enzyme Linked Immuno Sorbent Assay technique at follicular phase. The result suggests that FSH concentration is increased up to three times (from 3.10 ± 2.70 to 10.09 ± 6.93) but remains within the normal limit (P < 0.05). LH values were found doubled (P < 0.05) than its normal range (from 14.83 ± 10.48 to 27.85 ± 22.30). The Prolactin values were decreased while Progesterone values were high but not in the significant range (P > 0.05). The supplementation of 150 mg of Ubiquinol may reduce the oxidative stress in neuroendocrine system which further improves the function of diminished HPA axis. Hence increased level of FSH and LH may be due to reduced oxidative stress by Ubiquinol.

Hematological Parameters and RBC TBARS Level of Q 10 Supplemented Tribal Sickle Cell Patients: A Hospital Based Study.

The study has been undertaken as number of sickle cell patients in Chhattisgarh tribal population is 23.7 %. The Co enzyme Q10 is a strong antioxidant and energy producing compound. The patients were divided into three groups group A homozygous (SS), group B heterozygous (AS) and group C controls for TBARS study. The age group is 10-55 years and 200 mg of CoQ10 was given to A and B groups. The hematological parameters, C reactive protein as well as RBC TBARS level were performed by usual and standard techniques. The results were obtained as 25.37 % increased RBC level in group A and 23.24 % in group B. The increased hemoglobin level was observed as 16.73 % in group A and 10.7 % in group B. In case of WBC it was observed increased 24.38 % in group A and 12.0 % in group B. C-reactive protein was observed 7.8 times decreased in group A and 1.54 times in group B. The RBC TBARS level was also found decreased 48 % in group A and 51 % in group B as compared to group C. During the supplementation of coenzyme Q10 the pain caused by vaso-occlusive events has reduced. This significant increase in hematological parameters as well as decreased C-reactive protein and TBARS level suggest that the Q10 should be included in the diet of sickle cell patients.

Development and validation of a scale measuring the locus of control orientation in relation to socio-dental effects.

AIM: To develop a socio-dental impact locus of control scale (SILOC) and to study its relationship with oral health status as well as dental attendance. STUDY DESIGN: Observational cross-sectional study design. METHOD: A seven-item SILOC scale based on locus of control and the WHO international classification of diseases' criteria for "Disability" in relation to oral health was developed. In the pilot study, 100 adolescent school children returned completed forms containing the multidimensional health locus of control (MHLC) and the (SILOC) scale. After confirmation of reliability and validity, 509 adolescent school children returned completed SILOC questionnaires and were examined for caries, plaque and gingivitis. A history of postponement of needed dental treatment was also elicited. RESULTS: The SILOC scores were highly correlated with the MHLC scores. Factor analysis revealed a two-factor solution accounting for 59 % of the variance. A Cronbach's alpha of 0.75 showed its internal consistency. Those with higher SILOC scores had greater levels of caries, plaque, gingivitis, and a history of postponing needed dental visits. Multiple logistic regression analysis after adjusting for potential confounders showed that those with high SILOC scores were more likely to have caries (OR = 3.32, p < 0.001), plaque (OR = 1.83, p = 0.026), gingivitis (OR = 1.80, p = 0.012) and a history of 'Postponement of needed dental treatment' (OR = 4.5, p < 0.001) as compared with the others. CONCLUSIONS: The SILOC scale showed satisfactory reliability and validity in measuring locus of control orientation in an Indian adolescent population.

Effect of coenzyme Q10 on experimental atherosclerosis and chemical composition and quality of atheroma in rabbits.

