SD rat model

Masson s trichrome staining, as well as TEM observation. In this chapter, a systematic investigation and comparison of nerve repair is made using scaffolds made from PUCL-fl/t-PEG, PUCL-ran-PEG, autograft, PCL, silicone tube, and negative control in an SD rat model. 

Therefore, when it became clearly understood that atrazine is neither estrogenic nor a genotoxic, direct-acting carcinogen - and that the atrazine-associated tumor responses appeared only in female SD rats, a strain with a high, normally occurring incidence of mammary tumors - it became important to study the effect of high doses of atrazine on the SD animal model s own endocrine system and hormonal milieu.

Thyroid Giand While a number of studies have examined effects of NP exposure on thyroid function in aquatic species, there are relatively few studies available in mammalian models. Dose, duration of treatment, and gender aU appear to influence whether APs affect thyroid function. For instance, serum levels of T3 and T4, but not thyroid stimulating hormone (TSH), were elevated in ovariectomized female SD rats fed 4-NP at 20 or 80 mg/kg via a soy-free diet for up to 12 weeks (Schmutzler et al. 2004). In contrast, in an oral dosing (by gavage) 28-day...
