牙周病变组织谷胱甘肽过氧化物酶的测定

目的：探讨谷胱甘肽过氧化物酶与牙周组织病的关系。方法：选择了１２例慢性龈炎，１３例单纯性牙周炎，９例健康对照，采用ＤＴＮＢ显色法测定酶的活性，对其病变龈组织做ＧＳＨ－ＰＸ测定，并分析了临床指标与实验室指标的相关关系。结果：１．龈炎组，ＧＳＨ－ＰＸ含量为２９３．７４±１２１．７０，牙周炎组为２４２．９７±１１０．５９，对照组７８１．２５±１１３．３９，龈炎组、牙周炎组的ＧＳＨ－ＰＸ活性显著低于对照组（Ｐ＜０．０１），龈炎组与牙周炎组ＧＳＨ－ＰＸ活性无显著差异（Ｐ＞０．０５）。２．龈炎组牙龈指数与ＧＳＨ－ＰＸ活性成负相关（ｒ＝－０．７２２５，Ｐ＜０．００５），牙周炎组牙周袋深度，附着丧失量与ＧＳＨ－ＰＸ活性成负相关（ｒ＝－０．７６５３，ｒ＝－０．８５７８，Ｐ＜０．００２５）。结论：牙周病变组织ＧＳＨ－ＰＸ活性降低可能有两方面的原因，其一是牙周病是细菌引起的非特异性炎症，由于细菌的存在，局部自由基生成增多对ＧＳＨ－ＰＸ消耗增大；其二是由于全身因素的影响局部ＧＨＳ－ＰＸ合成减少。     

口腔颌面部恶性肿瘤患者T细胞亚群状况初探

测定患者Ｔ细胞亚群及其之间的比例关系，能够了解机体的免疫功能状况，对患者的病情，治疗、预后较为全面地掌握。作者应用ＯＫＴ单克隆抗体（ＭｃＡｂ）检测３０例正常健康人和２６例口腔颌面部恶性肿瘤患者外周血的ＯＫＴ４（正常人４８．３２±８．４５；患者２７．４１±７．８９，ｐ＜０．０１），ＯＫＴ８（正常人１９．８２±６．４６；患者３２．１５±７．１４，ｐ＜０．０１），ＯＫＴ４／ＯＫＴ８（正常人２．４７±０．５４；患者１．０２±０．４６，ｐ＜０．０１），比值下降，表明口腔颌面部患者机体免疫功能受到抑制，清除肿瘤细胞的能力下降     

牙周病患者唾液中GSH－PX含量测定的初步观察

为了探讨唾液中谷胱甘肽过氧化物酶（ＧＳＨ－ＰＸ）与牙周病的关系，作者选择１８例慢性龈炎患者，２０例牙周炎患者，１７例健康者对其口腔混合唾液做ＧＤＨ－ＰＸ的测定，结果表明：慢性龈炎组ＧＳＨＰＸ含量为４３．２６±１４．７５牙周炎组为４０．１３９±１３．９８，健康组为６３．４８±１５．６９，龈炎组，牙周炎组ＧＳＨ－ＰＸ含量明显低于健康组（Ｐ＜０．０５），而龈炎组与牙周炎组无显著住差异（ｐ＞０．０５），牙周病患者唾液ＧＳＨ－ＰＸ含量降低可能有两方面的原因，其一是牙周病是细菌引起的复杂炎症由于细菌的的存在，局部自由基（ＦＲ）生成增多对ＧＳＨＰＸ消耗增大，其二是由于全身因素的影响局部ＧＳＨ－ＰＸ合成减少，由此推论局部自由基增加，抗氧化能力下降可能在牙周病发病过程中起重要作用。     

头颈部肿瘤血清铁蛋白（SF）测定的临床意义（附144例报告）

本文对６５名健康献血者，４５名头颈部恶性肿瘤和３４例良性肿瘤患者进行血清铁蛋白（ＳＦ）测定。结果表明，恶性肿瘤组（ＳＦ）测定值（±ＳＤ）为２９４．７８±１４５．０４ｎｇ／Ｌ，良性肿瘤组（ＳＦ）测定值（±ＳＤ）为１１３．０３±４５．４３ｎｇ／Ｌ，健康对照组（ＳＦ）测定值（±ＳＤ）为６８．５４±３０．１５ｎｇ／Ｌ，。恶性肿瘤与良性肿瘤，恶性肿瘤与健康对照组，及良性肿瘤与健康对照组之间均有显著性差异（ｐ＜０．０１），从而提示ＳＦ在头颈部恶性肿瘤诊断中具有一定临床意义

