noise is considered as one of the most severe sources of environmental and work place constraints. noise effects on immune function, hormonal levels, cardiovascular and respiratory systems are well known. the aim of the study is to evaluate the effects of traffic noise on basal and stimulated gastric acid secretion. 48 healthy rats were divided into five traffic noise exposures (1, 7, 14, 21, 2...

The statistics pertaining to heart failure are awesome. It now affects 4.6 million Americans, and 400,000 new cases are diagnosed each year. After a diagnosis is made, less than 50% of patients survive more than five years, and less than 25% survive more than 10 years. Class IV heart failure carries about a 50% mortality in one year. Deaths from heart failure rose 120% from 1979 to 1996, and ho...

Abstract Drought tolerance in Miscanthus sinensis is a desirable trait because of its potential use to develop new varieties, namely intra‐specific hybrids, adapted drought‐prone marginal lands. In this study, drought was evaluated on 8 M. hybrids (GRC1–GRC8). Plants were grown the growth chamber (14/10 h, 25/20°C, 70% relative air humidity and 300 μmol m −2 s −1 irradiance). induced by withhol...

Fish larvae experience major cellular and biochemical changes during their early life stages.The aim of the present study was to evaluate alterations in the antioxidant status and values oflipid peroxidation and vitamin C content during the different life developmental stages ofHypophthalmichthys molitrix. Eggs and larvae were sampled at fertilization, organogenesis,eyed egg, hatch, active feed...

S OF PAPERS 217 were fed corn-soy diets containing 0, 0.5, 1.0 or 2.0% SP-1 for 28 days. Chicks were grown in an environmentally controlled room with feed and water provided ad libitum. At day 21, abdominal fat pads were collected from six chicks per treatment for FA analysis. At 7 and 21 days of age, 12 chicks from each treatment groups were intravenously injected with 1ml of 7% sheep red bloo...

The menstrual cycle provokes several physiological changes that could influence autonomic regulatory mechanisms. We studied the carotid-cardiac baroreflex in ten healthy young women on four occasions over the course of their menstrual cycles (days 0-8, 9-14, 15-20 and 21-25). We drew blood during each session for analysis of oestrogen, progesterone and noradrenaline (norepinephrine) levels, and...

background: this investigation describes the cyto-architectural alterations observed in the corpuscles of stannius of stinging catfish heteropneustes fossilis after treatment with a botanical pesticide nerium indicum. methods: heteropneustes fossilis were subjected to 11.27 and 2.81 mg/l of nerium indicum leaf extract over short- and long-term exposure periods, respectively. blood was collected...

Ostrich meat samples were irradiated with 0.0, 1.0 and 3.0 kGy of gamma rays, packaged under vacuum and held refrigerated for 21 days. Lipid oxidation, shear force, colour and sensory quality were determined on day 0, 7, 14 and 21. Irradiated meat showed higher values (P<0.05) for a* (redness) than the non-irradiated samples as from day 21 under refrigeration. Irradiation increased (P<0.05) the...
