在不同紫外辐射波段下，南极棕囊藻（Ｐｈａｅｏｃｙｓｔｉｓａｎｔａｒｃｔｉｃａ）细胞的生长率、叶绿素ａ、细胞内ＤＭＳＰ含量和ＤＭＳ释放量变化的测定结果表明：ＵＶ－Ｂ对南极棕囊藻细胞生长率和叶绿素ａ含量有抑制效应，ＵＶ－... 详细信息

在不同紫外辐射波段下，南极棕囊藻（Ｐｈａｅｏｃｙｓｔｉｓａｎｔａｒｃｔｉｃａ）细胞的生长率、叶绿素ａ、细胞内ＤＭＳＰ含量和ＤＭＳ释放量变化的测定结果表明：ＵＶ－Ｂ对南极棕囊藻细胞生长率和叶绿素ａ含量有抑制效应，ＵＶ－Ｂ还可加快ＤＭＳＰ分解成ＤＭＳ和丙烯酸的分解速率，而ＵＶ－Ａ对该藻细胞的ＤＭＳＰ合成有强烈的抑制效应。鉴于在每年春季极地海洋浮游植物繁殖期间，南极棕囊藻在南极海冰带海洋浮游植物种群结构中占有的优势地位，以及该藻是极地海洋浮游植物中ＤＭＳ的主要释放者，推测南极“臭氧空洞”所增加的紫外辐射可能会对南极海域的ＤＭＳ释放率产生一定的影响。

大环内酯类抗生素,在临床上和在兽医中已具有十分突出的地位。为了进一步改善其效果及商业价值,近年来利用生物和化学方法半合成了许多衍生物。本文综述近年来在临床上及兽医中有前途的红霉素衍生物。已知红霉素在酸性条件下,会发生分子内环合而生成8,9—脱水—6,9半缩醛(hemir—etal)衍生物,然后进一步分子内环合。

Hairdressers are exposed to numerous skin-damaging factors, such as wet work, skin irritants, and thermal changes. Skin protection is a very important factor for the prevention of occupational skin disorders. Therefore, we evaluated a hand cream that was specially formulated for highly stressed skin with regard to its capability to reduce dry, rough, and scaly skin. The objective of this study was to conduct a controlled use test of a barrier repair cream containing pseudo-ceramide and demonstrate its efficacy for hairdressers with dry, sensitive hands and/or occupational skin disorders. A total of 30 hairdressers (29 females and 1 male, aged 20 - 67) participated in the study. All subjects suffered from dry hands. Subjects applied the test cream on their hands for 28 days (four weeks). For each subject, the skin surface topography of the hands was measured by the Surface Evaluation of Living Skin (SELS) system at day 14 (week 2) and day 28 (week 4). Dryness, scaling, cracking, redness, and itchiness were evaluated and graded by experts at week 2 and week 4, and then compared to baselines. All 30 subjects completed the study. A comparison of the changes from baseline to endpoint revealed a statistically significant reduction in skin roughness, scaling, and volume measured according to SELS. These data were confirmed by photographic documentation. The results were further supported by the expert evaluation. For the symptoms dryness and scaling, improvement could be observed in almost all regions of the hands. In addition, according to subjective assessments of overall hand skin condition and the hand cream, subjects reported clear improvement over time (p value below 0.001) and good efficacy of the product. In this study, the test hand cream showed excellent skin compatibility. Therefore, the hand cream may be effective for hairdressers with dry, sensitive hands and/or occupational skin disorders.

ovarian remnant syndrome occurs after bilateral oophorectomy when functioning ovarian tissue is left behind. It usually presents with pelvic pain and a palpable mass. The incidence of ovarian remnant syndrome is unknown. However, the condition is probably more prevalent than is generally appreciated. We report on a 37-year-old patient with ectopic manifestation of lost ovarian tissue in the abdomen following bilateral laparoscopic oophorectomy. This ovarian remnant located between the bladder and the greater omentum showed hormone activity and caused severe abdominal pain. Following laparotomy and complete resection of the remnant the patient was without symptoms. We conclude that lost ovarian tissue should in all cases be searched for and completely removed during the primary operation.