本文介绍通过采用ＥＬＬＩＳＡ法对６１份正常人血清及４９份口腔颌面部肿瘤患者血清进行癌胚抗原（ＣＥＡ）含量测定，得出各组ＣＥＡ含量结果（ｕｇ／Ｌ）。经统计学处理，正常人组（Ｘ±ＳＤ，２．９４±１．５５）与良性肿瘤组（Ｘ±ＳＤ，４．１２±２．００）对比，Ｐ＜０．０１。正常人组与恶性肿瘤组（Ｘ±ＳＤ，５．７５±２．７７）对比，Ｐ＜０．０１。良性肿瘤组与恶性肿瘤组对比，Ｐ＜０．０５．血清ＣＥＡ含量测定阳性率：良性肿瘤组为４．８％，恶性肿瘤组为２５％。由此可以推测口腔颌面部恶性肿瘤患者血清ＣＥＡ含量明显高于正常人和良性肿瘤患者。本文实验结果提示，在口腔科临床开展血清ＣＥＡ含量的测定，对诊断颌面部恶性肿瘤具有一定的辅助作用。     

口腔颌面部肿瘤病者血清SIL-2R水平的临床价值

Relationship between medical treatment and oral dryness diagnosed by oral moisture-checking device in patients with maxillofacial prostheses

PurposeThis study aimed to examine the relationship between oral dryness and medical treatment (medication, radiotherapy) for patients with maxillofacial prostheses.MethodsSixteen patients with maxillofacial prostheses were examined according to the following procedure. For evaluating oral dryness, oral moisture was measured at the lingual mucosa and the right and left buccal mucosa using a Moisture Checker Mucus^®. The mean value of each measurement was recorded as the moisture value (%). A value of 29% was used as a reference value to divide patients into a normal group and an oral dryness group. Patients with a moisture value of more than 29% were classified as normal. The clinical histories of the patients (including their current medication use and radiotherapy history—dose of radiation and period after radiation) were surveyed from their clinical records. Patients rated themselves on their feelings for oral dryness using a faces scale.ResultsThe moisture value was significantly lower in the oral dryness group than the normal group. There was a significant difference in moisture values between the number of patients with and without radiotherapy, but not patients with and without medications. The moisture value had a significant negative correlation with the dose of radiation and a positive one with the period after radiation. The score of faces scale showed a significant negative correlation with moisture value.ConclusionThe patients with maxillofacial prostheses who had undergone radiotherapy need moisture retention because of oral dryness depending on the dose of radiation and the period after radiation.     

Pingyangmycin with triamcinolone acetonide effective for treatment of lymphatic malformations in the oral and maxillofacial region

ObjectiveThe aim of this study was to evaluate the therapeutic effects of intralesion injection of pingyangmycin in combination with triamcinolone acetonide or pingyangmycin alone on lymphatic malformations in oral and maxillofacial regions.MethodsTwenty-nine cases with lymphatic malformations in the oral and maxillofacial region were divided into experimental and control groups. Thirteen patients in the experimental group underwent intralesion injections of pingyangmycin in combination with triamcinolone acetonide, and 16 patients of control group underwent intralesion injections of pingyangmycin alone. The effects of treatments were assessed by measuring lesion volume and facial deformity before and after treatment.ResultsTwo years after the treatment, the volumes of macrocystic and microcystic lesions were 3.7% ± 0.3 and 4.2% ± 0.4 of pre-treatment volume in the experimental group, respectively, whereas the volumes of macrocystic and microcystic lesions in control group were 15.4% ± 1.3 and 24.1% ± 3.1, respectively. Facial appearance was satisfactory in all subjects in the experimental group, whereas facial asymmetry remained in varying degree in control group.ConclusionIntralesion injection of pingyangmycin with triamcinolone acetonide was more effective than pingyangmycin alone for treatment of lymphatic malformations in oral and maxillofacial regions.     

