4.AN OBSERVATION ON THE ULTRASTRUCTURE AND MORPHOLOGY OF KERATOHYALIN GRANULES DURING KERATINIZATION OF SHEEP ORAL EPITHELIUM
Acta Anatomica Sinica 1955;0(03):-
Tissue samples from sheep oral epithelium of different age groups were fixed with three different fixatives to observe the ultrastructure of keratohyalin granules. Two conclusions were: 1. There were two types of keratohyalin granules in the sheep oral epithelium. The morphology and ultrastructure of type Ⅰ granules underwent alteration during epithelial development. The shape of granules changed from round to irregular by the combination with tonofilament bundles. Finally, the granules disappeared from several sites of mature oral epithelium. Type Ⅱ granules were round or oval in shape and were surrounded by free ribosomes. They did not have morphologic or ultrastructural changes during epithelial development. They appeared in immature oral epithelium, and constantly presented in mature epithelium. 2. According to the reaction of the two types of granules with the fixatives, it is suggested that the composition of type Ⅰ granules has the property of lipoprotein and the component of type Ⅱ granules possesses the nature of unsaturated lipid in addition to the lipoprotein.

Chinese Journal of Tissue Engineering Research 2001;5(23):144-145
Objective To investigate the different effects of clozapine and risperidone on levels of blood glucose in patients with schizophrenia. Method 200 qualified cases selected from psychiatric department were divided into two groups randomly, of which 100 cases accepted the treatment with clozapine and the other 100 cases with risperidone. Blood glucose tests were used before treatment ,4 weeks after treatment and 8 weeks after treatment Results There was significantly higher blood glucose level in clozapine- treated group than in risperidone- treated group after 4 or 8 weeks treatment. The number of cases who had elevated blood glucose level (>6.1 mmol/L) in clozapine- treated group was significantly more than in risperidone- treated group. Conclusion The glucoregulatory abnormality which leads to glucose elevation in clozapine- treated patients is greater than in risperidone- treated patients. Additional motivation to clinical monitor for antipsychotic treatment- related hyperglycemia is indicated.

Chinese Journal of Geriatrics 2009;28(9):777-779
Objective To explore the current status and influencing factors of fall among the elderly in Niujie area of Beijing so as to provide evidences for prevention. Methods Based on the basic survey of fall in 1703 elderly people, the people were divided into intervention group and control group according to different habitation areas using cluster sampling method. The elderly people in intervention group of 874 were accepted intervention management for one year, including cognitive behavioral intervention, fall-inducing diseases intervention and intervention of elderly static and dynamic behaviors that affected the balance function, so as to help the elderly to master the relevantfactors of fall and preventive measures. Results The annual occurrence rate of fall was 11.7% (200/1703) and the fall injury incidence was 9.0% (152/1703). The prevalence of fall was increased with aging, and it was high in people with balance dysfunction. After one year intervention, the incidence of fall was decreased to 5.2%, while it was 7.6% in control group. Conclusions Cognitive behavior intervention can effectively prevent fall in the elderly, which has an important significance for improving the life quality of the elderly.
