The metal-rich bulge globular cluster NGC 6388 shows a distinct blue horizontal-branch tail in its colour-magnitude diagram (Rich et al. 1997) and is thus a strong case of the well-known 2nd Parameter Problem. In addition, its horizontal branch (HB) shows an upward tilt toward bluer colours, which cannot be explained by canonical evolutionary models. Several noncanonical scenarios have been pro...

background: chronic abuse of opiates induces dependency, but the neurobiological mechanisms of this event remain unclear. the aim of this study was to evaluate the effects of intracerebroventricular of venlafaxine on the morphine dependence and pain perception. methods: a total of 80 adult male rats were divided into two major groups: (1) 40 of them was divided into groups of positive control (...

BACKGROUND Pre-cooling is known to enhance exercise performance in soccer players. However, little information currently exists regarding precooling effects in Iranian young soccer players. OBJECTIVES The aim of this study was to assess the effect of precooling (water immersion) on exhaustive performance in the heat ( temperature = 32 - 34°C, humidity = 50%). PATIENTS AND METHODS Sixteen yo...

Background and Aims: The object of this study was the investigation central antinociceptive effects naringin as well association stimulation opioidergic, serotonergic, adrenergic, cholinergic (muscarinic nicotinic) receptors to analgesia mice due naringin. Methods: Several intraperitoneal doses (20, 40, 80 mg/kg) were injected into models analyzed via hot-plate (integrated supraspinal response)...

Pelargonium species are native to South Africa, and they have a long history in medicinal use. This study aimed extract essential oils from different parts of P. peltatum, determine the chemical composition oils, assess oils’ biological potential as analgesic anti-inflammatory agents. The were obtained by hydro-distilling profile was determined GC-FID GC-MS. activity oil using tail immersion ho...

The seeds of Peganum harmala L. ( Pgh ) (Zygophyllaceae) have been used in Moroccan traditional medicine for treatment of a various diseases and to relieve dolorous process. The major objective of this paper was to investigate the analgesic effect of ethyl acetate (EAE), butanolic (BE) and aqueous (AqE) extracts of seeds of Peganum harmala and elucided the possible underlying action mechani...

BACKGROUND There are severe adverse effects of analgesic drugs on human body. Extraction of analgesic drugs from natural products has therefore become the prime objective of the study. In this study, we aimed to evaluate the antinociceptive activity of the pomegranate fruit. MATERIALS AND METHODS Antinociceptive activity of ethanol pomegranate extract was examined using three models of pain: ...

AIM To compare stress resistance increasing and analgesic activities of piperlongumine and a methanolic Piper longum fruit extract (PLE). METHODS Efficacies of a single and repeated daily oral doses (1-256 mg/kg/day) of PLE, piperlongumine, and 50 mg/kg/day doxycycline against foot shock stress triggered alteration in body weights and core temperatures, and of their 11 daily doses on antidepr...

The methanolic extract of the roots of Asparagus africanus Lam (Liliaceae) which contains mainly saponins and carbohydrate showed significant analgesic and anti-inflammatory activities (P<0.05) in the tail-flick/hot-plate test and egg albumen-induced rat paw oedema tests that were comparable to the test drugs (morphine 20 mg/kg and indomethacin 50 mg/kg respectively). These results indicate tha...

Hot bathing has been associated with sudden death and so the present study investigated its effects on autonomic activity and hemodynamics in the elderly patient and the healthy young by analyzing heart rate variability (HRV). Subjects were 9 elderly men (mean age, 75 years) and 9 young men (mean age, 27 years), who were immersed up to shoulder level while in a sitting position for 10min with t...
