[A new algorithm for generating Raman spectra using polychromatic light sources].

In the present paper, the possibility of generation of Raman spectra using polychromatic light instead of laser is discussed based on the theory of Raman scattering. When a polychromatic light impinges on a sample, the resultant scattering includes Rayleigh scattering and Raman scattering brought about by the excitation light at each corresponding frequency. Mathematical analysis demonstrates that the scattering spectra after being corrected by the frequency of scattered light are the convolution of Raman-Rayleigh jointed spectrum and the power spectrum of the excitation light. Therefore, Raman spectrum can be obtained with an algorithm of Fourier transformation using polychromatic light as an excitation source.

The cranial cervical ganglion and its branches in the yak (Bos grunniens).

The heads and necks of 10 yaks were dissected to study the shape, location, arrangement, and branches of the cranial cervical ganglion. The ganglion was a greyish fusiform structure, mean length 19.72 mm, width 7.65 mm and depth 4.55 mm, located on the rostrolateral surface of the m. longus capitis. Approximately 25% of the ganglion was covered by the tympanic bulla, the rest by the m. stylohyoideus. The branches of the cranial cervical ganglion included the internal and external carotid nerves, sympathetic trunk and the branches connecting with the glossopharyngeal, vagus and hypoglossal nerves. In one animal the right cranial cervical ganglia was a greyish pyramidal structure 10 mm long, 8 mm wide and 5 mm thick but the left ganglion was similar to those found in the other specimens examined.

The arterial supply to the eye of the bactrian camel (Camelus bactrianus).

The arterial supply to the eye of the bactrian camel (Camelus bactrianus) was studied by gross dissection. The supply came from the external ophthalmic, external ethmoidal and malar and maxillary tubercular arteries, ophthalmic rete mirabile, and the rostral epidural rete mirabile. The external ophthalmic artery gave rise to branches to supply the dorsal oblique muscle, lacrimal gland, superior and inferior eyelids, and the lateral angle of the eye, and to take part in the formation of the rostral epidural rete and the ophthalmic rete mirabile. The external ethmoidal artery detached off some branches to supply the ventral and medial dorsal rectus oblique muscles, the conjunctiva of the superior eyelid and the fat body of the orbit. The branches of the malar artery supplied the inferior, superior and third eyelids, ventral oblique muscle, and the medial angle of the eye. The ophthalmic rete mirabile gave off many branches to supply the rectus muscles of the eye, dorsal oblique and retractor oculi muscles, levator muscle of the superior eyelid, and the choroid.

[RAPD analysis for the genetic diversity of Brassica rapa in Tibet].

Tibet, a most beautiful place, locating in southwestern China. She has been called as the third pole of the earth. Unique geological history, complex land surface and climatic zones, various soil types, all different wild vegetations etc., all of these make Tibet a very typical area of vertical agricultural ecosystem. The ecosystem in Tibet may be the most complex in the world, which varies from place to place. Genetic differentiation of 107 accessions of Brassica rapa from Tibet plateau was studied by DNA PAPD analysis using 2210 bp random primers, the genetical distribution in 107 accession of Brassica rapa from Tibet plateau was found. The results are as follows: (1) Total 236 bands were produced from 107 Tibet oilseed accession of B. rapa germaplasm resource in Tibet, of 210 bands amplified from B. rapa germaplasm resource showed polymorphism, with the ratio 88.98%. The result showed that oilseed accession of B. rapa in Tibet has richer genetic diversity; (2) Dendrogram constructed from DNA RAPDs showed that 107 accessions of B. rapa from Tibet plateau were divided into 11 cluster by calculating genetic distance, the cluster analysis showed that the genetic variation among oilseed accessions of B. rapa was closely related with their eco-geographic distribution; extensive variation existed among the accessions from Tibet Province. Based on the analysis of unique geological history, complex land surface and climatic zones, various soil types, complex growing environments, long agricultural history, different cropping systems, and natural and artificial selection as well as plant geography, plant evolution theory, it concludes that Tibet is one of the oil seed gene centers in the word.

Effects of the N-salicylaladehyde Aminoglucose Schiff Base Complexes no O(2)(-). and DNA.

The effects of SG schiff base complexes with Cu(II), Zn(II), Co(III) on O(2)(-). and DNA were studied. The results showed that both CuSG and ZnSG could an inhibit the synthesis of O(2)(-). markedly. The inhibiting effect of CuSG was larger than that of ZnSG. Complexes CuSG and CoSG could also combine with the salmon sperm DNA. The intrinsic association constant (K(0)) for CuSG and CoSG were estimated to be 2.86x10(4) M(-1 and 1.29x105) M-1 respectively. The numbers of binding sites per 100 nucleotide (n) were 2.5 and 7.5 respectively.
