[A case of premenopausal metastatic breast cancer treated with goserelin plus aromatase inhibitor as second-line endocrine therapy].

A 44-year-old female with premenopausal advanced breast cancer had been treated with a combination of LH-RH analogue and tamoxifen as primary endocrine therapy following adjuvant chemotherapy. Forty-seven months after operation, because metastases of contralateral axillary lymph nodes were detected by computer tomography, she was treated with a combination of LH-RH analogue and aromatase inhibitor as second-line endocrine therapy. During the 16-month administration of LH-RH analogue and aromatase inhibitor, she was been well without new metastatic lesions and maintained a high quality of life.

Mapping of isolate-specific QTLs for clubroot resistance in Chinese cabbage (Brassica rapa L. ssp. pekinensis).

A number of clubroot resistant (CR) Chinese cabbage cultivars have been developed in Japan using resistant genes from CR European fodder turnips (B. rapa ssp. rapifera). Clubroot resistance in European fodder turnips are known to be controlled by the combined action of several dominant resistance genes. We have developed three Chinese cabbage clubroot-resistant doubled haploid (DH) lines--T136-8, K10, and C9--which express resistance in different manners against two isolates of Plasmodiophora brassicae, M85 and K04. Depending on the isolates, we identified two CR loci, CRk and CRc. CRk was identified by quantitative trait loci (QTL) analysis of an F(2) population derived from a cross between K10 and Q5. This locus showed resistance to both isolates and is located close to Crr3 in linkage group R3. The other locus, CRc was identified by QTL analysis of an F(2) population derived from a cross between C9 and susceptible DH line, 6R. This locus was mapped to linkage group R2 and is independent from any published CR loci. We developed sequence-tagged site markers linked to this locus.
