Th.s.s.udy aimed to evaluate th. milk clotting capacity (MCA), and cas.inolytic activity (CA) of crude coagulant from th. s.omach.0}of adult rabbits.(RC), and th.ir influence on th. compos.tion, proteolys.s. and texture of type Prato ch.es.. We tes.ed two ways.for s.lting th. abomas.m and th.ee levels.of ph.and times.for enzyme activation. Th. pres.nce of enzymes.and cas.inolytic activity in RC was.as.ayed by s.s.PAGE. Th. effects.of th.ee ph.levels.and th. milk’s.temperature on RC’s.water-h.lding capacity (Wh.) were evaluated. Brazilian Prato ch.es. type was.developed and its.proximate compos.tion, texture, and ch.nge during ripening were as.es.ed. Th. s.turated NaCl s.lutions.(37%, m/v) were more efficient for enzyme extraction from adult rabbit s.omach.0} and conditions.of ph.of 4.3 for 24 h.s.owed better performance for enzyme activation into RC. An early and more active proteolytic reaction of RC on bovine cas.inate was.appreciated at th. firs. 5 min of diges.ion wh.n compared to commercial ch.mos.n (CC). Th. water h.lding capacity of gel coagulated by RC was.optimum at ph.6.4 and 37°C and is.h.gh.y dependent on ph.and temperature parameters. Total dry extract and fat were h.gh.r for treatment coagulated with.RC. Convers.ly, h.rdnes., gummines., and ch.wability were lower in th. s.me treatment. Yield, protein content, and ch.nges.th.t occurred during th. ripening s.age of ch.es.s.were s.milar for both.treatments. demons.rating th.t cas.in proteolys.s.was.developed in a s.milar way. Coagulants.from adult rabbits. s.omach.0}can be us.d to make s.mi-cooked curd ch.es.s.

AIM： To as.es. th. frequency and as.ociated ris. fac- tors.of diabetic retinopath. among s.danes. individuals.with.diabetes.attending Makka Eye complex in Kh.rtoum, s.dan. METh.Ds. Th. cros. s.ctional h.s.ital bas.d s.udy recruited 316 individuals.with.diabetes.from Makkah.Eye Complex Retina Clinic. s.andard ques.ionnaire was.us.d to collect demograph.c data, medical h.s.ory and life s.yle ch.racteris.ics. Blood s.mples.were taken to meas.re h.Alc and lipid profile. Fundus.and s.it lamp examination were performed for s.reening of diabetic retinopath.. REs.LTs. Among 316 participants. 187 （59.2%） were males.and 129 （40.8%） were females. Th. mean age of participants.was.58.7＋_10.5y. Th. overall frequency of retinopath. was.261 （82.6%）. Th. percentages.of th. total participants.with.proliferative diabetic retinopath. （PDR） were 126 （39.9%） and non-proliferative diabetic retinopath. （NPDR） were 135 （42.7%）. importantly, duration of diabetes.mellitus.（DM）（72.2% of more th.n 10y）, being on oral h.poglycaemic drugs.（vers.s.ins.lin）, and h.pertens.on were all s.gnificant ris. factors.for diabetic retinopath. （P=0.00, 0.01 and 0.00 res.ectively）. Complications.ofdiabetes.like diabetic foot （17.7%）, h.s.ory of amputation （6.7%） and clinically s.gnificant macular edema （Cs.E）（47.4%） of th. eyes.were all s.gnificant ris. factors.（P〈0.05）. Logis.ic regres.ion analys.s.s.owed th.t duration of diabetes. h.pertens.on and Cs.E were found to be abs.lute ris. factors.（P=-0.007, 0.003 and 0,000 res.ectively）. Duration of DM of more th.n 10y h.ve more th.n double ris. （OR--2.8）, wh.le h.ving h.pertens.on triples.th. ris. of retinopath. （OR=3.1）. CONCLUs.ON： h.gh.rates.of diabetic retinopath. are noted among individuals.with.diabetes.attending Makkah.Eye h.s.ital in capital Kh.rtoum. Urgent s.rategies.are needed to monitor and treat h.pertens.on and optimize diabetes.control in individuals.with.diabetes. More inves.ment in diabetes.s.rvices.is.urgently needed.

经典的“地幔柱假说”能够很好解释年龄随空间位置线性变化的大洋板内火山链的成因.而位于西太平洋的众多海山群,空间分布广、年龄-位置关系杂乱,很难用经典的“地幔柱假说”来解释,其成因存在争议.本研究选择西太平洋麦哲伦海山群h.mler、Vlinder和Il’ich.v海山熔岩,对其进行40Ar-39Ar年代学、主量和微量元素以及s.-Nd-Pb-h.同位素分析,来揭示其岩石成因和形成的深部动力学机制. h.mler、Vlinder和Il’ich.v海山熔岩属于碱性玄武岩、碧玄岩/霞石岩和粗面岩, MgO>8wt.%的熔岩具有较高的CaO、FeOT和TiO2含量,是碳酸盐化榴辉岩熔融的熔体与橄榄岩反应的产物.这些熔岩具有较高的Zr/h.比值(40.6~45.2)和Zr-h.负异常,指示它们的地幔源区存在碳酸盐组分. h.mler、Vlinder和Il’ich.v海山熔岩富集不相容元素,其s.-Nd-Pb-h.同位素显示EM1(1型富集地幔)特征,与Rarotonga和s.moa热点相似.虽然产出于同一个海山, Il’ich.v碱性玄武岩与Il’ich.v碧玄岩的同位素组成明显不同:前者具有更为亏损的s.-Nd-h.同位素特征.结合板块构造恢复结果, h.mler(100.1Ma)、Vlinder造盾前(100.2Ma)和造盾期后((87.5±0.4)Ma)以及Il’ich.v((56.4±1.2)Ma)海山熔岩的形成时间明显偏离了南太平洋Macdonald、Arago、Rarotonga和s.moa热点的运移轨迹,因此它们并非来源于深部地幔柱的直接熔融,更可能是浅部过程的产物.麦哲伦海山群所在的大洋板块的一个典型特征是:岩石圈断裂带在该区域广泛分布.我们提出,在中白垩世当麦哲伦海山群所在的太平洋板块经过Rarotonga地幔柱上方时, Rarotonga地幔柱直接熔融形成Vlinder(造盾期)、Pako和Ioah.山.随着地幔对流分散在周围软流圈中的Rarotonga和s.moa地幔柱物质,在岩石圈裂隙处发生减压熔融,形成h.mler和Vlinder造盾前和造盾期后熔岩;Il’ich.v海山碱性玄武岩和碧玄岩是岩石圈裂隙诱发的软流圈中不均一富集组分熔融的产物.这种不均一组分最可能是滞留在软流圈中的不同地幔柱的物质,也有可能是残留在软流圈中的再循环的地球表层物质.
