1.EFFECT OF EXOGENOUS HORMONES ON LYMPHATIC STOMATA IN OVARIAN BURSA AND LYMPHATIC DRAINAGE IN MICE
Acta Anatomica Sinica 1957;0(04):-
Objective To investigate the effect of steroid hormones on lymphatic stomata of ovarian bursa and fluid adsorption. Methods The lymphatic adsorption was traced by trypan blue,and the ultrastructure of the lymphatic stomata and estrogen receptor level of mesothelial cells on ovarian bursa was observed by scanning electron microscopy,transmission electron microscopy and immuno-colloid golden technology. Results The absorption and opening area of lymphatic stomata were enhanced in estrogen group mice,and decreased in androgen group as compared to control group mice.Estrogen receptor was first identified in the nuclei of mesothelial cells on the inner layer of mice ovarian bursa and the level was down-regulated by estrogen and slightly up-regulated by androgen.Conclusion The absorption and the opening area of lymphatic stomata can be regulated by steroid hormones in mice,and the machanism may be related to the expression levels of estrogen receptor in the nuclei of mesothelial cells.

ObjectiveTo investigate advantage and disadvantage of different rehabilitation therapies used for cerebral palsy (CP) children complicated with epilepsy (EP).Methods140 CP children complicated with EP screened from 1402 CP cases, were analyzed for CP and EP types, MRI or CT, brain stem auditory evoked potentials (BAEP). All cases were treated with anti-epilepsy drugs (AEDs). Different rehabilitation therapies, including electrotherapeutic modalities, acupuncture, point injection, cerebroprotein hydrolysate injection, manual therapy, functional training, Chinese herb braising therapy, and cattle encephalon glycoside and ignotin injection were assessed.ResultsIn all 140 cases, a majority of EP types were myoclonic seizure and west syndrome, CP type was spasticity. Abnormality showed in MRI or CT (98%) and BAEP (90%). AEDs were effective for all 140 cases. Electrotherapeutic modalities, acupuncture, point injection, and cerebroprotein hydrolysate injection could make EP severely, but manual therapy, functional training, Chinese herb braising therapy, cattle encephalon glycoside and ignotin injection had no adverse effects on EP cases.ConclusionThe principles of rehabilitation treatment for the CP children complicated with EP are taking AEDs early and in a long term, avoiding electrotherapeutic modalities, acupuncture, point injection, and cerebroprotein hydrolysate injection, using manual therapy, functional training, Chinese herb braising therapy, and cattle encephalon glycoside and ignotin injection.

p70 ribosomal protein S6 kinase (p70S6K), an important member of AGC family, is a kind of multifunctional Ser/Thr kinases, which plays an important role in mTOR signaling cascade. The p70 ribosomal protein S6 kinase is closely associated with diverse cellular processes such as protein synthesis, mRNA processing, glucose homeostasis, cell growth and apoptosis. Recent studies have highlighted the important role of S6K in cancer, which arose interests of scientific researchers for the design and discovery of anti-cancer agents. Herein, the mechanisms of S6K and available inhibitors are reviewed.

AIM To evaluate the anti-angiogenesis action of Bevacizumab on corneal neovascularization(CNV) in rats induced by alkali burns.·METHODS: 20 Health Wistar rats, aging from 6 to 8 weeks and weighting from 170g to 190g from 170g to 190g were prepared for CNV animal models. Both corneas of each animal in experimental were cauterized with alkali, then all rats were randomly divided into four groups (each group have 5 rats and 10 corneas), the both corneas of each rats were received subconjunctival Bevacizumab in different dosage (group 2, 0.5rag; group 3, 1.0mg; group 4, 2.0mg)and the group 1 received carrier solution. The occurrence and development ofCNVwereobservedbyslit-lamp microscope, and length and area of CNV were calculated. All rats were followeded up 16 days after alkali burns. The 40 corneas were taken for histopathological examination. Vascular endothelial growth factor (VEGF) were detected in all rat corneas by immunohistochemistry method. ·RESULTS: In the bevacizumabotreated eyes, the vascular area was lower than in the control eyes. The treated group was statistical differences compared with the control group; when vascular area were compared between the treated groups, no statistical differences were observed. The histopathological findings showed that the inflammation cells and the neovascularity in each treated group were significantly fewer than that in the control group. The expression of VEGF markedly increased in CNV control group compared with bevacizumab-injected group. ·CONCLUSION: Subconjunctival application of a certain concentrations Bevacizumab could inhibit angiogenesis in rats corneas induced by alkali burns.
