BACKGROUND: Cyclin-dependent kinase-5 (CDK-5) is one of the members in cyclin-dependent protein kinase family. The attention has being drawn by researchers on the relationship between the expression and distribution of CDK-5 mRNA and its protein in the brain during brain development and neural degeneration in thought-cognition.OBJECTIVE: To probe into the influence of CDK-5 on neurogeny and neural degeneration during cerebral development.DESIGN: Single factor analysis of variance.SETTING: Histological and Embryological Department and Neurobiological Department in Third Military Medical University of Chinese PLA.MATERIALS: The experiment was performed in Histological and Embryological Department and Neurobiological Department in Third Military Medical University of Chinese PLA. Twenty-five Wistar rats of 5 phases were employed, named embryonicphase (E8-E21), neonatal phase (P0-P15),childhood (P16-2 months), grown-up phase (＞ 2 months) and senile phase (＞ 8 months), 5 rats in each group.METHODS: In situ hybridization histochemistry (ISH) and immunohistochemistry (IHC) staining was adopted in brain sections from embryonic phase to senile phase.MAIN OUTCOME MEASURFS: Distribution and expression of positive cells of CDK-5 mRNA and protein in various brain areas.RESULTS: Twenty-five rats entered result analysis for all. ① The expression of CDK-5 mRNA presented in entire development from E14 to P350and was in tendency of stability after growth-up. CDK-5 mRNA localized mainly in neurons and positive regions distributed mainly in cerebral cortex, hippocampus, thalamus, hypothalamus, cerebellum and a part of nerve nuclei. ② The expression of CDK-5 was strong after birth and it was weaker in embryonic and senile rats. Positive regions concentrated mainly in peripheral ventricle, hippocampus, cerebellum and a part of nerve nuclei.The expression only presented in hippocampus and Purkinje cellular layer of cerebellum in senile rats.CONCLUSION: CDK-5 in brain runs through entire phases of neural development, it expresses more significantly in neonatal phase and childhood and declines after growth-up, especially in senile phase. The declined expression of CDK-5 in hippocampus of senile rats is closely associated with decline of learning and memory in senility probably.

Objective To observe the change of nitric oxide(NO) content and explore its cell source following brain ischemic injury. Methods We established the model of transient global brain ischemia/reperfusion (IR) in rat. The concentration of NO and its cell source were investigated by detection of NO content, NDP histochemical staining, double label technique of immunofluorescence and stereological analysis after brain ischemia. Results (1)The content of NO increased at 12 h and peaked on days 1～3 after IR. The content of NO decreased gradually on the 5th day after IR. (2)The density of NDP positive cells increased and peaked on the 1st day after IR. The positive cells distributed mainly in the temporal cortex, hippocampus and periventricular zone after IR. The positive cells were found to reduce gradually or disappear on the 14th day after IR. (3)Few NDP positive and GFAP immunofluorescence positive cells were found to coexist at the early period of IR(1～3 d). The percentage of coexisting cells was 10%～15%. Conclusion The content of NO increases at the early period after ischemic brain injury. The main cell type to produce NO is neuron.

In this study gloxylic acid-induced fluorescent histochemical method was usedto reveal the innervation of adrenergic nerves,acetycholinesterase (AChE) methodto show the cholinergic nerves,and the immunohistochemical method to display thevasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) immunoreactivenerves.This observation on the vas deferens showed that the VIP-immunoreactivenerves had the same distribution as the cholinergic nerves,and mainly existed inlamina propria,while NPY-immunoreactive nerves had the same distribution asadrenergic nerves and mainly existed in the muscular layer.One group of animalswas treated by intraperitoneal injections of 6-OHDA on the lst,2nd,6th and 7thday,and killed on the 8th day.Following treatment with 6-OHDA,significantevanescence of most adrenergic nerves was observed.NPY-immunoreactive nervesreduced remarkably and the extent of the decrease was similiar to that of adrenergicnerves,whereas no change was observed on the VIP and cholinergic nerves.Theimmunoelectronic microscopy (PAP pre-embedding method) demonstrated that VIPimmunoreactive complex deposited in the varicosity containing small clear vesicles(diameter of 40-55nm).Some varicosities also contained small number of largegranular vesicles with the diameter of 100-144mm.NPY immunoreactive complexdeposited in the large granular vesicles,and occasionally can be observed in thesmall granular vesicles,40-55nm in diameter.The results from this study suggestthat VIP probably co-exist with ACh and NPY with noradrenalin in rat vasdeferens.

