The secretory function of the parotid glands, as represented by the salivary secretion rate, has been examined in 10 patients with parotid hyperplasia U.N.S. Different levels of gustatory stimulation were used. The secretion rate was reduced in 8 out of 10 of the patients at a moderately high level of stimulation but normal at submaximum levels in all the 10 patients. The results suggest that the cause of the parotid hyperplasia may be an elevated sympathetic influence, possibly due to stress.
Performance and cost of the best available analytical methodology for the measurement of aluminum in parenteral products are presented. Typical levels of aluminum in representative solutions are summarized. A methodical approach to the minimization of aluminum contamination in the manufacturing process is considered in light of aqueous aluminum chemical considerations. Results of long-term clinical follow-up studies of infants maintained on currently manufactured TPN solutions indicate no adverse pathology arising from aluminum.
