Acta Anatomica Sinica 1953;0(01):-
Objective\ The adrenal gland is a linkage between nervous system and endocrine system.Its cortex results from mesoderm,and medulla derives from neuroectoderm.Searching its double characteristic of nervous and endocrine tissue is our aim. Methods\ Histochemical and immunohistochemical staining techniques were used,and immunostained sections were observed under a light microscopy. Results\ NPY positive neuron and nerve fiber,CGRP positive nerve fiber existed in adrenal cortex.NADPH d positive neuron and nerve fiber, c fos positive neuron and nerve fiber,CGRP positive nerve fiber,SP positive nerve fiber were detected in adrenal medulla.NADPH d positive cell,NPY positive cell,CGRP positive cell,SP positive cell were found among the adrenal chromaffin cells.The zona glomerulosa,zone fasciculata and zona reticularis were stained strongly by NADPH d in cortex. Conclusion\ The adrenal gland was innervated by NO ergic,NPY ergic,CGRP ergic,SP ergic, c fos ergic nerves.The adrenal parenchyma,especially chromaffin cells can produce NO,NPY,CGRP,SP which regulate adrenal endocrine by itself.The nervous control of adrenal function and neuroendocrine function of adrenal gland is more complex than hitherto believed.\;

Objective To evaluate the effects of propofol,etomidate and midazolam on gap junction function in rats in vitro and in vivo.Methods Experiment Ⅰ NRK52E cells were seeded in 6-well plates with the density of 1.0 × 105/ml and randomly divided into 4 groups (n =6 wells each):control group (group C),propofol group (group P),etomidate group (group E) and midazolam group (group M).In group C,NRK52E cells were cultured in DMEM-F12 culture medium containing 10% fetal bovine serum.In P,E and M groups,propofol,etomidate and midazolam (with the final concentrations of 15,8 and 4μmol/L,respectively) were added to the culture medium,respectively,and the cells were then incubated for 1 h.Parachute dye-coupling assay was used to measure the gap junction function in NRK52E cells.Experiment Ⅱ Twenty-four male Sprague-Dawley rats,aged 2 months,weighing 220-280 g,were randomly divided into 4 groups (n =6 each):propofol group (group P),etomidate group (group E),midazolam group (group M),and control group (group C).In P,E and M groups,propofol 100 mg/kg,etomidate 6 mg/kg and midazolam 5 mg/kg were injected intraperitoneally once a day for 3 consecutive days,respectively.The equal volume of normal saline was given instead in group C.The animals were sacrificed at 30 min after the last administration and the renal cortex was harvested to measure the gap junction function using tissue scrape and load assay.Results Compared with group C,the gap junction function was significantly decreased in P and E groups (P < 0.05),and no significant change was found in the gap junction function in group M (P > 0.05).Conclusion Propofol and etomidate significantly inhibit the gap junction function in NRK52E cells and renal tissues in rats,but midazolam produces no effect.

Objective To evaluate the diagnostic value of conventional ultrasound and ultrasonic elastography (UE) in differentiating benign and malignant hepatic lesions.Methods One hundred and forty-five patients with 159 hepatic tumors were included in the study.Conventional ultrasound scan and UE were performed on each patient.Pathological results were as the golden standard.The diagnostic performance of the 2 methods were evaluated with receiver operating characteristic (ROC) curves and the interobserver agreements were analysed.Results A better interobserver agreement was achieved in UE (κ =0.325 at conventional ultrasound versus κ =0.782 at UE).The area under ROC curve of conventional ultrasound,ultrasonic elastography and the combination of both methods were 0.76,0.77 and 0.87,respectively.After the combination of the 2 methods,the sensitivity and accuracy could be enhanced significantly ( P <0.05).Conclusions Conventional ultrasound combined with UE may be more helpful in differentiating malignant from benign hepatic tumors.

Objective To explore the relationship between dopaminergic axon terminal and GABAergic neurons and explore the neuroanatomic mechanism of their effects in schizophrenia. Methods The co-location and the association of dopaminergic axon terminal and GABAergic neurons in the basolateral nucleus (BL) of rat amygdala were examined by using double labeling immunoelectron microscopic techniques. Dopaminergic axon terminal and GABAergic neurons were labeled with the antidopamine (anti-DA) and the anti-glutamic acid decarboxylase (anti-GAD) antibodies respectively. Results 43% of the DA-input synapses was observed to relate directly or indirectly to GAD-immunoreactive(IR) dendritic structures(DA/GAD), which includes single (38%), convergent (30%), serial (20%), and axoaxonic (12%) contact types.And 57% of the DA-input synapses was found to associate with unlabeled elements (DA/UE), which includes unlabeled perikarya (10%), dendrites (82%) and axons (8%). All of the synapses that show DA-IR terminals profiles were found to be symmetric (inhibitory) synapses.Conclusion These results suggest that the dopaminergic system in the BL of rat amygdala controls the mediations of the GABAergic interneurons via symmetric synapses. In addition, the dopaminergic axon terminal associates with the glutamatergic projection neurons and exerts influence on its activity.
