Effect of heating and enzymatic hydrolysis on casein cow milk sensitivity in Moroccan population

The objectives of the present work were first to evaluate the sensitivity to cow raw milk of the population of Fez, and then to study the effect of heating and pepsin hydrolysis on the allergenicity of casein. A cross-sectional study was carried out in Fez Hospitals, in which 1000 patients were recruited to establish a sera bank used to evaluate specific IgE to cow milk and to casein. Then, we evaluated the reaction of human IgE to heated and pepsin-hydrolysed casein. The results showed that 11.5% of the population studied self-reported reactions to foods. From them, 3.6% reported allergy to milk. Evaluation of specific IgE to cow raw milk showed that 11.9% of patients presented higher specific IgE levels. The treatments of casein indicated that both heating and pepsin hydrolysis totally decreased its binding on the human IgE.     

Synergistic effects of salmon gonadotropin-releasing hormone and estradiol-17beta on gonadotropin subunit gene expression and release in masu salmon pituitary cells in vitro

Effects of salmon gonadotropin-releasing hormone (sGnRH) and estradiol-17beta (E2) on gene expression and release of gonadotropins (GTHs) were examined in masu salmon (Oncorhynchus masou) using primary pituitary cell cultures at three reproductive stages, initiation of sexual maturation in May, pre-spawning in July, and spawning in September. Amounts of GTH subunit mRNAs were determined by real-time polymerase chain reaction, and levels of GTH released in the medium were determined by RIA. In control cells, the amounts of three GTH subunit mRNAs (alpha2, FSHbeta, and LHbeta) peaked in July prior to spawning. FSH release spontaneously increased with gonadal maturation and peaked in September, whereas LH release remained low until July and extensively increased in September. Addition of E2 to the culture extensively increased the amounts of LHbeta mRNA in May and July in both sexes. It also increased the alpha2 mRNA in July in the females. In contrast, sGnRH alone did not have any significant effects on the amounts of three GTH subunit mRNAs at all stages, except for the elevation of alpha2 and FSHbeta mRNAs in July in the females. Nevertheless, synergistic effects by sGnRH and E2 were evident for all three GTH subunit mRNAs. In May, sGnRH in combination with E2 synergistically increased the amounts of LHbeta mRNA in the males and alpha2 mRNA in the females. However, in July the combination suppressed the amounts of alpha2 and FSHbeta mRNAs in the females. sGnRH alone stimulated LH release at all stages in both sexes, and the release was synergistically enhanced by E2. Synergistic stimulation of FSH release was also observed in May and July in both sexes. These results indicate that a functional interaction of sGnRH with E2 is differently involved in synthesis and release of GTH. The synergistic interaction modulates GTH synthesis differentially, depending on subunit, stage, and gender, whereas it potentiates the activity of GnRH to release GTH in any situation.     

乙型肝炎病毒新的免疫逃避株的S基因序列分析

目的分析乙型肝炎患者体内ＨＢＶＳ基因的变异情况及对乙型肝炎的免疫预防的现实意义。方法采用巢式聚合酶链反应（ＰＣＲ）、Ｍ１３噬菌体克隆和核苷酸序列分析方法对一例乙型肝炎免疫失败儿童患者体内ＨＢＶＳ基因序列进行分析。结果发现该患儿所感染ＨＢＶ的Ｓ基因上有一个重要的点突变,即第５５１位碱基由野生型的Ａ变为Ｇ。该突变使乙型肝炎表面抗原（ＨＢｓＡｇ）１３３位氨基酸由甲硫（ＡＴＧ）变为缬（ＧＴＧ）。这一氨基酸替换恰恰发生在ＨＢｓＡｇ中和性α抗原决定簇区段（ａａ１２４～ａａ１４７）内。结论鉴于该患者接种乙型肝炎疫苗,其血清呈抗－ＨＢｓ阳性和ＨＢｓＡｇ阴性,推测其体内的ＨＢＶ为一个新的疫苗诱导的免疫逃避株     

阿德福韦酯联合抗纤方治疗对慢性乙型肝炎患者血清肝纤维化指标的影响

目的探讨阿德福韦酯联合抗纤方治疗对慢性乙型肝炎患者血清纤维化指标影响。方法选择100例慢性乙型肝炎患者,随机分为两组,对照组50例应用阿德福韦酯治疗;治疗组50例在对照组治疗基础上加用抗纤方。两组均予以一般保肝及对症治疗,疗程均为6个月。观察两组总有效率、肝功能变化,检测并比较两组治疗前后血清透明质酸(HA)、Ⅲ型前胶原(ⅢPC)、Ⅳ型胶原(ⅣC)、层粘蛋白(LN)的含量。结果治疗组总有效率为94.0%,明显高于对照组的78.0%(P<0.05)。治疗后两组的TBIL、ALT、AST值均较治疗前显著改善(P<0.01),其中治疗组TBIL、AST值的改善程度显著好于对照组(P<0.01)。治疗后两组的HA、LN、Ⅳ-C、ⅢPC值均较治疗前显著改善(P<0.01),治疗组的改善程度显著好于对照组(P<0.01)。结论阿德福韦酯联合抗纤方治疗能更好的改善患者临床症状,更有利于肝功能的恢复,更好地抑制肝脏的炎症反应,改善肝脏微循环,控制肝纤维化,改善肝脏病理组织。     

Evaluation of the sensitivity of Moroccans to shrimp tropomyosin and effect of heating and enzymatic treatments

The aim of this work was to evaluate the IgE-sensitivity to shrimp tropomyosin (ST) in a Moroccan population from Fez region, and then to study the effect of temperature and enzymatic digestion on the allergenicity of ST. This work was conducted with a questionnaire completed by a sera-bank, obtained from 500 patients recruited from Fez Hospitals. Their sera were analyzed for specific IgE-sensitivity to ST. From questionnaire, 9.8% reported allergy to fish and shellfish where shrimp was one of the most common species causing allergy in patients. Evaluation of specific IgE showed that 10.2% of patients present higher values. Further indirect ELISA and Dot-blot results indicated that ST showed a decrease in the human IgE binding under heating or pepsin hydrolysis. These results demonstrate that this population was sensitive to ST and the sensitivity could be reduced by heating and more where it was digested by pepsin.
