Mycoplasma pneumoniae (M. pneumoniae) infection causes a wide variety of clinical manifestations in children and young adults, the main one being pneumonia. M. pneumoniae is transmitted from person to person by infected respiratory droplets. Symptoms caused by M. pneumoniae infection can be divided into those involving the respiratory tract, and those caused by extrapulmonary disease. M. pneumoniae infections may cause central nervous system (CNS) complications-with encephalitis being the most frequent-and stroke being a rare complication. The pathogenesis of the CNS disease is unclear; possibilities include direct infection and an immune-mediated reaction. We present two cases of CNS complications subsequent to infection with M. pneumoniae; both cases had convincing evidence of preceding M. pneumoniae respiratory disease with no evidence of viable M. pneumoniae in the cerebrospinal fluid. We report cases of encephalitis and stroke following a recent M. pneumoniae infection.

The optimum conditions for the production of tryptophan using a recombinant Klebsiella pnuemoniae phe A tyr A trp R/pSC 101-$trp^{+}$ and its plasmid stability during tryptophan production were studied. The optimum temperature was $37^{\circ}C$ and the specific growth rate was 1.05$h^{-1}$ at $37^{\circ}C$. Tryptophan production was increased by glucose fed-batch culture, and tryptophan was accumulated to 0.175 g/l after 36 hrs. This amount was about 1.2 and 1.6 times greater than that obtained from batch culture and flask culture, respectively. The stability of the strain in fed-batch cu1ture was greatly different from that in repeated flask culture. After 6 generation, 95% of total cells was stable in repeated flash culture, but in fed-batch culture only 50% was stable.

This is clinical report of one patient with pneumonia in stroke who improved with the administration of an herb drug. During treatment for stroke, he broke out with pneumonia, a complication of stroke, which was confirmed by chest radiography. He was administrated Hwangkibyulgap-tang with antibiotics because of old age middle stage pneumonia. After administration, the symptoms improved and chest x-ray film showed no pneumonic finding. This result suggests that oriental medicine is an effective treatment for pneumonia but more clinical case reports are needed.
