引用

Journal of Reproduction and Contraception 2012年第4期23卷 199-208页

Objective To investigate the contraceptive mechanism of combination regimen of low- dose gossypol acetic acid （GA） with steroid hormones [desogestre/ethinylestradiol/ testosterone undeeanote（DSG/EE/TU）]. Methods Adult male rats were randomly divided into four groups. Group GH： rats were fed orally with gossypol acetic acid （GA, 12.5 mg/kg） and desogestrel （DSG, 0.125 mg/kg）/ ethinylestradiol （EE, 0.025 mg/kg）/testosterone undecanoate （TU, 100 mg/kg per day, qd X4 weeks or 10 weeks）; group G： a single dose of GA （12.5 mg/kg per day, qd X 4 weeks or I0 weeks）; group H： the same dosage of DSG/EE/TUas in group GH; group C： rats were treated with vehicle （1% methyl cellulose） as the control. Expression of protein kinase C alpha （PKC-a） and cyclin D1 in rat testes were tested mainly by immunohistochemistry （IHC） and Western blotting. Results IHC results showed that protein PKC- a was expressed mainly in interstitial tissue of testis among seminiferous tubule. The expression of PKC-oc in groups H and GH at week 10 was decreased greatly compared with that in group C. The protein cyclin D1 was expressed mainly in residual body of seminiferous tubule eavosurface and interstitial tissue among seminiferous tubule of testis. Western blotting results showed that the expression of PKC-a in groups H and GH at week 10 was decreased significantly compared with that in group C （P〈0.05）. The expression of cyclin D1 in groups G, H or GH at week 10 rose significantly compared with that in group C （P 〈0.05）.Conclusion The administration of low-dose gossypol acetic acid with steroid hormones for 10 weeks can decrease the expression of PKC-a greatly.

FOOD BIOSCIENCE 2023年第3期53卷 341-350页

To ensure food safety from animal origins and to prevent potential hazards caused by steroid hormones, there is an urgent need to develop a rapid detection method for steroid hormones in foods from animal origins. Three highly sensitive monoclonal antibodies (mAb) against testosterone propionate (Tp), stazolol (STA) and estradiol benzoate (EB) were prepared, with IC50 values of 0.13, 0.14 and 0.19 ng/mL, respectively. Tp-mAb is a group-selective mAb that simultaneously detects Tp, testosterone (T), methyltestosterone (MT) and testosterone phe-nylpropionate (TPP), and their IC50 values were 0.13, 0.77, 0.90, and 1.25 ng/mL, respectively. A novel multiplex lateral flow immunochromatographic strip (ICS) was further prepared, which could simultaneously detect Tp, STA, and EB in chicken and pork samples with limits of quantification (LOQ) of 0.32, 0.51, 0.35 mu g/kg and 0.36, 0.64, 0.43 mu g/kg, respectively. Based on the broad spectrum of Tp-mAb, ICS has been further devel-oped to detect Tp, T, MT and TPP simultaneously. This multiplex ICS rapid detection method was efficient, sensitive, and fast, for the simultaneous detection of multiple steroid hormones in actual samples. Its detection time is only 40 min, which it represents a favorable monitoring tool for the detection of steroid hormones in animal-derived foods from the marketplace.
