查询词典 hypothalamus

In the combined treatment of the craniopharyngiomas, it is very important to prevent the irradiation injury of the surrounding structures such as the optic nerve, chiasm, hypothalamus and vascular structures. In those structures, the optic nerve and chiasm are the most sensitive ones to the irradiation, and their ability to bear the irradiation is about 9 to 12 Gy. So if the irradiation dose is lower than 9Gy, the treatment will be safe. We have not found any report about the bearability and side effect of the hypothalamus related to the gamma knife radiosurgery.

在治疗过程中，预防病变周围的重要结构如视神经，视交叉，丘脑下部和血管结构的放射性副损伤是非常重要的，在这些重要结构中，视神经和视交叉对放射线最为敏感，其耐受能力约为9～ 12 Gy，因此如果对这些结构的放射剂量在9Gy以下，治疗将是安全的，目前尚无有关丘脑下部的耐受剂量和放射性损伤的文献报道。

Immunohistochemical localization of inhibin α-subunit in normal mature rats was carried out by using Strept Avidin-Biotin-Peroxidase Complex .The results showed that there was positive immunoreactivity of the McAb to inhibinα-subunit in heart ,kidney , spleen , lymph ,adrenal gland and pancreas cells. It indicated that inhibinα-subunit existed in the above tissues , But no positive sites were seen in hypothalamus, pituitary, lung and liver, that means they have no inhibinα-subunit. Compared with the ovariectomized rats, the hypothalamus and pituitary of the rats injected with inhibin-α fragment（1～32）showed an positive reaction, suggesting that inhibin α-subunit could pass through the blood-brain barrier .

In order to investigate the effect of IFN-γon the expression of TNF-αin the hypothala- mus-pituitary-ovary axisof RU486-induced aborted SD rats, RU486 was used to establish the abortion model, then the aborted rats were administrated with different doses of IFN-γintraperitoneal injection, the method of immunohistochemical ultrasensitive SP was us- ed to study the variation of positive TNF-αcells in hypothalamus, pituitary, ovary and uterus in normal pregnant group A, aborted model group B and three different doses of IFN-γgroup C,D,E. The main goal of this research was to study whether the low dose of IFN-γcould have a protective function to pregnancy and the mechanism of its function so as to provide morph- ologic basis for the scientific using of IFN-γin the process of animal abortion control.

GnRH-ir fibers distribute in the various brain region from the olfactory bulb to the cerebellum. They are especially abundant in the hypothalamus, the preoptic area and the ventral telecephalon.

The differences are most obvious in the hypothalamus, but not in other areas.
