The influence of ascorbic acid (CAS 50-81-7), acetylsalicylic acid (CAS 50-78-2) and ibuprofen (CAS 15687-27-1) on macrophages of C57BL/6 mice was investigated in vitro. It has been shown that ascorbic acid or acetylsalicylic acid alone did not stimulate or inhibit the production of interleukin-6, whereas a combination of both substances caused a significant stimulation. The viral replication in L929 fibroblasts was not affected by ascorbate and/or acetylsalicylic acid. In addition, the tumor-necrosis factor (TNF) synthesis of peritoneal macrophages was neither stimulated nor inhibited by both substances, alone or in combination. The oxygen radical production, however, was definitely inhibited by ascorbic acid, the effect of acetylsalicylic acid was far less marked, but at the high concentrations the inhibition was clearly discernible. Ibuprofen, a propionic acid derivate, was able to reduce the replication of vesicular stomatitis virus in L929 fibroblast cells. At the highest concentration of ibuprofen, 100 micrograms/ml, 34% of the fibroblast were able to survive. This protective effect declined as the ibuprofen concentration decreased. Ibuprofen could not stimulate peritoneal macrophages to secrete TNF, whereas the oxygen radical production was significantly reduced. In addition, ibuprofen activated mouse macrophages to produce interleukin-6 in a dose dependent way. The results of the in vitro experiments presented clearly show that ascorbic acid, acetylsalicylic acid in ibuprofen influenced the unspecific immune system.

Scurvy, a disease caused by a deficiency of ascorbic acid (vitamin C), is not very common disease especially in pediatric age. In the late nineteenth century, instead, we assisted to increase incidence of this problem for the use of heated milk and convenience foods. We report two cases of scurvy: a child of 3 years old came to our observation for an important gums' stomatitis, fever, widespread petechiae and ecchymosis on the skin of the lower limbs; in the second moment he had pain in upper and lower limbs with difficulty in walking; a second child of 4 years came to our observation for pain lower limbs and maintained the posture of the legs down, inability to walking, with reduced muscle tone and trophism in all limbs; at the instrumental examination he had an alveolar hemorrhage. The two boys had a history of a diet completely lacking in fruits and vegetables; they were drinking almost only milk. They carried various laboratory and instrumental tests, in particular X-ray of lower limbs that showed "a thick sclerotic metaphyseal line with beak-like excrescences of tibiae and femur". The characteristic radiological appearance, the particular clinical aspects, the dietary history and the dosage of vitamin C, have led us to the diagnosis of scurvy. They started therapy with vitamin C and they had a progressive improvement in general condition.
