Based on the changes in the spectrum characters of guest molecules producedthrough inclusion complex formation with cyclodextrins, we have carried out two aspects of investigation:First, the mechanisms for the host-guest recognition reactions have been studied, such as the interactions between 3-CD and curcumin, the main constituent of the rhizomes of the plant Curcuma longa, the recognition of p-CD towards rubidate, the effective component of the Chinese traditional medicine madder, and the reactions of p-CD towards the antileprotic drug dapsone and the antiinflammatory drug nabumetone: The formation of supramolecular complex between P-CD and guest molecule has been discussed and verified in virtue of multitudinous means such asultraviolet-visible absorption, fluorescence emission, infrared spectrogram and so on. The influence of addition of linear alcohols on the supramolecular system has been studied and the reason why the noncovalent interactions in the three-component system could result in a decrease in the apparent association constant of the inclusion complex has been revealed.

An assumed Gaussian tail is addedonto the HO distribution. The calculations for〓 of the protron-rich isotones 〓〓 and 〓 and for 〓 the neutron-rich isotopes 〓were finished by theGlauber Model along with the modified density distrution. The calculated resultsshow that d values of these nuclei along with the modified density distribution arelower than the calculated ones along with the only HO density distribution.

The long specific DNA probes were synthesized by polymerase chain reaction in the highly specific gene sequences of above 10 bacteria. The species-specific probes synthesized were inoculated on a nitrocellulose filter and hybridized with template DNA labeled with long-arm photosensitive biotin. The signal of hybridization reaction was observed to detect which bacteria infected. The sensitivity and specificity of the method were studied.

RT-PCR was a sensitive and stable method. It would be useful for large-scale diagnosis.A length cDNA of CEVd had been cloned into plasmid vector. Biotinylated probes were prepared from these plasmid DNAs. CEVd were examined from the positive and netative materials by Dot-blotting hybridization and imprint-hybridization. The result was exposed to x-ray film. Singles were detected for positive materials spots probed with probe, indicating that under the reaction conditions the probe hybridized with the target viroid specifically.

Histologically, the seminiferous tubules contained numerous Sertoli cells and more Sertoli-spermatozoa complexes, accompanied by the depletion of Leydig cells with deeply stained nuclei. Mature spermatozoa were stored up in the epididymis, but only a few in the efferent ducts. In the second place was testicular atrophy(32/120; 26.7%). The seminiferous tubules showed moderate to severe inactivity of spermiogenesis with evidence of only spermatogonia, spermatocytes and Sertoli cells. The Leydig cells were obviously decreased in numbers associated with decrease of lipid droplets in their cytoplasms. Testicular hypoplasia was the third disorders(22/120; 18.3%). Only a few spermatogonia and Sertoli cells appeared without any spermiogenesis. The associated changes was decreased in Leydig cells and fibrous hyperplasia in the interstitium.Epididymal stones were sometimes found(12/120; 10%). Grossly, yellowish-white nodules with various sizes and firm in consistency were observed in the epididymis and the front efferent ducts. Microscopically, the epididymal ducts were dilated with voluminous spermatozoa storage, even showed calcification in severe cases. The deposited calcium salts were stained positively by Von Kossa and Alizarin red methods.Amyloidosis was also detected in 10 roosters(8.3%). Eosinophilic, homogeneous, amyloid-like substances were deposited mainly in the testicular interstitium and the periphery of blood vessels. These substances showed positive reaction by Congo red staining. Five roosters(4.2%)had Marek's lesions in the testis, epididymis and peripheral nerves with infiltration of pleomorphic lymphocytes. Only one case showed epithelial necrosis of seminiferous tubules accompanied by fibrous proliferation in the interstitium.
