ABSTRACT: Chemical peeling is becoming increasingly popular for skin rejuvenation in dermatological esthetic surgery. Conspicuous facial pores are one of the most frequently encountered skin problems in women of all ages. This study was performed to analyze the effectiveness of reducing conspicuous facial pores using glycolic acid chemical peeling (GACP) based on a novel computer analysis of digital-camera-captured images.
GACP was performed a total of five times at 2-week intervals in 22 healthy women. Computerized image analysis of conspicuous, open, and darkened facial pores was performed using the Robo Skin Analyzer CS 50.
The number of conspicuous facial pores decreased significantly in 19 (86%) of the 22 subjects, with a mean improvement rate of 34.6%. The number of open pores decreased significantly in 16 (72%) of the subjects, with a mean improvement rate of 11.0%. The number of darkened pores decreased significantly in 18 (81%) of the subjects, with a mean improvement rate of 34.3%.
GACP significantly reduces the number of conspicuous facial pores. The Robo Skin Analyzer CS 50 is useful for the quantification and analysis of 'pore enlargement', a subtle finding in dermatological esthetic surgery.

ABSTRACT: We reported a 39-year-old, left-handed man with sudden onset hypogeusia. Taste threshold examined by a filter-paper disc method was elevated remarkably on both sides of the tongue. Additionally, the patient showed mild right central facial nerve palsy and mild weakness in the right upper limb. Brain CT showed left putaminal hemorrhage. Brain MRI demonstrated a hemorrhage in the left putamen and edema affecting the insular cortex. In this case, the gustatory information from both sides of the tongue, regardless of whether the nerves cross in a brainstem, is suggested to project to the left insular cortex before ascending to the higher order taste and language areas.

ABSTRACT: To investigate characteristic of lung adenocarcinoma growth behavior, we have established a cell line (rat lung cancer in Nara (RLCNR)) from a tumor induced by N-nitrosobis(2-hydroxypropyl)amine (BHP) in a rat. This clone shows an epithelial cell morphology and grows as sheets in culture with an approximate doubling time of 19.2 h. Ultrastructurally, the RLCNR contains lamellar bodies in cytoplasm and the microvilli are present at the free cell surfaces. The line features well-developed desmosomes. The modal chromosome number of 42 is the same as for normal rat cells and its frequency was established to be 80.5%. To evaluate tumorigenicity, appropriate numbers of the cells were transplanted into syngeneic rats, but no tumor formation occurred. Genetic analyses revealed the RLCNR to have a GGT to GAT mutation at codon 12 of Ki-ras, but no p53 alteration. p16 gene expression was lost, associated with hypermethylation of CpG sites in the 5' upstream region of the gene. These results indicate that the present newly established cell line originated from an alveolar type II lesion of the lung. It should be useful for further investigation of in vivo growth mechanisms, especially tumor progression, of lung adenocarcinomas, since it has low malignant potential.
