Hair growth promoting potential of phospholipids purified from porcine lung tissues.

BP201, porcine lung tissue-derived phospholipids, consists of phosphatidylcholine as a major phospholipid species. BP201 promoted hair growth after application onto the shaved backs of BALB/c and C3H mice. Its effect was enhanced when applied together with minoxidil (MNX) in C3H mice.

Anti-inflammatory, antinociceptive and anti-angiogenic activities of a phospholipid mixture purified from porcine lung tissues.

This work aimed to assess anti-inflammatory and related properties of a phospholipid mixture purified from porcine lung tissues, named KT&G101, which is being developed as a novel topical remedy for atopic dermatitis. KT&G101 consists of pure phospholipids, mainly phosphatidylcholine (PC) and other phospholipids such as phosphatidylinositol (PI) and phosphatidylserine (PS). Its predominant PC species is 1,2-dipalmitoylphosphatidylcholine (DPPC).

Topical application of a phospholipid mixture purified from pig lungs ameliorates 2,4-dinitrofluorobenzene-induced allergic contact dermatitis in BALB/c mice.

This work was designed to assess the pharmacological effectiveness as a novel anti-atopic dermatitis remedy of a phopholipid mixture purified from pig lung tissues, named KT&G101, using the BALB/c mouse model of allergic contact dermatitis. Allergic contact dermatitis was induced by applying 2,4-dinitrofluorobenzene (DNFB) epicutaneously onto the dorsal skins of mice, and KT&G101 was topically applied onto the skin areas with the lesions. The topical application of KT&G101 (0.

Characterization and regulation of the gene encoding monothiol glutaredoxin 3 in the fission yeast Schizosaccharomyces pombe.

Glutaredoxins (Grxs) are thioloxidoreductases which are required for maintaining thiol/disulfide equilibrium in living cells. The Grx3 gene, which encodes one of the three monothiol Grxs in the fission yeast Schizosaccharomyces pombe, was characterized, and its transcriptional regulation studied. Genomic DNA encoding Grx3 was isolated by PCR, and a plasmid pTT3 carrying this DNA was produced.

Characterization of a second gene encoding gamma-glutamyl transpeptidase from Schizosaccharomyces pombe.

The first gene encoding gamma-glutamyl transpeptidase (GGTI) of the fission yeast has previously been characterized, and its expression was found to be regulated by various oxidative stress-inducing agents. In this work, a second gene, encoding GGTII, was cloned and characterized from the fission yeast Schizosaccharomyces pombe. The structural gene encoding GGTII was amplified from the genomic DNA of the fission yeast and ligated into the shuttle vector pRS316 to generate the recombinant plasmid pPHJ02.

Age-related changes in the activity of antioxidant and redox enzymes in rats.

Cellular defense system, including glutathione, glutathione-related enzymes, and antioxidant and redox enzymes, may play crucial roles in the aging of aerobic organisms. To understand the physiological roles of these factors in the aging process, their levels were compared in the livers and brains of 5-week- and 9-month-old rats. GST activity was higher in livers and brains of 9-month-old rats than in those of 5-week-old rats, and brain catalase activity was about 2-fold higher.
