3.[Methods]①Orpiment nanoparticles were prepared chemically and characterized by transmission electron microscope (TEM) and energy dispersive spectrometry (EDS).
4.a very poisonous metallic element that has three allotropic forms; arsenic and arsenic compounds are used as herbicides and insecticides and various alloys; found in arsenopyrite and orpiment and realgar.
5.ACRIDINE MUTAGEN ICR-170 INDUCED DEVELOPMENTAL SUPPRESSION OF OVARY AND VITELLINE GLAND IN FEMALE SCHISTOSOMA JAPONICUM
6.Methods: 120 female, 3-month-old Wistar rats were randomly divided into 6 groups:sham(sham-operation),OVX(ovariectomy),DES(OVX+diaethylstilbestrol),L-SI(OVX+low dose soy isoflavone ),M-SI(OVX+moderate dose soy isoflavone ) ,H-SI(OVX+high dose soy isoflavone ) (n=5 in a group).
7.The period of time after its exuviate is thinner, weigh water crab; After this flesh gradually plump, the male crab of fat and not the female crab of be fertilized, weigh fleshy crab; And the female body after be fertilized, after classics fatten is ovarian and mature, "Connect body to coagulate fat, red yellow miscellaneous mix, the knot is pomegranate seed " , call cream crab.
8.2、Two estron derivatives and two isoflavone derivatives were synthesized and their structures were confirmed by UV, ~1HNMR.
9.Mature male Gambusia affinis vitellogenin was induced by E2 through exposure to the waterborne.
10.Vitellogenin was induced in red drum and genuine porgy by intraperitoneal injections of 17β-estradiol. After one week induction, the blood was collected from caudal vessel and then centrifuged. Purification of the VTG was performed by gel permeation chromatography of Sephacryl S-300 high resolution and ion exchange chromatography on a DEAE-Sepharose column.