The effects of the administration of coenzyme Q10 (3 mg/kg per day) (group A, n=10) and placebo (aluminum hydroxide, 3 mg/kg per day) (group B, n=10) were compared over 24 weeks in a randomized, single-blind, controlled trial. There were two groups of rabbits receiving a trans fatty acid (TFA)-rich diet (5-8 g/day) for 36 weeks. Oxidized rabbit chow with vitamin C plus ferric chloride was administered for 4 weeks in all rabbits. Intervention with coenzyme Q10 after feeding of TFA-rich diet was associated with a significant decline in thiobarbituric acid reactive substances (TBARS), diene conjugates and malondialdehyde, and an increase in plasma levels of vitamin E in the coenzyme Q group compared to placebo group. These changes, which were indicators of a decrease in oxidative damage, were independent of lipid lowering. The aortic and coronary artery plaque sizes, coronary atherosclerosis index, aortic and coronary atherosclerosis scores were significantly lower in the coenzyme Q group than placebo group. Aortic and coronary plaque frequencies, as well as frequencies of ulceration, thrombosis or hemorrhage, and cracks and fissures, were also significantly lower in the coenzyme Q group, indicating a better quality of atheroma compared to those in the control group. Aortic cholesterol, triglycerides and sudanophilia were significantly lower and vitamin E significantly higher in the coenzyme Q group in comparison to the placebo group indicating that coenzyme Q10 can have beneficial effect on the chemical composition of atheroma. The findings suggest that antioxidant therapy with coenzyme Q10 may be used as an adjunct to lipid lowering for additional beneficial effects related to chemical composition and quality of atheroma independent of hypolipidemic agents.

Effect of hydrosoluble coenzyme Q10 on blood pressures and insulin resistance in hypertensive patients with coronary artery disease.

In a randomised, double-blind trial among patients receiving antihypertensive medication, the effects of the oral treatment with coenzyme Q10 (60 mg twice daily) were compared for 8 weeks in 30 (coenzyme Q10: group A) and 29 (B vitamin complex: group B) patients known to have essential hypertension and presenting with coronary artery disease (CAD). After 8 weeks of follow-up, the following indices were reduced in the coenzyme Q10 group: systolic and diastolic blood pressure, fasting and 2-h plasma insulin, glucose, triglycerides, lipid peroxides, malondialdehyde and diene conjugates. The following indices were increased: HDL-cholesterol, vitamins A, C, E and beta-carotene (all changes P<0.05). The only changes in the group taking the B vitamin complex were increases in vitamin C and beta-carotene (P<0.05). These findings indicate that treatment with coenzyme Q10 decreases blood pressure possibly by decreasing oxidative stress and insulin response in patients with known hypertension receiving conventional antihypertensive drugs.

Social class and coronary artery disease in a urban population of North India in the Indian Lifestyle and Heart Study.

OBJECTIVE: To determine the association of social class with prevalence of coronary risk factors and coronary artery disease (CAD). DESIGN AND SETTING: Total community cross sectional survey of 20 randomly selected streets in the city of Moradabad. SUBJECTS AND METHODS: 1806 urban (904 men and 902 women) randomly selected subjects aged 25-64 years. The survey methods were physician and dietitian administered questionnaire, physical examination and electrocardiography. All subjects were divided into social classes 1-5 based on attributes of education, occupation, per capita income, housing condition and consumer durables and other family assets. RESULTS: Social classes 1, 2 and 3 were mainly high and middle socioeconomic groups and 3 and 4 low income groups. The prevalence of CAD and coronary risk factors hypercholesterolemia, hypertension, diabetes mellitus and sedentary lifestyle were significantly higher among social classes 1, 2 and 3 in both sexes compared to lower social classes. Mean serum cholesterol, triglycerides, low density lipoprotein cholesterol and blood pressure were significantly associated with higher and middle social classes. Smoking was significantly associated with lower social classes. Multivariate logistic regression analysis after adjustment of age revealed that social class was positively associated with CAD (odds ratio: men 0.84, women 0.86), hypercholesterolemia (men 0.87, women 0.85), hypertension (men 0.91, women 0.89), diabetes mellitus (men 0.71, women 0.68) and sedentary lifestyle (men 0.68, women 0.66). Smoking was significantly associated with CAD in men. CONCLUSION: Social class 1, 2 and 3 in an urban population of India have a higher prevalence of CAD and coronary risk factors hypercholesterolemia, hypertension, diabetes mellitus and sedentary lifestyle in both sexes.

Prevalence and risk factors of hypertension and age-specific blood pressures in five cities: a study of Indian women. NKP Salve Institute of Medical Sciences, Nagpur, India. Five City Study Group.

