THE PECTORALIS MINOR MUSCLE WITH ANASTOMOSIS OF BLOOD VESSLES AND NERVES FOR THE TREATMENT OF LATE FACIAL PARALYSIS

The treatment of late facial paralysis is numerous,the result is still not satisfactory.Recently,we heve used the pectoralis minor muscle with anastomosis of blood vessles and nerves for the treatment of late facial     

A DISCUSSION ON THE CONVENTIONAL BREEDING OF RICE FOR HIGH EFFICIENCY IN SUNLIGHT UTILIZATION THROUGH HYBRIDIZATION BETWEEN INDICA AND JAPONICA

Early in the 1960's C.M.Donald said:“Plant breeding approaches asbeing largely empirical,”In I976 R.Riley in his address to the Interna-tional Rice Research Conference on recent advance in plant breeding meth-od said:“Plant breeding is a technology,not a science;it produces notknowledge,which is the purpose of science,but material products,that     

DESIGN AND REALIZATION OF REAL TIME KINEMATIC GPS OVER INTERNET FOR “SMART BRIDGE”

The concept and the design of an open Internet based real time kinematic (RTK) global positioning systern (GPS) for a prototype structural monitoring system are introduced. The proposed system consists of four basic segments, i.e. , reference station, monitoring, control and user segments. To validate the feasibility of this prototype system, a platform is used to simulate the bridge movement. Experimental results show that 3 Dpositioning precision of millimetre level at a sampling rate is up to 10 Hz and a negligible transmission delay of RTK corrections is achievable。

PREVALENCE OF THE A AND B TYPES OF EPSTEIN—BARR VIRUS DNA IN NA-SOPHARYNGEAL CARCINOMA BIOPSIES FROM SOUTHERN CHINA

Epstein—Barr virus(EBV)exists in the human population in two genetic forms,usually referred to as type A and type B.Although many earlier studies had indicated that the A type was generally predominant,     

A PARTIAL LIST OF THE INSECT PESTS OF THE GENERA ULMUS COLLECTED IN BEIJING, CHINA

<正> There are more than 200 insect pest spcies of Genera Ulmus have been recorded in China. The following is a list of insect species collected on elm tree in some parts of Beijing region in 1980-1981.     

CYTOMIXIS AND CELL FUSION OF POLLEN CELLS IN F_1 HYBRID OF WHEAT CROSSED WITH RYE, WITH REFERENCE TO THE FORMATION OF ANEUPLOIDS

<正> Cytomixis refers to the migration of chromatin from one cell to an adjacent one. The cytological investigation demonstrated that cytomixis and direct fusion of two cells occurred in early stage of pollen development, and resulted from genetic controlled behaviour in hybrid plants of wheat (Triticum aestivum L. cv. Xiaoyuer mai) crossed with rye (Secale cereale L. cv. Winter rye). The frequency of occurrences of cytomixis and cell fusion was about 10％. Spontaneous seed settings in the hybrid plants were obtained.     

EFFECT OF HUMAN LAK CELLS ON THE IN VIVO GROWTH OF A HUMAN TUMOR CELL LINE ESTABLISHED FROM A UPPER PHARYNGEAL CANCER AS TESTED IN NUDE MICE

The in vivo effect of LAK cells on the growth of a human tumor cell line,CNE—2Z,established from a upper pharyngeal cancer was tested in athymic nude mice and some promising results were obtained.The
