[Distribution of melanin in the larvae of ].

We examined the distribution of melanin during the development of the larvae of except the eyes with histological method. The results showed that after hatching, the appearance sequence of melanin in different organs were following an order of the outer membrane of neurocranium, the pericardial cavity and the dorsal skin, and the peritoneum and the spinal cord. Specifically, melanin appeared in the outer membrane of neurocranium around 5 DAH (days after hatching), in the pericardial cavity and the back skin at 7 DAH, and in the peritoneum and the spinal cord at 10 DAH.

[RORγt expression in the pulmonary tissue of asthmatic mice and the inhibitory effects of budesonide].

Objective: To study the effect of budesonide (BUD) on RORγt expression in the pulmonary tissue of asthmatic mice and mechanisms of BUD in the treatment of asthma.

Methods: Blab/c asthmatic mouse model was induced by ovalbumin (OVA). Thirty female mice were randomly divided into three groups: control, asthmatic and BUD-treated.
