高pH促进黄瓜离体子叶花芽分化的适宜处理时间和部位

在已知ｐＨ７．０预培养２ｄ能有效地促进花芽形成的基础上，进一步研究了其适宜的处理时间和部位。结果显示，高ｐＨ处理最有效的时间是子叶离体后的２４ｈ内，最有效的部位是子叶本身，尤其是子叶柄。同时提示ｐＨ能直接作用于子叶形态发生区域．     

黑加仑色素的分离及组成初步鉴定

利用纸层析对黑加仑色素进行分离，并进行分析鉴定，初步推测黑加仑色素４个组分分别为矢车菊素－３－芸香糖苷（Ｃｙ－３－ｒｕｔ）、飞燕草素－３－芸香糖苷（Ｄｐ－３－ｒｕｔ）、矢车菊素－３－葡萄糖苷（Ｃｙ－３－ｇｌｕ）、飞燕草素－３－葡萄糖苷（Ｄｐ－３－ｇｌｕ）．     

Comparison of retinal pigment epithelium cell preparations from the bovine eye

Summary Retinal pigment epithelium (RPE) cells were collected from, bovine eyes using a new method. The cells were harvested by vortexing the RPE and underlying choroid in 0.05 M citrate phosphate buffer, pH 5. RPE cells recovered by this method were compared to a standard method by microscopic examination of cell integrity, estimation of total protein, and assay of 11-cis and all-trans retinyl ester hydrolase (REH) activities. Results suggest that this method collects RPE cells of good integrity and with a significantly higher protein yield than the conventional method. Additionally, a much higher retinyl ester hydrolase activity was noted. Therefore we propose that this procedure offers a new and convenient method in the collection of RPE proteins for certain purposes such as enzyme purification.

柑桔皮色素的提取及性能表征

对柑桔皮进行了色素提取并对提取色素进行性能表征.用无水乙醇作为提取剂,原料与提取剂质量体积比为1∶9,分三次提取,石油醚萃取醇提取液,分别得油溶性和水溶性色素.该色素理化性质实验表明:水溶性色素最大吸收峰波长为475 nm,而油溶性色素最大吸收峰波长在440 nm,色素溶液的耐光性及耐热性较好,色素溶液自然光照60 d吸光度稳定在1.67×10-2,色泽基本不变,温度在20～90 ℃之间吸光度基本保持不变,高于98 ℃时出现混浊且有退色;常用食品添加剂蔗糖、柠檬酸、防腐剂对色素无不良影响,吸光度稳定为2.0×10-2,颜色不变;溶液的酸度对色素有一定影响,在pH＝2～11范围内,色素溶液吸光度稳定为1.97×10-2;色素的抗氧化性较强,0.1%的H2O2水溶液中,10 d内吸光度稳定,但耐还原性能力差,5 d内基本褪色.     

西宁地区海甘蓝农学性状的观察与分析

对西宁地区海甘蓝外部形状、生育期及花芽分化的观察及种子成份的测定结果：海甘蓝株高为82—85cm，生育日数116—134d，千粒重5．25—6．20g；播种到开花约80d，花期25d左右。经测定，其种子含油量为47．14％，其中芥酸含量高达63．17μmol／g，硫甙含量为72．49—84．70μmol／g。     

Regulation of the retinal interphotoreceptor matrix Na by the retinal pigment epithelium during the light response

We examined the rabbit retinal pigment epithelium (RPE) for Na transport properties which would allow it to buffer undesirable changes in Na concentrations in the interphotoreceptor matrix (IPM) during light and dark cycles. The RPE is selectivity permeable to sodium. Open and short circuit transport studies with RPE indicate a circulating (choroid to retina and back) Na current which does not compromise the electrical integrity of the blood brain barrier but together with the Na permeselectivity is of sufficient magnitude to buffer both upwards and downwards movements of IPM [Na] during light or dark responses.
