The clinical manifestation and EEG of 20 cas-es of the patients with damage to nervous systemby pulmonary trematoaiasis are analyzed in the ar-ticle. Those cases made up 30. 3% of the totalnumber of the patients suffered form pulmonarytrematodiasis treated during the same period of thetime. Their clinical signs and symptoms, apartfrom those of Lungs, of skin, and of muscule,were headache, hemiplegia, aphasia, epilepsy,haemorrage in the subarchnoid space and impair-ment of multiple cranial nerves. besides, therewas also a case with damage to the spinal cord. Cases with abnormal EEG constituted 95. 4%of the patients with brain damage. The degree ofthe EEG abnomality varied from case to case ac-cording to the severity and extent of the lesions inpatient brains. Generally speaking, the abnormali-ty of EEG in the cases with cerebral impairmentwas more severe than that in the cases with dam-age only of meningeal. In the cases with circum-scribed granuloma formation the abnormal EEG al-so showed localization. Just for those reasons, authors believe that acontineous check up of EEG is more helpful in pre-dicting the involvement of lesion in the brain, theseverity of the damage and even the outcome of thedisease.

BACKGROUND: Research about magnetic drug microsphere has developed rapidly at home or abroad; additionally, previous studies have been focused on glucan, chitosan, and polyester as coating materials; however, gel material has been less reported,in particular gel-coating berberine microsphere has been not reported yet.OBJECTIVE: To prepare berberine magnetic gelatin drug microsphere, and to evaluate drug releasing, loading, and cross-linking using dynamic dialysis and light electron microscope.DESIGN, TIME AND SETTING: Preparation and property of microsphere were performed in Guizhou Yikang Pharmacy Co., Ltd.And Guizhou University from February 2004 to May 2006.MATERIALS: Gel, berberine, glutaraldehyde, liquid paraffin, and Fe_3O_4 were used in this study.METHODS: Magnetic microspheres of berberine drug with gelatin and Fe_3O_4 were prepared by a reverse phase suspension cold-condensation method according to biocompatibility of gel, solidification of glutaraldehyde, and disperse medium of liquid paraffin.MAIN OUTCOME MEASURES: Structure, morphology, drug-loading rate, entrapment efficiency, and in vitro releasing of drug microsphere.RESULTS: The diameter of the microsphere was under 20 urn. Scanning electron microscope demonstrated that Fe_3O_4 and berberine were compounded by gel into a round shape, and the mixture was expressed on micrometer. Ultraviolet absorption and infrared analysis suggested that berberine magnetic gelatin drug microsphere still had structure and property of raw drug. The drug-loading rate of berberine microsphere was 7.2%, the content of Fe_3O_4 was 20.8%, and the entrapment efficiency was 62.6%.the sustained-releasing ability of microsphere was well, and the releasing content counted for 83.5% of total drug within 7 hours.CONCLUSION: The berberine magnetic gelatin drug microsphere which was prepared by reverse phase suspension cold-condensation method characterizes by sample preparation, small diameter, regular morphology, and great sustained-releasing ability.
