鼻息肉组织中白细胞介素—5和粒细胞巨噬细胞集落刺激因子水平测定及其意义

OBJECTIVE: To study the relationship between the concentration of interleukin-5 (IL-5) and granulocyte-macrophage colony-stimulation factor (GM-CSF) in nasal polyps and its significance. METHODS: The concentration of IL-5, GM-CSF was measured by enzyme linked immunosorbent assay (ELISA) in a total of 38 cases, and the number of eosinophils were counted in the same tissues. RESULTS: The statistical analysis showed that the concentrations of IL-5 and GM-CSF have significant difference (P < 0.05) between the nasal polyps and the control group. There is a positive correlation between the quality of IL-5/GM-CSF and the extent of eosinophils (r = 0.75/0.71). CONCLUSION: This study demonstrated that there are inductive compartments, namely the microenvironment, in which immune-effector and inflammatory cell function is modulated in nasal polyps. A special discussion has been made of eosinophils and IL-5/GM-CSF in the formation of nasal polyps, and the effect of the IL-5/GM-CSF in the accumulation of eosinophils.

催乳素在鼻息肉巨噬细胞中的表达及意义

OBJECTIVE: To detect the expression level and distribution of prolactin (PRL) in nasal polyp and to find out the significance of the mechanism of PRL in the invasion of nasal polyp. METHODS: Twenty-five polyp tissues were obtained from the patients who were subjected to nasal polypectomy in our Department. Inferior turbinate mucosa was used as control obtained from 12 patients with rhinogenous snoring. HE staining was performed for routine histopathologic examination. The expression of PRL in nasal polyps was observed by immunohistochemical staining, and six polyp tissues were estimated through double staining for determining cells which expressed PRL. RESULTS: (1) Positive expression of PRL was significantly stronger (t =4.004, P < 0.01) in 25 nasal polyp tissues (2.05 +/- 0.88) than that in 12 normal inferior turbinate mucosa (0.96 +/- 0.50). Positive expression of macrophage (CD68) was significantly stronger (t = 3.519, P < 0.01) in 25 nasal polyp tissues (1.85 +/- 0.83) than that in 12 normal inferior turbinate mucosa (0.93 +/- 0.52). (2) The PRL expressing cell mainly was the macrophage as demonstrated by double immunohistochemical method. CONCLUSION: PRL derived from macrophages of nasal mucosa may participate in the formation of nasal polyp through its local immune modulation.

雌二醇受体在鼻息肉组织的表达及其意义

为估价雌二醇（estradiol，E2）对鼻息肉发生的作用，对84例鼻息肉（男40例，女44例）、6例慢性肥厚性鼻炎（男2例，女4例）和4例正常鼻粘膜（男2例，女2例）的病理蜡块标本行免疫组化染色，以检测E2受体在各组织内的表达，并以子宫内膜组织作为对照。同时对鼻息肉标本行甲苯胺蓝染色，以检测肥大细胞的分布。结果发现61例鼻息肉组织有E2受体阳性细胞，且与性别无关。慢性鼻炎和正常鼻粘膜有E2受体阳性细胞者分别为2例和1例。E2受体阳性细胞与肥大细胞的形态、分布颇为类似，可能为同一细胞。结果提示E2对鼻息肉的发生有值得注意的作用。

Ultrastructure of mast cells in nasal polyps]

More mast cells were found in the base of nasal polyps and most of them showed varying degrees of degranulation. There were three types of granules in the cytoplasm, namely: high electron-dense granules with crystalline structure; low electron-dense granules with netlike structure and some granules containing a mixture of components of different electron density. The appearance of cell degeneration in nasal polyps and granules broken away from mast cells through the dissolved cellular membrane were noted. These findings suggested that mast cells degranulation in nasal polyps might be in some way different from the more rapid changes found in cells activated by the classical IgE-mediated pathway and showed that mast cell degranulation may play a part in formation and growth of the nasal polyps.

白细胞介素—6和8在鼻息肉组织中的表达

OBJECTIVE: To explore the role of interleukin-6,8 in nasal polyp formation and to search into the effect of allergy in the pathogenesis of nasal polyps (NP). METHODS: The expression and significance of interleukin-6,8 were studied in 36 nasal polyps and 36 serum samples of NP patients by radioimmunoassay. RESULTS: The mean value of IL-6 and IL-8 was (2.7658 +/- 0.3797) ng/L and (4.1877 +/- 0.1758) ng/L in all nasal polyp tissue homogenates. As compared with serum of NP patients, IL-6 and IL-8 were over expressed in nasal polyp tissue homogenates. No relation was found between the expression of IL-6/IL-8 and patients' gender, age and clinical stage. The expression of IL-6 and IL-8 in patients' serum, cord blood and normal serum showed no significant difference. CONCLUSION: IL-6 and IL-8 are strongly correlated with the formation of nasal polyp. Neither allergy nor infection play a role in the pathogenesis of nasal polyps.
