Objective: To optimize the two types of colchicine ethosome patches using uniform design and to investigate their in vitro release, transdermal properties, stability, and stimulus. Methods: Two kinds of colchicine ethosomes made of soybean lecithin (SL) and hydrogenated phosphatidy (HP) were prepared using injection method. By the DPS 7.0 sotfware, the uniform design was used to optimize the patch components of colchicines, polyacrylic resin IV, succinic acid, triethyl citrate, and azone in patch pressure-sensitive adhesive, with its initial adhesion and hold tack as indexes. The colchicine ethosomes patches of SL and HP were prepared, respectively. The automated dissolution test analyzer and improved Franz diffusion cell were adopted to compare the in vitro release and transdermal properties of the two types of colchicine ethosomes patches, respectively. Moreover, the preparation stability under different light, humidity, and high temperature conditions was studied, and the skin irritation test for rabbits was carried out. Results: The optimized colchicine ethosome patches by the uniform design adhere with the viscous standards in Chinese Pharmacopeia 2010. The in vitro release of the three types of patches were fitted with the Higuchi equation and their release rates increased in turn, respectively, which were (3.1331 ± 0.3272), (2.8724 ± 0.3481), and (2.3802 ± 0.2134) μg/(cm2·h1/2). Their in vitro transdermal releases were fitted with the zero-class equation and increased in turn, respectively, which were (0.9390 ± 0.0731), (0.8775 ± 0.0908), and (0.6167 ± 0.0816) μg/(cm2·h). During the storage, the HP patches had better stability than the SL patches, especially with the stable color. In the skin irritation test for rabbits, there was no erythema and oedema reactions in 48 h. Conclusion: The HP patches have obviously higer in vitro release rate and transdermal rate, and for its better stability of preparation, the HP patches are superior to the SL ones.

Allelic differences in A and B mating-type loci are a prerequisite for the progression of mating in the genus Pleurotus eryngii; thus, the crossing is hampered by this biological barrier in inbreeding. Molecular markers linked to mating types of P. eryngii KNR2312 were investigated with randomly amplified polymorphic DNA to enhance crossing efficiency. An A4-linked sequence was identified and used to find the adjacent genomic region with the entire motif of the A locus from a contig sequenced by PacBio. The sequence-characterized amplified region marker 7-2299 distinguished A4 mating-type monokaryons from KNR2312 and other strains. A BLAST search of flanked sequences revealed that the A4 locus had a general feature consisting of the putative HD1 and HD2 genes. Both putative HD transcription factors contain a homeodomain sequence and a nuclear localization sequence; however, valid dimerization motifs were found only in the HD1 protein. The ACAAT motif, which was reported to have relevance to sex determination, was found in the intergenic region. The SCAR marker could be applicable in the classification of mating types in the P. eryngii breeding program, and the A4 locus could be the basis for a multi-allele detection marker.

BACKGROUND/AIMS: Focal nodular hyperplasia (FNH) is mandatory to be differentiated from other hepatic tumorous conditions such as hepatocellular carcinoma and adenoma. The purpose of this study was to explore the clinical, radiological and pathological features of FNH cases reported in Korea. METHODS: We have searched the journals from the web site "http://koreamed.org" using keywords "focal nodular hyperplasia" and "liver" - total of 38 cases of FNH, 37 cases from 17 published articles and one case from our experience confirmed histologically, were reviewed and analyzed. RESULTS: Thirty eight cases were diagnosed between gestational age of 36 weeks and 67 years. Seventeen female patients (45%) had no history of taking oral contraceptives. Twenty cases (52.6%) experienced clinical symptoms such as abdominal pain and palpable mass. Computed tomography revealed contrast-enhancement in 34 nodules (85%) and typical central stellate scar in 9 (22.5%) of 40 nodules. Magnetic resonance imaging showed T1 weighted low signal in 18 (60%) and T2 weighted high signal in 22 (73.3%) of 30 nodules. Six (60%) of 10 cases showed hypervascular staining on hepatic angiography. Among 38 cases, 32 (84.2%) cases had single nodule and their mean size was 3.9 cm (0.5-16 cm). Pathologically, fibrous septa, proliferation of bile ductules and arterial wall thickening were seen in most cases. CONCLUSIONS: Of all the FNH cases reported in Korea, there were some differences in clinical aspects of sex ratio, accompanying clinical symptoms, and relationship with oral contraceptives, compared with previous reports. Further prospective studies are needed by means of nation-wide clinical survey and analysis.