Salivary Immunoglobulins in Patients With Juvenile Periodontitis and Their Healthy Siblings

The concentrations of the salivary immune-globulins IgA, IgG and IgM were determined with a solid phase radioimmunoassay in the unstimulated whole saliva of 21 patients with juvenile periodontitis (JP), their 27 healthy siblings and 17 healthy age-matched controls. In the JP group the concentrations of IgA were increased, averaging 188 ± 32.5 (SE) mg/L as compared with the mean of 139 ± 21.2 mg/L in their healthy siblings and 130 ± 24.5 mg/L in the controls. An elevation was found in the amount of IgG in the JP patients: 45.6 ± 12.5 mg/L as compared with 18.1 ± 5.9 mg/L in the siblings and 21.0 ± 5.6 mg/L in the controls. The mean IgM was 22.5 ± 5.4 mg/L in the JP group, 13.3 ± 2.9 mg/L in the siblings and 8.7 ± 1.6 mg/L in the controls, indicating an increase of IgM in the JP group and the siblings. A significant difference was found in the mean IgM values in the juvenile periodontitis group when compared to the control group. (0.02 > P > 0.01).     

Study of NK cell activity in patients with oral maxillofacial squamous cell carcinoma

NK cell activity of peripheral blood lymphocytes against K562 cell line were tested with 125IUdR release assay in 50 normal controls and 50 patients with oral maxillofacial benign tumors and 178 patients with oral maxillofacial squamous cell carcinoma. The data show NK cell activity of patients with primary squamous cell carcinoma is lower than that of normal controls and that of patients with benign tumors (P less than 0.001 and P less than 0.001). NK cell activity of patients with benign tumors is not different from that of normal controls (P greater than 0.05). NK cell activity of patients with II and III grade squamous cell carcinoma is lower than that of patients with I grade squamous cell carcinoma (P less than 0.01). Stage-related NK cell activity is not observed and there is no significant difference between patients with and without lymph-node metastasis. NK cell activity of patients with recurrent squamous cell carcinoma is not only lower than non-recurrent patients and normal controls (P less than 0.001) but also lower than primary squamous cell carcinoma patients (P less than 0.01). The non-recurrent patients have normal NK cell activity. The results indicate that the patients with oral maxillofacial squamous cell carcinoma have impairment of NK cell function. NK cell activity of the patients depresses within one week of operation and returns preoperative level two weeks after operation. Chemotherapy inhibits NK cell activity, which may not return two weeks after chemotherapy. These give reference to clinicians. NK cell activity may be a parameter in monitoring the immunofunction of oral maxillofacial malignant tumor patients.     

前臂皮瓣与股前外侧皮瓣修复口腔颌面部缺损的效果比较

目的 比较分析前臂皮瓣和股前外侧皮瓣修复重建口腔颌面部肿瘤术后缺损的临床效果。方法 收集 54例行口腔颌面部恶性肿瘤根除术并接受游离皮瓣修复术的患者资料,其中33例患者采用前臂皮瓣修复（A组）、21例采用股前外侧皮瓣修复（B组）。应用SPSS 19.0软件包分析2组患者的手术持续时间、皮瓣存活率、受区功能与外形恢复情况、供区恢复情况及患者满意度等。结果 A组手术时间为（41.6±8.9）min,B组为（47.2±10.2）min,差异具有统计学意义（P<0.05）;A组皮瓣存活率（93.9%）高于B组（90.5%）,但差异无显著性（P>0.05）;受区功能与外形恢复情况2组基本相似;供区功能恢复B组优于A组,A组永久性功能障碍比率为24.2%,B组仅有暂时性功能障碍且比率为9.5%;A组供区色素沉着发生率显著高于B组（P<0.05）;B组的满意度显著优于A组（P<0.05）。结论 应用前臂皮瓣与股前外侧皮瓣修复,术后受区功能、外形恢复情况相似。前臂皮瓣成功率高,但需要植皮,且术后供区易形成永久性功能障碍;股前外侧皮瓣供区隐蔽,可以提供的组织量大,术后供区功能障碍很少,患者满意度高,但是手术难度大于前臂皮瓣,技术要求高。
