The viscosity stability of xanthan solutions is crucial to petroleum recovery processes. The effects of oxygen concentration, pH, and temperature on viscosity during aging up to 6 months were studied. T h e structure modifications of the xanthan (substituent contents, weight-average molecular weight
Elevated activities of superoxide dismutase (SOD) were detected in histidine-requiring strains of Salmonella typhimurium after the bacteria were-preincubated for 1 h at 37OC with S-9 mix and paraquat (methylviologen, PQ") at 1 0 -4 M . A fivefold increase in SOD level was found for strains TA 9 8 an
## Abstract The roles of age and prolactin (PRL) in regulating glucocorticoid secretion in diestrous rats were investigated. Adrenal zona fasciculataβreticularis (ZFR) cells from young, adult, middle (mid)βaged, and old female rats were isolated. Estrous cycle stage was determined by light microsco
