Whole rice grain was dissected by hand into fractions of pericarp, ale-urone, scutellum, embryo and endosperm. For the convenience of having enough amount of samples for amino acids assay some of which were recom-bined and finally three parts, pericarp +aleurone layer, scutellum + embryo and endosperm, were obtained. Protein, lysine, methionine, threonine and valine contents were determined for each part. The data obtained indicated that although total weight of the first two parts accounted for only 7.27-8.43% of the whole grain, they contributed 14.5-15.8% protein, 29.0-30.5% lysine, 11.8% melhionine, 16.8% valine and 19.4% threonine, contained in the whole grain. During husking process it indicated that the lesser amounts of pericarp, aleurone, scutellum and embryo were retained and the larger percentage of protein and lysine was lost. This fact was identified either by a specially designed miller in the laboratory or a commonly used sand wheel miller in the factory. The suitable degree of milling for rice was discussed and it was proposed that 92% extration for rice rather rational.

Lysine and methionine contents were determined in proteins of 21 rice samples including 17 varieties grown in 11 provinces. Ranges of lysine and methionine contents on crude protein basis were 3.21-3.76% and 1.63-2.06% respectively. The lysine content was found to be negatively correlated with the protein content of rice, but no correlation was found in case of methionine when they were expressed on the basis of crude protein. The absolute amounts of lysine and methionine were positively correlated with protein contained in the samples. The importance of breeding rice variety with protein of high lysine content was discussed in relation to promoting the protein nutritive status in South China.

A convenient microbiological method with high accuracy for cystine assay was introduced. Common foods including cereals, beans, sweet potato, fishes and other aquatic products as well as meats were selected for cystine and methionine analysis. Based on the data obtained, a brief discussion was made on the way for resolution of sulfur amino acids problem inherently in our traditional soy-cereal based diet.

Activity and localization of y-glutamyl transpeptidase (?-GT) , ?-Naph-thyl acetate esterase (ANAE) , alkaline phospbatase (AKP) and glucose-6-phosphatase (G-6-P) in the epididymis of the rat has been investigated histo-chemically by light microscopy.?-GT activity was mainly localized on the supranuclear region and the ste-reocilia of the epithelial cells. The intensity in the epithelium of the segment Ⅱ is the highest of the rat epididymis. There was a gradual decrease in the intensity of this enzyme from segment Ⅲ through Ⅳ and it was absent from the segment Ⅳ. Activity of ANAE in the segment Ⅳ, Ⅴ and Ⅵ was higher, but that in the segment Ⅰ,Ⅱ and Ⅳ was less. ANAE activity was localized throughout the cytoplasm of the epithelial cells in the segment Ⅰ,Ⅲ, Ⅴ and Ⅵ. Whereas the activity in the segment Ⅱ and Ⅳ was localized on the basal region of the epithelial cells. AKP activity was present in the basement membrane of the epididymal epithelium and the bloodvessel wall of subepithelial connective, tissue of the epididymal duct. G-6-P was distributed homogenously in the cytoplasm of the epithelial cells throughout the epididymal duct.The possible function of these enzymes in the rat epididymis are briefly discussed.

Objective To evaluate the academic quality and characteristics of edition of the Chinese Journal of Geriatrics. Methods Within the database of Chinese Medical Citation Index(CMCI), the citation analysis was used to analyze the number and its distribution of the cited original articles published in the Journal 1999-2004. Results The average freguency for a single article cited by other researchers was 2.82, and there were more articles cited than other journals. The authors of these articles were distributed in the 30 province and municipalities, among which Beijing, Guangdong Province, Shanghai were in the front of Geriatrics research. There were 514 cited journals, and self-citing rate was 6.07%. Conclusions The Chinese Journal of Geriatrics has published high quality articles, and has its own edition characteristics to keep its steady level of research. It is one of the most important information resources for the geriatrics researchers and one of the most important medical journal.

Endothelial progenitor cells (EPCs) exist in bone marrow, umbilical cord blood and peripheral blood of adult mammals, including humans. Furthermore, the discovery of EPCs has led to the notion of adult vasculogenesis, in which bone marrow (BM)-derived EPCs home to and incorporate into sites of new blood vessel formation, where they differentiate into endothelial cells, which is consistent with postnatal vasculogenesis. It has become apparent that circulating BM-derived EPCs are involved in promoting physiologic and pathologic neovascularization, such as wound healing and tumor growth. They are of great clinical importance in pro- or anti-angiogenic therapies. [

Objective To investigate the internal relationship between the exp ression of inducible nitric oxide synthase (iNOS) and the activation of NF－? B p65 in the skin of patients with psoriasis vulgaris(PV) and their roles in the p athogenesis of PV. Methods The expression and distribution of iNOS and NF－? Bp 65 were studied by in situ hybridization and immunohistochemistry in 20 patients with PV and 12 healthy controls. The severity of PV was assessed by Psoriasis a nd Severity Index(PASI) score. Results① The expression of both iNOS mRNA and pr otein was significantly higher in lesional epidermis than those in non lesiona l epidermis and epidermis of the controls (P

ObjectiveTo investigate the clinical effect of three-dimensional conformal radiotherapy simultaneously combined with XELOX program(oxaliplatin +capecitabine) for local recurrence of esophageal carcinoma after radiotherapy.MethodsSixty patients with local recurrence of esophageal carcinoma after radiotherapy were divided by random digits table method into treatment group and control group with 30 cases each.The patients in treatment group were treated with three-dimensional conformal radiotherapy simultaneously combined with XELOX program chemotherapy.While control group received three-dimensional conformal radiotherapy.The efficacy between two groups were compared.ResultsThe complete remission rate and efficiency rate in treatment group were significantly higher than those in control group [ 53.3％ (16/30) vs.23.3％ ( 7/30 ),86.7％ ( 26/30 ) vs.63.3％ (19/30) ] ( P ＜ 0.05 ).The 1,2,3-year survival rate and median survival time in treatment group were 65.5％,44.8％,34.5％ and 24.8 months,which were significantly higher than those in control group (48.3％,41.4％,6.9％ and 12.1 months)(P ＜0.01 ).The incidences of radioactive esophagitis,radioactive pneumonia and thrombocytopenia in treatment group were higher than those in control group,but there were no statistical differences between two groups (P ＞0.05).The incidences of nausea,vomiting,leukocyte decrease and anemia in treatment group were significantly higher than those in control group [36.7％(11/30) vs.13.3％(4/30),40.0％(12/30) vs.16.7％(5/30),43.3％( 13/30 ) vs.13.3％(4/30),P ＜ 0.05 ].ConclusionsThree-dimensional conformal radiotherapy simultaneously combined with XELOX program can improve short-term efficacy and long-term survival rate of local recurrence of esophageal carcinoma after radiotherapy.
