1. The effects of chlorpromazine on sympathetic neuroeffector transmission have been studied in the rabbit isolated pulmonary artery and aorta. 2. Chlorpromazine (10(-8)-10(-5) M), prazosin (10(-9)-10(-7) M) and phentolamine (3 x 10(-8)-3 x 10(-5) M) decreased the contractions of pulmonary artery evoked by electrical field stimulation (150 pulses; 3 Hz). The rank order of inhibitory potency (ID...

Channel catfish Ictalurus punctatus fingerlings were fed purified diets supplemented with iron at levels of 0, 20, 60, and 180 mgkg from iron sulfate (FeS) or 5, 10, 20, 60, and 180 mgkg from iron methionine (FeM) in triplicate tanks for 8 wk. Fish were then divided into two groups and subjected to different assays to measure disease resistance and individual immune functions. Representative fi...

Neuromuscular blockade with pancuronium and its antagonism was evaluated in 33 critically ill infants. The evoked contraction of the adductor pollicis from indirect stimulation of the ulnar nerve was measured. The neuromuscular blockade recovered spontaneously from pancuronium in seven infants, 23 required one or more doses of atropine 0.02 ng kg-1 and neostigmine 0.06 mgkg-1. In three infants ...

Microbial consortia isolated from aged oil-contaminated soil were used to degrade 16 polycyclic aromatic hydrocarbons (15.72 mgkg(-1)) in soil and slurry phases. The three microbial consortia (bacteria, fungi and bacteria-fungi complex) could degrade polycyclic aromatic hydrocarbons (PAHs), and the highest PAH removals were found in soil and slurry inoculated with fungi (50.1% and 55.4%, respec...

We aimed to evaluate macrophages heterogeneity and structural, functional and inflammatory alterations in rat kidney by aldosterone + salt administration. The effects of treatment with spironolactone on above parameters were also analyzed. Male Wistar rats received aldosterone (1 mgkg-1d-1) + 1% NaCl for 3 weeks. Half of the animals were treated with spironolactone (200 mg kg-1d-1). Systolic an...

Saemund and Dalcnius reported five cases of nodal rhythm directly related to the injection of pancuronium 0.1 mgkg" •. We, too, have witnessed several examples of transient nodal rhythm after the administration of pancuronium and not infrequently this rhythm disturbance has been accompanied by a decrease in arterial pressure. Recent reviews (PrysRoberts, 1981) emphasize the potential deleteriou...

Deltamethrin is a broad-spectrum insecticide mainly used to protect crops, fruit and vegetables from mites, ants, weevils, beetle etc. Thus deltamethrin contaminated food of commercial poultry diet may cause toxic effects in broilers and indirect adverse effects on human through food chain. Therefore, hematological and biochemical alterations in White Leghorn birds due to deltamethrin induced t...

We investigated the influence of soil properties on availability or otherwise micronutrients in agricultural soils impacted by inorganic and organic manures South-South Area Nigeria. The levels pH, matter (OM), cation exchange capacity (CEC), copper (Cu), iron (Fe), manganese (Mn), zinc (Zn) understudy were examined. measured OM, CEC, Cu, Fe, Mn Zn revealed: 6.04±0.49, 17.68±4.78 %, 7.97±0.81 C...

Fifty one soil samples werecallected from some wadis i.e.,(El Sheikh Soliman,Sidri,El-Arishia and Bodra) of AduRudeis district, which is lies between mountain chains. These were collected to determined their physical chemical properties assess total available contents Fe, Mn, Zn Cu in a fairly intanse sampling scheme.The results indicate that the texture class varies sandy clay loam, The conten...

Aims: This study was aimed at investigating the protective potential of ethyl acetate fractions Persea americana (PA) seed and Bryophyllum pinnatum (BP) leaf binary combinations against indomethacin-induced gastric ulcers.
 Methodology: Fifty (50) male Wistar rats were used in this study; they assigned into 10 groups five animals each respective received a standard rat diet drinking water ...