BACKGROUND:The researches about the effect of retinoic acid on the proliferation of adipose-derived stem cells are rare, and the researches on the testosterone are mainly on the inhibition of cellaging. OBJECTIVE: To study the effects of retinoic acid and testosterone or combination on the cellcycle of adipose derived stem cells. METHODS:Adipose derived stem cells were isolated from adult female Sprague Dawley rats with 2 months age and cultured in vitro til passage 3 adipose derived stem cells, and then the 3rd passage adipose-derived stem cells were performed with adipogenic induction, osteogenic induction and surface marker identification. The cells were divided into six groups:(1) Control group;(2) 10-5 mol/L retinoic acid group;(3) Retinoic acid group;(4) 10-5 mol/L retinoic acid+testosterone group;(5) 10-6 mol/L retinoic acid+testosterone group;(6) Testosterone group. The adipose-derived stem cells in the control group were cultured with Dulbecco’s modified Eagle’s medium+10%fetal bovine serum culture medium, and the adipose-derived stem cells in the other five groups were induced with corresponding dose of retinoic acid and testosterone on the basis of control group. After cultured for 36 hours, the flow cytometry was used to detect the changes of cellcycle. RESULTS AND CONCLUSION:Compared with the control group, cellproportions in phase G 1 of 10-5 mol/L retinoic acid group and 10-6 mol/L retinoic acid group were increased significantly, and the cellproportions in phase S were decreased. Compared with control group, the cellproportion in phase G 1 of testosterone group was significantly reduced, and the cellproportion in phase S was increased. Compared with 10-5 mol/L retinoic acid group and 10-6 mol/L retinoic acid group, cellproportions in phase G 1 of 10-5 mol/L retinoic acid+testosterone group and 10-6 mol/L retinoic acid+testosterone group were reduced significantly and the cellproportions in phase S were increased. Retinoic acid can inhibit the cellcycle of adipose-derived stem cells in phase G 1 , and delay the process of the cellcycle from phase G1 to phase S;while testosterone can promote the cellcycle of adipose-derived stem cells from phase G1 to phase S;the combination induction of retinoic acid and testosterone can accelerate the process of the cellcycle of adipose-derived stem cells from phase G 1 to phase S.

Objective To evaluate the therapeutical effect of dopaminergic neurons induced by transplantation on Parkinson's disease (PD) rats. Methods Mesencephalic nerve stem cells (NSCs) were induced by striatal extracts to differentiate into tyroxine hydroxylase (TH) positive dopaminergic neurons. The differentiated cells were transplanted into the striatum of PD rats. The survived cells were detected by TH immunocytochemical staining. The therapeutical effect was observed using apomorphine induced rotation. Results Mesencephalic NSCs could be induced to differentiate into dopaminergic neurons which could survive in the host for long time after cell transplantation, and could improve the apomorphine induced rotation. Conclusion The induced mesencephalic NSCs have the obvious therapeutical effect on PD.

Objective To investigate the clinical features,radiology,diagnosis and treatment of postkidney-transplant pulmonary mucormycosis.Method Three cases of post-kidney-transplant pulmonary mucormycosis were successfully diagnosed by histopathologic examinations.The clinical features of the cases were analyzed.The patients consisted of 2 males and 1 female,aged 39 to 54 yearn All patients were subjected to renal transplantation due to uremia,one was complicated with with diabetes,and pulmonary mucormycosis occurred 6 months,2 years and 6 years after kidney transplant respectively.Fever,cough,bloody sputum and chest pain were the main clinical manifestations.Multiple irregular massive or diffuse infiltrates in the lungs were the early CT findings.In a shoot time,multiple thick-walled cavities occurred in the pulmonary lesions.Pleural effusion was found in one patient.The lung specimens of patients were obtained by CT-guided percutaneous biopsy.Result The first patiem was cured after one year therapy by hraconazole,but recurred after 8 months.The second patient had a marked effect after a 21-day therapy by Itraconazole,but died of disseminated mucor for excessive immunosuppressant against the renal transplantation rejection.The third patient also had a marked effect,and was still in follow up.Condusion The post-kidney-transplant pulmonary mucormycosis is difficult in diagnosis and treatment.CT-guided percutaneous biopsy is one of effective ways for diagnosis.Itraconazole appears to be effective in treatment of pulmonary mucormycosis.Early diagnosis and an appropriate immune ftmction are the keys to improve prognosis and reduce recurrence
