Salivary glands and noradrenergic transmission in diabetic rats.

1 Type 2 diabetes is associated with diverse oral pathologies in which salivary flow reduction is one of the causes of these oral abnormalities. Scarce literature exists regarding noradrenergic transmission and adrenergic-induced salivary flow in submaxillary and parotid glands of type 2 diabetic rats. 2 We studied noradrenergic transmission as well as the secretory response to alpha1- and beta-adrenoceptor stimulation in the parotid and submaxillary glands of type 2 diabetic rats.

Effects of HOE 140 on some renal functions in type I diabetic mice.

To investigate in mice the mechanisms underlying renal functions in a type I diabetes model, we have suppressed B2 kinin receptors local activities by their specific antagonist D-Arg [Hyp3-Thi5-D-Tic7-Oic8]BK (HOE 140). Mice made diabetic with low consecutive doses of streptozotocin (STZ) (45 mg/k BW during 5 days) were injected with HOE 140 (15 micrograms/twice a day) for 15 days. This drug did not modify glycemia of STZ treated animals but a significantly reduction of urinary proteins, nitrites and kallikrein was observed.
