ABSTRACT
Objective:To determine the relationship between brachia l artery blood pressure and radial artery blood pressure in children and whether blood pressure measured from the radial artery can replace blood pr essure measured from the brachial artery. Methods:Brachial and rad ial artery pressures in 105 children were measured using an electronic sphygmomanometer.Results:There was no significant difference between the average values of blood pressures of the brachial and radial arteries in the 105 children studied (P>0.05). Linear regression and correlation analyses showed that there was a positive linear correlation between the systolic pressure of the b rach ial artery and the radial artery in the 105 children, as well as a posit ive linear correlation between the diastolic pressures of the brachial and the radial arteries. Conclusion:Blood pressure values from the radial artery can completely replace blood pressure values from the brachial artery.
ABSTRACT
Objective To investigate the plasma level of free radicals and antioxidative activity in elderly patients with type 2 diabetes mellitus and relation to microvascular complication. Methods The concentration of erythrocyte lipoperoxides(LPO), plasma vitamin E(VE), plasma vitamin C(VC), plasma betacarotene(? CAR), whole blood glutathione(GSH) and the activity of erythrocyte superoxide dismutase(SOD), erythrocyte catalase (CAT), erythrocyte glutathione peroxidase(GSH PX) in 65 elderly patients with type 2 diabetes and 65 healthy patients were measured. Meanwhile, fasting glucose, 2 hours post meal glucose, glycated hemoglobin, fasting and post meal C peptide, triglycerides, cholesterol, urine albumin excretion rate, electromyogram were measured. Results Compared with the healthy patients, the average value of LPO(42 97?6 99)nmol/g and (31 59?7 44)nmol/g, VC (40 98?10 51)?mol/L and (52 23?10 51)?mol/L, VE (16 44?2 45)?mol/L and (23 04?5 38)?mol/L, ? CAR (1 19?0 23)?mol/L and (1 63?0 40)?mol/L and GSH(0 98?0 16 vs 1 25?0 20) in elderly patients with type 2 diabetes were significantly increased, while the activities of SOD(1712 44?157 04)U/L and (1 928 38?143 44)U/L, CAT(217 01?29 36)?g/g vs (264 40?63 55)?g/g, GSH PX(21 01?3 38)?10 -10 U/RBC vs (25 16?6 41)?10 -10 U/RBC were obviously decreased. The change was more obvious in the patients with microvascular complication compared with those without microvascular complication. Plasma level of LPO were correlated positively with age(r=0 310, P
ABSTRACT
Effects of opiate receptor blocker-naloxone ( 5mg/kg) on somatosensory evoked potentials ( SEP ) in 6 cats was studied. Other 6 cats were treated with normal saline as control. Results showed that the amplitudes of SEP were significantly elevated after 0.5h of aaloxone infusion. The changes of SEP-CCTp or CCTmn were no significant. It was suggested that large dosage of naloxone can favorably improve the electrical activites of neuron in the centre nerve system.
