SOME ANATOMICAL DATA RELATED TO THE TRANSNASO- SPHENOIDAL RESECTION OF PITUITARY FOSSA TUMORS

Since the beginning of this century, trans- naso-sphenoidal resection of the pituitary fossa tumors has been widely used clinically. It has more merits than other operative approaches used before. In China it has been adopted by both ENT doctors and neurosurgeons since 1959.1 In order to afford some relevant anatomical data, we measured 137 adult sagittal plane skulls with distinct landmarks.     

Distribution of rat facial motoneurons and its reorganization following nerve reinnervation]

OBJECTIVE: To examine the distribution of rat facial motoneurons contributing different branches under normal situation and when nerve reinnervation occurred following facial nerve axotomy. METHODS: The normal distribution of motoneurons innervated both buccal and marginal mandibular branches and its reorganization after facial nerve reinnervation was observed using retrograde labeling with fluorescein. RESULTS: Under normal situation, the motoneurons contributing buccall and marginal mandibular branches were primarily distributed in the intermedial and lateral subnucleus in facial nucleus and almost completely overlapped. The two types labeled neurons organized closely, but there were no double-labeled neurons. Although the motoneurons contributing buccall and marginal mandibular branches were primarily overlapped 4 month post-anastomosis, the number of the labeled neurons obviously decreased and the organization got more scattered. There were 10% of buccall branches, 5% of marginal mandibular motoneurons in the dorsal subnuleus, 1% of buccall and 4% of marginal mandibular in dorsal ventral and medial subnucleus. The distribution pattern of the motoneurons 6 month post-anastomosis was similar to that of 4 month post-anastomosis, but the number of the labeled neurons increased, and there were 1%-2% double-labeled neurons. CONCLUSION: The distribution pattern of motoneurons innervated both buccal and marginal mandibular branches indicates that it should exist wide-spread communicating branches, and its reorganization after facial nerve reinnervation suggests that misdirected regeneration occurs among motoneurons innervating different branches.     

妇科恶性肿瘤术后骨质疏松症的防治

为探讨妇科恶性肿瘤术后骨质疏松症的预防措施,采用补充紫竹爱维和乐力胶囊来预防骨质疏松的发生,分别与未服药的妇科恶性肿瘤及良性肿瘤术后作对照,并对其对骨代谢指标血清骨性碱性磷酸酶(BALP)及血清抗酒石酸酸性磷酸酶(TRAP)的影响进行了临床观察.结果发现恶性肿瘤术后较良性肿瘤术后患者的BALP降低,TRAP增高,服用紫竹爱维与乐力胶囊的患者TRAP均低于未服药的恶性肿瘤术后患者,P＜0.05,均有显著性差异.表明妇科恶性肿瘤术后患者较良性肿瘤更易患骨质疏松症,服用紫竹爱维与乐力胶囊均能有效防治骨质疏松症,前者效果更佳,但应掌握性激素补充治疗(HRT)的应用指征.

高脂血症患者血小板体积及有关参数的研究

本文报道242例高脂血症患者血小板(PLT)、平均血小板数(MPLT)及平均血小板体积(MPV)等参数的测定结果,其中高胆固醇并高甘油三酯患者,PLT、MPLT及巨大血小板比例(Macro-PLT)高于正常,MPV正常;而单纯高胆固醇或高甘油三酯患者,上述指标与正常人无显著性差异。提示高胆固醇并高甘油三酯患者,存在血小板生成动力学异常,其血小板的破坏增加,生成率加速、但处于一种高水平的动态平衡之中。这可能是高脂血症出现高凝状态的原因之一。同时表明此类患者使用抗血小板疗法具有一定的合理性和必要性。     

Positional metabolism of benzo(a)pyrene in rat placenta and maternal liver. Comparison of induction effects

The biotransformation of [14C]benzo(a)pyrene (BP) was studied in vitro in the presence of microsomes prepared from isolated labyrinth and basal zone tissues of the rat placenta, as well as from maternal liver. Pregnant rats, day 14 of gestation, received beta-naphthoflavone (beta NF; 15 mg/kg, ip) or 3-methyl-cholanthrene (3MC; 30 mg/kg, ip). On day 15, placentae were dissected and microsomes were incubated with 17 microM [14C]BP and 2 mM NADPH. Metabolites formed in the incubation flasks were extracted and separated by HPLC utilizing a reverse phase column. Only trace BP metabolism occurred in basal zone microsomes from control, beta NF-, or 3MC-pretreated animals, as well as in labyrinth microsomes from control animals. In contrast, the preadministration of beta NF and 3MC increased labyrinth microsomal BP metabolism by 10- to 15-fold. Labyrinth and maternal liver microsomes from beta NF- and 3MC-treated animals actively converted BP to eight separate metabolites which co-chromatographed primarily with quinones and phenols. The overall formation of BP diol and phenolic metabolites by labyrinth microsomes was appreciably less than was observed for liver preparations. The very low activity of BP-4,5-oxide hydrolase in labyrinth microsomes compared to liver may in part explain the low level of formation of BP diols in placental microsomes. Labyrinth microsomes catalyzed the covalent binding of [3H]BP to calf thymus DNA, and this activity increased 5-fold following beta NF pretreatment. A comparison of induced tissues indicates that the amount of DNA binding in labyrinth microsomes is more extensive than would be expected by the level of total BP metabolism.(ABSTRACT TRUNCATED AT 250 WORDS)
