Divergent axon collaterals from forebrain and brainstem to the dorsal hippocampus in the rat were examined by means of HRP method and fluorescent retrograde double labeling method.HRP solution was injected into the left or right dorsal htppocampus of 3 rats. HRP labeled cells were observed in the bilateral medial parts of medial septal areas, vertical limbs of the diagonal band of Broca, supramammillary nuclei, submammillothalamic nuclei, superior central nucleus and locus ceruleus.PI and Bb solution were injected into the left and right hippocampus of 3 rats separately. Many retrograde double labeled cells were found in the nuclei mentioned above.The results indicate that the retrograde double labeled ceils in these nuclei may divergently projected to both the left and right dorsal hippocampi. They play an important role in harmonizing the activity of bilateral hippocampi.

The length and diameter of trachea,bronchus and segmental bronchi were mea-sured from 70 cases (50 adults and 20 children).The length of the segmental bronchi of left lower lobe is always longer thanthat of left upper lobe.The length of the segmental bronchi of right lung showed a regular decreasefrom lower lobe to upper lobe.Using the multivariate statistical analysis the correlations between internalindices such as the length,diameter etc and external indices such as the height dia-meter of chest etc were also studied.

The diaphyseal nutrient foramina of 123 pairs of radius and 112 pairs of ulna from local Chinese adult skeleton collection have been observed. Their length, diameter and circumference were measured.The nutrient foramina on the shaft of radius, in longitudinal direction, located near the junction of the upper and middle thirds, and those of ulna located a little lower.In horizontal direction, the nutrient foramina chiefly concentrated on the anterior surface. But there were more foramina situated on the interosseous crest or posterior surface on radius than that on ulna.100 cases of nutrient artery to radius and ulna have been dissected on preserved cadavers. The length, diameter and distance from the origin of the artery to the level of elbow joint have been measured. The nutrient arteries to radius and ulna may have. various origins. They mostly arise from anterior interosseous, common interosseous, ulnar, ulnar recurrent and rarely from radial, median or dorsal interosseous arteries.The course and distribution of the nutrient arteries in the bone marrow cavity were examined on X-ray films prepared from injected radio-opaque specimens.

Funds management,which has a direct effect on the development of scientific research projects,is an important part of the scientific research management in hospitals.By investigating the present situation of the scientific research funds management in a local hospital in Shanghai,this paper analyzes the problems commonly found in the scientific research funds management.Based on the findings of the analysis,this paper proposes some corresponding recommendations and countermeasures to improve the management.
