Abstract
1. Chronic ingestion of caffeine by male NIH strain mice alters the density of a variety of central receptors. 2. The density of cortical A1 adenosine receptors is increased by 20%, while the density of striatal A2A adenosine receptors is unaltered. 3. The densities of cortical beta 1 and cerebellar beta 2 adrenergic receptors are reduced by ca. 25%, while the densities of cortical alpha 1 and alpha 2 adrenergic receptors are not significantly altered. Densities of striatal D1 and D2 dopaminergic receptors are unaltered. The densities of cortical 5 HT1 and 5 HT2 serotonergic receptors are increased by 26-30%. Densities of cortical muscarinic and nicotinic receptors are increased by 40-50%. The density of cortical benzodiazepine-binding sites associated with GABAA receptors is increased by 65%, and the affinity appears slightly decreased. The density of cortical MK-801 sites associated with NMDA-glutaminergic receptors appear unaltered. 4. The density of cortical nitrendipine-binding sites associated with calcium channels is increased by 18%. 5. The results indicate that chronic ingestion of caffeine equivalent to about 100 mg/kg/day in mice causes a wide range of biochemical alterations in the central nervous system.

Abstract
The influence of vibration on dynamic measurements of microdiameters using a laser diffraction-CCD detection system is studied. The theoretical analysis indicates that the influence of vibration on the diffraction pattern of a measured object introduces significant errors into its diameter measurement, and the improvement can be approached by using a TEM(00) Gaussian incident beam instead of the usual uniform beam. The experimental results of these cases are also presented and in good accordance with the theoretical analysis.

Abstract
Monoclonal antibody PAb3 to c-erbB-2/neu protein was utilized in the immunoperoxidase staining of 86 human specimens from oral mucosa. These tissue specimens represented a spectrum from 7 normal to 9 simple hyperplasia, 15 mild dysplasia, 14 moderate dysplasia, 20 severe dysplasia and 21 squamous cell carcinoma. Our study indicated that as the cells acquire a more malignant phenotype, there was a progressive increase in neu expression. It also suggested that neu may be involved in the development of oral cancers and that its evaluation in the early stages may assist in the diagnosis and management of oral cancers.

Abstract
"No man's land" of the flexor tendon system is divided into 4 subdivisions based on our anatomical study. Clinically, a total of 72 flexor tendon injuries in "no man's land" were repaired during the primary and delayed primary stages. Different treatments of flexor tendons, sheath, vincula and postoperative exercises were used according to the degree of injury and anatomical and functional characteristics of each subdivision. The multiple intratendinous suture method, autogenous sheath graft and vincular repair were designed and attempted preliminarily in clinical practice. In 80.4% of the cases, excellent or good results were achieved. Comparison of treatment results in each sub-zone reveals that the IIc sub-zone is the most difficult area for satisfactory functional recovery in "no man's land". The significance of the subdivision of Bunnell's "no man's land" is discussed, and the preoperative assessment method of noting the extent of injury and selection of the treatment method for each sub-zone are presented in this paper. We believe that primary or delayed primary repair can restore good function to the repaired tendons. The effective way of enhancing treatment results of the tendon injury is to apply comprehensive treatment according to the extent of injury to the intrinsic healing capacity of the flexor digitorum profundus tendon.

Abstract
The c-erbB-2/neu gene encodes a transmembrane protein of 185 kDa (p185) with tyrosine kinase activity and extensive sequence homology to epidermal growth factor receptor. Amplification and overexpression of the c-erbB-2/neu gene has been shown in certain human tumors and is postulated to be important in human carcinogenesis. High levels of expression of the c-erbB-2/neu gene have been reported in non-small-cell lung cancer (NSCLC) cell lines and primary tumors from the United States. Since geographical and cultural factors may contribute to the development of certain types of cancer, we examined p185 examined p185 expression in 120 tumors from Chinese patients with lung cancers of different cell types and used immunohistochemical staining to determine the extent and general significance of p185 expression in human primary lung cancer. Our results demonstrate that 58.8% of the NSCLCs expressed p185 and that expression of p185 was observed only in NSCLC and not in small-cell lung cancers. Thirty-three of 41 adenocarcinomas and 24 of 55 squamous cell carcinomas among the NSCLCs examined were found to express p185 at levels different from those of normal lung. For the squamous cell carcinomas, p185 expression was correlated with lymph node metastasis (P less than 0.01), but for the adenocarcinomas, it was not (P greater than 0.05). In addition, expression of p185 in NSCLC was significantly more frequent in patients in advanced clinical stages. Our findings indicate that p185 expression is a frequent event and a general phenomenon in NSCLC and is correlated with poor clinical prognostic indicators, suggesting that expression of p185 may be of potential prognostic importance in NSCLC.