OBJECTIVE: To measure the prevalence of hypertension and age-specific blood pressure in urban populations from five Indian cities. Cross-sectional surveys were conducted in six-twenty urban streets in different cities from five different corners of India, using similar methods of sample selection and criteria. There were 3212 randomly selected women from Moradabad (n=902), Trivandrum (n=760), Calcutta (n=365), Nagpur (n=405) and Bombay (n=780), aged 25-64 years, inclusive. Evaluation was by a physician and a dietitian, an administered questionnaire, a physical examination and using a sphygmomanometer. The diagnosis of hypertension was based on old World Health Organisation criteria and new World Health Organisation/International Society of Hypertension criteria. The prevalence of hypertension (>140/90 mm Hg) was significantly (P<0.01) high in Trivandrum, South India (30.7%), and Bombay, West India (28.0%), compared to Moradabad, which is in northern India (22.6%), Nagpur, in central India (24.2%), and Calcutta, in east India (19.1%). Mean systolic and diastolic blood pressures were significantly higher in Trivandrum and Bombay compared to the other three cities. The overall prevalence of hypertension was 25.6% (n=823) and isolated diastolic hypertension was the most common form of hypertension (50.5%, n=1506) in the five Indian cities. According to old criteria, the overall prevalence of hypertension (>160/95 mm Hg) was 14.8% (n=481). Multivariate logistic regression analysis on pooled data from the five cities, after adjustment for age, showed that age (odds ratio 1.16), body mass index (1.68) and obesity were strongly associated with hypertension. A sedentary lifestyle and salt intake were weakly associated and alcohol intake was not a factor with these women.

Levels of erythrocyte malonyldialdehyde, vitamin E, reduced glutathione, G6PD activity & plasma urate in patients of pregnancy induced hypertension.

To assess the oxidative stress across the cell membrane in patients suffering from pregnancy induced hypertension, erythrocyte malonyldialdehyde, vitamin E, reduced glutathione, glucose-6-phosphate dehydrogenase activity and plasma urate levels were estimated in 25 non pregnant women, 40 normotensive pregnant women and 40 women with pregnancy induced hypertension (PIH). As compared to non pregnant women, there was a significant increase in the levels of erythrocyte malonyldialdehyde and plasma urate in normotensive pregnant women, which were further increased in women with PIH. Erythrocyte glutathione levels were raised in normotensive pregnant women as compared to non pregnant women. Its levels were decreased in patients of PIH as compared to normotensive pregnant women. Cellular bio-availability of vitamin E was depressed in both normotensive pregnancy as well as patients with pregnancy induced hypertension as compared to non pregnant women.

Rate of infection and of reinfection by Echinococcus granulosus in rural dogs of the province of Rio Negro, Argentina.

Hydatidosis (cystic echinococcosis) constitutes a serious public health problem in the Province of Rio Negro, Argentina. In the present work it was intended to evaluate the prevalence of the canine echinococcosis in rural areas of the Province of Rio Negro and studied the reinfection rate in dogs after treatment with Praziquantel during the period 1980-1997. A total of 496 dogs were studied in 18 canine concentrations in order to establish the initial prevalence rate which was 42.3%. From 1980 onward dogs should have been systematically treated with anthelmintic every 2 months in rural areas and every 6 months in urban areas. We estimated that approximately 65% of dogs were treated. To determine the reinfection rate, 476 dogs (1984) and 598 dogs (1996) were studied after anthelmintic treatment during two sequential time periods (0-45; 46-90 days). In both cases treated animals were compared with untreated dogs. Prevalences were 3.5%, 6.7% and 21.3% in 1984 and 0.8%, 4.0% and 10.0% in 1996. For the purpose of surveillance a total number of 21,444 dogs were studied during 18 years. Prevalence of Echinococcus granulosus decreased significantly in the first year from 42.3% to 6.1%.

Efficacy of droncit against Echinococcus granulosus infection in dogs.

A study was made on 120 dogs to evaluate the effectiveness of droncit against Echinococcus granulous infection. The drug was administered orally in tablet form at dose rates of 1.25, 2.5, 5.0,and 10.0 mg/kg of body weight against immature stages of the parasite and at a dose rate of 5.0 mg/kg against gravid worms. Droncit was found to be 100% effective against both immature and gravid worms at the dose rate of 5.0 mg/kg. Adverse reactions were not observed in the treated dogs, and no risk was involved in administering the drug. The use of droncit in hydatidosis control programs in discussed.

