Breeding for high specific immune reactivity affects sensitivity to the environment

Reactivity to sorbitan sesquioleate affects reactivity to fragrance mix I.

BACKGROUND Fragrance mix I (FM I) and its single constituents contain 5% and 1% sorbitan sesquioleate (SSO), respectively. SSO is a rare sensitizer and a potential irritant. OBJECTIVES To determine whether the outcome of the FM I breakdown test is affected by positive patch test reactivity to SSO. METHODS A retrospective analysis of data from the Information Network of Departments of Dermat...

A Physiological Approach to Breeding for Environment

Huisman, Van Vliet and Sebens (1958) reported a difference between the oxygen dissociation curves of the two sheep haemoglobins and suggested that natural selection would favour haemoglobin A at high altitudes. They also postulated an advantage for Hb B at sea level. The difference in oxygen dissociation curves has been confirmed (Dawson and Evans 1962; Naughton et al. 1963;. Sirs 1966). Dawson...

consequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir

there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...

Cholinergic Receptor Sensitivity Following Pharmacological Modulation of the Immune System

Objective. To study the effect of immunomodulators on learning and memory and on cholinergic receptor sensitivity. Methods. Animals were initially treated for a period of 8 days with cyclosporine/levamisole/saline. They were then subjected to passive avoidance training and 48 hrs later, the retention test for the passive avoidance task was conducted. Twenty-four hours after the retention tests ...
