RESUMEN
Hypereosinophilic syndrome is a rare disorder involving the eosin concentration being elevated to more than 1500/µL in the peripheral blood for 6 months, and it causes various complications in the heart, skin, and nervous and respiratory systems. The simultaneous occurrence of neurological complications of hypereosinophilic syndrome is rare. Here we report a patient with hypereosinophilic syndrome who suffered from acute cerebral infarction and peripheral neuropathy during the same period.

Placenta is a special organ that contains many nutrients such as growth factors, minerals, and bioactive peptides. Dipeptides of glycine and leucine are major components of porcine placenta extracts (PPE) that has been used as an alternative of human placenta extracts. In this study, we investigated whether major peptides of PPE, Glycyl-L-Leucine (Gly-Leu), L-Leucyl-Glycine (Leu-Gly), and L-Leucyl-L-Leucine (Leu-Leu), affect skin hydration and elasticity in vitro and in vivo. We found that Gly-Leu and Leu-Gly dipeptides induced the expression of transglutaminase 1 in normal human epidermal keratinocytes (NHEKs) whereas Leu-Leu dipeptides did not. Treatment with Gly-Leu or Leu-Gly significantly increased hyaluronan (HA) synthesis in NHEKs and the upregulation of hyaluronan synthase 2 (HAS2) mRNA level was confirmed. In addition, elastase activity was inhibited in NHEKs treated with Gly-Leu or Leu-Gly dipeptides. Oral administration of Gly-Leu or Leu-Gly dipeptides increased skin hydration and elasticity in UVB-irradiated hairless mice. The significant upregulation of HA in UVB-irradiated hairless mice was observed in response to oral administration of Gly-Leu or Leu-Gly. These results suggest that the major dipeptides of porcine placenta, Gly-Leu and Leu-Gly, are potentially active ingredients for skin moisturization formulations.

Chronic eosinophilic pneumonia is a rare diasease characterized by chronic infiltration of the lung with ~eosinophils, usually associated with peripheral eosinophilia. In 65% of cases, the chest rad Ogroaph shows typiical nonsegmental air-space consolidation confined to the outer third of the lung and in 25)/0 of case "photographic negative of pulmonary edema". Typical lung manifestations with 'peripheral eosinophiliSa' tahrcharacteristic of chronic eosinophilic pneumonia. In the remaining cases, radiographic findings are nonspecific and require lung biopsy for confirmation. We repot a case of chronic eosinophilic pneumonia in which chest radiograph and CT scans revealed bilateral patchy or diffuse opacity with nodules scattered throughout the lungs.