Carotid cavernous sinus fistula presenting with pulsating exophthalmos and secondary glaucoma.

Carotid cavernous sinus fistula is abnormal communications between the carotid arterial system and the venous cavernous sinus. Carotid cavernous sinus fistula can develop either because of trauma or spontaneous causes. Spontaneous carotid cavernous sinus fistula is often associated with a pre-existing aneurysm in the intracavernous portion of internal carotid artery. However, these fistulas may be congenital arteriovenous connections that open spontaneously in the settings of collagen vascular disease, atherosclerosis, hypertension, or may develop in females during peripartum period. A case of spontaneous carotid cavernous sinus fistula in a young adult male who presented with pulsating exophthalmos and secondary glaucoma is presented. Characteristic features of arteriovenous fistula--bruit, thrill, corkscrew episcleral vessels were present. Radiological investigations were done to confirm the diagnosis. Transvenous embolisation was done to close the fistula.

Body fat percent by bioelectrical impedance analysis and risk of coronary artery disease among urban men with low rates of obesity: the Indian paradox.

OBJECTIVE: To determine the association between body fat percent and prevalence of coronary artery disease (CAD) and coronary risk factors in subjects with low rates of obesity. SUBJECTS AND METHODS: We randomly selected 850 men, aged 25 to 64 years. The survey methods were questionnaire and bioelectrical impedance analysis for body composition. Subjects were divided into high-fat (n = 357), over-fat (n = 230), normal-fat (n = 200) and under-fat (n = 63) based on criteria of body-fat percent analysis. RESULTS: The prevalence of CAD and the coronary-risk factors hypercholesterolemia, hypertension, diabetes, mellitus and sedentary lifestyle were significantly associated with high and moderate body fat percent despite low body-mass index (23.6+/-4.1 kg/m2). Mean total cholesterol, triglycerides and blood pressure were significantly associated with high and moderate body fat percent. The prevalence of smoking was weakly but inversely associated with high body-fat percent. Mean HDL cholesterol was positively associated with high body-fat percent. Body mass index was positively associated with high body-fat percent. CONCLUSIONS: High and moderate body-fat-percent subjects were associated with high prevalence of CAD and the coronary-risk factors hypertension, diabetes mellitus, higher body-mass index and sedentary lifestyle.

Prevalence and determinants of central obesity and age-specific waist:hip ratio of people in five cities: the Indian Women's Health Study.

OBJECTIVE: To study the prevalence of central obesity and age-specific waist:hip ratio of urban women from five Indian cities. DESIGN AND SETTING: Cross-sectional surveys were conducted in 6-12 urban streets in different parts of India using similar methods of sample selection and criteria of diagnosis. SUBJECTS AND METHODS: We randomly selected 3212 women, aged 25-64 years, from Moradabad (n = 902), Trivandrum (n = 760), Calcutta (n = 365), Nagpur (n = 405), and Bombay (n = 780). Evaluation was by a questionnaire administered by a physician and a dietician, a physical examination, and anthropometric measurements. RESULTS: The overall prevalence of central obesity among the total number of women was 55.0%, with the highest prevalence in Calcutta (62.2%) and the lowest in Bombay (47.4%). Waist:hip ratio was 0.85 +/- 0.13 (mean +/- SD) with the highest ratio for women in Calcutta (0.87 +/- 0.12) and the lowest for women in Moradabad (0.84 +/- 0.16). After pooling of data from all five cities, multivariate logistic regression analysis showed that, regardless of age, body mass index (> 23 kg/m2; odds ratio 1.12), sedentary lifestyle (odds ratio 2.51), and family history of obesity (odds ratio 2.15) were strongly associated with central obesity. Excess intake of fat was weakly associated with central obesity but age was not a risk factor for central obesity, although the prevalence was highest among those aged over 55 years in Moradabad, Calcutta, and Nagpur. CONCLUSIONS: The overall prevalence of central obesity among the urban women of India has increased, more so in Calcutta and Trivandrum. Body mass index, sedentary lifestyle, and family history of excess intake of fat were significant risk factors for central obesity.
