background: objective: the aim of this study was to investigate the effects of aqueous and hydro-alcoholic extracts of lettuce seed on testosterone level and spermatogenesis. materials and methods: in this experimental study 24 adult male nmri mice weighing 20-25gr were purchased. animals were randomly divided into 4 groups: controls, hydro-alcoholic (200 mg/kg) and aqueous extracts (50, 10...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
Membrane extraction has been interfaced with gas chromatography and mass spectroscopy for the analysis of volatile organics in water. The vacuum in a mass spectrometer provides fast mass transport. The time required to complete permeation in a GC interface can be fairly long, because the positive pressure of the carrier gas on the permeate side slows down the analyte permeation. The aqueous bou...
Determination of intraocular antibody synthesis against certain microorganisms is a diagnostic aid in identifying the causative agent in clinical uveitis. Little is known, however, concerning the kinetics and specificity of antibodies produced during intraocular inflammation. To investigate this subject we induced uveitis in rabbits by injecting small amounts of human serum albumin (HSA) into t...
The sustained and moderate elevation of intraocular pressure, which can be initiated at precise time points, remains the cornerstone of research into the mechanisms of glaucomatous retinal damage. We focus on the use of microbeads to block the outflow of aqueous following anterior chamber injection in a range of animals (mouse, rat and primate). We describe some of the most commonly used parame...
the aqueous extract of syzygium cumini (pulp) was investigated for its possible hypoglycemic and antioxidant potentials in streptozotocin (stz) induced diabetic wistar female rats. a single intraperitoneal injection of stz at a dose of 55 mg/kg body weight elevated the glucose levels more than 230 mg/dl after 3 days. treatment with the aqueous extract of syzygium cumini (pulp) at 100 mg/kg and ...
Background: The study was aimed to evaluate the anti-inflammatory activity of ethanolic and aqueous extracts of Polygonum minus (Huds) using in vitro and in vivo approaches. Methods: The in vitro tests used to evaluate ethanolic extract are cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), lipooxygenase (5-LOX), secretory phospholipase-A2 (sPLA2) inhibition assay whilst the in-vivo effect was...
The medicinal plant Olea europaea L. is a valuable one whose fruit and its oil are considered as food. There are some reports in ancient medical literature that aqueous extract of its leaves has analgesic effects. This prompted us to investigate the analgesic effect of aqueous extract of its leaves using formalin and tail-flick tests. For this purpose, male NMRI rats weighting 220-260 g were us...
In order to examine the uptake of L-serine into brain structures and brain metabolic compartments, L-[U-14C]serine was injected into tail vein of mice. The uptake was examined 30 min, 90 min, 3 h and 5 h after injection by both quantitative autoradiography of coronal brain sections and by biochemical analysis. Brain radioactivity was extracted and partitioned into protein associated pellets, me...
PURPOSE To evaluate the effect of 8-bromo cGMP (Br cGMP) on aqueous humor flow rate and outflow facility in monkey eyes. METHODS. Aqueous humor flow rate was measured fluorophotometrically after topical, intracameral, or intravitreal administration of Br cGMP in one eye and normal saline in the other eye. Outflow facility was determined by two-level constant pressure perfusion after intracamera...
