  • Objectives : The purpose of this study is to investigate effects on the immune system of Bombyx mori L. and Liriopis seu Ophiopogonis Tuber mixture (BL) in Thymus, Lymph Nodes. Methods : Eight-week-old male Balb/c mice were divided into five groups : Group one included the normal mice (Nor). Positive control group two administrated with red ginseng (RG) 100 mg/kg. Group three administrated with Bombyx mori L. (BX) 300 mg/kg. Group four administrated with Liriopis seu Ophiopogonis Tuber (LP) 300 mg/kg. Group five administrated with the mixture of Bombyx mori L. and Liriopis seu Ophiopogonis Tuber (BL) 300 mg/kg. After 2 weeks administration, mice were sacrified and antigen receptor in Thymus, Lymph Nodes was analyzed by using Fluorescence Activated Cellorter Sorting (FACS). we counted the total of Thymus and Lymph Nodes cells. GOT (glutamlc oxaloacetic transaminase), GPT (glutamlc pyruvic transamlnase) in serum were analyzed after experiment. Results : In Effects of Nor, RG, BX, LP, BL on the ratio of CD4+CD8+, CD4+CD69+ and CD4+CD25+ T cell in Thymus and Lymphnode, BL is higher than other groups except Nor in CD4+, CD4+CD69+, CD4+CD25+ T cell. The number of Thymus and Lymph Nodes increased in BL. In the level of GOT and GPT, BL decreased comparing to others group except Nor. Conclusions : BL may have effect on T cells in Thymus, Lymph Nodes. In addition, Bombyx mori could be immune functional material with others herb materials.

  • The silk fibre Produced by the larvae of the lepidopter of the Bombyx mori species is no doubt one of the most precious raw materials employed in manufacturing textile products. The present report, however, deals with silk not as a traditional textile fibre, but as a starting material fer biomedical applications. In recent years, the unique chemical and mechanical properties of silk have made this protein polymer highly attractive for innovative applications, which mainly focus on the development of devices for biomedical uses.

  • Stimulation of fecundity following female antennal amputation has been reported for the first time in silkworm. Antennal amputation caused significant increase in fecundity in two newly evolved multivoltine silkworm breeds viz., BL 67 and 96A. This study indicated better chances for increasing egg yield and the increase in fecundity may be attributed to the action of some neurohormones. Significance of antennal amputation in silkworm has been discussed.

  • The number of chromosomes of the wild mulberry silkworm, Bombyx mandarina, collected in Suwon area in the middle part of Korean peninsula was investigated. The chromosomes were examined after smearing and squashing the testis of the last instar larvae which were at spining stage and the microscopic observation showed that the number of chromosomes of the wild mulberry silkworm was 27.

  • The nuclear polyhedrosis virus (NPV) resistance of silkworm is controlled by a pair of dominant genes on autosome and micro-effect modificator genes on sex chromosome Z and has the phenomenon of patroclinal inheritance. Based on its hereditary characteristics, methods of preparing near isogenic lines and their $F_2$ populations for screening molecular markers were designed.

  • While studying Bombyx mori "Zipnuae" inoculated with an entomopathogenic fungus, Paecilomyces tenuipes, a mycoparasitic hymenoascomycete with a long neck was isolated from the silkworm rearing room. The fungus was identified as Syspastospora parasitica which has been recognized as a hyperparasite on various moniliaceous hyphomycetes. A descriptive illustration is presented in this study.

  • The wild silkworm, Bombyx mandarina, was believed the only ancestor of B. mori, inhabits the limited area of Eastern Asia including China, Korea and Japan. However, the geographic dimorphism of B. mandarina was reported with chromosome number and arylphorin gene. In connection with those dimorphism, we studied the genetic differences of ITS-2 region in rDNA purposing the differentiation and geographic variation within the species of B. mandarina. (omitted)

  • Experiments were held in Egypt to test a new Package of practices for commercial cocoon production, including adding secondary macro and micronutrients to the mulberry garden, disease free rearing regime, low temperature rearing in young instars and natural mounting fur silkworms. This package for seed silkworm rearing lead to increase in fecundity by 67-121eggs (15.12-26.22%) and yield of standard boxes per 1 parent egg boxes by 57-58 egg boxes(48.33-51.66%) respectively in comparison th the traditional cocoon production technology.

  • A silkworm Bombyx mori genomic DNA library was constructed from polyphagous J111 strain and unpolyphagous $C_3$ strain to develop the genomic study by DNA makers. Genomic DNAs of two strains were digested with restriction enzyme EcoRI and ligated into pUC18. The ligated plasmids were transferred into E. coli host strain DH5$\alpha$. When the genomic DNAs were hybridized with insert DNAs from transformant, could be categorized from hybridization patterns to three groups as high repetitive sequence, moderately repetitive sequence, and low-copy number sequences. A total of 219 clones containing single or low-copy number sequence inserts were examined for any polymorphisms between two strains of J111 and $C_3$. Forty six clones showed RFLPs and 10 of these clones were used as a probe of analysis of $F_2$ population derived from crossing between J111 and $C_3$ strain. The genetic inheritance tested with each clones will be important tools to construct the genetic map of the silkworm, Bombyx mori.
