Abstract

To investigate the effect of sodium cromoglycate on experimental endometriosis in rats. Endometriosis model was established in 36 unpregnant female SD rats by transplanting autologous fragments of endometrium to the inner surface of the abdominal wall. The endometriotic lesions were measured by a second laparotomy 2 weeks after surgery. Then the rats were randomly divided into four groups (n=8 in each group) to receive intraperitoneal injection of different doses of sodium cromoglycate for 2 weeks: high-dose group (20 mg·kg⁻¹·d⁻¹); low-dose group (10 mg·kg⁻¹·d⁻¹); the negative control group and the blank control group. The animals were sacrificed and the size of the lesions were measured. The endometriosis model of SD rats was identified by HE staining and immunohistochemical staining of keratin and vimentin. The total number of mast cells and their degranulation were measured by Toluidine blue staining; the concentrations of TNF-α in serum were measured by enzyme linked immunosorbent assay; the concentrations of estradiol in serum were measured by enzyme immunoassay; the expression of tryptase and nerve growth factor (NGF) were measured by immunohistochemical staining. The number of activated mast cells (MC) by Toluidine blue ...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
