Effects on colour discrimination during long term exposure to high altitudes on Mt Everest.

Appetite at "high altitude" [Operation Everest III (Comex-'97)]: a simulated ascent of Mount Everest.

We hypothesized that progressive loss of body mass during high-altitude sojourns is largely caused by decreased food intake, possibly due to hypobaric hypoxia. Therefore we assessed the effect of long-term hypobaric hypoxia per se on appetite in eight men who were exposed to a 31-day simulated stay at several altitudes up to the peak of Mt. Everest (8,848 m). Palatable food was provided ad libi...

Long-term Developmental Effects of Lactational Exposure to Lead Acetate on Ovary in Offspring Wistar Rats

Special nerve functions and colour discrimination in workers with long term low level exposure to carbon disulphide.

Certain functions of the peripheral and autonomic nervous systems, and colour discrimination were examined in 45 workers (mean age 49; mean exposure to carbon disulphide (CS2) 20 years) and 37 controls (mean age 48). Conduction velocity and refractory period of the peroneal and sural nerves were determined. The conduction velocity of the slower fibres of the peroneal nerve was measured by means...

Long-term effects of Sulfur Mustard gas exposure on the skin of Iranian combaters

Background: During imposed war (1980-1988) Iraq frequently used chemical warfare particularly mustard gas. Skin is frequently involved in victims. Objective: Our main objective was to evaluate chronic skin manifestations due to exposure to mustard gas 10-19 years after exposure in a case-control study. Patients and Methods: 101 chemically wounded combators and 121 non-chemically wounded c...

The Effect of Long-term Exposure to Aspartame on Histomorphometric and Histochemical Adrenal Gland in Adult NMRI Mice

Abstract Background & aim: Aspartame is an artificial sweetener that has been used extensively in over 200 million people in more than 90 countries in various food products and pharmaceuticals. There are many controversial reports about the toxicity of aspartame on various tissues of the body. Therefore, the aim of the present study was to determine the effect of long-term aspartame on histomor...
